It was the Romanian expatriate writer E. M. Cioran writing in French (and translated into English by the indefatigable Richard Howard) who first made me aware of Joseph-Marie, Comte de Maistre. Cioran’s Anathemas and Admirations has a chapter on de Maistre, the latter himself an intemperate expatriate gifted with a literary style so powerful that it wins the reader’s attention for doctrines so marginal as to be laughable — if only they had not been taken so deadly seriously by men who have died for them. But not everything in de Maistre is as trivial or marginal as his monarchism and his defense of the Ancien Régime.
Along with Edmund Burke, de Maistre (when he is remembered today) is remembered as a proto-conservative, staking out positions that would later become doctrinaire among conservative thinkers. Both were great stylists, but Burke was really a poet — did he not write one of the eighteenth-century tracts on the sublime that gentlemen of good taste wrote in those times? — while de Maistre was an original, ruthless, and brutal thinker, i.e., he was everything that a philosopher ought to be. But today de Maistre is held in low opinion because of his at times virulent racism (as though this were worse than virulent monarchism, or virulent sexism, etc.).
There are two sides of the coin of ad hominem arguments: either love or hatred of a man can lead us to embrace or reject his ideas. We need to try to see beyond both de Maistre’s fearsome if not untouchable reputation and the beauty of this style, if we are to engage with de Maistre the thinker — and this is a task worth the effort, because de Maistre has some interesting ideas that deserve exposition. His low reputation today might lead us to ignore these ideas, or his literary style might lead us to assent to ideas that, while interesting, certainly do not deserve our assent.
The intransigence of de Maistre invites the reader to shout back at him, even to shout him down, with a long and detailed catalog of the absurdities that have been perpetrated upon the world by men who believed in the doctrines that de Maistre defends. I doubt any of this would have made the slightest impression on de Maistre, whose own obvious contempt for such an approach comes across in every dismissive formulation that is presented as though no counter-veiling principle were even possible, even thinkable. With such a mind it would be utterly irrelevant to debate details; I have no doubt that de Maistre would have dismissed every challenge to his examples and instances with a contemptuous wave of the hand and a disapproving expression. In reading de Maistre, therefore, it behooves us to think only in terms of principles.
What are de Maistre’s principles? What is the essence of de Maistre’s thought? It is easy to take the wrong lesson from such a vigorous and expressive writer. The least imaginative and least creative among us read the likes of Burke and de Maistre and believe that they have found the whole meaning in a blueprint for contemporary society. But this is a mere detail, an accident of historical circumstances that might be construed in dramatically different ways in different periods of human history. What is of the essence of de Maistre’s thought is something not at all obvious, and it is his finitistic perspective.
I have previously quoted from de Maistre’s An Essay on the Generative Principle of Constitutions — a short, incisive, and suggestive work, i.e., everything that a philosophical work should be — in Fairness and the Social Contract and Why Revolutions Happen. Comte de Maistre begins his Essay by recounting the counter-intuitive nature of political science, citing several examples of putative political “common sense” and how experience has shown these to be “disastrous.” This points to an unexpected empiricism in de Maistre’s thought. Echoing but altering Thucydides’ famous aphorism, history is philosophy teaching by example, de Maistre wrote that history is experimental politics.
1. No government results from a deliberation; popular rights are never written, or at least constitutive acts or written fundamental laws are always only declaratory statements of anterior rights, of which nothing can be said other than that they exist because they exist.
2. God, not having judged it proper to employ supernatural means in this field, has limited himself to human means of action, so that in the formation of constitutions circumstances are all and men are only part of the circumstances. Fairly often, even, in pursuing one object they achieve another, as we have seen in the English constitution.
And this is how they appear, in a slightly revised form, in de Maistre’s Essay:
1. No constitution arises from deliberation. The rights of the people are never written, except as simple restatements of previous, unwritten rights.
2. [In the formation of constitutions] human action is so far circumscribed that the men who act become only circumstances. [It is even very common that in pursuing a certain end they attain another.] 3. The rights of the PEOPLE, properly so called, proceed almost always from the concessions of sovereigns and thus may be definitely fixed in history, but no one can ascertain the date or the authors of the rights of the monarch and the aristocracy.
This in itself, in its most tightly circumscribed formulation, I cannot reject — human action is most certainly circumscribed, and unintended consequences often outweigh intended consequences. Indeed, de Maistre’s thought here closely echoes my own formulations in terms of the permutations of human agency, and in so doing de Maistre reveals his eschatological conception of history, affirming non-human agency as the source of political constitutions.
Further to this eschatological conception, Comte de Maistre quotes the theologian Bergier:
Law is only truly sanctioned, and properly law, when assumed to emanate from a higher will, so that its essential quality is to be not the will of all [la volonte de tous]. Otherwise, laws would be mere ordinances. As the author just quoted states, “those who were free to make these conventions have not deprived themselves of the power of revocation, and their descendants, with no share in making these regulations, are bound even less to observe them.”
Essay on the Generative Principle of Political Constitutions and other Human Institutions, M. the Count de Maistre, the citation is from Bergier, Traite historique et dogmatique de la Religion, III, ch. 4 (after Tertullian, Apologeticus, 45)
Bergier has here put his finger on something important, though of course the lesson I take from it is rather different than the lesson that de Maistre takes from it. The same idea finds a very different expression in Gibbon, and I have quoted this several times:
“In earthly affairs, it is not easy to conceive how an assembly equal of legislators can bind their successors invested with powers equal to their own.”
Edward Gibbon, History of the Decline and Fall of the Roman Empire, Vol. VI, Chapter LXVI, “Union Of The Greek And Latin Churches.–Part III.
I have called this Gibbon’s Principle of Inalienable Autonomy for Political Entities, or, more briefly, Gibbon’s Principle. Bergier and de Maistre invoke a distinction between laws and ordinances, with ordinances being mere human things subject to change, while laws are laid up in heaven. This is de Maistre’s realism.
The political theologizing of de Maistre is what is most predictable and least interesting in his thought; it only becomes interesting as a consequence of his finitism. The implications of de Maistre’s finitism, once extrapolated to its logical conclusion throughout his political thought, converges upon a radical finitism in political science, and this I cannot accept or endorse. More interesting than his theologizing is de Maistre’s political realism — and by “realism” I do not mean that “political realism” used in discussions of policy, that prides itself on its rejection of humanitarianism and of moral and political ideals, but de Maistre’s Platonic realism in politics that, on the contrary, raises up moral and political ideals as the only true reality.
The strong position de Maistre takes on ineffability is related to his Platonic realism: constitutions are real in a Platonic sense, but our knowledge of them is imperfect, and if we try to write them down we will only get it wrong, much as a mathematician using a compass to draw a circle inscribes only an imperfect image of a circle that represents, for pedagogical reasons, the “real” and “true” circle to which the imperfect drawing refers. The harder we try to inscribe a perfect circle, the more we are going to depart from the Platonic form of a circle, and the more we try to write down the perfect constitution, the more it departs from the Platonic form of a constitution. In de Maistre, written law is not only derivative of unwritten law, i.e., the mere appearance or a more fundamental reality, but it is, moreover, always wrong because the unwritten fundamental reality is essentially ineffable.
This is how de Maistre himself formulates it in his Essay:
1. The fundamental principles of political constitutions exist prior to all written law.
2. Constititional law is and can only be the development or sanction of a pre-existing and unwritten law.
3. What is most essential, most inherently constitutional and truly fundamental law is never written, and could not be, without endangering the State.
4. The weakness and fragility of a constitution are actually in direct proportion to the number of written constitutional articles.
This is really quite close to Brouwer’s intuitionism; indeed, we might call de Maistre’s thought intuitionistic political science. Both Brouwer and de Maistre place a strong emphasis on the ineffability of experience, and the ways in which language misleads and falsifies, but de Maistre’s ineffability is predicated upon realism while Brouwer was what we might call a proto-anti-realist. Intuitionism after Brouwer went on to inspire a generation of philosophers to formulate anti-realist positions that owe much to Brouwer’s inspiration.
Thus de Maistre’s realism coupled with finitism and an eschatological conception of history stake out a unique (or nearly unique) position in the history of thought. It would be entirely possible to formulate this Platonic realism in politics in an infinitistic context (just as de Maistre could have justified his finitism according to other conceptions but in fact chose to justify it in theological terms, invoking an eschatological conception of history), but de Maistre is thoroughly finitistic in his orientation.
