Dialectic and Dialogic

As has been previously discussed, Plato and Marx share Political Materialism and property Communalism. But, a primary difference between them is not as absolute as it might seem.  What Marx rejects about Plato's Classism is the thesis that variations in ability are immutable, not that given the predominant Means of Production in a period, Economic hierarchy is unavoidable.  Likewise not absolutely opposed is Dialectical Materialism and Plato's Dialogic.  For, what the former is antithetical to is the Dialectical Idealism of Hegel and Kant, whereas, as the aporetic dialogues indicate, the pattern of that Dialogic is not as contrived and schematic as it is sometimes taken to be.  Accordingly, as an alternative to both Dialectical Materialism and Dialectical Idealism, attributable to Plato might be the thesis that it is concrete Language that is inherently Dialectical.  For, in his system, Dialectics is a property of neither Matter nor Ideas, the former being inert, the latter being changeless.
