On Genius:

>'An ordinary genius is a fellow that you and I would be just as good as, if we were only many times better. There is no mystery as to how his mind works. Once we understand what he has done, we feel certain that we, too, could have done it. It is different with the magicians. They are, to use mathematical jargon, in the orthogonal complement of where we are and the working of their minds is for all intents and purposes incomprehensible. Even after we understand what they have done, the process by which they have done it is completely dark.'

This is another way to characterize the intuitive ('magician') as opposed to the analytical ('ordinary genius') scientists or mathematician (and probably, ceteris paribus, artist as well); we see the intuitive worker as intrinsically more 'creative' just because the origins of his creativity are hidden in the unfamiliar cliffs and caves of the unconscious.<
