I know its biblical...I'm trying to get to the root of you're view of universal morality. I want to challenge you're claim that you can do whatever you want, as long as you don't hurt others. First, the most obvious, why bother following this. If for pragmatic reasons, i.e. so nobody hurts you, do you believe that the rest of the world will respect you're upholding of the universal morality and not hurt you wantonly? Clearly not, so why not do whatever you feel good about doing, as long as it increases you're own power. If there's nothing outside of your existence for you, why bother not making the most of it. Also, what about rejecting someones romantic advances. That clearly is hurting someone, but I'm sure you've done it. Do you believe you could live a life without wantonly hurting any other person?
