Restrain an inordinate desire for knowledge, in which is found much anxiety and deception. Learned men always wish to appear so, and desire recognition of their wisdom. But there are many matters, knowledge of which brings little or no advantage to the soul.
Thomas a KempisFor things that worth little or nothing we care a lot; and we oversight what is necessary; because every man goes towards the exterior; and if he doesn't regain consciousness quickly, with pleasure remain involved in it.
Thomas a KempisWho is so wise as to have a perfect knowledge of all things? Therefore trust not too much to thine own opinion, but be ready also to hear the opinion of others. Thought thine own opinion be good, yet if for the love of God thou foregoest it, and followest that of another, thou shalt the more profit thereby.
Thomas a Kempis
