How ontologically committal is common sense? Is the common-sense philosopher beholden to a florid ontology in which all manner of objects, substances, and processes exist and are as they appear to be to common sense, or can she remain neutral on questions about the existence and nature of many things because common sense is largely non-committal? This chapter explores and tentatively evaluates three different approaches to answering these questions. The first applies standard accounts of ontological commitment to common-sense claims. (...) This leads to the surprising and counter-intuitive result that common sense has metaphysically heavyweight commitments. The second approach emphasizes the superficiality and locality of common-sense claims. On this approach, however, common sense comes out as almost entirely non-committal. The third approach questions the seriousness of ontological commitment as such. If ontological commitment is cheap, it becomes possible both to accept the commitments of common sense at face value and to avoid the counter-intuitive consequences of heavyweight metaphysical commitments.

Quine’s general approach is to treat ontology as a matter of what a theory says there is. This turns ontology into a question of which existential statements are consequences of that theory. This approach is contrasted favourably with the view that takes ontological commitment as a relation to things. However within the broadly Quinean approach we can distinguish different accounts, differing as to the nature of the consequence relation best suited for determining those consequences. It is suggested that Quine’s (...) own narrowly formal account fails. Then a consideration of the necessitation approach championed by Jackson and Lewis shows that it does not do justice to the role of acknowledging consequences in determining rationality. I suggest that an approach which puts a priori consequence as the key relation does a better job. The task of spelling out the nature of a priori consequence is sketched, along with reasons to doubt the adequacy of the double indexing approach to analysing the a priori. The sorts of relations we can stand in to theories which allow us to inherit ontological commitments are touched on with a number of important philosophical strategies for introducing belief-like attitudes which nevertheless avoid ontological commitment.

Terence Horgan's "contextual semantics" is supposed to be a means to avoid unwanted ontological commitments, in particular commitments to non-physical objects, such as institutions, theories and symphonies. The core of contextual semantics is the claim that truth is correct assertibility, and that there are various standards of correct assertibility, the standards of "referential semantics" being only one among others. I am investigating the notions of correct assertibility,assertibility norms and indirect reference. I argue that closer inspection reveals that (...) contextual semantics ultimately amounts – contra Horgan's intentions – to a paraphrase strategy. I defend an ontological commitment to theories and symphonies. (shrink)

This chapter continues the discussion of the issues raised by the chapter 6, focusing on the issue of ontological commitment. The chapter argues that Buridan’s theory of ampliation, reconstructed in terms of quantification with restricted variables, provides a genuine third alternative to the opposing modern views of Quine and “the Meinongians.” Furthermore, the chapter argues that Buridan’s theory thus reconstructed says “all the right things” according to Quine in its object-language; however, it still seems to side with the Meinongians (...) in its meta-language. However, this is just a feature of the reconstruction: “the real Buridan” does not have this distinction, but works out his natural language semantics under conditions of what Tarski described as “semantic closure.”.

Some time ago, Quine asserted that to be is to be value of a variable. This entails that if one wishes to accept any theory as true, we must be committed to the existence of those objects over which we existentially quantify. I suggest instead that we are committed only to the existence of things for which certain intrinsic properties are contingent (those that an object can have independent of the properties that make it a member of a certain kind). (...) Any discourse that involves existential quantification over entities for which those properties can change should be given an objectual interpretation, and these objects are therefore real. In contrast, all discourse that involves existential quantification over objects who have at least some intrinsic properties essentially, which are properties that are not what make them members of a kind, will be given a substitutional interpretation, which does not entail a realist interpretation. This conception of ontological commitment has potential direct consequences in several areas -- the status of fictional characters, the debate about the existence of god, realism about mathematical entities, and so on.

