Natural and zesthetio stimuli. — Art, which is merely an external stimulus, can be com municated to the brain only through the senses. It differs from other stimuli only in degree of perfection — that is, it has been arranged in such a manner that it produces a complete and satis fying reaction. But the inward activity of art, through the sense media, follows the same physi cal laws as does a natural stimulus. Only in the completeness of the impression does it distinguish itself from other stimuli. Once this fact is real ised, the determining of msthetic reactions will cease to be looked upon as an impossibility.
