reflection we see the second world, and the second world always remains to the mind rendered in form and given in relations by the mind's constructive faculties. While, therefore, the physical world as a simple, uncomprehended fact goes before each finite mind, awakening that mind to activity, the actual and partially comprehensible world in which each mind moves is built up under its own perceptions, and harmonized by its own ideas.

Perceptions as of taste, odor, sound and color, with which we habilitate the frame-work of matter, have in them a purely subjective element. Sound is not in the air, but in the ear that hears; color is not spread as a tent in the sky, nor as a covering over the plain; it is a transfiguration, by the mind, through the medium of an organic sensibility, of facts in themselves quite unapproachable.
