Religion and art were then united potentially in the original art impulse just as the strength and lofty beauty of the oak were latent in the acorn. The art impulse is natural to man; it is intellectual. It requires brains to be artistic, as it requires brains to laugh, and no animal has done either or will ever do either. The bird in building its nest displays an intelligence not its own; its nest building is inherited just as its song is. Jean Fabre’s observations have shown conclusively the wonders of instinct, coupled with the stupidity of the creature possessing the instinct. But the earliest scrawl or daub of the child displays the mind working on matter and the deliberate shaping of means to an end. All intellectual testers from Simon-Binet to the latest have found the making or interpreting of pictures a measure of intellectual power. They are right. Art is rationalized pigments or sounds or words with their images or some other rationalized material. Dr. James Harvey Robinson in _Mind in the Making_ says that we are wrong in rationalizing the past to make up our minds, and how does he show it? By rationalizing another past for us. The truth is we must rationalize the past, and Dr. Robinson should induce us, not to stop rationalizing, but to rationalize correctly and should give us something better than universal skepticism with which to rationalize. The art tendency is one with the religious tendency in being rational and intellectual. Art and religion strive for high ideals; they are disinterested and unselfish. LaFarge says to Saint Gaudens: “That work is not worthy of you,” and Saint Gaudens picks up a hammer and smashes the sculpture. That is an instance paralleling the heroic following of religious ideals with like sacrifices. Was it fear of bogies or love of their dead which filled so many tombs with precious articles? Believing in immortality, Egyptians and Myceneans gave to the dead what was most precious, and what was most precious was the finest art in the costliest material. Love keeps graves green: fear erects a crematory. Art and religion are personal and emotional. Each has its own proper expression. Of religion the expression is worship and of art it is concrete embodiment of the ideal, and in both cases the expression is intimately personal and permeated with feeling. Art is more sensible and so more emotional because its expression must be presented to the senses or at least to the imagination. Religion whose primary expression is an act of the will, need not of its nature be attended with emotion or external display but it usually is, and feeling and expression commonly help to the fuller expression of religion. The rapture of art and the ecstasy of religion, though differing in much, have also much in common.
