Personal Identity

Time Travel

(Work In Progress: output at 30/05/2024)

Plug Note¹

• Thesis Text:
  1. From the perspective of Personal Identity, Time Travel enters into various Thought Experiments².
  2. Time Travel is sometimes taken as a knock-down argument against Endurantism³, because if you travel back in time to talk to your former self, it doesn’t look as though you can be wholly present at a particular time, as different “time slices” of “you” are located in different places at the same time.
  3. Perdurantism⁴ isn’t worried by this TE, though it would seem to make the topology of the spacetime worms rather complex (and scattered).
