@sonship saidDo not cause harm. Do not deceive. Do not coerce. That's broadly speaking, of course; refer to your moral compass when you need to make decisions about the nitty-gritty of applying those three ideals to the navigation of your interactions in your everyday life. Take full responsibility [e.g. don't blame supernatural beings for your immoral acts]. And if your character means that you don't always have the courage to stick to your principles ~ and you behave inconsistently ~ just try your best. There is some guidance.
I want to here the what the atheist philosophy GUIDANCE is on the problem of moral behavior / conscience disharmony.
@sonship saidWhat are your answers to these two questions? I have answered both.
On what basis did the nations have any right to conduct the Nuremberg trials against the former Nazis?
What gave other communities the authority to pass judgment on the Nazis that their community committed crimes against humanity?
