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:
