Mutualism and Property

Proudhon's Mutualist theory of Property has two main principles: 1. The product of one's own labor is inalienably one's own, and 2. The means of production is collectively owned.  Now, while such an arrangement eliminates much exploitation, it is not completely coherent.  For, it leaves undeterminable the status both of the production of means of production, such as tools, and of the collective production of goods.  Common to the two problems is the absence of a formulation of the relation between My and Our, an absence that originates in that between I and We.
