The notion of a reason often plays a central role in epistemological theories. Justification is often explained in terms of the having of appropriate reasons, and a variety of epistemological distinctions are most naturally explained, it seems, by adverting to reasons. This paper examines the extent to which we may, instead, make do without appeal to such a notion. It is argued that the extent to which the notion of a reason should play an important role in epistemological theorizing will depend on how our psychological theories of belief acquisition and belief change are best conceptualized.

This paper examines Laurence BonJour''s defense of internalism inThe Structure of Empirical Knowledge with an eye toward better understanding the issues which separate internalists from externalists. It is argued that BonJour''s Doxastic Presumption cannot play the role which is required of it to make his internalism work. It is further argued that BonJour''s internalism, and, indeed, all other internalisms, are motivated by a Cartesian view of an agent''s access to her own mental states. This Caretsian view is argued to be untenable, and, accordingly, so is internalism.

This paper describes and assesses a number of dispositions which are instrumental in allowing us to take on the opinions of others unselfconsciously. It is argued that these dispositions are in fact reliable in the environments in which they tend to come into play. In addition, it is argued that agents are, by their own lights, justified in the beliefs they arrive at as a result of these processes. Finally, these processes are argued to provide a basis for rejecting the claim that fixation of belief is radically holistic.

Jonathan Vogel has presented a disturbing problem for reliabilism. 1 Reliabilists claim that knowledge is reliably produced true belief. Reliabilism is, of course, a version of externalism, and on such a view, a knower need have no knowledge, no justified belief, indeed, no conception that his or her belief is reliably produced. It is the fact that the knower's true belief is reliably produced which makes it a case of knowledge, not any appreciation of this fact. But Vogel now argues that reliabilists will, by a process he calls ‘bootstrapping’, far too easily gain knowledge of the reliability of the processes by which their knowledge is produced. For the reliabilist, knowledge which should be difficult to come by is quite easily and trivially attainable, Vogel argues. And this, of course, seems to show a fundamental flaw in the reliabilist conception of knowledge.One solution to this puzzle is offered by van Cleve . Bootstrapping may seem unattractive, van Cleve claims, but only when we fail to consider the alternative. Any epistemological view which does not legitimate bootstrapping, he argues, will inevitably lead to scepticism. And if the choice is between bootstrapping and scepticism, van Cleve will happily accept bootstrapping.It would be nice, certainly, if we could avoid this unpalatable dilemma.Vogel's argument is disturbingly straightforward. Suppose that Roxanne gains knowledge that the gas tank in her car is full by looking at her gas gauge, and let us further suppose that Roxanne has no reason at all to believe that her gas gauge is reliable. As Vogel points out, reliabilists cannot object to these assumptions. Precisely because reliabilism is a version of externalism, reliabilists must allow that there are cases meeting these very conditions. That is, reliabilists must allow that one can gain knowledge by way of a …