Comte de Maistre uses an eschatological conception of history to provide the ideological superstructure of justify his theological exposition of finite human agency, but he could make the same point invoking a cataclysmic conception of history or a naturalistic conception of history. Even a modified and qualified formulation of the political conception of history, which makes human agency fundamental and central to history, would be consistent with de Maistre’s finitism, so that the theological justification, however much weight de Maistre himself might have attached to it, is of little intrinsic interest. The point I am making is that de Maistre’s theology is dispensable in defining his theory, while de Maistre’s finitism is indispensable.
Joseph de Maistre’s finitistic political theory represents something of an antithesis to an infinitistic conception of political society such as I outlined in what I called Gödel’s Lesson for Geopolitics (and something I touched upon again in Addendum on Technological Unemployment).
I hope to return to this idea in future posts, and to be able to show why this is important, because I know that this sounds rather recondite and marginal, but it is neither. One of the most persistent themes of Western historiography in the modern period is the idea of progress, which is attacked at least as often as it is put forward as an interpretation of history (not long ago in Progress, Stagnation, and Retrogression I mentioned my surprise that Kevin Kelly offered an explicit defense of historical progress in his book What Technology Wants). A finitistic conception of history knows nothing of progress; we must have an infinitistic conception of history before the idea of progress can even have meaning for us. This, however, is a complex idea that requires many qualifications and therefore independent exposition. I will leave that for another day.

The Transcendental Aesthetic and the Finding of
Other Minds in Other Species
An extrapolation of the “problem of other minds” to other species
What philosophers call “the problem of other minds” is closely related to what philosophers call the “mind-body problem” (both fall within philosophy of mind), and both are paradigmatic metaphysical questions that have been with philosophy from the beginning. Lately I’ve written a good deal about the mind-body problem on my other blog (e.g., in Naturalism and the Mind, Of Distinctions Weak and Strong, Of Distinctions, Principled and Otherwise, Cartesian Formalism, etc.), and this has got me to thinking about the problem of other minds.
I have never found the idea of other minds in other species to be in the least problematic. When you look into the eyes of another living being, whether human being or other being, you are well aware of the moment of mutual recognition, and you are equally well aware at that moment of mutual recognition that you are sharing that moment with another consciousness (that is to say, you experience a social temporality).
In The Eye of the Other I wrote:
It is when we look into the eye of the other that we recognize the consciousness of the other. Even if we feel that the reality of other minds is beyond philosophical demonstration, even if we are skeptics of other minds, it would be extraordinarily difficult to look into the eyes of another and not experience that immediate reaction of recognition of another mind. When we look not only into the eyes of another being but also into the eyes of another species, there is simultaneously the recognition of the awareness of the other and of the alien nature of that awareness.
Some people feel obliged to deny this inter-species recognition of common consciousness on ideological grounds, although few ever think of speciesism as a ideology. As I have recently observed in relationship to geopolitics, which I characterized as an ideology that does not know itself to be an ideology, so too with speciesism: for many it is simply an unexamined presupposition and is never formalized as an explicit article of belief.
While I myself don’t find anything in the least problematic about consciousness in other species, and I think that anyone that takes a naturalistic point of view would be hard-pressed to deny it, I cannot deny that there are some persons who feel a real sense of moral horror in recognizing the consciousness of other species. I am fully aware of this moral horror, and I am utterly unsympathetic to it. To paraphrase Freud on the “oceanic” feeling, I am unable to discover this moral horror in myself.
Some of those who are uncomfortable with the ascription of consciousness to other species simply don’t like animals, and some of those similarly disposed are just completely uninterested in animals and find it peculiar that some human beings seem to be closer to their dogs and cats than they are to other human beings. Such persons sometimes become visibly discomfited at any mention of Johnson’s Hodge or Greyfriars Bobby or Hachikō, all memorialized by statues. I have personally heard individuals of this particular temperament indignantly lecture others (myself included) on the dangers of anthropomorphizing our companion animals. If I were to be so lectured today, I would lecture right back on anthropic bias in the philosophy of mind, which is utterly out of place and unbecoming of a philosopher (which in this instance includes anyone who makes, or who implies, philosophical assertions about mind, specifically, denying mind to certain classes of existents).
Such persons often live in an exclusively human world, and to them the animal world seems inexplicably alien. This in itself is an implicit recognition of an animal world, that is to say, a world constituted by animal consciousness. But, of course, not all who deny consciousness to other species can be so pigeon-holed. Some who have completely succumbed to anthropic bias in the philosophy of mind are in no sense living in an exclusively human world, and certainly when the dogma of human exceptionalism in consciousness gained currency, long before our industrial-technological civilization freed us from animal muscle power as the motive force of civilization, almost everyone lived intimately with animals.
In this latter context, prior to industrialization, there was always a theological overlay to the denial of consciousness to other species. Indeed, it is very likely that, if the terms of the philosophical problem of other minds were carefully explained, those with a theological world view might well without hesitation grant consciousness of other species, and simply deny they other species possess a “soul,” which is simply a theologically-legitimized devalorization. In practice, it comes to much the same as the denial of consciousness to other species and a sedulous distinction between the human and the animal realms.
I observed in The Origins of Physicalism that Cartesianism was the original “mechanical philosophy,” and while Cartesianism in the time of Descartes and immediately afterward incorporated human exceptionalism into the philosophy (i.e., it institutionalized anthropic bias in the philosophy of mind), the logical extrapolation of the theory was evident, and what the Cartesians practised upon other species later philosophers in the mechanistic tradition came to practise also upon human beings: the denial of consciousness.
Today we have a school of thought that is not exactly the denial of consciousness but rather the revaluation, or, better, the devaluation of consciousness, which latter is called a “user illusion” — at least, in techno-philosophy the denial of consciousness is called the “user illusion.” In traditional philosophy, the denial of the existence of consciousness is called “eliminativism,” since instead of seeking to reduce consciousness to something else that is not consciousness (and thereby exemplifying reductivism), eliminativism cuts the Gordian Knot and simply denies that there is any such thing as consciousness — meaning that there is nothing to be “explained away.” I am sure that I am not the only one who finds this to be a thoroughly unsatisfying “solution” to a perennial philosophical problem.
How then are we to understand the minds of other species, i.e., the problem of other minds as generalized to include non-human species? What philosophical framework exists that can provide a conceptual infrastructure for such an understanding? There are many possibilities, but today I would like to consider a Kantian approach.
If we take as the lesson of Kant’s transcendental aesthetic that the mind is being continually bombarded by a riot of sensations from all the various bodily sensory organs, and that the mind then constitutes a kind of conceptual sieve that shapes, channels and directs the mass of sensory experience into something coherent upon which an organism can act, we can recognize that much the same process occurs in other species. All mammals have more or less similar bodies and similar sensory endowments, so that all living mammals are constantly being bombarded by a riot of sensations which each creature must sort into coherent experience. The fact that we can play fetch with a dog, and both successfully interact in one and the same world, simultaneously recognizing the stick at the center of the game as an object that passes between two or more organism involved in a game of fetch, suggests that we and the dog constitute and cognize the world in a remarkably similar fashion.
The dog, like us, is receiving sensory signals from his eyes, ears, nose, and so forth, as well as experiencing kinesthetic sensations from the movement of his body as he exerts himself in lunging after the stick. From all of this sensation the dog successfully distills a world, and that world is remarkably similar to our world.
A few years ago I had an interesting experience that bears directly on games of fetch and shared experience, when I had an opportunity to feel what it was like to be a dog among dogs. I was at a vacation house on a river, and had brought my wetsuit along so I could swim. The river is fed by snow melt from Mt. Hood and it is one of the coldest rivers in which I have ever been swimming. I put on my wetsuit and got into the water just as others were beginning to play fetch with a large black lab that they had brought along. They threw a stick into the frigid waters of the river, and the lab plunged into to fetch the stick. The next time the stick was thrown I started swimming toward it the same time that the lab started swimming toward it. The lab looked at me and instantly saw me as a competitor for the stick. He swam all the harder and made it to the stick before me with an obvious sense of triumphalism.
Of course, most people have had experiences like this in life, and some people will dismiss such experiences as readily as Descartes dismissed his correspondent’s stories attempting to prove that animals are not mere mechanisms. However we interpret such experiences, we share and interact in a common world. Although this is utterly contrary to the spirit of Kant, I have to observe that any animal that could not distill coherent experience of the world out of its mass of sensation would never survive. Evolution selects for those organisms that can best hunt or avoid being prey in the common world in which predator and prey interact. This is a naturalistic point of view, whereas Kant’s point of view was decidedly that of idealism.
Even if one rejects Kant’s idealism, as I do, there seems to me to be some residual value in the idea of the mind being involved in the constitution of experience. I think that Kant was right that we have certain a priori intuitions that order our experience, but I think that this was much more fluid and pluralistic than Kant’s exposition of the transcendental aesthetic allows. While I wrote above that mammals all have a relatively similarly experience of the world, a function of a similar sensory and cognitive endowments, I would allow that there is some important variation. Sight plays a very large role in how human beings cognize the world; smell plays a disproportionate role in how dogs cognize the world; sound plays a disproportionate role in how dolphins cognize the world.
