“And so Discovery drove on toward Saturn, as often as not pulsating with the cool music of the harpsichord, the frozen thoughts of a brain that had been dust for twice a hundred years.”

“Bowman was aware of some changes in his behavior patterns; it would have been absurd to expect anything else in the circumstances. He could no longer tolerate silence; except when he was sleeping, or talking over the circuit to Earth, he kept the ship's sound system running at almost painful loudness. / At first, needing the companionship of the human voice, he had listened to classical plays--especially the works of Shaw, Ibsen, and Shakespeare--or poetry readings from Discovery's enormous library of recorded sounds. The problems they dealt with, however, seemed so remote, or so easily resolved with a little common sense, that after a while he lost patience with them. / So he switched to opera--usually in Italian or German, so that he was not distracted even by the minimal intellectual content that most operas contained. This phase lasted for two weeks before he realized that the sound of all these superbly trained voices was only exacerbating his loneliness. But what finally ended this cycle was Verdi's Requiem Mass, which he had never heard performed on Earth. The "Dies Irae," roaring with ominous appropriateness through the empty ship, left him completely shattered; and when the trumpets of Doomsday echoed from the heavens, he could endure no more. / Thereafter, he played only instrumental music. He started with the romantic composers, but shed them one by one as their emotional outpourings became too oppressive. Sibelius, Tchaikovsky, Berlioz, lasted a few weeks, Beethoven rather longer. He finally found peace, as so many others had done, in the abstract architecture of Bach, occasionally ornamented with Mozart. / And so Discovery drove on toward Saturn, as often as not pulsating with the cool music of the harpsichord, the frozen thoughts of a brain that had been dust for twice a hundred years.”

“At the present rate of progress, it is almost impossible to imagine any technical feat that cannot be achieved - if it can be achieved at all - within the next few hundred years.”

“What was more, they had taken the first step toward genuine friendship. They had exchanged vulnerabilities.”

“If such a thing had happened once, it must surely have happened many times in this galaxy of a hundred billion suns.”

“But it had been widely argued that advanced intelligence could never arise in the sea; there were not enough challenges in so benign and unvarying an environment.”

“So this, thought Jan, with a resignation that lay beyond all sadness, was the end of man. It was an end that no prophet had foreseen – an end that repudiated optimism and pessimism alike.Yet it was fitting: it had the sublime inevitability of a great work of art. Jan had glimpsed the universe in all its immensity, and knew now that it was no place for man. He realized at last how vain, in the ultimate analysis, had been the dream that lured him to the stars.For the road to the stars was a road that forked in two directions, and neither led to a goal that took any account of human hopes or fears.”
