I have never read any books about atheism, and my daughter took me to listen to Sam Harris once.

I was both bored and unimpressed, and I do not believe that ethics steam from love.

Ethics evolved as a survival mechanism - the greater good. It is the outcome of thinking and experience. There is a direct correlation between highly intelligent people and ehtics.

The more one is capable of extrapolating outcomes, the less likely one is of unethical behaviour.

Ethical behaviour is related to survival.
