Summary by David BaggettIn this chapter Evans raises and attempts to answer several common objections to Divine Command Theory. This post will cover the last four objections discussed.
The Prior Obligations Objection
Wainwright calls this objection the Cudworth objection, since it can be found in the writings of Ralph Cudworth. It’s rooted in the worry that DCT is too narrow and does not account for all genuine moral obligations. A full-fledged DCT holds that all moral obligations are divine commands. The prior obligations objection argues that there must be some moral obligations that are not grounded in divine commands because they hold antecedently to or independently of divine commands. Specifically, the claim is that humans have a moral obligation to obey God. This obligation is not itself grounded in God’s commands. There’s a prior obligation to obey God that explains why God’s commands can create new obligations. So there must be some moral obligations other than those that are created by God’s commands.
Defenders of DCT could say that these “prior obligations” to obey God are not actual obligations but just hypothetical ones: To say that we have a prior obligation to obey God is just another way of saying that we are obligated to obey God if God issues commands, but there is no actual obligation until a command is issued. The conditional proposition itself can be understood as simply spelling out the meaning of the claim that God has moral authority. To say that God has moral authority is just to say that he has the right to issue commands that ought to be obeyed. The sense of prior oughtness should not cause the DCT’ist worry, Evans thinks.
Notice, too, that this objection could apply to any moral theory, but such objections are wrongheaded. But the critic might object and suggest there is nothing hypothetical about the fact that we ought to obey God. It’s a standing obligation, not a hypothetical one. But to this Evans replies by reminding readers of his earlier distinction between sorts of ought statements—not all of them are moral obligations. We may even have moral reasons to obey God without those reasons constituting moral obligations.
One final reply Evans offers is this, which can supplement what’s already been said: perhaps, since the Bible does command us to obey God, God can convert the antecedent fact that humans ought to obey God’s commands into an actual moral duty, in what Evans calls a “bootstrapping” manner. On this view it is both true independently of God’s commands that one ought to obey God, but also true that “one ought to obey God” is in fact a moral obligation, because God has commanded us to keep his commands.
At worst, the objection would show that some obligations aren’t rooted in God’s commands, whereas others may be.
The Supervenience Objection
Murphy offers a version of this objection. It’s directed against an identity version of DCT, according to which God’s commands just are moral obligations. God’s prerogative in issuing commands, combined with an identity version of DCT, Murphy argues, entails the falsehood of the supervenience of the moral on the nonmoral. The idea behind this notion of supervenience is that the moral properties of things are supposed to be fixed by their non-moral properties. Moral properties, such as being obligatory, do not “float free of their other properties. So it can’t be the case that two actions are exactly alike except that one of the acts is morally obligatory and the other is not obligatory. Evans agrees with Murphy on this, and that if DCT entailed the falsehood of supervenience, that would be a problem for DCT.
Now, why does supervenience appear to be threatened? Because if God has discretion in his commands, then there could be two possible worlds exactly alike in their natural features, but in which God gives different commands. If moral obligations are determined by God commands, then it follows that actions in one of those worlds will be exactly like those in the other except for being morally obligatory. But this violates the supervenience of the moral on the non-moral.
It is true there’s a difference in the two situations: in one world God issues one command, and in the other a different command. But if God’s commands are moral obligations (on the identity thesis), the difference is a moral difference, but there’s no difference in nonmoral or natural properties, and thus a violation of supervenience.
Now, one response might be to reject divine discretion here, but Evans isn’t willing to do that. A second possible reply is to appeal to weak supervenience rather than strong supervenience. According to strong supervenience, “property x supervenes on property y” = a claim that in any possible world whatever has property y will also have property x. On weak supervenience, instead, “property x supervenes on property y” = it is necessarily the case that anything that has property y in some particular world will also have property x in that world. Since weak supervenience confines its requirement to a single possible world, Murphy’s transworld constraint is removed and supervenience is easier to satisfy. But Evans doesn’t go that route, opting instead for a way to satisfy both strong and weak supervenience.
To do so, Evans points out the distinction between non-moral properties and natural properties. There may be non-moral but supernatural properties: such as the property of being pleasing to God—in each situation, what it pleases God to do might be different. So there might be a difference in nonmoral properties after all, and supervenience is thereby preserved.
Consider two situations identical in all their natural properties, but God commands X in one of them but not the other (either in different worlds or in the same world). The command/noncommand is a moral property, but other supernatural properties are non-moral, such as: “being pleasing to God” or “being preferred by God.” This preserves the supervenience intuition: “no difference in moral properties without some difference in non-moral properties.”
Mysterious Relationship Objection
What is relation between divine commands and moral obligation? Three possibilities are:
- God’s commands are the cause of moral obligations.
- Moral obligations supervene on God’s commands.
- God’s commands are identical to moral obligations.
Having discussed identity and supervenience variants of DCT, Evans considers a causal version. Murphy argues that the problem with a causal version of DCT is that such a view does not allow for God’s commands to be at least partially constitutive of one’s reasons for actions. It’s true that if God commands us to do X, then we are obligated to do X, and thus have reason to do it. But it’s not God’s command that gives us that reason. A bully who threatens to beat you up unless you do X gives you a reason to do X, but the bully doesn’t have moral authority over you.
In reply, Evans suggests that the proponent of a causal version of DCT should say that it is the fact that God has the requisite authority that gives him the causal power to establish moral obligations. The special sort of causation at play is the authority of God that makes God different from the bully.
Recipients of God’s commands, according to some critics, must know that the commands come from God; otherwise no obligation is generated. I may be obliged to loan a car to my friend to whom I owe a favor, but an anonymous note saying to leave my car with its keys available produces no duty to do so. Likewise with God’s commands if we don’t know where they came from.
How does Evans reply? He rejects the idea that for God to successfully communicate a command to humans, he must communicate the command in such a way that it is obvious that the command comes from God. Two helpful distinctions can be brought to bear here: (1) We must distinguish between the recognition of a moral obligation and the recognition of the moral obligation as a divine command; and (2) one must distinguish a recognition of a moral obligation from an explanation of the existence of a moral obligation.
Believers and unbelievers alike can recognize various moral obligations. It might be a function of God’s grace for God to conceal that he’s behind obligations initially in order to mitigate judgment on those who disregard them.
