“The most erroneous stories are those we think we know best - and therefore never scrutinize or question.”

“We are the offspring of history, and must establish our own paths in this most diverse and interesting of conceivable universes—one indifferent to our suffering, and therefore offering us maximum freedom to thrive, or to fail, in our own chosen way.”

“If we use the past only to creature heroes for present purposes, we will never understand the richness of human thought or the plurality of ways of knowing.”

“The facts of nature are what they are, but we can only view them through the spectacles of our mind. Our mind works largely by metaphor and comparison, not always (or often) by relentless logic. When we are caught in conceptual traps, the best exit is often a change in metaphor — not because the new guideline will be truer to nature (for neither the old nor the new metaphor lies “out there” in the woods), but because we need a shift to more fruitful perspectives, and metaphor is often the best agent of conceptual transition.”

“I had learned that a dexterous, opposable thumb stood among the hallmarks of human success. We had maintained, even exaggerated, this important flexibility of our primate forebears, while most mammals had sacrificed it in specializing their digits. Carnivores run, stab, and scratch. My cat may manipulate me psychologically, but he'll never type or play the piano.”

“In Darwins post-platonische werelds is de variatie de fundamentele werkelijkheid en veranderen berekende gemiddelden in abstracties. We blijven echter de voorkeur geven aan het oudere en tegengestelde standpunt: we zien variatie nog steeds als een massa onlogische toevalligheden, die hoofdzakelijk van waarde is omdat zo'n spreiding te gebruiken is voor de berekening van een gemiddelde, hetgeen we dan beschouwen als iets wat een essentie nog het best benadert.”

“We have become, by the power of a glorious evolutionary accident called intelligence, the stewards of life's continuity on earth. We did not ask for this role, but we cannot abjure it. We may not be suited to it, but here we are.”
