Space is big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.
I think that we must find some way to get more common sense, more rationality, in our decisions and less emotion.
Man once surrendering his reason, has no remaining guard against absurdities the most monstrous, and like a ship without rudder, is the sport of every wind.
If one devalues rationality, the world tends to fall apart.
He who opens a school door, closes a prison.
Anything that gives us new knowledge gives us an opportunity to be more rational.
You cannot conquer a free man. The most you can do is kill him.
The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.
The intuitive mind is a sacred gift And the rational mind is a faithful servant.
Study without desire spoils the memory, and it retains nothing that it takes in.
