In this paper I want to discuss two separate problems about memory, connected in that they both have to do with memory as a source or ground of knowledge.

Thoughts and other mental states are defined by their role in a functional system. Since it is easier to determine when we have knowledge than when reasoning has occurred, Gilbert Harman attempts to answer the latter question by seeing what assumptions about reasoning would best account for when we have knowledge and when not. He describes induction as inference to the best explanation, or more precisely as a modification of beliefs that seeks to minimize change and maximize explanatory coherence.

The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

One difference between traditional and contemporary nontraditional theories of memory is that the former would affirm, whereas the latter would deny, that a person can be correctly described as having remembered that p solely in virtue of having knowledge the certainty of which is grounded upon the person’s present remembering. I argue that there cannot be such a case, and that what may appear to be such a case—as presented in Don Locke’s book Memory—can be explicated by a contemporary nontraditional (...) theorist without making any concessions to the traditional theorist.

For cases in which to remember that p is to have (strict) nonbasic, unmixed memory knowledge that p; in which there is at most one prior time, t, from which one remembers; in which one knew at t that p; and in which there can arise a sensible question whether one remembers that p from t — a person, B, remembers that p from t if and only if: (1) There is a set of grounds a subset of which consists (...) of (i) only those grounds B has at both t and the present for B to be sure that p, and (ii) enough such grounds to make it reasonable at both t and the present for B to be sure that p (I call any such subset a set of “adequate original grounds dating from t”), and (2) there is no time prior to t such that B has a set of adequate original grounds dating from that time. The way in which the crucial terms in this explication are being used is explained. And the explication is defended by showing how it can deal with cases that are counterexamples to explications recently offered by Malcolm and by Munsat. (shrink)

This paper examines a leading traditional account of memory knowledge. (A “traditional” account of memory knowledge locates whatever positive justification there may be for the belief which constitutes that knowledge in a present memory-impression.) The paper (1) presents a pair of cases designed to show that Carl Ginet’s four-part defeasibility-type definition of memory knowledge that p is either too weak or too strong, and (2) suggests how these cases could be handled by one sort of non-traditional account.
