All kinds of knowledge not borrowed from sense-reality are grounded on such thoughts. The whole of mathematics consists of them. He would be a bad geometrician who could only bring into mathematical relations what he can see with his eyes and touch with his hands. Thus we have thoughts which do not originate in perishable nature, but arise out of the spirit. And it is these that bear in them the mark of eternal truth. What mathematics teach will be eternally true, even if to-morrow the whole cosmic system should fall into ruins and an entirely new one arise. Conditions might prevail in another cosmic system, to which our present mathematical truths would not be applicable, but these would be none the less true in themselves.
It is only when the soul is alone with itself that it can bring forth these eternal truths. It is at these times related to the true and eternal, and not to the ephemeral and apparent. Hence Socrates says: "When the soul returning into itself reflects, it goes straight to what is pure and everlasting and immortal and like unto itself; and being related to this, cleaves unto it when the soul is alone, and is not hindered. And then the soul rests from its mistakes, and is like unto itself, even as the eternal is, with whom the soul is now in touch. This state of soul is called wisdom.... Look now whether it does not follow from all that has been said, that the soul is most like the divine, immortal, reasonable, unique, indissoluble, what is always the same and like unto itself; and that on the other hand the body most resembles what is human and mortal, unreasonable, multiform, soluble, never the same nor remaining equal to itself.... If, therefore, this be so, the soul goes to what is like itself, to the immaterial, to the divine, immortal, reasonable. There it attains to bliss, freed from error and ignorance, from fear and undisciplined love and all other human evils. There it lives, as the initiates say, for the remaining time truly with God."
It is not within the scope of this book to indicate all the ways in which Socrates leads his friends to the eternal. They all breathe the same spirit. They all tend to show that man finds one thing when he goes the way of transitory sense-perception, and another when his spirit is alone with itself. It is to this original nature of spirit that Socrates points his hearers. If they find it, they see with their own spiritual eyes that it is eternal. The dying Socrates does not prove the immortality of the soul, he simply lays bare the nature of the soul. And then it comes to light that growth and decay, birth and death, have nothing to do with the soul. The essence of the soul lies in the true, and this can neither come into being nor perish. The soul has no more to do with the becoming than the straight has with the crooked. But death belongs to the becoming. Therefore the soul has nothing to do with death. Must we not say of what is immortal, that it admits of mortality as little as does the straight of the crooked? Starting from this point, "must we not ask," adds Socrates, "that if the immortal is imperishable, is it not impossible for the soul to come to an end when death arrives? For from what has been already shown, it does not admit of death, nor can it die any more than three can be an even number."
Let us review the whole development of this dialogue, in which Socrates brings his hearers to behold the eternal in human personality. The hearers accept his thoughts, and they look into themselves to see if they can find in their inner experiences something which assents to his ideas. They make the objections which strike them. What has happened to the hearers when the dialogue is finished? They have found something within them which they did not possess before. They have not merely accepted an abstract truth, but they have gone through a development. Something has come to life in them which was not living in them before. Is not this to be compared with an initiation? And does not this throw light on the reason for Plato's setting forth his philosophy in the form of conversation? These dialogues are nothing else than the literary form of the events which took place in the sanctuaries of the Mysteries. We are convinced of this from what Plato himself says in many passages. Plato wished to be, as a philosophical teacher, what the initiator into the Mysteries was, as far as this was compatible with the philosophical manner of communication. It is evident how Plato feels himself in harmony with the Mysteries! He only thinks he is on the right path when it is taking him where the Mystic is to be led. He thus expresses himself on the subject in the Timæus. "All those who are of right mind invoke the gods for their small or great enterprises; but we who are engaged in teaching about the universe,—how far it is created and uncreated,—have the special duty, if we have not quite lost our way, to call upon and implore the gods and goddesses that we may teach everything first in conformity with their spirit, and next in harmony with ourselves." And Plato promises those who follow this path, that divinity, as a deliverer, will grant them illuminating teaching as the conclusion of their devious and wandering researches.
It is especially the Timæus that reveals to us how the Platonic cosmogony is connected with the Mysteries. At the very beginning of this dialogue there is mention of an initiation. Solon is initiated by an Egyptian priest into the formation of the worlds, and the way in which eternal truths are symbolically expressed in traditional myths. "There have already been many and various destructions of part of the human race," says the Egyptian priest to Solon, "and there will be more in the future; the most extensive by fire and water, other lesser ones through countless other causes. It is also related in your country that Phaëthon, the son of Helios, once mounted his father's chariot, and as he did not know how to drive it, everything on the earth was burnt up, and he himself slain by lightning. This sounds like a fable, but it contains the truth of the change in the movements of the celestial bodies revolving round the earth and of the annihilation of everything on the earth by much fire. This annihilation happens periodically, after the lapse of certain long periods of time." This passage in the Timæus contains a plain indication of the attitude of the initiate towards folk-myths. He recognises the truths hidden in their images.
