Materialism, Inversion, Eversion

Marx's previously discussed conflation of Metaphysical Materialism and Epistemological Materialism reflects the duality of what he is responding to--Hegel's concept of Mind, which is both Metaphysical Substance and Epistemological Subject. Now, the image of an 'inversion' of Hegelianism, i. e. "turning it on its head", implies a hierarchical relation, specifically one found in the Metaphysical dimension of Hegelianism--Heaven and Earth. However, no corresponding hierarchy obtains in its Epistemological dimension. Instead, a different structure there suggests an alternative reversal of Hegelianism. For, a notable feature of Hegelian Phenomenology, and of many other post-Cartesian theories, is the internalization of 'the world'. Accordingly, one reversal of that concept is its eversion, i. e. from the 'world inside one' to 'one in the world'. Now, in Marxism, what effects that eversion is the emergence of Collective-Consciousness, which is not necessarily a Materialist concept.
