For man is a symbol-making animal. He constructs a symbolic model of outer reality in his brain, and expresses it by a second set of symbols in terms of words, equations, pigment, or stone. All he knows directly are bodily sensations, and all he can directly do is to perform bodily motions; the rest of his knowledge and means of expression is symbolical. To use a phrase coined by J. Cohen, man has a metaphorical consciousness. Any attempt to get a direct grasp at naked reality is self-defeating; Urania, too, like the other muses, always has a last veil left to fold in.
