It is impossible to effect this suddenly, or by reasoning, for madmen can never be convinced of the folly of their opinions. Their belief in them is firmly fixed, and cannot be shaken. The more frequently these opinions are recurred to under a conviction of their truth, the deeper they subside in the mind and become more obstinately entangled: the object should therefore be to prevent such recurrence by occupying the mind on different subjects, and thus diverting it from the favorite and accustomed train of ideas. As I have been induced to suppose, from the appearances on dissection, that the immediate cause of this disease probably consists in a morbid affection of the brain, all modes of cure by reasoning, or conducting the current of thought into different channels, must be ineffectual, so long as such local disease shall continue. It is, however, likely that insanity is often continued by habit; that incoherent associations, frequently recurred to, become received as truths, in the same manner as a tale, which, although untrue, by being repeatedly told, shall be credited at last by the narrator, as if it had certainly happened. It should likewise be observed, that these incorrect associations of ideas are acquired in the same way as just ones are formed, and that such are as likely to remain, as the most accurate opinions. The generality of minds are very little capable of tracing the origin of their ideas; there are many opinions we are in possession of, with the history and acquisition of which, we are totally unacquainted. We see this in a remarkable manner in patients who are recovering: they will often say such appearances have been presented to my mind with all the force and reality of truth: I saw them as plainly as I now behold any other object, and can hardly be persuaded that they did not occur. It also does not unfrequently happen, that patients will declare, that certain notions are forced into their minds, of which they see the folly and incongruity, and complain that they cannot prevent their intrusion. It is of great service to establish a system of regularity in the actions of insane people. They should be made to rise, take exercise, and food, at stated times. Independently of such regularity contributing to health, it also renders them much more easily manageable. As the patient should be taught to view the superintendant as a superior person, the latter should be particularly cautious never to deceive him. Madmen are generally more hurt at deception than punishment; and whenever they detect the imposition, never fail to lose that confidence and respect, which they ought to entertain for the person who governs them.
