In my last post, The Retrodiction Wall, I introduced several ideas that I think were novel, among them:
● A retrodiction wall, complementary to the prediction wall, but in the past rather than the present
● A period of effective history lying between the retrodiction wall in the past and the prediction wall in the future; beyond the retrodiction and prediction walls lies inaccessible history that is not a part of effective history
● A distinction between diachronic and synchronic prediction walls, that is to say, a distinction between the prediction of succession and the prediction of interaction
● A distinction between diachronic and synchronic retrodiction walls, that is to say, a distinction between the retrodiction of succession and the retrodiction of interaction
I also implicitly formulated a principle, though I didn’t give it any name, parallel to Einstein’s principle (also without a name) that mathematical certainty and applicability stand in inverse proportion to each other: historical predictability and historical relevance stand in inverse proportion to each other. When I can think of a good name for this I’ll return to this idea. For the moment, I want to focus on the prediction wall and the retrodiction wall as the boundaries of effective history.
In The Retrodiction Wall I made the assertion that, “Effective history is not fixed for all time, but expands and contracts as a function of our knowledge.” An increase in knowledge allows us to push the boundaries the prediction and retrodiction walls outward, as a diminution of knowledge means the contraction of prediction and retrodiction boundaries of effective history.
We can go farther than this is we interpolate a more subtle and sophisticated conception of knowledge and prediction, and we can find this more subtle and sophisticated understand in the work of Frank Knight, which I previously cited in Existential Risk and Existential Uncertainty. Knight made a tripartite distinction between prediction (or certainty), risk, and uncertainty. Here is the passage from Knight that I quoted in Addendum on Existential Risk and Existential Uncertainty:
1. A priori probability. Absolutely homogeneous classification of instances completely identical except for really indeterminate factors. This judgment of probability is on the same logical plane as the propositions of mathematics (which also may be viewed, and are viewed by the writer, as “ultimately” inductions from experience).
2. Statistical probability. Empirical evaluation of the frequency of association between predicates, not analyzable into varying combinations of equally probable alternatives. It must be emphasized that any high degree of confidence that the proportions found in the past will hold in the future is still based on an a priori judgment of indeterminateness. Two complications are to be kept separate: first, the impossibility of eliminating all factors not really indeterminate; and, second, the impossibility of enumerating the equally probable alternatives involved and determining their mode of combination so as to evaluate the probability by a priori calculation. The main distinguishing characteristic of this type is that it rests on an empirical classification of instances.
3. Estimates. The distinction here is that there is no valid basis of any kind for classifying instances. This form of probability is involved in the greatest logical difficulties of all, and no very satisfactory discussion of it can be given, but its distinction from the other types must be emphasized and some of its complicated relations indicated.
Frank Knight, Risk, Uncertainty, and Profit, Chap. VII
This passage from Knight’s book (as the entire book) is concerned with applications to economics, but the kernel of Knight’s idea can be generalized beyond economics to generally represent different stages in the acquisition of knowledge: Knight’s a priori probability corresponds to certainty, or that which is so exhaustively known that it can be predicted with precision; Knight’s statistical probably corresponds with risk, or partial and incomplete knowledge, or that region of human knowledge where the known and unknown overlap; Knight’s estimates correspond to unknowns or uncertainty.
Knight formulates his tripartite distinction between certainty, risk, and uncertainty exclusively in the context of prediction, and just as Knight’s results can be generalized beyond economics, so too Knight’s distinction can be generalized beyond prediction to also embrace retrodiction. In The Retrodiction Wall I generalized John Smart‘s exposition of a prediction wall in the future to include a retrodiction wall in the past, both of which together define the boundaries of effective history. These two generalizations can be brought together.
A prediction wall in the future or a retrodiction wall in the past are, as I noted, functions of knowledge. That means we can understand this “boundary” not merely as a threshold that is crossed, but also as an epistemic continuum that stretches from the completely unknown (the inaccessible past or future that lies utterly beyond the retrodiction or prediction wall) through an epistemic region of prediction risk or retrodiction risk (where predictions or retrodictions can be made, but are subject to at least as many uncertainties as certainties), to the completely known, in so far as anything can be completely known to human beings, and therefore well understood by us and readily predictable.
Introducing and integrating distinctions between prediction and retrodiction walls, and among prediction, risk and uncertainty gives a much more sophisticated and therefore epistemically satisfying structure to our knowledge and how it is contextualized in the human condition. The fact that we find ourselves, in medias res, living in a world that we must struggle to understand, and that this understanding is an acquisition of knowledge that takes place in time, which is asymmetrical as regards the past and future, are important features of how we engage with the world.
This process of making our model of knowledge more realistic by incorporating distinctions and refinements is not yet finished (nor is it ever likely to be). For example, the unnamed principle alluded to above — that of the inverse relation between historical predictability and relevance, suggests that the prediction and retrodiction walls can be penetrated unevenly, and that our knowledge of the past and future is not consistent across space and time, but varies considerably. An inquiry that could demonstrate this in any systematic and schematic way would be more complicated than the above, so I will leave this for another day.

Prediction in Science
One of the distinguishing features of science as a system of thought is that it makes testable predictions. The fact that scientific predictions are testable suggests a methodology of testing, and we call the scientific methodology of testing experiment. Hypothesis formation, prediction, experimentation, and resultant modification of the hypothesis (confirmation, disconfirmation, or revision) are all essential elements of the scientific method, which constitutes an escalating spiral of knowledge as the scientific method systematically exposes predictions to experiment and modifies its hypotheses in the light of experimental results, which leads in turn to new predictions.
The escalating spiral of knowledge that science cultivates naturally pushes that knowledge into the future. Sometimes scientific prediction is even formulated in reference to “new facts” or “temporal asymmetries” in order to emphasize that predictions refer to future events that have not yet occurred. In constructing an experiment, we create a few set of facts in the world, and then interpret these facts in the light of our hypothesis. It is this testing of hypotheses by experiment that establishes the concrete relationship of science to the world, and this is also a source of limitation, for experiments are typically designed in order to focus on a single variable and to that end an attempt is made to control for the other variables. (A system of thought that is not limited by the world is not science.)
Alfred North Whitehead captured this artificial feature of scientific experimentation in a clever line that points to the difference between scientific predictions and predictions of a more general character:
“…experiment is nothing else than a mode of cooking the facts for the sake of exemplifying the law. Unfortunately the facts of history, even those of private individual history, are on too large a scale. They surge forward beyond control.”
Alfred North Whitehead, Adventures of Ideas, New York: The Free Press, 1967, Chapter VI, “Foresight,” p. 88
There are limits to prediction, and not only those pointed out by Whitehead. The limits to prediction have been called the prediction wall. Beyond the prediction wall we cannot penetrate.
