Dans son article From Nihilism to Monism, Jonathan Schaffer montre que les partisans du Nihilisme de la Composition ont de bonnes raisons d’accepter le Monisme d’Existence plutôt que le Nihilisme. De manière analogue, nous souhaitons montrer ici que les partisans de l’Universalisme de la Composition ont de bonnes raisons d’accepter le Monisme de Priorité. Pour montrer cela, nous allons proposer et défendre l’argument suivant : Prémisse 1. Si l’Universalisme de la Composition est vrai alors le Cosmos existe. Prémisse 2. Si (...) le Cosmos existe alors le Cosmos est la seule entité concrète basique. Conclusion. Si l’Universalisme de la Composition est vrai alors le Cosmos est la seule entité concrète basique.

Contrary to widely shared opinion in analytic metaphysics, E.J. Lowe argues against the existence of relations in his posthumously published paper There are probably no relations (2016). In this article, I assess Lowe’s eliminativist strategy, which aims to show that all contingent “relational facts” have a monadic foundation in modes characterizing objects. Second, I present two difficult ontological problems supporting eliminativism about relations. Against eliminativism, metaphysicians of science have argued that relations might well be needed in the best a posteriori (...) motivated account of the structure of reality. Finally, I argue that, by analyzing relational inherence, trope theory offers us a completely new approach to relational entities and avoids the hard problems motivating eliminativism. (shrink)

Physicist Max Tegmark argues that if there are infinite universes or sub-universes, we will encounter our exact duplicates infinite times, the nearest within 10^10^115 m. Tegmark assumes Humean supervenience and a finite number of possible combinations of elementary quantum states. This paper argues on the contrary that Tegmark’s argument fails to hold if possible thoughts, persons, and life histories are all infinite in number. Are there infinite thoughts we could possibly think? This paper will show that there are. If so, (...) then it is not only Tegmark’s specific claim about our duplication that is called into question. We additionally acquire another strong argument against Humean supervenience. (shrink)

It has been argued that Humean Supervenience is threatened by the existence of quantum entanglement relations. The most conservative strategy for defending HS is to add the problematic entanglement relations to the supervenience basis, alongside spatiotemporal relations. In this paper, I’m going to argue against this strategy by showing how certain particular cases of tripartite entanglement states – i.e. GHZ states – posit some crucial problems for this amended version of HS. Moreover, I will show that the principle of free (...) recombination – which is strictly linked to HS – is severely undermined if we add entanglement relations to the supervenience basis. I conclude that the conservative move is very unappealing, and therefore the defender of HS should pursue other, more controversial, strategies. (shrink)

The trope bundle theories of objects are capable of analyzing monadic inherence (objects having tropes), which is one of their main advantage. However, the best current trope theoretical account of relational tropes, namely, the relata specific view leaves relational inherence (a relational trope relating two or more entities) primitive. This article presents the first trope theoretical analysis of relational inherence by generalizing the trope theoretical analysis of inherence to relational tropes. The analysis reduces the holding of relational inherence to the (...) obtaining of certain other facts about entities of the trope theoretical category system. Moreover, I show that the analysis can deal with asymmetric and non-symmetric relations by assuming that all relation-like tropes are quantities. Finally, I provide an account of the spatial location of tropes in the difficult case in which tropes contribute to determining of the location of other entities. (shrink)

Tim Maudlin has influentially argued that Humeanism about laws of nature stands in conflict with quantum mechanics. Specifically Humeanism implies the principle Separability: the complete physical state of a world is determined by the intrinsic physical state of each space-time point. Maudlin argues Separability is violated by the entangled states posited by QM. We argue that Maudlin only establishes that a stronger principle, which we call Strong Separability, is in tension with QM. Separability is not in tension with QM. Moreover, (...) while the Humean requires Separability to capture the core tenets of her view, there's no Humean-specific motivation for accepting Strong Separability. We go on to give a Humean account of entangled states which satisfies Separability. The core idea is that certain quantum states depend upon the Humean mosaic in much the same way as the laws do. In fact, we offer a variant of the Best System account on which the systemization procedure that generates the laws also serves to ground these states. We show how this account works by applying it to the example of Bohmian Mechanics. The 3N-dimensional configuration space, the world particle in it and the wave function on it are part of the best system of the Humean mosaic, which consists of N particles moving in 3-dimensional space. We argue that this account is superior to the Humean account of Bohmian Mechanics defended by Loewer and Albert, which takes the 3N-dimensional space, and its inhabitants, as fundamental. (shrink)

