According to his thinking, man was not born for a particular purpose. Quite the opposite: a purpose developed only with the birth of an individual. To objectively fabricate a purpose at the outset and to apply it to a human being was to rob him at birth of freedom of action. Hence, purpose was something that the individual had to make for himself. But no one, no matter who, could freely create a purpose. This was because the purpose of one's existence was as good as announced to the universe by the course of that existence itself. Starting from this premise, Daisuke held that one's natural activities constituted one's natural purposes. A man walked because he wanted to. Then walking became his purpose. He thought because he wanted to. Then, thinking became his purpose. Just as to walk or to think for a particular purpose meant the degradation of walking and thinking, so to establish an external purpose and to act to fulfill it meant the degradation of action. Accordingly, those who used the sum of their actions as a means to an end were in effect destroying the purpose of their own existence.

All you do is think. Because all you do is think, you've constructed two separate worlds—one inside your head and one outside. Just the fact that you tolerate this enormous dissonance—why, that's a great intangible failure already.

Anyone who sang the praises of undying love in this day and age belonged to the first rank of hypocrites in Daisuke's estimate.

As I see it, you’re always unsteady on your legs. You can’t find your courage. You’ll go to any length to avoid what displeases you, and you gallop after whatever you want. And why is that? There is no why; it’s because you’re free to. You enjoy the luxury of picking and choosing because you have the latitude. You’re never pushed into a tight corner as I am, so it never occurs to you to thumb your nose at the world.

But do you imagine there’s a certain type of person in the world who conforms to the idea of a ‘bad person'? You’ll never find someone who fits that mold neatly, you know. On the whole, all people are good, or at least they’re normal. The frightening thing is that they can suddenly turn bad when it comes to the crunch. That’s why you have to be careful.

But facts, remembered or not, are all, alas, still facts

But once I could look back on it in a calmer frame of mind, it struck me that his motive was surely not so simple and straightforward. Had it resulted from a fatal collision between reality and ideals? Perhaps—but this was still not quite it. Eventually, I began to wonder whether it was not the same unbearable loneliness that I now felt that had brought K to his decision.

Daisuke was of course equipped with conversation that, even if they went further, would allow him to retreat as if nothing had happened. He had always wondered at the conversations recorded in Western novels, for to him, they were too bald, too self-indulgent, and moreover, too unsubtly rich. However, they read in the original, he thought they reflected a taste that could not be translated into Japanese. Therefore, he had not the slightest intention of using imported phrases to develop his relationship with Michael. Between the two of them at least, ordinary words sufficed perfectly well. But the danger was of slipping from point A to point B without realizing it. Daisuke managed to stand his ground only by a hair's breadth. When he left, Michael saw him to the entranceway and said, "Do come again, please? It's so lonely.

Daisuke was the sort of man who, once he was disturbed by something, no matter what, could not let go of it until he had pursued it to the utmost. Moreover, having the capacity to assess the folly of any given obsession, he was forced to be doubly conscious of it. Three of four years ago he had tackled the question of the process whereby his waking mind entered the realm of dreams. At night, when he had gotten under the covers and begun to doze off nicely, he would immediately think, this is it, this is how I fall asleep. No sooner had he thought of this than he was wide awake. When he had managed to doze off again, he would immediately think, here it is. Night after night, he was plagued by his curiosity and would repeat the same procedure two or three times. In the end, he became disgusted in spite of himself. He wanted somehow to escape his agony. Moreover, he was thoroughly impressed by the extent of his folly. To appeal to his conscious mind in order to apprehend his unconscious, and to try to recollect both at the same time was, as James had put it, analogous to lighting a candle to examine the dark, or stopping a top in order to study is movements; at that rate, it stood to reason that he would never again be able to sleep. He knew all this, but when night came, he still thought, now...
