“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.”

“Those who believe they believe in God, but without passion in the heart, without anguish of mind, without uncertainty, without doubt, and even at times without despair, believe only in the idea of God, and not in God himself.”

“Life is doubt,And faith without doubt is nothing but death.”

“We live by revelation, as Christians, as artists, which means we must be careful never to get set into rigid molds. The minute we begin to think we know all the answers, we forget the questions, and we become smug like the Pharisee who listed all his considerable virtues, and thanked God that he was not like other men.Unamuno might be describing the artist as well as the Christian as he writes, "Those who believe they believe in God, but without passion in the heart, without anguish of mind, without uncertainty, without doubt, and even at times without despair, believe only in the idea of God, and not in God himself.”

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

“The vanity of the passing world and love are the two fundamental and heart-penetrating notes of true poetry. And they are two notes of which neither can be sounded without causing the other to vibrate. The feeling of the vanity of the passing world kindles love in us, the only thing that triumphs over the vain and transitory, the only thing that fills life again and eternalizes it.”

“Consciousness (conscientia) is participated knowledge, is co-feeling, and co-feeling is com-passion. Love personalizes all that it loves. Only by personalizing it can we fall in love with an idea. And when love is so great and so vital, so strong and so overflowing, that it loves everything, then it personalizes everything and discovers that the total All, that the Universe, is also a person possessing a Consciousness, a Consciousness which in its turn suffers, pities, and loves, and therefore is consciousness. And this Consciousness of the Universe, which a love, personalizing all that it loves, discovers, is what we call God.”
