A fool hath no delight in understanding, but that his heart may discover itself. Proverbs 18:2

This could be translated, a fool has no interest in understanding but to reveal his/her own innermost mind. Note that there is a choice. The person could choose understanding or his/her own mind. Knowing how the human mind works, this isn’t a surprising choice.

The human mind is incapable of rational thought on its own. Rational thought requires a true premise that leads to a true conclusion. On its own, the human mind cannot generate a true premise. Where would a true premise be found. A premise is a claim. It must be true. How do you prove the claim true? With another claim? How do you prove that claim true? You can’t without Divine revelation. Truth is only available in Jesus Christ. In Him is hidden all knowledge.

“The fear of the LORD is the beginning of knowledge: but fools despise wisdom and instruction.” Proverbs 1:7

Here, we have the same distinction made, but this one is between those who fear (respect) the Lord and those who despise wisdom and instruction.

Therefore, when any person looks into his or her own mind for knowledge, that person becomes a fool. Understanding comes from God. It can’t be found in one’s own mind. “The fear of the LORD is the beginning of wisdom: and the knowledge of the holy is understanding.” Proverbs 9:10 “The fear of the LORD is the beginning of wisdom: a good understanding have all they that do his commandments: his praise endureth for ever.” Psalms 111:10
