It is often said that intuitive moralists in their reasonings are guilty of continually abandoning their principles by themselves appealing to the tendency of certain acts to promote human happiness as a justification, and the charge is usually accompanied by a challenge to show any confessed virtue that has not that tendency. To the first objection it may be shortly answered that no intuitive moralist ever dreamed of doubting that benevolence or charity, or in other words, the promotion of the happiness of man, is a duty. He maintains that it not only is so, but that we arrive at this fact by direct intuition, and not by the discovery that such a course is conducive to our own interest. But while he cordially recognises this branch of virtue, and while he has therefore a perfect right to allege the beneficial effects of a virtue in its defence, he refuses to admit that all virtue can be reduced to this single principle. With the general sentiment of mankind he regards charity as a good thing only because it is of use to the world. With the same general sentiment of mankind he believes that chastity and truth have an independent value, distinct from their influence upon happiness. To the question whether every confessed virtue is conducive to human happiness, it is less easy to reply, for it is usually extremely difficult to calculate the remote tendencies of acts, and in cases where, in the common apprehension of mankind, the morality is very clear, the consequences are often very obscure. Notwithstanding the claim of great precision which utilitarian writers so boastfully make, the standard by which they profess to measure morals is itself absolutely incapable of definition or accurate explanation. Happiness is one of the most indeterminate and undefinable words in the language, and what are the conditions of “the greatest possible happiness” no one can precisely say. No two nations, perhaps no two individuals, would find them the same.(67) And even if every virtuous act were incontestably useful, it by no means follows that its virtue is derived from its utility.
