The will being a spiritual power can no more be diseased than can the intellect. But as the imagination, an organic power, can be disorganized by an affection of the brain, and by delusion deceive the intellect, thus producing mental insanity, similarly I fully admit that a man's passions, which are also organic powers, common to us and to brute animals, can become disordered by bodily disease; and the passions, when excited, will strive to drag along the consent of the will, as we all experience. A man whose passions are abnormally influenced by bodily disease, so that he is constantly inclined to act very unreasonably, may well be called morally insane. Such a state of insanity is not a rare occurrence, and there is no objection to denominate it emotional, affective, or moral insanity. But in such a disease the will remains free; if a man does what he knows to be wrong and criminal, he then sees reasons for not doing it; and in this lies the root of his liberty. For seeing himself drawn in one direction by one motive and in another by another motive, he is not determined in his choice but by the act of his free will. A merely organic faculty must be determined by the stronger attraction, as is the case with brutes; but a spiritual faculty, as our will is, acts freely in choosing between two opposing motives of action. This is the philosophical or psychological explanation: and I am well pleased to find that here again, as in the matter of mental insanity, the courts of England and the leading courts of the United States follow the sound teachings of philosophy. The nearest advance I know of, that has been made towards the recognition of this moral insanity as a total bar to responsibility, was made in 1864 by the court of appeals in Kentucky, and again in 1869 under the same presiding Judge Robertson. But Chief Justice Williams rebukes this strange ruling in most emphatic language. He says: "In all the vague, uncertain, intangible, and undefined theories of the most impractical metaphysician in psychology or moral insanity, no court of last resort in England or America, so far as has been brought to our knowledge, ever before announced such a startling, irresponsible, and dangerous proposition of law, as that laid down in the inferior court. For, if this be law, then no longer is there any responsibility for homicide, unless it be perpetrated in calm, cool, considerate condition of mind.
