The Claim and Its Contradiction
The argument arrives with the confidence of a self-evident truth. Without God, there is no morality. Remove the divine lawgiver and the moral law dissolves with him, leaving nothing but appetite and power. It is the most frequently deployed objection to secular ethics, repeated from pulpits, published in apologetics texts, and pressed upon every atheist who has the misfortune of discussing the subject at a family dinner. The trouble is not that the claim is difficult to answer. The trouble is that every believer who makes it refutes it themselves, often within the same conversation, by doing something that their own argument says should be impossible.
They open their scriptures and they edit them. Not formally, not with a committee or a press release, but quietly and continuously, generation after generation. The passages commanding the enslavement of conquered peoples are set aside as products of their time. The instructions for executing homosexuals are reinterpreted as metaphor or cultural context. The divine mandate to commit what any modern court would call ethnic cleansing is read allegorically or attributed to a phase of revelation that has now, conveniently, passed. And the passages about love, compassion, mercy, and justice, those are retained as the timeless moral core of the faith.
The question is not whether believers are right to make those selections. Many of the retained passages do express genuine moral wisdom. The question is: what is doing the selecting? What standard is being applied when a congregation in twenty-first-century Birmingham decides that Leviticus 25:44, which explicitly permits the purchase of slaves from neighbouring peoples, does not represent God’s eternal moral will, while the Sermon on the Mount does? The answer is not the text itself, which offers no such hierarchy. It is not another text, which would simply push the problem back one level. It is a moral intuition that the congregation carried into the room before they opened the book, a standard by which they are judging the scripture rather than being judged by it.
That standard is what this essay is about. Where it comes from, how it developed, why it is far more robust and far more morally serious than the claim that it requires a divine underwriter, and why the religious appropriation of that standard as its own invention is one of the more audacious intellectual thefts in the history of ideas. Christopher Hitchens stated it plainly: “Human decency is not derived from religion. It precedes it.” The argument that follows is the extended case for why that short sentence is correct in every particular.
The Euthyphro Dilemma: A Problem That Has Never Been Answered
The philosophical difficulty at the heart of divine command theory is not new. Plato identified it in the dialogue Euthyphro, written around 380 BCE, and the intervening two and a half millennia of theological effort have not resolved it. Socrates poses the question to Euthyphro with characteristic precision: is something pious because the gods love it, or do the gods love it because it is pious? The modern restatement is equally clean: is something morally good because God commands it, or does God command it because it is morally good?
Both available answers are fatal to the apologist’s position. If something is good simply because God commands it, then morality is entirely arbitrary. God could in principle command cruelty, the torture of innocents, the worship of suffering, and those things would instantly become moral requirements. The divine command would not track goodness; it would constitute it by fiat. Many believers, understandably reluctant to accept this conclusion, insist that God would never command such things because God is good. But this response conceals the problem rather than solving it. The moment you say that God would not command cruelty because cruelty is wrong, you have invoked a standard of wrongness that is independent of God’s will and by which God’s own commands are being measured. Goodness is no longer whatever God says; it is a standard that even God is expected to meet.
The second horn of the dilemma is equally uncomfortable. If God commands things because they are good, then the goodness exists prior to and independently of God’s command. God becomes, in effect, a moral reporter rather than a moral legislator: identifying and transmitting a standard that He did not create. In that case, the standard is available in principle without the intermediary, and the central claim of divine command theory collapses entirely. Morality would not require God because it would be a feature of reality that God himself is navigating by.
Sophisticated theologians are well aware of the dilemma. The most common escape route, associated particularly with Thomas Aquinas and his natural law tradition, is to argue that God’s commands simply express His nature, and that His nature is goodness itself, so the question of whether goodness is prior to or derived from God’s will is dissolved rather than answered. God does not consult an external standard because He simply is the standard. This is philosophically ingenious, but it generates its own difficulties. If goodness is identical with God’s nature, we still need some way of knowing what that nature is, and we are immediately returned to the text and its problems. When God’s nature, as reported in the Old Testament, includes the endorsement of slavery, the command to stone disobedient children, and the instruction to commit genocide against the Amalekites, the claim that this nature simply is goodness requires the believer to perform extraordinary moral contortions. What almost all of them do, sensibly enough, is quietly decline to follow those commands, which means they are judging God’s reported nature by their own prior standard of goodness rather than deriving their goodness from His nature.
The Euthyphro dilemma does not merely wound divine command theory. It identifies a structural impossibility at its core. Either morality is arbitrary, which is monstrous, or it is independent of divine will, which makes the divine legislation redundant. The apologist’s claim that morality requires God as its foundation is not defeated by irreligion; it is defeated by the logic of its own position, and has been for twenty-four centuries.
