It must be a natural attraction for the insoluble mysteries of life that has induced so many philosophers during the last two centuries to put forward æsthetic systems. That no two of these systems agree on important points, and that each and every one has crumbled to dust from a touch of the wand of experience administered by a hundred hands, are well-known facts, yet still the systems continue to be calmly presented as if they were valuable contributions to knowledge. Each new critic in the domain of philosophy carefully and gravely sets them up, and then carefully and gravely knocks them down.[3] An excuse for the systems has been here and there offered, that the explanations thereof sometimes include valuable philosophical comments or suggestions. This may be, but students cannot reasonably be expected to sift out a few oats from a bushel of husks, even if the supply be from the bin of a Hegel or a Schopenhauer. Is it too much to suggest that these phantom systems be finally consigned to the grave of oblivion which has yawned for them so long and so conspicuously? Bubbles have certain measurements and may brilliantly glow, but they are still bubbles. It is as impossible to build up a system of philosophy upon the perception of beauty, which depends entirely upon physical and physiological laws, as to erect a system of ethics on the law of gravitation, for a feasible connection between superstructure and foundation cannot be presented to the mind. We may further note that a proper apprehension of standards of judgment in art cannot be obtained unless the separate and relative æsthetic values of the two forms of beauty are considered, because the beauty of a work may appear greater at one time than at another, according as it is more or less permanent or fleeting, that is to say, according as the balance of the sensorial and intellectual elements therein is more or less uneven; or if the beauty present be almost entirely emotional, according as the observer may be affected by independent sensorial conditions of time or place. Consequent upon these considerations, an endeavour has been made in this work to distinguish between the two forms of beauty in the various arts, and the separate grades thereof. It will be noticed that the writer has adopted the somewhat unusual course of including fiction among the fine arts. Why this practice is not commonly followed is hard to determine, but no definition of a fine art has been or can be given which does not cover fiction. In the definition here accepted, the art is clearly included, for the primary object of fiction is the beautiful representation of nature for the purpose of giving disinterested pleasure. * * * * *
