Famous quotes containing the words system and/or theory:
“The human body is not a thing or substance, given, but a continuous creation. The human body is an energy system ... which is never a complete structure; never static; is in perpetual inner self-construction and self-destruction; we destroy in order to make it new.”
—Norman O. Brown (b. 1913)
“Every theory is a self-fulfilling prophecy that orders experience into the framework it provides.”
