" The everlasting and exclusive coming-to-be, the impermanence of everything actual, which constantly acts and comes-to-be but never is, as Heraclitus teaches it, is a terrible, paralyzing thought. Its impact on men can most nearly be likened to the sensation during an earthquake when one loses one's familiar confidence in a firmly grounded earth. It takes astonishing strength to transform this reaction into its opposite, into sublimity and the feeling of blessed astonishment.
