It is characteristic of Plato and of his age to pass from the abstract to the concrete, from poetry to reality. Language is the expression of the seen, and also of the unseen, and moves in a region between them. A great writer knows how to strike both these chords, sometimes remaining within the sphere of the visible, and then again comprehending a wider range and soaring to the abstract and universal. Even in the same sentence he may employ both modes of speech not improperly or inharmoniously. It is useless to criticise the broken metaphors of Plato, if the effect of the whole is to create a picture not such as can be painted on canvas, but which is full of life and meaning to the reader. A poem may be contained in a word or two, which may call up not one but many latent images; or half reveal to us by a sudden flash the thoughts of many hearts. Often the rapid transition from one image to another is pleasing to us: on the other hand, any single figure of speech if too often repeated, or worked out too much at length, becomes prosy and monotonous. In theology and philosophy we necessarily include both 'the moral law within and the starry heaven above, ' and pass from one to the other (compare for examples Psalms xviii. and xix.). Whether such a use of language is puerile or noble depends upon the genius of the writer or speaker, and the familiarity of the associations employed. In the myths and parables of Plato the ease and grace of conversation is not forgotten: they are spoken, not written words, stories which are told to a living audience, and so well told that we are more than half-inclined to believe them (compare Phaedrus). As in conversation too, the striking image or figure of speech is not forgotten, but is quickly caught up, and alluded to again and again; as it would still be in our own day in a genial and sympathetic society. The descriptions of Plato have a greater life and reality than is to be found in any modern writing. This is due to their homeliness and simplicity. Plato can do with words just as he pleases; to him they are indeed 'more plastic than wax' (Republic). We are in the habit of opposing speech and writing, poetry and prose. But he has discovered a use of language in which they are united; which gives a fitting expression to the highest truths; and in which the trifles of courtesy and the familiarities of daily life are not overlooked
