A man is lying under machine-gun fire on a street in an embattled city. He looks at the pavement and sees a very amusing sight: the cobblestones are standing upright like the quills of a porcupine. The bullets hitting against their edges displace and tilt them. Such moments in the consciousness of a man judge all poets and philosophers. Let us suppose, too, that a certain poet was the hero of the literary cafes, and wherever he went was regarded with curiosity and awe. Yet his poems, recalled in such a moment, suddenly seem diseased and highbrow. The vision of the cobblestones is unquestionably real, and poetry based on an equally naked experience could survive triumphantly that judgment day of man’s illusions.
