Why nonliterate societies cannot see films or photos without 
much training.

*     Since the present object is to elucidate the effective 
causality of phonetic writing in setting up new kinds of 
perception, let us turn to a paper (7) by Professor John Wilson 
of the African Institute of London University. For literate

three dimensions or perspective. We assume that this is normal 
vision and that no training is needed to view photos or films.
