 Facts about the nature of moral inference and moral reasoning may have important direct implications for moral theory. For instance, it might be taken to be a condition of adequacy of any moral theory that it play a practically useful role in our efforts at self-understanding and deliberation. It should be deliberation-guiding (Richardson 2018, §1.2). If this condition is accepted, then any moral theory that would require agents to engage in abstruse or difficult reasoning may be inadequate for that reason, as would be any theory that assumes that ordinary individuals are generally unable to reason in the ways that the theory calls for. J.S. Mill (1979) conceded that we are generally unable to do the calculations called for by utilitarianism, as he understood it, and argued that we should be consoled by the fact that, over the course of history, experience has generated secondary principles that guide us well enough. Rather more dramatically, R. M. Hare defended utilitarianism as well capturing the reasoning of ideally informed and rational “archangels” (1981). Taking seriously a deliberation-guidance desideratum for moral theory would favor, instead, theories that more directly inform efforts at moral reasoning by we “proletarians,” to use Hare’s contrasting term.
