Abstract

This chapter has two main complementary goals. First, it analyzes the main ontological ideas of Gustavo Bueno’s discontinuous materialism in contrast with other philosophical systems. Second, it explores some of the main ontological questions and issues still open in this system of thought, while advancing some possible paths of resolution. In order to do this, I follow a double general definition of philosophical materialism. Positively, materialism, in general, names the branch of philosophical worldviews that identify being (i.e. the “ὅντος” of ontology) with matter, understood in its broadest sense as changeability and plurality (partes extra partes). Negatively, materialism denies the existence of disembodied living beings and hypostatized ideas. Within this general framework, I then locate the specific ontological characteristic of discontinuous materialism in the rejection of any attempt to hypostatize any element, property, state or relation of reality. Like the Medusa’s gaze, hypostasizing metaphysics turns parts of the complex interplay of continuities and discontinuities that constitutes reality into stone. I then conduct a comparison between discontinuous materialism and other philosophies, in particular Mario Bunge’s systemic materialism, physicalism, ontotheology, and speculative realism(s). This approach aims at opening new avenues for philosophical research for both metaphysics in general and materialist philosophy in particular.