All terrestrial critters of a given level of cognitive complexity have to distill coherent experience of one and the same world out of a mass of sensation, but that mass of sensation differs among different species. I suspect that this sensory difference means that different species also have different a priori conceptions that help them to organize their experience into a coherent whole, and that, just sensory experience differs from species to species, but admits of degrees of greater or less, so too the a priori ideas of distinct species different from species to species but also admit of greater or less similarity. That is to say, smell may shape the world of a dog far more than it shapes our world, but we probably share far more in terms of sensory experience and organizing ideas with a dog than with a marine mammal, and probably we share much more with a marine mammal than with an octopus or other cephalopod. This is a function and an illustration of a point I recently tried to make about the relationship between mind and embodiment.
I tried to make this point in my above referenced post, The Eye of the Other, since when I unexpectedly looked into the eyes of a sealion, a marine mammal, we immediately recognized each other, and in the same moment of recognition also recognized the profound differences between the two of us. Common mammalian minds, differently embodied and living in profoundly different environments, will involve different sensory stimulation, different kinesthetic sensations, and different a priori concepts for organizing experience. But not too different. A shark, with a mind very different from a mammalian mind, can predate marine mammals, so that both sharks and marine mammals interact in the same marine environment just as human beings and tigers interact in the same terrestrial environment.
I suspect that, at least in some senses, the tiger’s mind and the human mind share concepts derived from their common terrestrial environment, while the shark and the marine mammal share concepts derived from the common marine environment, so that a tiger’s mind is more like a human mind than a sea lion’s mind is like a human mind, and, vice versa, a sea lion’s mind is more like a shark’s mind than it is like a human mind. Nevertheless, the human mind and the sea lion mind will share some concepts due to their common mammalian constitution. To employ a Wittgensteinian turn of phrase, the different sensations, concepts, and minds of distinct species overlap and intersect.
The recognition of consciousness in other species is no marginal and recondite inquiry; if, in the fullness of time, we encounter other intelligent species in the universe of extraterrestrial origin, we will need a philosophical framework in which we can integrate the idea of consciousness among other organic species, and if research into artificial intelligence and machine consciousness ever issues in a self-aware mechanism, fashioned by human hands in the same way that we might build a car or a house, we will again require a philosophical framework in which we can integrate the idea of consciousness even more generally, comprehending both naturally-emergent consciousness from organic substrates and artificially emergent consciousness of non-organic substrates.
We need a robust philosophy of mind that does not stagnate in questions of whether there is mind or whether minds can be reduced to other phenomena or eliminated altogether. Such doctrines are — would be — utterly unhelpful in coming to understand what Husserl called the “structures of consciousness.” It is likely that the structures of consciousness vary incrementally among individuals of the same species, vary a little more across distinct species, and will vary even more among minds derived from different sources — different ecosystems and biospheres in the case of organically-originating extraterrestrial minds, and different mechanisms of implementation in the case of inorganically-originating minds of machine consciousness.

2 March 2013
Arthur C. Clarke is best remembered for this science fiction stories, but many of his dicta and aphorisms have become common currency and are quoted and repeated to the point that their connection to their source is sometimes lost. (Clarke’s thought ranged widely and, interestingly, Clarke identified himself as a logical positivist.) Recently I quoted one of Clarke’s well-known sayings in Happy Birthday Nicolaus Copernicus!, as follows:
“Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.”
quoted in Visions: How Science Will Revolutionize the Twenty-First Century (1999) by Michio Kaku, p. 295
In so saying, Clarke asserted a particular case of what is known as the logical law (or principle) of the excluded middle, which is also known as tertium non datur: the idea that, given a proposition and its negation, either one or the other of them must be true. This is also expressed in propositional logic as “P or not-P” (“P v ~P”). The principle of tertium non datur is not to be confused with the principle of non-contradiction, which can be formulated as “~(P & ~P).”
Even stating tertium non datur is controversial, because there are narrowly logical formulations as well as ontological formulations of potentially much greater breadth. This, of course, is what makes the principle fascinating and gives it its philosophical depth. Moreover, the principle of the excluded middle is subtly distinct from the principle of bivalence, though the two usually work in conjunction. Whereas the law of the excluded middle states that of a proposition and its negation, one of the other must be true, the principle of bivalence states that there are only two propositional truth values: true and false.
To get started, here is the principle of the excluded middle as formulated in The Cambridge Dictionary of Philosophy edited by Robert Audi:
principle of excluded middle, the principle that the disjunction of any (significant) statement with its negation is always true; e.g., ‘Either there is a tree over 500 feet tall or it is not the case that there is such a tree’. The principle is often confused with the principle of bivalence.
THE CAMBRIDGE DICTIONARY OF PHILOSOPHY second edition, General Editor Robert Audi, 1999, p. 738
And to continue the Oxbridge axis, here is the formulation from Simon Blackburn’s The Oxford Dictionary of Philosophy:
excluded middle, principle (or law) of The logical law asserting that either p or not-p. It excludes middle cases such as propositions being half correct or more or less right. The principle directly asserting that each proposition is either true or false is properly called the law of bivalence.
The Oxford Dictionary of Philosophy, Simon Blackburn, Oxford University Press, 1996, p. 129
For more partisan formulations, we turn to other sources. Mario Bunge formulated a narrowly syntactical conception of the law of the excluded middle in his Dictionary of Philosophy, which is intended to embody a scientistic approach to philosophy:
EXCLUDED MIDDLE A logical truth or tautology in ordinary (classical) logic: For every proposition p, p v ~p.
Dictionary of Philosophy, Mario Bunge, Prometheus Books, 1999, p. 89
By way of contrast, in D. Q. McInerny’s Being Logical: A Guide to Good Thinking we find a strikingly ontological formulation of the law of the excluded middle:
“Between being and nonbeing there is no middle state. Something either exists or it does not exist; there is no halfway point between the two.”
D. Q. McInerny, Being Logical: A Guide to Good Thinking, Part Two, The Basic Principles of Logic, 1. First Principles, p. 26
What these diverse formulations bring out for us is the difficulty of separating logical laws of how formal systems are to be constructed from ontological laws about how the world is constructed, and in so bringing out this difficulty, they show us the relation between the law of the excluded middle and the principle of bivalence, since the logical intuition that there are only two possible truth values of any one proposition — true or false — is so closely tied to our logical intuition that, of these two values, one or the other (but not both, which qualification is the principle of non-contradiction) must hold for any given (meaningful) proposition.
The powerful thing about Clarke’s observation is that it appeals to this admixture of logical intuitions and empirical intuitions, and in so doing seems to say something very compelling. Indeed, since I am myself a realist, and I think it can be shown that there is a fact of the matter that makes propositions true or false, I think that Clarke not only said something powerful, he also said something true: either there are extraterrestrial intelligences or there are not. It is humbling to contemplate either possibility: ourselves utterly alone in a vast universe with no other intelligent species or civilizations, or some other alien intelligence out there somewhere, unknown to us at present, but waiting to be discovered — or to discover us.
Although these logical intuitions are powerful, and have shaped human thought from its earliest times to the present day, the law of the excluded middle has not gone unquestioned, and indeed Clarke’s formulation gives us a wonderful opportunity to explore the consequences of the difference between constructive and non-constructive reasoning in terms of a concrete example.
To formulate the existence or non-existence of extraterrestrials in the form of a logical law like the law of the excluded middle makes the implicit realism of Clarke’s formulation obvious as soon as we think of it in these terms. In imagining the possibilities of our cosmic isolation or an unknown alien presence our terror rests on our intuitive, visceral feeling of realism, which is as immediate to us as the intuitions rooted in our own experiences as bodies.
The constructivist (at least, most species of constructivist, but not necessarily all) must deny the validity of the teritum non datur formulation of the presence of extraterrestrials, and in so doing the constructivist must pretend that our visceral feelings of realism are misleading or false, or must simply deny that these feelings exist. None of these are encouraging strategies, especially if one is committed to understanding the world by getting to the bottom of things rather than denying that they exist. Not only I am a realist, but I also believe strongly in the attempt to do justice to our intuitions, something that I have described in two related posts, Doing Justice to Our Intuitions and How to Formulate a Philosophical Argument on Gut Instinct.
