Free Will, Identity & the Self

Free Will Identity and the Self · Open board

The closing board of the Philosophy series. Every earlier board asked what you can know, what your mind is, whether machines can share it, how to reason and how to act; this one turns the question back on whoever has been asking it, and loops back to What Is Knowledge?.

Before you start. The last lesson, on ethics, gave you three tests for whether an act is right: does it produce good outcomes, does it follow the right rule, does it come from good character (Ethics & the Good Life). This lesson asks about whoever applies those tests: were they ever free to choose, are they the same person who chose before, and is there a “them” doing the choosing at all.

The idea in 30 seconds

Determinism says every choice was fixed in advance; a choice with no cause at all wouldn’t be yours either - that’s the vise nobody has cleanly escaped.
Compatibilism escapes it by changing the question: call an act free when it flows from your own character and reasons, not when it was somehow uncaused.
Personal identity has the shape of the Ship of Theseus: replace every part one at a time, and there’s no single moment “you” stopped and a new person started.
Picture a person as a thousand links (memories, habits, plans), a tenth replaced yearly: after forty years about fifteen originals remain, yet each year stays almost fully linked to the last.
Looking inward for a single “self” behind your thoughts finds only the thoughts - a bundle, not an owner - and that bundle can still be held responsible for what it does.
