But what is your self that you are talking about?

You are in your belief entirely physical. There is no spiritual or soul part of you.

You have a physical place in your brain that stores memories, a physical place that processes and regulates things such as movement, hunger, thirst levels, fear, sexual excitement etc.

If the parts that controlled these parts of you were removed you would no longer have thought or personality, as they don't exist independently of the brain according to your world view.

Furthermore as all the cells in your body are constantly being replaced your physical body is comprised of totally different molecues than it was several years ago.

Think an axe when someone replaces the head, then years later replaces the handle. It's not the same axe any more it's physically different.

You are an entirely physical organism too. All the cells in your body have been changed and replaced many times. How can you possibly be the same person unless you have a spirit or soul independent of your physical form?

So confused...
