The beautiful, then, is not subject to the intellect. We cannot demonstrate or coldly discover it; we cannot weigh or measure it. Further to illustrate this position: we do not see with our outward eye any more than we do with spectacles. The apparent ocular apparatus is but the passive, unconscious instrument to transmit images thrown through it upon a fine interior fibre, the optic nerve; and even this does not take cognizance of the object, but is only another conductor, carrying the image still farther inward, to the intellectual nerves of the brain; and not until it reaches them do we see the object, not until then is its individuality and are its various physical qualities, size, shape, etc., apprehended. And now the intellect itself becomes a conductor, transmitting still deeper inward to the seat of emotion the image of the object; and not until it reaches that depth is its beauty recognized. In all her structures and arrangements Nature is definite, precise, and economical. In subdivision of labor she is minute and absolute, providing for every duty its special exclusive agent. In the mind there is as severe a sundering of functions as in the body, and the intellect can no more encroach upon or act for the mental sensibilities than the stomach can at need perform the office of the heart, or the liver that of the lungs. True, no ripe results in the higher provinces of human life can be without intimate alliance between the mental sensibilities and the intellect; nevertheless they are in essence as distinct from one another as are the solar heat and the moisture of the earth, without whose constant cooeperation no grain or fruit or flower can sprout or ripen.
