Metaontology

Neste ensaio, discutem-se cinco questões acerca da existência: 1. É a existência representável em termos de quantificação? 2. É a existência um predicado" real", de primeira ordem? 3. É existir o mesmo que ser? 4. Existe tudo? 5. Qual é a forma lógica de afirmações de existência? São introduzidas e examinadas algumas das mais salientes posições acerca destas questões, em especial a concepção Frege-Russell da existência e diversas concepções recentes neo-Meinongianas. Defendemos as seguintes três teses acerca daquilo que deve ser (...) um bom predicado de existência:(a) um predicado puramente lógico e parcialmente definível em termos do quantificador existencial;(b) invariavelmente um predicado de primeira ordem (dadas certas suposições de partida acerca do universo do discurso);(c) um predicado universal, verdadeiro de tudo e falso de nada.

W. V. Quine was one of the most influential figures of twentieth-century American analytic philosophy. Although he wrote predominantly in English, in Brazil in 1942 he gave a series of lectures on logic and its philosophy in Portuguese, subsequently published as the book O Sentido da Nova Lógica. The book has never before been fully translated into English, and this volume is the first to make its content accessible to Anglophone philosophers. Quine would go on to develop revolutionary ideas about (...) semantic holism and ontology, and this book provides a snapshot of his views on logic and language at a pivotal stage of his intellectual development. The volume also includes an essay on logic which Quine also published in Portuguese, together with an extensive historical-philosophical essay by Frederique Janssen-Lauret. The valuable and previously neglected works first translated in this volume will be essential for scholars of twentieth-century philosophy. (shrink)

This book is an exploration and defense of the coherence of classical theism’s doctrine of divine aseity in the face of the challenge posed by Platonism with respect to abstract objects. A synoptic work in analytic philosophy of religion, the book engages discussions in philosophy of mathematics, philosophy of language, metaphysics, and metaontology. It addresses absolute creationism, non-Platonic realism, fictionalism, neutralism, and alternative logics and semantics, among other topics. The book offers a helpful taxonomy of the wide range of options (...) available to the classical theist for dealing with the challenge of Platonism. It probes in detail the diverse views on the reality of abstract objects and their compatibility with classical theism. It contains a most thorough discussion, rooted in careful exegesis, of the biblical and patristic basis of the doctrine of divine aseity. Finally, it challenges the influential Quinean metaontological theses concerning the way in which we make ontological commitments. (shrink)

A book review of Amie Thomasson's defense of Neo-Carnapianism in her "Ontology Made Easy" (2015, Oxford UP).

Part of Kant’s legacy to Peirce was a lasting conviction that metaphysics is not irredeemable, but can and should be set “on the secure path of a science”. However, Peirce’s “scientific metaphysics”, unlike Kant’s, uses the method of science, i.e., of experience and reasoning; but requires close attention to experience of the most familiar kind rather than the recherché experience needed by the special sciences. This distinctively plausible reconception of what a genuinely scientific metaphysics would be is part of Peirce’s (...) legacy to philosophy today, enabling us to steer clear of both apriorism and of scientism - the Scylla and Charybdis of recent metaphysics.

Quine has called the question, ‘What is there?’ the “ontological question.” But if we call this question by that name, what name shall we use for the question, ‘What are we asking when we ask “What is there?”’? I shall call it ‘the meta-ontological question’. I shall call the attempt to answer the meta-ontological question ‘meta-ontology’ and any proposed answer to it ‘a meta-ontology’. In this essay, I shall briefly sketch a meta-ontology. The meta-ontology I shall present is broadly Quinean. (...) I am, in fact, willing to call it an exposition of Quine’s meta-ontology. (shrink)

The view that metaphysics is a waste of time appears to be gaining in popularity with every passing day. It is held openly by many scientists and even by many philosophers. I argue here that this is a consequence of the way metaphysics is often done, the futility of a certain approach to it, and not a reason to suppose that there is no useful knowledge to be acquired in metaphysics.

