The moral argument reasons from the reality of objective moral facts to God as their necessary ground. It has proved resilient precisely because it leans on a premise few want to deny (that some things are genuinely right or wrong, independent of what anyone believes or desires) and asks what could underwrite it. It must be engaged where it actually pushes, not as a restatement of the ontological argument [§5.1.7](<5.1.7 Modal Ontological Argument.md>) takes up: its force is axiological, not conceptual, and turns on the authority of obligation rather than the content of a concept.

The argument's contemporary forms tie moral obligation specifically to a personal will. Adams(Robert Merrihew Adams, 1999) identifies moral goodness with resemblance to God and obligation with God's commands; Evans(C. Stephen Evans, 2013) argues that obligations bear marks (authority, universal scope, inescapable bindingness) that only the commands of a personal, loving God adequately explain. Hare(John E. Hare, 1996) presses the "moral gap" between the demand morality makes on us and our capacity to meet it, a gap divine assistance is needed to close. Craig(Craig, William Lane, 2008) presses the argument in its most widely debated deductive form (if God does not exist, objective moral values and duties do not exist; objective moral values and duties do exist; therefore God exists), the popular syllogism that fixes the argument's public profile, with all the philosophical weight resting on its first premise: that authority of the relevant kind requires a personal commander. Baggett and Walls(David Baggett and Jerry L. Walls, 2011); (David Baggett and Jerry L. Walls, 2016) give the argument its strongest contemporary form, recasting it as an abduction rather than a deduction: theism is offered as the best explanation of the full moral landscape at once, its values, its obligations, its knowability, and the possibility of moral transformation, so that no single premise carries the inference and the cumulative fit is what is offered as evidence. Behind these stands Mavrodes's(George I. Mavrodes, 1986) point that objective moral facts sit awkwardly, are "queer", in a world with no more than nature in it; and even Mackie(J. L. Mackie, 1982), no theist, allows that objective values, were there any, would fit more easily in a theistic universe than a naturalistic one. The shared structure is an inference to the best ground: moral facts are real and categorically binding; only a personal will supplies authority of that kind; therefore God.

Grant the realism in full. Moral facts are not projections, conventions, or sentiment got up as fact; that gratuitous cruelty is wrong is true, and true independently of any attitude taken toward it. Grant, too, that bindingness is the crux: an obligation that bound no one would not be an obligation, and a naturalism that reduces value to preference or fitness-tracking does struggle to recover the authority that genuine obligation carries. The argument's animating worry is legitimate, and the present account shares it rather than dissolving it.

*First.* The ground the argument seeks is real but mislocated. What the argument adds to that worry is a personal will to supply the authority, and the dependence of morality on such a will is exactly what the book contests. The ground of moral bindingness is located at [§8.12](<8.12 Morality.md>) in the structural constitution of persons and their standing toward one another, not in commands issued from outside that order; obligation is read off what persons are and how they stand to one another, not conferred by a will above them. If that identification holds, the argument's central premise (that objective morality depends for its existence on God) is false, with the ground already supplied structurally and no further person required to issue it.

This front must be drawn at the register Chapter 8 actually licenses. The argument of [§8.12](<8.12 Morality.md>) proceeds by structural *identification*, not strict derivation: it exhibits where moral bindingness is seated, but does not derive the full content of obligation the way Chapter 2 derives modal status. A determined moral realist can decline the identification (holding that authority of the relevant kind still requires a commanding will, however well morality maps onto the structure of persons) and so keep the dependence premise alive. Taken alone, this front shifts the burden; it does not discharge it.

*Second.* The commanding will the argument names cannot be had for free. The argument's deeper trouble does not wait on Chapter 8. Grant, for the sake of the argument, that moral authority does require a personal ground: the ground the argument names still cannot supply it. The classical commanding will is typically described as atemporal, non-spatial, and immaterial. The revised [§5.1.7](<5.1.7 Modal Ontological Argument.md>) result does not make such a being semantically empty by definition. The pressure is whether a timeless divine nature or will can ground directed obligations to distinct persons while preserving determinate authority and content. Ordinary commands are temporal acts. Divine-command theorists may instead ground obligation in God's eternal nature or standing will. That move avoids a temporal issuing event but still owes an account of the directed relation between commander, content, and obligated persons. Each is a condition of succession, relation, or persistence, and a ground precluded from time, space, and substance has not been shown able to supply any of them. Adams's resembling goodness, Evans's loving commander, Hare's assisting God each presuppose a personal agent doing personal things: willing, relating, sustaining. Pressed to name the will that obligates, the moral argument points at a ground whose standing to command is exactly what remains unexplained.

A defender might relax the ground to a personal agent that does instantiate the conditions: temporal, related, present to those it binds. Then the proposal departs from strict classical timelessness. It may still claim ultimacy, but it must explain how an agent participating in temporal and relational moral life grounds rather than merely exemplifies moral authority. The revision keeps a commander by giving up the commander's ultimacy.

The argument tracks something real. Moral facts are binding, and their bindingness is not self-standing: it is grounded. The mistake is the location: what grounds obligation is not a will behind the world but the structural constitution of persons within it ([§8.12](<8.12 Morality.md>)), the same inversion the book runs throughout, fixing on a genuine feature and mislocating its bearer. The doctrines this argument carries with it (divine-command theory as an account of where obligation is grounded, and Hare's moral gap) are taken up in their own right in the Excursus, where the structural account is in hand to reconstruct what survives once the existence argument falls.

The abductive form needs separate handling, since it rests not on the single commanding act the second front dismantles but on a comparative claim: that theism explains the moral landscape better than any rival. The comparison fails at both ends. On the theist's side, an explanation is only as good as the standing of its explanans, and the classical explanans enters the comparison owing the relation problem above: a ground precluded from time, space, and substance must account for the explanatory, sustaining, and commanding relations the abduction credits to it before its explanatory fit can be scored.

On the rival side, the inference is run against a strawman naturalism that reduces value to preference or fitness-tracking. The genuine rival is robust non-naturalist realism, worked out most fully by Wielenberg(Erik J. Wielenberg, 2014): objective moral facts as brute necessary truths standing in non-causal *making* relations to their base properties, requiring no commander and no reduction to preference. That account is the near-twin of the structural identification at [§8.12](<8.12 Morality.md>), obligation seated in what persons are and how they stand to one another, and it blunts Mavrodes's queerness charge: necessary moral facts are a serious rival to divine-command accounts, but their normativity is not explained merely by analogy with necessary structural conditions. The non-naturalist still owes an account of authoritative reasons and their relation to natural persons.

Against that rival the abductive inference does not clear its comparative step, for the same reason the modal-grounding argument does not clear its own ([§5.1.8](<5.1.8 Modal-Grounding Argument.md>)): a personal ground is named as the best explanation only because the field of rivals was drawn to exclude the structural one.

*What is established.* The moral argument is right that objective morality is real and binding, and right that its bindingness must be grounded. It is wrong about the ground. Where Chapter 8's identification holds, obligation is seated in the structural constitution of persons rather than in a will above them ([§8.12](<8.12 Morality.md>)); and independently of that identification, the classical ground faces a substantive relation problem: its timeless nature or will must ground determinate obligations to distinct persons without relying on an unexplained command relation. What the argument sees (that morality is grounded) the structure supplies. What it added (that the ground is a divine will) names a being whose capacity to will and command is the very thing still owing an account.
