Discussion of Plato's Cratylus, to which this book is a notable contribution, must straightway come to terms with the question of Plato's seriousness (or lack thereof) in the etymology sections of the dialogue. Professor Sedley is a strong advocate of the seriousness of the etymologies, a position which, he remarks, will not surprise most classicists, although it "may cause apoplexy among many of Plato's philosophical admirers" (23). More colloquially he writes, "if Plato was joking, the joke flopped" (39).

But need we assume that Plato was either serious or joking? His sense of humor was peculiar, and seems to me nicely characterized by Guthrie when, in commenting on the present dialogue, he speaks of Plato as "tumbling together with an equally straight face absurdities and deeply held convictions" (History V, 25). I also incline more than Sedley to the frequent topicality of Plato's work.

Nevertheless, the Sedley thesis may be seen to pay rich rewards. Perhaps most notable is the perception that the etymologies constitute a philosophical curriculum, moving along a well-defined trace from cosmology to the consideration (a watershed here) of ethical terms. This progression is especially significant in marking the emancipation of Plato from his early association with Cratylus and his subsequent allegiance to Socrates.

Another mandatory topic is, of course, chronology. The Cratylus is seen to be unusual here in that what we have is most probably a reedited version. (A substantive point is at issue because the earlier version fails to distinguish clearly between the lawmaker and the [End Page 490] dialectician.) Thus to the question, where does the Cratylus fit in the traditional chronology, Sedley's answer is, "not in any one place" (7). As to the projected time of the revision, proximity to the Sophist is most likely.

Sedley's general approach to the etymologies is hierarchical (here he identifies two important principles, Uniformity and Groundedness) rather than one of mutual support. He writes that the "'imitation' relation between sounds and things will be found [at] not just the primary level, but all the way up the chain" (126). Similarly with Socrates' painting analogy: "the primary pigments which the painter uses already imitate the simplest objects of vision" (128). In both cases the principles of Uniformity and Groundedness "are to some extent permitted to merge" (127).

The business of name-making is of course a techne, as is that of painting. That both of these arts are approximate in nature is not an "ad hoc postulate [but] lies at the heart of Platonic metaphysics," since "any craftsman's embodiment of a Form in matter is necessarily less than perfect" (45). (As Sedley tellingly points out, "it is the Sophist Thrasymachus, and not Socrates, who proposes that a craftsman, qua craftsman, never gets anything wrong" [44].) As for Socrates' final position, it is "not the reversion to conventionalism that it has so often been taken to be" (145). Convention does play some part in signification, but it is also the case that names are some kind of vocal imitations, "a thesis, massively documented in the etymological section, from which Socrates never retreats" (145).

One point on which I would like to have had Sedley's comments is the following: what does he think of Diogenes Laertius's remark (III, 6) that not only did Plato, after the death of Socrates, "attach himself to Cratylus the Heraclitean," but also to Hermogenes "who professed the philosophy of Parmenides"? Now the only real Parmenideanism in the dialogue (the position that a name is either a true name or not a name at all) is attributed not to Hermogenes but to Cratylus! (Is Descartes an empiricist? Is Hume a rationalist?) Furthermore, even though Cratylus adopts this position on a variety of occasions (429d, 432a, 433c, 436c, and 438c), he is too flighty (or, one might say, too fluxy) to stick with it, and continually relapses (431a, 432d, 433b, 435e, for instance). At the risk of being categorized as a non-serious reader of the Cratylus (which I am not...
