Why should people try to make logical arguments….?
That is irrelevant. Whatever you decide about reality and morality you can decide but you are nonetheless still repsonsible. When someone cries ‘Help, I’m drowning” maybe he’s kidding, maybe it’s a mirage…but you are responsible if it turns out you are the cause of his death. It is totally irrelevant. You are trying to turn a moral issue into an epistemological issue. That sort of thing used to make Socrates and Plato really pissed 🙂 A system of morality which is based on relative emotional values is a mere illusion, a thoroughly vulgar conception which has nothing sound in it and nothing true.
