Christian historian Dr. Wallace Marshall and I are debating whether or not enough evidence points to the existence of a god. For background and format, and Dr. Wallace’s opening statement, see entry one. For subsequent entries, see index.

We’ve covered the cosmological argument for god and the argument from evil or indifference against god (which Marshall just concluded with his final answer on that), and now are moving on to his “Moral Argument” for the existence of God. Here is Marshall’s elaboration of it.


That the Evidence Points to God (X)

by Wallace Marshall, Ph.D.

My second argument for theism is the Moral Argument, which runs as follows:

  1. If God does not exist, objective moral values and duties do not exist.
  2. Objective moral values and duties exist.
  3. Therefore, God exists.

To head off some common misunderstandings, note that the argument doesn’t claim that God needs to inform us, say in a revelation of some kind, about what’s right and wrong. Nor is it claiming that people need to believe in God in order to behave ethically. Rather, it’s about moral ontology: what morality is, and what seems necessary to ground it. Finally, note that each of the premises finds support among atheists.

Philosophers who analyze our moral experience have discovered that moral language and its connotations are quite distinctive. It’s markedly different from how we talk about things like etiquette, convention, taste, preferences or aesthetics. As John Mackie put it in his classic 1977 book, Ethics, moral experience seems to contain “qualities or relations of a very strange sort, utterly different from anything else in the universe.” [1]

Philosophers of morality spend a lot of time analyzing how people use moral words—“ought,” “duty,” “rights,” “justice,” etc. What ideas or beliefs are implied by the way people use these terms? What sentiments do people experience when they’re using them? If a proposed theory doesn’t fit well with the way people use and experience moral language, then the theory is likely to be rejected. Philosophers will say, “Well if that’s how your theory is defining moral terms, then you’re not really talking about morality. You’re using the same words but you’re talking about something else.” Such theories “cease to participate competently” in moral discourse, and are therefore ruled out. They may be good theories of something else, but they’re not satisfactory theories of morality.

Let me point out three significant features that emerge from an analysis of moral experience:

  1. “Oughtness.” When we say that an action is morally wrong, we mean that the person to whom we are speaking is prohibited from doing it, regardless of whatever his personal interests, desires and projects might be. Of course we don’t always use the word “ought” in this moral sense. Often we’re just using a consequential ought (“You ought to leave now if you want to get home before dark”). Here there’s nothing moral: it’s simply a piece of advice: If you want X, you should do Y, because Y is the most likely way of getting X. The moral ought implies obligation; the consequential ought doesn’t.
  2. Personal responsibility and the consequent legitimacy of praise and blame, and of moral indignation against someone who has committed a terrible evil.
  3. The universality of at least some moral standards: that some things, or at least one thing—the paradigmatic “torturing a little child for fun”—are morally evil for every human being in every context throughout history.

I will summarize those three beliefs with the short statement of Premise 2, “Objective moral values and duties exist,” where “objective” means, “something that would be wrong even if everyone on the planet thought it was okay.”

The three moral convictions listed above would seem to easily qualify for what philosophers call “properly basic” beliefs, that is, beliefs that are formed naturally in a normal cognitive state, and that we should accordingly maintain in the absence of some “defeater.”

Philosophers known as “moral-error theorists” recognize that almost everyone has these moral beliefs, but they think the beliefs are mistaken. As atheist Richard Joyce, one of the most prominent moral philosophers in the English-speaking world laments, the universe “just doesn’t contain the requisite properties (goodness, wrongness, etc.) necessary to render any of [our moral judgments] true.” [2]

Premise 1, then, is the claim that atheism, if true, constitutes a defeater for Premise 2. If God doesn’t exist, our moral convictions are simply then the biological and sociological spinoff of an evolutionary process whose only aims are survival and reproduction, and whose ultimate ground is simply matter and energy, which of course are impersonal and morally indifferent. Humans have the moral convictions they do because at some point in our evolutionary history they were probably useful to survival and reproduction. [3] They may still be, or they may no longer be, but the only “ought” they would qualify for would be the consequential ought, namely: “If you want your species to continue to survive and grow, you may want to continue behaving in these ways, unless it’s seems pretty clear to you that some of them have outlived their evolutionary usefulness.”

Granted, on atheism, we might still develop an objective science of how to attain various societal conditions that a wide majority of people find to be conducive to their happiness; say, the flourishing of all humans or sentient creatures, or a society people would hypothetically “vote for” if they didn’t know in advance where they would end up being placed (Rawls’ “Veil of Ignorance”).

But such systems will be conditional on the agreement of the players who have signed up for the game, so to speak. They have no moral basis for obligating or condemning aberrant individuals or groups who choose to play a different game —thieves and gang members, serial killers, pedophiles and sadists; or a group like the Nazis that rejects the extensive model of human/sentient flourishing in favor of an intensive model that favors the flourishing of the highest types. Of course there would still be a pragmatic reason for coercing conformity from such people, but it wouldn’t be a moral reason.

Dr. Carrier may have another naturalistic moral philosophy to present, of course, which I’ll be happy to hear and comment on.

If God does exist, however (not “gods,” which if necessary I will show cannot do the job), then the ultimate foundation of existence is personal and moral. This wouldn’t solve all our ethical problems, of course, but it would (1) give us confidence that our fundamental moral convictions are not illusory but are rooted in the framework of a moral universe; and (2) provide a moral basis for obligating conformity (the moral “ought”).

Plato’s “Euthyphro Dilemma” is the most common objection to grounding morality in God, but I think it is easily answered, as I will show if Dr. Carrier wishes to bring it forward.

What about “biting the bullet” and rejecting both God and objective morality together? Here I think atheist philosopher Louise Antony has a compelling reply: “Any argument for moral scepticism will be based upon premisses which are less obvious than the existence of objective moral values themselves.” [4]
