This chapter studies Plato’s Phaedo. In the Phaedo, the afterlife journey and the synoptic vision of the universe are collapsed into one another. In the myth of the dialogue, we are all, all the time, said to be on an underworld journey, since we live in the “creases” of the earth, not on its surface. At the same time, the True Earth of the Phaedo mirrors in its shape the spherical universe of the vision, as we also see it in the Spindle of Necessity in Plato’s Republic, and in the flight of souls around the universe in Plato’s Phaedrus. The Phaedo is a true geography of soul, in that the fate of the soul is integrated with the shape and motive forces of the earth seen as a whole. What we have in the Phaedo is a complete synthesis of the mythical underworld with the “geographic” earth. Tartarus (Phaedo 111e7–112e3) is the lowest point of the world, but it is also the center of the sphere. The result of Plato’s assimilation of the underworld, the landscape of the soul, with the “scientific” earth, is that earth and soul become analogous. They can be studied in the same way. In the ideal world, the universe itself is our eschatology.
