Overcoming Epistemology
Epistemology, once the pride of modern philosophy, seems in a bad way these days. Fifty years ago, during the heyday of logical empiricism, which was not only a powerful movement in philosophy but also immensely influential in social science, it seemed as though the very center of philosophy was its theory of knowledge. That was clearly philosophyâs main contribution to a scientific culture. Science went ahead and gathered knowledge; philosophical reflection concerned the validity of claims to knowledge. The preeminence of epistemology explains a phenomenon like Karl Popper. On the strength of his reputation as a theorist of scientific knowledge, he could obtain a hearing for his intemperate views about famous philosophers of the tradition, which bore a rather distant relation to the truth.1 It is reminiscent of a parallel phenomenon in the arts, whereby the political opinions of a great performer or writer are often listened to with an attention and respect that their intrinsic worth hardly commands.
Of course, all this was only true of the Anglo-Saxon world. On the Continent the challenge to the epistemological tradition was already in full swing. Heidegger and Merleau-Ponty had a wide influence. It would be too simple to say that this skeptical stance has now spread to the English-speaking world. Rather it seems true to say that epistemology has come under more intensive critical scrutiny in both cultures. In France, the generation of structuralists and poststructuralists was if anything even more alienated from this whole manner of thinking than Merleau-Ponty had been. In England and America, the arguments of both generations of continental thinkers have begun to have an impact. The publication of Richard Rortyâs influential Philosophy and the Mirror of Nature (1979) helped both to crystallize and to accelerate a trend toward the repudiation of the whole epistemological enterprise.
In some circles it is becoming a new orthodoxy that the whole enterprise from Descartes, through Locke and Kant, and pursued by various nineteenth- and twentieth-century succession movements, was a mistake. What is becoming less and less clear, however, is what exactly it means to overcome the epistemological standpoint or to repudiate the enterprise. Just what is one trying to deny?
Rortyâs book seems to offer a clear and plausible answer. The heart of the old epistemology was the belief in a foundational enterprise.2 What the positive sciences needed to complete them, on this view, was a rigorous discipline that could check the credentials of all truth claims. An alleged science could be valid only if its findings met this test; otherwise it rested on sand. Epistemology would ultimately make clear just what made knowledge claims valid, and what ultimate degree of validity they could lay claim to. (One could, of course, come up with a rather pessimistic, skeptical answer to the latter question. Epistemology was not necessarily a rationalist enterprise. Indeed, its last great defenders were and are empiricists.)
In practice, epistemologists took their cue from what they identified as the successful sciences of their day, all the way from Descartesâs infatuation with mathematics to the contemporary vogue for reduction to physics. But the actual foundational science was not itself supposed to be dependent on any of the empirical sciences, and this obviously on pain of a circularity that would sacrifice its foundational character. Arguments about the source of valid knowledge claims were not supposed to be empirical.
If we follow this description, then it is clear what overcoming epistemology has to mean. It will mean abandoning foundationalism. On this view, Quine would figure among the prominent leaders of this new philosophical turn, since he proposes to ânaturalizeâ epistemology, that is, deprive it of its a priori status and consider it as one science among others, one of many mutually interacting departments of our picture of the world.3 And so Rorty does seem to consider him, albeit with some reservations.4
But there is a wider conception of the epistemological tradition, from whose viewpoint this last would be a rather grotesque judgment. This is the interpretation that focuses not so much on foundationalism as on the understanding of knowledge that made it possible. If I had to sum up this understanding in a single formula, it would be that knowledge is to be seen as correct representation of an independent reality. In its original form, it saw knowledge as the inner depiction of an outer reality.5
The reason why some thinkers prefer to focus on this interpretation, rather than merely on the foundationalist ambitions that are ultimately (as Quine has shown) detachable from it, is that it is bound up with very influential and often not fully articulated notions about science and about the nature of human agency. Through these it connects with certain central moral and spiritual ideas of the modern age. If oneâs aim is, in challenging the primacy of epistemology, to challenge these ideas as well, then one has to take it up in this widerâor deeperâfocus, and not simply show the vanity of the foundational enterprise.
