“ Swedenborgianism, symbolism, socialism, appealed to him as they might to a mystic or an idealist. He aspired to the perfect unities, and was impatient of structural foundations. This was his attitude towards painting. He sought the sentiment, the light, air, and colour of nature, but was put out by nature’s forms. ”
