“I will tell you,” he said. “The lovers of knowledge are conscious that the soul was simply fastened and glued to the body—until philosophy freed her, she could only view real existence through the bars of a prison, not in and through herself; she was wallowing in the mire of every sort of ignorance, and by reason of lust had become the principal accomplice in her own captivity.” And a little later Socrates says: “The soul of the true philosopher thinks that she ought not to resist this deliverance (which philosophy offers), and therefore abstains from pleasures and desires and pains and fears, so far as she is able.”
Somewhat earlier in the dialogue Socrates had stated in still more emphatic terms the necessity of putting the body aside if man’s soul would attain real knowledge:[203] “For if while in company with the body the soul cannot have pure knowledge, one of two things follows—either knowledge is not to be attained at all, or if at all, after death. For then, and not till then, the soul will be parted from the body and exist in herself alone. In this present life, I reckon that we make the nearest approach to knowledge when we have the least possible intercourse or communion with the body, and are not surfeited with the bodily nature, but keep ourselves pure until the hour when God himself is pleased to release us. And thus having got rid of the foolishness of the body we shall be pure and shall hold converse with the pure, and know of ourselves the clear light everywhere, which is no other than the light of truth.” As the phrase, “until the hour when God himself is pleased to release us,” shows, man might not hasten the time of his release by his own act. And in other places, in familiar ways, Plato teaches that man may not desert the station where god has set him on guard until the command is given.
Finally in the Cratylus,[204] where Socrates in discussing the origin and nature of language indulges in some serious fooling in connection with the name of the soul (ψυχή), he says that he imagines that those who first gave the soul its name “psyche,” (ψυχή), wished to express the truth that the soul when in the body is the source of life, and gives the body the ability to breathe and revive, and that when this power fails the body, then it perishes and dies. As for body, he reminds his interlocutor that that word (σῶμα) is variously interpreted, some saying that it is the grave (σῆμα) of the soul, which may be regarded as in a tomb during this present life; and he adds that the Orphic poets were probably the ones who invented the name, for they had the notion that the embodied soul is suffering punishment for sin, and that the body is a prison in which the soul is incarcerated until the penalty of sin is paid. Likewise in the Gorgias[205] Socrates refers to the same Orphic idea and quotes a verse from Euripides: “Who knows whether life be not death and death life?” That is, this death in life is due to the body which tends to strangle the soul. Only when the reasoning soul has escaped from this tomb of the flesh can it really live. This is the reason why the true philosopher is always pursuing death in the sense that he is trying to free his soul, so far as may be, from the concerns of the body that it may enjoy life at its best.[206]
I have used Plato’s own words thus extensively for they set forth more eloquently than any words of mine the essential features of his doctrine. It requires no argument to show how great his debt to the Orphics and Pythagoreans was. But we cannot fail to see that he went far beyond his predecessors, for to their emotional belief in the immortality of the soul he gave an intellectual basis, by showing that the rational soul is of the same nature and substance as the Absolute, and therefore immortal and ever striving to apprehend the Absolute to which it belongs. In place of the external purifications and simple taboos which made up the Orphic course of life, Plato substitutes a noble discipline, reminding us of St. Paul—a discipline which has for its aim nothing less than the likening of man’s soul to God. When Plato teaches that man must begin his immortality here “by the practice of death,” we now see that he really means the practice of life; for life can only begin when the soul is released from its bodily tomb.
From the Orphics and Pythagoreans Plato adopted also the doctrine of the transmigration of souls. According to his view a thousand years—ten times the longest span of human life—elapsed between death and rebirth, during which the wicked received their ten-fold punishment and the righteous their like reward. When the time to return on earth came around, the souls were allowed to choose their new life as they pleased, only the wicked souls, “which had never seen the truth,” could not pass into the bodies of men. The choice made and their next destiny determined, the souls passed to the plain of Forgetfulness where each must drink of the river of Lethe; in the darkness of midnight there was an earthquake and thunderstorm, and the souls were driven, like shooting stars, to their birth. Ten thousand years were required to complete the round of rebirths and to allow the soul to return to its heavenly home. But the soul of a philosopher, “guileless and true,” might secure release after three rebirths if each time he had chosen the higher life. Some incurable sinners were not allowed to return to earth, but when their souls approached the mouth of the cavern which led to the upper world, the mouth gave a mighty roar and drove them back, while fiends tortured them with all the sufferings which a fertile imagination could devise. The path of salvation therefore lay in following righteousness and justice, in choosing the good, that is, in true philosophy. At the close of the Republic Socrates relates the vision of Er the Pamphylian whose soul returned with a report of the other world, and so concludes: “And thus, Glaucon, the tale has been saved and has not perished, and will save us if we are obedient to the word spoken; and we shall pass safely over the river of Forgetfulness and our soul will not be defiled. Wherefore my counsel is, that we hold fast ever to the heavenly way and follow after justice and virtue always, considering that the soul is immortal and able to endure every sort of good and every sort of evil. Thus shall we live dear to one another and to the gods, both while remaining here and when, like conquerors in the games who go round to gather gifts, we receive our reward. And it shall be well with us both in this life and in the pilgrimage of a thousand years which we have been describing.”[207]
With regard to the ultimate fate of the soul Plato is not wholly clear; but apparently he held that with the exception of those who had done unpardonable wrongs the souls of men, when their wanderings and rebirths were over and they had attained to purity, returned to God, to the universal reason; probably, however, he thought of their return as being without loss of individuality, for Plato lays so much stress on the individual soul that we cannot believe that he would have allowed it to lose its personality in the Absolute.
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.
But in this discussion of Plato’s religious philosophy we have left one important subject untouched—the problem of evil. This was a question which a mind so acute and inquisitive as Plato’s could not finally avoid. Of the presence of evil in the world he was fully aware, and indeed he maintained that evils must always exist, for there must remain something antagonistic to the good; and since evils cannot exist in heaven the earth is their abode, from which man must try to escape.[208] On the source of evil, however, he touches only in the Statesman and the Timaeus;[209] in both the question is intimately connected with his theories of creation, which he sets forth in myth. But leaving aside the Platonic imagery, I will simply remind you that earlier in this lecture we saw that Plato conceived the world we know as dual—the phenomenal world known through the senses and the world of ideas apprehended by reason. Now the ideas alone have Being; but the phenomenal world is always in a state of Becoming, that is, of coming into being and of ceasing to be; it is both temporal and imperfect. Obviously there must be some principle, parallel in a way to the perfect and eternal ideas, such that it can receive them, and by its participation in them bring the imperfect sensible world into transitory existence. This principle is to Plato the material element. Now since he ascribes to the ideas alone real existence, that is, Being, the material principle must be Not-being. It is the negative substratum of all sensible phenomena, itself invisible, without form or characteristic, or in Plato’s words “the receptacle, and in a manner, the nurse of all generation” for, although itself formless, it is capable of taking on all the forms which the ideas may impose upon it. Plato himself could not avoid the difficulties which such a material substratum raises, and at times he is forced to speak as if it were something real in itself, having an existence beside the ideas. But his true notion seems to be that matter is mere negation, like the Aristotelian στέρησις, something which cannot be grasped by the intellect, as can the ideas, or perceived by the senses, as can the phenomenal world; it is identical with space. Of course when Plato talks about this negative principle, he inevitably speaks as if we could know something about it.[210]
