Thomas Aquinas and A. G. Sertillanges wrote treatise on the merits of an intellectual life, one dedicated to the pursuit of truth and the path to wisdom. The advice they offer is worthy of consideration by anyone who wishes to be knowledgeable, wise, and dedicated to a life of learning.
Thomas Aquinas was an Italian Dominican theologian, philosopher, and medieval Scholastic during the 13th century. In his “Letter to Brother John,” he gave the following words of advice on how to gain something from the "treasure-house of knowledge," and, subsequently, how Brother John could attain his every desire.
"I counsel you to be slow to speak and slow to take the speaker's stand. Embrace purity of mind; do not neglect prayer; cherish your cell most of the time, if you wish to be admitted to the vintage-room [of knowledge]. Be friendly to all men; do not be curious about the private activities of other people; do not try to be overfamiliar with anyone, for too much familiarity breed contempt and provides an opportunity for neglecting one's studies."
