Never once in my life did I ask God for success or wisdom or power or fame. I asked for wonder, and he gave it to me.

Wonder rather than doubt is the root of all knowledge.

A soul can create only when alone.

It is dangerous to take human freedom for granted, to regard it as a prerogative rather than as an obligation, as an ultimate fact rather than as an ultimate goal. It is the beginning of wisdom to be amazed at the fact of our being free.

God is not a hypothesis derived from logical assumptions, but an immediate insight, self-evident as light. He is not something to be sought in the darkness with the light of reason. He is the light.

Our age is one in which usefulness is thought to be the chief merit of nature; in which the attainment of power, the utilization of its resources is taken to be the chief purpose of man in God's creation. Man has indeed become primarily a tool-making animal, and the world is now a gigantic tool box for the satisfaction of his needs.

I am commanded therefore I am.
