If I should know all things that are in the world, and should not be in charity: what help would it be to me in the sight of God, who will judge me by my deeds?
2. Leave off that excessive desire of knowing: because there is found therein much distraction and deceit.

If it seems to thee that thou knowest many things, and understandest them well enough: know at the same time that there are many more things of which thou art ignorant.
