In the ‘ordinary business of life’, everyone makes claims about what there is. For instance, we say things like: ‘There are some beautiful chairs in my favourite furniture shop’. Within the context of philosophical debate, some philosophers also make claims about what there is. For instance, some ontologists claim that there are chairs; other ontologists claim that there are no chairs. What is the relation between ontologists’ philosophical claims about what there is and ordinary claims about what there is? According to Cian Dorr, ontologists’ claims and denials of existence belong to ‘a sort of professional jargon’. Dorr claims, for example, that ‘There are prime numbers between 20 and 30’ can be used superficially or used fundamentally. Ordinary uses of are superficial: we use the sentence to assert a boring, well-known truth. But in the ontology room, is used fundamentally, to assert that numbers are ‘part of the ultimate furniture of reality’: and this is a substantial metaphysical doctrine, not a boring truth. In this paper, we will show that none of Dorr’s arguments for these claims succeeds.

Thomas Hofweber argues that the thesis of direct reference is incompatible with physicalism, the claim that the nonphysical supervenes on the physical. According to Hofweber, direct reference implies that some physical objects have object-dependent properties, such as being Jones’s brother, which depend on particular objects for their existence and identity. Hofweber contends that if some physical objects have object-dependent properties, then Local-Local Supervenience (the physicalist doctrine on which he concentrates) fails. In this note, we argue that Hofweber has failed to show that the possession by physical objects of object-dependent properties implies the falsity of Local-Local Supervenience.

Many contemporary philosophers rate error theories poorly. We identify the arguments these philosophers invoke, and expose their deficiencies. We thereby show that the prospects for error theory have been systematically underestimated. By undermining general arguments against all error theories, we leave it open whether any more particular arguments against particular error theories are more successful. The merits of error theories need to be settled on a case-by-case basis: there is no good general argument against error theories.

Many philosophers employ an intellectual division of labour. Philosophy tells us what the truth conditions of various philosophically interesting sentences are. For example, atomic sentences containing numerals are sentences containing singular terms putatively referring to numbers; sentences about what could be are sentences quantifying over possible worlds and so on. Some discipline outside of philosophy tells us that certain of these sentences are true. The purported result is that such philosophically controversial entities as numbers and possible worlds have been shown to exist. I criticize this ‘twin-track strategy’ and try to show that the two components conflict rather than complement each other

What is required for you to know what a certain property is? And what is required for you to have the concept of that property? Hume held that a person who has never tasted a pineapple cannot know what the property tasting like a pineapple is. He also thought that this person cannot have the corresponding concept. A subsequent tradition in empiricism generalises these claims at least to all the so-called "secondary qualities." I will argue that this tradition is mistaken. I will argue that there is no more of a philosophically significant connection between the property tasting like a pineapple and your taste experiences of pineapples than there is between the property having a mass and your tactile experiences when lifting objects. Likewise with respect to the corresponding concepts.

David Lewis’s genuine modal realism is a controversial thesis in modal metaphysics. Charles Chihara and Ross Cameron have each argued that Lewis’s defence of his thesis involves his committing serious methodological errors; in particular, that his replies to two well-known and important objections are question-begging. Scott Shalkowski has further argued that Lewis’s attempt to analyse modal talk in non-modal terms is viciously circular. This paper considers the methodology which Lewis uses to argue for his thesis, and the paper tries to show that it is guilty of no methodological errors.

Do numbers exist? Do properties? Do possible worlds? Do fictional characters? Many metaphysicians spend time and effort trying to answer these and other questions about the existence of various entities. These inquiries have recently encountered opposition: a group of philosophers, drawing inspiration from Aristotle, have argued that many or all of the existence questions debated by metaphysicians can be answered trivially, and so are not worth debating. Our task is to defend existence questions from the neo-Aristotelians' attacks.

This paper concerns an issue in the metaphysics of properties. The issue is: what are physical properties? What distinguishes physical properties from all other properties? My conclusions will be ‘downbeat’. I will argue that some major recent approaches to this issue prove unsatisfactory, and that the issue is much more intractable than has widely been supposed. The moral I draw is that there is no principled and well‐defined distinction between physical properties and all other properties, and accordingly certain programmes in metaphysics should be abandoned because they mistakenly assume that there is such a distinction.

Animalism is the theory that we are animals: in other words, that each of us is numerically identical to an animal. An alternative theory maintains that we are not animals but that each of us is constituted by an animal. Call this alternative theory neo-Lockean constitutionalism or Lockeanism for short. Stephan Blatti (2012) offers to advance the debate between animalism and Lockeanism by providing a new argument for animalism. In this note, we present our own objection to Blatti's argument, and argue that Carl Gillett's earlier reply misses the fundamental problem. We also use Blatti's argument to illustrate a common methodological error, namely, uncritical deference to best theories from other disciplines

The basic idea of Maudlin's superb book is methodological: ‘metaphysics, insofar as it is concerned with the natural world, can do no better than to reflect on physics. Physical theories provide us with the best handle we have on what there is, and the philosopher's proper task is the interpretation and elucidation of those theories. In particular, when choosing the fundamental posits of one's ontology, one must look to scientific practice rather than to philosophical prejudice’ .The apparently diverse topics covered by the book's six chapters are united in bearing out this basic idea. They do so with considerable care and sophistication. The chapters also champion a campaign against David Lewis's thesis of Humean Supervenience. Lewis's thesis says that everything actual supervenes on the distribution of intrinsic qualities across points in space-time.Chapter 1 claims that laws of …
