Marx’s early theory of labour and alienation originates from idealist concepts of spontaneity and formativity. His ideas of socialism and emancipation in the 1840s reprise aspects of Kantian autonomy and heteronomy and follow Fichte in linking labour with spontaneity. Marx formulates the dialectic of the will in a way favourable to the moment of particularity as membership in a social class, and sees one particular class as simultaneously a vehicle of universal interest and revolutionary transformation. Quantitative change is insufficient though necessary: a merely distributive socialism might enhance the living conditions of the workers, but would leave intact structures of exploitation which deprive workers of their agency as well as their happiness. His theory of history and emancipation, recently described as a self-actualisation account, can be more precisely identified as a variant of post-Kantian perfectionism, which, like Feuerbach’s, contains a strong admixture of pre-Kantian elements. This blending of heterogeneous elements has profound theoretical and practical consequences, notably in the absence of a developed concept of right.
