Consciousness itself must be added to this list. For whatever arguments may be used in the realm of thought, when the moment of choice arrives in the realm of action, we are always conscious of the will as free. If the reason is justified in regarding the freedom of the will as an illusion, we are justified in denying the existence of the will altogether. For a will with only an illusion of freedom is not a will at all. In that ease it were better to eliminate the will and regard the soul as a thing which acts and reacts under the stimuli of motives like a helpless automaton endowed with consciousness. But the wiser course is to experiment with the will and let it prove its freedom to the sceptical reason by helping that same reason to retire into its proper place and associate itself with the apex-thought of the complex vision. Leaving the will then, as a thing limited and yet free, let us pass to a consideration of what I call "taste." This is the aesthetic sense, an original activity of the human soul, associated with that universal tendency in life and nature which we name the beautiful. I use the word "taste" at this moment in preference to "aesthetic sense," because I feel that this particular original activity of the complex vision has a wider field than is commonly supposed. I regard it, in fact, as including much more than the mere sense of beauty. I regard it as a direct organ of research, comparable to instinct or intuition, but covering a different ground. I regard it as a mysterious clairvoyance of the soul, capable of discriminating between certain everlasting opposites, which together make up an eternal duality in the very depths of existence. These opposites imply larger and more complicated issues than are implied in the words beautiful and ugly. The real and the unreal, the interesting and the uninteresting, the significant and the insignificant, the suggestive and the meaningless, the arresting and the commonplace, the exciting and the dull, the organic and the affected, the dramatic and the undramatic, are only some of the differences implied. The fact that art is constantly using what we call the ugly as well as what we call the commonplace, and turning both these into new forms of beauty, is a fact that considerably complicates the situation. And what art, the culminating creative energy of the aesthetic sense, can do, the aesthetic sense itself can do with its critical and receptive power.
