There are two interrelated but distinct programs which go by the name evolutionary epistemology. One attempts to account for the characteristics of cognitive mechanisms in animals and humans by a straightforward extension of the biological theory of evolution to those aspects or traits of animals which are the biological substrates of cognitive activity, e.g., their brains, sensory systems, motor systems, etc. (EEM program). The other program attempts to account for the evaluation of ideas, scientific theories and culture in general by (...) using models and metaphors drawn from evolutionary biology (EET program). The paper begins by distinguishing the two programs and discussing the relationship between them. The next section addresses the metaphorical and analogical relationship between evolutionary epistemology and evolutionary biology. Section IV treats the question of the locus of the epistemological problem in the light of an evolutionary analysis. The key questions here involve the relationship between evolutionary epistemology and traditional epistemology and the legitimacy of evolutionary epistemology as epistemology. Section V examines the underlying ontological presuppositions and implications of evolutionary epistemology. Finally, section VI, which is merely the sketch of a problem, addresses the parallel between evolutionary epistemology and evolutionary ethics. (shrink)

In arguing a "role for history," Kuhn was proposing a naturalized philosophy of science. That, I argue, is the only viable approach to the philosophy of science. I begin by exhibiting the main general objections to a naturalistic approach. These objections, I suggest, are equally powerful against nonnaturalistic accounts. I review the failure of two nonnaturalistic approaches, methodological foundationism (Carnap, Reichenbach, and Popper) and metamethodology (Lakatos and Laudan). The correct response, I suggest, is to adopt an "evolutionary perspective." This perspective (...) is defended against one recent critic (Putnam). To argue the plausibility of a naturalistic approach, I next sketch a naturalistic account of theories and of theory choice. This account is then illustrated by the recent revolution in geology. In conclusion I return to Kuhn's question about the role of history in developing a naturalistic theory of science. (shrink)

Reichenbach's well-known distinction between the context of discovery and the context of justification has recently come under attack from several quarters. In this paper I attempt to reconsider the distinction and evaluate various recent criticisms of it. These criticisms fall into two main groups: those which directly challenge Reichenbach's distinction; and those which (I argue) indirectly but no less seriously challenge that distinction by rejecting the related distinction between psychology and epistemology, and defending the "naturalizing" of epistemology. I argue that (...) these recent criticisms fail, and that the distinction remains an important conceptual tool necessary for an adequate understanding of the way in which scientific claims purport to appropriately portray our natural environment.

The traditional views of science as the possessor of a special method, and as the epitome or apex of rationality, have come under severe challenges for a variety of historical, psychological, sociological, political, and philosophical reasons. As a result, many philosophers are either denying science its claim to rationality, or else casting about for a new account of its rationality. In this paper a defense of the traditional view is offered. It is argued that contemporary philosophical discussion regarding the rationality (...) of science is plagued by a failure to distinguish among three different questions, all taken to be "the" question of the rationality of science. Once these questions are delineated, it becomes possible to answer one of them in such a way that the traditional link between science's rationality and its method is reestablished--although the scientific method is itself given a non-traditional rendering. In short, it is argued that there is a feature of science which is appropriately characterized as its method; that this method does in fact secure science's rationality; and that science is therefore correctly construed as preeminently rational. It is suggested in addition that the philosophy of science is itself best seen as a primarily epistemological activity, and consequently that a correction from the excessively historicist conception of recent philosophy of science is in order.

If philosophers of science advise government on science policy, it will have to be from a descriptive theory of scientific validity taken as hypothetically normative, as in naturalized epistemology. While logical positivism denied any normative import for the practice of science, in the area of "operational definitions" it had an unfortunate influence in psychology and sociology, and one that persists in the accountability movement. Not all philosophy of science issues have implications for the justificatory practice of scientists. For example, both (...) anti-realists and realists condone scientific quarreling about unobserved particles. Many young philosophers of science are now contributing to a sociology of scientific validity which, taken in a hypothetically normative manner, will produce recommendations on science policy.
