Impacts Quotes (page 4)
Orwell was dealing with communism and his disillusionment with communism in Russia and what he saw the communists do in Spain. His novel was a response to those political situations. Whereas I was interested in more things than the political atmosphere. I was considering the whole social atmosphere: the impact of TV and radio and the lack of education. I could see the coming event of schoolteachers not teaching reading anymore. The less they taught, the more you wouldn't need books.
Ray Bradbury
Since, in the long run, every planetary civilization will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring--not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive... If our long-term survival is at stake, we have a basic responsibility to our species to venture to other worlds.
Carl Sagan
Of course, I am interested, but I would not dare to talk about them. In talking about the impact of ideas in one field on ideas in another field, one is always apt to make a fool of oneself. In these days of specialization there are too few people who have such a deep understanding of two departments of our knowledge that they do not make fools of themselves in one or the other.
Richard P. Feynman
