“The heart has its order, the mind has its own, which uses principles and demonstrations. The heart has a different one. We do not prove that we ought to be loved by setting out in order the causes of love; that would be absurd.”

“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 its reasons which reason knows not.”

“The infinite distance between body and mind symbolizes the infinitely more infinite distance between mind and charity, for charity is supernatural....Out of all bodies together we could not succeed in creating one little thought. It is impossible, and of a different order. Out of all bodies and minds we could not extract one impulse of true charity. It is impossible, and of a different, supernatural, order.”

“We know the existence of the infinite without knowing its nature, because it too has extension but unlike us no limits.But we do not know either the existence or the nature of God, because he has neither extension nor limits.”

“Love knows no limit to its endurance, no end to its trust, no fading of its hope; it can outlast anything. Love still stands when all else has fallen.”

“The heart has reasons that reason cannot know.”
