The wisdom of the world is that of which it is said, "I will destroy the wisdom of the wise (1 Cor. 1:19; cf. Is. 29:14), i.e. those whom the world calls wise." "The wisdom of the flesh is an enemy of God" (Rom. 8:7), and does not come from above. It is earthly, devilish and carnal (Jas. 3:15). This worldly wisdom consists in an exact conformity to the maxims and fashions of the world; a continual inclination towards greatness and esteem; and a subtle and endless pursuit of pleasure and self-interest, not in an uncouth and blatant way by scandalous sin, but in an astute, discreet, and deceitful way. Otherwise the world would no longer label it wisdom but pure licentiousness.