Inspired in Quine's well known slogans “To be is to be the value of a variable” and "No entity without identity", we provide a way of enabling that non-individual entities (as characterized in the text) can also be values of variables of an adequate "regimented" language, once we consider a possible meaning of the background theory Quine reports to ground his view. In doing that, we show that there may exist also entities without identity, and emphasize the importance of paying (...) attention to the metalanguage of scientific theories, for they may be also fundamental in determining the theory's ontological commitment.

The concepts of particular and universal have grown so familiar that their significance has become difficult to discern, like coins that have been passed back and forth too many times, worn smooth so their values can no longer be read. On the Genealogy of Universals seeks to overcome our sense of over-familiarity with these concepts by providing a case study of their evolution during the late nineteenth century and early twentieth century, a study that shows how the history of these (...) concepts is bound up with the origins and development of analytic philosophy itself. Understanding how these concepts were taken up, transfigured, and given up by the early analytic philosophers, enables us to recover and reanimate the debate amongst them that otherwise remains Delphic. This book begins from the early, originating texts of analytic philosophy that have hitherto baffled commentators, including Moore's early papers, and engages afresh with the neglected contributions of philosophical figures that historians of analytic philosophy have mostly since forgotten, including Stout and Whitehead. This sheds new light upon the relationships of Moore to Russell, Russell to Wittgenstein, and Wittgenstein to Ramsey. (shrink)

Truthmaker theorists hold that propositions about higher-level entities (e.g. the proposition that there is a heap of sand) are often made true by lower-level entities (e.g. by facts about the configuration of fundamental particles). This generates a problem: what should we say about these higher-level entities? On the one hand, they must exist (since there are true propositions about them), on the other hand, it seems that they are completely superfluous and should be banished for reasons of ontological parsimony. Some (...) truthmaker theorists—most prominently David Armstrong—have tried to solve this puzzle by arguing that these entities are ‘an ontological free lunch’, i.e. real existents that are still ‘no addition of being’. This answer is prima facie attractive, but I argue in this paper that the standard approaches to truthmaking—modal theories and grounding theories—are unable to vindicate the doctrine of the ontological free lunch, and thus fail to solve the problem of higher-level entities. Fortunately, there is a non-standard account of truthmaking available, the reductive explanation account, which succeeds where the standard approaches fail. (shrink)

I argue that metaphysical views of material objects should be understood as 'packages', rather than individual claims, where the other parts of the package include how the theory addresses 'recalcitant data', and that when the packages meet certain general desiderata - which all of the currently competing views *can* meet - there is nothing in the world that could make one of the theories true as opposed to any of the others.

Some relations - like supervenience and composition - can appear very much like identity. Sometimes, the relata differ only in modal, or modally-involved features. Yet, in some cases, we judge the pairs to be identical (water/H2O; Hesperus/Phosphorus), while in others, many judge one of the weaker relations to hold (c-fiber firing/pain; statues/lumps). Given the seemingly same actual properties these pairs have, what can justify us in sometimes believing identity is the relation, and sometimes something weaker? I argue that it can (...) only be knowledge of differences of individuative criteria that we know a priori because they are built into the meanings of the words/concepts involved. Possible metaphysical conclusions are considered. (shrink)

When is there no fact of the matter about a metaphysical question? When multiple candidate meanings are equally eligible, in David Lewis's sense, and fit equally well with ordinary usage. Thus given certain ontological schemes, there is no fact of the matter whether the criterion of personal identity over time is physical or psychological. But given other ontological schemes there is a fact of the matter; and there is a fact of the matter about which ontological scheme is correct.

