ABSTRACT
In this chapter I want to show that in the writing of Karl Marx we can identify a philosophical materialism within which the grounds for what I want to refer to as genuinely objective theories of ontology and epistemology can be located. But I want also to show that this achievement owes a considerable amount to principles in the philosophy of the sciences that have striking similarities to two of his predecessors in the German intellectual tradition of critique, namely Kant and Hegel. In short, I wish to demonstrate that Marxian materialist objectivism represents a materialist inversion of Hegelian and Kantian notions of objectivity in the natural and social sciences.
