** I'm thinking of this being the analogy (admittedly not right on point but good for pointing out how abandoning the study of nature / confidence in the senses will open the door for a flood of other problems:
For on whatever side you maintain that the bodies fail first, this side will be the gate of death for things, by this path will all the throng of matter cast itself abroad.

Moreover, since they do not pretend that all bodies press towards the centre, but only those of earth and liquid, the moisture of the sea and mighty waters from the mountains, and those things which are, as it were, enclosed in an earthy frame; but on the other hand, they teach that the thin breezes of air and hot fires at the same time are carried away from the centre, and that for this cause all the sky around is twinkling with stars, and the flame of the sun is fed through the blue tracts of heaven, because all the heat fleeing from the centre gathers itself together there; nor again can the topmost branches grow leafy upon trees, unless from the earth little by little each has food [supplied by nature, their thoughts are not at harmony with themselves. There must then be an infinite store of matter], lest after the winged way of flames the walls of the world suddenly fly apart, dissolved through the great void, and lest all else follow them in like manner, or the thundering quarters of the sky fall down from above, and the earth in hot haste withdraw itself from beneath our feet, and amid all the mingled ruin of things on earth and of the sky, whereby the frames of bodies are loosed, it pass away through the deep void, so that in an instant of time not a wrack be left behind, except emptied space and unseen first-beginnings. For on whatever side you maintain that the bodies fail first, this side will be the gate of death for things, by this path will all the throng of matter cast itself abroad.
