 Rules for the Knowledge Operator

Show Summary Details

Preview

This chapter examines the idea that the logical principles governing the knowledge operator are the root cause of the paradox. There are two such principles: the first is that knowledge implies truth, and the second is that knowledge distributes over conjunction, so that knowledge of a conjunction constitutes knowledge of the conjuncts. It is argued that the paradox cannot be avoided by questioning these principles.

Keywords: knowledge operator; truth; conjunction; paradox; Fred Dretske; Robert Nozick; closure
