366. And, indeed, what this philofopher in his Phædrus fpeaketh of the fuper-celestial region, and the divinity refident therein, is of a strain not to be relished or comprehended by vulgar minds; to wit, effence realy exiftent, object of intellect alone, without colour, without figure, without any tangible quality. He might very juftly conceive that fuch a defcription muft feem ridiculous to fenfual men.

367. As for the perfect intuition of divine things, that he fuppofeth to be the lot of pure fouls, beholding by a pure light, initiated, happy, free and unftained from those bodies, wherein we are now imprifoned like oysters. But in this mortal ftate, we must be fatisfy'd to make the best of those glympfes b) within our reach. It is Plato's remark in his Theætetus, that while we fit ftill we are never the wifer, but going into the river and moving up and down, is the way to difcover its depths and fhallows. If we exercife and beftir ourselves, we may even here difcover fomething.

368. The eye by long ufe comes to fee even in the darkest cavern: and there is no fubject so obscure, buṛ we may difcern fome glympfe of truth by long poring on it. Truth is the cry of all, but the game of a few. Certainly where it is the chief paffion, it doth not give way to vulgar cares and views; nor is it contented with a little ardour in the early time of life, active perhaps to purfue, but not fo fit to weigh and revife. He that would make a real progrefs in knowledge, muft dedicate his age as well as youth, the later growth as well as first fruits, at the altar of truth.
