It is widely thought that mind–body substance dualism is implausible at best, though mere “property” dualism is defensible and even flourishing. This paper argues that substance dualism is no less plausible than property dualism and even has two advantages over it.

Panpsychism may be roughly defined as a view that at least some of the properties constituting the fundamental level of reality are mental or proto-mental. Despite its long history, it has been revived in recent discussions as a solution to the problems raised by the mind, especially to the so-called hard problem of consciousness. Contemporary panpsychism differs significantly from incarnations known from the history of philosophy mainly due to the fact that the former is often combined with so-called Russellian monism. (...) According to Russellian monism, the intrinsic properties of physical things remain unknown. This encourages panpsychists to argue that those properties are in fact mental. In my paper, I examine the three most common arguments for panpsychism: the Continuity Argument, the Hegelian Argument, and the Agnostic Argument. I take a closer look at each of them to assess their advantages and weaknesses. As I point out, the way in which one argues implies the version of panpsychism one adopts. This turns out to be especially important with regard to the Hegelian Argument and the Agnostic Argument. Both can be combined with Russellian monism, resulting in Russellian panpsychism. However, I claim that the philosophical consequences of these arguments are different, so it is legitimate to distinguish two kinds of Russellian panpsychism. In conclusion, I hold that there are reasons to prefer panpsychism based on the Agnostic Argument, which is more promising, as it responds to some general problems of panpsychism. (shrink)

The emergentist position that R. Keith Sawyer has formulated, nonreductive individualism, contains three propositions. First, that social characteristics must always be realized in individuals; second, that it is nevertheless possible to understand social properties as irreducible; and third, that therefore it is possible to demonstrate how social properties are able to exercise independent causal influences on individuals and their properties. It is demonstrated that Sawyer is not able to meet an objection that Kim has formulated against the analogous position in (...) the philosophy of mind. In his defense of the claim of irreducibility Sawyer refers to Fodor’s argument about multiple realizability, but this line of argument cannot preserve the claim for downward causation because Fodor’s claim for irreducibility rests on assumptions that are not compatible with a systematic formulation of downward causation. The article proposes a reading of Fodor’s argument that is consistent with individualism but not with nonreductive individualism. (shrink)

Substance dualism is the view that there are two fundamentally different kinds of substances: physical and mental. By contrast, according to property dualism there is only one kind of substance (physical) but two fundamentally different kinds of properties: physical and mental. Property nominalism is the view that there are neither repeatable nor non-repeatable fundamentally predicable entities (i.e. neither universals nor tropes) and that things being a certain way or being related in a certain way must ultimately be accounted for in (...) terms of concrete particulars. In this paper, we consider a number of different kinds of property nominalism and argue that none of them sits well with property dualism. We pay special attention to the question of what it could mean for a property to count as mental given different nominalistic accounts of properties. Our conclusion is that property nominalism and property dualism are not a stable match. This is surprising, since property dualism has usually been understood as a thesis that is neutral about the nature of fundamental ontological categories and the relation between them. (shrink)

Emergence is a notorious philosophical term of art. A variety of theorists have appropriated it for their purposes ever since George Henry Lewes gave it a philosophical sense in his 1875 Problems of Life and Mind. We might roughly characterize the shared meaning thus: emergent entities (properties or substances) ‘arise’ out of more fundamental entities and yet are ‘novel’ or ‘irreducible’ with respect to them. (For example, it is sometimes said that consciousness is an emergent property of the brain.) Each (...) of the quoted terms is slippery in its own right, and their specifications yield the varied notions of emergence that we discuss below. There has been renewed interest in emergence within discussions of the behavior of complex systems and debates over the reconcilability of mental causation, intentionality, or consciousness with physicalism.
