“Pity me that the heart is slow to learnWhat the swift mind beholds at every turn.”

“love is a deeper seasonthan reason;my sweet one”

“The invisible and the non-existent look very much alike.”

“Theology is ignorance with wings.”

“All our knowledge begins with the senses, proceeds then to the understanding, and ends with reason. There is nothing higher than reason.”

“Though I do not believe in the order of things, still the sticky little leaves that come out in the spring are dear to me, the blue sky is dear to me, some people are dear to me, whom one loves sometimes, would you believe it, without even knowing why; some human deeds are dear to me, which one has perhaps long ceased believing in, but still honors with one’s heart, out of old habit…”–Ivan Karamazov”

“I do not pretend to be able to prove that there is no God. I equally cannot prove that Satan is a fiction. The Christian god may exist; so may the gods of Olympus, or of ancient Egypt, or of Babylon. But no one of these hypotheses is more probable than any other: they lie outside the region of even probable knowledge, and therefore there is no reason to consider any of them.”

“I mean, you could claim that anything’s real if the only basis for believing in it is that nobody’s proved it doesn’t exist!”

“Reason excludes faith,” Alessandro responded, watching the blood-red mite as it made a dash for the rim. “It’s deliberately limited. It won’t function with the materials of religion. You can come close to proving the existence of God by reason, but you can’t do it absolutely. That’s because you can’t do anything absolutely by reason. That’s because reason depends on postulates. Postulates defy proof and yet they are essential to reason. God is a postulate. I don’t think God is interested in the verification of His existence, and, therefore, neither am I. Anyway, I have professional reasons to believe. Nature and art pivot faithfully around God. Even dogs know that.”

“And here is the point, about myself and my co-thinkers. Our belief is not a belief. Our principles are not a faith. We do not rely solely upon science and reason, because these are necessary rather than sufficient factors, but we distrust anything that contradicts science or outrages reason. We may differ on many things, but what we respect is free inquiry, openmindedness, and the pursuit of ideas for their own sake.”

“I am an atheist, out and out. It took me a long time to say it. I’ve been an atheist for years and years, but somehow I felt it was intellectually unrespectable to say one was an atheist, because it assumed knowledge that one didn’t have. Somehow, it was better to say one was a humanist or an agnostic. I finally decided that I’m a creature of emotion as well as of reason. Emotionally, I am an atheist. I don’t have the evidence to prove that God doesn’t exist, but I so strongly suspect he doesn’t that I don’t want to waste my time.”

“Reason is a whore, the greatest enemy that faith has; it never comes to the aid of spiritual things, but more frequently than not struggles against the divine Word, treating with contempt all that emanates from God.”

“If we submit everything to reason our religion will be left with nothing mysterious or supernatural. If we offend the principles of reason our religion will be absurd and ridiculous . . . There are two equally dangerous extremes: to exclude reason, to admit nothing but reason.”

“We know enough at this moment to say that the God of Abraham is not only unworthy of the immensity of creation; he is unworthy even of man.”

“Man is manifestly not the measure of all things. This universe is shot through with mystery. The very fact of its being, and of our own, is a mystery absolute, and the only miracle worthy of the name.”
