A fool may pretend to understanding, and to seek and intermeddle with the means of it, but, 1. He has no true delight in it; it is only to please his friends or save his credit; he does not love his book, nor his business, nor his Bible, nor his prayers; he would rather be playing the fool with his sports. Those who take no pleasure in learning or religion will make nothing to purpose of either. No progress is made in them if they are a task and a drudgery. 2. He has no good design in it, only that his heart may discover itself, that he may have something to make a show with, something wherewith to varnish his folly, that that may pass off the better, because he loves to hear himself talk.

A fool hath no delight in understanding,.... In natural understanding, and in the improvement of his mind in it; he delights not in books, nor in the conversation of men of learning and sense: or in spiritual understanding, in the understanding of spiritual things; these are foolishness to a natural man; nor does he delight in reading the Scriptures, nor in hearing the word, and attendance on it in the house of God, but is weary of such exercises;

but that his heart may discover itself; and the folly that is in it: such men only desire to have some knowledge and understanding, to make a show of it, that they may be thought to be wise, and to be capable of talking of things as if they understood them, when it is only to the exposing of themselves and their ignorance; some persons attain to no more learning and knowledge than just to be capable to show that they are fools. Or, "but in the discovery of his heart" (k); he delights in discovering that; not the wisdom, but the folly that is in it.

that his heart . . . itself--that is, takes pleasure in revealing his folly (Pro 12:23; Pro 15:2).
