"What Plato lacks above all, perhaps, is the Heracleitean sense of flux and change; he is too anxious to have the moving picture of this world become a fixed and still tableau. He loves order exclusively, like any timid philosopher; he has been frightened by the democratic turbulence of Athens into an extreme neglect of individual values; he arranges men in classes like an entomologist classifying flies; and he is not averse to using priestly humbug to secure his ends. His state is static; it might easily become an old-fogey society, ruled by inflexible octogenarians hostile to invention and jealous of change. It is mere science without art; it exalts order, so dear to the scientific mind, and quite neglects that liberty which is the soul of art; it worships the name of beauty, but exiles the artists who alone can make beauty or point it out. It is a Sparta or a Prussia, not an ideal state."
