Bad Bongo!: Are Chimps Moral? (Part 3 of 3)

This entry is part 2 of 3 in the series Bad Bongo

Last time (Part 1 & Part 2), Beckwith & Koukl demonstrated how the evolutionary approach to explaining morality actually denies it. Now, for an even bigger problem…

Why Should I?

This third observation uncovers the third and most serious objection to the idea that evolution is adequate to explain morality. One question can never be answered by any evolutionary assessment of ethics: Why ought I be moral tomorrow?

One of the distinctives of morality is its ‘oughtness,’ its moral incumbency. Assessments of mere behavior, however, are descriptive only. Since morality is essentially prescriptive — telling what should be the case as opposed to what is the case — and since all evolutionary assessments of moral behavior are descriptive, then evolution cannot account for the most important thing that needs to be explained: morality’s ‘oughtness’.

One question really needs to be answered: Why shouldn’t the chimp (or a human, for that matter) be selfish? The evolutionary answer might be that when we’re selfish, we hurt the group. That answer, however, presumes another moral value, that we ought to be concerned about the welfare of the group. But why should that concern us? They would say ‘because if the group doesn’t survive, then the species doesn’t survive.’ But why should we care about the survival of the species?

Here’s the problem. The responses intended to explain morality ultimately depend on some prior moral notion to hold them together. Based on an evolutionary view, it is difficult to explain why we should not be selfish, or steal, or rape, or even kill tomorrow without smuggling morality into the answer.

The evolutionary explanation disembowels morality, reducing it to mere descriptions of conduct. The best the Darwinist explanation can do — if it succeeds at all — is explain past behavior. It cannot inform future actions. But prescription, not description, is the essence of morality. As we have seen, evolution may be one explanation for the existence of conduct we choose to call moral, but it gives no reason why we should obey any moral rules in the future. If one countered that we have a moral obligation to evolve, then I’ve won my point. If we have moral obligations prior to evolution, then evolution itself can’t be their source.”

Hah! I love it.

Earlier in the chapter, the authors point out:

Evolutionists may be right when they say that we’re not compelled to adopt the morality of evolution. The danger of social Darwinism, however, is not that society must adopt the law of the jungle but rather that it is allowed to. The exploitation of the weak by the strong is morally benign according to Wright’s evolutionary view of morality.

What Darwinists cannot do is give us a reason why we ought not simply copy nature and destroy those who are weak, unpleasant, costly, or just plain boring. If all moral options are legitimate, then it’s acceptable for the strong to rule the weak. No moral restraints would protect the feeble, because moral restraints simply wouldn’t exist….

Bongo is not a bad chimp; he’s just a chimp. No moral rules apply to him. Eat the banana, Bongo.”
