So how many neurons must be in different states to constitute having a "different" person? If *any* change is sufficient, then the person who inhabited this body half a second ago is dead. I certainly am not having the same thoughts now as I was an hour ago, yet am I not the same person? If I am still the person that had those thoughts, then it seems to follow that small changes in thought patterns do not a different person make.

It seems to me that *any* mental state that a person is capable of reaching in less than a day must be fairly similar to those she had a day ago. The bare surface of current thought may seem radically different, but that alone is not enough to make a different person, is it?

I would say that continuity of experience is also important here, though.
