Moral theories often conflict with our moral intuitions; they are often counter-intuitive. Explanations, theories, or beliefs are counter-intuitive if they violate our ordinary, common-sense view. For example, it’s counter-intuitive to suppose that physical reality is illusory, although there is no way to demonstrate this isn’t the case. Similarly, it’s counter-intuitive to suppose the keyboard upon which I type is moving, although the keyboard, earth, solar system, galaxy, and entire universe move! This demonstrates that non-moral intuitions are often mistaken.
Surely our moral intuitions are sometimes wrong too. To see this point, consider some moral beliefs and practices once thought to be consistent with our moral intuitions: human slavery; the inferiority of women; human sacrifice; debtor’s prisons; dueling; torture; witch burning; etc. Since most of us now believe these practices are wrong, we must admit that our former moral intuitions were mistaken. But isn’t it possible that many of our present moral intuitions will be rejected in the future? For instance, can we not imagine that in the future meat-eating or solitary confinement will be thought barbaric? And if we reject a present intuition at some later date, then they aren’t sacrosanct now.
Thus the mere fact that a theory violates our moral intuitions isn’t necessarily a reason to reject the theory; we might reject our intuitions instead. How do we resolve the dispute between the two? One of the ways of resolving the dispute between moral intuitions and moral theories is to achieve what contemporary philosophers call reflective equilibrium, which calls for a balance between moral intuitions and theories. If a theory radically contradicts our moral intuitions, then the theory should probably be rejected. On the other hand, id the theory has a number of explanatory advantages and only slightly challenges our moral intuition, then the intuition should probably be rejected.
But most classic moral theories aren’t generally counter-intuitive. In fact, they are classic because they explain so much of our ordinary moral consciousness. Nonetheless, since no theory is perfect, almost any proposed moral theory generates some counter-intuitive results. Perhaps this reveals to each of us, that we don’t have a privileged moral status. If our moral status were privileged, then we could measure any proposed theory against it. But we will assume that our moral status and intuitions aren’t privileged. They don’t provide unique insight into moral truth. If our moral status were privileged this investigation would be irrelevant, since we would already possess moral truth. We reject this claim.
The same issue applies when we turn from explaining morality to justifying it. Contemporary philosophers offer three basic kinds of justification for morality. Some, following Plato and Hobbes, argue that morality is based in self-interest. Others, following Hume and Mill, suggest that morality rests upon some sentiments, emotions, or sympathies we happen to have. Others, following Kant, insist that morality is grounded in reason. In addition to these philosophical justifications, some metaphysicians and theologians maintain that the source of morality rests in the metaphysical order. Whatever our moral intuitions about moral justification, we assume that these intuitions aren’t privileged.
