Kandinsky was an optimist; he had been interested, at first, in fairy tales and legends and chivalrous themes of the past, but he then became increasingly interested, after 1908, in formulating what he called the art of the future rather than indulging in romantic visions of the past. Kubin, on the other hand was a pessimist, always haunted by the past and suspicious of the future. This basic difference in their temperaments made their discussions all the more fruitful, and their friendship was the more intense.
