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.
