Man must learn to know the universe precisely as it is, or he cannot successfully find his place in it. A man should therefore use his reasoning faculty in all matters involving truth, and especially as concerning his religion. He must learn to distinguish between truth and error.
An acquaintanceship with the literature of the world may be won by any person who will devote half an hour a day to the careful reading of the best books. The habit of reading good books is one that gives great comfort in all the stages and among all the vicissitudes of life. The man who has learned to love good reading is never alone. His friends are the great ones of human history, and to them he may always go for stimulating and helpful communion. --GQ 71 (GQ is A Guide for Quorums of the Melchizedek Priesthood, 3rd Edition, 1930)
