Isn't it a little disrespectful to refer to the US President as a child?

Funny you should mention that. I was just thinking about how I don't believe in the existence of "evil." IMO "good" and "evil" are nothing more than concepts created by establishments throughout history to be used as "guidelines" (euphemism alert) on how to perceive certain things in the world.

That is the conclusion one must logically come to when being a materialist.

When 900 years old, you reach. A child, everyone is!

Hehe. I'm not a materialist (I'm more of a philosophical agnostic). It just seems like the most logical conclusion given what I (think I) know about history and human behavior. Materialism and other perspectives that I'd consider to be in the same "layer" of thought don't even enter into it.

For example, let's say that the LotR "Middle Earth" setting was real. I believe that children would still be taught that certain things are "good" and certain things are "evil" regardless of whether or not they had any real association with the actual forces of "good" or "evil" that are accepted as existing in that world. I think that these concepts are most often used as a social system of control regardless of whether or not "good" and "evil" are actual "things."

I'm not saying that I know that these don't forces exist in some "real" way...just that I've personally never seen anything to convince me that they're more than concepts created by humans. I will admit that I tend to subscribe to the thinking that the simplest explanation is likely to be the most realistic one (provided little to no hard evidence to the contrary), however.

Well, I think some things considered evil or wrong stem from instinctual behaviour, for example incist is considered 'evil' which stems from the real genetic problems it can cause.

But I think most behaviours do stem from a social system, but without one I don't think society would have developed. For example arson is something that is going to make it a lot harder for a tribe to function, so tribes where that as considered wrong would have "died out" or seen that tribes where it was shunned had houses all the time and thought that was a better idea.
