Dialectical Materialism is a science and framework which applies Dialectics to the content of reality. It's about a revolt against Modern Consciousness. It's about a recognition of the limits in the Inner-Subjectivity of Modernity, how we interrelate to one-another (Intersubjectivity), and how this subjectivity is mitigated, as well as the realm of Objectivity - how we reconnect our minds and create an alternative to Modernity.
"(Dialectical) Materialism does not focus on supreme substance (atoms/particles), it focuses on the materiality of differences and contradictions ... What gives it it's difference? The difference is the Real" - Haz Al-Din
