In some views, knowledge cannot exist except against the background of certain social practices. Thus, in Davidson's view, there are no beliefs, and thus no knowledge, except in creatures that use and interpret language. In other views, such as Brandom's, belief, and thus knowledge, cannot exist except in creatures that have a social practice of giving and asking for reasons. Finally, there are views in which it is possible to have beliefs without social practices, but it is not possible to have justified beliefs, and hence knowledge, without some relevant social practice, such as holding individuals responsible for the beliefs they have. These views are examined in detail. It is argued that knowledge does not require social practices of any sort whatsoever.

In Chapter Four, it is argued that coherence is evidence of truth. A sketch of a theory of approximate truth is developed in terms of the theory of reference outlined in Chapter Three, and this notion is put to work in showing that there is reason to believe that most of our beliefs are at least approximately true. It is then argued that coherence with approximately true beliefs, and thus the beliefs we have, is evidence of truth. ;In Chapter Three, the connection between the theory of knowledge and the theory of reference is explored. The relation between Russell's theory of knowledge and his theory of reference is discussed, and it is argued that Russell was quite correct in insisting that there be a close relationship between these two disciplines. A theory of reference is developed which parallels the causal theory of knowledge presented in Chapter One. This theory is a variant of the causal, or historical theory, presented by Donnellan, Kripke, Putnam and Boyd. ;In Chapter One, an outline of a causal theory of knowledge is presented. It is argued that knowledge is reliably produced true belief, and that a process is reliable just in case it tends to produce true beliefs in relevant actual, as well as counterfactual, situations. ;In Chapter Two, the implications of this account for the debate between foundationalists and coherence theorists is examined. It is argued that standard foundational and coherentist accounts of justification share a common false presupposition, that the proper account of justification must be apsychological. It is argued that by rejecting this presupposition and adopting a causal theory of knowledge, it is possible to develop a theory which contains many of the important grains of truth in both foundationalism and coherentism. ;In this thesis, a causal theory of knowledge is elaborated and its implications examined

This paper examines the source and content of epistemic norms. In virtue of what is it that epistemic norms have their normative force? A semantic approach to this question, due to Alvin Goldman, is examined and found unacceptable. Instead, accounts seeking to ground epistemic norms in our desires are argued to be most promising. All of these accounts make epistemic norms a variety of hypothetical imperative. It is argued that such an account may be offered, grounding our epistemic norms in desire, which nevertheless makes these imperatives universal. The account is contrasted with some recent work of Stephen Stich.

We often find that beliefs we hold are in conflict with the beliefs of epistemic peers, individuals who are just as intelligent, just as well-informed, and just as scrupulous in forming their beliefs as we are. Is it permissible to maintain our beliefs in the face of such disagreement? It is argued here that continued belief in these circumstances is not epistemically permissible, and that this has striking consequences for the practice of philosophy: we cannot reasonably hold on to our philosophical views.

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 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.

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.

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 …
