Just ask the late serial killer and cannibal, Jeffrey Dahmer, about this:
· “If a person doesn’t think there is a God to be accountable to, then what’s the point in trying to modify your behavior to keep it in acceptable ranges?” (Richard Weikart, "The Death of Humanity: And the Case for Life")
Well, I guess a professor of ethics could reason pragmatically:
· "Well Jeffrey, you would live a more fulfilling life if you would only give up killing and cannibalizing your victims."
But I could imagine Dahmer responding, "Trust me! I know what I find fulfilling better than you do!"
Instead, I think that Dahmer had a more rational view of morality than the vast number of our university professors. He clearly understood that if morality is just something we invent, then everything is permissible.
