Eva Martin's Translation
This must be thought out; it was clear that there had been no hallucination at the station then, either; something had actually happened to him, on both occasions; there was no doubt of it. But again a loathing for all mental exertion overmastered him; he would not think it out now, he would put it off and think of something else. He remembered that during his epileptic fits, or rather immediately preceding them, he had always experienced a moment or two when his whole heart, and mind, and body seemed to wake up to vigour and light; when he became filled with joy and hope, and all his anxieties seemed to be swept away for ever; these moments were but presentiments, as it were, of the one final second (it was never more than a second) in which the fit came upon him. That second, of course, was inexpressible. When his attack was over, and the prince reflected on his symptoms, he used to say to himself: "These moments, short as they are, when I feel such extreme consciousness of myself, and consequently more of life than at other times, are due only to the disease—to the sudden rupture of normal conditions. Therefore they are not really a higher kind of life, but a lower." This reasoning, however, seemed to end in a paradox, and lead to the further consideration:—"What matter though it be only disease, an abnormal tension of the brain, if when I recall and analyze the moment, it seems to have been one of harmony and beauty in the highest degree—an instant of deepest sensation, overflowing with unbounded joy and rapture, ecstatic devotion, and completest life?" Vague though this sounds, it was perfectly comprehensible to Muishkin, though he knew that it was but a feeble expression of his sensations.
That there was, indeed, beauty and harmony in those abnormal moments, that they really contained the highest synthesis of life, he could not doubt, nor even admit the possibility of doubt. He felt that they were not analogous to the fantastic and unreal dreams due to intoxication by hashish, opium or wine. Of that he could judge, when the attack was over. These instants were characterized—to define it in a word—by an intense quickening of the sense of personality. Since, in the last conscious moment preceding the attack, he could say to himself, with full understanding of his words: "I would give my whole life for this one instant," then doubtless to him it really was worth a lifetime. For the rest, he thought the dialectical part of his argument of little worth; he saw only too clearly that the result of these ecstatic moments was stupefaction, mental darkness, idiocy. No argument was possible on that point. His conclusion, his estimate of the "moment," doubtless contained some error, yet the reality of the sensation troubled him. What's more unanswerable than a fact? And this fact had occurred. The prince had confessed unreservedly to himself that the feeling of intense beatitude in that crowded moment made the moment worth a lifetime. "I feel then," he said one day to Rogojin in Moscow, "I feel then as if I understood those amazing words—'There shall be no more time.'" And he added with a smile: "No doubt the epileptic Mahomet refers to that same moment when he says that he visited all the dwellings of Allah, in less time than was needed to empty his pitcher of water." Yes, he had often met Rogojin in Moscow, and many were the subjects they discussed. "He told me I had been a brother to him," thought the prince. "He said so today, for the first time."
Constance Garnett's Translation
[...] It was clear now that it had not been his imagination at the station either, that something real must have happened to him, and that it must be overcome again by a sort of insuperable inner loathing: he did not want to think anything out, and he did not; he fell to musing on something quite different.
He remembered among other things that he always had one minute just before the epileptic fit (if it came on while he was awake), when suddenly in the midst of sadness, spiritual darkness and oppression, there seemed at moments a flash of light in his brain, and with extraordinary impetus all his vital forces suddenly began working at their highest tension. The sense of life, the consciousness of self, were multiplied ten times at these moments which passed like a flash of lightning. His mind and his heart were flooded with extraordinary light; all his uneasiness, all his doubts, all his anxieties were relieved at once; they were all merged in a lofty calm, full of serene, harmonious joy and hope. But these moments, these flashes, were only the prelude of that final second (it was never more than a second) with which the fit began. That second was, of course, unendurable. Thinking of that moment later, when he was all right again, he often said himself that all these gleams and flashes of the highest sensation of life and self-consciousness, and therefore also of the highest form of existence, were nothing but disease, the interruption of the normal conditions; and if so, uit was not at all the highest form of being, but on the contrary must be counted the lowest. And yet he came at last to an extremely paradoical conclusion. "What if it is disease?" he decided at last. "what does it matter that it is an abnormal intensity, if the result, if the minute of sensation, remembered and analyzed afterwards in health, turns out to be the acme of harmony and beauty, and gives a feeling, unknown and undivined till then, of completeness, of proportion, of reconciliation, and of ecstatic devotional merging in the highest synthesis of life?" These vague expressions seemed to him very comprehensible, though too weak. That it reall was "beauty and worship," that it really was the "highest synthesis of life" he could not doubt, and could not admit the possibility of doubt. It was not as though he saw abnormal and unreal visions of some sort at that moment, as from hashish, opium, or wine, destroying the reason and distorting the soul. He was quite capable of judging of that when the attack was over. These moments were only and extraordinary quickening of self-consciousness--if the condition was to be expressed in one word--and at the same time of the direct sensation of existence in the most intense degree. Since at that second, that is at the very last conscious moment before the fit, he had time to say to himself clearly and consciously, "Yes, for this moment one might give one's whole life!" then without doubt that moment was really worth the whole of life. He did not insist on the dialectical part of his argument, however. Stupefaction, spiritual darkness, idiocy, stood before him conspicuously as the consequence of these "higher moments"; seriously, of course, he could not have disputed it. There was undoubtedly a mistake in his conclusion--that is, in his estimate of that minute, but the reality of the sensation somewhat perplexed him. What was he to make of that reality? For the very thing had happened; he actually had said to himself at that second that, for the infinite happiness he had felt in it, that second really might well be worth the whole of life. "At that moment," Rogozhin one day in Moscow at the time when they used to meet there, "at that moment I seem somehow to understand the extraordinary saying that there shall be no more time. Probably," he added, smiling, "this is the very second which was not long enough for the water to be spilt out of Muhammad's pitcher, though the epileptic prophet had time to gaze at all the habitations of Allah."
