Charles Ellicott Commentary Proverbs 18:1

"He that separateth himself seeketh [his own] desire, And rageth against all sound wisdom." — Proverbs 18:1 (ASV)

Through desire a man, having separated himself ...—This should probably be rendered, The separatist seeks after his own desire, against all improvement he shows his teeth. The man of small mind is here described, who will only follow his own narrow aims, who holds himself aloof from men of wider views than his own, and will not join with them in the furtherance of philanthropic or religious plans, but rather opposes them with all his power, as he can see nothing but mischief in them. (For his temper of mind, compare John 7:47-49.)

Intermeddleth.— See above on Proverbs 17:14.