The Prediction Wall
John Smart has formulated the idea of a prediction wall in his essay, “Considering the Singularity,” as follows:
With increasing anxiety, many of our best thinkers have seen a looming “Prediction Wall” emerge in recent decades. There is a growing inability of human minds to credibly imagine our onrushing future, a future that must apparently include greater-than-human technological sophistication and intelligence. At the same time, we now admit to living in a present populated by growing numbers of interconnected technological systems that no one human being understands. We have awakened to find ourselves in a world of complex and yet amazingly stable technological systems, erected like vast beehives, systems tended to by large swarms of only partially aware human beings, each of which has only a very limited conceptualization of the new technological environment that we have constructed.
Business leaders face the prediction wall acutely in technologically dependent fields (and what enterprise isn’t technologically dependent these days?), where the ten-year business plans of the 1950’s have been replaced with ten-week (quarterly) plans of the 2000’s, and where planning beyond two years in some fields may often be unwise speculation. But perhaps most astonishingly, we are coming to realize that even our traditional seers, the authors of speculative fiction, have failed us in recent decades. In “Science Fiction Without the Future,” 2001, Judith Berman notes that the vast majority of current efforts in this genre have abandoned both foresighted technological critique and any realistic attempt to portray the hyper-accelerated technological world of fifty years hence. It’s as if many of our best minds are giving up and turning to nostalgia as they see the wall of their own conceptualizing limitations rising before them.

I would to suggest that there are at least two prediction walls: synchronic and diachronic. The prediction wall formulated above by John Smart is a diachronic prediction wall: it is the onward-rushing pace of events, one following the other, that eventually defeats our ability to see any recognizable order or structure of the future. The kind of prediction wall to which Whitehead alludes is a synchronic prediction wall, in which it is the outward eddies of events in the complexity of the world’s interactions that make it impossible for us to give a complete account of the consequences of any one action. (Cf. Axes of Historiography)
Retrodiction and the Historical Sciences
Science does not live by prediction alone. While some philosophers of science have questioned the scientificity of the historical sciences because they could not make testable (and therefore falsifiable) predictions about the future, it is now widely recognized that the historical sciences don’t make predictions, but they do make retrodictions. A retrodiction is a prediction about the past.
The Oxford Dictionary of Philosophy by Simon Blackburn (p. 330) defines retrodiction thusly:
retrodiction The hypothesis that some event happened in the past, as opposed to the prediction that an event will happen in the future. A successful retrodiction could confirm a theory as much as a successful prediction.
As with predictions, there is also a limit to retrodiction, and this is the retrodiction wall. Beyond the retrodiction wall we cannot penetrate.
I haven’t been thinking about this idea for long enough to fully understand the ramifications of a retrodiction wall, so I’m not yet clear about whether we can distinction diachronic retrodiction and synchronic retrodiction. Or, rather, it would be better to say that the distinction can certainly be made, but that I cannot think of good contrasting examples of the two at the present time.
We can define a span of accessible history that extends from the retrodiction wall in the past to the prediction wall in the future as what I will call effective history (by analogy with effective computability). Effective history can be defined in a way that is closely parallel to effectively computable functions, because all of effective history can be “reached” from the present by means of finite, recursive historical methods of inquiry.
Effective history is not fixed for all time, but expands and contracts as a function of our knowledge. At present, the retrodiction wall is the Big Bang singularity. If anything preceded the Big Bang singularity we are unable to observe it, because the Big Bang itself effectively obliterates any observable signs of any events prior to itself. (Testable theories have been proposed that suggest the possibility of some observable remnant of events prior to the Big Bang, as in conformal cyclic cosmology, but this must at present be regarded as only an early attempt at such a theory.)
Prior to the advent of scientific historiography as we know it today, the retrodiction wall was fixed at the beginning of the historical period narrowly construed as written history, and at times the retrodiction wall has been quite close to the present. When history experiences one of its periodic dark ages that cuts it off from his historical past, little or nothing may be known of a past that once familiar to everyone in a given society.
The emergence of agrarian-ecclesiastical civilization effectively obliterated human history before itself, in a manner parallel to the Big Bang. We know that there were caves that prehistorical peoples visited generation after generation for time out of mind, over tens of thousands of years — much longer than the entire history of agrarian-ecclesiastical civilization, and yet all of this was forgotten as though it had never happened. This long period of prehistory was entirely lost to human memory, and was not recovered again until scientific historiography discovered it through scientific method and empirical evidence, and not through the preservation of human memory, from which prehistory had been eradicated. And this did not occur until after agrarian-ecclesiastical civilization had lapsed and entirely given way to industrial-technological civilization.
We cannot define the limits of the prediction wall as readily as we can define the limits of the retrodiction wall. Predicting the future in terms of overall history has been more problematic than retrodicting the past, and equally subject to ideological and eschatological distortion. The advent of modern science compartmentalized scientific predictions and made them accurate and dependable — but at the cost of largely severing them from overall history, i.e., human history and the events that shape our lives in meaningful ways. We can make predictions about the carbon cycle and plate tectonics, and we are working hard to be able to make accurate predictions about weather and climate, but, for the most part, our accurate predictions about the future dispositions of the continents do not shape our lives in the near- to mid-term future.
I have previously quoted a famous line from Einstein: “As far as the laws of mathematics refer to reality, they are not certain; and as far as they are certain, they do not refer to reality.” We might paraphrase this Einstein line in regard to the relation of mathematics to the world, and say that as far as scientific laws of nature predict events, these events are irrelevant to human history, and in so far as predicted events are relevant to human beings, scientific laws of nature cannot predict them.
Singularities Past and Future
As the term “singularity” is presently employed — as in the technological singularity — the recognition of a retrodiction wall in the past complementary to the prediction wall in the future provides a literal connection between the historiographical use of “singularity” and the use of the term “singularity” in cosmology and astrophysics.
Theorists of the singularity hypothesis place a “singularity” in the future which constitutes an absolute prediction wall beyond which history is so transformed that nothing beyond it is recognizable to us. This future singularity is not the singularity of astrophysics.
If we recognize the actual Big Bang singularity in the past as the retrodiction wall for cosmology — and hence, by extension, for Big History — then an actual singularity of astrophysics is also at the same time an historical singularity.

In my last post, The Science of Time, I discussed the possibility of taking an absolutely general perspective on time and how this can be done in a way that denies time or in a way that affirms time, after the manner of big history.
David Christian, whose books on big history and his Teaching Company lectures on Big History have been seminal in the field, in the way of introduction to his final lectures, in which he switches from history to speculation on the future, relates that in his early big history courses his students felt as though they were cut off rather abruptly when he had brought them through 13.7 billion years of cosmic history only to drop them unceremoniously in the present without making any effort to discuss the future. It was this reaction that prompted him to continue beyond the present and to try to say something about what comes next.
Another way to understand this reaction of Christian’s students is that they wanted to see the whole of the history they have just been through placed in an even larger, more comprehensive context, and to do this requires going beyond history in the sense of an account of the past. To put the whole of history into a larger context means placing it within a cosmology that extends beyond our strict scientific knowledge of past and future — that which can be observed and demonstrated — and comprises a framework in the same scientific spirit but which looks beyond the immediate barriers to observation and demonstration.