In his article on pre-conventions, Celano presents, what the author calls, the Ontological Commitment Thesis and the Normative Bite Thesis. In this short comment, the author argues that the two theses are together both incompatible with the idea that pre-conventions are facts which have causal powers in human behaviour; also, if the ontological thesis is abandoned, normative determination could not be obtained. In other terms, the author argues that either pre-conventions are part of our causal explanation of human (...) behaviour or pre-conventions are abstract entities able to determine human behaviour normatively. In the first case, pre-conventions lack normative meaning, while in the second pre-conventions cannot integrate our causal explanation of human actions. Tertium non datur. (shrink)

There are two doctrines for which Quine is particularly well known: the doctrine of ontological commitment and the inscrutability thesis—the thesis that reference and quantification are inscrutable. At first glance, the two doctrines are squarely at odds. If there is no fact of the matter as to what our expressions refer to, then it would appear that no determinate commitments can be read off of our best theories. We argue here that the appearance of a clash between the (...) two doctrines is illusory. The reason that there is no real conflict is not simply that in determining our theories’ ontological commitments we naturally rely on our home language but also (and more importantly) that ontological commitment is not intimately tied to objectual quantification and a reference-first approach to language. Or so we will argue. We conclude with a new inscrutability argument which rests on the observation that the notion of objectual quantification, when properly cashed out, deflates. (shrink)

In this paper, I shall assess the ontological commitments of frame-based methods of knowledge representation. Frames decompose concepts into recursive attribute-value structures. The question is: are the attribute values in frames to be interpreted as universal properties or rather as tropes? I shall argue that universals realism and trope theory face similar complications as far as non-terminal values, i.e., values which refer to the determinable properties of objects, are concerned. It is suggested that these complications can be overcome (...) if one is prepared to adopt an ontology of structured complexes. Such an ontology, in turn, is indifferent as to whether attribute values are interpreted as universals or as tropes. (shrink)

In this paper I defend a Quinean view on ontological commitment against some recent challenges. I outline the virtues and limitations of the Quinean approach before considering two different theories. Thomas Hofweber argues that commitment in natural language is ambiguous and that Quine’s canonical notation is incapable of representing the two functions of natural language quantifiers. Truthmaker theorists argue that Quine’s approach is based on a fallacious view of the relation between true sentences and the truthmaking domain (the world). (...) In response I argue that both objections are aimed at a particularly strong version of the Quinean approach, and that rather than abandon it we can use these challenges to understand its true value.

Disagreement over what exists is so fundamental that it tends to hinder or even to block dialogue among disputants. The various controversies between believers and atheists, or realists and nominalists, are only two kinds of examples. Interested in contributing to the intelligibility of the debate on ontology, in 1939 Willard van Orman Quine began a series of works which introduces the notion of ontological commitment and proposes an allegedly objective criterion to identify the exact conditions under which a theoretical (...) discourse signals an assumption of existence. I intend to present the concept of ontological commitment and the Quinean criterion, to expose and evaluate some of the many criticisms to which the criterion has subject and to situate it in the context of Quine’s philosophy. As a product of such analyses, I hope to contribute to the discussion on the application and relevance of the notion of ontological commitment. (shrink)

Actualism is the doctrine that the only things there are, that have being in any sense, are the things that actually exist. In particular, actualism eschews possibilism, the doctrine that there are merely possible objects. It is widely held that one cannot both be an actualist and at the same time take possible world semantics seriously — that is, take it as the basis for a genuine theory of truth for modal languages, or look to it for insight into the (...) modal structure of reality. For possible world semantics, it is supposed, commits one to possibilism. In this paper I take issue with this view. To the contrary, I argue that one can take possible world semantics seriously without any commitment to possible worlds or possibilism and hence remain in full compliance with actualist scruples. Moreover, one can do so without without invoking either "ersatz" worlds or haecceities. (shrink)

The standard account of ontological commitment is quantificational. There are many old and well-chewed-over challenges to the account, but recently Kit Fine added a new challenge. Fine claimed that the ‘‘quantificational account gets the basic logic of ontological commitment wrong’’ and offered an alternative account that used an existence predicate. While Fine’s argument does point to a real lacuna in the standard approach, I show that his own account also gets ‘‘the basic logic of ontological commitment wrong’’. (...) In response, I offer a full quantificational account, using the resources of plural logic, and argue that it leads to a complete theory of natural language ontological commitment. (shrink)

For Quine, the ontological commitments of a discourse are what fall under its (objectual) quantifiers. The recent literature, however, is beginning to move away from this picture. There are direct challenges to Quine's criterion, and there are also attempts to provide alternatives. Azzouni suggests that the ontological commitments of a discourse should be determined by an existence predicate instead. The availability of this alternative forces an adjudication between Qune's criterion and the predicate approach to ontological (...) commitment. I argue that to adjudicate between these criteria for ontological commitment, we need first to adjudicate between criteria for what exists. (shrink)

What are the ontological commitments of a sentence? In this paper I offer an answer from the perspective of the truthmaker theorist that contrasts with the familiar Quinean criterion. I detail some of the benefits of thinking of things this way: they include making the composition debate tractable without appealing to a neo-Carnapian metaontology, making sense of neo-Fregeanism, and dispensing with some otherwise recalcitrant necessary connections.

