Phaedo.
Socrates, Cebes.have no concern : — If you please, then, we will proceed with the enquiry. Suppose we consider the question whether the souls of men after death are or are not in the world below. There comes into my mind an ancient doctrine which affirms that they go from hence into the other world, and returning hither, are born again from the dead.

Very true, replied Cebes. Then let us consider the whole 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 All things which have opposites are generated out of opposites.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 in all opposites there is of necessity a similar alternation ; I mean to say, for example, that anything which becomes greater must become greater after being less.