Elsewhere in David Christian’s lectures (if my memory serves) he mentioned how some traditionalist historians, when they encounter the idea of big history, reject the very idea because history has always been about documents and eponymously confined to to the historical period when documents were kept after the advent of literacy. According to this reasoning, anything that happened prior to the invention of written language is, by definition, not history. I have myself encountered similar reasoning as, for example, when it is claimed that prehistory is not history at all because it happened prior to the existence of written records, which latter define history.
This a sadly limited view of history, but apparently it is a view with some currency because I have encountered it in many forms and in different contexts. One way to discredit any intellectual exercise is to define it so narrowly that it cannot benefit from the most recent scientific knowledge, and then to impugn it precisely for its narrowness while not allowing it to change and expand as human knowledge expands. The explosion in scientific knowledge in the last century has made possible a scientific historiography that simply did not exist previously; to deny that this is history on the basis of traditional humanistic history being based on written records means that we must then define some new discipline, with all the characteristics of traditional history, but expanded to include our new knowledge. This seems like a perverse attitude to me, but for some people the label of their discipline is important.
Call it what you will then — call it big history, or scientific historiography, or the study of human origins, or deny that it is history altogether, but don’t try to deny that our knowledge of the past has expanded exponentially since the scientific method has been applied to the past.
In this same spirit, we need to recognize that a greatly expanded conception of history needs to reach into the future, that a scientific futurism needs to be part of our expanded conception of the totality of time and history — or whatever it is that results when we apply Russell’s generalization imperative to time. Once again, it would be unwise to be overly concerned with what we call his emerging discipline, whether it be the totality of time or the whole of time or temporal infinitude or ecological temporality or what Husserl called omnitemporality or even absolute time.
Part of this grand (historical) effort will be a future science of civilizations, as the long term and big picture conception of civilization is of central human interest in this big picture of time and history. We not only want to know the naturalistic answers to traditional eschatological questions — Where did we come from? Where are we going? — but we also want to know the origins and destiny of what we have ourselves contributed to the universe — our institutions, our ideas, civilization, the technium, and all the artifacts of human endeavor.

19 February 2012
Recently (in Don’t Cry for the Papers) I wrote that, “Books will be a part of human life as long as there are human beings (or some successor species engaged in civilizational activity, or whatever cultural institution is the successor to civilization).” While this was only a single line thrown out as an aside in a discussion of newspapers and magazines, I had to pause over this to think about it and make sure that I would get my phrasing right, and in doing so I realized that there are several ideas implicit in this formulation.
Since I make an effort to always think in terms of la longue durée, I have conditioned myself to note that current forms (of civilization, or whatever else is being considered) are always likely to be supplanted by changed forms in the future, so when I said that books, like the poor, will always be with us, for the sake of completeness I had to note that human forms may be supplanted by a successor species and that civilization may be supplanted by a a successor institution. Both the idea of the post-human and the post-civilizational are interesting in their own right. I have briefly considered posthumanity and human speciation in Against Natural History, Right and Left (as well as other posts such as Addendum on the Avoidance of Moral Horror), but the idea of a successor to civilization is something that begs further consideration.
Now, in the sense, everything that I have written about futurist scenarios for the successor to contemporary industrial-technological civilization (which I have described in Three Futures, Another Future: The New Agriculturalism, and other posts) can be taken as attempts to outline what comes after civilization in so far as we understand civilization as contemporary industrial-technological civilization. This investigation of post-industrial civilization is an important aspect of an analytic and theoretical futurism, but we must go further in order to gain a yet more comprehensive perspective that places civilization within the longest possible historical context.
I have adopted the convention of speaking of “civilization” as comprising all settled, urbanized cultures that have emerged since the Neolithic Agricultural Revolution. This is not the use that “civilization” has in classic humanistic historiography, but I have discussed this elsewhere; for example, in Jacob Bronowski and Radical Reflection I wrote:
…Bronowski refers to “civilization as we know it” as being 12,000 years old, which means that he is identifying civilization with the Neolithic Agricultural Revolution and the emergence of settled life in villages and eventually cities.
Taking this long and comprehensive view of civilization, we still must contrast civilization with its prehistoric antecedents. When one realizes that the natural sciences have been writing the history of prehistory since the methods, the technologies, and the conceptual infrastructure for this have been developed since the late nineteenth century, and that paleolithic history itself admits of cultures (the Micoquien, the Mousterian, the Châtelperronian, the Aurignacian, and the Gravettian, for example), it becomes clear that “culture” is a more comprehensive category than “civilization,” and that culture is the older category. The cultures of prehistory are the antecedent institutions to the institution of civilization. This immediately suggests, in the context of futurism, that there could be a successor institution to civilization that no longer could be strictly called “civilization” but which still constituted a human culture.
Thus the question, “What comes after civilization?” when understood in an appropriately radical philosophical sense, invites us to consider post-civilizational human cultures that will not only differ profoundly from contemporary industrial-technological civilization, but which will differ profoundly from all human civilization from the Neolithic Agricultural Revolution to the present day.
Human speciation, if it occurs, will profoundly affect the development of post-human, post-civilizational cultural institutions. I have mentioned in several posts (e.g., Gödel’s Lesson for Geopolitics) that Francis Fukuyama felt obligated to add the qualification to this “end of history” thesis that if biotechnology made fundamental changes to human beings, this could result in a change to human nature, and then all bets are off for the future: in this eventuality, history will not end. Changed human beings, possibly no longer human sensu stricto, may have novel conceptions of social organization and therefore also novel conceptions of social and economic justice. From these novel conceptions may arise cultural institutions that are no longer “civilization” as we here understand civilization.
Above I wrote, “human speciation, if it occurs,” and I should mention that my only hesitation here is that social or technological means may be employed in the attempt to arrest human evolution at more-or-less its present stage of development, thus forestalling human speciation. Thus my qualification on human speciation in no way arises from a hesitation to acknowledge the possibility. As far as I am concerned, human being is first and foremost biological being, and biological being is always subject to natural selection. However, technological intervention might possibly overtake natural selection, in which case we will continue to experience selection as a species, but it will be social selection and technological selection rather than natural selection.
In terms of radical scenarios for the near- and middle-term future, the most familiar on offer at present (at least, the most familiar that has some traction in the public mind) is that of the technological singularity. I have recounted in several posts the detailed predictions that have been made, including several writers and futurists who have placed definite dates on the event. For example, Vernor Vinge, who proposed the idea of the technological singularity, wrote that, “Within thirty years, we will have the technological means to create superhuman intelligence. Shortly after, the human era will be ended.” (This is from his original essay on the technological singularity published in 1993, which places the date of the advent of the technological singularity at 2023 or sooner; I understand that Mr. Vinge has since revised his forecast.)