The Scriptural Record: Evidence Against the Claim
It is worth pausing on the scriptural record in some detail, not to score points by listing atrocities, but because the content of the relevant texts is directly relevant to the central question. If the Bible, the Quran, or any other revealed text is the source and standard of morality, then the morality it contains must be evaluated on its own terms. The claim being tested here is not merely that God exists but that God authored the moral law that human beings require. The content of that law, as actually recorded, tells us something important about whether the claim holds.
The Old Testament endorses chattel slavery explicitly and at length. Leviticus 25:44-46 specifies that the Israelites may purchase slaves from the surrounding nations and pass them to their children as heritable property. Exodus 21 provides detailed regulations for the treatment of slaves, including the permissible conditions under which a master may beat a slave without legal penalty. The only restriction is that the slave must survive for more than a day after the beating; if the slave recovers before dying, the master bears no legal consequence. Numbers 31 records Moses ordering his soldiers to kill all Midianite men, all women who had known men sexually, and all male children, sparing only the virgin girls for themselves. Deuteronomy 22 stipulates that a bride who cannot prove her virginity on her wedding night must be stoned to death at her father’s doorstep. Robert G. Ingersoll, writing in 1890, observed with characteristic directness: “We all know that the Bible upholds slavery in its very worst and most cruel form; and how it can be said that a religion founded upon a Bible that upholds the institution of slavery has taught and established the fact of human brotherhood, is beyond my imagination to conceive.”
The response almost universally offered by contemporary believers is that these passages reflect the moral standards of a particular ancient culture and that progressive revelation, fulfilled covenant, or the supersession of the Old Testament by the New renders them obsolete. Some of this is genuinely subtle theology, particularly within traditions that take a developmental view of revelation. But the argument carries a cost that is rarely acknowledged openly. The moment you say that some parts of the text reflect ancient cultural conditions rather than timeless divine command, you have introduced a criterion for distinguishing timeless from time-bound that comes from somewhere other than the text itself. You are using a moral and historical judgement, formed by secular reasoning, Enlightenment values, and hard-won moral progress, to adjudicate which portions of the scripture represent authentic divine instruction. The text is no longer the authority; it is the material being assessed by an authority that sits entirely outside it.
This is not a minor concession. It is the entire argument. The believer who says “of course we don’t endorse the slavery passages; those reflect ancient Near Eastern culture” has already, in that sentence, confirmed that the moral standard by which slavery is identified as wrong is prior to and independent of the scriptural text. They brought that standard to the book. The book did not give it to them. If the book had given them their moral standard in its totality, they would have no grounds on which to identify any passage as culturally conditioned rather than eternally commanded. The very capacity to distinguish between the morally acceptable and morally unacceptable portions of scripture proves that the distinguishing faculty operates on a basis other than scripture alone. The editing is the confession.
Where the Standard Actually Comes From: Evolution, Empathy, and Social Reasoning
If the moral standard does not come from divine command, the obvious question is where it does come from. The apologist often presents this as though the secular answer must be arbitrary preference or naked self-interest, as though removing God necessarily removes the basis for preferring kindness over cruelty. This is a serious misrepresentation, whether through misunderstanding or deliberate rhetoric, of what secular accounts of morality actually claim.
The evolutionary account is the most foundational. Human beings are a deeply social species. Our ancestors who survived long enough to pass on their genes were, overwhelmingly, those who lived in cooperative groups, who felt the pull of reciprocal obligation, who experienced something like distress at the suffering of their kin, and who could coordinate well enough to face threats that no individual could survive alone. The neurological and psychological apparatus that underlies moral intuition, the capacity for empathy, the aversion to fairness violations, the sensitivity to social reciprocity, did not fall from the sky. It was selected for over hundreds of thousands of years because groups with those capacities outcompeted groups without them. Frans de Waal’s decades of research into primate behaviour demonstrated convincingly that the precursors of moral behaviour, consolation, reconciliation, fairness sensitivity, proto-altruism, appear in chimpanzees and bonobos, in species whose separation from our lineage long predates any religious tradition. The moral emotions are not a recent divine installation. They are an ancient evolutionary inheritance, and they predate the oldest religious text by an incomprehensibly long margin.
