It is the duty of the human understanding to understand that there are things which it cannot understand, and what those things are. Human understanding has vulgarly occupied itself with nothing but understanding, but if it would only take the trouble to understand itself at the same time it would simply have to posit the paradox.

...a human being not only can choose but... he must choose... for in this way God retains His honor while at the same time has a fatherly concern for humankind. Though God has lowered Himself to being that which can be chosen, yet each person must on his part choose. God is not mocked. Therefore the matter stands thus: If a person avoids choosing, this is the same as the presumption of choosing the world.

Truth is not introduced into the individual from without, but was within him all the time.

This, then, is the ultimate paradox of thought: to want to discover something that thought itself cannot think.

Without risk, faith is an impossibility.

The most painful state of being is remembering the future, particularly the one you'll never have.

Hope is passion for what is possible.
