So what is this self thing that makes you you? Is it bodily identity? Psychological continuity? Some immaterial soul? A bunch of neurons that are not themselves conscious and which are bundled together in ever-changing patterns without centralized control? There are no answers in the following short clip, just questions that may be interesting to think about and whose conclusions may imply we ought to change certain attitudes toward self and others.
Of course, if Hume was right, there is no self... it's just an illusion... and maybe our moral attitudes may have to radically change to correspond to that fact.