None of this means that evolutionary origins simply justify moral claims, which would be the naturalistic fallacy. What the evolutionary account establishes is that the moral emotions are real, consistent, cross-cultural features of human psychology that existed long before any revealed religion and that do not require supernatural explanation. The capacity to feel that cruelty is wrong, that fairness matters, that the suffering of others demands a response, these are not arbitrary preferences. They are deeply rooted features of what it is to be a social mammal of our particular kind, and they are present in societies that have never encountered the Abrahamic tradition as surely as they are present in societies that have been saturated with it for millennia.
Above the evolutionary foundation sits what we might call the rational and social layer of moral development. Human beings are not merely creatures of instinct. We reflect on our instincts, argue about them, extend them, and sometimes override them when reason identifies a conflict. Peter Singer’s work on the expanding circle of moral concern is relevant here: the history of moral progress is substantially the history of recognising that the capacity for suffering, not membership in a particular tribe, nation, or species, is what grounds moral consideration. This is not a conclusion delivered by revelation. It is one reached by the application of the same faculty we use to understand mathematics and medicine: the capacity for consistent, evidence-sensitive reasoning applied to the question of what harm is and why it matters.
The social contract tradition, running from Hobbes through Locke, Rousseau, Kant, and Rawls, offers a complementary account in which moral rules are understood as the principles that rational agents would choose if designing a system of cooperation under fair conditions. John Rawls’s veil of ignorance thought experiment, in which you are asked to choose principles of justice without knowing what position you will occupy in the resulting society, generates robust, demanding moral conclusions with no appeal to divine authority whatsoever. The conclusions it reaches, something like equal basic liberties, fair equality of opportunity, and the priority of the worst-off, are not secretly religious conclusions. They emerge from the logic of rational agency applied to conditions of social cooperation, and they are available to anyone capable of following the argument, regardless of their theological commitments or lack of them.
Ayaan Hirsi Ali, drawing on the intellectual tradition that produced these accounts, identifies their basis clearly: “Morality in this worldview is determined by human beings, not by an outside force.” The claim is simple, and the evidence for it is overwhelming. Morality is something human beings work out, have always worked out, and are still working out, through the same combination of emotional response, practical experience, and rational reflection that produces all other human knowledge. It has not arrived in a book. It has been built, imperfectly and incrementally, by the species that needed it in order to live together.
The Taboo Morality Trap: What Religion Actually Tends to Deliver
It is worth examining not just the philosophical claim but the practical record of what religion has delivered as moral guidance when it has been in a position to impose its standards. Bertrand Russell, assessing the moral framework that institutionalised religion has typically propagated, wrote with characteristic precision: “If throughout your life you abstain from murder, theft, fornication, perjury, blasphemy, and disrespect toward your parents, your church, and your king, you are conventionally held to deserve moral admiration even if you have never done a single kind or generous or useful action. This very inadequate notion of virtue is an outcome of taboo morality, and has done untold harm.”
Russell is identifying something structurally important about the kind of morality that divine command theory tends to produce in practice. When morality is understood as a set of rules issued by an authority, the moral question becomes: have the rules been followed? This is the logic of taboo. The substance of the rules, whether they actually produce human flourishing, reduce suffering, or build more just communities, is secondary to the question of compliance. A man who has attended church every Sunday, refrained from blasphemy, honoured his parents, and never touched another woman can consider himself morally upstanding while treating his wife with habitual contempt, exploiting his workers, and voting consistently for arrangements that keep the poor in poverty. He has not violated any of the explicit commands, so the taboo-morality framework has no straightforward mechanism for condemning him. Morality conceived as rule-following, in the absence of a deeper account of why the rules matter and what they are for, tends to produce exactly this kind of compliance without virtue and observance without conscience.
Secular ethics, by contrast, begins from the question of consequences for sentient beings, or from the question of what principles rational agents could agree to, or from the question of what traits and dispositions constitute genuine human flourishing. These are harder questions than “have I followed the commands?” They require ongoing reasoning rather than simple compliance, and they produce moral conclusions that can be revised when evidence suggests the current conclusions are wrong. This revisability is typically presented by religious apologists as a weakness: if morality can change, it is merely subjective, merely preference, merely fashion. The argument that follows will address this objection directly. For now, the relevant observation is that the historical record gives us no particular reason to trust moral conclusions derived from authority-compliance rather than from sustained reasoning about the actual conditions of human wellbeing. The results of the taboo approach are visible in the record; they are not encouraging.
Moral Progress and the Consistent Opposition of Organised Religion
The relationship between organised religion and moral progress over the past several centuries is a matter of historical record rather than mere assertion, and the record is not flattering to the claim that religion has been morality’s custodian. The major moral advances of the modern era, the abolition of slavery, the extension of democratic rights to people without property, the enfranchisement of women, the decriminalisation of homosexuality, the recognition of children’s rights, the development of international humanitarian law, were achieved against the explicit institutional opposition of the dominant religious bodies of their time.
