It must be remembered too that madness itself has a thousand forms, numberless causes, and even some distinct names. Delusion, infatuation, frenzy, lunacy--these are not the same; they all express different degrees of the affection. Again, the causes are not only different in men and women, but, in men, they are different for the old and for the young; for instance, in young men some redundant humour is the usual cause; whereas with the old a shrewdly timed slander, or very likely a fancied domestic slight, will get hold of them, first cloud their understanding, and finally drive them distracted. As for women, all sorts of things effect a lodgement and make easy prey of them, especially bitter dislike, envy of a prosperous rival, pain or anger. These feelings smoulder on, gaining strength with time, till at last they burst out in madness. Such, sir, has been your wife's case, perhaps with the addition of some recent trouble; for she used to have no strong dislikes, yet she is now in the grasp of the malady--and that beyond hope of medical relief. For if any physician undertakes and cures the case, you have my permission to hate me for the wrong I have done you. Yet I must go so far as to say that, even had the case not been so desperate--had there been a glimmer of hope--even then I should not have lightly intervened, nor been very ready to administer drugs; I should have been afraid of what might happen, and of the sort of stories that might get about. You know the universal belief that every step-mother, whatever her general merits, hates her step-sons; it is supposed to be a feminine mania from which none of them is exempt. If the disease had taken a wrong turn, and the medicine failed of its effect, there would very likely have been suspicions of intentional malpractice.
