"There are two kinds of morality—the kind of morality that one imposes on oneself and the kind of morality that one imposes on others. For the first kind of morality, that is, for self-restraint, I have the greatest respect. The second kind of morality I do not respect except when it constitutes self-defense. I have noticed that the people who try hardest to impose moral code on others are often the least careful to abide by that moral code themselves."

“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.”

“Those who are most sensitive about "politically incorrect" terminology are not the average black ghetto-dweller, Asian immigrant, abused woman or disabled person, but a minority of activists, many of whom do not even belong to any "oppressed" group but come from privileged strata of society.”

“The industrial-technological system may survive or it may break down. If it survives, it MAY eventually achieve a low level of physical and psychological suffering, but only after passing through a long and very painful period of adjustment and only at the cost of permanently reducing human beings and many other living organisms to engineered products and mere cogs in the social machine.”

“Consistent failure to attain goals throughout life results in defeatism, low self-esteem or depression.”

“A theme that appears repeatedly in the writings of the social critics of the second half of the 20th century is the sense of purposelessness that afflicts many people in modern society.”

“I must tell you that mathematicians are not scientists, they are artists. ... Apart from the most elementary mathematics, like arithmetic or high school algebra, the symbols, formulas and words of mathematics have no meaning at all. The entire structure of pure mathematics is a monstrous swindle, simply a game, a reckless prank. You may well ask: "Are there no renegades to reveal the truth?" Yes, of course. But the facts are so incredible that no one takes them seriously. So the secret is in no danger.”