I would like now to trace some of these connections. One of them is evident: the link between the representational conception and the new, mechanistic science of the seventeenth century. This is, in fact, twofold. On one side, the mechanization of the world picture undermined the previously dominant understanding of knowledge and thus paved the way for the modern view. The most important traditional view was Aristotleâs, according to which when we come to know something, the mind (nous) becomes one with the object of thought.6 Of course this is not to say that they become materially the same thing; rather, mind and object are informed by the same eidos.7 Here was a conception quite different from the representational model, even though some of the things Aristotle said could be construed as supporting the latter. The basic bent of Aristotleâs model could much better be described as participational: being informed by the same eidos, the mind participates in the being of the known object, rather than simply depicting it.
But this theory totally depends on the philosophy of Forms. Once we no longer explain the way things are in terms of the species that inform them, this conception of knowledge is untenable and rapidly becomes almost unintelligible. We have great difficulty in understanding it today. The representational view canâthen appear as the only available alternative.
This is the negative connection between mechanism and modern epistemology. The positive one obtrudes as soon as we attempt to explain our knowing activity itself in mechanistic terms. The key to this is obviously perception, and if we see it as another process in a mechanistic universe, we have to construe it as involving as a crucial component the passive reception of impressions from the external world. Knowledge then hangs on a certain relation holding between what is âout thereâ and certain inner states that this external reality causes in us. This construal, valid for Locke, applies just as much to the latest artificial-intelligence models of thinking. It is one of the mainsprings of the epistemological tradition.
The epistemological construal is, then, an understanding of knowledge that fits well with modern mechanistic science. This is one of its great strengths, and certainly it contributes to the present vogue of computer-based models of the mind. But thatâs not all this construal has going for it. It is in fact heavily overdetermined. For the representational view was also powered by the new ideals of science, and new conceptions of the excellence of thought, that arose at the same time.
This connection was central to Descartesâs philosophy. It was one of his leading ideas that science, or real knowledge, does not simply consist of a congruence between ideas in the mind and the reality outside. If the object of my musings happens to coincide with real events in the world, this doesnât give me knowledge of them. The congruence has to come about through a reliable method, generating well-founded confidence. Science requires certainty, and this can only be based on that undeniable clarity Descartes called evidence. âToute science est une connaissance certaine et Ă©vidente,â runs the opening sentence of the second rule in Rules for the Direction of the Mind.
Now certainty is something the mind has to generate for itself. It requires a reflexive turn, where instead of simply trusting the opinions you have acquired through your upbringing, you examine their foundation, which is ultimately to be found in your own mind. Of course, the theme that the sage has to turn away from merely current opinion, and make a more rigorous examination that leads him to science, is a very old one, going back at least to Socrates and Plato. But what is different with Descartes is the reflexive nature of this turn. The seeker after science is not directed away from shifting and uncertain opinion toward the order of the unchanging, as with Plato, but rather within, to the contents of his own mind. These have to be carefully distinguished both from external reality and from their illusory localizations in the body, so that then the correct issue of science, that is, of certainty, can be posedâthe issue of the correspondence of idea to reality, which Descartes raises and then disposes of through the supposition of the malin genie and the proof of his negation, the veracious God.
The confidence that underlies this whole operation is that certainty is something we can generate for ourselves, by ordering our thoughts correctlyâaccording to clear and distinct connections. This confidence is in a sense independent of the positive outcome of Descartesâs argument to the existence of a veracious God, the guarantor of our science. The very fact of reflexive clarity is bound to improve our epistemic position, as long as knowledge is understood representationally. Even if we couldnât prove that the malin gĂ©nie doesnât exist, Descartes would still be in a better position than the rest of us unreflecting minds, because he would have measured the full degree of uncertainty that hangs over all our beliefs about the world, and clearly separated out our undeniable belief in ourselves.
Descartes is thus the originator of the modern notion that certainty is the child of reflexive clarity, or the examination of our own ideas in abstraction from what they ârepresent,â which has exercised such a powerful influence on western culture, way beyond those who share his confidence in the power of argument to prove strong theses about external reality. Locke and Hume follow in the same path, although Hume goes about as far in the direction of skepticism as any modern has. Still, it remains true for Hume that we purge ourselves of our false confidence in our too-hasty extrapolations by focusing attention on their origin in our ideas. It is there that we see, for instance, that our beliefs in causation are based on nothing more than constant conjunction, that the self is nothing but a bundle of impressions, and so on.
