I defend the view that justified belief is preferable to plain belief only because the former enhances the likelihood that the belief is true: call that sort of justification truth-linked. A collection of philosophical theories either state outright that this is not so, imply it via other doctrines, or adopt a notion of truth that renders the link innocuous. The discussion proceeds as follows. Issues and various positions are outlined, and needed qualifications are entered (parts I-III). We then note general (...) shortcomings of all views rejecting the truth-link, and critically examine a powerful thought experiment underlying the rejection (part IV). In the final sections we explore two other challenges to the truth-link. First (part V), we consider forms of idealized justification theory that would imply the independence of justification from the relevant sort of truth conduciveness; next (part VI) we investigate a view, Pragmatism, which maintains that epistemic justification is sanctioned by ends other than a tendency towards truth.

We introduce a distinction, unnoticed in the literature, between four varieties of objective Bayesianism. What we call ' strong objective Bayesianism' is characterized by two claims, that all scientific inference is 'logical' and that, given the same background information two agents will ascribe a unique probability to their priors. We think that neither of these claims can be sustained; in this sense, they are 'dogmatic'. The first fails to recognize that some scientific inference, in particular that concerning evidential relations, is (...) not (in the appropriate sense) logical, the second fails to provide a non-question-begging account of 'same background information'. We urge that a suitably objective Bayesian account of scientific inference does not require either of the claims. Finally, we argue that Bayesianism needs to be fine-grained in the same way that Bayesians fine-grain their beliefs. (shrink)
