paragraph_text: Pierre-Joseph Proudhon: property is theft
  
  In his 1840 treatise What is Property?, Pierre Proudhon answers with " Property is theft! ". In natural resources, he sees two types of property, de jure property (legal title) and de facto property (physical possession), and argues that the former is illegitimate. Proudhon's conclusion is that "property, to be just and possible, must necessarily have equality for its condition."
  
  His analysis of the product of labor upon natural resources as property (usufruct) is more nuanced. He asserts that land itself cannot be property, yet it should be held by individual possessors as stewards of humanity, with the product of labor being the producer's property. Proudhon reasoned that any wealth gained without labor was stolen from those who labored to create that wealth. Even a voluntary contract to surrender the product of work to an employer was theft, according to Proudhon, since the controller of natural resources had no moral right to charge others for the use of that which he did not labor to create did not own.
  
  Proudhon's theory of property greatly influenced the budding socialist movement, inspiring anarchist theorists such as Mikhail Bakunin who modified Proudhon's ideas, as well as antagonizing theorists like Karl Marx.