This is not a matter of disputed interpretation. The Southern Baptist Convention in the United States was founded in 1845 explicitly to defend the institution of slavery against the abolitionist position, citing scripture as its authority. The Catholic Church maintained its formal condemnation of religious liberty and liberal democracy through the Syllabus of Errors until 1965. The Anglican, Catholic, and evangelical churches in Britain were substantially opposed to women’s suffrage; the Archbishop of Canterbury, Randall Davidson, opposed the Suffrage Bill in 1912 on theological grounds. The institutional churches of England and America opposed the decriminalisation of homosexuality, and many of their current expressions continue to treat LGBT people as morally disordered or spiritually deficient. In every case, the moral advance came despite the institutional church, driven by secular reasoning, empirical argument about harm and rights, and the expanding moral circle that Enlightenment thinking had made possible.
Jerry Coyne states the dynamic plainly: “Religious morality, at least as promulgated by priests, rabbis, imams, and theologians, is usually one step behind secular morality.” The pattern is consistent enough to be diagnostic. Secular society reaches a moral conclusion through argument and evidence, religious institutions resist it for a generation or two on the authority of scripture and tradition, and then the churches slowly incorporate it into their theology, sometimes even claiming retrospectively that it was their position all along. The opposition to slavery is now presented by many Christian denominations as a Christian achievement, citing the Quakers and William Wilberforce, while the institutional mainstream that provided theological cover for the slaveholders for two centuries is quietly omitted from the narrative. The pattern of belated adoption followed by retroactive ownership is not confined to any single tradition, and it repeats with sufficient regularity to constitute a structural feature of how religious institutions relate to moral progress rather than an occasional unfortunate exception.
This pattern does not mean that religious individuals have never been on the right side of moral questions. Many have been, and often motivated by their faith’s emphasis on human dignity, compassion, and justice. The claim is not that religious belief is incompatible with moral decency; it manifestly is not, and making that claim would be both false and unfair. The claim is that when the institutional church has had the power to set the moral agenda, the record shows consistent resistance to the extension of rights and consistent defence of existing hierarchies. The moral progress, wherever it has come from, has been made by those who appealed to reason and to the principle of harm, not by those who appealed to authority and command. When the religious reformers succeeded, it was because they were making a secular argument in theological language, not because the theological framework itself generated the conclusion.
The Secular Societies Objection: What the Evidence Actually Shows
The apologist’s prediction about secular societies is stark and specific. Remove God from public life, remove the moral framework of religion from the culture, and moral collapse follows: crime rises, trust evaporates, the weak are exploited, and the social fabric disintegrates. This is a testable prediction rather than a mere philosophical claim, and we have the data against which to test it.
The Nordic countries, Denmark, Sweden, Norway, and Finland, are among the least religious societies on earth by virtually every measure: rates of belief in God, rates of church attendance, rates of prayer, and rates of self-identification as religious. They are also, by virtually every measure of social health and moral functioning, among the best-performing societies on earth. They have the lowest rates of violent crime, the highest levels of social trust, the most generous welfare states, the best outcomes for children, some of the world’s lowest levels of corruption, and consistently high scores on measures of subjective wellbeing. They are not the only examples: the Netherlands, Belgium, the Czech Republic, Japan, and New Zealand are all highly secular by comparative standards and all perform strongly on the measures that track human flourishing rather than merely religious observance.
The United States, by contrast, is the most religiously observant wealthy democracy in the Western world. Church attendance is high, belief in God is nearly universal by comparative standards, and religious identity is a major organising feature of political and cultural life. The United States also has the highest rates of violent crime, the highest rates of incarceration, the highest rates of teenage pregnancy, and some of the worst outcomes for childhood poverty among wealthy nations. None of this is straightforwardly causal in either direction: the Nordic countries’ social cohesion has multiple historical, economic, and cultural determinants, and America’s difficulties are similarly overdetermined. But the data categorically refute the specific prediction that secular societies must be in moral free-fall. The secular societies are not collapsing. Several of them are producing more equitable, more trusting, and more peaceful communities than their more religious counterparts, and the apologist who predicted otherwise owes the evidence a reckoning.
