Book 1
6
THE modes of mania are infinite in species, but one alone in genus. For it is altogether a chronic derangement of the mind, without fever. For if fever at any time should come on, it would not owe its peculiarity to the mania, but to some other incident. Thus wine inflames to delirium in drunkenness; and certain edibles, such as mandragora and hyoscyamus, induce madness: but these affections are never called mania; for, springing from a temporary cause, they quickly subside, but madness has something confirmed in it. To this mania there is no resemblance in the dotage which is the calamity of old age, for it is a torpor of the senses, and a stupefaction of the gnostic and intellectual faculties by coldness of the system. But mania is something hot and dry in cause, and tumultuous in its acts. And, indeed, dotage commencing with old age never intermits, but accompanies the patient until death; while mania intermits, and with care ceases altogether. And there may be an imperfect intermission, if it take place in mania when the evil is not thoroughly cured by medicine, or is connected with the temperature of the season. For in certain persons who seemed to be freed from the complaint, either the season of spring, or some error in diet, or some incidental heat of passion, has brought on a relapse.
