“They didn't understand what they were doing.I'm afraid that will be on the tombstone of the human race.”

“Do you want to understand how to swim, or do you want to jump in and start swimming? Only people who are afraid of the water want to understand it. Other people jump in and get wet.”

“Professor Johnston often said that if you didn't know history, you didn't know anything. You were a leaf that didn't know it was part of a tree.”

“Kids didn't have huge backpacks when I was their age. We didn't have backpacks at all. Now it seemed all the kids had them. You saw little second-graders bent over like sherpas, dragging themselves through the school doors under the weight of their packs. Some of the kids had their packs on rollers, hauling them like luggage at the airport. I didn't understand any of this. The world was becoming digital; everything was smaller and lighter. But kids at school lugged more weight than ever.”

“The ultimate lesson is that science isn’t special – at least not anymore. Maybe back when Einstein talked to Niels Bohr, and there were only a few dozen important workers in every field. But there are now three million researchers in America. It’s no longer a calling, it’s a career. Science is as corruptible a human activity as any other. Its practitioners aren’t saints, they’re human beings, and they do what human beings do – lie, cheat, steal from one another, sue, hide data, fake data, overstate their own importance and denigrate opposing views unfairly. That’s human nature. It isn’t going to change”

“The minute we look, we cease being afraid.”

“What makes you think human beings are sentient and aware? There's no evidence for it. Human beings never think for themselves, they find it too uncomfortable. For the most part, members of our species simply repeat what they are told-and become upset if they are exposed to any different view. The characteristic human trait is not awareness but conformity, and the characteristic result is religious warfare. Other animals fight for territory or food; but, uniquely in the animal kingdom, human beings fight for their 'beliefs.' The reason is that beliefs guide behavior which has evolutionary importance among human beings. But at a time when our behavior may well lead us to extinction, I see no reason to assume we have any awareness at all. We are stubborn, self-destructive conformists. Any other view of our species is just a self-congratulatory delusion. Next question.”
