Is a song great because it sits at number one, or is it number one because it is already great? That everyday argument is a doorway into one of the oldest puzzles in philosophy. In Plato’s dialogue, Socrates asks Euthyphro whether something is pious because the gods love it, or whether the gods love it because it is pious, and the question has haunted monotheistic theology ever since. This episode lays out both horns of the dilemma and the surprisingly high stakes attached to each.

We examine the first horn, the independent rulebook favored by Thomas Aquinas and natural law, and the sovereignty problem that led Hugo Grotius to say morality would hold even without God. Then we turn to the second horn, divine command theory, where William of Ockham and Rene Descartes push God’s power so far that even mathematics becomes arbitrary, leading to the anything goes objection and Leibniz’s charge that such a God is hard to distinguish from the devil. From there we explore the escape hatches, including restricted divine command theory, the false dilemma defense that God’s nature is the standard, the Hebrew prophets’ action-based view of righteousness, and Wes Morriston’s critique that the dilemma simply resurrects itself.

• Why making God bound by an eternal moral law demotes the creator to a mere messenger
• How Descartes defended omnipotence by claiming God could have made two plus two equal five
• The tautology problem: why saying God is good becomes meaningless under pure command theory
• Alexander Rosenberg’s secular version: did evolution discover morality or merely select for it, including traits like xenophobia
• Property rights, Thomas Hobbes, William James’s strenuous mood, and why coding goodness into artificial general intelligence faces the same ancient trap
