“If civilization is to survive, it must live on the interest, not the capital, of nature.”

“Societies that do not eat people are fascinated by those that do.”

“Even today, some opt for the comforts of mystification, preferring to believe that the wonders of the ancient world were built by Atlanteans, gods, or space travelers, instead of by thousands toiling in the sun. Such thinking robs our forerunners of their due, and us of their experience. Because then one can believe whatever one likes about the past - without having to confront the bones, potsherds, and inscriptions which tell us that people all over the world, time and again, have made similar advances and mistakes.”

“If civilization is to survive, it must live on the interest, not the capital, of nature.”

“Though we became experimental creatures of our own devising, it’s important to bear in mind that we had no inkling of this process, let alone its consequences, until only the last six or seven of our 100,000 generations. We have done it all sleepwalking. Nature let a few apes into the lab of evolution, switched on the lights, and left us there to mess about with an ever-growing supply of ingredients and processes. The effect on us and the world has accumulated ever since. Let’s list a few steps between the earliest times and this: sharp stones, animal skins, useful bits of bone and wood, wild fire, tame fire, seeds for eating, seeds for planting, houses, villages, pottery, cities, metals, wheels, explosives. What strikes one most forcefully is the acceleration, the runaway progression of change - or to put it another way, the collapsing of time. From the first chipped stone to the first smelted iron took nearly 3 million years; from the first iron to the hydrogen bomb took only 3,000.”

“People afraid of outsiders are easily manipulated. The warrior caste, supposedly society's protectors, often become protection racketeers. In times of war or crisis, power is easily stolen from the many by the few on a promise of security. The more elusive or imaginary the foe, the better for manufacturing consent. The Inquisition did a roaring trade against the Devil.”
