Evolution of morality

[lilphil1989]

Rather than "moral code" I should have said "code of conduct", to avoid confusion. The code of conduct would be based on the fundamental principle. But the question for me is; is it possible to identify a fundamental principle of morality? I'm not yet convinced that it is not.

You're playing semantic games now .

The concept of a fundamental principle of morality is logically unsound because it is both fundamental (because you have called it so) and not fundamental (because it is based on your personal morality, or some kind of "average human morality") simultaneously.

Using my earlier example: "All human beings have the right to peacefully co-exist," as a starting point. Can anyone refute that that is a (or possibly "the") fundamental principle of morality?

Suppose I were to add a corollary:
"All humans beings have the right to peacefully co-exist, except those with green eyes, who are inferior, and should be subjugated at every oppurtunity"

How could you refute that without reference to your own ideas of morality?

You can't, and that's the whole point.
