The Cratylus begins with a paradox; it ends with a paradox; and it has a paradox in between. But this disturbing characteristic of the dialogue has been overshadowed, not to say ignored, in the literature. For commentators have seen it as their task to discover exactly what theory of language Plato himself, despite his declared perplexity, intends to adopt as he rejects the alternatives of Hermogenes and Cratylus. A common view, then, has been to suppose that the πορίαι of the (...) dialogue are mere camouflage for the hidden dogma, whatever that may be. A favoured candidate, of course, has been the theory of transcendent forms, in some preliminary version. As a consequence, the dialogue has often been seen as a precursor to the great metaphysical works of Plato's middle period such as the Phaedo or the Republic. Not so, I shall argue. My case is that this dialogue centres upon a series of paradoxes which are both powerful and unsettling. Their final effect is to attack the theory of forms, not to defend it. They are, I suggest, genuine proposals of philosophical difficulty, rather than mere artifice to disguise an idealist truth. As such, they belong, and may clearly be seen to belong, with works of the critical period which subject the theory of forms to scrutiny. Thus the πορίαι of the Cratylus have their counterparts in the Parmenides, the Theaetetus and the Sophist. I propose, then, that the dialogue was written during the late, critical period of Plato's philosophical activity. (shrink)

The article seeks to trace the image Plato has of Heraclitus and connect it with the argumentative structure of the Cratylus in order to understand the textual needs that give rise to the doctrine of perpetual flux, that is, the discussion regarding the correctness (ὀρθότης) of names. The inclusion of Heraclitus's testimony makes it possible to trace the alleged consolidation of the thesis regarding primary and secondary names as the axis of separation between two levels of reality (one stable, the other, changing) and the theory of Ideas -that is, as the basis of Plato's epistemology as set forth in the late dialogues-.

With the use of a particular metaphor, which appears at the end of the Cratylus and is taken up with perfect symmetry at the beginning of the Theaetetus, Plato certainly wanted to indicate the succession of Cratylus–Theaetetus as an order for reading the two dialogues, which Trasillus faithfully reproduced in structuring the second tetralogy of Platonic dialogues. The claim of the theory of ideas, with which the Cratylus ends, must therefore be considered the background in which to place not only (...) the analysis of the name carried out in the Cratylus, but also the discussion and criticism of the epistemological theories examined and refuted in the Theaetetus. The transition from the discussion of the name to that of the logos is another important theoretical element that connects the two dialogues. Another one is the theory of knowledge, already precisely elaborated in the Cratylus, and taken up and deepened in the Theaetetus. Finally, the theme of false and error is a third theoretical element common to the two dialogues, which, starting from Euthydemus, finds its solution in the Sophist. (shrink)
