If reason be a gift of Heaven, and we can say as much of faith, Heaven has certainly made us two gifts not only incompatible, but in direct contradiction to each other. In order to solve the difficulty, we are compelled to say either that faith is a chimera or that reason is useless.
~ Denis Diderot, in A Philosophical Conversation

Reason is our Soules left hand, Faith is her right, …
~ John Donne

Invisible Pink Unicorns are beings of awesome mystical power. We know this because hey manage to be invisible and pink at the same time. Like all religions; the Faith of the Invisible Pink Unicorns is based upon both logic and faith. We have faith that they are pink; we logically know that they are invisible because we can’t see them.
~ Steve Eley

The majority of mankind is lazy-minded, incurious, absorbed in vanities, and tepid in emotion, and is therefore incapable of either much doubt or much faith.
~ T.S. Eliot, in his Introduction to Pascal’s Pensees

I do not feel obliged to believe that same God who endowed us with sense, reason, and intellect had intended for us to forgo their use.
~ Galileo Galilei

Proof is only applicable to very rarefied areas of philosophy and mathematics…. For the most part we are driven to acting on good evidence, without the luxury of proof. There is good evidence of the link between cause and effect. There is good evidence that the sun will rise tomorrow. There is good reason to believe my mother loves me and is not just fattening me up for the moment when she will pop arsenic into my tea. And there is good reason to believe in God. Very good reason. Not conclusive proof, but very good reason just the same…. I believe it is much harder to reject the existence of a supreme being than accept it.
~ Michael Green, in Faith for the Non-religious

Some things have to be believed to be seen.
~ Ralph Hodgson

A wise man, therefore, proportions his belief to the evidence.
~ David Hume, in An Enquiry Concerning Human Concerning Human Understanding

For the scientist who has lived by his faith in the power of reason, the story ends like a bad dream. He has scaled the mountains of ignorance; he is about to conquer the highest peak; as he pulls himself over the final rock, he is greeted by a band of theologians who have been sitting there for centuries.
~ Robert Jastrow, in God and the Astronomer

The more we know of God, the more unreservedly we will trust Him; the greater our progress in theology, the simpler and more childlike will be our faith.
~ J. Gresham Machen

Religion is fundamentally opposed to everything I hold in veneration—courage, clear thinking, honesty, fairness, and above all, love of the truth.
~ H. L. Menken

The faith that does not come from reason is to be doubted, and the reason that does not lead to faith is to be feared,
~ G. Campbell Morgan

Faith certainly tells us what the senses do not, but not the contrary of what they see; it is above, not against them.
~ Blaise Pascal

Faith is reason at rest in God.
~ Charles Haddon Spurgeon

God cannot be understood by logical reasoning but only by submission.
~ Leo Tolstoy, in Wise Thoughts for Every Day

It is impossible to reason without arriving at a Supreme Being. Religion is as necessary to reason, as reason is to religion.
~ George Washington
