I think it’s best to reserve the word “unethical” for behavior that violates the written standards of a profession, the word “unprofessional” for behavior that violates the unwritten standards of a profession, and the word “immoral” for behavior that violates the standards of God. Since there is worldwide dispute about what God demands of us, I typically suggest that we not use the word, “immoral.” Instead, if someone does something you disapprove of, you can say you don’t like it.
Still, I acknowledge that there is another sensibility, one that I agree with, that is often associated with the words “ethical” and “moral.” This might be described as not exploiting others, or adhering to something like the Golden Rule or the categorical imperative. General rules like these don’t work in practice, however, because one person’s idea of exploiting others is another’s idea of expecting them to pay their fair share or do their duty. As for the Golden Rule, there are many people who don’t wish to be treated as I do. And a rule that I would recommend for all occasions may be one that you’d just hate. I’ve resisted such declarations of morality because as soon as you agree that forcible rape is immoral, someone somewhere will tell you that masturbation is, too. And then you’re back to personal opinions.
For now, though, I am assuming that when people claim that a belief in God grounds their morality, they mean by morality their reluctance to abuse, exploit, or harm others. I readily agree that the sort of morality meant by a disinclination to masturbate is rooted in faith. But now I am disputing the idea that treating other people well—that morality—is based on a belief in God.
If a man refrains from raping women because it’s wrong to do so in the eyes of God, I don’t want that man anywhere near me. I like men who would not rape a woman whether it was wrong or not, simply because of the effect on the woman. If a woman refrains from beating a child because it is wrong, I don’t want that woman anywhere near my grandson. I don’t want him to have to cope with her rage or her experience of him as beating-worthy whether or not she acts on them. I don’t really think that people who believe that morality is based on religion construe themselves and others as rapacious, brutal sociopaths who needs strict rules to keep them in line. It’s a cute argument, but the truth is that people who believe that morality comes from God just haven’t thought it through. They associate good behavior with images of Jesus or passages in the Koran or the temple in which kindness was praised; they connect their good intentions with associated images.
Morality comes from empathy and identification, not faith. [Behavioral aside: People act morally in this sense as a result of reinforcement of prosocial behavior. The well-being of others becomes a conditioned reinforcer.] If you appreciate the harm done to others, and if you see them as members of your group (as objects of your concern), you won’t hurt them; you won’t want to hurt them. We learn empathy and identification by being empathized with and identified with, and we apply empathy and identification to others according to lessons we are taught about who is in our group and who is not. That’s why gang members can treat each other exceedingly well and outsiders exceedingly poorly—ditto for members of a religion. One way to understand the members of PETA is that they identify with animals almost as much as they identify with humans, so for them, it is immoral to mistreat a pig. I don’t know how I feel about that, because I definitely believe that we are pretty closely related to pigs, but eating them just doesn’t bother me. I know how I feel about other humans though. They are all in my group, objects of my concern.
If you pee in the pool and your dad reproaches you, you stop peeing in the pool when your dad’s watching you, but we don’t really consider that to be moral behavior. You’re worried about getting caught, not concerned with the well-being of the other swimmers. If someone who cannot possibly get caught goes to the trouble of getting out of the pool, drying off, getting to the bathroom, and returning to the pool, that’s what we mean by morality. It’s not moral if you act that way only when you’re being watched. If you believe in a God who watches everything you do, then far from being a basis for morality, the presence of God makes it impossible to be truly moral.
