Herein is the explanation of the analogies, which exist in all the arts. They are the re-appearance of one mind, working in many materials to many temporary ends. Raphael paints wisdom, Handel sings it, Phidias carves it, Shakspeare writes it, Wren builds it, Columbus sails it, Luther preaches it, Washington arms it, Watt mechanizes it. Painting was called "silent poetry," and poetry "speaking painting." The laws of each art are convertible into the laws of every other.
Ralph Waldo EmersonThe growth of the intellect is spontaneous in every expansion. The mind that grows could not predict the times, the means, the mode of that spontaneity. God enters by a private door into every individual.
Ralph Waldo Emerson
