The Confessions And Letters Of St by St. Augustine
Chapter IV.--That the Knowledge of Terrestrial and Celestial Things Does Not Give Happiness, But the Knowledge of God Only.
7. Doth, then, O Lord God of truth, whosoever knoweth those things therefore please Thee? For unhappy is the man who knoweth all those things, but knoweth Thee not; but happy is he who knoweth Thee, though these he may not know. But he who knoweth both Thee and them is not the happier on account of them, but is happy on account of Thee only, if knowing Thee he glorify Thee as God, and gives thanks, and becomes not vain in his thoughts. But as he is happier who knows how to possess a tree, and for the use thereof renders thanks to Thee, although he may not know how many cubits high it is, or how wide it spreads, than he that measures it and counts all its branches, and neither owns it nor knows or loves its Creator; so a just man, whose is the entire world of wealth, and who, as having nothing, yet possesseth all things by cleaving unto Thee, to whom all things are subservient, though he know not even the circles of the Great Bear, yet it is foolish to doubt but that he may verily be better than he who can measure the heavens, and number the stars, and weigh the elements, but is forgetful of Thee, |who hast set in order all things in number, weight, and measure.|
