EVERY man naturally desires knowledge; but what good is knowledge without fear of God? Indeed a humble rustic who serves God is better than a proud intellectual who neglects his soul to study the course of the stars. He who knows himself well becomes mean in his own eyes and is not happy when praised by men.
If I knew all things in the world and had not charity, what would it profit me before God Who will judge me by my deeds?
Shun too great a desire for knowledge, for in it there is much fretting and delusion. Intellectuals like to appear learned and to be called wise. Yet there are many things the knowledge of which does little or no good to the soul, and he who concerns himself about other things than those which lead to salvation is very unwise.
Many words do not satisfy the soul; but a good life eases the mind and a clean conscience inspires great trust in God.
The more you know and the better you understand, the more
severely will you be judged, unless your life is also the more holy. Do not be
proud, therefore, because of your learning or skill. Rather, fear because of
the talent given you. If you think you know many things and understand them
well 
enough, realize at the same time that there is much you do
not know. Hence, do not affect wisdom, but admit your ignorance. Why prefer
yourself to anyone else when many are more learned, more cultured than you?
If you wish to learn and appreciate something worth while, then love to be unknown and considered as nothing. Truly to know and despise self is the best and most perfect counsel. To think of oneself as nothing, and always to think well and highly of others is the best and most perfect wisdom. Wherefore, if you see another sin openly or commit a serious crime, do not consider yourself better, for you do not know how long you can remain in good estate. All men are frail, but you must admit that none is more frail than yourself.
HAPPY is he to whom truth manifests itself, not in signs and words that fade, but as it actually is. Our opinions, our senses often deceive us and we discern very little.
What good is much discussion of involved and obscure matters
when our ignorance of them will not be held against us on Judgment Day? Neglect
of things which are profitable and necessary and 
undue
concern with those which are irrelevant and harmful, are great folly.
We have eyes and do not see.
What, therefore, have we to do with questions of philosophy? He to whom the Eternal Word speaks is free from theorizing. For from this Word are all things and of Him all things speak -- the Beginning Who also speaks to us. Without this Word no man understands or judges aright. He to whom it becomes everything, who traces all things to it and who sees all things in it, may ease his heart and remain at peace with God.
O God, You Who are the truth, make me one with You in love everlasting. I am often wearied by the many things I hear and read, but in You is all that I long for. Let the learned be still, let all creatures be silent before You; You alone speak to me.
The more recollected a man is, and the more simple of heart he becomes, the easier he understands sublime things, for he receives the light of knowledge from above. The pure, simple, and steadfast spirit is not distracted by many labors, for he does them all for the honor of God. And since he enjoys interior peace he seeks no selfish end in anything. What, indeed, gives more trouble and affliction than uncontrolled desires of the heart?
A good and devout man arranges in his mind the things he has
to do, not according to the whims of evil inclination but according to the
dictates of 
right reason. Who is forced to struggle more than he who
tries to master himself? This ought to be our purpose, then: to conquer self,
to become stronger each day, to advance in virtue.
Every perfection in this life has some imperfection mixed with it and no learning of ours is without some darkness. Humble knowledge of self is a surer path to God than the ardent pursuit of learning. Not that learning is to be considered evil, or knowledge, which is good in itself and so ordained by God; but a clean conscience and virtuous life ought always to be preferred. Many often err and accomplish little or nothing because they try to become learned rather than to live well.
If men used as much care in uprooting vices and implanting virtues as they do in discussing problems, there would not be so much evil and scandal in the world, or such laxity in religious organizations. On the day of judgment, surely, we shall not be asked what we have read but what we have done; not how well we have spoken but how well we have lived.
Tell me, where now are all the masters and teachers whom you
knew so well in life and who were famous for 
their
learning? Others have already taken their places and I know not whether they
ever think of their predecessors. During life they seemed to be something; now
they are seldom remembered. How quickly the glory of the world passes away! If
only their lives had kept pace with their learning, then their study and
reading would have been worth while.
How many there are who perish because of vain worldly knowledge and too little care for serving God. They became vain in their own conceits because they chose to be great rather than humble.
He is truly great who has great charity. He is truly great who is little in his own eyes and makes nothing of the highest honor. He is truly wise who looks upon all earthly things as folly that he may gain Christ. He who does God's will and renounces his own is truly very learned.