Sociologist Phil Zuckerman’s research, summarised in his 2008 book Society Without God, involved extended fieldwork in Scandinavia specifically to investigate whether highly secular societies suffered the moral and social difficulties that religious apologists predicted. His finding, stated without equivocation, was that they did not. Danish and Swedish society was characterised by high levels of civic participation, genuine concern for the vulnerable, strong norms of honesty and fairness, and robust senses of personal responsibility, none of which required religious motivation or divine sanction. Zuckerman was careful not to claim that secularity caused these outcomes, but the data made clear that the absence of God from public life had not produced the moral vacuum that divine command theory predicts it should. On the contrary, societies that had removed divine authority from the centre of their public reasoning had developed generous, functioning, morally serious communities by the application of exactly the secular principles that the apologist insists are insufficient.
For anyone who would like to examine this question further, the essay on the myth of moral collapse without religion develops the empirical case in considerably more detail, drawing on cross-national data about social trust, crime, and institutional integrity.
The Positive Case: Morality as a Human Achievement
There is something genuinely important in the apologist’s unease about secular morality, even if the conclusion drawn from it is wrong. The concern is that without a fixed, external standard, morality becomes merely a matter of preference, that there is no principled difference between the moral conclusions of a Wilberforce and those of a slaveholder if both are merely expressing culturally conditioned feelings. This is the relativism objection, and it deserves a serious answer rather than dismissal.
The answer begins with a distinction between moral revisability and moral arbitrariness. The fact that our moral understanding has changed, that we have extended the circle of moral consideration from the tribe to the nation to the species and beyond, does not mean that moral conclusions are merely arbitrary preferences. It means that moral reasoning, like scientific reasoning, is a process of progressive correction toward better understanding. We changed our view on slavery not because fashions changed but because arguments succeeded: arguments about the capacity for suffering, the inconsistency of claiming liberty for oneself while denying it to others, and the evidently false premise of natural racial hierarchy. Those arguments were good arguments in the sense that they were logically sound, empirically grounded, and consistent with the principles that even the defenders of slavery claimed to hold for their own group. Moral progress is real progress, not mere change, because it is driven by reasoning that exposes error and inconsistency rather than simply replacing one preference with another.
Consider the contrast with divine command morality on this specific point. On that model, moral knowledge does not progress through reasoning; it arrives through revelation and is then defended against revision. The consequence, as the historical record confirms, is that moral conclusions endorsed by divine authority become extraordinarily difficult to revise even when they are clearly wrong. When the institution that holds the authority has material and political interests in maintaining an existing moral conclusion, the resistance is compounded further. The abolitionist movement had to argue not just that slavery was economically unnecessary or politically inconvenient but that the scriptural endorsements of it were misunderstood, that revelation was progressive, that the spirit of the law overrode its letter. They had to do secular moral reasoning and then translate it into theological language acceptable to the authorities, which was laborious, contested, and took far longer than it should have done because the claimed divine sanction for the existing practice acted as a brake on moral revision that secular reasoning alone would never have installed.
Secular morality’s revisability is therefore a strength rather than a weakness. It means that when we are wrong, as human beings inevitably sometimes are, we have the mechanisms to recognise the error and correct it. The correction comes through argument, evidence, the testimony of those harmed, and the application of consistent principles. No one needs to wait for a new revelation. No one needs to convince a religious authority to update its doctrine. The argument can be made directly, assessed on its merits, and if it is good enough, it changes minds and eventually changes institutions. This is not the moral chaos that the apologist fears; it is moral maturity, the recognition that ethical understanding is something human beings work out together through sustained and honest reasoning rather than something handed down from above and accepted on authority because the authority demands it.
The resources for this kind of moral reasoning are not thin. They include a rich understanding of human psychology and the conditions of flourishing developed over decades of empirical research; they include centuries of philosophical argument about justice, rights, virtue, and harm; they include the expanding body of evidence from across human societies about what institutional arrangements actually tend to produce trust, cooperation, and wellbeing. These resources are available to anyone with the patience to engage with them, regardless of their metaphysical commitments. They are not the property of any denomination, and they do not require the endorsement of any priest or prophet. For a fuller treatment of how this secular moral framework operates in practice, the essay on morality without god works through the philosophical foundations in some detail.
The Concession and Its Withdrawal
It is important, in the spirit of honest engagement, to acknowledge what the religious tradition has genuinely contributed to moral thinking, because the contribution is real and should not be dismissed by anyone who wants to make an honest case rather than a flattering one.
Religious institutions have, historically, provided communities in which moral expectations were made explicit, enforced, and transmitted across generations. The idea that every human being possesses an inherent dignity that cannot be forfeited, regardless of their utility to the state or the market, has deep roots in religious thought, particularly in the Abrahamic concept of persons made in the image of God. The social infrastructure of moral community, the gathering of people around shared commitments to honesty, generosity, and mutual care, is something that religion has done reasonably well in many of its expressions and many of its historical moments. Many of the people who drove moral progress, the abolitionist Quakers, the women’s rights advocates who drew on scripture’s language of equal dignity before God, were genuinely and sincerely motivated by their faith and not merely using religious language as rhetorical cover for conclusions reached elsewhere.
