Cultural homogenization and social regimentation
resulting from the creeping monotony of overorganized
and overtechnicized life, of standardized patterns of
education, mass communication, and entertainment, will
make it progressively more difficult to exploit fully the the
biological richness of our species and may handicap the
further development of civilization. We must shun uniformity
of surroundings as much as absolute conformity in behavior
and tastes. We must strive instead to create as many
diversified environments as possible. Richness and diversity
of physical and social environments constitute an essential
criteria of functionalism, whether in the planning of cities,
the design of dwellings, or the management of individual life.
