Divine Command Theory and Euthyphro Dilemma – Study Notes
Overview
The lecture compares two major ways religion and morality are connected: divine command theory (DCT) and secular (non-theistic) approaches. It also foreshadows natural law theory as a related topic to be discussed later. Although both DCT and natural law originate in a religious tradition, the natural law theorist is presented as disagreeing with the divine command theorist on core points.
The speaker highlights the common intuition that morality and religion are linked, and notes that most people believe in some divine being. People often rely on religious traditions/texts to answer moral problems (e.g., dietary rules, sexual morality).
The Dostoyevsky quote is used to illustrate a central tension: if God is dead, everything would be permitted. The discussion then contrasts two brothers from Dostoyevsky’s works: one atheist, one Orthodox Christian monk. The monk argues for a religious foundation for morality; the atheist would likewise push morality to be determined by human agents rather than a divine source.
The Orthodox monk (theist) claims there is no legitimate foundation for morality apart from religion; the secularist would say morality can be grounded without God.
The lecture then lays out two broad approaches to morality: theistic (grounded in God) and secular (grounded in human institutions or culture). Each has pros and cons:
Theistic approach: provides a concrete, objective foundation for right and wrong; easier for believers to know what is right. But it makes meaningful dialogue with nonbelievers difficult when foundations differ.
Secular approach: facilitates conversation with nonbelievers and avoids claims about God’s intentions; but it can be unsatisfying since it may lack a clear, ultimate, unchanging source of moral truth.
The discussion emphasizes moral obligations as the centerpiece of these theories, and notes that in Western traditions (especially Judeo-Christian and Islamic contexts) moral obligations are often grounded in divine commands.
The illustration mentions how other traditions (e.g., Buddhism) may emphasize virtue or character rather than duty to religious commands.
The central idea of moral obligation (the heart of the debate)
Moral obligations are seen as overriding our common-sense morality; they bind us regardless of our feelings in a given situation.
For the theistic view, moral obligations are typically grounded in divine commands found in religious texts or revealed to humans.
The authority behind these obligations, for religious ethicists, rests with God’s commands (and, by implication, with God’s authority to command or forbid).
Theist ethics are described as biased toward the centrality of legal-like obligations as the basis for right and wrong; other ethical systems (e.g., virtue ethics) may not center on obligations in the same way.
The lecturer stresses this Western-centric bias and contrasts it with non-Western approaches (e.g., certain Buddhist ethics) where moral clarity may come from sources other than divine commands.
Divine Command Theory (DCT): core idea and stakes
Core claim: Rightness and wrongness come from the commands of God. The authority for moral obligations comes from God’s will.
DCT formula (formalized):
Key consequence: God’s commands are overriding, even when they conflict with our ordinary or intuitive moral judgments.
A representative theologian’s statement (paraphrased):
“Right because God commands it; the command is good in itself due to God’s nature and will; there is a real distinction between right and wrong that is independent of human opinion.”
The role of God’s nature and will: The divine command theory typically ties morality to the nature and will of God; the commands are grounded in God’s nature. This is meant to defend the notion that moral truths are objective and ontologically grounded in God.
An emphasis on how DCT appears to provide a straightforward, easy-to-understand source of moral obligation (an inferentially attractive explanation: the best explanation for moral obligation is that it comes from God).
Reading the Euthyphro dilemma (the key challenge to DCT)
What the dialogue asks: What makes God’s commands morally correct? Do God’s commands ground morality because they are good, or are things good because God commands them?
Two horns of the dilemma (two possible sources of morality):
1) God has discovered the moral truth; morality exists independently of God, and God merely recognizes it and enforces it.
2) God creates the moral truth; what God commands is good simply because God commands it (morality depends on God’s will).Philosophical implications of the two horns:
Horn 1 (God discovers moral truth): If morality is independent of God, then God is not the source of moral obligations. This undercuts the idea that God alone grounds morality and raises questions about the nature and source of moral truth (and whether God is all-knowing if moral truths precede Him).
