Albert Barnes Commentary Proverbs 12:1

"Whoso loveth correction loveth knowledge; But he that hateth reproof is brutish." — Proverbs 12:1 (ASV)

Brutish - Dumb as a brute beast. The difference between man and brute lies chiefly in the capacity of the former for progress and improvement, and that capacity depends upon his willingness to submit to discipline and education. Compare Psalms 49:12.
