Abstract
Drawing on resources from debates concerning the metaphysics of powers, this essay introduces a novel approach to the relationship between the more- and less-complex. Flat Holism preserves some key reductionist commitments, as it involves no radical ontological novelty, for instance, and is consistent with a one- or no-level ontology. It also, however, adopts the emergentist idea that the whole or context plays a crucial, metaphysically determinative role. The commitments of Flat Holism are explored and delimited through comparison with two ‘nearby neighbour’ accounts: Sydney Shoemaker’s Micro-latency account and Carl Gillett’s Mutualism. Some potential advantages of Flat Holism are discussed in the final section of the essay.
