Monomania

Definition and stakes

Portrait of Eugène Sue Eugène Sue,  Arthur

“ But when it is a question of monomania (and I think that my intense distrust amounted to monomania) , wise and sensible ideas are the last that ever come into our minds.
It was all in vain, then, that I had laughed at those wicked stories that had been constructed from the most ordinary occurrences. Without for a moment reflecting on my inconsequence, I was about to do what was a thousand times worse than forge a slander. I was about to calumniate that sacred thing, grief; to profit by what I had accidentally discovered.

Portrait of Eugène Sue Eugène Sue,  Arthur

“ I dwelt with a sort of cruel enjoyment on all I had so unworthily sacrificed, not to distrust, but to a species of monomania as wicked as it was stupid; to be sure, it had brought terrible suffering on me, but what of that? A crazy man suffers, too; but is the harm he does any the less harmful?
What more can I say? The vision of that seductive woman appeared more beautiful, more voluptuous, than ever before. The saddening vulgarity of the saying that we only know the worth of happiness when we have lost it, was the dolorous theme upon which my despair played every sort of variation.

William D. Granger,  How to Care for the Insane: A Manual for Nurses

“ Monomania.—This is a term belonging to common speech, but there is not an agreement of opinion as to the existence of such a special form of insanity, nor among those who believe in it, as to what it is and what are its symptoms.
Monomania really means an insanity with but one, or, at most, a small class of delusions of the same character, the rest of the mind showing no disease. Hardly any one believes in the existence of such a narrow limit to insanity, and, getting beyond this point, there is no agreement where the limit should be set up to mark and bound it.
