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.
