Derek Parfit on personal identity, and why he said identity is not what matters

Derek Parfit on personal identity, and why he said identity is not what matters

Parfit's teleporter and fission thought experiments dismantle our intuitions about what makes you the same person over time — with direct bearing on mind-uploading and the continuity of the self.

Listen in the Fylom app.

Show notes

The teletransporter thought experiment suggests selfhood is a collection of data rather than an indivisible entity.

Fission cases show that two people can maintain psychological continuity with one original person simultaneously.

Relation R defines persistence as a rope of overlapping fibers like memories and current intentions.

Reductionism views a person as a series of events rather than a separate, fixed entity.

Identity is a matter of degree rather than a binary, all-or-nothing mathematical fact.

Viewing the self as overlapping mental states can diminish the fear of death and egoism.