This reflexive turn, which first took form in the seventeenth- and eighteenth-century âway of ideas,â is indissolubly linked to modern representational epistemology. One might say it presupposes this construal of knowledge. If Plato or Aristotle were right, the road to certainty couldnât be inwardâindeed, the very notion of certainty would be different: defined more in terms of the kinds of being that admit of it, rather than by the ordering of our thoughts. But I believe there is also a motivational connection in the other direction: the ideal of self-given certainty is a strong incentive to construe knowledge in such a way that our thought about the real can be distinguished from its objects and examined on its own. And this incentive has long outlived the original way of ideas. Even in an age when we no longer want to talk of Lockean âideasâ or of âsense data,â where the representational view is reconstrued in terms of linguistic representations or bodily states (and these are perhaps not genuine alternatives), there is still a strong draw toward distinguishing and mapping the formal operations of our thinking. In certain circles it would seem that an almost boundless confidence is placed in the defining of formal relations as a way of achieving clarity and certainty about our thinking, be it in the (mis)application of rational choice theory to ethical problems or in the great popularity of computer models of the mind.
The latter is an excellent example of what I called the âoverdeterminationâ of the epistemological construal. The plausibility of the computer as a model of thinking comes partly from the fact that it is a machine, hence living âproofâ that materialism can accommodate explanations in terms of intelligent performance; but partly too it comes from the widespread faith that our intelligent performances are ultimately to be understood in terms of formal operations. The computer, it has been said, is a âsyntactic engine.â8 A controversy rages over precisely this point. The most perspicuous critics of the runaway enthusiasm with the computer model, such as Hubert Dreyfus,9 tirelessly point out how implausible it is to understand certain of our intelligent performances in terms of a formal calculus, including our most common everyday actions, such as making our way around rooms, streets, and gardens or picking up and manipulating the objects we use. But the great difficulties that computer simulations have encountered in this area donât seem to have dimmed the enthusiasm of real believers in the model. It is as though they had been vouchsafed some revelation a priori that it must all be done by formal calculi. Now this revelation, I submit, comes from the depths of our modern culture and the epistemological model anchored in it, whose strength is based not just on its affinity to mechanistic science but also on its congruence to the powerful ideal of reflexive, self-given certainty.
For this has to be understood as something like a moral ideal. The power of this ideal can be sensed in the following passage from Husserlâs Cartesian Meditations (1929), all the more significanât in that Husserl had already broken with some of the main theses of the epistemological tradition. He asks in the first meditation whether the âhopelessnessâ of the current philosophical predicament doesnât spring from our having abandoned Descartesâs original emphasis on self-responsibility:
Sollte die vermeintlich ĂŒberspannte Forderung einer auf letzte erdenkliche Vorurteilslosigkeit abgestellten Philosophie, einer in wirklicher Autonomie aus letzten selbst erzeugten Evidenzen sich gestaltenden und sich von daher absolut selbstverantwortenden Philosophie nicht vielmehr zum Grundsinn echter Philosophie gehören?10
The ideal of self-responsibility is foundational to modern culture. It emerges not only in our picture of the growth of modern science through the heroism of the great scientist, standing against the opinion of his age on the basis of his own self-responsible certaintyâCopernicus, Galileo (he wobbled a bit before the Holy Office, but who can blame him?), Darwin, Freud. It is also closely linked to the modern ideal of freedom as self-autonomy, as the passage from Husserl implies. To be free in the modern sense is to be self-responsible, to rely on your own judgment, to find your purpose in yourself
And so the epistemological tradition is also intricated in a certain notion of freedom, and the dignity attaching to us in virtue of this. The theory of knowledge partly draws its strength from this connection. But, reciprocally, the ideal of freedom has also drawn strength from its sensed connection with the construal of knowledge seemingly favored by modern science. From this point of view it is fateful that this notion of freedom has been interpreted as involving certain key theses about the nature of the human agent; we might call them anthropological beliefs. Whether these are in fact inseparable from the modern aspiration to autonomy is an open question, and a very important one, to which I will return briefly later. But the three connected notions I want to mention here are closely connected historically with the epistemological construal.
The first is the picture of the subject as ideally disengaged, that is, as free and rational to the extent that he has fully distinguished himself from the natural and social worlds, so that his identity is no longer to be defined in terms of what lies outside him in these worlds. The second, which flows from this, is a punctual view of the self, ideally ready as free and rational to treat these worldsâand even some of the features of his own characterâinstrumentally, as subject to change and reorganizing in order the better to secure the welfare of himself and others. The third is the social ...
