John Trapp on Ecclesiastes 8:17

Verſ. 17. That a man cannot finde out the work] No not the wiſeſt that is; the very beſt Empirick in this kinde cannot. Let him labour never ſo much to finde it, hee ſhall but bee toſſed in a Labyrinth, or as a wayfaring man in a deſert.Granger. If a man cannot define any thing becauſe the forms of things are unknown, if hee know not the creatures themſelves, ab imo ad ſummum, from the loweſt to the higheſt, neither ſhall hee know the reaſons and manner of them. As a man may look on a Trade, and never ſee the myſtery of it, hee may look on artificial things, pictures, watches, &c. and yet not ſee the Art whereby they are made: As a man may look on the letter, and never underſtand the ſenſe: So it is here, and wee muſt content our ſelves with a learned ignorance. Si nos non intelligimus quid quare fiat, Aug. in Pſal. 148. debeamus hoc providentiae quod non fiat ſine cauſa. If wee underſtand not why any thing is done, let us owe this duty to Providence, to bee aſſured that it is not done without cauſe.