Horn 2 (God creates moral truth): If morality is identical to God’s commands, then moral facts are arbitrary—God could command murder or kindness, and such commands would make those actions morally right or wrong. This leaves serious questions about why we should trust God’s commands, given potential arbitrariness.
The dilemma is presented as a strong challenge to DCT because it forces a choice between an independent moral truth (problematic for a strict theist) or an arbitrary divine will (problematic for theistic moral intelligibility).
The dialogue cues: Socrates asks Euthyphro to define “justice” in general rather than as a single example, to avoid a merely circumstantial definition of morality.
The two main questions summarized for Euthyphro’s dilemma are:
(A) Are God’s commands morally correct because they are good in themselves (Good(a) exists independently of God and God commands a because it is good)?
(B) Are things good because God commands them (Good(a) ⇔ Command(God, a))?
The dilemma leads to two consequences for theists:
If horn (A) is true, God’s commands reflect an external morality God recognizes; morality is independent of God, which undermines DCT.
If horn (B) is true, morality is arbitrary, anchored only in God’s will, which undermines the idea of an objective, necessarily good standard and raises concerns about divine arbitrariness.
The Aristotelian/Platonic backdrop: The discussion connects to Socrates’ method in Euthyphro, where the goal is to obtain precise definitions of justice and to scrutinize the source of moral authority.
Exhaustive and exclusive: what makes a genuine dilemma?
The concept of a genuine dilemma requires two features:
Exhaustive: The two options exhaust all possibilities (no third option left unconsidered).
Exclusive: The two options are mutually exclusive (they cannot both be true at the same time).
In this context, the two horns are treated as exhaustive and exclusive options for the source of morality under DCT:
Horn 1: God discovers moral truths that exist independently of God.
Horn 2: God creates moral truths; morality is identical to God’s commands.
The idea is to evaluate which horn is more plausible and what each implies for the grounding of moral obligations.
Consequences and implications of the dilemma for DCT
If you accept Horn 1 (morality exists independently and God discovers it):
This challenges the classic theist view that God creates and grounds morality; morality would be external to God, raising questions about God’s role as the ultimate source.
It undermines the claim that moral obligations derive solely from God’s commands.
If you accept Horn 2 (morality is created by God):
Morality becomes arbitrary and could, in principle, be changed by God from one day to the next.
This raises concerns about moral stability, rational discourse about morality, and whether moral judgments have any rational justification beyond obedience to a divine will.
In either horn, DCT faces a serious challenge: either morality is independent of God or it is entirely dependent on God’s will; both options seem to conflict with some intuitive or theological commitments that many theists hold (e.g., God as omnibenevolent and omniscient).
The problem is exacerbated by interpretive plurality within theistic communities: hundreds of denominations interpret God’s intentions and sacred texts differently, which compounds concerns about whether moral truth can be grounded in a single divine source.
The two broad responses to Euthyphro and their problems
Response A (bite the bullet with Horn 2): Accept that morality could be different and grounded in God’s commands. This preserves divine command as the source of morality, but it leads to concerns about arbitrariness and the possibility that God could command morally abhorrent actions.
Objection: If morality is contingent on God’s mutable commands, why should humans accept those commands as binding or consider them truly right or wrong independent of God’s directives?
Response B (reject the basis of human reasoning about God’s reasons): Embrace epistemic humility and maintain that humans cannot fully understand God’s reasons; “ours is not to reason why” (often attributed to St. Anselm and others).
Objection: This response escapes the arbitrariness concern but undermines the rational intelligibility of morality: if we cannot understand why God commands something, it seems difficult to justify obligatory obedience or to argue coherently about moral disputes.
The lecture notes that neither response fully resolves the dilemma. Theist positions may still face interpretive challenges and potential arbitrariness, while secular accounts avoid divine arbitrariness but struggle to provide a satisfying, objective, unchanging foundation for morality.
Examples and illustrations used in the discussion
Everyday religiously informed practices:
Dietary rules across Hinduism, Islam, Judaism; some Catholics adhere to dietary rules as well.
Dietary abstention on certain days (e.g., Catholic Fridays) and possible exceptions (e.g., eating fish on Fridays as a workaround in some Catholic practice).
