A lot of the philosophers and thinkers I respect are coming around to the view that there can be an “objective” morality, which I take to mean this: rational consideration of the world’s facts will reveal criteria whereby things can be seen objectively as either right or wrong. It may be hard to get those facts, but once you do the moral path would, it seems, be clear.
I still don’t accept this, and for the reason that, unlike science, morality also includes “add ons”. That is, after you divine the consequences of any action, one still has to add on the stipulation that those consequences comport with some standard of “rightness” or “wrongness.” Now people like Sam Harris claim that those standards are objective, too (his is “does an act increase general well being?”) but I don’t think it’s so simple, and neither do other philosophers.
In contrast, science has no add-ons. Once you find out that birds descended from dinosaurs, nothing else need be added to make this an objective truth (provisional truth, of course!).
To see the problem of objective morality, consider this question:
“Is it right or wrong to eat meat, even if the animals are humanely raised?”
How do you answer this, even using the criterion of “well being”? Whose well being is being assessed? Humans, animals, or both? And how do you trade off human with animal well-being? Is it immoral to kill a mosquito just because it bites you? What if the mosquito lives in a place where such creatures are disease-free? Does your annoyance trump the life of an animal? It doesn’t for the Jains.
Any criterion of “moral action,” including “well being,” will end up so nebulous that in many cases it becomes useless—as in the above.
Let me hasten to add that I agree with Sam’s view that morality—although I prefer to avoid the terms “moral or immoral”—will nearly always jibe with what increases general well being. Like him, I am a consequentialist, and favor those actions that increase well being.
Where we differ is that I don’t think the criterion of “well being” is an objective one. It is a subjective choice, and can’t be chosen based on a scientific study of nature. (In contrast, the molecular structure of benzene can be objectively discerned.) And “well being” is sufficiently nebulous that it can be stretched to cover everything, in which case it becomes useless. Is it moral to torture a prisoner if there is a 1/1000 chance that he will reveal where a bomb is planted that will kill 100,000 people? You could argue, based on well being, that torture is not only mandated, but required, in this case. But one could also argue that “well being” includes the structure of a society, and it’s not good to create a society in which anyone can be tortured.
I’m just working out some thoughts here, so don’t take this as a final pronouncement. But I still have difficulty in seeing how “morality” can be objective in any sense. Once you decide on a criterion, of course, then all else follows. But it is the case that “well being” always comports with what our notion of morality is? And if it doesn’t, should we revise our notion of morality to bring it in line with “well being”? Or, if you agree that morality is objective, do you have some criterion other than well being?
But I emphasize again, that, as a consequentialist and determinist, I don’t favor the notion of “moral responsibility,” which I see as inimical to needed legal reforms. I would favor, instead, using the term “actions that are either good or bad for society.” This still leads to punishment on the grounds of keeping bad people out of society, as well as rehabilitating them and deterring others. But it eliminates the notion of retributive punishment, which in my view adds nothing to society.
Finally, it’s clear that under the standard of “general well being,” nearly all of us would be acting morally by giving a third of our income to the poor and starving people of the world. Yet we don’t. Are we then immoral? Or are we going to selfishly argue that well being is actually maximized if we’re able to keep as much of our money as we want, and bestow its largesse on our family and friends?