All of this is true, and none of it requires the supernatural claim to be correct. The social and psychological benefits of moral community are real benefits that do not depend on the existence of the God who is nominally at their centre. The language of inherent dignity is compelling moral language that survives translation into secular terms, as the Universal Declaration of Human Rights demonstrates: its account of inalienable rights makes no appeal to divine sanction and is not weakened by that absence. The fact that religious motivation has sometimes driven people toward moral courage does not establish that the religious metaphysics underwriting that motivation is true. Many things motivate people to good action, including false beliefs, and the action is valuable regardless of the motivation. The Quaker abolitionist’s courage was admirable whether or not his theological picture of the universe was accurate, and it remains admirable on entirely secular grounds.
What the concession does not grant is the central claim: that religion is the source, the foundation, or the author of the moral standard by which we evaluate conduct. The historical record, the philosophical argument, and the sociological evidence all point in the same direction. The moral standard by which we judge religions, scriptures, institutions, and individual believers is a human standard, developed through human experience, refined through human reasoning, and revisable through human argument. Religion, at its best, has channelled and expressed that standard. At its worst, it has obstructed, distorted, and weaponised it. But it did not create it, and it cannot own it, however persistently it repeats the claim to authorship.
The Asymmetry That Believers Rarely Notice
There is an asymmetry in the debate about religious morality that is almost never examined directly, and it is worth dwelling on because it exposes something fundamental about the structure of the apologist’s claim. When a secular philosopher argues for a moral conclusion, the argument is evaluated on its merits: are the premises sound, is the reasoning valid, does the conclusion follow, does it cohere with our considered judgements about cases? When a religious authority asserts a moral conclusion on the basis of divine command, the argument, strictly speaking, is: God said so. The question of how we know God said so, and how we know we have interpreted correctly what God said, is answered by appeal to the text, the tradition, or the institution, all of which are human productions of varying historical reliability and no small amount of internal contradiction.
The asymmetry is that the secular argument is accountable in a way the divine command is not. If a secular philosopher’s moral argument is bad, it can be shown to be bad: the premises can be contested, the reasoning exposed as invalid, the conclusion shown to conflict with cases where our moral judgements are clear and widely shared. If a divine command is bad, the believer faces an awkward choice between saying God made a moral error, which is theologically impossible within most traditions, and saying that the command is being misread or misapplied, which requires exactly the kind of independent moral reasoning that the divine command theory was supposed to make unnecessary. The claimed divine origin of a moral rule does not make the rule better; it makes the rule harder to challenge, which is a deeply different thing and not obviously desirable in a species that is still, demonstrably, working out its moral understanding.
The most honest religious thinkers have acknowledged this difficulty at various points. John Stuart Mill, reflecting on his father James Mill’s rejection of religion, noted that the grounds were primarily moral rather than merely intellectual: his father found it impossible to believe that a world so full of evil was the work of an Author combining infinite power with perfect goodness and righteousness. The argument is precisely this asymmetry applied to the problem of evil: the moral standard by which the world’s suffering is identified as incompatible with a perfectly good creator is a standard that the believer must already hold in order to make the theological claim that God is good. If you derive your moral standard entirely from God, you have no basis for applying it as a test of God’s existence or nature. The fact that the problem of evil is felt as a genuine philosophical difficulty by believers and unbelievers alike is powerful evidence that the moral standard doing the feeling is not itself derived from belief in God; it is prior to that belief and independent of it.
Responding to the Strongest Objection
The most sophisticated version of the religious objection to secular morality is not the simple “without God everything is permitted” claim but rather the transcendental argument: that objective morality requires a transcendent grounding, that moral facts cannot be merely natural facts, that if morality is simply a feature of evolved social psychology it cannot be genuinely normative, it cannot tell us what we ought to do rather than merely describing what we tend to do. This is a real philosophical challenge, and it deserves a serious response rather than a dismissal.