In P or not-P (as well as in subsequent posts concerned with constructivism, What is the relationship between constructive and non-constructive mathematics? Intuitively Clear Slippery Concepts, and Kantian Non-constructivism) I surveyed constructivist and non-constructivist views of tertium non datur and suggested that constructivists and non-constructivists need each other, as each represents a distinct point of view on formal thought. Formal thought is enriched by these diverse perspectives.
But whereas non-constructive thought, which is largely comprised of classical realism, can accept both the constructivist and non-constructivist point of view, the many varieties of constructivism usually explicitly deny the validity of non-constructive methods and seek to systematically limit themselves to constructive methods and constructive principles. Most famously, L. E. J. Brouwer (whom I have previously discussed in Saying, Showing, Constructing and One Hundred Years of Intuitionism and Formalism) formulated the philosophy of mathematics we now know as intuitionism, which is predicated upon the explicit denial of the law of the excluded middle. Brouwer, and those following him such as Heyting, sought to formulate mathematical and logic reasoning without the use of tertium non datur.
Brouwer and the intuitionists (at least as I interpret them) were primarily concerned to combat the growing influence of Cantor and his set theory in mathematics, which seemed to them to license forms of mathematical reasoning that had gone off the rails. Cantor had gone too far, and the intuitionists wanted to reign him in. They were concerned about making judgments about infinite totalities (in this case, sets with an infinite number of members), which the law of the excluded middle, when applied to the infinite, allows one to do. This seems to give us the power to make deductions about matters we cannot either conceive or even (as it is sometimes said) survey. “Surveyability” became a buzz word in the philosophy of mathematics after Wittgenstein began using it in his posthumously published Remarks on the Foundations of Mathematics. Although Wittgenstein was not himself an intuitionist sensu stricto, his work set the tone for constructivist philosophy of mathematics.
Given the intuitionist rejection of the law of the excluded middle, it is not correct to say that there either is intelligent alien life in the universe or there is not intelligent alien life in the universe; to meaningfully make this statement, one would need to actually observe (inspect, survey) all possible locations where such alien intelligence might reside, and only after seeing it for oneself can one legitimately claim that there is or is not alien intelligence in the universe. For am example closer to home, it has been said that an intuitionist will deny the truth of the statement “either it is raining or it is not raining” without looking out the window to check and see. This can strike one as merely perverse, but we must take the position seriously, as I will try to show with the next example.
Already in classical antiquity, Aristotle brought out a striking feature of the law of the excluded middle, in a puzzle sometimes known as the “sea battle tomorrow.” The idea is simple: either there will be a sea battle tomorrow, or there will not be a sea battle tomorrow. We may not know anything about this battle, and as of today we do not even know if it will take place, but we can nevertheless confidently assert that either it will take place or it will not take place. This is the law of the excluded middle as applied to future contingents.
One way to think of this odd consequence of the law of the excluded middle is that when it is projected beyond the immediate circumstances of our ability to ascertain its truth by observation it becomes problematic. This is why the intuitionists reject it. Aristotle extrapolated the law of the excluded middle to the future, but we could just as well extrapolate it into the past. Historians do this all the time (either Alexander cut the Gordian Knot or Alexander did not cut the Gordian Knot), but because of our strong intuitive sense of historical realism this does not feel as odd as asserting that something that hasn’t happened yet either will happen or will not happen.
In terms of Clarke’s dichotomy, we could reformulate Aristotle’s puzzle about the sea battle tomorrow in terms of the discovery of alien intelligence tomorrow: either we will receive an alien radio broadcast tomorrow, or we will not receive an alien broadcast tomorrow. There is no third possibility. One way or another, the realist says, one of these propositions is true, and one of them is false. We do not know, today, which one of them is true and which one of them is false, but that does not mean that they do no possess definite truth values. The intuitionist says that the assertion today that we will or will not receive an alien radio broadcast is meaningless until tomorrow comes and we turn on our radio receivers to listen.
The intuitionists thus have an answer to this puzzling paradox that remains a problem for the realist. This is definitely a philosophical virtue for intuitionism, but, like all virtues, it comes at a price. It is not a price I am willing to pay. This path can also lead us to determinism — assuming that all future contingents have a definite truth value implies that they are set in stone — but I am also not a determinist (as I discussed in The Denial of Freedom as a Philosophical Problem), and so this intersection of my realism with my libertarian free willist orientation leaves me with a problem that I am not yet prepared to resolve. But that’s what makes life interesting.

Morally Distinguishable Outcomes in
Global Catastrophic Scenarios
Below is Nick Bostrom’s table of qualitative categories of risk. Bostrom and Milan M. Ćirković have together edited a book on Global Catastrophic Risks, which includes this table. Existential risks, that is to say, risk that could result in human extinction, are identified as “an especially severe subset” of global catastrophic risks.
Of existential risks and their potential consequences I recently wrote this:
“When we think about what this means for us, our other ‘priorities’ pale by comparison. Nothing else matters, no matter how apparently pressing, if we are made extinct by an accident of local cosmology.”
Thinking of this further, I realized that there are many ethical presuppositions implicit in my formulation, and that (at least some of) these presuppositions can be spelled out and made explicit.
Bostrom’s table of qualitative risk categories suggest possibilities of scope and intensity beyond those comprised by global catastrophic risk and existential risk, and on the margin of the table we see “Cosmic?” as a possible scope beyond “pan-generational” and “Hellish?” as a potential intensity beyond “Terminal.” Thus what is cosmic and hellish is a qualitative risk category beyond even that of existential risk. I think that there are moral intuitions from catastrophic outcomes that correspond to these almost unthinkable scenarios.
While it would seem that there is little worse that could happen (from a human perspective, i.e., fully informed by anthropic bias) than human extinction, even given our anthropic bias and therefore our desire to avoid human extinction there are morally distinguishable outcomes in many different scenarios of global catastrophe and human extinction, and where there is the possibility of morally distinguishable outcomes there also will be the possibility of ranking these moral outcomes from the least awful possibility to the worst of all possibilities. There is also the likelihood of moral disagreements on these rankings, and these moral disagreements over prioritizing existential risk mitigation could prove crucial in future debates over the allocation of civilizational resources to existential risk mitigation. Thus even if existential risk comes to be seen as an overriding priority for human beings and civilization, this is not yet the convergence of human moral effort; room for profound disagreement yet remains.
Considering a range of devastating and catastrophic events that could compromise human life and human civilization, possibly to the point of their extinction, I can think of six scenarios in order of severity:
1. Massive but survivable catastrophe A global catastrophic risk realized that results in the loss of millions or billions of lives and deals a major setback to civilization, without either extinguishing human beings or human civilization (in Bostrom’s table of qualitative risks these would include global, trans-generational, and pan-generational endurable risks).
2. Catastrophic failure of civilization A global catastrophic risk realized that resulted in the catastrophic failure of civilization, but does not result in the extinction of human beings. The human population might be drastically reduced to paleolithic population levels, but potentially could rebound. There remains the possibility that civilization might be reconstituted, but this is likely to take hundreds if not thousands of years. (“Global dark age” in the table above.)
3. Human extinction The first level of human extinction I will call simple extinction, which is an existential risk realized, which however leaves the Earth intact, and the legacy of human civilization intact. I add this latter qualification because it is possible, even if human beings become extinct, that human civilization might leave monuments that could be appreciated by other sentient species that could visit the Earth. It is even possible (however unlikely) that other species might appreciate the human record of civilization more than we appreciate it ourselves. Thus human extinction need not mean the loss of human cultural legacy. A pandemic that killed only human beings could have this result. (X marks the spot in the table above.)
4. Human extinction with the extirpation of all human legacy The second level of human extinction I will call compound extinction, which is an existential risk realized that results in human extinction and the elimination of all (or almost all) signs of human presence, but which leaves the biosphere largely intact, and the ordinary business of terrestrial life continues largely unchanged. (This is human extinction coupled with “destruction of cultural heritage.”)
5. Catastrophic compromise of the biosphere The third level of human extinction involves not only the extinction of human beings and all human legacy, but also the extinction of all complex life on the Earth. Terrestrial life continues, but is reduced to single celled organisms. Thus there remains the possibility that life on Earth may recover, but this would probably require billions of years and result in very different life forms.
6. Terrestrial sterilization The most radical form of realized existential risk is terrestrial sterilization which results in human extinction, the extirpation of all human legacy, and the elimination of all terrestrial life, i.e., complete catastrophic failure of the biosphere. From this point there is nothing that can be recovered and no human legacy remains.
I tried to arrange these various morally distinct outcomes on an expanded version of Bostrom’s table of qualitative risk categories, but couldn’t yet find a conceptually neat and straight-forward way to do so. Further thought is needed here. I don’t think there is a need to distinguish further qualitative categories of risk beyond existential risk — in other words, we can refer to all of these morally distinct outcomes as outcomes of existential risk, as realized in distinct scenarios. However, one could make such distinctions if it were helpful to do so.