Religious sexual morality rules and boundaries (e.g., modesty, marriage norms) as governed by tradition.
The/Orthodox Christian monk vs atheist brothers in Dostoyevsky’s works:
The Orthodox monk derives moral obligation from Christianity; without religion, morality would lack a legitimate foundation according to him.
The atheist would argue in favor of non-religious foundations for morality and could endorse a secular or humanistic basis.
The state trooper analogy:
A trooper enforces laws; the trooper knows the laws come from the legislature, not from the trooper himself.
This analogy is used to illustrate the problem with horn (1): if God is the enforcer of a law that God did not create, or if God simply discovers a pre-existing moral law, then God is akin to an enforcer of something that did not originate with Him.
The plurality of denominations and ongoing interpretive disagreements:
The existence of hundreds of denominations reflects ongoing disagreements about God’s intentions and the proper interpretation of sacred texts.
This makes a single, universal moral foundation grounded in divine commands more problematic in practice.
The role of divine command theory in contemporary ethics
DCT seeks an objective, final authority for moral right and wrong, rooted in God’s commands.
Its attractiveness lies in offering a clear, concrete standard of morality that is not dependent on human preferences.
Criticisms include:
Arbitrariness problem: if God could have commanded differently, morality becomes contingent on God’s whims.
Euthyphro dilemma challenges the claim that God is the ultimate source of moral truth.
Pluralistic interpretive landscape among religious adherents makes a single source of morality difficult to defend.
Potential mismatch with human intuitions about morality in cases where divine directives seem to conflict with deeply held moral commitments.
Summary of key terms and concepts
Divine Command Theory (DCT):
Core claim: Rightness/wrongness is determined by God’s commands.
Formal expression:
Euthyphro dilemma: central challenge to DCT posed by Socrates to Euthyphro about the source of morality:
Horn 1: God discovers the moral truth; morality exists independently of God.
Horn 2: God creates the moral truth; morality is equivalent to God’s commands.
The dilemma raises concerns about God’s omniscience/omnipotence and the potential arbitrariness of divine commands.
Exhaustive and exclusive dilemma criteria:
Exhaustive: the two options cover all possibilities.
Exclusive: the two options are mutually exclusive.
Formally, if the dilemma D has candidates {A, B}, then for all x, x ∈ Candidates(D) implies x ∈ {A, B}, and A ∧ B are mutually exclusive.
Moral obligation: an overarching claim that binds agents to certain duties or prohibitions, potentially overriding personal or culturally relative judgments.
Classical theistic attributes referenced in the discussion:
Omnipotence (all-powerful)
Omniscience (all-knowing)
Omnibenevolence (all-good)
Objections to DCT within this lecture:
Arbitrariness problem (Horn 2): Divine commands could be arbitrary if morality is identical to God’s commands.
The interpretive plurality problem: hundreds of denominations imply divergent interpretations of God’s will, challenging the idea of a single, universal divine command.
The “Ours is not to reason why” approach (epistemic humility) avoids some concerns but reintroduces questions about rational justification for moral judgments.
Final takeaways for exam preparation
Divine Command Theory provides a simple, concrete method to ground morality in the divine, but it faces serious philosophical challenges via Euthyphro’s dilemma.
Euthyphro’s dilemma forces a choice between: (i) morality independent from God (God discovers it) or (ii) morality identical to God’s commands (God creates it). Both options create significant theoretical difficulties for a robust theistic ethics.
Secular approaches offer alternatives that avoid divine arbitrariness but may struggle to provide a satisfying, objective, unchanging foundation for morality; they also enable dialogue across belief systems but may lack a transcendent grounding.
The conversation around DCT invites you to:
Be precise about what you mean by “morality” and “obligation.”
Understand how the source of moral authority impacts debates about moral truth, moral disagreement, and moral action.
Be able to articulate the Euthyphro dilemma, its horns, and why many find both horns problematic for classical divine command theory.
Be ready to discuss possible responses to the dilemma and their strengths/weaknesses, including both the appeal to divine reasons and the stance that we cannot access God’s mind but must nevertheless follow divine commands if one believes in them.
