One Must Love In Order To Know

Blaise Pascal, The Art of Persuasion:

I do not here speak of divine truths, which I shall take care not to comprise under the art of persuasion, because they are infinitely superior to nature: God alone can place them into the soul and in such a way as it pleases him. I know that he has desired that they should enter from the heart into the mind, and not from the mind into the heart, to humiliate that proud power of reasoning that pretends to the right to be the judge of the things that the will chooses; and to cure this inform will which is wholly corrupted by its filthy attachments. And thence it comes that whilst in speaking of human things, we say that it is necessary to know them before we can love them, which has passed into a proverb, the saints on the contrary say in speaking of divine things that it is necessary to love them in order to know them, and that we only enter truth through charity, from which they have made one of their most useful maxims.
