In Republic VI 508e-9b Plato has Socrates claim that the Good is the cause (αίτίαν) of truth and knowledge as well as the very being of the Forms. Consequently, as causes must be distinct from and superior to their effects, the Good is neither truth nor knowledge nor even being, but exceeds them all in beauty (509a), as well as in honour and power (509b). No other passage in Plato has had a more intoxicating effect on its readers. To take (...) just one example, James Adam was moved to quote St. Paul when he remarked about this passage that, 'it is highly characteristic of Plato's whole attitude that he finds the true keystone of the Universe — the ultimate fountain from which both Knowledge and Existence flow — in no cold and colourless ontological abstraction, like Being, but in that for which "all creation groans and labours".
