Scientific Socialism and Practical Materialism.

Marx and Engels classify their program as 'Scientific Socialism', which they distinguish from 'Utopian Socialism'. By 'Science', they mean 'Dialectical Materialism'. Now, as articulated in the Theses on Feuerbach, the system is also 'Practical Materialism'. Thus required is how a Dialectical pattern governed by Necessity can also entail a voluntary phase. In particular, what is required is an explanation of how the transition from the consciousness of a Contradiction, i. e. of Class-Conflict, is followed by its resolution both necessarily and voluntarily. However, they offer no such account, in the absence of which Scientific Socialism and Practical Materialism remain apparently irreconcilable.
