"it is easy to centralize power but impossible to centralize all knowledge which is distributed over many individual minds... Unable to ascertain what is in the minds of many individuals,( the state ) just try to control and stereotype interests and beliefs by education and propaganda. But this attempt ( by the state) to exercise power over minds must destroy the last possibility of finding out what people really think, for it is clearly incompatible with the free expression of thought, especially of critical thought. Ultimately it must destroy knowledge; and the greater the gain in power, the greater will be the loss of knowledge." - Karl Popper.