To say that “the human era will be ended,” is certainly to predict a radical development, since it postulates a post-human future within the life time of many now living today (much like the claim that, “Verily I say unto you, That there be some of them that stand here, which shall not taste of death, till they have seen the kingdom of God come with power.”). If I had to predict a radical post-human future in the near- to middle-term future I would opt not for post-human machine intelligence but for human speciation facilitated by biotechnology. This latter scenario seems to me far more likely and far more plausible than the technological singularity, since we already have the technology in its essentials; it is only a matter of refining and applying existing biotechnology.
I make no predictions and set no dates because the crowding of seven billion (and counting) human beings on a single planet militates against radical changes to our species. Social pressures to avoid speciation would make such a scenario unlikely in the near- to middle-term future. If we couple human speciation with the scenario of extraterrestrialization, however, everything changes, but this pushes the scenario further into the future because we do not yet possess the infrastructure necessary to extraterrestrialization. Again, however, as with human speciation through biotechnology, we have all the technology necessary to extraterrestrialization, and it is only a matter of refining and applying existing technologies.
From this scenario of human speciation coupled with extraterrestrialization there would unquestionably emerge post-human, post-civilizational cultural institutions that would be propagated into the distant future, possibly marginalizing, and possibly entirely supplanting, human beings and human civilization as we know it today. It is to be expected that these institutions will be directly related to the way of life adopted in view of such a scenario, and this way of life will be sufficiently different from our own that its institutions and its values and its norms would be unprecedented from our perspective.

A revaluation of agricultural civilization
In several posts I have made a tripartite distinction in human history between hunter-gatherer nomadism, agriculturalism, and industrialism. There is a sense, then, from the perspective of la longue duree, that the macro-historical division of agriculturalism constitutes the “middle ages” of human social development. Prior to agriculturalism, nothing like this settled way of life even existed; now, later, from the perspective of industrialized civilization, agriculture is an enormous industry that can feed seven billion people, but it is a demographically marginal activity that occupies only a small fragment of our species. During those “middle ages” of agriculturalism (comprising maybe fifteen thousand years of human society) the vast bulk of our species was engaged in agricultural production. The very small class of elites oversaw agricultural production and its distribution, and the small class of the career military class or the career priestly class facilitated the work of elites in overseeing agricultural production. This civilizational focus is perhaps unparalleled by any other macro-historical epoch of human social development (and I have elsewhere implicitly referred to this focus in Pure Agriculturalism).
The advent of agricultural civilization was simultaneously the advent of settled civilization, and the transition from agriculturalism to industrialism left the institution of settled civilization in place. Other continuities are also still in place, and many of these continuities from agriculturalism to industrialism are simply the result of the youth of industrial civilization. When industrial civilization is ten thousand years old — should it survive so long, which is not at all certain — I suspect that it will preserve far fewer traces of its agricultural past. For the present, however, we live in a milieu of agricultural institutions held over from the long macro-historical division of agriculturalism and emergent institutions of a still-inchoate industrialism.
The institutions of agricultural civilization are uniquely macabre, and it is worthwhile to inquiry as to how an entire class of civilizations (all the civilizations that belong within the macro-historical division of settled agriculturalism) could come to embody a particular (and, indeed, a peculiar) moral-aesthetic tenor. What do I mean by “macabre”? The online Merriam-Webster dictionary defines “macabre” as follows:
1: having death as a subject: comprising or including a personalized representation of death
2: dwelling on the gruesome
3: tending to produce horror in a beholder
All of the above characterize settled agricultural civilization, which has death as its subject, dwells upon the gruesome, and as a consequence tends to produce horror in the beholder.
The thousand years of medieval European society, which approximated pure agriculturalism perhaps more closely than many other agricultural civilizations (and which we might call a little bit of civilization in its pure form), stands as a monument to the macabre, especially after the experience of the Black Death (bubonic plague), which gave the culture of Europe a decidedly death-obsessed aspect still to be seen in graphically explicit painting and sculpture. But medieval Europe is not unique in this respect; all settled agricultural civilization, to a greater or a lesser extent, has a macabre element at its core. The Agricultural Apocalypse that I wrote about in my previous post constitutes a concrete expression of the horrors that agricultural civilization has inflicted upon itself. What makes agricultural civilization so horrific? What is the source of the macabre Weltanschauung of agriculturalism?
Both the lives of nomadic hunter-gatherers and the lives of settled agriculturalists are bound up with a daily experience of death: human beings must kill in order to live, and other living beings must die so that human beings can live. Occasionally a human being dies so that another species may live, and while this still happens in our own time when someone is eaten by a bear or a mountain lion, it happens much less often that the alternative, which explains why there are seven billion human beings on the planet while no other vertebrate predator comes close to these numbers. The only vertebrate species that flourish are those that we allow to flourish (there are, for example, about sixteen billion chickens in the world), with the exception of a few successful parasitic species such as rats and seagulls. (Even then, there are about five billion rats on the planet, and each rat weighs only a faction of the mass of a human being, so that total human biomass is disproportionately great.)
Although nomadic hunter-gatherers and settled agriculturalists both confront pervasive experiences of death, the experience of death is different in each case, and this difference in the experience and indeed in the practice of death informs everything about human life that is bound up in this relationship to death. John Stuart Mill wrote in his The Utility of Religion:
“Human existence is girt round with mystery: the narrow region of our experience is a small island in the midst of a boundless sea, which at once awes our feelings and stimulates our imagination by its vastness and its obscurity. To add to the mystery, the domain of our earthly existence is not only an island in infinite space, but also in infinite time. The past and the future are alike shrouded from us: we neither know the origin of anything which is, nor, its final destination. If we feel deeply interested in knowing that there are myriads of worlds at an immeasurable, and to our faculties inconceivable, distance from us in space; if we are eager to discover what little we can about these worlds, and when we cannot know what they are, can never satiate ourselves with speculating on what they may be; is it not a matter of far deeper interest to us to learn, or even to conjecture, from whence came this nearer world which we inhabit; what cause or agency made it what it is, and on what powers depend its future fate?”
While Mill wrote that human existence is girt round with mystery, he might well have said that human existence is girt round with death, and in many religious traditions death and mystery or synonymous. The response to the death that surrounds human existence, and the kind of death that surrounds human existence, shapes the mythological traditions of the people so girt round.
Joseph Campbell explicitly recognized the striking difference in mythologies between nomadic hunter-gatherers and settled agricultural peoples. This is a theme to which Campbell returns time and again in his books and lectures. The mythologies of hunting peoples, Campbell maintained, revolved around placating the spirits of killed prey, while the mythologies of agricultural peoples resolved around sacrifice, according to the formula that, since life grows out of death, in order to create more life, one must create more death. Hence sacrifice. Campbell clearly explains a link between the mythologies peculiar to macro-historically distinct peoples, but why should peoples respond so strongly (and so differently) to distinct experiences of death? And, perhaps as importantly, why should peoples respond mythologically to death? To answer this question demands a more fundamental perspective upon human life in its embeddedness in socio-cultural milieux, and we can find such a perspective in a psychoanalytic interpretation of history derived from Freud.
