It's cute how you explain who Socrates is for the benefit of those who haven't heard of him.
Anyway...
How do you account for the morality of war, in which the killing of an enemy (as opposed to a compatriot) is considered "just"? If both sides consider their cause to be "just" who is truly right?
If the idea that society determines what is moral is "pathetic", why do we see such behavior?
