"No, what worries me is that I might in a sense adapt to this environment and come to be comfortable here and not resent it anymore. And I am afraid that as the years go by that I may forget, I may begin to lose my memories of the mountains and the woods and that's what really worries me, that I might lose those memories, and lose that sense of contact with wild nature in general.

“An antitechnological movement that focused on the elimination of capitalism would gain little in return for an enormous expenditure of energy. What is worse, by focusing on capitalism the movement would distract its own and other people's attention from the far more important objective of bringing down the technological system itself.”

Apart from the most elementary mathematics, like arithmetic or high school algebra, the symbols, formulas and words of mathematics have no meaning at all.

But the facts are so incredible that no one takes them seriously. So the secret is in no danger.”
