Parfit and Hume on Personal Identity

The video explores the concept of personal identity through the lens of philosophers David Hume and Derek Parfit. Hume argues that the self is an illusion, a bundle of impressions without a constant core. Parfit expands on this with a thought experiment involving teleportation, suggesting that identity is not fixed but rather a series of psychological connections over time. The video discusses the implications of these theories on personal responsibility and promises, suggesting that identity is fluid and ever-changing.
