Never forget that when we are silent, we are one. And when we speak, we are two.

You cannot shake hands with a clenched fist.

The power to question is the basis of all human progress.

My grandfather once told me that there are two kinds of people: those who do the work and those who take the credit. He told me to try to be in the first group; there was less competition there.

Without courage, you cannot practice any other virtue. You have to have courage-courage of different kinds: first, intellectual courage, to sort out different values and make up your mind about which is the one which is right for you to follow. You have to have moral courage to stick up to that-no matter what comes in your way, no matter what the obstacle and the opposition is. Opposition comes not only from your enemies but sometimes from your friends, and the latter is much more difficult to face. You have to have physical courage, because very often going along the path of your choice is full of physical hardship.

Defeats are always pitiful. Victories are always last resources.
