Summary

Nozick's Philosophical Explanations (1981) is a wide-ranging philosophical work exploring knowledge, identity, free will, and the foundations of ethics through non-coercive philosophical argument.

Core Contribution

Nozick proposes a tracking theory of knowledge — S knows P if S's belief tracks the truth of P across possible worlds — and introduces the experience machine thought experiment; he argues philosophy should offer illuminating explanations rather than coercive proofs.

Key Spikes & Highlights

Tracking theory of knowledge (knowledge is a belief that tracks the truth — if P were false, you would not believe P; if P were true, you would)
Experience machine thought experiment (we choose not to plug in because we want to actually do things, not just have the experience of doing them)
Non-coercive philosophy (philosophical arguments should be illuminating, not knock-down proofs that compel assent)
Personal identity via closest continuer (personal identity is determined by which future person most closely continues your psychological states)
