Professionalism merges the individual into patterns of total environment. Amateurism seeks the development of the total awareness of the individual and the critical awareness of the groundrules of society. The amateur can afford to lose.

The groundrules provided by the mass response of his colleagues serve as a pervasive environment of which he is contentedly unaware. The 'expert' is the man who stays put.
