- This is certainly what I think Kant was getting at in the Critique of
- Pure Reason, when he discussed noumena. Also, it seems consistent with
- his saying (I don't remember where right now) that he set limits on
- reason to make room for God.
-
- However, I think that it's a bit hard on old Plato to say that the
- Republic and the Timeus represent the acme of his thought. In Phaedo,
- probably his greatest work, he paints a far different picture in which
- the search for truth is described metaphorically as sinking pilings
- into mud to support an edifice. You sink the piling so deep and it
- will support the edifice you want to erect. If later you want to add
- to the edifice and the pilings won't support the added weight, you
- have to sink new pilings deeper into the ground. However, at the end
- Socrates dies without ever having hit bedrock.
-
- In contrast to the sad and restrained tone of Phaedo, the Republic
- seems a bit of a party game---a parody of the torch race that precedes
- the dialogue.
