Experiments with young infants provide evidence for early-developing capacities to represent physical objects and to reason about object motion. Early physical reasoning accords with 2 constraints at the center of mature physical conceptions: continuity and solidity. It fails to accord with 2 constraints that may be peripheral to mature conceptions: gravity and inertia. These experiments suggest that cognition develops concurrently with perception and action and that development leads to the enrichment of conceptions around an unchanging core. The experiments challenge claims (...) that cognition develops on a foundation of perceptual or motor experience, that initial conceptions are inappropriate to the world, and that initial conceptions are abandoned or radically..

G e moore and ludwig wittgenstein were very different teachers, both because of their differing views on the nature and aims of philosophical investigation, and because of the differences in the way they thought, their educational backgrounds, and the kind of persons they were. this paper records experiences of the two philosophers as teachers and as personalities, and indicates the features of their teaching which stemmed from their views and from their personalities.

Does scepticism threaten our common sense picture of the world? Does it really undermine our deep-rooted certainties? Answers to these questions are offered through a comparative study of the epistemological work of two key figures in the history of analytic philosophy, G. E. Moore and Ludwig Wittgenstein.

This dissertation aims to construct a non-dogmatic defence of common sense. It tries to show why the absence of justification for the judgements of common sense, which the sceptic reveals, does not invalidate them.

This contribution to the topical collection presents an overview of my previous work in epistemology. Specifically, I review arguments for the claim that important skeptical arguments in the history of philosophy motivate externalism in epistemology. In effect, only externalist epistemologies can be anti-skeptical epistemologies. I also review motivations for adopting a virtue-theoretic account of epistemic normativity. Such an account, I argue, has considerable explanatory power regarding the nature, value and scope of knowledge. In addition, a virtue-theoretic account is tailor made (...) for externalism. In effect, it shows how externalist epistemologies can also be normative epistemologies. Finally, I review arguments in favor of a general framework for understanding the epistemology of testimony, and, in particular, the transmission of knowledge. The framework motivates anti-reductionism in the epistemology of testimony, as well as the common anti-reductionist theme that trust can be epistemically significant, as opposed to merely practically significant. The framework, I argue, also weds nicely to a virtue-theoretic account of epistemic normativity, and in doing so answers an important objection to virtue epistemology—that the view is overly individualistic.

Epistemic Angst offers a completely new solution to the ancient philosophical problem of radical skepticism—the challenge of explaining how it is possible to have knowledge of a world external to us. Duncan Pritchard argues that the key to resolving this puzzle is to realize that it is composed of two logically distinct problems, each requiring its own solution. He then puts forward solutions to both problems. To that end, he offers a new reading of Wittgenstein's account of the structure of (...) rational evaluation and demonstrates how this provides an elegant solution to one aspect of the skeptical problem. Pritchard also revisits the epistemological disjunctivist proposal that he developed in previous work and shows how it can effectively handle the other aspect of the problem. Finally, he argues that these two antiskeptical positions, while superficially in tension with each other, are not only compatible but also mutually supporting. The result is a comprehensive and distinctive resolution to the problem of radical skepticism, one that challenges many assumptions in contemporary epistemology. (shrink)

In Connectionism and the Philosophy of Psychology, Horgan and Tienson articulate and defend a new view of cognition.

I defend two theses here. First, I argue that at least many of the commitments that Wittgenstein identifies as “hinge commitments” are plausibly what cognitive psychology and artificial intelligence call “procedural knowledge.” Procedural knowledge can be implemented in cognitive systems in a variety of ways, and these modes of implementation, I argue, predict several properties of Wittgensteinian hinge commitments, including their functional profile, as well as other of their characteristic features. Second, I argue that thinking of hinge commitments as a (...) kind of procedural knowledge allows a unified virtue-theoretic treatment of the generation of knowledge, the transmission of knowledge, and Wittgensteinian “hinge knowledge.” This last thesis is noteworthy, in that Wittgenstein and his defenders have so far failed to offer any unified epistemology of hinge commitments and the knowledge that such commitments are supposed to make possible.
