“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 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.”

“There are two ways of persuading men of the truths of our religion; one by the power of reason, the other by the authority of the speaker.We do not use the latter but the former. We do not say: 'You must believe that because Scripture, which says it, is divine,' but we say that it must be believed for such and such a reason. But these are feeble arguments, because reason can be bent in any direction.”

“We know that we are not dreaming, but, however unable we may be to prove it rationally, our inability proves nothing but the weakness of our reason, and not the uncertainty of all our knowledge as they maintain.”

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

“Our imagination so magnifies the present, because we are continually thinking about it, and so reduces eternity, because we do not think about it, that we turn eternity into nothing and nothing into eternity, and all this is so strongly rooted within us that all our reason cannot save us from it.”

“Two contrary reasons. We must begin with that, otherwise we cannot understand anything and everything is heretical. And even at the end of each truth we must add that we are bearing the opposite truth in mind.”
