"A clear prediction in an area undergoing vigorous study permits doctrines to be subject to disproof. The last posture a bureaucratic religion wishes to find itself in is vulnerability to disproof, where an experiment can be performed on which the religion stands or falls."
Natural selection has served as a kind of intellectual sieve, producin — Carl Sagan
"Natural selection has served as a kind of intellectual sieve, producing brains and intelligences increasingly competent to deal with the laws of nature. This resonance, extracted by natural selection, between our brains and the universe may help explain a quandary set by Einstein: The most incomprehensible property of the universe, he said, is that it is so comprehensible."

"There is no question that religions have historically played the role of making people contented with their lot. ...such a doctrine would be very appealing to the ruling classes of a society. ...Many societies, for this reason alone, encourage the contentment with your lot that the religious premise of heaven affords."
"In science it often happens that scientists say, "You know thats a really good argument; my position is mistaken," and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesnt happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion."
"Something dreadful happens to students between first and twelfth grades, and its not just puberty."
"Every kid starts out as a natural-born scientist, and then we beat it out of them. A few trickle through the system with their wonder and enthusiasm for science intact."

"All men suppose what is called Wisdom to deal with the first causes and the principles of things; so that, as has been said before, the man of experience is thought to be wiser than the possessors of any sense-perception whatever, the artist wiser than the men of experience, the masterworker than the mechanic, and the theoretical kinds of knowledge to be more of the nature of Wisdom than the productive."
"The yarns of seamen have a direct simplicity, the whole meaning of which lies within the shell of a cracked nut. But Marlow was not typical (if his propensity to spin yarns be excepted), and to him the meaning of an episode was not inside like a kernel but outside, enveloping the tale which brought it out only as a glow brings out a haze, in the likeness of one of these misty halos that sometimes are made visible by the spectral illumination of moonshine."
"Going up that river was like traveling back to the earliest beginnings of the world, when vegetation rioted on the earth and the big trees were kings. An empty stream, a great silence, an impenetrable forest. The air was warm, thick, heavy, sluggish. There was no joy in the brilliance of sunshine. The long stretches of the waterway ran on, deserted, into the gloom of overshadowed distances."
"The intimate rapport with nature is one of the most precious things in life. Nature is indeed very close to us; sometimes closer than hands and feet, of which in truth she is but the extension. The emotional appeal of nature is tremendous, sometimes almost more than one can bear."
"Are people naturally destructive, immoral, predatory and self-seeking, only to be kept in order by harsh laws and fiercely deterrent mandatory sentences? Or are men and women naturally orderly, merciful, humane and bred with a need for justice and mutual aid? Of course these qualities, or defects, are not evenly distributed, and undoubtedly there is much of each in all of us, but when it comes to the law some sort of distinction can be drawn. Are you a Shylock or a Bassanio? Shylock pinned his faith on the words in the contract, the nature of his bond and the duty of the state to uphold the letter of the law regardless of human suffering. Bassanio put another point of view. More important than the sanctity of the law was the plight of the individual parties in the particular case."
