Verse 15. - The way of a fool is right in his own eyes; i.e. in his own judgment (Proverbs 3:7: 16:2). The second clause is best translated, as in the Revised Version, "But he that is wise hearkeneth unto counsel," distrusting his own unaided judgment, which might lead him astray (Proverbs 13:10; Proverbs 14:12; Proverbs 16:25; Proverbs 21:2; comp. Ecclus. 35:19; Tobit 4:18). Theognis, 221, etc. -

Ὅς τις τοι δοκέει τὸν πλησίον ἴδμεναι οὐδὲν
Ἀλλ αὐτὸς μοῦνος ποικίλα δήνε ἔχειν
Κεῖνός γ ἄφρων ἐστὶ νόου βεβλαμμένος ἐσθλοῦ
Ἴσως γὰρ πάντες ποικίλ ἐπιστάμεθα

"Who thinks his neighbour nothing knows,
And he alone can see,
Is but a fool, for we perhaps
Know even more than he."

12:14. When men use their tongues aright, to teach and comfort others, they enjoy acceptance through Christ Jesus; and the testimony of their conscience, that they in some measure answer the end of their being. 15. A fool, in the sense of Scripture, means a wicked man, one who acts contrary to the wisdom that is from above. His rule is, to do what is right in his own eyes.The way of a fool is right in his own eyes,.... Whether it be the way of open profaneness, or self-righteousness, it appears to him to be the right way; it seems to him a very plain one, and he finds it pleasant; and, trusting to carnal sense, corrupt reason, and a false judgment, and having a high opinion of himself and his own knowledge, never asks after the right way, nor takes the advice of others;

but he that hearkeneth unto counsel is wise; that asks advice and takes it of such who are men of age and experience, men of longer standing, and are wiser than himself; who consults the word of God about the right way of walk, worship, and salvation, and makes the testimonies of God the men of his counsel, which are able to make him wise unto salvation; who hearkens to the counsel of Gospel ministers, and obeys it; and especially to Jesus Christ the wonderful Counsellor, and to the advice he gives, Revelation 3:18; and who not only hears his words, but does them; such an one is a wise man, Matthew 7:24.
