"The Man of Genius may at the same time be, indeed is commonly, an Artist, but the two are not to be confounded. The Man of Genius,referred to mankind, is an originator, an inspired or demonic man, who produces a perfect work in obedience to laws yet unexplored. The artist is he who detects and applies the law from observation of the works of Genius, whether of man or nature. The Artisan is he who merely applies the rules which others have detected. There has been no man of pure Genius, as there has been none wholly destitute of Genius."
