What is unfaithfulness and how does it relate to the Newtown tragedy?

26. We evolved as a group-oriented species.

We aren't solitary hunters. We form family and tribal groups naturally. Thanks to millions of years of evolution as a social species, we have some pretty good ideas about which actions benefit the group, and which do not. Are these ideas "rooted in the meaning of existence?" Absolutely not. In order for you to prove this, you'd have to find a feral child - a human with no concept of what it means to be in a group of other humans, and quiz them on morality. Good luck with that - you've got quite a challenge ahead of you!

Those of us who don't believe a god dictated morals to humans understand that we probably have some genes that steer us toward altruistic and cooperative behavior, but that the bulk of what we call morality comes from growing up in a society of fellow humans. We learn about group dynamics. We experience what it's like to hurt others, and to be hurt by others. We come to realize that society will work best for us when we work within its framework, and follow its rules.

There have been lawbreakers from the beginning of time - there are always going to be some who believe they can get away with a certain act, or that the cost of complying with the rules is too steep. I invite you to open your own bible and read the story of Cain and Abel. There's a guy who had to know damn well that your god would know what he did, and punish him severely, but he did it anyway. So much for your belief that the "ethical imperative" is "rooted in the meaning of existence."
