But all evolutionary biologists know that variation itself is natures — Stephen Jay Gould

"[T]rying to keep an intellectual away from literature works about as well as recommending chastity to Homo sapiens, the sexiest primate of all."

"The human mind delights in finding pattern—so much so that we often mistake coincidence or forced analogy for profound meaning. No other habit of thought lies so deeply within the soul of a small creature trying to make sense of a complex world not constructed for it."

"Creative work, in geology and anywhere else, is interaction and synthesis: half-baked ideas from a barroom, rocks in the field, chains of thought from lonely walks, numbers squeezed from rocks in a laboratory, numbers from a calculator riveted to a desk, fancy equipment usually malfunctioning on expensive ships, cheap equipment in the human cranium, arguments before a roadcut."

"Yesterday’s seer is today’s bore."

"Nearly anyone in this line of work would take a bullet for the last pregnant dodo. But should we not admire the person who, when faced with an overwhelmingly sad reality beyond personal blame or control, strives valiantly to rescue whatever can be salvaged, rather than retreating to the nearest corner to weep or assign fault?"

"I’m a profound anti-romantic. Romanticism is dangerous. Romanticism untrammeled by intellect gives rise to fascism after all."

"[explaining to Ernie how April apologized to him] She just showed up at the factory, took off her coat, and begged me to take her. We made love in a way that Ive only ever seen in nature films."

"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."
