I believe in the "noble savage" without the "noble."
I do not believe in the "noble savage" myth that was popularized by Rousseau. Nor the Blank Slate of John Locke. There are genes. Some genes are suggestions. Some genes are dictators. But there is also the social meme that plays a role [Howard Bloom in the Lucifer Principle.] Thus it is clear to me that Western Civilization had at least these factors: (1) genes and (2) the Law of Moses (3) Plato and Aristotle.