The most radical moral imperative of existential risk is to take existential risk as absolute and as trumping all other concerns, which is what I clearly implied when I wrote that, “…our other ‘priorities’ pale by comparison. Nothing else matters, no matter how apparently pressing…” if we are made (or make ourselves) extinct. This radical position has profound and discomfiting implications.
If we survey the evils of the world, we would be forced to acknowledge that it is better that any or all of these evils continue than that human life should be permanently extinguished, because the continuation of these evils is consistent with the continuation of human life and human civilization. The end of all human life would also mean the end of all the cruelties and inhumanity that we inflict upon our fellow man, and this would be a good and indeed a desirable state of affairs, but from a radical perspective on existential risk we would have to affirm that, as good a state of affairs as this represents, it would not be as morally good as the state of affairs that involves the perpetuation of these evils together with the perpetuation of human life and civilization.
Of course, under most conceivable scenarios there is no reason whatsoever to suppose that we had to choose between the perpetuation of all the evils of the world and human extinction. That is to say, there is no reason that we cannot work toward the elimination of human evils and the mitigation of existential risks. As a moral thought experiment, however, we can employ the method of isolation and ask whether the survival of human beings and human civilization, together with all the evils this entails is better than the annihilation of human beings and human civilization, so that neither human good nor human evil remains.
While I would be willing to assert that existential risk mitigation trumps all other concerns, even in a thought experiment in which human evils remain unmitigated, I can easily imagine that there are many who would disagree with this judgment. Moral diversity is a fact of human life, and we must recognize that if some among us (myself included) would be willing to explicitly affirm the radical moral consequences of prioritizing existential risk mitigation, there will be others who will equally explicitly reject a radical prioritization of existential risk mitigation, and who will affirm that it is better that the world should come to an end than that the manifold evils of our time should persist. From this point of view, in view of the limited resources available to human beings, we would do better to direct these resources to the mitigation of human evils than to direct these resources to the mitigation of existential risk.
It is entirely possible that someone might affirm that it is a good thing civilization should be ended, and the idea has incredible romantic appeal that cannot be denied and should not be ignored. Many are the science fiction books and films (for example, think of Logan’s Run or 12 Monkeys) that depict a world empty of human beings and populated only by collapsing buildings and animals hunting in the ruins. This scenario is depicted, for example, in Alan Weisman’s book The World Without Us.
The idea that civilization is evil can easily be extended to the idea that humanity is evil in and of itself. The predictions of the original Club of Rome report of 1972, The Limits to Growth, have been widely discussed on its recent 40th anniversary, but what has not been remarked is the language and tone of that original document (which you will not find on the internet, despite the millions of used copies kicking around). The report boldly asserted, “The earth has cancer and the cancer is Man.” This kind of rhetoric, which is less common today, can easily play into a principled denial of the moral value of humanity.
And it is easy to understand why. The world is filled with evils, and the most horrific evils are those that human beings perpetrate upon other human beings — homo homini lupus. If we prioritize existential risk mitigation over the mitigation of human evils, we find ourselves forced into the uncomfortable position of tolerating Kantian radical evil, Marilyn McCord Adams’ conception of horrendous evils, and Claudia Card’s atrocities. Imagine the horrors of genocide, torture, and industrialized warfare and then imagine being forced to admit that it is better than genocides occur, better that torture continues, and better that industrialized warfare persists than that an existential risk be realized. This is a hard saying; nevertheless, this is the argument that must be made, and it is always best to face a hard argument directly than to attempt to avoid it.
In Marilyn McCord Adams’ exposition of what she calls “horrendous evils” in her book Horrendous Evils and the Goodness of God Adams wrote:
“Among the evils that infect this world, some are worse than others. I want to try to capture the most pernicious of them within the category of horrendous evils, which I define (for present purposes) as ‘evils the participation in which (that is, the doing or suffering of which) constitutes prima facie reason to doubt whether the participant’s life could (given their inclusion in it) be a great good to him/her on the whole.’ The class of paradigm horrors includes both individual and massive collective suffering…”
Marilyn McCord Adams, Horrendous Evils and the Goodness of God, Ithica: Cornell University Press, 1999, p. 26.
She went on to add in the next section:
“I believe most people would agree that such evils as listed above constitute reason to doubt whether the participants’ life can be world living, because it is so difficult humanly to conceive how such evils could be overcome.”
In the last paragraph of her paper of the same title, Adams again suggests that horrendous evils call into question the possibility of having a life worth living:
“I would go one step further: assuming the pragmatic and/or moral (I would prefer to say, broadly speaking, religious) importance of believing that (one’s own) human life is worth living, the ability of Christianity to exhibit how this could be so despite human vulnerability to horrendous evil, constitutes a pragmatic/moral/religious consideration in its favour, relative to value schemes that do not.”
Marilyn McCord Adams, “Horrendous Evils and the Goodness of God.” Anthologized in The Problem of Evil, edited by Marilyn McCord Adams and Robert Merrihew Adams, Oxford: Oxford University Press, 1990, p. 221.
A generalization of Adams’ argument could easily bring us from the point where horrendous evils make the individual doubt or question that one’s life is worth living to the point where humanity on the whole legitimately, and on principle, questions whether any human life at all is worth living. If humanity comes to decide that horrendous evils overwhelm all value in the world and make human existence utterly meaningless and pointless, then the mitigation of existential risk can come to seem like an evil or an impiety.
Adams finds her answer to this in Christianity; we naturalists cannot appeal to supernaturalistic validation or justification: we must take human evil on its face along with human good, and if we prioritize the mitigation of existential risk (and therefore the continuity of humanity and human civilization), we do so knowing that human evils will continue and are probably ineradicable if not inseparable from human history.
We can actively seek to mitigate human evils, and the effort has intrinsic value, but the intrinsic value of the mitigation of suffering and mundane meliorism can only continue in the case that humanity and organized human activity continue. Therefore the prioritization of the mitigation of existential risk is what makes possible the realization of the intrinsic value of the mitigation of suffering and efforts toward meliorism. With the end of humanity would also come not only an end to all intrinsic goods of human life, but also an end to the intrinsic good of the mitigation of suffering and the effort to make the world a better place.
We can only create a better civilization if civilization continues. If we are perfectibilists, we may believe in the perfectibility of man and indeed even the perfectibility of civilization. This project cannot even be undertaken if humanity and human civilization are cut short in their imperfect state.

22 February 2013
Much of what I write here, whether commenting on current affairs to delving into the depths of prehistory, could be classed under the general rubric of philosophy of history. One of my early posts to this forum was Of What Use is Philosophy of History in Our Time? (An echo of the title of Hans Meyerhoff’s widely available anthology Philosophy of History in Our Time.) It could be argued that my subsequent posts have been attempts to answer this question (that is to say, to answer the question what is the use of philosophy of history in our time), to demonstrate the usefulness of bringing a philosophical perspective to history, contemporary and otherwise. The reader is left to judge whether this attempt has been a success (partial or otherwise) or a failure (partial or otherwise).
In several recent posts — as, for example in The Science of Time, Addendum on Big History as the Science of Time, and Human Agency and the Exaptation of Selection, inter alia — I have been writing a lot about the philosophy of history from the perspective of big history, which is a contemporary historiographical school that comes to history from the perspective of the big picture and primarily proceeds according to scientific naturalism. This latter condition makes of big history a particular species of naturalism.
In many posts to this forum I have emphasized my own naturalistic perspective both in philosophy generally speaking as well as more specifically in the philosophy of history. For example, in posts such as Natural History and Human History, The Continuity of Civilization and Natural History, and An Existentialist Philosophy of History, I have emphasized the continuity of human history and natural history, especially making the attempt to place civilization in a natural historical context.
This emphasis on big history and naturalism has meant that I have spent very little time writing about alternatives to naturalistic historical thought — with a certain exception, which the reader may well not immediately recognize, so I will point it out explicitly. In several posts — The Ethos of Formal Thought, Foucault’s Formalism, Cartesian Formalism, and Formal Strategy and Philosophical Logic: Work in Progress among them — I have discussed the possibility of formal thought in relation to historical understanding, i.e., topics not usually discussed from a formal perspective (which is usually confined to logic, mathematics, and some branches of science). Formalism represents a certain kind of countervailing intellectual influence to naturalism, and it has probably served roughly that function in my thought.