The response has several components. The first is that the transcendental argument does not establish that God is the required foundation; it establishes that morality requires some grounding, and then assumes without argument that God is the only possible grounding. Moral realism of a non-theistic kind, the view that moral facts are objective features of reality even if they are not supernatural, has been defended carefully by philosophers including Derek Parfit, Russ Shafer-Landau, and T. M. Scanlon. These accounts differ in their details but share the conviction that moral reasoning tracks real features of the world, such as the capacity of beings to suffer and to flourish, and that those features provide genuinely normative reasons for action without requiring a divine legislator to make them binding. These positions may be contested, as all substantive philosophical positions are, but they are not refuted by the mere existence of the theological alternative. The transcendental argument needs to show that non-theistic moral realism is impossible, not merely that it is unfashionable in some circles, and that case has not been made.
The second component is that the transcendental argument, applied consistently, generates difficulties for the theist as well as the atheist. If objective moral facts require a transcendent grounding, we are returned immediately to the Euthyphro dilemma: either God’s commands constitute the moral facts, making them arbitrary, or God recognises moral facts that are independent of His will, making Him redundant as a moral foundation. The transcendental argument does not escape this dilemma; it simply relocates it at a higher level of abstraction, where it is easier to overlook but no less lethal to the position it is meant to support.
The third component is more empirical than philosophical. The moral intuitions that the transcendental argument is trying to protect, the intuitions that cruelty is objectively wrong, that fairness genuinely matters, that human suffering is not merely an inconvenience but a moral emergency, are shared by the overwhelming majority of human beings across cultures and across centuries. The cross-cultural convergence of basic moral intuitions, documented in research by developmental psychologists like Jonathan Haidt and evolutionary anthropologists like Joseph Henrich, is more consistent with those intuitions being deep features of human social cognition than with them requiring supernatural certification to count as valid. The intuitions survive the meta-ethical debate about their status because they are grounded in real facts about what kinds of beings we are and what kinds of conditions allow us to live well together. The question of whether those facts require a divine guarantor to be genuinely normative is a fascinating meta-ethical puzzle, but it does not affect the practical availability of moral reasoning to human beings who lack such a guarantor and who have been doing the reasoning quite effectively without one.
Anyone interested in how the secular moral framework responds to the strongest theological challenges, including the transcendental argument and the related claim that atheists have no basis for moral criticism, will find that the question of whether atheists can be moral without God is addressed at length in the linked essay.
The Borrowing and the Denial
The central claim of this essay can now be stated precisely. Religion did not author the moral standard by which human beings judge conduct. It inherited that standard from the evolutionary and social history of a highly cooperative species, developed and refined it through the same processes of reasoning and experience that produce all other human knowledge, and then, through an act of extraordinary intellectual appropriation, claimed authorship of a product it received rather than created. The borrowed morality was dressed in divine clothing and returned to its original owners as though it were a gift from outside rather than a reflection of something they had always possessed.
The evidence for this claim is visible everywhere in religious practice. Every time a believer reads a command to enslave prisoners of war and decides, correctly, that this does not represent timeless divine wisdom, they are applying a moral standard that predates and transcends their scripture. Every time a congregation reinterprets a text that prescribed capital punishment for adultery as an expression of a now-obsolete cultural context, they are using secular moral reasoning to edit the allegedly eternal word of God. Every time a theologian argues that the loving passages of the gospel represent the authentic core of Christian teaching while the passages calling for the destruction of enemies represent misunderstanding or hyperbole, they are performing a selection whose criterion is a moral intuition about love, dignity, and harm that they brought to the text from outside it. The selection is the proof. The standard does the selecting, and the standard is theirs, not the text’s.
This is not an accusation of bad faith. Most of the believers performing this editing are doing so honestly, motivated by a genuine desire to bring their faith into alignment with their moral understanding. That alignment is admirable; the misattribution of authorship is what requires correction. The moral understanding is the thing doing the aligning. The text is the thing being aligned. To claim that the text is the source of the moral understanding is to mistake the conclusion for the premise and the product for the process, which is precisely the kind of logical error that a tradition which takes itself seriously should be most anxious to avoid.
What would it look like to take the divine authorship claim seriously rather than applying the secular moral filter? It would look like accepting the slavery passages as binding moral instruction, the stonings as legitimate justice, the genocide commands as expressions of divine righteousness. It would mean treating every verse with the same deference and finding no principled basis for distinguishing the ones about love from the ones about conquest, because the text itself provides no such hierarchy and the authority claimed for the text is unconditional. No contemporary believer in any mainstream tradition actually operates this way, and the reason they do not is that their moral understanding, the understanding they share with every secular humanist who has ever argued against slavery or the subordination of women, tells them these passages are wrong. That moral understanding is doing precisely the work that it is claimed only God can do. The claim collapses on its own evidence.
