Proverbs 12:15

The way of a fool, &c.— The danger of self-love and self-conceit is here represented; which have ever this effect, that they make men slight, if not reject, good counsel, out of a vain opinion that none can advise them better than themselves; which is, to follow the direction of a fool: for it is as certain a note of folly to rely wholly upon a man's own judgment, as it is of prudence to hearken to the advice of others.
