I am pleased to have been able to vindicate Plato from the oft-rehearsed charge of not having distinguished relations from qualities. Not only does Phaedo 102B7-C4 show quite clearly that he did make the proper distinction, but the theory of relations he adumbrated there is logically sound and ontologically viable. Furthermore, it is refreshing to think of relations not as Forms or universals, but as chains of ontologically tied universals.Naturally, now that we have a clear understanding of Plato's Phaedo theory (...) of relations and relational facts there is plenty of work to do. We must examine the other dialogues for alterations or even preservation of that theory. Moreover, there are those arguments of Aristotle that purport to reduce Plato's Theory of Forms to absurdity on account of relations. But of this I shall say more at some other time. (shrink)

This book contains a collection of essays written by Castaeda. With the exception of the previously unpublished chapter 7, the essays were originally published in German, Austrian, and American journals and books in the time period from 1966 to 1990. They explore, with often very detailed arguments, the nature of the I and the structure of consciousness.

Although the proper formulation and assessment of Ludwig Wittgenstein's argument (or arguments) against the possibility of a private language continues to be disputed, the issue has lost none of its urgency. At stake is a broadly Cartesian conception of experiences that is found today in much philosophy of mind.
