There are no means of determining the relative order in time of the Phaedrus, Symposium, Phaedo.
In "Phaedo," Plato describes the soul, and explains its immortality.
For in the Phaedo the earth is described as the centre of the world, and is not said to be in motion.
The argument, as in the Phaedo and Gorgias, is supplemented by the vision of a future life.
The myth of the Phaedo is of the same type, but it is more cosmological, and also more poetical.
And yet Simmias is not really great and also small, but only when compared to Phaedo and Socrates.
In the Phaedo the main argument up to which all the others lead is that the soul participates in the idea of life.
Two arguments of this ethical character occur in the Phaedo.
The idealism of Plato is here presented in a less developed form than in the Phaedo and Phaedrus.
The Symposium may be observed to resemble as well as to differ from the Phaedo.
