Dialogues of Plato - MobileReference [663]
Returning to Plato, we may observe that a similar mixture of truth and error appears in other parts of the argument. He is aware of the absurdity of mankind framing their whole lives according to Homer; just as in the Phaedrus he intimates the absurdity of interpreting mythology upon rational principles; both these were the modern tendencies of his own age, which he deservedly ridicules. On the other hand, his argument that Homer, if he had been able to teach mankind anything worth knowing, would not have been allowed by them to go about begging as a rhapsodist, is both false and contrary to the spirit of Plato (Rep.). It may be compared with those other paradoxes of the Gorgias, that 'No statesman was ever unjustly put to death by the city of which he was the head'; and that 'No Sophist was ever defrauded by his pupils' (Gorg.)...
The argument for immortality seems to rest on the absolute dualism of soul and body. Admitting the existence of the soul, we know of no force which is able to put an end to her. Vice is her own proper evil; and if she cannot be destroyed by that, she cannot be destroyed by any other. Yet Plato has acknowledged that the soul may be so overgrown by the incrustations of earth as to lose her original form; and in the Timaeus he recognizes more strongly than in the Republic the influence which the body has over the mind, denying even the voluntariness of human actions, on the ground that they proceed from physical states (Tim.). In the Republic, as elsewhere, he wavers between the original soul which has to be restored, and the character which is developed by training and education...
The vision of another world is ascribed to Er, the son of Armenius, who is said by Clement of Alexandria to have been Zoroaster. The tale has certainly an oriental character, and may be compared with the pilgrimages of the soul in the Zend Avesta (Haug, Avesta). But no trace of acquaintance with Zoroaster is found elsewhere in Plato's writings, and there is no reason for giving him the name of Er the Pamphylian. The philosophy of Heracleitus cannot be shown to be borrowed from Zoroaster, and still less the myths of Plato.
The local arrangement of the vision is less distinct than that of the Phaedrus and Phaedo. Astronomy is mingled with symbolism and mythology; the great sphere of heaven is represented under the symbol of a cylinder or box, containing the seven orbits of the planets and the fixed stars; this is suspended from an axis or spindle which turns on the knees of Necessity; the revolutions of the seven orbits contained in the cylinder are guided by the fates, and their harmonious motion produces the music of the spheres. Through the innermost or eighth of these, which is the moon, is passed the spindle; but it is doubtful whether this is the continuation of the column of light, from which the pilgrims contemplate the heavens; the words of Plato imply that they are connected, but not the same. The column itself is clearly not of adamant. The spindle (which is of adamant) is fastened to the ends of the chains which extend to the middle of the column of light--this column is said to hold together the heaven; but whether it hangs from the spindle, or is at right angles to it, is not explained. The cylinder containing the orbits of the stars is almost as much a symbol as the figure of Necessity turning the spindle;--for the outermost rim is the sphere of the fixed stars, and nothing is said about the intervals of space which divide the paths of the stars in the heavens. The description is both a picture and an orrery, and therefore is necessarily inconsistent with itself. The column of light is not the Milky Way--which is neither straight, nor like a rainbow--but the imaginary axis of the earth. This is compared to the rainbow in respect not of form but of colour, and not to