Four- Dimensionalism defends the thesis that the material world is composed of temporal as well as spatial parts. This defense includes a novel account of persistence over time, new arguments in favour of the four-dimensional ontology, and responses to the challenges four- dimensionalism faces." "Theodore Sider pays particular attention to the philosophy of time, including a strong series of arguments against presentism, the thesis that only the present is real. Arguments offered in favour of four- dimensionalism include novel arguments based (...) on time travel, the debate between spacetime substantivalists and relationalists, and vagueness. Also included is a comprehensive discussion of the paradoxes of coinciding material objects, and a novel resolution of those paradoxes based on temporal counterpart theory. In conclusion Sider replies to prominent objections to four- dimensionalism, including discussion of the problem of the rotating homogenous disk. (shrink)

Some commitments at the interface of semantics and ontology, such as numbers or symphonies, tend to appear problematic. The scorekeeping approach to semantics introduces contextually shifting parameters that allow for construal of truth as indirect correspondence. Meinong did recognize diversity and richness that is made possible by the non-reductionist engagement of the scorekeeping approach. Because of his commitment to the deep presupposition of direct correspondence construal of truth though, Meinong had to interpret richness of normative discursive scorekeeping commitments as richness (...) of ontological strata, features and engagements. Once as Meinong recognizes the construal of truth as indirect correspondence, many problems related to his objects dissolve, naturally placing his scorekeeping discovery into discursive normative setting. A translation of Meinongian objects into discursive scores confirms that his discovery aims at these indeed, which is obscured by his sticking to the construal of truth as direct correspondence.

There is a charge sometimes made in metaphysics that particular commitments are ‘hypothetical’, ‘dubious’ or ‘suspicious’. There have been two analyses given of what this consists in—due to Crisp (2007) and Cameron (2011). The aim of this paper is to reject both analyses and thereby show that there is no obvious way to press the objection against said commitments that they are ‘dubious’ and objectionable. Later in the paper I consider another account of what it might be to be ‘dubious’, (...) and argue that this too fails. I use Bigelow's (1996) Lucretian properties as a vehicle for the discussions of dubiousness that follow. As a consequence, the paper ends up offering a partial defense of Lucretianism. (shrink)

In recent years, it has become common to defend science against charges of bias against the supernatural by explaining that science must remain methodologically natural but does not assume metaphysical naturalism. While such a response is correct, some details about the distinction between methodological naturalism and ontological or metaphysical naturalism have been lacking, as has a clear understanding of the distinction between the methodological restriction of science to natural explanations and naturalistic claims about the scope of those methods. We still (...) require an account of the natural that explains well why science is restricted to giving naturalistic methods, and why the pursuit of natural explanations is not tantamount to the assumption that only natural causes exist. I suggest that the distinguishing characteristics of the natural are not metaphysical at all but broadly epistemological, concerning goals of intersubjectivity and predictability. I argue that by focusing on naturalistic goals we can better explain why the pursuit of natural explanations need not presume any purely natural metaphysics. But I also suggest that the adoption of natural methods is not entirely metaphysically neutral, as it is associated with values that may be more closely associated with some metaphysical views than others.

While fights about ontology rage on in the ring, there’s long been a suspicion whispered in certain corners of the stadium that some of the fights aren’t real. Granted the disputants all think they are really disagreeing—it’s not the sincerity of the serious ontologists that’s in question, but rather their judgment that they are engaged in a real debate about genuine issues of substance.

My wife and I and our three children may stand in various relations: being a family, being a basketball team, and so on. I show that Frege's doctrine of existence, when coupled with this simple point, easily solves the problem of material constitution and blocks the overdetermination argument for eliminativism. It does all this work while providing a plausible and clear reductionistic account of material objects. These seem to be very good reasons for accepting Frege's doctrine of existence.

The topic of this book is material objects. Like most interesting concepts, the concept of a material object is one without precise boundaries.

