What we're studying
Many who reject God still believe in objective morality. This position — sometimes called godless moral realism — is philosophically serious but faces real problems: it cannot easily explain why moral facts exist, why they apply to us, or why we should care. The grounding problem is where the action is.
The case in brief
Godless moral realism has three main forms: (1) Platonic — abstract moral values exist in a realm of their own (Wielenberg, Enoch). (2) Naturalist — moral facts reduce to natural facts about well-being or flourishing (Sam Harris, Philippa Foot). (3) Constructivist — morality is constructed by rational agents under ideal conditions (Korsgaard, Rawls). Each faces difficulties: Platonism hangs moral facts in causal vacuum; naturalism faces the is/ought gap; constructivism loses its binding force on agents who reject the construction. Theistic grounding locates the good in God's necessary nature, anchoring moral facts to a personal reality rather than abstract shadows.
What if someone says...
"Theism faces the Euthyphro dilemma, which is no better."
Classical theism splits the dilemma by grounding the good in God's necessary nature: not arbitrary command (horn 1) and not independent of God (horn 2). Godless options do not have an analogous third way.
"The phenomenology could be an evolutionary illusion."
If the phenomenology is illusion, our moral judgments are untrustworthy across the board — including any moral critique of theism. Evolutionary debunking arguments prove too much.
