"The Pythagoreans had found in the astral order the proportions of the concordant musical scale... a harmonia... Thereby they created the most enchanting symbol of Greek cosmic piety: "harmony," issuing in the inaudible "music of the spheres," [as] the idealizing expression for the same fact of irrefragable order that astrology stresses less optimistically... Stoic philsophy strove to integrate the idea of destiny as propounded by contemporary astrology with the Greek concept of harmony: to the Stoics is the practical aspect of the harmony, i.e., its action as it affects terrestrial conditions and the short-lived beings here. And since the stellar movements are actuated by the cosmic and this logos functions in the world-process as providence (pronoia), it follows that in this wholly monistic system heimarmene itself is pronoia, that is, fate and divine providence are the same. The understanding of and willing consent to this fate... as the reason of the whole distinguishes the wise man, who bears adversity... as the price... for the harmony of the whole. The existence of the whole... is the ultimate and no further questionable, self-justifying end in this teleological scheme: for the sake of the cosmos its constituent parts exist... for the sake of the whole organism. Man... is by no means the highest mode of being, he is not the end of nature, and the cosmos is not for his sake."
