Nozick analyzes fundamental issues, such as the identity of the self, knowledge and skepticism, free will, the foundations of ethics, and the meaning of life.

This paper considers the debate over how we attribute beliefs, desires, and other mental states to our fellows. Do we employ a theory of mind? Or do we use simulational brain mechanisms, but employ no theory? One point of dispute between these theories focuses upon our ability to have empathic knowledge of the mind of another. I consider whether an argument posed by Ravenscroft settles the debate in favor of Simulation Theory. I suggest that the consideration of empathy does not (...) settle the dispute. Then I look at recent results from false memory research and other research employing neural imaging. I suggest that new discoveries there may help shape the future of the empirical dimension of the debate. (shrink)

This book presents an attempt to develop a theory of knowledge and a philosophy of mind using ideas derived from the mathematical theory of communication developed by Claude Shannon. Information is seen as an objective commodity defined by the dependency relations between distinct events. Knowledge is then analyzed as information caused belief. Perception is the delivery of information in analog form for conceptual utilization by cognitive mechanisms. The final chapters attempt to develop a theory of meaning by viewing meaning as (...) a certain kind of information-carrying role. (shrink)

Tracking theories of knowledge are widely known to have the consequence that knowledge is not closed. Recent arguments by Vogel and Hawthorne claim both that there are no legitimate examples of knowledge without closure and that the costs of theories that deny closure are too great. This paper considers the tracking theories of Dretske and Nozick and the arguments by Vogel and Hawthorne. We reject the arguments of Vogel and Hawthorne and evaluate the costs of closure denial for tracking theories (...) of knowledge. (shrink)

Sven Bernecker presents an analysis of the concept of propositional (or factual) memory, and examines a number of metaphysical and epistemological issues crucial to the understanding of memory. -/- Bernecker argues that memory, unlike knowledge, implies neither belief nor justification. There are instances where memory, though hitting the mark of truth, succeeds in an epistemically defective way. This book shows that, contrary to received wisdom in epistemology, memory not only preserves epistemic features generated by other epistemic sources but also functions (...) as a source of justification and knowledge. According to the causal theory of memory argued for in this book, the dependence of memory states on past representations supports counterfactuals of the form: if the subject hadn't represented a given proposition in the past he wouldn't represent it in the present. The book argues for a version of content externalism whereupon the individuation of memory contents depends on relations the subject bears to his past physical or social environment. Moreover, Bernecker shows that memory doesn't require identity, but only similarity, of past and present attitudes and contents. The notion of content similarity is explicated in terms of the entailment relation. (shrink)

Closure is the epistemological thesis that if S knows that P and knows that P implies Q, then if S infers that Q, S knows that Q. Fred Dretske acknowledges that closure is plausible but contends that it should be rejected because it conflicts with the plausible thesis: Conclusive reasons (CR): S knows that P only if S believes P on the basis of conclusive reasons, i.e., reasons S wouldn‘t have if it weren‘t the case that P. Dretske develops an (...) analysis of knowing that centers on CR, and argues that the requirement undermines skepticism by implying the falsity of closure. We develop a Dretske-style analysis of knowing that incorporates CR, and we argue that this analysis not only accords with closure, but also implies it. In addition, we argue that the analysis accounts for the prima facie plausibility of closure-invoking skeptical arguments, and nonetheless implies that they are fallacious. If our arguments turn out to be sound, the acceptability of Dretske‘s analysis of knowing will be significantly enhanced by the fact that, despite implying closure, it undermines closure-based skepticism.

Much of contemporary epistemology proceeds on the assumption that tracking theories of knowledge, such as those of Dretske and Nozick, are dead. The word on the street is that Kripke and others killed these theories with their counterexamples, and that epistemology must move in a new direction as a result. In this paper we defend the tracking theories against purportedly deadly objections. We detect life in the tracking theories, despite what we perceive to be a premature burial.

A theory of occurrent factual memory is sketched out. The theory represents an alterative to the traditional theory in John L. Pollock’s Knowledge and Justification, in that it analyzes occurrently remembering that p without employing the notion of ostensible recollection that p. The latter notion, it is argued, can be understood in terms of occurrently believing (or being inclined to believe) that p. In defending his theory against nontraditional alternatives, Pollock employs arguments that conflict with his own principle of implicit (...) reasons. That principle, it is shown, sanctions cross-temporal justification of the sort presupposed by the alternative nontraditional theory. [CORRIGENDUM: Line 6 at the top of page 137 should read: memory, then if S occurrently remembers that p at t, then S, at t, has a justified (occurrent) belief that p such that (a) this belief that p constitutes, at t, S’s In lines 7–9 at the top of page 140, the sentence beginning with “For” and ending with “way” should be deleted, and in line 11 “fact” should be “face”.] .
