Herman Bernstein, “Auguste Rodin,“ With Master Minds, (New York: Universal Series Publishing Co., 1913), p.128:
Artist do not love their work if they do not understand it. All that is done in haste and in a state of excessive exaltation should be destroyed. Lombroso and others who imagine that genius borders on insanity are absolutely wrong. Genius is order personified, the concentration of abilities and level-mindedness of the masses. My work has often been styled the product of inspiration and exalted enthusiasm. I am just the opposite of an enthusiast. My temperament is even. I am not a dreamer. I am rather a mathematician.
