You really aren't interested in learning anything, are you? You are only interested in arguing. And, it appears, half the time you are not even conversant in what you are trying to argue about!
Your thought processes are one of two things:
1. They are the products of random molecular action and therefore mean nothing.
2. They are the product of intent from a source other than the brain which uses the brain to put the thoughts into a form which can hopefully be understood by others.
You yourself have implied that there is no purpose behind the workings of the brain; that identical stimuli will produce identical results. Therefore there is no logical reason to pay attention to anything you say if you are right. For words therefore mean nothing. Your thoughts mean nothing.
Are you really sure you want to take that position?
