More than any other, perhaps, he approached, by his intimate affinity, Des Esseintes’ meditative cast of mind.
If Baudelaire, in the hieroglyphics of the soul, had deciphered the return of the age of sentiment and ideas, Poe, in the field of morbid psychology had more especially investigated the domain of the soul.
Under the emblematic title, The Demon of Perversity, he had been the first in literature to pry into the irresistible, unconscious impulses of the will which mental pathology now explains more scientifically. He had also been the first to divulge, if not to signal the impressive influence of fear which acts on the will like an anaesthetic, paralyzing sensibility and like the curare, stupefying the nerves. It was on the problem of the lethargy of the will, that Poe had centered his studies, analyzing the effects of this moral poison, indicating the symptoms of its progress, the troubles commencing with anxiety, continuing through anguish, ending finally in the terror which deadens the will without intelligence succumbing, though sorely disturbed. Death, which the dramatists had so much abused, he had in some manner changed and made more poignant, by introducing an algebraic and superhuman element; but in truth, it was less the real agony of the dying person which he described and more the moral agony of the survivor, haunted at the death bed by monstrous hallucinations engendered by grief and fatigue. With a frightful fascination, he dwelt on acts of terror, on the snapping of the will, coldly reasoning about them, little by little making the reader gasp, suffocated and panting before these feverish mechanically contrived nightmares.
Convulsed by hereditary neurosis, maddened by a moral St. Vitus dance, Poe’s creatures lived only through their nerves; his women, the Morellas and Ligeias, possessed an immense erudition. They were steeped in the mists of German philosophy and the cabalistic mysteries of the old Orient; and all had the boyish and inert breasts of angels, all were sexless.
