Reason

The heart has its reasons which reason knows not.

Blaise Pascal

Question with boldness even the existence of a God; because, if there be one, he must more approve of the homage of reason, than that of blindfolded fear.

Thomas Jefferson

We know the truth, not only by the reason, but also by the heart.

Blaise Pascal

I was bold in the pursuit of knowledge, never fearing to follow truth and reason to whatever results they led, and bearding every authority which stood in their way.

Thomas Jefferson

It is the heart which perceives God and not the reason. That is what faith is: God perceived by the heart, not by the reason.

Blaise Pascal
