"A desire for truth is by no means a need for certitude and it would be unwise to confuse one with the other."

The person who risks nothing, does nothing, has nothing, is nothing, and becomes nothing. He may avoid suffering and sorrow, but he simply cannot learn, feel, change, grow or love. Chained by his certitude, he is a slave; he has forfeited his freedom. Only the person who risks is truly free.
