The KK thesis, proposed by philosophers David K. Lewis and others, refers to the idea that if a person knows a proposition \\( P \\), then they also know that they know \\( P \\). In formal terms, if \\( K \\) denotes knowledge, the KK thesis can be expressed as: \\\[ K(P) \\implies K(K(P)) \\\] This thesis raises interesting questions in epistemology about the nature of knowledge and self-knowledge.
