But the Ego now turns back, not only upon itself, but also upon former Philosophies and wheels them into line with its own process.

The Being of the Ego is to be not simply self-con scious within itself or subjectively, but it has to return and take up Pure or Immediate Being (Greek), and God s Being (Medieval) into its movement.

Thus we see that Descartes is a re turn to the very beginning of Philosophy in or der to bring its total sweep into the new advance.

In this sense we observe that Descartes still be longs to the Kenascence, going back, indeed, to ancient thought but integrating it vitally with the modern.

Accordingly we shall have to look at this met aphysical stage of Descartes Philosophy under three heads: the Ego s knowing itself as exist ent, the Ego s knowing God as existent, the Ego s knowing the world (objective) as existent.