It is abundantly obvious, in observing the struggle for life, that organisms are possessed of a powerful instinct to preserve the life of the individual at all costs and to reproduce that life (sometimes called eros or libido), but Freud theorized that, in addition to the survival instinct that there is also a “death drive” (sometimes called thanatos). Here is Freud’s account of the death drive:
“At one time or another, by some operation of force which still completely baffles conjecture, the properties of life were awakened in lifeless matter. Perhaps the process was a prototype resembling that other one which later in a certain stratum of living matter gave rise to consciousness. The tension then aroused in the previously inanimate matter strove to attain an equilibrium; the first instinct was present, that to return to lifelessness. The living substance at that time had death within easy reach; there was probably only a short course of life to run, the direction of which was determined by the chemical structure of the young organism. So through a long period of time the living substance may have been constantly created anew, and easily extinguished, until decisive external influences altered in such a way as to compel the still surviving substance to ever greater deviations from the original path of life, and to ever more complicated and circuitous routes to the attainment of the goal of death. These circuitous ways to death, faithfully retained by the conservative instincts, would be neither more nor less than the phenomena of life as we now know it. If the exclusively conservative nature of the instincts is accepted as true, it is impossible to arrive at any other suppositions with regard to the origin and goal of life.”
Sigmund Freud, Beyond the Pleasure Principle, authorized translation from the second German edition by C. J. M. Hubback, London and Vienna: The International Psycho-Analytical Press, 1922, pp. 47-48
The death drive, or thanatos, does not appear to be as urgent as the drive to live and to reproduce, but according to Freud it is equally implicated in society and culture. Moreover, given the emergence of war from the same settled agricultural societies that practiced a mythology of sacrifice (according to Campbell), there has been a further “production” of death by the social organization made possible by settled societies. It is to be expected that the production of death by sacrifice in order to ensure a good harvest would become entangled with the production of death in order to ensure the continuity of the community, and indeed in societies in which war became highly ritualized (e.g., Aztec civilization and Japanese civilization) there is a strong element of sacrifice in combat.
Freud’s explanation of the death drive may strike the reader as a bit odd and perhaps unlikely, but the mechanism that Freud is proposing is not all that different from Sartre’s contention that being-for-itself seeks to become being-in-itself (to put it simply, everyone wants to be God): life — finite life, human life — is problematic, unstable, uncertain, subject to calamity, and pregnant with every kind of danger. Why would such a contingent, finite being not desire to possess the quiescence and security of being-in-itself, to be free of all contingencies, which Shakespeare called all the ills that flesh is heir to? The mythologies that Campbell describes as being intrinsic to nomadic and settled peoples are mechanisms that attempt to restore the equilibrium to the world that has been disturbed by human activity.
Agricultural civilization is the institutionalization of the death drive. The mythology of sacrifice institutionalizes death as the norm and even the ideal of agricultural civilizations. As such, settled agricultural civilization is (has been) a pathological permutation of human society that has resulted in the social equivalent of neurotic misery. That is to say, agricultural civilization is a civilization of neurotic misery, but all civilization need not be neurotically miserable. The Industrial Revolution has accomplished part of the world of overcoming the institutions of settled agriculturalism, but we still retain much of its legacy. To make the complete transition from the neurotic misery of settled agricultural civilization to ordinary civilizational unhappiness will require an additional effort above and beyond industrialization.
Despite the explicit recognition of a Paleolithic Golden Age prior to settled agriculturalism, there is a strong bias in contemporary civilization against nomadism and in favor of settled civilization. Both Kenneth Clark’s Civilisation: A Personal View and Jacob Bronowski’s The Ascent of Man (both of which I have cited with approval in many posts) make broad evaluative judgments to the detriment of nomadic societies — an entirely superfluous judgment, as though the representatives of settled civilization felt that they needed to defend an existential orientation of their civilization by condemning the way of life of uncivilized peoples, who are called savages and barbarians. The contempt that has been shown for the world’s surviving nomadic peoples — the Sami, the Gypsies, and others — as well as programs of forced sedentarization — e.g., among the Kyrgyz — show the high level of emotional feeling that still attaches to the difference between fundamentally distinct forms of life, even when one pattern of life has become disproporationately successful and no longer needs to defend itself against the depredations of the other.
Given this low esteem in which existential alternatives are held, it is important to see settled agricultural civilization, as well as its direct descendent, settled industrial civilization, in their true colors and true dimensions, and to explicitly recognize the pathological and explicitly macabre elements of the civilization that we have called our own in order to see it for what it is and therefore to see its overcoming as an historical achievement for the good the species.
We are not yet free of the institutions of settled agricultural civilization, which means that we are not yet free of a Weltanschauung constructed around macabre rituals focused on death. And despite the far-reaching changes to life that have come with the Industrial Revolution, there is no certainly that the developments that separate us from the settled agricultural macabre will continue. I wrote above that, given the consolidation of industrial civilization, we will probably have institutions far less agricultural in character, but it remains possible that the industrialism may falter, may collapse, or may even, after consolidating itself as a macro-historical division, give way to a future macro-historical division in which the old ways of agriculturalism will be reasserted.
I count among the alternatives of future macro-historical developments the possibility of pastoralization and neo-agriculturalism. In any civilization largely constituted by either the historical processes of pastoralization of neo-agriculturalism, agriculture would once again play a central and perhaps a dominant role in the life of the people. In a future macro-historical division in which agriculture was once again the dominant feature of human experience, I would expect that the macabre character of agricultural civilization would once against reassert itself in a new mythology eventually consolidated in the axialization of a future historical paradigm centered on agriculture.

I have been listening to Cro-Magnon: How the Ice Age Gave Birth to the First Modern Humans by Brian Fagan and am thoroughly enjoying the book. Professor Fagan has written a great many books about prehistory and climatology, and I have previously recommended his lectures for The Teaching Company, Human Prehistory and the First Civilizations. In fact, I was so enthusiastic about this set of lectures that I urged by mother to listen to them also, since she shares my interest in prehistory and anthropology. This led to an interesting coincidence. My mother was listening to these lectures before she took a cruise to Alaska with one of my sisters. A day later when she got on the cruise ship she heard the distinctive voice of the on-board naturalist for this cruise, and asked him, “Are you Brian Fagan?” And indeed it was Brian Fagan.
In any case, I have derived a lot of value (and a lot of enjoyment) from the works of Professor Fagan, and I heartily recommend them. In this recent (2011) book on Cro-Magnons, Fagan is in fine form, delivering both anecdote and research results that enliven the human condition in its earliest iteration. Fagan places particular emphasis on two events, although I hesitate to call them “events” since they have more to do with the longue durée than with any ephemeral or momentary event.
