=247.= The second proof ‘that gods exist’ is particularly associated with the name of Chrysippus; it may be summed up by saying ‘there must be a Being higher than man.’ We begin by assuming that reason is the highest power in the universe[48]; an axiom which is always subject to limitation on account of the existence of ‘natural necessity.’ According to the Stoics, reason is common to gods and men; if, for the sake of argument, this is denied, then reason is possessed by men alone, for we can certainly find no better name than ‘god’ for higher reasoning beings[49]. If then there exists something greater than human reason can produce, it must be the work of some reasoning being greater than man, that is, it must be the work of the gods. But the heavenly constellations are such a work; therefore they are the work of the gods, and therefore gods exist[50]. To this argument two others are supplementary. First, human reason itself must be derived from some source, and what other can we name but the deity[51]? Secondly, if there are no gods, man must be the supreme being; but such a claim is an arrogant infatuation[52]. The same arguments are attributed in substance to Zeno[53]; nay, so cogent are they that they are in part accepted even by Epicurus[54]. [Sidenote: The proofs from the elements and the universe.] =248.= There follow two proofs connected with gradations in the scale of being. Earth and water are the two lower and grosser elements; and since temperament depends greatly upon climate, we find that men and the animals are all of somewhat heavy character. Air and fire are the higher and more refined elements; how then can we think otherwise than that they are the home of more lofty beings[55]? Then again the universe is either a simple or a composite body. That it is not composite is shown by the harmony (συμπάθεια, _concentus_) of its parts; it is therefore simple. A simple body must be held together by spirit in some one of its grades, either as unity, growth, or soul. Bodies held together merely by unity, like stones or logs, admit of very simple changes only; but the universe admits of every kind of change and development, and yet keeps together; it must therefore be held together by spirit in its highest grade, that is by soul and by reason. Being a whole, it must be greater than its parts, and include all that its parts possess. But a nature greater than man, and possessing soul and reason, is god[56].
