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.
