Art is not, as the metaphysicians say, the manifestation of some mysterious Idea of beauty, or God; it is not, as the æsthetical physiologists say, a game in which man lets off his excess of stored-up energy; it is not the expression of man’s emotions by external signs; it is not the production of pleasing objects; and, above all, it is not pleasure; but it is a means of union among men, joining them together in the same feelings, and indispensable for the life and progress towards well-being of individuals and of humanity. As, thanks to man’s capacity to express thoughts by words, every man may know all that has been done for him in the realms of thought by all humanity before his day, and can, in the present, thanks to this capacity to understand the thoughts of others, become a sharer in their activity, and can himself hand on to his contemporaries and descendants the thoughts he has assimilated from others, as well as those which have arisen within himself; so, thanks to man’s capacity to be infected with the feelings of others by means of art, all that is being lived through by his contemporaries is accessible to him, as well as the feelings experienced by men thousands of years ago, and he has also the possibility of transmitting his own feelings to others. If people lacked this capacity to receive the thoughts conceived by the men who preceded them, and to pass on to others their own thoughts, men would be like wild beasts, or like Kaspar Hauser.[60] And if men lacked this other capacity of being infected by art, people might be almost more savage still, and, above all, more separated from, and more hostile to, one another. And therefore the activity of art is a most important one, as important as the activity of speech itself, and as generally diffused. We are accustomed to understand art to be only what we hear and see in theatres, concerts, and exhibitions; together with buildings, statues, poems, novels.... But all this is but the smallest part of the art by which we communicate with each other in life. All human life is filled with works of art of every kind—from cradle-song, jest, mimicry, the ornamentation of houses, dress and utensils, up to church services, buildings, monuments, and triumphal processions. It is all artistic activity. So that by art, in the limited sense of the word, we do not mean all human activity transmitting feelings, but only that part which we for some reason select from it and to which we attach special importance. This special importance has always been given by all men to that part of this activity which transmits feelings flowing from their religious perception, and this small part of art they have specifically called art, attaching to it the full meaning of the word.
