Thank you.

Very good points. I would suggest that understanding the workings of nature doesn't change the way we live, feel or otherwise get on with our lives.

It seems to me that we don't really see the whole picture. My friend and I are experiencing the same thing, and my friend decides to react differently to how I would react. That doesn't mean my friend is exercising free will. It merely means that he has a different history influencing his decisions. Even our different position during that experience gives us different perspectives, which flow directly into our decisions.

Right and wrong are learned. They may have evolved through our ancestors' experience, and passed down to us, over generations.

Anyway, I just like the subject. ;)
