[Challenge for today: Try to think of (and possibly ask) at least one question.]
Have you ever (to your knowledge) had a false memory?
The “chain of stages” account of diachronic identity across changes:
The basis for thinking that X is identical at different times despite changes occurring between these times is that these changes occur in increments where at each change, the majority of X’s properties remain unchanged.
For Locke, personal identity over time works the same way, but with personality traits instead of material parts.
Memory is especially important for Locke’s view.
Locke says that identity is preserved so long as one’s consciousness can be extended backwards. Most commentators interpret this as memory.
I am the same person today as yesterday because I can remember things from yesterday as having happened from a first-person point of view.
Why does Locke reject material theories of personal identity?
Body switch thought experiment
Why does Locke reject the soul theory of personal identity?
a) Souls are not perceived (empiricist theory of knowledge)
b) “Soul wipe” thought experiment
c) (Indirectness of substance)
