Is It Practical Ontology or Is It the Dialectical Materialist Theory of Material Monism

In the discussions regarding the philosophical system and the essence of Marxism, ontological theory is a very important issue. At the moment, there are three basic sets of opinions on this problem, namely, the opinion that Marxism, in fact, does not consist of any ontological theory (or, if you will, the antiontological theory), the opinion that Marxist ontology is a theory of practical ontology, and the opinion that it is a dialectical materialist theory of material monism. The latter two acknowledge that Marxist philosophy does involve an ontological theory. The following article, proceeding on this premise, will focus on whether the ontological theory in Marxist philosophy is a theory of practical ontology or a dialectical materialist theory of material monism. I would like to propose a number of topics for concrete discussion surrounding this general issue.
