A book is the work of a mind, doing its work in the way that a mind deems
best. That's dangerous. Is the work of some mere individual mind likely to
serve the aims of collectively accepted compromises, which are known in the
schools as 'standards'? Any mind that would audaciously put itself forth to
work all alone is surely a bad example for the students, and probably, if
not downright antisocial, at least a little off-center, self-indulgent,
elitist. ... It's just good pedagogy, therefore, to stay away from such
stuff, and use instead, if film-strips and rap-sessions must be
supplemented, 'texts,' selected, or prepared, or adapted, by real
professionals. Those texts are called 'reading material.' They are the
academic equivalent of the 'listening material' that fills waiting-rooms,
and the 'eating material' that you can buy in thousands of convenient eating
resource centers along the roads.
