To what nichole said: while all cultures differ on the details of their moral system, the general feelings themselves are strikingly similar. All cultures have some concept of a "higher being", though they differ on how they view "it/Him/whatever". Also, cultures may vary on how many wives a man can have but all agree that everyone shouldn't just procreate with everyone else whenever they want to. I can't remember if I read that here or somewhere else so I may just be referencing something someone already posted.