This paper considers two aspects of Lewis 's metaphysics to which spatiotemporal relations appear central, with the aim of showing them to be less so. First, Lewis reluctantly characterises what it is for two things to be part of the same possible world in terms of an analogically spatiotemporal category of relations, rather than a wider natural external category. But Lewis 's reason for restricting himself to the narrower category is unpersuasive. Second, Humean supervenience is formulated with spatiotemporal relations at (...) its core. But that seems negotiable. A reason for caring about this is that quantum mechanics is supposed to threaten Lewis 's metaphysics by introducing natural external relations that are not spatiotemporal, hence the interest in how central spatiotemporal relations really are.

Trope theories aim to eschew the primitive dichotomy between characterising (properties, relations) and characterized entities (objects). This article (in Finnish) presents a new trope theoretical analysis of relational inherence as the best way out of the impasse created by the alleged necessity to choose between an eliminativist and a primitivist ("relata-specific") view about relations in trope theory.

The interactivist model has explored a number of consequences of process metaphysics. These include reversals of some fundamental metaphysical assumptions dominant since the ancient Greeks, and multiple further consequences throughout the metaphysics of the world, minds, and persons. This article surveys some of these consequences, ranging from issues regarding entities and supervenience to the emergence of normative phenomena such as representation, rationality, persons, and ethics.

The present study attempts to provide a consistent and coherent account of what the world could be like, given the conceptual framework and results of contemporary quantum theory. It is suggested that standard quantum mechanics can, and indeed should, be understood as a realist theory within its domain of application. It is pointed out, however, that a viable realist interpretation of quantum theory requires the abandonment or radical revision of the classical conception of physical reality and its traditional philosophical presuppositions. (...) It is argued, in this direction, that the conceptualization of the nature of reality, as arising out of our most basic physical theory, calls for a kind of contextual realism. Within the domain of quantum mechanics, knowledge of 'reality in itself', 'the real such as it truly is' independent of the way it is contextualized, is impossible in principle. In this connection, the meaning of objectivity in quantum mechanics is analyzed, whilst the important question concerning the nature of quantum objects is explored. (shrink)

Methods and goals in philosophy are discussed by first describing an ideal, and then looking at how the ideal might be approached. David Lewis’s work in metaphysics is critically examined and compared to analogous work by Mackie and Carnap. Some large-scale philosophical systematic work, especially in metaphysics, is best treated as model-building, in a sense of that term that draws on the philosophy of science. Models are constructed in a way that involves deliberate simplification, or other imaginative modification of reality, (...) in order to make relationships visible or problems tractable. (shrink)

I start by way of clarifying briefly the problem of special divine intervention. Once this is done, I argue that laws of nature are generalizations that derive from the dispositional behaviour of natural kinds. Based on this conception of laws of nature I provide a metaphysical model according to which God can realize acts of special divine providence by way of temporarily changing the dispositions of natural entities. I show that this model does not contradict scientific practice and is consistent (...) with the assumption that the physical realm is causally closed. I then argue that prima facie any putative candidate for an act of God could also be seen as a random event or as indicating that there is something wrong with our formulation of the corresponding law of nature. While there is no sufficient philosophical or scientific reason to prefer one of these models, I argue that there are sufficient and legitimate theological reasons to endorse a framework in which at least the obtaining of some anomic states of affairs is seen as the effect of special divine intervention. Doing so, theology has the hermeneutic resources to uncover a dimension of meaningful reality, which without faith could not be seen. (shrink)
