The supreme guide in life is knowledge.

In human life, you will find players of religion until the knowledge and proficiency in religion will be cleansed from all superstitions, and will be purified and perfected by the enlightenment of real science.

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

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.

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.
