What makes the man of the world-cities incapable of living on any but this artificial footing is that the cosmic beat in his being is ever decreasing, while the tensions of his waking-consciousness become more and more dangerous. It must be remembered that in a microcosm the animal, waking side supervenes upon the vegetable side, that of being, and not vice versa. Beat and tension, blood and intellect, Destiny and Causality are to one another as the country-side in bloom is to the city of stone, as something existing _per se_ to something existing dependently. Tension without cosmic pulsation to animate it is the transition to nothingness. But Civilization is nothing but tension. The head, in all the outstanding men of the Civilizations, is dominated exclusively by an expression of extreme tension. Intelligence is only the capacity for understanding at high tension, and in every Culture these heads are the types of its final men--one has only to compare them with the peasant heads, when such happen to emerge in the swirl of the great city’s street-life. The advance, too, from peasant wisdom--“slimness,” mother wit, instinct, based as in other animals upon the sensed beat of life--through the city-spirit to the cosmopolitan intelligence--the very word with its sharp ring betraying the disappearance of the old cosmic foundation--can be described as a steady diminution of the Destiny-feeling and an unrestrained augmentation of needs according to the operation of a Causality. Intelligence is the replacement of unconscious living by exercise in thought, masterly, but bloodless and jejune. The intelligent visage is similar in all races--what is recessive in them is, precisely, race. The weaker the feeling for the necessity and self-evidence of Being, the more the habit of “elucidation” grows, the more the fear in the waking-consciousness comes to be stilled by causal methods. Hence the assimilation of knowledge with demonstrability, and the substitution of scientific theory, the causal myth, for the religious. Hence, too, money-in-the-abstract as the pure causality of economic life, in contrast to rustic barter, which is pulsation and not a system of tensions.
