It is the heart which experiences God, and not the reason. This, then, is faith: God felt by the heart, not by the reason. Blaise Pascal

At the heart of science is an essential tension between two seemingly contradictory attitudes - an openness to new ideas, no matter how bizarre or counterintuitive they may be, and the most ruthless skeptical scrutiny of all ideas, old and new. This is how deep truths are winnowed from deep nonsense. Of course, scientists make mistakes in trying to understand the world, but there is a built-in error-correcting mechanism: The collective enterprise of creative thinking and skeptical thinking together keeps the field on track. Carl Sagan

That language is an instrument of human reason, and not merely a medium for the expression of thought, is a truth generally admitted. George Boole

This is the perpetual and pitiful tragedy of the practical man in practical affairs. He always begins with a flourish of contempt for what he calls theorizing and what people who can do it call thinking. He will not wait for logic - that is, in the most exact sense, he will not listen to reason. It will therefore appear to him an idle and ineffectual proceeding to say that there is a reason for his present failure. Nevertheless, it may be well to say it, and to try and make it clear even to him. Gilbert Keith Chesterton

The supreme function of reason is to show man that some things are beyond reason. Blaise Pascal
