Utilitarianism tells us that actions are morally right and good if and to the extent that they add to human happiness or diminish human unhappiness. And—or, perhaps, therefore—it also tells us that the best action a person can perform is that which of all the possible actions open to him is the one which makes the greatest positive difference to human happiness. Moreover, as everyone will also remember, utilitarianism further tries to tell us, perhaps intending it as a corollary of that first, main claim, that the motive for an action has nothing to do with its moral rightness or goodness. (This, of course, is just a philosopher's excessive and incorrect way of making the platitudinous point that one may do the wrong thing for the right reason and the right thing for the wrong reason.) But even if, as utilitarians, we accepted the dubious corollary, it would not follow, as many have thought, that utilitarians have no moral interest in motives. For unless, absurdly, a utilitarian believed either that there was never more than a fortuitous connection between on the one hand what we intended to do and on the other what we did and the consequences of what we did, or that, if there were such connections, we could not know of them, he must believe, as a moralist, that the best motive a person can have for performing an action is likely to be the desire to produce the happiest result. Indeed, utilitarians ought to be morally committed, it would seem, to trying to find out as much as they can about the consequences of our actions, e.g. what connections exist, if any, between how we raise children and what sort of adults they grow up to be.
