I certainly should think that I was mad, absolutely mad, if I were not conscious that I knew my state, if I could not fathom it and analyze it with the most complete lucidity. I should, in fact, be a reasonable man laboring under a hallucination. Some unknown disturbance must have been excited in my brain, one of those disturbances which physiologists of the present day try to note and to fix precisely, and that disturbance must have caused a profound gulf in my mind and in the order and logic of my ideas. Similar phenomena occur in dreams, and lead us through the most unlikely phantasmagoria, without causing us any surprise, because our verifying apparatus and our sense of control have gone to sleep, while our imaginative faculty wakes and works. Was it not possible that one of the imperceptible keys of the cerebral finger-board had been paralyzed in me? Some men lose the recollection of proper names, or of verbs, or of numbers, or merely of dates, in consequence of an accident. The localization of all the avenues of thought has been accomplished nowadays; what, then, would there be surprising in the fact that my faculty of controlling the unreality of certain hallucinations should be destroyed for the time being? I thought of all this as I walked by the side of the water. The sun was shining brightly on the river and made earth delightful, while it filled me with love for life, for the swallows, whose swift agility is always delightful in my eyes, for the plants by the riverside, whose rustling is a pleasure to my ears. By degrees, however, an inexplicable feeling of discomfort seized me. It seemed to me as if some unknown force were numbing and stopping me, were preventing me from going further and were calling me back. I felt that painful wish to return which comes on you when you have left a beloved invalid at home, and are seized by a presentiment that he is worse. I, therefore, returned despite of myself, feeling certain that I should find some bad news awaiting me, a letter or a telegram. There was nothing, however, and I was surprised and uneasy, more so than if I had had another fantastic vision. August 8. I spent a terrible evening, yesterday. He does not show himself any more, but I feel that He is near me, watching me, looking at me, penetrating me, dominating me, and more terrible to me when He hides himself thus than if He were to manifest his constant and invisible presence by supernatural phenomena. However, I slept. August 9. Nothing, but I am afraid. August 10. Nothing; but what will happen to-morrow? August 11. Still nothing. I cannot stop at home with this fear hanging over me and these thoughts in my mind; I shall go away. August 12. Ten o'clock at night. All day long I have been trying to get away, and have not been able. I contemplated a simple and easy act of liberty, a carriage ride to Rouen--and I have not been able to do it. What is the reason?
