My hatred of privilege and human authority was unbounded; perhaps at times I have been guilty, in my indignation, of confounding persons and things; … - Pierre-Joseph Proudhon

It is better to enlighten men’s minds than to teach them to be obstinate in their prejudices.

Habit, like a second nature, has the power of fixing in the mind new categorical forms derived from the appearances which impress us, and by them usually stripped of objective reality, but whose influence over our judgments is no less predetermining than that of the original categories. Hence we reason by the eternal and absolute laws of our mind, and at the same time by the secondary rules, ordinarily faulty, which are suggested to us by imperfect observation. This is the most fecund source of false prejudices, and the permanent and often invincible cause of a multitude of errors. The bias resulting from these prejudices is so strong that often, even when we are fighting against a principle which our mind thinks false, which is repugnant to our reason, and which our conscience disapproves, we defend it without knowing it, we reason in accordance with it, and we obey it while attacking it. Enclosed within a circle, our mind revolves about itself, until a new observation, creating within us new ideas, brings to view an external principle which delivers us from the phantom by which our imagination is possessed.

I have made every effort to obtain exact information, comparing doctrines, replying to objections, continually constructing equations and reductions from arguments, and weighing thousands of syllogisms in the scales of the most rigorous logic. In this laborious work, I have collected many interesting facts which I shall share with my friends and the public as soon as I have leisure. But I must say that I recognized at once that we had never understood the meaning of these words, so common and yet so sacred: Justice, equity, liberty; that concerning each of these principles our ideas have been utterly obscure; and, in fact, that this ignorance was the sole cause, both of the poverty that devours us, and of all the calamities that have ever afflicted the human race.
