For the age was very busy with philological speculation; and many questions were beginning to be asked about language which were parallel to other questions about justice, virtue, knowledge, and were illustrated in a similar manner by the analogy of the arts. Was there a correctness in words, and were they given by nature or convention? In the presocratic philosophy mankind had been striving to attain an expression of their ideas, and now they were beginning to ask themselves whether the expression might not be distinguished from the idea? They were also seeking to distinguish the parts of speech and to enquire into the relation of subject and predicate. Grammar and logic were moving about somewhere in the depths of the human soul, but they were not yet awakened into consciousness and had not found names for themselves, or terms by which they might be expressed. Of these beginnings of the study of language we know little, and there necessarily arises an obscurity when the surroundings of such a work as the Cratylus are taken away. Moreover, in this, as in most of the dialogues of Plato, allowance has to be made for the character of Socrates. For the theory of language can only be propounded by him in a manner which is consistent with his own profession of ignorance. Hence his ridicule of the new school of etymology is interspersed with many declarations “that he knows nothing,” “that he has learned from Euthyphro,” and the like. Even the truest things which he says are depreciated by himself. He professes to be guessing, but the guesses of Plato are better than all the other theories of the ancients respecting language put together.
