"The chief object of medical science is to relieve suffering and to save life: you must, therefore, anxiously watch the action of remedies and, by constantly noting down the effects of treatment, learn to appreciate its merits and apply it when required. Nor is this an easy task; some indeed have vainly imagined that the method of treating or curing disease could be compressed within the limits of a few short directions made easily deducible from some general principles and easily applicable in any particular case; but it is not so. Gentlemen, we have as yet discovered no such general principles to serve as guides. This discovery presupposes a knowledge of the laws and relations of the vital powers far beyond what we now possess: no, we must toil onward by a much more {180} laborious and circuitous route and must commence by making ourselves thoroughly masters of a vast number of individual cases, assisted by the observations and the writings of practical men; we may afterward proceed to arrange our knowledge, to classify it so as to render it more available; analogy and induction are here our only or at least our most valuable guides, and they will seldom fail to instruct us how to act when properly consulted." While recognizing all the difficulties of medical practice and the essential individualization of all its problems, Dr. Graves had little or no patience with the skeptic who thought that medicine could accomplish but little for the cure of many ailments. He said once before the Medico-Chirurgical Society: "Many, indeed, aiming at acquiring the character of medical skeptics, think they exhibit proofs of superior discrimination when they, with apparent candor, make the confession that the more they see the less confidence they have in the resources of medicine. This confession should be interpreted not as a reproof of our art, but as a testimony of the want of skill of the would-be philosophical asserter of so false a proposition. No, God be praised, our predecessors have not toiled in vain; the anxious experience of ages has not been recorded to no purpose; our art is in truth boundless in resources and, when applied with ability, most successful. There are, indeed, some acute and many chronic diseases which baffle our powers of diagnosis, and defy our modes of treatment; such appear to be, however, not numerous when compared with the great mass of cases capable of cure or alleviation. The medical skeptic, however acute his powers of reasoning may be, and however he may labor to render plain subjects obscure and direct facts ambiguous, can never rob the good practitioner of the {181} pure, the inward joy he feels when conscious that he has snatched a patient from the jaws of death."
