This is from Paul Myers, professor at the University of Minnesota, on the purpose of life:
First, there is no moral law: the universe is a nasty, heartless place where most things wouldn't mind killing you if you let them. No one is compelled to be nice; you or anyone could go on a murder spree, and all that is stopping you is your self-interest (it is very destructive to your personal bliss to knock down your social support system) and the self-interest of others, who would try to stop you. There is nothing 'out there' that imposes morality on you, other than local, temporary conditions, a lot of social enculturation, and probably a bit of genetic hardwiring that you've inherited from ancestors who lived under similar conditions.
If there is no God, and "reality" is limited to matter in motion, then what does "right" and "wrong" mean? I think Myers is on to something. He is being a consistent atheist.
