He grew paler than before, looking fixedly at her still, as if he were sounding her, to know what there was of her in him. And he contented himself with answering: “You are right, mother. I thank you.” When he was again alone, he dropped into his seat before the table, and tried once more to read his book. But he could not succeed, any more than before, in fixing his attention sufficiently to understand the words, whose letters mingled confusedly together before his eyes. And his mother’s words buzzed in his ears; a vague terror, which had some time before sprung up within him, grew and took shape, haunting him now as an immediate and clearly defined danger. He who two months before had boasted triumphantly of not belonging to the family, was he about to receive the most terrible of contradictions? Ah, this egotistic joy, this intense joy of not belonging to it, was it to give place to the terrible anguish of being struck in his turn? Was he to have the humiliation of seeing the taint revive in him? Was he to be dragged down to the horror of feeling himself in the clutches of the monster of heredity? The sublime idea, the lofty certitude which he had of abolishing suffering, of strengthening man’s will, of making a new and a higher humanity, a healthy humanity, was assuredly only the beginning of the monomania of vanity. And in his bitter complaint of being watched, in his desire to watch the enemies who, he thought, were obstinately bent on his destruction, were easily to be recognized the symptoms of the monomania of suspicion. So then all the diseases of the race were to end in this terrible case—madness within a brief space, then general paralysis, and a dreadful death. From this day forth Pascal was as if possessed. The state of nervous exhaustion into which overwork and anxiety had thrown him left him an unresisting prey to this haunting fear of madness and death. All the morbid sensations which he felt, his excessive fatigue on rising, the buzzing in his ears, the flashes of light before his eyes, even his attacks of indigestion and his paroxysms of tears, were so many infallible symptoms of the near insanity with which he believed himself threatened. He had completely lost, in his own case, the keen power of diagnosis of the observant physician, and if he still continued to reason about it, it was only to confound and pervert symptoms, under the influence of the moral and physical depression into which he had fallen. He was no longer master of himself; he was mad, so to say, to convince himself hour by hour that he must become so. All the days of this pale December were spent by him in going deeper and deeper into his malady. Every morning he tried to escape from the haunting subject, but he invariably ended by shutting himself in the study to take up again, in spite of himself, the tangled skein of the day before.
