As told by Aldus Huxley in “Doors of Perception”
One day, towards the end of his life, Blake met Constable at Hampstead adn was shown one o fthe younger artist’s sketches. In spite of his contempt for naturalistic art. the old visionary knew a good thing when he saw it — except of course, when it was by Rubens. “This is not drawing,” he cried. “This is inspiration!” “I had meant it to be drawing” was Constable’s characteristic answer. Both men were right.
