runs an engine and learns to know and love his machine almost as though

of meaning which may be expressed by the use of words. In just the same

which we, who possess an uneducated ear, cannot know; and the artist
also has a wondrous range of color, while we, who are not sensitive to
color, know only a few of the primal colors.
