From 1914 on Russell's epistemology was dominated by the attempt to show how we come by our knowledge of the external world. As he gradually became aware of the inadequacies of the "pure empiricist" approach, Russell realized that his program was viable only insofar as certain postulates of inference were allowed. In this paper I trace the development of the structural postulates from Analysis of Matter to Human Knowledge. The basic continuity of Russell's thought is established. Certain confusions implicit in the various formulations of the postulates are brought to light. Finally, it is argued that the viability of Russell's program rests on a larger number of independent postulates than he thought were needed. Some implications of Russell's work for current work in the philosophy of science are briefly sketched.

This paper draws a connection between recent developments in naturalized philosophy of science and the Buchanan research program in economics. Economic approaches in naturalized philosophy of science can be combined to form an economic philosophy of science. After giving an overview of some of these approaches, I lay out the fundamentals of the Buchanan research program. I argue that its main elements are a theory of interactions and a normative foundation in consensus which help to answer some important criticisms of economic philosophy of science.

Recently, connectionist models have been developed that seem to exhibit structuresensitive cognitive capacities without executing a program. This paper examines one such model and argues that it does execute a program. The argument proceeds by showing that what is essential to running a program is preserving the functional structure of the program. It has generally been assumed that this can only be done by systems possessing a certain temporalcausal organization. However, counterfactualpreserving functional architecture can be instantiated in other ways, for example geometrically, which are realizable by connectionist networks.

In spite of of its name, cognitive science is not yet a fully coherent and integrated science but rather a fairly loose coalition of largely independent disciplines, some descriptive and empirical (cognitive psychology, linguistics, neuroscience, cognitive anthropology), some speculative and foundational (philosophy), others both speculative and applied (artificial intelligence). What brought these disciplines together and still sustains their interdisciplinary cooperation is the dedication to explain, simulate and technically reproduce the workings of the human mind according to a distinct and rather well defined research program. This program has been so far the animating spirit and the integrative force in the formation and development of cognitive science. I will call it the 'core program.' Around the core program there is a much looser and less coherent outer paradigm, or set of paradigms, which historically has prepared the ground for the core program, to which the participating disciplines have contributed their insights, results and methods, and still do, and from which challenges to the core program have emerged and are likely to do so in the future.

The importance for realism of the concept of truthlikeness was first stressed by Popper. Popper himself not only mapped out a program for defining truthlikeness (in terms of falsity content and truth content) but produced the first definitions within this program. These were shown to be inadequate. But the program lingered on, and the most recent attempt to revive it is that of Newton-Smith. His attempt is a failure, not because of some minor defect or technical flaw in his particular account but rather because the program incorporates a fundamental flaw. However, realists need not despair. There already exists an entirely different program not subject to these criticisms.

Two major reasons feminists are concerned with science relate to science's social effects: that science can be a powerful ally in the struggle for equality for women; and that all too frequently science has been a generator and perpetuator of inequality. This concern with the social effects of science leads feminists to a different mode of appraising science from the purely epistemic one prized by most contemporary philosophers of science. The upshot, I suggest, is a new program for philosophy of science, a program for a socially responsible philosophy of science.

In this paper I argue that the program of L. Laudan et al for empirically testing historiographical philosophies of science ("the VPI program") does not succeed in providing a consistent naturalist program in philosophy of science. In particular, the VPI program endorses a nonnaturalist metamethodology that insists on a hypothetico-deductive structure to scientific testing. But hypothetico-deductivism seems to be both inadequate as an account of scientific theory testing in general and fundamentally at odds with most of the historiographic philosophies under test. I sketch an account of testing historiographic philosophies of science more consistent with the views about scientific testing of those philosophies and argue that such a program is neither viciously circular nor necessarily self-refuting.
