Theories

"Without theory, experience has no meaning. Without
theory, one has no questions to ask. Hence without theory,
there is no learning. Theory is a window into the world.
Theory leads to prediction. Without prediction, experience
and examples teach nothing. To copy an example of
success, without understanding it with the aid of theory,
may lead to disaster." Deming, W. E. 1993. The New
Economics For Industry, Government, Education, p. 106.
