 Marx, Karl, The German Ideology Prometheus Books, (1998), Theses on Feuerbach No. III, Pages 569-574 – ‘The materialist doctrine concerning the changing of circumstances and upbringing forgets that circumstances are changed by men and that it is essential to educate the educator himself. This doctrine must, therefore, divide society into two parts, one of which is superior to society. The coincidence of the changing of circumstances and of human activity or self-changing can be conceived and rationally understood only as revolutionary practice.’
