Hello,

I was inspired by another thread to propose this man's philosophical problem. Consider the following problems of identity propounded by Derek Parfit:

First Scenario: Take my brain and place it into another body, say a male brain to a female body. When I come to - I am still me, right? I am just now in a new body.

Second Scenario: Remove half of my brain (or just beat me till half or more is damaged beyond use). Am I still me? Even though I do not act or function as I once did, I am still me, right?

Third Scenario: Remove half of my brain again - and now place it into a different, brainless, body. I am still me but in a new body now, right?

Now, most importantly, the Fourth Scenario: If you remove of my brain and half of the brain of another person, then switch two of the halves brains in the bodies - what happens to me?! In case that was badly worded, take half of my brain and put it into the body of another person then take that persons half brain and put it into my original body. Who is me now? Both bodies should have recollection being me, right? So which one is me? The one who claims to be me first..?
