The antithesis thus drawn, however, is but preliminary. After observing the fact that there is a science of vital actions normally carried on, which ignores abnormal actions, we have more especially to observe that the science of abnormal actions can reach such definiteness as is possible to it only on condition that the science of normal actions has previously become definite; or rather, let us say that pathological science depends for its advances on previous advances made by physiological science. The very conception of disordered action implies a preconception of well-ordered action. Before it can be decided that the heart is beating faster or slower than it should its healthy rate of beating must be learned; before the pulse can be recognized as too weak or too strong, its proper strength must be known, and so throughout. Even the rudest and most empirical ideas of diseases, pre-suppose ideas of the healthy states from which they are deviations, and, obviously, the diagnosis of diseases can become scientific only as fast as there arises scientific knowledge of organic actions that are undiseased. Similarly, then, is it with the relation between absolute morality, or the law of perfect right in human conduct, and relative morality which, recognizing wrong in human conduct, has to decide in what way the wrong deviates from the right, and how the right is to be most nearly approached. When, formulating normal conduct in an ideal society, we have reached a science of absolute ethics, we have simultaneously reached a science which, when used to interpret the phenomena of real societies in their transitional states, full of the miseries due to non-adaptation (which we may call pathological states) enables us to form approximately true conclusions respecting the natures of the abnormalities, and the courses which tend most in the direction of the normal. § 106. And now let it be observed that the conception of ethics thus set forth, strange as many will think it, is one which really lies latent in the beliefs of moralists at large. Though not definitely acknowledged it is vaguely implied in many of their propositions.
