“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.”

“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 make an idol of truth itself, for truth apart from charity is not God, but his image and an idol that we must not love or worship.”

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

“It is absurd of us to rely on the company of our fellows, as wretched and helpless as we are; they will not help us; we shall die alone.We must act then as if we were alone. If that were so, would we build superb houses, etc.? We should unhesitatingly look for the truth. And, if we refuse, it shows that we have a higher regard for men's esteem than for pursuing the truth.”

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

“As we cannot be universal by knowing everything there is to know about everything, we must know a little about everything, because it is much better to know something about everything than everything about something. Such universality is the finest. It would be still better if we could have both together, but, if a choice must be made, this is the one to choose. The world knows this and does so, for the world is often a good judge.”
