“You know, in principle, why our world is as it is. Isn’t that sufficient? Is it really necessary for you to understand every detail?”
But if I don’t understand, Morrow thought sourly, then you can control me. Arbitrarily. And that’s what I find hard to accept.

To some extent the human race today seems to react as a single organism to great events. After all, we live in a wired world. Memes—information, ideas, fears, and hopes—spread around the media and online information channels literally at light speed.

It (i. e., agriculture) was the most profound revolution in hominid living since Homo erectus had left the forest and committed themselves to the savannah. Compared to this phase shift, the advances of the future—even genetic engineering—were details. There would never be so significant a change again, not until humans themselves disappeared from the planet.

One might imagine that, in any conflict between rational humans and religious humans, the rational ought to win. After all, it is rationality that invented gunpowder!

The sign of a strong, independent mind.”

His overriding lesson for thinkers like Hutton was that scientists, even those occupied by an apparently ‘concrete’ discipline like geology, need to be careful not just about what they claim to know but also about how they claim to know it. Human reason is a fragile thing and prone to be overthrown by suggestibility.

The hugeness of time, and the littleness of man and his achievements, quite crushed me; and my own, petty concerns seemed of absurd insignificance. The story of Humanity seemed trivial, a flash-lamp moment lost in the dark, mindless halls of Eternity.
