I begin by asking the meta-epistemological question, 'What is justification?', analogous to the meta-ethical question, 'What is rightness?' I introduce the possibility of non-cognitivist, naturalist, non-naturalist, and eliminativist answers in meta-epistemology,corresponding to those in meta-ethics. I devote special attention to the naturalistic hypothesis that epistemic justification is identical to probability, showing its antecedent plausibility. I argue that despite this plausibility, justification cannot be identical with probability, under the standard interpretation of the probability calculus, for the simple reason that justification can (...) increase indefinitely but probability cannot. I then propose an alternative model for prima facie justification, based on an analogy with Ross's account of prima facie obligation, arguing that this model illuminates the differences between justification and probability and, given the plausible assumption of epistemic pluralism, explains them as well.

Bertrand Russell famously disparaged Thomas Aquinas as having ‘little of the true philosophic spirit’, because ‘he does not, like the Platonic Socrates, set out to follow wherever the argument may lead.’ Like many of Russell's pronouncements, this is breathtakingly supercilious and unfair. Still, even an enthusiastic admirer of Aquinas may worry that there is something in it, that there is something wrong with religious ‘commitments’ in philosophy. I examine Russell's objection by comparing standards of permissibility in epistemology with standards of (...) permissibility in ethics, where these issues are better understood. I conclude that the epistemic standard behind Russell's criticism is no less contentious in epistemology than, say, direct utilitarianism is in ethics. (shrink)

Simon Blackburn has shown that there is an analogy between the problem of moral motivation in ethics (how can moral reasons move us?) and the problem of what we might call the power of logical reasons (how can logical reasons move us, what is the force of the 'logical must?'). In this paper, I explore further the parallel between the internalism problem in ethics and the problem of the power of logical reasons, and defend a version of psychologism about reasons, (...) although not one of the Humean form. I discuss two forms of cognitivism: (i) a pure cognitivism and 'hard' realism modelled after Dancy's parallel conception in ethics: when we grasp logical reasons we grasp facts, which are directly known to us; (ii) a Kantian form of cognitivism, based on the idea that compulsion by reason goes with the capacity of reflection. I argue that (i) is implausible, and that (ii) fails to meet the internalist requirement. One would then seem to be left with what Dancy calls, about practical reasoning, psychologism about reasons. I sketch what might be such a psychologism. But it fails to account for the objectivity of logical reasons. I argue that the relevant state here is a form of dispositional knowledge of logical reasons. (shrink)

Viewing moral scepticism as the rejection of objective desirabilities, inductive scepticism may be seen as the rejection of objective believabilities. Moral scepticism leads naturally to amoralism rather than subjectivism, and inductive scepticism undermines not our practices of induction but only a view about justification. The two scepticisms together amount to the adoption of a defensibly narrow, formal view of reason.
