But before the appreciator can have brought himself to the point of perception where he is able to respond directly to the significance of art and to make the artist's emotion a part of his own emotional experience, he must needs have traveled a long and rather devious way. Appreciation is not limited to the exercise of the intellect, as in the recognition of the subject of a work of art and in the interest which the technically minded spectator takes in the artist's skill. It does not end with the gratification of the senses, as with the delight in harmonious color and rhythmic line and ordered mass. Yet the intellect and the senses, though they are finally but the channel through which the artist's meaning flows to reach and rouse the feelings, nevertheless play their part in appreciation. Between the spirit of the artist and the spirit of the appreciator stands the individual work of art as the means of expression and communication. In the work itself emotion is embodied in material form. The material which art employs for expression constitutes its language. Certain principles govern the composition of the work, certain processes are involved in the making of it, and the result possesses certain qualities and powers. The processes which enter into the actual fashioning of the work are both intellectual and physical, requiring the exercise of the artist's mind in the planning of the work and in the directing of his hand; so far as the appreciator concerns himself with them, they address themselves to his intellect. The finished work in its material aspect possesses qualities which are perceived by the senses and which have a power of sensuous delight. Upon these processes and these qualities depends in part the total character of a work of art, and they must be reckoned with in appreciation. In his approach to any work of art, therefore, the layman is confronted first of all with the problem of the language which the work employs. Architecture uses as its language the structural capabilities of its material, as wood or stone, bringing all together into coherent and serviceable form. Poetry is phrased in words. Painting employs as its medium color and line and mass. At the outset, in the case of any art, we have some knowledge of the signification of its terms. Here is a painting of a sower. Out of previous experience of the world we easily recognize the subject of the picture. But whence comes the majesty of this rude peasant, the dignity august of this rough and toil-burdened laborer, his power to move us? In addition to the common signification of its terms, then, language seems to have a further expressiveness, a new meaning imparted to it by the way in which the artist uses it. In a poem we know the meaning of the words, but the _poetry_ of it, which we feel rather than know, is the creation of the poet, wrought out of the familiar words by his cunning manipulation of them.
