I’m not going to speak for the atheists who believe in no such thing as objective morality, as I believe in objective morality. However, if there is no objective morality, that does not mean there is not ‘relative morality’ which follows rules. The problem here is what ‘illusory’ means.
I know, it’s awful getting into definitions. However, I had this discussion with Prayson Daniel and he described “illusory” as “not real”. However, he also said that experience isn’t real (conversation linked). I think experience is real; it emerges from the material world:
“You, your joys and your sorrows, your memories and ambitions, your sense of personal identity and free will, are in fact no more than the behaviour of a vast assembly of nerve cells and their associated molecules. Who you are is nothing but a pack of neurons.”
– Francis Crick, 1994.In The Astonishing Hypothesis – The Scientific Search for the Soul, London, Simon and Schuster.
Without the nerve cells and associated molecules, there is no experience. So, in what sense is experience illusory, or not real?
If by illusory you mean false, and yet people have reliable methods by which to keep the ideas and actions of morality, what does illusory mean in this context?
