→ WHAT IT COVERS Graham Harman joins the Partially Examined Life hosts for part two of a discussion on his book *Waves and Stones*, covering object-oriented ontology's core tension between discrete objects and continua, the limits of skepticism, how undermining and overmining fail to exhaust objects, and whether any direct access to reality is philosophically defensible. → KEY INSIGHTS - **Skepticism's self-defeating structure:** Any theory claiming mediated access to reality must already assume some direct access to motivate that claim. Hegel's move to "doubt the doubt" captures this: without assuming bodies, eyes, light, and causality as real, there is no basis for arguing that perception mediates reality. Skeptical frameworks undermine themselves by relying on the very phenomena they claim are unreliable. - **Undermining vs. overmining as a diagnostic tool:** Harman's framework identifies two default explanatory moves — reducing a thing to its components (undermining) or exhausting it through its effects and uses (overmining). Neither captures the object itself. Gatorade's chemical composition misses emergent properties; its functional uses are inexhaustible. Objects occupy a mezzanine level between these two forms of literal explanation, making complete knowledge structurally impossible. - **Dual mining as scientific materialism's blind spot:** Scientific materialism typically combines both failures simultaneously — positing fundamental particles (undermining) while claiming mathematical exhaustion of those particles (overmining). Harman calls this dual mining. Recognizing this pattern reveals why even the most rigorous scientific frameworks cannot fully capture the objects they describe, a structural limitation rather than a temporary gap in knowledge. - **Continua vs. discrete objects in causation:** Two discrete objects — Harman uses billiard balls — cannot make direct contact. They interact only through a continuous medium such as space. This means causal interaction requires both discrete objects and a continuum, neither alone is sufficient. The collision cannot be described without reference to a larger system, but that system need not extend to the entire universe. - **Fictional and sensual objects are categorically distinct from real ones:** All sensual objects, including perceptions that correspond to real things, are different objects from the real things they represent. Harman clarifies that object-oriented ontology is not a sorting exercise separating real perceptions from unreal ones. Rather, it establishes a structural rift between two object types. Fictional objects like Sherlock Holmes can become real in a limited sense when they develop objective, contestable properties exceeding any single interpretation. - **Aristotle's physics-metaphysics split as a key interpretive move:** Harman argues, against standard Aristotle commentary, that the *Physics* addresses the continuous while the *Metaphysics* addresses the discrete. This reframing places the continuous-discrete opposition at the center of Aristotle's philosophy. It also clarifies why Aristotle rejects pure flux: change requires persistent unities to change, making process-only ontologies incoherent without discrete substances as their substrate. → NOTABLE MOMENT Harman pushes back on the idea that mathematical objects can be fully known, citing Lakatos's *Proofs and Refutations* to argue that mathematical truth undergoes theory-change resembling scientific paradigm shifts. This challenges the common assumption that a simple geometric object like a three-inch square could ever be completely and permanently exhausted by description. 💼 SPONSORS [{"name": "Shopify", "url": "https://shopify.com/pel"}, {"name": "Fundera by NerdWallet", "url": "https://nerdwallet.com/pel"}, {"name": "HelloFresh", "url": "https://hellofresh.com/pel10fm"}] 🏷️ Object-Oriented Ontology, Metaphysics, Epistemology, Philosophy of Science, Graham Harman, Aristotle
