This account, I trust, for all its imperfections, is sufficient to indicate what a great advance Plato made in his concept of the spiritual life. Man’s reason is now made the means and agent of his spiritual ascent; the reasoning soul, by its own nature, strives to seek its own, and so finds its goal by virtue of its reason. The human will is not neglected in the Platonic system, but it is by no means made prominent. Man’s salvation is attained when the soul through the exercise of its reason has risen superior to its bodily prison, freed itself of the imperfections and evils which are necessarily associated with the body, and purified has attained to God’s likeness. In the preceding discussion I have used the word God freely, but it may fairly be asked how far such use is justified, and furthermore whether Plato was a pantheist or a polytheist. It is indeed somewhat difficult to answer these questions, for in many passages he speaks of the gods in the plural after the common manner, and in the Timaeus he especially provides for a multitude of gods secondary to the Absolute; in many other places he speaks of the Divine (τὸ θεῖον) or simply God (θεός). Sometimes he seems to conceive of God as a living personality; again God is apparently only the impersonal idea of the Good. Yet in spite of the fact that his expressions range from polytheism almost to monotheism, considering the sum total of his thought, we are justified in speaking of his idea of God. At the same time we must always understand that his thought admitted many gods, subordinate to the Absolute and included in it. But whatever the form of expression which he uses, Plato conceives of God as the giver of good alone. For him there is no deception or deceit in the divine; the chastening of man by God is always for the purpose of making man better, never to satisfy any punitive desire. The notion of “the envy of the gods,” which is so prominent in Aeschylus, Herodotus, and other writers of the fifth century, to Plato is abhorrent and inconceivable. Furthermore he makes the Divine, the idea of the Good, the measure of truth, not man, as Protagoras would have had him. His world therefore has a divine warrant of its validity; it is ordered by the mind of the good and just God, and not by the will of a debased divinity or by mere chance. Previous thinkers had made Justice the highest attribute of divinity; to this Plato added Goodness as the chief characteristic of God.
