But he [John Henry Newman] also saw that a love of truth and therefore of argument was part of what characterized and formed the heart. The heart, let me emphasize, that speaks to other hearts. The man who loves something wants to know about it. He wants, as far as the subject allows, to think about it, to analyze it, to understand it deeply. He will use that knowledge to come to its defense when it is misunderstood or misinterpreted or publicly derided or denied. This is even truer when he loves someone. If he doesn’t want to know, he doesn’t truly love.
