Mutualism and Solidarity

Proudhon conceives his Mutalist Anarchism to be Socialist, i. e. an associative solidarity.  However, one problem with his concept is that there is no systematic relation between Mutuality and Solidarity.  For, the former is constituted by a multiplicity of Is, while the latter consists in a We.  Similarly, Kant's Kingdom of Ends is an aggregate of Rational agents that is outside the scope of Synthesis--Quantity in his system is applicable to only Phenomenal entities, not to Noumenal ones like Rational agents, and, hence the aggregate cannot be unified while retaining internal distinctions.  In other words, a Mutualist collective can never be more than a concatenation of Individuals, i. e. can never solidify as a We.
