Megan, I said there is no inherent meaning in the universe, only the meaning we make. I was not comparing here the morality of the meaning one individual or group creates. That's for another discussion.
Why are going on about the Golden Rule? Are you saying that because a system of morality works better, or is adopted by a majority, that it is a more inherent part of the universe?
What I meant by my remark is that humans make meaning. That's all the meaning there is. As you say, "no absolute truth." We are each free to generate meaning in our lives that work for us (or don't). We're free, and that's a meaning I make!
So, what exactly are you on about with the golden rule? Speak simply please; I haven't had my coffee yet.
