I only hope that when I am free, as they are free to go in quest, of the knowledge beyond the bounds of life, it may not seem better to me to rest.

In the course of my life, I have often had to eat my words, and I must confess that I have always found it a wholesome diet.

The most important knowledge is that which guides the way you lead your life.

The only absolute knowledge attainable by man is that life is meaningless.

Life consists in penetrating the unknown, and fashioning our actions in accord with the new knowledge thus acquired.

It is never my custom to use words lightly. If twenty-seven years in prison have done anything to us, it was to use the silence of solitude to make us understand how precious words are and how real speech is in its impact on the way people live and die.
