"If you work by reason, you grow rough-edged; if you choose to dip your oar in sentiment's stream, it will sweep you away. Demanding your own way only serves to constrain you. However you look at it, the human world is not an easy place to live . . . I suppose you could say that the artist is one who lives in a three-cornered world, in which the corner that the average person would call 'common sense' has been sheared off from the ordinary four-square world that the normal inhabit."
