I think it was Aristotle who suggested, if not said exactly, this quote:

"God is a thought thinking itself."

Whatever else it may mean, it sounds nice. Thought it sounded relevant.

Well what happens if we get all our biological parts, minus the brain, replaced with synthetic or bionic replacements. Or even have some way of replacing our brain, thus eleminating all biological components?

The conclusion I have reached is that if you are going to apply the word entity (in the strictest sense) to something than that something must be a pure thing which never changes even a little bit. If it did change than it would be something else and have another name. So mathematical entities are good objects to label but a physical object is not. We may use the word loosly in everyday language but if the word is to be scrutinised than there is no hope if used on physical objects. Paradox will natually emerge.
