"Q1 Must human faith be completed by reason, or not?"

“The purpose and cause of the incarnation was that He might illuminate the world by His wisdom and excite it to the love of Himself.”

“Q3 Is there any knowledge of things unseen, or not?”

“Sometimes I grieve for the house of the Paraclete, and wish to see it again. Ah, Philintus! does not the love of Heloise still burn in my heart? I have not yet triumphed over that happy passion. In the midst of my retirement I sigh, I weep, I pine, I speak the dear name of Heloise, pleased to hear the sound, I complain of the severity of Heaven. But, oh! let us not deceive ourselves: I have not made a right use of grace. I am thoroughly wretched. I have not yet torn from my heart deep roots which vice has planted in it. For if my conversion was sincere, how could I take a pleasure to relate my past follies? Could I not more easily comfort myself in my afflictions? Could I not turn to my advantage those words of God himself, If they have persecuted me, they will also persecute you; if the world hate you, ye know that it hated me also? Come Philintus, let us make a strong effort, turn our misfortunes to our advantage, make them meritorious, or at least wipe out our offences; let us receive, without murmuring, what comes from the hand of God, and let us not oppose our will to his. Adieu. I give you advice, which could I myself follow, I should be happy.”

“I have ventured to bring together various dicta of the holy fathers, as they came to mind, and to formulate certain questions which were suggested by the seeming contradictions in the statements. These questions ought to serve to excite tender readers to a zealous inquiry into truth and so sharpen their wits. The master key of knowledge is, indeed, a persistent and frequent questioning. Aristotle, the most clear-sighted of all the philosophers, was desirous above all things else to arouse this questioning spirit, for in his Categories he exhorts a student as follows: "It may well be difficult to reach a positive conclusion in these matters unless they be frequently discussed. It is by no means fruitless to be doubtful on particular points." By doubting we come to examine, and by examining we reach the truth.”
