Str. As the result of all this, we must not say either that the universe turns itself always, or that it is always turned by God in two opposite courses, or again that two divinities opposed to one another turn it. The only remaining alternative is what I suggested a little while ago, that the universe is guided at one time by an extrinsic divine cause, acquiring the power of living again and receiving renewed immortality from the Creator, and at another time it is left to itself and then moves by its own motion, being left to itself at such a moment that it moves backwards through countless ages, because it is immensely large and most evenly balanced, and turns upon the smallest pivot.
Y. Soc. All that account of yours appears, at any rate, very reasonable.
Str. Then, in the light of what has been said, let us consider and gain understanding of the event which we said was the cause of all those wonderful portents; for it is really just this.
Y. Soc. Just what?
Str. The fact that at certain periods the universe has its present circular motion, and at other periods it revolves in the reverse direction.
Y. Soc. How was this the cause?
Str. We cannot help believing that of all the changes which take place in the heavens this reversal is the greatest and most complete.
Y. Soc. It certainly seems to be so.
Str. Therefore we must also believe that at the same time the greatest changes come upon us who dwell within the heavens.
Y. Soc. That is likely too.
Str. And animals cannot well endure many great and various changes at once. That is a familiar fact, is it not?
Y. Soc. Of course.
Str. Inevitably, then, there is at that time great destruction of animals in general, and only a small part of the human race survives; and the survivors have many experiences wonderful and strange, the greatest of which, a consequence of the reversal of everything at the time when the world begins to turn in the direction opposed to that of its present revolution, is this. Footnote 1The tale of Atreus introduces the fanciful theory of the reversal of the revolution of the heavenly bodies, and this, especially in an age when the stars were believed to exercise a direct influence upon mankind and other creatures, naturally brings with it the reversal of all processes of growth. This leads to a new birth of mankind, and the Stranger then briefly describes the age of innocence, the fall of man and the barbarism that follows, and the partial restoration of man through divine interposition and the gift of the various arts of civilization. Plato does not offer this as a real explanation of the existing condition of the world, but it serves, like the myths introduced in other dialogues to present, in connection with accepted mythology, a theory which may account for some of the facts of life.
Y. Soc. What is that experience?
Str. First the age of all animals, whatever it was at the moment, stood still, and every mortal creature stopped growing older in appearance and then reversed its growth and became, as it were, younger and more tender; the hoary locks of the old men grew dark, and bearded cheeks grew smooth again as their possessors reverted to their earlier ages, and the bodies of young men grew smoother and smaller day by day and night by night, until they became as new-born babes, to which they were likened in mind and body; and then at last they wasted away entirely and wholly disappeared. And the bodies of those who died by violence in those times quickly underwent the same changes, were destroyed, and disappeared in a few days.
