Life is doubt,And faith without doubt is nothing but death. - Miguel de Unamuno

"Those who believe that they believe in God, but without passion in their hearts, without anguish in mind, without uncertainty, without doubt, without an element of despair even in their consolation, believe only in the God idea, not God Himself."

"Life is doubt,And faith without doubt is nothing but death."

"If it is nothingness that awaits us, let us make an injustice of it; let us fight against destiny, even though without hope of victory."

"At times to be silent is to lie. You will win because you have enough brute force. But you will not convince. For to convince you need to persuade. And in order to persuade you would need what you lack: Reason and Right"

"Only he who attempts the absurd is capable of achieving the impossible."
