John Trapp on Proverbs 12:15

Verſ. 15. The way of a fool is right in his own eyes] Hee thinks his own wit beſt,Arachne ap. Ovid. Conſilii ſatis eſt in me mihi, hee will not part with his Commonwealth of bables, for the Tower of London. And ſuch a fool is every natural men, Job 11.12. wiſe enough, haply in his generation (ſo is the Fox too) wiſe with ſuch a wiſdome, as (like the Oſtrich-wings) makes him out-run others upon earth, and in earthly things, but helps him never a whit towards heaven; nay hinders him, and hangs in his light, as it fared with the Phariſees, Matth. 21.31. Of ſuch it may bee ſaid, as Quintilian ſaid of ſome over-weeners of themſelves, that they might have proved excellent Scholars if they had not been ſo perſwaded already; ſo might many have been wiſe, if they had not been conceited of their own wiſdome; and ſaved, if not over-well perſwaded of their good eſtate to God-ward. They claſp and hug the barn of their own brain with the Ape, till they ſtrangle it.

—At parit ut vivat regnetque beatus. Hor. Ep. 2. Cogi poſſe negat.—

But hee that hearkneth to counſel is wiſe] Hee that ſuſpecting his own judgement, takes advice of wiſer than himſelf, ſeldome miſcarries. There is that ſelf-love in many, that they think their Mole-hill a Mountain, their Keſtril an Eagle, their Gooſe a Swan. And being ſelf-conceited, they love to bee flattered. Not ſo the wiſe man; hee knows that humanum eſt errare. And that Triſte mortalitatis privilegium eſt licere aliquando peccare. Hee is therefore glad of good counſel, and thankful for a ſeaſonable reproof. Let the righteous ſmite mee.
