“The heart has reasons that reason cannot know.”

“The heart has its reasons which reason knows not.”

“We know the truth not only through our reason but also through our heart. It is through the latter that we know first principles, and reason, which has nothing to do with it, tries in vain to refute them.”

“We know the truth, not only be the reason, but also be the heart.”

“At the far end of this infinite distance a coin is being spun which will come down heads or tails. How will you wager? Reason cannot make you choose either, reason cannot prove either wrong.”

“There is nothing so consistent with reason as this denial of reason.”

“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.”
