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.

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.

For if we allow that human life is always guided by reason, we destroy the premise that life is possible at all.

Progress consists only in the greater clarification of answers to the basic questions of life.

To know God and to live is the same thing. God is Life.
