The pathology of mental disease shows that while, on the one hand, all the faculties, moral and intellectual, may be involved in one common ruin, as in the case of the raving maniac, in other instances one or more only of these faculties may be disordered, leaving the rest undisturbed — that while the mind may be overpowered by delusions which utterly de- moralize it, there often are, on the other hand, delusions which, though the offspring of mental disease, and so far constituting insanity, yet leave the individual in all other respects rational and capable of transacting the ordinary affairs of life.
