"I would strongly press upon you this view of the subject, — one to which I have already referred, that this is, in fact, the stand- point from which we all instinctively view a case of Insanity, when called upon as practical men to form a diagnosis, or offer a prognosis, upon any case submitted to us for the first time. We ask ourselves, is this a case of congenital moral perversion or intellectual deficiency? Is it one connected with masturbation, with pubescence, with hysteria, with phthisis, with drinking, with uterine disease, with brain disease, and so forth ? If this is true, surely this is at least the practical basis upon which to form a Classification of the Insane; and if not the most scientific, it is certainly more so than the present poor, uncertain, and conventional one, or perhaps than any one which can be founded upon a physiological or psychological basis, in our present very imperfect knowledge of the physiology of the Brain. It has this especial merit, at least — that it ever keeps before us the all-important principle, that Insanity is a disease of the body, whether it be of some remote organ sympathetically acting on the mind, or of the material organ of the mind itself."