He references the Mount Toba eruption, thought to have happened between 69,000 and 77,000 years ago, and which may have had a major impact upon our early ancestors. Although Fagan emphasizes (as do most anthropologists) that human beings were anatomically modern from the emergence of Homo sapiens (between 200,000 and 120,000 years ago), he implies without explicitly stating that a kind of cognitive modernity emerged during the period of privation following the Mount Toba eruption. I would suggest that the climatological winter following the eruption may have provided an opportunity for cognitive competition, and therefore triggered the emergence of cognitive modernity through evolutionary escalation. In short, only the cleverest of the at-that-time very small population of Homo sapiens in Africa would have survived.
Professor Fagan also places great emphasis upon the last glacial maximum (between 26,500 and 19,000–20,000 years ago) of the last ice age, when the human population, by that time having passed into Europe and Asia, was again under great climatological pressure, and came through a very difficult time. Most human beings alive today would possess neither the skills nor the knowledge to survive during the last glacial maximum, were they set down in Europe or Asia 25,000 years ago. And it is important to emphasize that it is skills and knowledge that make the difference: we are not talking about hulking, cold-weather-adapted Neanderthals, we are talking about fully anatomically modern human beings, indistinguishable from ourselves.
Both of these events — the Mount Toba eruption and the last glacial maximum — were cold weather events. Our ancestors survived and even thrived because of the skills that they developed to carry them through extreme cold weather conditions. Professor Fagan mentions winters lasting nine months of the year, and temperatures routinely colder that our relatively balmy inter-glacial temperatures. And they mastered these skills without the sort of high technology that we would imagine would be necessary to survive such conditions.
Professor Fagan emphasizes the importance of the eyed needle, which he compares to the domestication of fire as an event of the first importance in the history of human technology. It was the eyed needle, cut from bone or antler with a very fine flint blade, that made possible the sewing of close-fitting clothes, and it was close fitting clothes mostly made of reindeer hides that made survival through the past glacial maximum possible.
We are all the descendents of these hearty ancestors who found ingenious ways to live in a hostile climate — and not only a hostile climate, but a climate that changed dramatically in the course of a lifetime, and even more dramatically over a few generations. And while these ice age ancestors were not Eskimos sensu stricto, the closest thing to their lives is preserved by the remnants of the peoples of the far northern polar regions who still survive in extreme cold, who still wear the skins of the animals they eat, and who still cling to the nomadic hunter-gatherer way of life, and who still have the migration of the reindeer at the center of their lives and their culture. The reindeer is perhaps the central animal in human experience taken over the longue durée.
It is interesting to note in this connection that Toynbee, in his attempt at a systematic survey of civilizations, did identify an “Eskimo civilization,” but he identified it as an “arrested civilization” and in this capacity classed it with Polynesian civilization and with nomads generally speaking. These “arrested” civilizations are not to be confused with the “abortive” civilizations of Viking Scandinavia and Far Western Christendom (the “Celtic Fringe”).
The “arrested” civilizations actually play a central role in Toynbee’s “challenge and response” argument for the vitality of civilizations. Toynbee regarded Eskimo civilization as arrested because it confronted a challenge that was too great to overcome and thus to produce a civilization that would not be characterized as arrested. Here is how Toynbee puts it:
“In addition to the two classes already noticed, developed civilizations and abortive civilizations, there is a third, which we must call arrested civilizations. It is the existence of civilizations which have kept alive but failed to grow that compels us to study the problem of growth; and our first step will be to collect and study the available specimens of civilizations of this category.”
Arnold Toynbee, A Study of History, Vol. 1., p. 164
“All these arrested civilizations have been immobilized in consequence of having achieved a tour de force. They are responses to challenges of an order of severity on the very borderline between the degree that affords stimulus to further development and the degree that entails defeat… we may add that four out of the five we have mentioned were in the end compelled to accept defeat. Only one of them, the Eskimo culture, is still maintaining itself.”
Arnold Toynbee, A Study of History, Vol. 1., p. 164-165
I do not necessarily disagree with this, though I wouldn’t formulate the idea of arrested civilizations in exactly the same way, but it is instructive and interesting. Where Toynbee goes seriously wrong is a couple of paragraphs further along:
“As for the Eskimos, their culture was a development of the North American Indian way of life specifically adapted to the conditions of life round the shores of the Arctic Ocean.”
Arnold Toynbee, A Study of History, Vol. 1., p. 165
Here Toynbee has gotten it exactly backward: it is not that the Eskimos were a development of North American Indian cultures, but that North American Indian cultures were a development of Eskimo culture — or, to be more precise, a development from a way of life that is the direct cultural ancestor of contemporary Eskimo life.
The order of derivation is important here because it refers to what is most fundamental in human experience over the longue durée, and this is largely the experience of Eskimo life, taking the latter in its broadest signification. For this reason I would not call Eskimo civilization “arrested” civilization but rather Proto-civilization.
Eskimo civilization is the ancestor of all human civilization, and in a world in which glaciation is the norm (as has been the case throughout the Quaternary Glaciation, which comprises the better part of the duration of human evolution) and brief, balmy inter-glacial periods have been the exception to the climatological rule, Eskimo life also represents the robust and sustainable way of human life to which homo sapiens can return time and again as the ice sheets advance and retreat.
Settled civilizations in an inter-glacial temperate zone — that climatological region most friendly to the growth of civilization that for Toynbee represents the norm for human society — would be fatally threatened by the arrival of a glacial maximum, but homo sapiens can always return to the ways of Eskimo life to weather the storm of severe climatological conditions. This makes of Eskimo civilization the source and the root of human life.
Had it not been for the game-changing emergence of industrial-technological civilization, this calculus would still hold good, but this unpredictable and unprecedented historical contingency has thrown everything into question, including verities that have shaped human life from its beginnings up until the Industrial Revolution only two hundred years ago.

As I have come to realize how much I enjoy documentaries of large scope, rather than waiting for them to fall me in a moment of serendipity, I now go looking for them. And so it is that I ordered Jacob Bronowski’s famous documentary, The Ascent of Man, from the library, and am now watching it.
The description of the series on the box, from Booklist, says that the series is, “an excellent resource for high-school and college students.” Well, it is much more than this. Like Clark’s Civilisation: A Personal View, Ronald’s Eyre‘s The Long Search, and Gwynne Dyer’s War, this work by Bronowski is not merely educative, as the reference to high-school and college students seems to suggest, but it takes a definite point of view, a personal point of view. This stands in the best tradition of engaged scholarship and academic freedom.
I recently wrote of Clark’s Civilisation that he maintains a number of theses throughout his presentation, and the same is true of Bronowski. These documentaries are not merely showing us pretty pictures and telling us what once happened long ago, they are making arguments, and if you aren’t aware of that an argument is being made, and that others have argued to the contrary, you will miss a lot that is valuable in these presentations. It is only thoughtlessness — and thoughtlessness is the intellectual equivalent of carelessness — that would condescend to identify these arguments as mere “resource for high-school and college students.”
