As we understand them, dispositions are relatively uncontroversial 'predicatory' properties had by objects disposed in certain ways. By contrast, powers are hypothetical 'ontic' properties posited in order to explain dispositional behaviour. Chapter 1 outlines this distinction in more detail. Chapter 2 offers a summary of the issues surrounding analysis of dispositions and various strategies in contemporary literature to address them, including one of our own. Chapter 3 describes some of the important questions facing the metaphysics of powers including why they're worth positing, and how they might metaphysically explain laws of nature and modality. This title is also available as Open Access on Cambridge Core.
This Element provides an opinionated introduction to the metaphysics of laws of nature. The first section distinguishes between scientific and philosophical questions about laws and describes some criteria for a philosophical account of laws. Subsequent sections explore the leading philosophical theories in detail, reviewing the most influential arguments in the literature. The final few sections assess the state of the field and suggest avenues for future research.
Truthmaking is the metaphysical exploration of the idea that what is true depends upon what exists. Truthmaker theorists argue about what the truthmaking relation involves, which truths require truthmakers, and what those truthmakers are. This Element covers the dominant views on these core issues in truthmaking. It also explores some key metaphysical topics and debates that are usefully approached by employing the tools of truthmaker theory: the debate between presentists and eternalists over the existence of entities from the past, and the debate between actualists and possibilists over merely possible states of affairs. In the final section, the Element explores how to think about truthmakers for truths involving social constructions.
This Element examines the contemporary literature on essence in connection with the traditional question whether essence lies within or without our world. Section 1 understands this question in terms of a certain distinction, the distinction between active and latent facts. Section 2 steps back to investigate the connections between essence and other philosophical concepts. Section 3 brings the results of this investigation to bear on the traditional question, sketching an argument from the premise that essentialist facts are explained by the origins of things to the conclusion that such facts are active.
Substance has long been one of the key categories in metaphysics. This Element focuses on contemporary work on substance, and in particular on contemporary substance ontologies, metaphysical systems in which substance is one of the fundamental categories and individual substances are among the basic building blocks of reality. The topics discussed include the different metaphysical roles which substances have been tasked with playing; different critieria of substancehood (accounts of what is it to be a substance); arguments for and against the existence of substances; and different accounts of which entities, if any, count as substances.
Identity criteria are powerful tools for the metaphysician. They tell us when items are identical or distinct. Some varieties of identity criteria also try to explain in virtue of what items are identical or distinct. This Element has two objectives: to discuss formulations of identity criteria and to take a closer look at one notorious criterion of object identity, Leibniz's Law. The first section concerns the form of identity criteria. The second section concerns the better-regarded half of Leibniz's Law, the indiscernibility of identicals. The third section turns to the more controversial half of Leibniz's Law, the identity of indiscernibles. The author considers alternatives to Leibniz's Law as well as the possibility that there are no adequate identity criteria to be found.
Persistence realism is the view that ordinary sentences that we think and utter about persisting objects are often true. Persistence realism involves both a semantic claim, about what it would take for those sentences to be true, and an ontological claim about the way things are. According to persistence realism, given what it would take for persistence sentences to be true, and given the ontology of our world, often such sentences are true. According to persistence error-theory, they are not. This Element considers several different views about the conditions under which those sentences are true. It argues for a view on which it is relatively easy to vindicate persistence realism, because all it takes is for the world to be the way it seems to us. Thereby it argues for the view that relations of numerical identity, or of being-part-of-the-same-object, are neither necessary nor sufficient for persistence realism.
Although the subject matter of this Element is properties, do not expect in-depth introductions to the various views on properties 'on the market'. Instead, here that subject matter is treated meta-philosophically. Rather than ask and try to answer a question like do properties exist? this Element asks what reasons one might have for thinking that properties exist (what problem properties, if they exist, are there to solve), what counts as solving that (or those) problems (including what counts as 'a property'), as well as how we ought to proceed when trying to find out if properties exist (by which method this ought to be decided). As it turns out, these questions and their answers are all intricately intertwined. Theory comparison and theory evaluation is in other words (and perhaps not that surprisingly) tricky. Do properties exist? After reading this Element all we can say is therefore this: that depends.
Minimally, metaphysical realists hold that there exist some mind-independent entities. Metaphysical realists also (tend to) hold that we can speak meaningfully or truthfully about mind-independent entities. Those who reject metaphysical realism deny one or more of these commitments. This Element aims to introduce the reader to the core commitments of metaphysical realism and to illustrate how these commitments have changed over time by surveying some of the main families of views that realism has been contrasted with: such as (radical) scepticism, idealism, and anti-realism.
Philosophical thinking about time is characterised by tensions between competing conceptions. Different sources of evidence yield different conclusions about it. Common sense suggests there is an objective present, and that time is dynamic. Science recognises neither feature. This Element examines McTaggart's argument for the unreality of time, which epitomises this tension, showing how it gave rise to the A-theory/B-theory debate. Each theory is in tension with either ordinary or scientific thinking, so must accommodate the competing conception. Reconciling the A-theory with science does not look promising. Prospects look better for the B-theory's attempt to accommodate ordinary thinking about time.
This Element is a survey of central topics in the metaphysics of material objects. The topics are grouped into four problem spaces. The first concerns how an object's parts are related to the object's existence and to the object's nature, or essence. The second concerns how an object persists through time, how an object is located in spacetime, and how an object changes. The third concerns paradoxes about objects, including paradoxes of coincidence, paradoxes of fission, and the problem of the many. The fourth concerns views with radical consequences regarding the existence of composite material objects, including mereological nihilism, ontological anti-realism, and deflationism.
Historically, philosophical discussions of relations have featured chiefly as afterthoughts, loose ends to be addressed only after coming to terms with more important and pressing metaphysical issues. F. H. Bradley stands out as an exception. Understanding Bradley's views on relations and their significance today requires an appreciation of the alternatives, which in turn requires an understanding of how relations have traditionally been classified and how philosophers have struggled to capture their nature and their ontological standing. Positions on these topics range from the rejection of relations altogether, to their being awarded the status as grounds for everything else, to various intermediary positions along this spectrum. Love them, hate them, or merely tolerate them, no philosopher engaged in ontologically serious metaphysics can afford to ignore relations.
