8 And yet, that I may not seem to have no opinion on subjects of this kind, that I may not appear when asked to have nothing to offer, I may say, What if the primal matter which has been diffused through the four elements of the universe, contains the causes of all miseries inherent in its own constitution? What if the movements of the heavenly bodies produce these evils in certain signs, regions, seasons, and tracts, and impose upon things placed under them the necessity of various dangers?
What if, at stated intervals, changes take place in the universe, and, as in the tides of the sea, prosperity at one time flows, at another time ebbs, evils alternating with it? What if those impurities of matter which we tread trader our feet have this condition imposed upon them, that they give forth the most noxious exhalations, by means of which this our atmosphere is corrupted, and brings pestilence on our bodies, and weakens the human race? What if— and this seems nearest the truth— whatever appears to us adverse, is in reality not an evil to the world itself?
And what if, measuring by our own advantages all things which take place, we blame the results of nature through ill-formed judgments? Plato, that sublime head and pillar of philosophers, has declared in his writings, that those cruel floods and those conflagrations of the I world are a purification of the earth; nor did that wise man dread to call the overthrow of the human race, its destruction, ruin, and death, a renewal of things, and to affirm that a youthfulness, as it were, was secured by this renewed strength.