I am reminded, in this context, of Bertrand Russell’s A History of Western Philosophy. There are a few institutionalized philosophers who use this book as a classroom text. If you already know a good deal of philosophy, Russell’s survey is a very funny review, but if you do not know philosophy and attempt to learn it from Russell’s book, you will end up with some serious misapprehensions of the discipline. Russell’s history is a wonderful book, but is adopts a definite point of view, and as such sets its up in opposition to other points of view. Copleston’s history is much more detailed and closer to being objective, and Passmore’s history, though it only covers the nineteenth and twentieth centuries, is better than either, though it too has a point of view.
So it is with Bronowski on the history of science and Clark on the history of civilization: these are not “textbooks,” though there is much to be learned from them. With justification, both television series are subtitled, “A Personal View.” I find much of value in these personal views; that is in fact why I seek them out. It is interesting to know that Bronowski’s science series was conceived in conscious counterpoint to Clark’s series on civilization. In an interview with Sir David Attenborough that is included on the Civilisation DVD, the latter reveals how BBC 2 controller Aubrey Singer was castigated for putting the arts “first” in having Clark’s Civilisation as the first large, multi-part documentary on the network.
While Bronowski’s series was undertaken in conscious contradistinction to Clark’s Civilisation, as a science counterpoint to Clark’s arts perspective, there are in fact many similarities and continuities between the two, and both maintain similar theses, though Bronowski’s are formulated in a much longer time frame. I sharply disagree with many of Bronowski’s central theses, but I will leave any criticisms for another time. For the moment I would like to focus on what I find most valuable in Bronowski’s perspective.
Bronowski is very much a practitioner of the longue durée, though he is not an historian per se, and not a structuralist. But Bronowski’s long term perspective on time adds up to more than the sum of its extended parts. The absolute quantity of history taken in my Bronowski’s perspective ultimately has qualitative consequences for the conception of history given exposition by Bronowski. I enthusiastically approve of this, as this is exactly what I have been trying to get at in what I have come to call metaphysical history (and which I formerly called Integral History).
Comparing Bronowski and Clark on history, Bronowski’s reflections are the more radical. Let me try to explain what I mean by that, and it won’t be easy. We are so familiar with the political use of “radical” that we have lost the larger, more comprehensive meaning of the term. The sense of “radical” to which I am appealing has nothing to do with waving signs in the street or calling for the overthrow of government. “Radical” in a philosophical sense is something beyond the most intemperate demands of the political radical, and therefore in a sense even more radical.
To be radical is to go to the root. It is to get at the fons et origo of things. The political radical wants to get at the root of a political problem by eliminating an old and compromised society and effecting a root-and-branch reconstruction of society. Thus the political sense of being radical is a specialized sense of “radical.” A comprehensive conception of what it is to be radical, an extended sense of radical not restricted to any one concern or discipline, is ultimately metaphysical. To be metaphysically radical is to attempt to get at the root of the world.
Husserl throughout his works of phenomenology, emphasized the radical nature of phenomenological reflection. Husserl is trying to get at the root of things, and that is what makes his thought radical. Throughout his Cartesian Meditations, for example, he calls for philosophical radicalism. This is a consistent theme in Husserl, and here is a characteristic passage:
“In recent times the longing for a fully alive philosophy has led to many a renaissance. Must not the only fruitful renaissance be the one that reawakens the impulse of the Cartesian Meditations: not to adopt their content but, in not doing so, to renew with greater intensity the radicalness of their spirit, the radicalness of self-responsibility, to make that radicalness true for the first time by enhancing it to the last degree, to uncover thereby for the first time the genuine sense of the necessary regress to the ego, and consequently to overcome the hidden but already felt naïveté of earlier philosophizing?”
Edmund Husserl, Cartesian Meditations, The Hague: Martinus Nijhoff, 1960, Introduction, section 2, “The necessity of a radical new beginning of philosophy,” p. 6
I see Bronowski’s perspective as a scientific radicalism that is closely parallel to Husserl’s philosophical radicalism. Both forms of radicalism are metaphysical, and seek to get at the root of reality itself.
One practical example of this is that early in his television series (in the second episode, I think — I don’t yet know this as well as Clark’s Civilisation, which I nearly have memorized) Bronowski refers to “civilization as we know it” as being 12,000 years old, which means that he is identifying civilization with the Neolithic Agricultural Revolution and the emergence of settled life in villages and eventually cities. I have made this claim myself, in this forum, though it is not typical to date civilization in this way. Also early in the series Bronowski says, “nature, i.e., evolution.” This reminds me of the evolutionary bluntness of JFK in his “sea” speech, which I mentioned in my post Inaugural Special Edition.
The evolutionary honesty of Bronowski is presently under attack by anti-scientific crackpots from the right. But Bronowski is equally honest about human adaptive radiation, openly discussing the adaption of various ethnic groups (formerly called “races”) to the different environments into which they migrated, and this is a position that is presently under attack my anti-scientific crackpots on the left. It is, in part, this admirable indifference to political implications that makes Bronowski’s position radical in the best sense of the term.
New forms of dishonesty and humbug are always emerging from human history, as men twist and turn their minds in an anti-heroic effort not to see things as they are, and it often requires considerable effort — a radical effort like that of Husserl or Bronowski — to transcend these ingenious efforts at self-deception. Such an effort is difficult, but the reward is correspondingly great.

A truly free market is an ideal that has probably never been realized in practice. In the earliest economies of prehistory, before there were national boundaries and formal taxes and tariffs to distort the way the market functions, there was nothing like capital per se, and not really a functioning formal economy to speak of. There was economic activity, but of a sort that might well be incommensurable when compared to what we know today as economic activity. In any case, it is worth mentioning prehistory in this context, as whatever economy did exist was probably the closet approximation to a free market that the world as known. The growth of political and social institutions (what Freud thought of and Marcuse called repressive ) were not only psychologically and socially repressive, but also commercially repressive. And things have only gotten worse with time.
By the time we reach the stage in history at which there is a formal economy and such a thing as capital, there are an abundance of restrictions, both formal and informal, to any market functioning freely. And there are many markets to keep in mind: not only different markets in different geographical locations, but markets in goods, markets in services, the labor market, and, of course, the market for money. People like to say that money makes the world go round, and that if you have enough money you can get away with just about anything, but the freedom of money is just as compromised by political and social restrictions, both formal and informal, as any other sector of the economy.
I have several times quoted the famous passage from the Communist Manifesto in which Marx called free trade “that single, unconscionable freedom.” (for example, in Shocking Revelations at the Institute for New Economic Thinking) As I have pointed out elsewhere how silly this assertion is I will not belabor the point here, but I will point out that Marx calls free trade, and thinks of free trade, as a single freedom. It is not. A free market would ideally embody many freedoms, and that is one reason why free trade remains an unrealized ideal: no society has yet been sufficiently free that it embodies all of the freedoms in a sufficiently robust form that we could say that the markets were truly free.
