|Matthew Henry's Concise Commentary|
18:1 If we would get knowledge and grace, we must try all methods of improving ourselves. 2. Those make nothing to purpose, of learning or religion, whose only design is to have something to make a show with. 3. As soon as sin entered, shame followed.
Verse 2. - A fool hath no delight in understanding. This may mean that he takes no pleasure in the wisdom of others, is self-opinionated; or, it may be, does not care for understanding in itself, apart from the use which he can make of it. Vulgate, "The fool receives not the words of wisdom;" Septuagint, "A man of no sense has no need of wisdom." To try to teach a fool is to cast pearls before swine, and to give that which is holy unto dogs. But that his heart may discover itself; i.e. his only delight is in revealing his heart, displaying his un-wisdom and his foolish thoughts, as in Proverbs 12:28; Proverbs 13:16; Proverbs 15:2. He thinks that thus he is showing himself superior to others, and benefiting the world at large. The LXX. gives the reason, "For rather by folly he is led."
Gill's Exposition of the Entire Bible
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.

Jamieson-Fausset-Brown Bible Commentary
2. that his heart … itself—that is, takes pleasure in revealing his folly (Pr 12:23; 15:2).
