I preferred the weapons of dialectic to all the other teachings of philosophy, and armed with these, I chose the conflicts of disputation rather than the trophies of war.

The first key to wisdom is assiduous and frequent questioning.

The beginning of wisdom is found in doubting by doubting we come to the question, and by seeking we may come upon the truth.

Nothing can be believed unless it is first understood and that for any one to preach to others that which either he has not understood nor they have understood is absurd.

The Son of God took our nature, and in it took upon himself to teach us by both word and example even to the point of death, thus binding us to himself through love.

In comparing your sorrows with mine, you may discover that yours are in truth nought.. and so shall you come to bear them the more easily grateful that they are not worse.

Are you not moved to tears and bitter compassion, when you behold the only Son of God seized by the most impious, dragged away, mocked, scourged, buffeted, spit upon, crowned with thorns, hung upon the infamous cross between two thieves, finally in such a horrible and execrable manner suffering death, for your salvation and that of the world?

By doubting we are led to enquire, and by enquiry we perceive the truth.

Logic has made me hated in the world.

In fact we say that an intention is good, that is, right in itself, but that an action does not bear any good in itself but proceeds from a good intention. Whence when the same thing is done by the same man at different times, by the diversity of his intention, however, his action is now said to be good, now bad.

We call an intention good which is right in itself, but the action is good, not because it contains within it some good, but because it issues from a good intention.
