It is the city that is wrong, and its creations can never be right; they may be improved; they can never be what they should.... Until the whole atrocious system of herding working people in close-built cities, by way of making them serviceable cogwheels in the capitalistic machine for grinding out rent and profit, comes to an end, the physical education of children will remain at best a pathetic compromise.

~ Voltairine De Cleyre

I think the difficulty lies in the immeasurable vanity of the human adult, particularly the pedagogical adult,… which does not permit him to recognize as good any tendency in children to fly in the face of his conceptions of a correct human being; to recognize that may be here is something highly desirable, to be encourage, rather than destroyed as pernicious…. [Y]our teacher has usually well-defined conceptions of what men and women have to be. And if a boy is too lively, too noisy, too restless, too curious, to suit the concept, he must be trimmed and subdued.

If this is the price to be paid for an idea, then let us pay. There is no need of being troubled about it, afraid, or ashamed. This is the time to boldly say, “Yes, I believe in the displacement of this system of injustice by a just one; I believe in the end of starvation, exposure, and the crimes caused by them; I believe in the human soul regnant over all laws which man has made or will make; I believe there is no peace now, and there will never be peace, so long as one rules over another; I believe in the total disintegration and dissolution of the principle and practice of authority; I am an Anarchist, and if for this you condemn me, I stand ready to receive your condemnation.

Says the Cardinal: Freethought leads to Atheism, to the destruction of social and civil order, and to the overthrow of government. I accept the gentleman's statement; I credit him with much intellectual acumen for perceiving that which many freethinkers have failed to perceive: accepting it, I shall do my best to prove it, and then endeavor to show that this very iconoclastic principle is the salvation of the economic slave and the destruction of the economic tyrant....Hence the freethinker who recognizes the science of astronomy, the science of mathematics, and the equally positive and exact science of justice, is logically forced to the denial of supreme authority. For no human being who observes and reflects can admit a supreme tyrant and preserve his self-respect. No human mind can accept the dogma of divine despotism and the doctrine of eternal justice at the same time; they contradict each other, and it takes two brains to hold them. The cardinal is right: freethought does logically lead to atheism, if by atheism he means the denial of supreme authority.
