Warren, Art critic on the "Sun News Pictorial" newspaper from 1951 to 1971 and member of modernist Contemporary Art Society, proved himself a vocationalist in contrast to Duncan, committed to running a ‘college’, rather than a ‘technical school’, which trained “creative designers, craftsmen and draughtsmen” but not “artists in a vacuum” and least of all, “oil painters.” In teaching theory, knowledge of art forms, encapsulated by Roger Fry in "Vision and Design "(1926), was to be imparted but not “simply a History of Art”.
