real evidence that the living are only born from the dead; but if there is no evidence of this, then other arguments will have to be adduced.
That is very true, replied Cebes.
Then let us consider this question, not in relation to man only, but in relation to animals generally, and to plants, and to everything of which there is generation, and the proof will be easier. Are not all things which have opposites generated out of their opposites? I mean such things as good and evil, just and unjust—and there are innumerable other opposites which are generated out of opposites. And I want to show that this holds universally of all opposites;
I mean to say, for example, that anything which becomes greater must become greater after being less. True.
And that which becomes less must have been once greater and then become less. Yes.
And the weaker is generated from the stronger, and the swifter from the slower.
Very true.
And the worse is from the better, and the more just is from the more unjust?
Of course.
And is this true of all opposites? and are we convinced that all of them are generated out of opposites?
Yes.
And in this universal opposition of all things, are there not also two intermediate processes which are ever going on, from one to the other, and back again; where there is a greater and a less there is also an intermediate process of increase and diminution, and that which grows is said to wax, and that which decays to wane? Yes, he said.
And there are many other processes, such as division and composition, cooling and heating, which equally involve a passage into and out of one another. And this holds of all opposites, even though not always expressed in words—they are generated out of one another, and there is a passing or process from one to the other of them?
