The Concept of Knowledge
The Concept of Knowledge
In this essay, McGinn argues for a version of reliabilism, contending that a belief counts as knowledge just in case ‘it is produced by a method capable of yielding true beliefs in a range of relevant cases’. This view diverges from other versions of reliabilism, notably Robert Nozick's counter‐factionalist tracking theory, which, McGinn argues, ‘localizes the conditions for knowledge into a relation between the knower and a unique proposition’. Against this local analysis of propositional knowledge, McGinn presents a global reliabilism in which the notion of discrimination is basic. On McGinn's view, global reliability consists in a subject's capacity to distinguish the true from the false within a relevant class of propositions. McGinn concludes by considering the implications of his view for sceptical arguments—in particular, the claim that knowledge is not closed under known logical implication.
