To evoke the emotions of life he must use representation. Thus a man will paint an execution, and, fearing to miss with his first barrel of significant form, will try to hit with his second by raising an emotion of fear or pity. But if in the artist an inclination to play upon the emotions of life is often the sign of a flickering inspiration, in the spectator a tendency to seek, behind form, the emotions of life is a sign of defective sensibility always. It means that his aesthetic emotions are weak or, at any rate, imperfect. Before a work of art people who feel little or no emotion for pure form find themselves at a loss.
