“The world changes materially. Science makes advances in technology and understanding. But the world of humanity doesn't change.”

“Science is the only news. When you scan a news portal or magazine, all the human interest stuff is the same old he-said-she-said, the politics and economics the same cyclical dramas, the fashions a pathetic illusion of newness; even the technology is predictable if you know the science behind it. Human nature doesn't change much; science does, and the change accrues, altering the world irreversibly”

“Those societies in which seriousness, tradition, conformity and adherence to long-established - often god-prescribed - ways of doing things are the strictly enforced rule, have always been the majority across time and throughout the world. Such people are not known for their sense of humour and lightness of touch; they rarely break a smile. To them, change is always suspect and usually damnable, and they hardly ever contribute to human development. By contrast, social, artistic and scientific progress as well as technological advance are most evident where the ruling culture and ideology give men and women permission to play, whether with ideas, beliefs, principles or materials. And where playful science changes people's understanding of the way the physical world works, political change, even revolution, is rarely far behind.”

“Please, no matter how we advance in technology please don't abandon the book-there is nothing in our material world more beautiful than a book.”

“I wanted to change the world, now I hope the world doesn't change me.”

“The world would mold men by changing their environment. Christ changes men, who then change their environment. The world would shape human behavior, but Christ can change human nature.”
