A. The matters entrusted to their keeping are the most important of all earthly possessions; for they are life itself, and, along with life, health, the necessary condition of almost all temporal enjoyment. No other class of men is entrusted with more weighty earthly interests. Hence the physician's responsibility is very great; hence the common good requires that he be eminently faithful and conscientious. B. With no other class of men does the performance of duty depend more on personal integrity, on conscientious regard for the higher law of morality than with the Doctor. For the Doctor's conduct is less open to observation than that of other professions. The lawyer may have many temptations to act unjustly; but other lawyers are watching him, and the courts of justice are at hand to check his evil practices. As to the judge, he is to pronounce his decisions in public and give reasons for his ruling. The politician is jealously watched by his political opponents. The public functionary, if he is unjust in his dealings, is likely sooner or later to be brought to an account. But the physician, on very many occasions, can be morally sure that his conduct will never be publicly scrutinized. Such is the nature of his ministrations, and such too is the confidence habitually reposed in his integrity, that he is and must be implicitly trusted in matters in which, if he happens to be unworthy of his vocation, he may be guilty of the most outrageous wrongs. The highest interests of earth are in his hands. If he is not conscientious, or if he lets himself be carried about by every wind of modern speculations, he can readily persuade himself that a measure is lawful because it is presently expedient, that acts can justly be performed because the courts do not punish them; and thus he will often violate the most sacred rights of his patients or of their relatives. Who has more frequent opportunities than a licentious Doctor to seduce the innocent, to pander to the passions of the guilty, to play into the hands of greedy heirs, who may be most willing to pay him for his services? No one can do it more safely, as far as human tribunals are concerned. As a matter of fact, many, all over this land and other lands, are often guilty of prostituting their noble profession to the vilest uses. The evil becomes all the more serious when false doctrines are insinuated, or publicly advocated, which throw doubt upon the most sacred principles of morality. True, the sounder and by far the larger portion of medical men protest against these false teachings by their own conduct at least; but it very frequently happens that the honest man is less zealous in his advocacy of what is right than is the propagandist of bold speculations and dangerous new theories in the spreading of what is pernicious.