I have previously mentioned Darren Staloff’s lectures on the philosophy of history, The Search for a Meaningful Past: Philosophies, Theories and Interpretations of Human History. One of the motifs running through Staloff’s lectures is a contrast between what he calls naturalism and idealism. He sums up this motif in the final lecture, in which he adopts the perspectives of naturalism and idealism in turn, trying give the listener a sense of the claims of each tradition. I found Staloff’s exposition of idealism less persuasive that his exposition of naturalism, and so I found the motif of a contrast between naturalism and idealism a bit strained, since it seemed to me that idealism really couldn’t carry its own weight in the way that it might have been able to in the past.
Recently I’ve encountered an approach to the philosophy of history that could be called “idealist” (at least in a certain sense), and this is much more persuasive to me that Staloff’s analytical representatives of the idealist tradition, like R. G. Collingwood. I have found this idealist perspective in the work of Ludwig Landgrebe, who was one of Husserl’s research assistants.
The casual reader of this blog might well have picked up on the amount of contemporary continental philosophy that I have read, but it unlikely to have realized the extent to which Edmund Husserl and phenomenology have been an influence on my thought. Nevertheless, that influence has been profound, to the point that many of Husserl’s expositors and commentators have also influenced my thinking. Recently I have been reading some essays by Ludwig Landgrebe, and this has started to give me another perspective on the philosophy of history.
Landgrebe wrote at least two papers on the philosophy of history, as well as one chapter of his book, Major Problems in Contemporary European Philosophy, from Dilthey to Heidegger. No doubt there is more material, but this is what I have found translated into English. (Landgrebe wrote an entire book on the phenomenological philosophy of history, Phänomenologie und Geschichte, but this has not been translated into English.) The two papers are “Phenomenology as Transcendental Theory of History” (which can be found in the collection of essays Husserl: Expositions and Appraisals, edited by Elliston and McCormick, University of Notre Dame Press, 1977. pp. 101-113) and “A Meditation on Husserl’s Statement: ‘History is the grand fact of absolute Being’” (The Southwestern Journal of Philosophy, Vol. 5, Issue 3, Fall 1974, pp. 111-125).
It is well known that Husserl’s last work, The Crisis of European Sciences and Transcendental Phenomenology: An Introduction to Phenomenological Philosophy, assembled posthumously from his papers, is the work in which Husserl placed phenomenology in historical context (for all practical purposes, for the first time), and considered the emergence of Western scientific thought in historical context. As such, this has been the point of departure of much historically-oriented phenomenological research, and the Crisis (as it has come to be known) and its supplementary texts were clearly influential for Landgrebe.
Landgrebe, however, as Husserl’s research assistant, was more than conversant with Husserl’s logical thought also. Husserl’s Experience and Judgment: Investigations in a Genealogy of Logic was a text assembled by Landgrebe from Husserl’s notes. Landgrebe consulted with Husserl throughout this project, and the original texts are all due to Husserl, but the structure of the book is entirely Landgrebe’s doing. Landgrebe brings the kind of rigor one learns in studying logic to his very compact essays on the philosophy of history. In this way, Landgrebe’s formulations have a formal character that makes them very congenial to me. Landgrebe’s approach is essentially that of a formal phenomenological theory of history, and this perspective allows me to assimilate Landgrebe’s insights both to idealistic historiography as well as my long-standing interest in formal thought.
If I were now to revise my speculative syllabus If I Lectured on the Philosophy of History (lecture 13 of which I had already assigned to phenomenology), I would definitely showcase Landgrebe’s philosophy of history as the most sophisticated phenomenological contribution to the philosophy of history.

F. H. Bradley in his classic treatise Appearance and Reality: A Metaphysical Essay, made this oft-quoted comment:
“If you identify the Absolute with God, that is not the God of religion. If again you separate them, God becomes a finite factor in the Whole. And the effort of religion is to put an end to, and break down, this relation — a relation which, none the less, it essentially presupposes. Hence, short of the Absolute, God cannot rest, and, having reached that goal, he is lost and religion with him. It is this difficulty which appears in the problem of the religious self-consciousness.”
I think many commentators have taken this passage as emblematic of what they believe to be Bradley’s religious sentimentalism, and in fact the yearning for religious belief (no longer possible for rational men) that characterized much of the school of thought that we now call “British Idealism.”
This is not my interpretation. I’ve read enough Bradley to know that he was no sentimentalist, and while his philosophy diverges radically from contemporary philosophy, he was committed to a philosophical, and not a religious, point of view.
Bradley was an elder contemporary of Bertrand Russell, and Bertrand Russell characterized Bradley as the grand old man of British idealism. This if from Russell’s Our Knowledge of the External World:
“The nature of the philosophy embodied in the classical tradition may be made clearer by taking a particular exponent as an illustration. For this purpose, let us consider for a moment the doctrines of Mr Bradley, who is probably the most distinguished living representative of this school. Mr Bradley’s Appearance and Reality is a book consisting of two parts, the first called Appearance, the second Reality. The first part examines and condemns almost all that makes up our everyday world: things and qualities, relations, space and time, change, causation, activity, the self. All these, though in some sense facts which qualify reality, are not real as they appear. What is real is one single, indivisible, timeless whole, called the Absolute, which is in some sense spiritual, but does not consist of souls, or of thought and will as we know them. And all this is established by abstract logical reasoning professing to find self-contradictions in the categories condemned as mere appearance, and to leave no tenable alternative to the kind of Absolute which is finally affirmed to be real.”
Bertrand Russell, Our Knowledge of the External World, Chapter I, “Current Tendencies”
Although Russell rejected what he called the classical tradition, and distinguished himself in contributing to the origins of a new philosophical school that would come (in time) to be called analytical philosophy, the influence of figures like F. H. Bradley and J. M. E. McTaggart (whom Russell knew personally) can still be found in Russell’s philosophy.
In fact, the above quote from F. H. Bradley — especially the portion most quoted, short of the Absolute, God cannot rest, and, having reached that goal, he is lost and religion with him — is a perfect illustration of a principle found in Russell, and something on which I have quoted Russell many times, as it has been a significant influence on my own thinking.
I have come to refer to this principle as Russell’s generalization imperative. Russell didn’t call it this (the terminology is mine), and he didn’t in fact give any name at all to the principle, but he implicitly employs this principle throughout his philosophical method. Here is how Russell himself formulated the imperative (which I last quoted in The Genealogy of the Technium):
“It is a principle, in all formal reasoning, to generalize to the utmost, since we thereby secure that a given process of deduction shall have more widely applicable results…”
Bertrand Russell, An Introduction to Mathematical Philosophy, Chapter XVIII, “Mathematics and Logic”
One of the distinctive features that Russell identifies as constitutive of the classical tradition, and in fact one of the few explicit commonalities between the classical tradition and Russell’s own thought, was the denial of time. The British idealists denied the reality of time outright, in the best Platonic tradition; Russell did not deny the reality of time, but he was explicit about not taking time too seriously.
Despite Russell’s hostility to mysticism as expressed in his famous essay “Mysticism and Logic,” when it comes to the mystic’s denial of time, Russell softens a bit and shows his sympathy for this particular aspect of mysticism:
“Past and future must be acknowledged to be as real as the present, and a certain emancipation from slavery to time is essential to philosophic thought. The importance of time is rather practical than theoretical, rather in relation to our desires than in relation to truth. A truer image of the world, I think, is obtained by picturing things as entering into the stream of time from an eternal world outside, than from a view which regards time as the devouring tyrant of all that is. Both in thought and in feeling, even though time be real, to realise the unimportance of time is the gate of wisdom.”
“…impartiality of contemplation is, in the intellectual sphere, that very same virtue of disinterestedness which, in the sphere of action, appears as justice and unselfishness. Whoever wishes to see the world truly, to rise in thought above the tyranny of practical desires, must learn to overcome the difference of attitude towards past and future, and to survey the whole stream of time in one comprehensive vision.”
Bertrand Russell, Mysticism and Logic, and Other Essays, Chapter I, “Mysticism and Logic”
While Russell and the classical tradition in philosophy both perpetuated the devalorization of time, this attitude is slowly disappearing from philosophy, and contemporary philosophers are more and more treating time as another reality to be given philosophical exposition rather than denying its reality. I regard this as a salutary development and a riposte to all who claim that philosophy makes no advances. Contemporary philosophy of time is quite sophisticated, and embodies a much more honest attitude to the world than the denial of time. (For those looking at philosophy from the outside, the denial of the reality of time simply sounds like a perverse waste of time, but I won’t go into that here.)
In any case, we can bring Russell’s generalization imperative to time and history even if Russell himself did not do so. That is to say, we ought to generalize to the utmost in our conception of time, and if we do so, we come to a
principle parallel to Bradley’s that I think both Russell and Bradley would have endorsed: short of the absolute time cannot rest, and, having reached that goal, time is lost and history with it.