The drama of the formation of the world is brought before us in the Timæus. Any one who will follow up the traces which lead to this formation of the cosmos arrives at a dim apprehension of the primordial force from which all things proceeded. "Now it is difficult to find the Creator and Father of the universe, and when we have found Him, it is impossible to speak about Him so that all may understand." The Mystic knew what this "impossibility" means. It points to the divine drama. God is not present in what belongs merely to the senses and understanding. In those He is only present as nature. He is under a spell in nature. Only one who awakens the divine within himself is able to approach Him. Thus He cannot at once be made comprehensible to all. But even to one who approaches Him, He does not appear Himself. The Timæus says that also. The Father made the universe out of the body and soul of the world. He mixed together, in harmony and perfect proportions, the elements which came into being when He, pouring Himself out, gave up His separate existence. Thereby the body of the world came into being, and stretched upon it, in the form of a cross, is the soul of the world. It is what is divine in the world. It found the death of the cross so that the world might come into existence. Plato may therefore call nature the tomb of the divine, a grave, however, in which nothing dead lies but the eternal, to which death only gives the opportunity of bringing into expression the omnipotence of life. And man sees nature in the right light when he approaches it in order to release the crucified soul of the world. It must rise again from its death, from its spell. Where can it come to life again? Only in the soul of initiated man. Then wisdom finds its right relation to the cosmos. The resurrection, the liberation of God, that is wisdom. In the Timæus the development of the world is traced from the imperfect to the perfect. An ascending process is represented imaginatively. Beings are developed. God reveals Himself in their development. Evolution is the resurrection of God from the tomb. Within evolution, man appears. Plato shows that in man there is something special. It is true the whole world is divine, and man is not more divine than other beings. But in other beings God is present in a hidden way, in man he is manifest. At the end of the Timæus we read: "And now we might assert that our study of the universe has attained its end, for after the world was provided and filled with mortal and immortal living beings, it, this one and only begotten world, has itself become a visible being embracing everything visible, and an image of the Creator. It has become the God perceptible to the senses, and the greatest and best world, the fairest and most perfect which there could be." But this one and only begotten world would not be perfect if the image of its Creator were not to be found amongst the images it contains. This image can only be engendered in the human soul. Not the Father Himself, but the Son, God's offspring, living in the soul, and being like unto the Father, him man can bring forth.
Philo, of whom it was said that he was the resurrected Plato, characterised as the "Son of God" the wisdom born out of man, which lives in the soul and contains the reason existing in the world. This cosmic reason, or Logos, appears as the book in which "everything in the world is recorded and delineated." It also appears as the Son of God, "following in the paths of the Father, and creating forms, looking at their archetypes." The platonising Philo addresses this Logos as Christ, "As God is the first and only king of the universe, the way to Him is rightly called the 'Royal Road.' Consider this road to be philosophy ... the road which the company of the ancient ascetics took, who turned away from the entangling fascination of pleasure and devoted themselves to the noble and earnest cultivation of the beautiful. The law names this Royal Road, which we call true philosophy, God's word and spirit."
It is like an initiation to Philo when he enters upon this path, in order to meet the Logos who, to him, is the Son of God. "I do not shrink from relating what has happened to me innumerable times. Often when I wished to put my philosophical thoughts in writing, in my accustomed way, and saw quite clearly what was to be set down, I nevertheless found my mind barren and rigid, so that I was obliged to desist without having accomplished anything, and seemed to be hampered with idle fancies. At the same time I could not but marvel at the power of the reality of thought, with which it rests to open and to close the womb of the human soul. Another time, however, I would begin empty and arrive, without any trouble, at fulness. Thoughts came flying like snowflakes or grains of corn invisibly from above, and it was as though divine power took hold of me and inspired me, so that I did not know where I was, who was with me, who I was, or what I was saying or writing; for just then the flow of ideas was given me, a delightful clearness, keen insight, and lucid mastery of material, as if the inner eye were able to see everything with the greatest distinctness."
This is a description of a path to knowledge so expressed that we see that any one taking this path is conscious of flowing in one current with the divine, when the Logos becomes alive within him. This is also expressed clearly in the words: "When the spirit, moved by love, takes its flight into the most holy, soaring joyously on divine wings, it forgets everything else and itself. It only clings to and is filled with that of which it is the satellite and servant, and to this it offers the incense of the most sacred and chaste virtue."
