Anarchism, Mutualism, Kantianism

Mutualism can be conceived as an instance of Kantian Morality--of the feature characterized as the End-in-Itself Duty.  For, treating another as an End in that system entails both elements of a Mutualist exchange--voluntary participation, i. e. Autonomy, and fairness, i. e. respect for the interest of another.  Now, one of the looser transitions in Kant's system is that from the Fundamental Principle of Pure Practical Reason to this Duty, i. e. the latter admirably enriches the former, but is not rigorously derived from it.  Similarly, Mutualism enhances Proudhon's Anarchism, but it is not logically entailed by it.  That looseness can explain why Wolff's Kantian defense of Anarchism, based on the concept of Autonomy, bypasses the parallel Kantianism of Proudhon's Mutualism.
