In, “Some Conclusive Reasons Against ‘Conclusive Reasons’”, Pappas and Swain have criticized Dretske’s theory that conclusive reasons are necessary for knowledge. In their view this condition is too strong. They attempt to show this by means of two purported counterexamples: the cup-hologram case and the generator case. This paper defends Dretske’s analysis against these challenges.

In this paper I propose a teleological account of epistemic reasons. In recent years, the main challenge for any such account has been to explicate a sense in which epistemic reasons depend on the value of epistemic properties. I argue that while epistemic reasons do not directly depend on the value of epistemic properties, they depend on a different class of reasons which are value based in a direct sense, namely reasons to form beliefs about certain propositions or subject matters. In short, S has an epistemic reason to believe that p if and only if S is such that if S has reason to form a belief about p, then S ought to believe that p. I then propose a teleological explanation of this relationship. It is also shown how the proposal can avoid various subsidiary objections commonly thought to riddle the teleological account.

Can we give a uniform account of reasons in the three spheres of action, belief, and sentiment? Are reasons in these three spheres genuinely distinct, or are they in some way reducible to less than three? What kind of knowledge do we have of reasons – and what is it that we know? Some basic problems in philosophy depend on our answers to these questions.

Though one believes that P is true, one can have reasons for thinking it false. Yet, it seems that one cannot know that P is true and (still) have reasons for thinking it false. Why is this so? What feature of knowledge (or of reasons) precludes having reasons or evidence to believe (true) what you know to be false? If the connection between reasons (evidence) and what one believes is expressible as a probability relation, it would seem that the only satisfactory explanation of this fact is that when one knows that P is true, the reasons or evidence one has in support of P are such as to confer upon P the probability of 1. It is shown by an application of Bayes' Theorem that any value smaller than 1 would permit having reasons to believe what one knows to be false. Hence, it would seem that knowledge requires conclusive reasons to believe (if reasons or evidence is required at all).

As Alan Wood has recently pointed out, there is "a long and strong philosophical traditionthat parcels out cognitive tasks to human faculties in such a way that belief is assigned to the will".1 Such an approach lends itself to addressing the ethics of belief as an extension of practical ethics. It also lends itself to a treatment of reasons for belief that is an extension of its treatment of reasons for action, for our awareness of reasons for action provides the framework within which we make reasonable, and hence morally acceptable, choices. One who holds that agents can make reasonable (and unreasonable) choices in relation to our "cognitive tasks" should, then, also expect that those choices occur in a framework established by our apprehension of reasons for belief. This paper seeks to articulate what an extension of an account of reasons for actions to an account of reasons for belief would look like. I also make some suggestions as to how the ethics of belief might parallel practical ethics.

In this paper I argue against the stronger of the two views concerning the right and wrong kind of reasons for belief, i.e. the view that the only genuine normative reasons for belief are evidential. The project in this paper is primarily negative, but with an ultimately positive aim. That aim is to leave room for the possibility that there are genuine pragmatic reasons for belief. Work is required to make room for this view, because evidentialism of a strict variety remains the default view in much of the debate concerning normative reasons for belief. Strict versions of evidentialism are inconsistent with the view that there are genuine pragmatic reasons for belief.

In this lucid portrayal of human behavior, Fred Dretske provides an original account of the way reasons function in the causal explanation of behavior.

The paper offers an explanation of what reasons for belief are, following Paul Grice in focusing on the roles of reasons in the goal-directed activity of reasoning. Reasons are particularly salient considerations that we use as indicators of the truth of beliefs and candidates for belief. Reasons are distinguished from enabling conditions by being things that we should be able to attend to in the course of our reasoning, and in assessing how well our beliefs are supported. The final section argues that epistemic virtues have a role in enabling us to identify reasons and explores this by reference to the example of being observant.

This paper poses a puzzle concerning a broadly held view about normative reasons for belief: evidentialism. Evidentialism is the highly intuitive view that the only normative reasons for belief are evidential reasons. I shall argue that in certain circumstances, evidentialism is unable to generate the correct reasons for belief; these reasons can only be provided by other kinds of epistemic reasons apart from evidential ones. I am not arguing that reasons in ordinary cases for belief are non-evidential, but that evidentialism is too narrow an account of normative reasons for belief to serve as a complete theory of epistemic reasons.
