Anarchy is rarely or never upheld with consistency. In the pedagogy of Rousseau, there is a set purpose to let the child be guided by natural necessity rather than by human command, and to let him learn from the experience of physical facts rather than by obedience. “Keep the child solely dependent on things; you will have followed the order of Nature in the process of his upbringing. Never oppose to his unreasonable wishes any but physical obstacles or punishments resulting from the actions themselves — he will remember these punishments in similar situations. It is enough to prevent him from doing evil without forbidding him to do it …” (Emile, II). Remarkably, the theory that the method of authority is a poor substitute for the pedagogical power of nature has been accepted, in varying degree of enthusiasm or reluctance, by most schools of pedagogy and has demonstrated lasting power. Yet the authority of parents and tutors is present throughout pedagogical theories, even when it is passed over in silence. Childhood is the domain where the suppression of all authority is obviously impossible. The most radical constructs of anarchy, as soon as they rise above the level of idle rhetoric, admit of qualifications so far at least as the immature part of mankind is concerned. Anti-authoritarian theorists, with few exceptions if any, do not mean that authority should disappear or that it can ever cease to be a factor of major importance in human affairs. What thinkers opposed to authority generally mean is that authority can never be vindicated except by such deficiencies as are found in children, in the feeble-minded, the emotionally unstable, the criminally inclined, the illiterate, and the historically primitive.
