Plato’s Euthyphro Dilemma
“Are morally good acts willed by God because they are morally good, or are they morally good because they are willed by God?”
~ Socrates
(1) If divine command theory is true then either (i) morally good acts are willed by God because they are morally good, or (ii) morally good acts are morally good because they are willed by God.
(2) If (i) morally good acts are willed by God because they are morally good, then they are morally good independent of God’s will.
(3) It is not the case that morally good acts are morally good independent of God’s will.
Therefore:
(4) It is not the case that (i) morally good acts are willed by God because they are morally good.
(5) If (ii) morally good acts are morally good because they are willed by God, then there is no reason either to care about God’s moral goodness or to worship him.
(6) There are reasons both to care about God’s moral goodness and to worship him.
Therefore:
(7) It is not the case that (ii) morally good acts are morally good because they are willed by God.
Therefore:
(8) Divine command theory is false.
