To be clear are you saying that the brain in its wiring is responsible for all of my thoughts? If you feel this way I have to ask about the soul or spirit of a person. If my thoughts came from evolution and the development of the brain and no other source then we have no soul or spirit. Our thoughts are an illusion and are the work of the initial wiring and developed structure from the environment and a collection of memories. Let me know how you see this and then we can chat some more. I sure don't want to place words in your mouth like a belief in evolution would seem to dictate.
I think I really screwed this up. :-) I think your brain is responsible for your ability to think. Was that more clear?
I'll probably screw this up multiple times. Just trust me.
:-D