An introduction to analytic ontology. Part 1 deals with the question, What is ontology?, focusing on (i) the interplay between ontological and broadly metaphysical concerns, and (ii) the difference between material ontology and formal ontology. Part 2 deals with the question, How is ontology done?, focusing on (i) the delicate interplay between ontology and truth-making (or: between meaning and existence), and (ii) the differences between revolutionary vs. hermeneutic, prescriptive vs. descriptive, and absolute vs. relative approaches to ontology. Part 3 surveys (...) the state of the art in a number of areas, both in material ontology (e.g., the problem of universals, the status of objects and events, the ontology of mathematics, of the physical sciences, of the social sciences) and in formal ontology (identity, ontological dependence, part-whole relations).

In this paper, I will defend the claim that there are three existence properties: the second-order property of being instantiated, a substantive first-order property (or better a group of such properties) and a formal, hence universal, first-order property. I will first try to show what these properties are and why we need all of them for ontological purposes. Moreover, I will try to show why a Meinong-like option that positively endorses both the former and the latter first-order property is the (...) correct view in ontology. Finally, I will add some methodological remarks as to why this debate has to be articulated from the point of view of reality, i.e., by speaking of properties, rather than from the point of view of language, i.e., by speaking of predicates (for such properties).

On reading the last sentence, did you interpret me as saying falsely that everything — everything in the entire universe — was packed into my carry-on baggage? Probably not. In ordinary language, ‘everything’ and other quantifiers (‘something’, ‘nothing’, ‘every dog’, ...) often carry a tacit restriction to a domain of contextually relevant objects, such as the things that I need to take with me on my journey. Thus a sentence of the form ‘Everything Fs’ is true as uttered in a (...) context C if and only if everything that is relevant in C satisfies the predicate ‘F’; ‘everything’ ranges just over the contextually relevant things. Such generality is restricted in a context-relative way. (shrink)

Our study aims to deal with different and similar conditions between Ghazzali and Kant, as characters at whom can show two different thinking form and two different cultural structure in their thoughts, in the context of the same subject. The article investigates the stages of these two thinkers approaches to the topic of transcendental dialectic and tries to display that why and how two different cultural worlds incline to this subject.

This paper argues for a certain kind of anti-metaphysicalism about the temporal ontology debate, i.e., the debate between presentists and eternalists over the existence of past and future objects. Three different kinds of anti-metaphysicalism are defined—namely, non-factualism, physical-empiricism, and trivialism. The paper argues for the disjunction of these three views. It is then argued that trivialism is false, so that either non-factualism or physical-empiricism is true. Finally, the paper ends with a discussion of whether we should endorse non-factualism or physical-empiricism. (...) An initial reason is provided for thinking that non-factualism might be true, but in the end, the paper leaves this question open. The paper also argues against a certain kind of necessitarianism about the temporal ontology debate; but this isn't an extra job—the falsity of this necessitarian view falls out of the other arguments as a sort of corollary.

In this paper, I argue for a new way of characterizing ontological emergence. I appeal to recent discussions in meta-ontology regarding fundamentality and dependence, and show how emergence can be simply and straightforwardly characterized using these notions. I then argue that many of the standard problems for emergence do not apply to this account: given a clearly specified meta-ontological background, emergence becomes much easier to explicate. If my arguments are successful, they show both a helpful way of thinking about emergence (...) and the potential utility of discussions in meta-ontology when applied to first-order metaphysics.

I here investigate whether there is any version of the principle of charity both strong enough to conflict with an error-theoretic version of nominalism (EN) about abstract objects, and supported by the considerations adduced in favour of interpretive charity in the literature. I argue that in order to be strong enough, the principle, which I call (Charity), would have to read, “For all expressions e, an acceptable interpretation must make true a sufficiently high ratio of accepted sentences containing e”. I (...) next consider arguments based on Davidson's intuitive cases for interpretive charity, the reliability of perceptual beliefs, and the reliability of “non-abstractive inference modes”, and conclude that none support (Charity). I then propose a diagnosis of the view that there must be some universal principle of charity ruling out (EN). Finally, I present a reason to think (Charity) is false, namely, that it seems to exclude the possibility of such disagreements as that between nominalists and realists. (shrink)
