Rest from inordinate desire of knowledge, for therein is found much distraction and deceit. Those who have knowledge desire to appear learned, and to be called wise. Many things there are to know which profiteth little or nothing to the soul. And foolish out of measure is he who attendeth upon other things rather than those which serve to his soul’s health. Many words satisfy not the soul, but a good life refresheth the mind, and a pure conscience giveth great confidence towards God.
If it seemeth to thee that thou knowest many things, and understandest them well, know also that there are many more things which thou knowest not. Be not high−minded, but rather confess thine ignorance. Why desirest thou to lift thyself above another, when there are found many more learned and more skilled than thou? If thou wilt know and learn anything with profit, love to be thyself unknown and to be counted for nothing.
That is the highest and most profitable lesson, when a man truly knoweth and judgeth lowly of himself. To account nothing of one’s self, and to think always kindly and highly of others, this is great and perfect wisdom. Even shouldest thou see thy neighbor sin openly or grievously, yet thou oughtest not to reckon thyself better than he, for thou knowest not how long thou shalt keep thine integrity. All of us are weak and frail; hold thou no man more frail than thyself.
Thomas à Kempis – The Imitation of Christ
