Reason enables us to see the self-evident truth that if I'm bigger or smarter than the other guy I will be able to rob him blind and sell him into slavery.

But that same reason should be able to tell you that a biggersmarterstronger person would be able to do the same to you. In some sense I think that rights are an act of self-preservation. Not to mention they happen to make for a much happier society.

But that same reason should be able to tell you that a biggersmarterstronger person would be able to do the same to you.

In which case reason would tell you to be the best slave that you possibly can.

Pride would tell you to fight. That's an emotion.
