“Functional communication is only the outer layer of the one- dimensional universe in which man is trained to target—to translate the negative into the positive so that he can continue to function, reduced but fit and reasonably well. The institutions of free speech and freedom of thought do not hamper the mental coordination with the established reality. What is taking place is a sweeping redefinition of thought itself, of its function and content. The coordination of the individual with his society reaches into those layers of the mind where the very concepts are elaborated which are designed to comprehend the established reality. These concepts are taken from the intellectual tradition and translated into operational terms—a translation which has the effect of reducing the tension between thought and reality by weakening the negative power of thought.”
