Diversity Reading List

Publisher's Note: What do blue things have in common? Or electrons? Or planets? Distinct things appear to share properties; but what are properties and what is the best philosophical account of them? A Critical Introduction to Properties introduces different ontological accounts of properties, exploring how their formulation is shaped by the explanatory demands placed upon them. This accessible introduction begins with a discussion of universals, tropes, sets and resemblance classes, the major objections to them and their responses, providing readers with a firm grasp on the competing ontological accounts of what (if anything) grounds similarity and difference. It then explores issues concerning the formulation and justification of property theories such as: how many properties are there? Should we accept a sparse ontology of properties, or an abundant one? Can we make a distinction between intrinsic and extrinsic properties? Do properties have their causal roles necessarily? What is the relationship between properties and other metaphysical phenomena such as causality, laws and modality? These questions get to the heart of why a coherent theory of properties is so important to metaphysics, and to philosophy more generally. By concluding with the question of the ontological status of properties, the reader is introduced to some Carnapian and contemporary themes about the content and methodology of metaphysics. For students looking for an accessible resource and a more comprehensive understanding of contemporary metaphysics, A Critical Introduction to Properties is a valuable starting point.

Abstract:

This paper outlines a defense of hybrid contingentism: that it is contingent which individuals there are, but not contingent what properties there are. Critics pursue two main lines of complaint. First, that the hybrid contingentist’s treatment of haecceitistic properties is metaphysically mysterious, and second, that hybrid contingentism involves an unjustified asymmetry in the associated modal logic. I suggest that these complaints may be too quick, at least in the setting of higher-order metaphysics. It is not at all obvious whether and to what extent we should expect particular "symmetries" across the orders, and so whether (as Williamson (2013) argues) “the default preference is for a uniform metaphysics, on which being is contingent at all orders or none.”

Abstract:

Vetter's Potentiality is an exposition and development of a new account of possibility and necessity, given in terms of potentialities. In this critical notice, I give an outline of some of the key claims of the book. I then raise some issues for the extent to which Vetter's view can accommodate genuine de re modalities, especially those of possible existence and non-existence. 

Publisher's Note: This book develops and defends dispositionalism about modality: the view that metaphysical modality is a matter of the dispositions that objects have. Dispositionalism is an attractive view for actualists about modality, and for anyone who embraces an anti-Humean metaphysics of powers. This book shows in detail how such a view is to be formulated, which challenges it faces, and how they may be met. The metaphysics of potentiality is examined in detail to show that the view meets the three main challenges for a metaphysics of modality: (1) Extensional correctness: providing the right truth-values for statements of possibility and necessity; (2) formal adequacy: providing the right logic for metaphysical modality; and (3) semantic utility: providing a semantics that links ordinary modal language to the metaphysics of modality.
