And we may here observe that it is not so much the _prosaic_ and _poetic_ style generally as the style of the _classic_ world in contrast with that of later periods which presents such a marked difference in the pre-eminent importance they attach to genuine or metaphorical expression respectively. It is not merely the Greek philosophers, such as Plato and Aristotle, or the great historians and orators, such as Thucydides and Demosthenes, but also the great poets, Homer and Sophocles, who, albeit we find examples of the simile in all them, remain on the whole, and without exception, constant in the use of their direct form of expression[95]. Their plastic severity and sterling substance will not permit them such a multifarious product, as is bound up with the use of metaphor, nor will it suffer them, even for the sake of gathering the so-called flowers of expression, to waver fitfully in devious ways from their ideal mintage of the completely simple and co-ordinate result as of one metal cast in one mould. The metaphor, in fact, is always an interruption to the logical course of conception and invariably to that extent a distraction, because it starts images and brings them together, which are not immediately connected with the subject and its significance, and for this reason tend to a like extent to divert the attention from the same to matter cognate with themselves, but strange to both. The prose of ancient writers in the extraordinary clarity and flexibility of its utterance and their poetry in the repose of its completely unfolded content[96], are equally removed from the frequent use of metaphor by modern writers.
On the other hand it is particularly in the East, and above all the later literature of Mohammedan poetry, which makes use of the indirect or figurative modes of expression, and, indeed, finds them essential. The same thing may be said, if less emphatically, of modern European literature. The diction of Shakespeare, for instance, is full of metaphor. The Spaniards, too, are very fond of this flowery region, and, indeed, have wandered off into it to the point of the most tasteless exaggeration and superfluity. Jean Paul falls under the same charge. Goethe by virtue of the equal strength and clarity of his vision to a less extent. Schiller, however, is even in his prose exceedingly rich both in image and metaphor; in his case this is rather due to his effort to bring really profound ideas within the range of the imaginative vision without being forced to expound all they imply for the mind in the technical language of philosophy. We behold and find there the essential unity of the speculative reason reflected on the mirror of Life as it stands before us.
