Wisdom of this world

From Book Five of Augustine's The Confessions:

5.4.7 Can it be true, Lord God of Truth (Ps. 31.5 [Ps. 30.6]), that whoever possesses this mathematical and astronomical knowledge is already pleasing in your sight? Unhappy indeed is the man who has this knowledge, but does not know you; blessed is the man who knows you, even if he does not have this knowledge. But blessed indeed is he who knows you and who knows also mathematics and astronomy. He is not more blessed on their account; he is blessed on account of you alone, if having known you he honours you as God, and gives thanks to you, and does not dwindle away to nought in his own conceits (Rom. 1.21). A man who knows he possesses a tree, and gives thanks to you for the use he has of it, is better off, even if he does not know how high this tree is or how wide it spreads, than a man who measures it and counts all its branches, and yet neither possesses it, nor knows you or loves you, its Creator. In the same way, only a fool would doubt that a believer, even though he does not know the wheeling track of the Great Bear, yet owns the earth in all its riches and though poor, yet possesses all things (2Cor. 6.10) through his faith in you, who all things serve (Ps. 119.91 [Ps. 118.91]), is better off than one who measures the heavens and numbers the stars and weighs the elements, yet ignores you, who have appointed all things in their measure, their number, and their weight (Wisdom 11.21).
