(5) In addition to these anticipations of the general principles of philology, we may note also a few curious observations on words and sounds. “The Eretrians say sklerotes for skleroter;” “the Thessalians call Apollo Amlos;” “The Phrygians have the words pur, udor, kunes slightly changed;” “there is an old Homeric word emesato, meaning ‘he contrived’;” “our forefathers, and especially the women, who are most conservative of the ancient language, loved the letters iota and delta; but now iota is changed into eta and epsilon, and delta into zeta; this is supposed to increase the grandeur of the sound.” Plato was very willing to use inductive arguments, so far as they were within his reach; but he would also have assigned a large influence to chance. Nor indeed is induction applicable to philology in the same degree as to most of the physical sciences. For after we have pushed our researches to the furthest point, in language as in all the other creations of the human mind, there will always remain an element of exception or accident or free-will, which cannot be eliminated. The question, “whether falsehood is impossible,” which Socrates characteristically sets aside as too subtle for an old man (compare Euthyd.), could only have arisen in an age of imperfect consciousness, which had not yet learned to distinguish words from things. Socrates replies in effect that words have an independent existence; thus anticipating the solution of the mediaeval controversy of Nominalism and Realism. He is aware too that languages exist in various degrees of perfection, and that the analysis of them can only be carried to a certain point. “If we could always, or almost always, use likenesses, which are the appropriate expressions, that would be the most perfect state of language.” These words suggest a question of deeper interest than the origin of language; viz. what is the ideal of language, how far by any correction of their usages existing languages might become clearer and more expressive than they are, more poetical, and also more logical; or whether they are now finally fixed and have received their last impress from time and authority. On the whole, the Cratylus seems to contain deeper truths about language than any other ancient writing. But feeling the uncertain ground upon which he is walking, and partly in order to preserve the character of Socrates, Plato envelopes the whole subject in a robe of fancy, and allows his principles to drop out as if by accident.
