He makes known to us what is right and wrong. He informs every one of us, by the voice of reason itself, that He requires us to do the right and avoid the wrong. He has implanted in us the sense of duty to obey that law. If we do so, we lead worthy lives, we please Him, and, in His goodness, He has rewards in store.

But can He be pleased with us if we thwart His designs; if we, His noblest works on earth, instead of adding to the universal harmony of His creation, make monsters of ourselves, moral blots upon the beautiful face of His world? It were idle for Him to give us the knowledge of His will and then to stand by and let us disfigure His fairest designs; to bid us do what is right, and then let us do wrong without exacting redress or atonement. If He is wise, He must not only lay down the law, but He must also enforce it; He must make it our highest interest to keep His law, to do the right; so that ultimately those men shall be happy who have done it, and those who have thwarted His designs shall be compelled to rue it. He will not deprive us of liberty, the fairest gift to an intelligent creature, but He will hold out rewards and punishments to induce us to keep the law and to avoid its violation. Once He has promised and threatened, His justice and His holiness compel Him to fulfil His threats and promises. A man can commit no rasher act than to ignore, defy, and violate that higher law of which we are speaking, and which, if it must direct all men, especially requires the respect and obedience of those into whose hands he has placed at times the lives of their fellow-men, the greatest of earthly treasures.

I have insisted so much, gentlemen, on the existence of the higher law, on its binding power and on the necessity of observing it, because it is the foundation of my whole course of lectures. If there were no higher law, then there would be no Medical Jurisprudence, in the true sense of the word. For Jurisprudence studies the principles that underlie legal enactments, and if there were no higher law, there would be no such principles; then the knowledge of the human law would fill the whole programme. This in fact is the contention of the defendant of craniotomy to whom I have referred; and he boldly applies his speculation to a matter in which the physician has the most frequent opportunity to exhibit his fidelity to principle, or his subserviency to the requirements of temporary expediency at the sacrifice of duty.

8. You will find, gentlemen, as we proceed in our course, that Doctors have very many occasions in which to apply the lessons of Jurisprudence in their medical practice. I even suspect that they need to be more conscientious in regard to the dictates of the higher law than any other class of men, the clergy alone, perhaps, excepted. They need this not only for their own good, but also for the good of their patients and of the community at large. The reasons are these:

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.

The effect thus produced upon many minds is to shake their convictions, to say the least; and I need not tell you, gentlemen, that weak convictions are not likely to be proof against violent and repeated temptations. In fact, if a physician, misled by any of those many theories which are often inculcated or at least insinuated by false scientists, can ever convince himself, or even can begin to surmise that, after all, there may be no such thing as a higher law before which he is responsible for even his secret conduct, then what is to prevent him from becoming a dangerous person to the community? If he see much temporal gain on the one hand, and security from legal prosecution on the other, what would keep him in the path of duty and honesty? Especially if he can once make himself believe that, for all he knows, he may be nothing more than a rather curiously developed lump of matter, which is to lose forever all consciousness in death. Why should he not get rid of any other evolved lump of matter if it stand in the way of his present or prospective happiness? Those are dangerous men who inculcate such theories; it were a sad day for the medical profession and for the world at large if ever they found much countenance among physicians. Society cannot do without the higher law; this law is to be studied in Medical Jurisprudence.

It is my direct object, gentlemen, to explain this law to you in its most important bearings, and thus to lay before you the chief duties of your profession. The principal reason why I have undertaken to deliver this course of lectures—the chief reason, in fact, why the Creighton University has assumed the management of this Medical College—is that we wish to provide for the West, as far as we are able, a goodly supply of conscientious physicians, who shall be as faithful and reliable as they will be able and well informed; whose solid principles and sterling integrity shall be guarantees of upright and virtuous conduct.

That this task of mine may be successfully accomplished, I will endeavor to answer all difficulties and objections that you may propose. I will never consider it a want of respect to me as your professor if you will urge your questions till I have answered them to your full satisfaction. On the contrary, I request you to be very inquisitive; and I will be best pleased with those who show themselves the most ready to point out those difficulties, connected with my lectures, which seem to require further answers and explanations.