The Stakes of Getting This Right
The consequences of misidentifying the source of our moral authority extend well beyond the abstract. When a society accepts that its moral framework is derived from divine command rather than from human reasoning about human flourishing, it introduces a category of moral claims that are in principle immune to rational revision. If a moral rule is divinely commanded, challenging it is not merely unpopular; it is transgression against the sacred order. The social cost of challenging it is not merely the ordinary cost of holding a minority view, which is manageable in a functioning liberal society, but the cost of being identified as a blasphemer, an apostate, or an enemy of God. This dynamic is why moral progress in societies with strong religious institutions has historically required either the painful reinterpretation of theological authority or the slow erosion of its social power, rather than simply the making of better arguments and the changing of minds.
When moral authority is grounded in human reasoning rather than divine command, a different set of dynamics applies. A moral rule that harms people can be challenged on the grounds that it harms people, and if the argument is good enough, the rule can be revised. The threshold for revision is the quality of the argument and the weight of the evidence, not the sanction of an institution whose authority is claimed to be supernatural and therefore unquestionable. This is more demanding in some ways: it requires the hard and unending work of argument rather than the relative simplicity of appealing to authority. But it is also more honest about what morality actually is, a human activity of working out, together, what we owe to one another and why, with no guaranteed answers and no celestial referee to end the game when the score is disputed.
The moral advances that make modern liberal societies tolerable places to live, the protection of civil liberties, the prohibition on torture, the recognition of equal rights regardless of sex, race, or sexuality, were not delivered by revelation. They were argued for, contested, won through sustained campaigns of political and intellectual pressure, and eventually encoded in law by institutions that were persuaded by argument rather than commanded by God. The process was imperfect, slow, frequently reversed, and still incomplete in ways that should make anyone comfortable with the current state of things uncomfortable. But it was recognisably a process of moral reasoning carried out by human beings who took seriously the question of what harm is, who it falls upon, and why it matters. Recognising it as such is not merely a point of philosophical accuracy. It tells us what we need to do when the current moral framework fails, as it inevitably will in various ways: we need better arguments and more honest engagement, not a purer obedience to authority, and certainly not a new revelation that arrives pre-approved by an institution with an interest in the answer.
Conclusion: The Standard Is Ours, and That Is Enough
The claim that without God there is no morality is not merely false. It is, on the available evidence, the reverse of the truth. The moral standard by which we evaluate conduct, including the conduct prescribed in scripture and endorsed by religious institutions, is a human standard, developed through human evolution, refined through human reasoning, and sustained through human commitment to consistency and compassion. Religion did not create it. Religion, at various points and in various forms, has expressed it, distorted it, institutionalised it, and obstructed it. But the standard itself is prior to any particular religious tradition, which is why it survives the collapse of any particular theological system with perfect equanimity and why it was available to the critics of religious institutions long before those institutions conceded the argument.
The Euthyphro dilemma establishes this at the level of pure logic: the claim that morality requires divine command generates either arbitrariness or redundancy, and no theologian in twenty-four centuries has found a third option. The selective reading of scripture establishes it at the level of practice: the very act of distinguishing the passages worth keeping from those that reflect ancient barbarism requires a moral standard that the scripture did not supply. The historical record of moral progress achieved against institutional religious opposition establishes it at the level of social history: the advances were made by those who reasoned their way to better conclusions, not by those who waited for ecclesiastical permission. The demonstrably flourishing secular societies of northern Europe establish it at the level of empirical evidence: the predicted moral collapse of societies without God has not occurred and shows no signs of occurring. And the straightforward evolutionary and developmental account of where moral emotions and moral reasoning come from establishes it at the level of biology and psychology: we had these capacities before we had these texts, and we exercised them in working out which texts to trust.
That conclusion is not a source of moral vertigo. It is a source of moral responsibility, which is considerably more useful. If the standard is ours, then its improvement is our work. There is no revelation to wait for, no authority to petition, no divine correction to hope will arrive and solve the problems that honest argument alone must address. This is demanding, but it is also honest about the situation human beings actually face. The moral authority has always resided with us, as the evidence of every edited scripture and every overturned theological consensus confirms. The task before us is not to acknowledge the divine origin of our moral authority but to accept the human responsibility that comes with recognising the authority has been ours from the beginning, and to exercise it with the seriousness and the humility that recognition demands.
Christopher Hitchens was right. Human decency is not derived from religion. It precedes it. The honest question is not whether we can sustain our moral life without God; we have been sustaining it, building it, and slowly improving it since long before the first scripture was written. The honest question is whether we are prepared to take full responsibility for that work, without the comfort of claiming that the standard came from somewhere else and the mistakes were someone else’s fault.