Since I don’t agree with this, but it would be one logical extrapolation of Russell’s generalization imperative as applied to time, this suggests to be that there is more than one way to generalize about time. One way would be the kind of generalization that I formulated above, presumably consistent with Russell’s and Bradley’s devalorization of time. Time generalized in this way becomes a whole, a totality, that ceases to possess the distinctive properties of time as we experience it.
The other way to generalize time is, I think, in accord with the spirit of Big History: here Russell’s generalization imperative takes the form of embedding all times within larger, more comprehensive times, until we reach the time of the entire universe (or beyond). The science of time, as it is emerging today, demands that we almost seek the most comprehensive temporal perspective, placing human action in evolutionary context, placing evolution in biological context, placing biology is in geomorphological context, placing terrestrial geomorphology into a planetary context, and placing this planetary perspective into a cosmological context. This, too, is a kind of generalization, and a generalization that fully feels the imperative that to stop at any particular “level” of time (which I have elsewhere called ecological temporality) is arbitrary.
On my other blog I’ve written several posts related directly or obliquely to Big History as I try to define my own approach to this emerging school of historiography: The Place of Bilateral Symmetry in the History of Life, The Archaeology of Cosmology, and The Stars Down to Earth.
The more we pursue the rapidly growing body of knowledge revealed by scientific historiography, the more we find that we are part of the larger universe; our connections to the world expand as we pursue them outward in pursuit of Russell’s generalization imperative. I think it was Hans Blumenberg in his enormous book The Genesis of the Copernican World, who remarked on the significance of the fact that we can stand with our feet on the earth and look up at the stars. As I remarked in The Archaeology of Cosmology, we now find that by digging into the earth we can reveal past events of cosmological history. As a celestial counterpart to this digging in the earth (almost as though concretely embodying the contrast to which Blumenberg referred), we know that by looking up at the stars, we are also looking back in time, because the light that comes to us ages after it has been produced. Thus is astronomy a kind of luminous archaeology.
In Geometrical Intuition and Epistemic Space I wrote, “…we have no science of time. We have science-like measurements of time, and time as a concept in scientific theories, but no scientific theory of time as such.” Scientists have tried to think scientifically about time, but, as with the case of consciousness, a science of time eludes us as a science of consciousness eludes us. Here a philosophical perspective remains necessary because there are so many open questions and no clear indication of how these questions are to be answered in a clearly scientific spirit.
Therefore I think it is too early to say exactly what Big History is, because we aren’t logically or intellectually prepared to say exactly what the Russellian generalization imperative yields when applied to time and history. I think that we are approaching a point at which we can clarify our concepts of time and history, but we aren’t quite there yet, and a lot of conceptual work is necessary before we can produce a definitive formulation of time and history that will make of Big History the science and it aspires to be.

Learning to Love the Wisdom
of Industrial-Technological Civilization
A confession of enthusiasm
Allow me to give free rein to my enthusiasm and to proclaim that there has never been a more exciting time in human history to be a philosopher than today. It is ironic that, at the same time, philosophers are probably held in lower esteem today than in any other period of human history. I have recently come to the opinion that it is intrinsic to the structure of industrial-technological civilization to devalue philosophy, but I have discussed the contemporary neglect of philosophy in several posts — Fashionable Anti-Philosophy, Further Fashionable Anti-Philosophy, and Beyond Anti-Philosophy among them — so that is not what I am going to write about today.
Today, on the contrary, I want to write about the great prospects that are now opening up to philosophy, despite its neglect in popular culture and its abuse by the enthusiasts of a positivistically-conceived science. And these prospects are not one but many. In some previous posts about object-oriented philosophy (also called object-oriented ontology, or OOO) I mentioned how exciting it was to be alive at a time when a new philosophical school was coming into being, especially at a time when academic philosophy seems to have stalled and relinquished any engagement with the world or any robust relationship to the ordinary lives of ordinary human beings. (As bitterly as the existentialists were denounced in their day, they did engage quite directly with contemporary events and contemporary life. Sartre made a fool of himself by meeting with Che Guevara and by mouthing Maoist claptrap in his later years, but he reached far more people than most philosophers of his generation, and like fellow existentialist Camus, did so through a variety of prose works, plays, and novels.) Now I see that we live in an age of the emergence of not one but of many different philosophical schools, and this is interesting indeed.
Philosophical periodization: schools of thought
Anyone who discusses so-called “schools” in philosophy is likely to run into immediate resistance, usually from those who have been characterized as belonging to a dubiously-conceived school. As soon as Sartre gave an explicit definition of existentialism as being based on the principle that existence precedes essence, Heidegger and Jaspers explicitly and emphatically denied that they were “existentialists.” And if we think of the hundreds years of philosophical research and the hundreds of philosophers who can be lumped under the label of “scholasticism,” the identification of a school of “scholastic” philosophers would seem to be without any content whatsoever.
Nevertheless, some of these labels remain accurate even when and where they are rejected. While Heidegger and Jaspers rejected the principle that existence precedes essence, there is no question that all three of these great existentialist thinkers were preoccupied with the problematic human condition in the modern world. Similarly, the ordinary language philosophers had their disagreements, but there were unified by a method of the analysis of ordinary language.
The school of techno-philosophy
With this caveat in mind about identifying a philosophical “school” that will almost certainly be rejected by its practitioners, I am going to identify what I will call techno-philosophy. In regard to techno-philosophy I will identify no common goals, aspirations, beliefs, principles, ideas, or ideals that belong to the practitioners of techno-philosophy, but only the common object of philosophical analysis. Techno-philosophy offers an initial exploration of novel ideas and novel facts of life in industrial society, and especially the ideas and facts of life related to technology that rapidly change within a single lifetime.
What makes the school of techno-philosophy interesting is not the special rigor or creativity of the philosophical thought in question — contemporary Anglo-American academic analytical philosophy is far more rigorous, and contemporary continental philosophy is far more imaginative — but rather the objects taken up by techno-philosophy. What are the objects of techno-philosophy? These objects are the novel productions of industrial-technological civilization, which appear and succeed each other in breathless rapidity. The fact of technological change, or even, if one would be so bold, rapid technological progress, is unprecedented. As an unprecedented aspect of life in industrial-technological civilization, rapid technological progress is an appropriate object for philosophical reflection.
The original position of technical society
The artifacts of technological progress have been produced in almost complete blindness as regard to their philosophical significance and consequences. What techno-philosophy represents is the first attempt to make philosophical sense of the artifacts of technology taken collectively, on the whole, and with an eye to their extrapolation across space and through time. In fact, the very idea of technology taken whole may be understood as a conceptual innovation of techno-philosophy, and this very idea has been called the technium by Kevin Kelly. (I wrote about the idea of the technium in Civilization and the Technium and The Genealogy of the Technium.)
Thus we can count Kevin Kelly among techno-philosophers, and even Ray Kurzweil — though Kurzweil does not seem to be interested in philosophy per se, he has pushed the limits of thinking about machine intelligence to the point that he is on the verge of philosophical questions. Thinkers in the newly emerging tradition of the technological singularity and transhumanism belong to techno-philosophy. Academic philosopher David Chalmers, known for his contributions to the philosophy of mind (and especially known for formulating the phrase “explanatory gap” to indicate the chasm between consciousness and attempted physicalistic accounts of mind) was invited to the last singularity conference and tried his hand at an essay in techno-philosophy.
Bostrom and Ćirković and techno-philosophers
The work of Nick Bostrom also represents techno-philosophy, as Professor Bostrom has engaged with a number of contemporary ideas such as superintelligence, the Fermi paradox, extraterrestrial life, transhumanism, posthumanism, the simulation hypothesis (which is a contemporary reformulation of Cartesian evil spirit), and existential risk (which is a contemporary reformulation and secularization of apocalypticism, but with a focus on mitigating apocalyptic scenarios).
Serbian astronomer and physicist Milan M. Ćirković has also dealt with many of the same questions in an admirably daring way (he has co-edited the volume Global Catastrophic Risks with Bostrom). What typifies the work of Bostrom and Ćirković — which definitely constitutes the best work in contemporary techno-philosophy — is their willingness to bring traditional philosophical sensibility to the analysis of contemporary ideas, and especially ideas enabled and facilitated by contemporary technology such as computing and space science.
The branches of industrial-technological philosophy
Industrial-technological civilization is created by practical men who eschew philosophy if they happen to be aware of it, and those with a bent for abstract or theoretical thought, and who desire a robust engagement with the world, turn to science or mathematics, where abstract and theoretical ideas can have a direct and nearly immediate impact upon the development of industrial society. Techno-philosophy picks up where these indispensable men of industrial-technological civilization leave off.
