“....to abuse the intellect for reasons of pride, vanity, or escape from responsibility, is the fruit of that same tree.”

“There seems to be at least one common denominator to all intelligent life: it was bipedal and bimannual. Four legs was the most practical number for any animal on any planet, and it seems that nature has nothing else to work with. When she decided to give intelligence to a species, she taught him to stand on his hind legs, freeing his forefeet to become tools of his intellect. And she usually taught him by making him use his hands to climb. As a Cophian biologist had said, "Life first tries to climb a tree to get to the stars. When it fails, it comes down and invents the high-C drive.”

“The closer men came to perfecting for themselves a paradise, the more impatient they became with it, and with themselves as well. They made a garden of pleasure, and became progressively more miserable with it as it grew in richness and power and beauty; for then, perhaps, it was easier to see something was missing in the garden, some tree or shrub that would not grow. When the world was in darkness and wretchedness, it could believe in perfection and yearn for it. But when the world became bright with reason and riches, it began to sense the narrowness of the needle's eye, and that rankled for a world no longer willing to believe or yearn.”

“Insofar as thought could be governed at all, it could only be commanded to follow what reason affirmed anyhow; command it otherwise and it would not obey.”

“Men must fumble awhile with error to separate it from truth, I think- as long as they don't seize the error hungrily because it has a pleasanter taste.”

“Sincere--that was the hell of it. From a distance, one's adversaries seemed fiends, but with a closer view, one saw the sincerity and it was as great as one's own. Perhaps Satan was the sincerest of the lot.”
