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 most useful man in the most useful world, so long as only commodity was served, would remain unsatisfied. But, as fast as he sees beauty, life acquires a very high value.
Ralph Waldo Emerson
