There are in our minds in solution a vast number of emotional attitudes, feelings ready to be re-excited when the proper stimulus arrives, and more than anything else it is these forms, this residue of experience, which, fuller and richer than in the mind if the ordinary man, constitute the artist's capital. What is called the magic of the artist resides in his ability to transfer these values from one field of experience to another, to attach them to objects of our common life, and by his imaginative insight make these objects poignant and momentous. Not colors, not sense qualities as such, are either matter or form, but these qualities as thoroughly imbued, impregnated, with transferred value. And then they are either matter or form according to the direction of our interest.