Yesterday in Ratepayers: Everyday Life in Late Industrialized Capitalism I emphasized the choice that consumers have in spending their money, and this choice has evolved into frankly deceptive practices on the part of business in trying to attract and retain ratepayers. This commercial dishonesty represents an informal constraint on freedom that probably could never be eliminated. We can, however, work to reduce formal constraints on freedom of trade, though in doing so, and in not addressing the informal constraints upon trade, we tacitly recognize that the market freedom that we are working toward is still far from ideal, and even far from optimal.
Besides the freedom of the consumer to spend money as he or she likes, there is also the freedom of capital, which can be formulated either in terms of the freedom of investors to spend money as they like, or simply in terms of allowing the market to determine allocation of capital. when we think of it in these latter terms, and also keeping in mind the distinction between formal and informal constraints upon free action, we again see how far markets are from being free. It is almost impossible to imagine a society in which markets purely determine the allocation of capital. In almost all societies, capital is controlled by the most powerful and influential sectors of society, and these sectors of society make determination partly on the basis of expected return on investment, but probably also just as much on the basis of who they know, and what they know (and the latter is the function of the former).
Given that one of the responses to informal constraints upon free markets has been further regulation, and therefore further interference in ideal market freedom, I am not optimistic about the realization of ideal market freedom any time soon, though I remain confident that the fickleness of the consumer will continue to confound the experts as consumers choose to spend their money in ways that were not predicted. As I implied yesterday, no one can predict what product or service will be in such demand that teenagers will work at after school jobs in order to acquire the next “hot” lifestyle accoutrement. In other words, ratepayers are lucrative, but also elusive.

Several media sources today reported on an upcoming article in the journal Proceedings of the National Academy of Sciences in which it is argued that ancient ostrich egg shells etched with markings constitute the earliest record of symbolic cognition. The shell fragments were found at the Diepkloof Rock Shelter in Western Cape in South Africa, and are dated between 55,000 and 65,000 years ago. Not far away, at the Blombos Cave on the Southern Cape, also in South Africa, etched abstract designs have been discovered earlier that may be as old as 100,000 years.
This paper is apparently getting a lot of attention because of the claim of the researchers that the markings are not merely decorative, but represent a graphic form of communication and therefore early evidence of symbolic thinking and language. As the paper is not yet available, and one must rely on the news reports, it is probably better to withhold any judgment, but even though I am skeptical of the claim of the etchings being evidence of symbolic thinking they are still of the greatest interest.
Part of the question comes down to what constitutes symbolic thinking. I suspect that the markings are decorative rather than a means to convey information, but their decorative character, if such it is, does not make it less important to the history of human thought. I think it would be extraordinarily difficult to establish these markings are symbolic communication in any robustly scientific sense, but that does not mean that our early ancestors who created these objets d’art did not have language. I strongly suspect that a sophisticated spoken language emerged early in the history of anatomically modern man, but that it was not converted into written symbols until much, much later. Obviously, the writers of the article have a different view on this matter.
In Ideas Again I mentioned listening to the lectures “Ideas that Have Shaped Mankind” by Felipe Fernández-Armesto, who maintained (perhaps for a certain shock value) that the oldest idea may that be that of cannibalism. I sympathize with Fernández-Armesto’s approach, but I don’t think that cannibalism is the oldest human idea. However, one could make the convincing case that decoration is the oldest human idea. Or, if you prefer, we could say that art is the oldest human idea. Taking delight in the product of one’s own hands, and then systematically seeking to increase one’s delight by distributing the product of one’s hands as widely as possible, is a quintessentially human idea, and it may be the oldest. Does art constitute symbolic thinking? There is a sense in which it does, but it is a different kind of symbolic thinking that written language.
These fragments of decorated ostrich egg shells from the Diepkloof Rock Shelter, and the similar designs from Blombos Cave that are even earlier, not only are among the earliest artifacts of human beings, they are so old that they nearly coincide with the emergence of anatomically modern man himself, homo sapiens sapiens, who dates back to approximately the same time frame as these artifacts. It would seem that mankind and his art emerged more or less simultaneously in natural history. If this is the case, we could define man in terms of his art.

There is an interesting article on the BBC about the recreation of early ocean-going canoe voyages in the south Pacific, Yap revives ancient art of star sailing. I find this a fascinating example of experimental archaeology.
Experimental archaeology really runs the gamut. Here’s an informal definition of experimental archaeology that I found at the Archaeology Expert website:
Experimental archaeology is one of the very practical methods of archaeological interpretation. It is a living analytical process used to re-create aspects in part or in whole, of ancient societies in order to test hypotheses or proposed interpretations and assumptions about that society.
The BBC article referenced above focuses on the recovery of the cultural tradition represented by ocean-going outrigger canoes and celestial navigation for Yap island, but it could still be considered a form of experimental archaeology. As I said, experimental archaeology runs the gamut. There are serious studies and there are media stunts and there are the many European open-air museums (among my favorite places to visit). Open-air museums are sometimes maintained in part to reconstruct the life of the past and also in part as an entertainment for tourists.
A few years ago when so-called “reality TV” was getting its start, public television jumped on the bandwagon and produced several series — some trivial, others riveting — that were essentially documentaries of experimental archaeology. I watched several of these with great interest.
Perhaps the most famous example of experimental archaeology in our time is the work of Thor Heyerdahl in recreating ancient sea-going vessels and recreating long distance voyages with them in order to demonstrate the possibility of his archaeological theories that were rejected by the mainstream historical and archaeological community. The Thor Heyerdahl Kon-Tiki museum in Oslo is absolutely fascinating. I visited it more-or-less on a whim a few years ago in Norway, not expecting it to be all that interesting, but I ended up staying for several hours. I heartily recommend it.
Voyages such as are made by the Yap islanders and those recreated by Thor Heyerdahl are crucial to our understanding of the last phase of human expansion and migration (which is not yet complete, but continues in an altered form even today). It is likely that the South Pacific was the last place on earth inhabited and settled by humanity. Perhaps if we had known the paradise that awaited us there, we might have gotten there sooner, but when men sail into the unknown they never know what they will find or whether they will ever return. And if they do not return, those who did not go do not know if they were lost or whether they found a better place and stayed there.
The Pacific is an enormous ocean. It was not crossed by European vessels until Magellan’s expedition (though Magellan died before the circumnavigation was completed and did not live to see the Pacific crossing). To set out upon the Pacific in nothing more than a canoe, and to live to tell the tale, is a feat equal to any in the history of human achievement. Whether we should think of this as a moment in natural history or a moment in human or cultural history is not clear. I don’t know what to call it myself, since the settlement of the South Pacific by ocean going canoes, while it constituted the last stage of the globalization of the human species, still took place in prehistory.
