When, however, it is entered as a profession, as a serious and difficult fine art, there are few employments more satisfying. All over the country thousands of men and women are following it with a passionate devotion which takes little account of the income received. A trade aims primarily at personal gain; a profession at the exercise of powers beneficial to mankind. This prime aim of the one, it is true, often properly becomes a subordinate aim of the other. Professional men may even be said to offer wares of their own--cures, conversions, court victories, learning--much as traders do, and to receive in return a kind of reward. But the business of the lawyer, doctor, preacher, and teacher never squares itself by equivalent exchange. These men do not give so much for so much. They give in lump and they get in lump, without precise balance. The whole notion of bargain is inapplicable in a sphere where the gains of him who serves and him who is served coincide; and that is largely the case with the professions. Each of them furnishes its special opportunity for the use of powers which the possessor takes delight in exercising. Harvard College pays me for doing what I would gladly pay it for allowing me to do. No professional man, then, thinks of giving according to measure. Once engaged, he gives his best, gives his personal interest, himself. His heart is in his work, and for this no equivalent is possible; what is accepted is in the nature of a fee, gratuity, or consideration, which enables him who receives it to maintain a certain expected mode of life. The real payment is the work itself, this and the chance to join with other members of the profession in guiding and enlarging the sphere of its activities. The idea, sometimes advanced, that the professions might be ennobled by paying them powerfully, is fantastic. Their great attraction is their removal from sordid aims. More money should certainly be spent on several of them. Their members should be better protected against want, anxiety, neglect, and bad conditions of labor. To do his best work one needs not merely to live, but to live well. Yet in that increase of salaries which is urgently needed, care should be used not to allow the attention of the professional man to be diverted from what is important,--the outgo of his work,--and become fixed on what is merely incidental,--his income. When a professor in one of our large universities, angered by the refusal of the president to raise his salary on his being called elsewhere, impatiently exclaimed, "Mr. President, you are banking on the devotion of us teachers, knowing that we do not willingly leave this place," the president properly replied, "Certainly, and no college can be managed on any other principle." Professional men are not so silly as to despise money; but after all, it is interest in their work, and not the thought of salary, which predominantly holds them.
