The dilemma is ancient. It appears in Plato’s dialogue Euthyphro, formulated as a question about piety, and its force has not diminished in two and a half millennia. Applied to theism: is something morally good because God commands it? Or does God command it because it is morally good? Both options appear to damage theism, and the argument is taken seriously in contemporary philosophy of religion.
If the first horn: morality is arbitrary. God could command cruelty, and cruelty would thereby become good. The command-theory of morality gives God no moral character, just infinite power to define. If the second horn: goodness is a standard independent of God, to which God conforms. God is then constrained by something above Himself, and we could in principle know what is good without reference to God at all.
The third option: divine nature theory
Classical theism, articulated by Anselm and Aquinas in the Christian tradition and by scholars of the Ashʿarite and Māturīdī schools in the Islamic tradition, responds by rejecting the dichotomy. The dilemma assumes that God’s commands and the standard of goodness are two distinct things. On the divine nature theory, they are not. God’s nature is the ultimate standard of goodness. He does not conform to a standard above Himself, nor does His command create goodness arbitrarily. His commands express His nature, and His nature is the eternal reality of what goodness means.
On this view, the question “is cruelty good because God commands it?” is incoherent. The incoherence is not a limitation on God’s power, but a feature of what God is. A perfectly good nature cannot command cruelty. Asking whether God could command cruelty is like asking whether a perfectly rational being could believe a contradiction. The nature rules out the possibility before it arises.
The Islamic articulation
Within Islamic theology, the relevant historical debate runs between the Ashʿarites and the Muʿtazilites. The Muʿtazilites held that good and evil are rationally knowable independent of divine command, which places them closer to the second horn of the dilemma. The Ashʿarites held that divine command is constitutive of moral obligation, which risks the first horn. The most sophisticated Ashʿarite position, developed by al-Ashʿarī himself and refined by later thinkers including al-Bāqillānī, al-Juwaynī, and al-Ghazālī, is something other than simple divine command theory. The position holds that God, being perfectly good, necessarily commands what accords with His nature. The arbitrariness worry does not arise because divine nature is not arbitrary.
The Quran establishes the position directly:
The verse illustrates the structure. God commands justice. The command does not make justice good. Justice is an expression of His nature. The command is a disclosure of the moral structure embedded in the nature of the Creator, not an arbitrary imposition.
The hadith qudsī that settles the worry
If the Ashʿarite position were genuinely at risk of the first horn, the tradition would presumably be neutral on whether God could in principle command anything at all. The tradition is not neutral. The hadith literature includes a direct statement from God in the first person:
The hadith establishes a position that the simple divine command theorist cannot hold. God describes Himself as having forbidden ẓulm (injustice, oppression) on His own nature. The wording presupposes that injustice has a stable definition that applies even to God’s own actions. God does not commit injustice because He has placed it outside Himself, by His nature. The dilemma’s first horn (cruelty would be good if God commanded it) is foreclosed by the tradition’s own most explicit statement of how the relationship between divine action and moral category actually works.
The Quranic emphasis on rational moral standards
The Muʿtazilite worry that simple divine command theory leaves moral knowledge inaccessible to reason is also addressed in the Quran. The text repeatedly invokes principles of justice, fair dealing, and care for the weak as if they were principles the reader is expected to recognise without further proof:
The verse instructs the believer to stand for justice even when the cost falls on themselves or those they love. The instruction presupposes that the believer can recognise justice independently of any particular case being adjudicated. The Quranic moral epistemology is therefore not pure command theory: God commands the believer to develop and exercise moral judgement, recognising that the human creature has the capacity, through fitrah and reason, to identify what justice requires in a given situation.
The problem for secular ethics
The Euthyphro dilemma is sometimes deployed as though it defeats theistic ethics while leaving secular ethics untouched. The question it raises (what is the ground of moral facts?) is equally pressing for any ethical system. Secular ethics must explain where moral obligations come from, why they are binding rather than merely conventional, and what makes certain things genuinely wrong rather than merely dispreferred or socially disapproved.
Moral realism without God faces its own grounding problem: if moral facts are real, mind-independent, and binding, what is their ontological status? They are not physical objects. They are not mathematical abstractions in any obvious sense. The secular philosopher who uses the Euthyphro dilemma against theism must answer a parallel question: in virtue of what are moral facts facts at all?
The divine nature theory has an advantage that purely secular accounts of moral realism lack: moral facts are real because they are grounded in the nature of the Being whose existence is itself necessary. The facts are not invented, not merely conventional, not the preferences of the most powerful. They are expressions of the character of the ground of all being, which is the reason they have the force of genuine obligation rather than mere suggestion.
Why the dilemma fails to start
The dilemma has force only as long as its two terms are held apart, as though “God” and “goodness” are two separate things whose relationship must be defined. The divine nature theory denies this starting assumption. If God’s nature just is the eternal standard of goodness, the question “which came first, the command or the moral fact?” is as confused as asking which came first, the triangle or its three-sidedness. The two are not separate things in a relationship. They are the same thing under two descriptions. Recognising this does not mean every question about divine ethics is answered. Recognising this means the particular dilemma at hand fails to get started.
The Euthyphro dilemma is a genuine problem for a theology that treats God as a powerful lawgiver operating within a pre-existing moral order, or as a being whose commands arbitrarily create goodness. Classical theism, including the dominant tradition in Islamic theology, holds neither position. The dilemma does not touch it. The Islamic tradition’s most sophisticated response runs through the divine nature theory plus the hadith qudsī establishing that God has placed injustice outside Himself by His nature. Together, the two foreclose both horns of the original dilemma without leaving theism in the position the dilemma was designed to expose.
