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

“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.”

“The heart has reasons that reason cannot know.”

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

“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.”

“Truth is so obscure in these times, and falsehood so established, that, unless we love the truth, we cannot know it.”

“We desire truth and find within ourselves only uncertainty.”
