"Perversity, she thought. Could that have been what happened to the human race — a willing perversity that set at naught all human values which had been so hardly won and structured in the light of reason for a span of more than a million years? Could the human race, quite out of hand and with no sufficient reason, have turned its back upon everything that had built humanity? Or was it, perhaps, no more than second childhood, a shifting of the burden off one's shoulders and going back to the selfishness of the child who romped and frolicked without thought of consequence or liability?"

“To cover up actual lack of knowledge, the tale develops an explanation which amounts to divine intervention. It is an easy and, to the primitive mind, a plausible and satisfactory way to explain something of which nothing at all is known.”

“The party was beginning to get noisy—not boisterous, but noisy. It was beginning to acquire that stale air of futility to which, in the end, all parties must fall victim.”

“Without consciousness and intelligence, the universe would lack meaning.”

“My reluctance to use alien invasion is due to the feeling that we are not likely to be invaded and taken over. It would seem to me that by the time a race has achieved deep space capability it would have matured to a point where it would have no thought of dominating another intelligent species. Further than this, there should be no economic necessity of its doing so. By the time it was able to go into deep space, it must have arrived at an energy source which would not be based on planetary natural resources.”

“It was not his fight. Not personally his fight. No more his fight than any one of them. But he had made it his. Because of Stone, because of Rand and Harriet, because of priest who’d hounded him across half the continent, he had tried to make a fight of it. And perhaps, as well, because of something undefinable, unknown to himself, unsuspected in himself—some crazy idealism, some deep-rooted sense of justice, some basic aversion to bullies and bigots and reformers.”

“It would be three-dimensional chess with a million billion squares and a million pieces, and with the rules changing ever move.”
