Discussion of the supervenience relation in the philosophical literature of recent years has become Byzantine in its intricacy and diversity. Subtle modulations of the basic concept have been tooled and retooled with increasing frequency, until supervenience has lost nearly all its original lustre as a simple and powerful tool for cracking open refractory philosophical problems. I present a conceptual model of the supervenience relation that captures all the important extant concepts (and suggests a few new ones) without ignoring the complexities uncovered during work over the past two decades. I test my analysis by applying it to the problem of defining physicalism, concluding that the thesis of physicalism is best captured by the conjunction of two supervenience relations.

The physicalist thesis that all entities are nothing over and above physical entities is often interpreted as appealing to a supervenience-based account of "nothing over and aboveness”, where, schematically, the A-entities are nothing over and above the B-entities if the A-entities supervene on the B-entities. The main approaches to filling in this schema correspond to different ways of characterizing the modal strength, the supervenience base, or the supervenience connection at issue. I consider each approach in turn, and argue that the resulting formulation of physicalism is compatible with physicalism’s best traditional rival: a naturalist emergentism. Others have argued that supervenience-based formulations of physicalism fail. My aim here, besides addressing the full spectrum of supervenience-based approaches, is to show how certain philosophical and scientific theses concerning naturalism, properties, and laws give us new reasons to think that supervenience-based formulations of physicalism are untenable.

Abstract Non-reductive physicalism is currently the most widely held metaphysic of mind. My aim in this essay is to show that supervenience physicalism?perhaps the most common form of non-reductive physicalism?is not a defensible position. I argue that, in order for any supervenience thesis to ground a legitimate form of physicalism, it must yield the right sort of determination relation between physical and non-physical properties. Then I argue that non-reductionism leaves one without any explanation for the laws that are implied by supervenience theses that deliver this determination relation.

Many authors have taken up the challenge of formulating physicalism as a supervenience thesis. These endeavors have met with varying response, but it seems that the general consensus still remains that a supervenience thesis that is both sufficient and necessary for physicalism has yet to be developed. Terence Horgan1 and Jaegwon Kim2 have most famously argued that supervenience theses are not sufficiently strong for physicalism. Nonetheless, several recent articles suggest that there are philosophers who still hold out hope for some type of supervenience of the mental upon the physical being, if not both sufficient and necessary, at least necessary for physicalism.3 In this paper, I will 1) investigate some of the motivation for finding a supervenience thesis that characterizes physicalism, 2) briefly review the types of supervenience theses that have been proposed as necessary (or necessary and sufficient) for physicalism, and 3) investigate in some detail the recent supervenience thesis proposed by Frank Jackson and expounded upon by Gene Witmer. Jackson, in his recent book, claims to have a supervenience thesis that is both necessary and sufficient for physicalism.
