When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
The greatest tragedy in mankind's entire history may be the hijacking of morality by religion.
There is hopeful symbolism in the fact that flags do not wave in a vacuum.
Every revolutionary idea seems to evoke three stages of reaction. They may be summed up by the phrases: 1- It's completely impossible. 2- It's possible, but it's not worth doing. 3- I said it was a good idea all along.
