From this last type of imagery we may proceed without a break to the consideration of _simile._ For in the image we already find the initial appearance of the independent and imageless expression of this significance, the subject of the image being here designated. The two types are, however, distinguished by this that in the simile everything which exclusively manifests the image in a figurative form is furthermore able to receive an independently subsistent mode of expression as significance, which thereby appears alongside of its image and is placed in comparison with the same. The metaphor and image declare the significances without making that declaration explicit, so that it is only the context, in which either metaphor or image occur, which shows without disguise what their meaning veritably is intended to be. In the simile, on the contrary, both aspects, image and significance, albeit no doubt we find at one time it is the image, and at another the significance which is most clearly and fully emphasized, are kept completely apart and set forth each in its isolation, and only then, and in such severation are related to one another in virtue of the similarity of their content.
Viewed in this relation it is possible to characterize the simile as to some extent merely a vain _repetition_, in so far, that is, as one and the same content is reproduced in a twofold, or it may be threefold or fourfold form. In part, too, we may even see in it a frequently wearisome _superfluity_, for the reason that the significance is already there as an independent factor, and requires no further mode of figuration to render it intelligible. The question consequently presses upon us here with even more insistence than in the case of the image and metaphor, what essential interest and object there may be in the employment of isolated examples or a whole number of similes. For their use is not to be justified on the commonly received ground of mere vivacity, and the contention that they increase the lucidity of expression will assist us just as little. On the contrary similes make a poem only too frequently insipid and overweighted, and an image or metaphor by itself can possess a clarity fully as pronounced without there being any previous necessity to attach the significance to either as something still outside.
