Whenever I argue that morality is subjective I encounter people who regard that idea as so unpalatable that they are determined that we must find a scheme — somehow, anyhow — in which morality can be regarded as objective. The term “subjective” has such negative connotations. I argue here that such connotations are not justified.
If we ask what morality actually is, the only plausible answer is that morality is about the feelings that humans have about how we act, particularly about how we treat each other. This was proposed by the greatest ever scientist, Charles Darwin, who in Chapter 3 of his Descent of Man stated that that “moral faculties of man have been gradually evolved” and added that “the moral sense is fundamentally identical with the social instincts”.
He explains that in social animals such instincts would take the form that in each individual:
… an inward monitor would tell the animal that it would have been better to have followed the one impulse rather than the other.
The world’s greatest philosopher, David Hume, had earlier arrived at the same conclusion. In his An Enquiry Concerning the Principles of Morals Hume explained that “morality is determined by sentiment”, saying that “in moral deliberations” the “approbation or blame … cannot be the work of the judgement”, but is instead “an active feeling or sentiment”.
In these sentiments then, not in a discovery of relations of any kind, do all moral determinations consist. . . .
… we must at last acknowledge, that the crime or immorality is no particular fact or relation, which can be the object of the understanding, but arises entirely from the sentiment of disapprobation, which, by the structure of human nature, we unavoidably feel on the apprehension of barbarity or treachery.
No-one has ever suggested any alternative account of morals that makes the slightest sense. The main alternative suggestion is that morality is about the values and feelings of gods, rather than of humans, but we have neither hide nor hair of any gods, whereas we know that humans exist and have evolved.
Given our evolutionary past, in a highly social and cooperative ecological niche, we will inevitably have been programmed with moral feelings, feelings about how we act towards each other. Thus morals are rooted in human values and in what we like and dislike. That makes morals, at root, subjective, since the term “subjective” means “based on or influenced by personal feelings, values and opinions”.
Whether an act is regarded as “morally good” or “morally bad” must, in the end, be a statement about how humans feel about the matter. No viable alternative has ever been proposed. Continue reading
