Summary |
Inter-level metaphysics pertains to the question of whether reality has a leveled structure, and if so, what relations underpin this structure. That reality has a leveled structure is often motivated by attention to special scientific entities, features, and laws, which appear to cotemporally depend on lower-level, ultimately physical entities and features, but also to be ontologically and perhaps also causally distinctive as compared to lower-level entities, features, and laws; ordinary experience of dependent macro-entities and features is also seen as motivating leveled structure. Candidate relations offered as connecting goings-on at different levels include supervenience, mereological composition, functional or subset-of-powers-based realization, the determinable-determinate relation, causal mechanism, and primitive Grounding, among others. Deflationary accounts of leveled structure include reductionist approaches, according to which seemingly higher-level goings-on are in fact type or token identical to (typically massively complex) lower-level goings-on, and eliminativist approaches, according to which higher-level goings-on do not exist, even as reducible to lower-level goings-on. |
