On the other hand, we must not venture to assert that the quality of interest is not to be found in masterpieces of literature. We have it in Schiller's dramas in an appreciable degree, and consequently they are popular; also in the _Oedipus Rex_ of Sophocles. Amongst masterpieces of description, we find it in Ariosto's _Orlando Furioso_; nay, an example of a high degree of interest, bound up with the beautiful, is afforded in an excellent novel by Walter Scott--_The Heart of Midlothian_. This is the most interesting work of fiction that I know, where all the effects due to interest, as I have given them generally in the preceding remarks, may be most clearly observed. At the same time it is a very beautiful romance throughout; it shows the most varied pictures of life, drawn with striking truth; and it exhibits highly different characters with great justice and fidelity. Interest, then, is certainly compatible with beauty. That was our third question. Nevertheless, a comparatively small admixture of the element of interest may well be found to be most advantageous as far as beauty is concerned; for beauty is and remains the end of art. Beauty is in twofold opposition with interest; firstly, because it lies in the perception of the idea, and such perception takes its object entirely out of the range of the forms enunciated by the principle of sufficient reason; whereas interest has its sphere mainly in circumstance, and it is out of this principle that the complexity of circumstance arises. Secondly, interest works by exciting the will; whereas beauty exists only for the pure perceptive intelligence, which has no will. However, with dramatic and descriptive literature an admixture of interest is necessary, just as a volatile and gaseous substance requires a material basis if it is to be preserved and transferred. The admixture is necessary, partly, indeed, because interest is itself created by the events which have to be devised in order to set the characters in motion; partly because our minds would be weary of watching scene after scene if they had no concern for us, or of passing from one significant picture to another if we were not drawn on by some secret thread. It is this that we call interest; it is the sympathy which the event in itself forces us to feel, and which, by riveting our attention, makes the mind obedient to the poet, and able to follow him into all the parts of his story.
