"Omnes res creatæ sunt divinæ sapientiæ et potentiæ testes, divitiæ felicitatis numanæ ; ex harum usu bonitas Creatoris ; ex pulchritudine sapientia Domini; ex œconomia in conservatione, proportione, renovatione, potentia majestatis elucet. Earum itaque indagatio ab hominibus sibi relictis semper æstimata; a vere eruditis et sapientibus semper exculta; male doctis et barbaris semper inimica fuit." LINN.
