Here's the game: you can only reply with a single short (use your judgement) sentence.
Plato posed a simple question in his dialogue
Euthyphro: What is the source of what we think is good and bad, or right and wrong? Putting aside the relative truth of religion for a moment, does good and bad come from God, or is it grounded in a different standard of truth outside God? Basically, are God's commands arbitrary, or are they grounded in something? Is an act morally good because God wills it or is it good because God agrees that it is good?
IMPORTANT: Assume (correctly) that it's possible for God to exist and for good to come from another, possibly higher source. You don't need an atheist to think that right and wrong are grounded not just within God, but within the universe itself.
So, here's the question:
Do good and bad, and right and wrong come from God (or whichever deity), or are they grounded in something else, like humanity or the very structure of the universe?
