William of Ockham responded to the Euthyphro Dilemma by 'biting the bullet'. He argued that, if God did command people to be cruel, then that would be morally obligatory, proposing that the only limitation to what God can make obligatory is the principle of non-contradiction. Robert Adams defended Ockham's view, noting that it is only a logical possibility that God would command what we consider to be immoral, not an actuality. Even if God could logically command these actions, he would not because that is not his character. Eleonore Stump and Norman Kretzmann have responded to the Euthyphro dilemma by appealing to the doctrine of divine simplicity, a concept associated with Aquinas and Aristotle which suggests that the substance and attributes of God are identical. They propose that God and goodness are identical and that this is what makes his commands good.
