Alice on identity

For all our efforts to describe the myth of identity, we should not forget that Lewis Carroll explained it in a mere six sentences...

"I wonder if I've been changed in the night? Let me think. Was I the same when I got up this morning? I almost think I can remember feeling a little different. But if I'm not the same, the next question is 'Who in the world am I?' Ah, that's the great puzzle!"
