Forgive me for jumping in and ruin your off-topic discussion, I have an issue that I need you to resolve for me.
I tend to think of myself as more than just my physical body. I am more than just a collection of molecules. I am more than a collection of firing neurons that are arranged in a specific way. Yes, it is true that I am the result of the specific arrangement of neurons. But what I am is greater than the collection of the parts.
That said, I have been bothered by the concept of multiple personality disorder. I have done some study of this phenomenon in psychology. I know that mainstream psychology dismisses the alternate personalities as just aberations around the core personality. But I really do see them as having a potential to have a soul of their own. They certainly exhibit all signs of being different people existing in the same body.
The question is this. Treatments for such "disorder" range from merging these personalities into one to downright killing all but one. Isn't this murder?
