His income is limited by these personal conditions, modified only by the possession of some exceptional skill and the accidents of popularity or environment. The engrossing character of his occupation hinders him from the experience that justifies outside speculation with acquired capital and restrains him from participation in outside ventures which require freedom both of time and thought. He cannot well add another string to his bow. The results of combination in trade and the income from professional labor are issues from distinct and opposite sources and have no right to be compared or made the subject of invidious reflection. A number of lawyers, each an expert in a special department, may form a partnership, occupy a common office, each helping the other, the emoluments going to the common fund. This is a sort of combine. But the time is not yet ripe, and probably will never come, for the incorporation of a great Medical Trust, with the names of a specialist in eye, ear, throat, nose, lungs, liver, sphincter ani, corns and fallopian tubes, and so on to the minutest subdivision, with the addition of some general practitioners and apothecaries, displayed around the casings of some common front door, to scoop in the community and pool the receipts on a graded tariff. Trade is essentially selfish and works for the individual. “If you don’t work for number one, number two will be working for you.” The accumulation of money is neither end nor contingent in professional life. The pursuit and application of medical science are on the higher level with the learning of jurists, scientists, educators and literateurs, whose mission is the unselfish search for knowledge for the immediate benefit of mankind and the advance of civilization.
