Nevertheless the general notions of health, disease, justice, artistic culture are of great importance: Not, however, because this or that case may be brought exhaustively under a single head and its specific traits shut out, but because generalized science provides a man as physician and artist and citizen, with questions to ask, investigations to make, and enables him to understand the meaning of what he sees. Just in the degree in which a physician is an artist in his work he uses his science, no matter how extensive and accurate, to furnish him with tools of inquiry into the individual case, and with methods of forecasting a method of dealing with it. Just in the degree in which, no matter how great his learning, he subordinates the individual case to some classification of diseases and some generic rule of treatment, he sinks to the level of the routine mechanic. His intelligence and his action become rigid, dogmatic, instead of free and flexible. _Moral_ goods and ends exist only when something has to be done. The fact that something has to be done proves that there are deficiencies, evils in the existent situation. This ill is just the specific ill that it is. It never is an exact duplicate of anything else. Consequently the good of the situation has to be discovered, projected and attained on the basis of the exact defect and trouble to be rectified. It cannot intelligently be injected into the situation from without. Yet it is the part of wisdom to compare different cases, to gather together the ills from which humanity suffers, and to generalize the corresponding goods into classes. Health, wealth, industry, temperance, amiability, courtesy, learning, esthetic capacity, initiative, courage, patience, enterprise, thoroughness and a multitude of other generalized ends are acknowledged as goods. But the _value_ of this systematization is intellectual or analytic. Classifications _suggest_ possible traits to be on the lookout for in studying a particular case; they suggest methods of action to be tried in removing the inferred causes of ill. They are tools of insight; their value is in promoting an individualized response in the individual situation. Morals is not a catalogue of acts nor a set of rules to be applied like drugstore prescriptions or cook-book recipes. The need in morals is for specific methods of inquiry and of contrivance: Methods of inquiry to locate difficulties and evils; methods of contrivance to form plans to be used as working hypotheses in dealing with them. And the pragmatic import of the logic of individualized situations, each having its own irreplaceable good and principle, is to transfer the attention of theory from preoccupation with general conceptions to the problem of developing effective methods of inquiry.
