Pierre-Joseph Proudhon

He is the first famous person in history to call himself an anarchist.

He is famous for the quotes "Anarchy is Order" and "Property is Theft."

"Property is Theft"
He first wrote this in 1840, in his book ''What is Property? Or, an Inquiry into the Principle of Right and of Government.''

Here is the quote:"If I were asked to answer the following question: What is slavery? and I should answer in one word, It is murder!, my meaning would be understood at once. No extended argument would be required to show that the power to remove a man's mind, will, and personality, is the power of life and death, and that it makes a man a slave. It is murder. Why, then, to this other question: What is property? may I not likewise answer, It is robbery!, without the certainty of being misunderstood; the second proposition being no other than a transformation of the first?"