Once we understand the relationship between techno-philosophy and industrial-technological civilization (and its disruptions), and knowing the cycle of science, technology and engineering that drives such a civilization, we can posit a philosophical analysis of each stage in the escalating spiral of industrial-technological civilization, with a philosophy of the science of this civilization, a philosophy of the technology of this civilization, and a philosophy of the engineering of this civilization. Techno-philosophy, then, is the philosophy of the technology of industrial-technological civilization.
Philosophy in a time of model drift
In parallel to the emerging school of techno-philosophy, there is a quasi-philosophical field of popular expositions of science by those actively working on the frontiers of the sciences that have been most profoundly transformed by recent developments, and which are still in the process of transformation. This is the philosophy of the science of industrial-technological civilization, and it is distinct from traditional philosophy of science. The rapid developments in cosmology and physics in particular have led to model drift in these fields, and those scientists who are working on these concepts feel the need to give these abstract and theoretical conceptions a connection to ordinary human experience.
Here I have in mind the books of Brian Green, such as his exposition of string theory, The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory, as well as criticisms of string theory such as Peter Woit’s Not Even Wrong: The Failure of String Theory and the Search for Unity in Physical Law. Some of these books are more widely ranging and therefore more philosophical, such as David Deutsch’s The Fabric of Reality: The Science of Parallel Universes — and Its Implications, while some appeal to a traditional conception of “natural philosophy” as in David Grinspoon’s Lonely Planets: The Natural Philosophy of Alien Life. While these works do not constitute “techno-philosophy” as I have characterized it above, they stand in a similar relationship to the civilization the thought of which they represent.
The prospects for techno-philosophy
As techno-philosophy grows in scope, rigor, depth, and methodological sophistication, it promises to give to industrial-technological civilization something this civilization never wanted and never desired, but of which it is desperately in need: Depth. Gravitas. Intellectual seriousness. Disciplined reflection on the human condition. In a word: wisdom.
If there is anything the world needs today, it is wisdom.

What is the Church-Turing Thesis? The Church-Turing Thesis is an idea from theoretical computer science that emerged from research in the foundations of logic and mathematics, also called Church’s Thesis, Church’s Conjecture, the Church-Turing Conjecture as well as other names, that ultimately bears upon what can be computed, and thus, by extension, what a computer can do (and what a computer cannot do).
Note: For clarity’s sake, I ought to point out the Church’s Thesis and Church’s Theorem are distinct. Church’s Theorem is an established theorem of mathematical logic, proved by Alonzo Church in 1936, that there is no decision procedure for logic (i.e., there is no method for determining whether an arbitrary formula in first order logic is a theorem). But the two – Church’s theorem and Church’s thesis – are related: both follow from the exploration of the possibilities and limitations of formal systems and the attempt to define these in a rigorous way.
Even to state Church’s Thesis is controversial. There are many formulations, and many of these alternative formulations come straight from Church and Turing themselves, who framed the idea differently in different contexts. Also, when you hear computer science types discuss the Church-Turing thesis you might think that it is something like an engineering problem, but it is essentially a philosophical idea. What the Church-Turing thesis is not is as important as what it is: it is not a theorem of mathematical logic, it is not a law of nature, and it not a limit of engineering. We could say that it is a principle, because the word “principle” is ambiguous and thus covers the various formulations of the thesis.
There is an article on the Church-Turing Thesis at the Stanford Encyclopedia of Philosophy, one at Wikipedia (of course), and even a website dedicated to a critique of the Stanford article, Alan Turing in the Stanford Encyclopedia of Philosophy. All of these are valuable resources on the Church-Turing Thesis, and well worth reading to gain some orientation.
One way to formulate Church’s Thesis is that all effectively computable functions are general recursive. Both “effectively computable functions” and “general recursive” are technical terms, but there is an important different between these technical terms: “effectively computable” is an intuitive conception, whereas “general recursive” is a formal conception. Thus one way to understand Church’s Thesis is that it asserts the identity of a formal idea and an informal idea.
One of the reasons that there are many alternative formulations of the Church-Turing thesis is that there any several formally equivalent formulations of recursiveness: recursive functions, Turing computable functions, Post computable functions, representable functions, lambda-definable functions, and Markov normal algorithms among them. All of these are formal conceptions that can be rigorously defined. For the other term that constitutes the identity that is Church’s thesis, there are also several alternative formulations of effectively computable functions, and these include other intuitive notions like that of an algorithm or a procedure that can be implemented mechanically.
These may seem like recondite matters with little or no relationship to ordinary human experience, but I am surprised how often I find the same theoretical conflict played out in the most ordinary and familiar contexts. The dialectic of the formal and the informal (i.e., the intuitive) is much more central to human experience than is generally recognized. For example, the conflict between intuitively apprehended free will and apparently scientifically unimpeachable determinism is a conflict between an intuitive and a formal conception that both seem to characterize human life. Compatibilist accounts of determinism and free will may be considered the “Church’s thesis” of human action, asserting the identity of the two.
It should be understood here that when I discuss intuition in this context I am talking about the kind of mathematical intuition I discussed in Adventures in Geometrical Intuition, although the idea of mathematical intuition can be understood as perhaps the narrowest formulation of that intuition that is the polar concept standing in opposition to formalism. Kant made a useful distinction between sensory intuition and intellectual intuition that helps to clarify what is intended here, since the very idea of intuition in the Kantian sense has become lost in recent thought. Once we think of intuition as something given to us in the same way that sensory intuition is given to us, only without the mediation of the senses, we come closer to the operative idea of intuition as it is employed in mathematics.
Mathematical thought, and formal accounts of experience generally speaking, of course, seek to capture our intuitions, but this formal capture of the intuitive is itself an intuitive and essentially creative process even when it culminates in the formulation of a formal system that is essentially inaccessible to intuition (at least in parts of that formal system). What this means is that intuition can know itself, and know itself to be an intuitive grasp of some truth, but formality can only know itself as formality and cannot cross over the intuitive-formal divide in order to grasp the intuitive even when it captures intuition in an intuitively satisfying way. We cannot even understand the idea of an intuitively satisfying formalization without an intuitive grasp of all the relevant elements. As Spinoza said that the true is the criterion both of itself and of the false, we can say that the intuitive is the criterion both of itself and the formal. (And given that, today, truth is primarily understood formally, this is a significant claim to make.)
The above observation can be formulated as a general principle such that the intuitive can grasp all of the intuitive and a portion of the formal, whereas the formal can grasp only itself. I will refer to this as the principle of the asymmetry of intuition. We can see this principle operative both in the Church-Turing Thesis and in popular accounts of Gödel’s theorem. We are all familiar with popular and intuitive accounts of Gödel’s theorem (since the formal accounts are so difficult), and it is not usual to make claims for the limitative theorems that go far beyond what they formally demonstrate.
All of this holds also for the attempt to translate traditional philosophical concepts into scientific terms — the most obvious example being free will, supposedly accounted for by physics, biochemistry, and neurobiology. But if one makes the claim that consciousness is nothing but such-and-such physical phenomenon, it is impossible to cash out this claim in any robust way. The science is quantifiable and formalizable, but our concepts of mind, consciousness, and free will remain stubbornly intuitive and have not been satisfyingly captured in any formalism — the determination of any such satisfying formalization could only be determined by intuition and therefore eludes any formal capture. To “prove” determinism, then, would be as incoherent as “proving” Church’s Thesis in any robust sense.
There certainly are interesting philosophical arguments on both sides of Church’s Thesis — that is to say, both its denial and its affirmation — but these are arguments that appeal to our intuitions and, most crucially, our idea of ourselves is intuitive and informal. I should like to go further and to assert that the idea of the self must be intuitive and cannot be otherwise, but I am not fully confident that this is the case. Human nature can change, albeit slowly, along with the human condition, and we could, over time — and especially under the selective pressures of industrial-technological civilization — shape ourselves after the model of a formal conception of the self. (In fact, I think it very likely that this is happening.)
I cannot even say — I would not know where to begin — what would constitute a formal self-understanding of the self, much less any kind of understanding of a formal self. Well, maybe not. I have written elsewhere that the doctrine of the punctiform present (not very popular among philosophers these days, I might add) is a formal doctrine of time, and in so far as we identify internal time consciousness with the punctiform present we have a formal doctrine of the self.
While the above account is one to which I am sympathetic, this kind of formal concept — I mean the punctiform present as a formal conception of time — is very different from the kind of formality we find in physics, biochemistry, and neuroscience. We might assimilate it to some mathematical formalism, but this is an abstraction made concrete in subjective human experience, not in physical science. Perhaps this partly explains the fashionable anti-philosophy that I have written about.
