Dialectical Materialism and Revolution

In formal Dialectics. a Contradiction is resolved as a Synthesis in which both terms are preserved, e. g. Being and Nothingness as Becoming. Correspondingly, in Dialectical Materialism, class-less Socialism resolves the conflict of Capitalist classes. Now, another Marxist concept of the transition from Capitalism to Socialism is Revolution, the significant characteristic of which in social contexts is Overturning. But, implicated, though not always rigorously addressed, in that imagery is the concomitant fate of the object of Overturning, i. e. of the antecedent upper class. Though, strictly speaking, the latter becomes the underclass as a result of a Revolution, as a matter of historical fact, its members have usually been eliminated, thereby yielding a 'class-less' society, not one that synthesizes the conflicting classes of Capitalism, but one constituted by a strata-less triumphant working class. So, perhaps the greatest challenge to Dialectical Materialism comes from within Marxism itself, i. e. from the concept of Revolution.
