We must discriminate. Morality is not relative to our inclinations and desires, because those often do not rightly represent our own true welfare, still less the general welfare. Happiness is desirable whether our impulses are adjusted so as to aim for it or not. Nor is morality relative to our opinions; an act may be wrong though the whole world proclaim it right. It is a matter not of opinion but of fact whether an act is going to bring the greatest attainable welfare or not. However biased and shortsighted we may. be, the consequences of acts will be what they will be. In a very real sense, then, morality is objective; it is valid whether we recognize its validity and want it or not. It represents our needs more truly than our own wills, and thus has a greater authority, just as the rules of dietetics are not a matter of appetite or whim, but have a rational authority over our caprices. Morality is not, like imagination, something we can shape at will; it is imposed upon us from without, like sensation. Its development is predetermined by the structure of human nature and its environment; we do not invent it, we accept it. [Footnote: Cf. Cudworth (ca. 1688), Treatise, chap, n, sec. 3: "It is so far from being true that all moral good and evil, just and unjust, are mere arbitrary and factitious things, that are created wholly by will, that (if we would speak properly) we must needs say that nothing is morally good or evil, just or unjust, by mere will without nature, because everything is what it is by nature, and not by will." A good recent discussion bearing upon the question of the relativity of morality will be found in Santayana's Winds of Doctrine, pp. 138-154.] But although imposed upon our restive impulses, it is not imposed by any alien and arbitrary will. It is imposed by the same cosmos that set our consciousness into relation with a given kind of body in a given world. Submission to it is simply submission to the laws of our own natures. Lasting happiness can be found only in certain ways; we must make the best of it, but it is for our own good that we obey. Morality is relative to our organic needs and particular environment. It is a function of human nature, varying with its variations. A different race of beings on another planet might have to have a very radically different code. Ours is a distinctively human code, bearing the earmarks of our humanity and stamped with the particular nature of our earth-life.