When we use a directly referential expression to denote an object, do we incur an ontological commitment to that object, as Russell and Barcan Marcus held? Not according to Quine, whose regimented language has only variables as denoting expressions, but no constants to model direct reference. I make a case for a more liberal conception of ontological commitment—more wide-ranging than Quine’s—which allows for commitment to individuals, with an improved logical language of regimentation. The reason for Quine’s prohibition on (...) commitment to individuals, I argue, is that his choice of regimented language is heavily informed by his holist epistemology, in which objects are introduced via a description of their explanatory role. But non-holists can coherently attempt to commit to individuals using directly referential expressions, modelled in a formal language as constants. While holding on to the insight that a logical language is a helpful medium for ontology, I propose instead a more permissive language of regimentation, one expanded to permit the use of constants to record attempts to commit to individuals, which allows us to make sense of non-holist theories with alternative name-based or name-and-variable-based criteria of ontological commitment as well as Quinean theories.

I propose a way of thinking aboout content, and a related way of thinking about ontological commitment. (This is part of a series of four closely related papers. The other three are ‘On Specifying Truth-Conditions’, ‘An Actualist’s Guide to Quantifying In’ and ‘An Account of Possibility’.).

This paper analyses the cognitive image schemas structuring the ontological commitments of dominant conceptions of ethics and economics to show that the content of economics is implicated in conceptions of ethics, and that these conceptions cannot be separated from questions of research and professional ethics. This analysis of the metaphoric structuring of the ontological commitments of ethics and economics is based on an extension of Kuhn's construct sense of 'paradigm' as concrete analogy; and on techniques of (...) metaphoric analysis developed in cognitive linguistics. Analysis of the iconic and schematic representations of the concrete analogies and idealised cognitive models structuring economic and ethical theories expose both shared and conflicting ontological commitments.

This research is aimed at explaining and analyzing the ontological status of semantical objects of religious language. This ontological status concern how every term in religious language refers to an object and how we interpret those terms, whether it represents the object itself or merely its sensual or constructive properties. This finding lies in the disputation between religious realism and non-realism. The results of this research are (1) every believer is exactly a realist because he or she has (...) the ontological commitment to the object of the utterance, but (2) God exists independently from human thought and consciousness, (3) it is possible to put God as the object of intentional and semantic but only represents sensible qualities of the real object, and (4) the meaning of religious language depends on believer's ontological commitment on God's existence.

ABSTRACT The music of the Western world has always had a necessary and more or less committed relationship to arithmetic, geometry, and physics. The article carries out a historical review of this relation, in order to point out some of the philosophical and epistemological issues shared by those disciplines. The path covered starts out with the Greeks and ends with the High Middle Ages, when the principles of disatematic notation are established. The latter, in turn, constitutes the basis for staff notation, that is, the symbolic system typical of Western tradition until the 20th century.

From Parmenides to the present, philosophers have been attracted by characterizations of being as being uttered or utterable, formulated or formulable. But what for Parmenides was presumably a valid co-entailment between antecedently understood concepts reappears in contemporary thought as a proffered explication of what it is to be. Without presuming to discredit Parmenidean views in general, my purpose here is to examine certain members of a modern family of theories of existence that fall into place around Quine’s. Depending on the (...) methodology of explication espoused, the theories in this family are either semantic commentaries on ideal languages, or they are themselves interpreted formalized languages. The former may be called, after Quine, theories of ontological commitment. The theories of the latter sort I wish to consider are called, after Karel Lambert, free logics, i.e., logic systems the singular terms of which are free of existential import. My conclusion about theories of both kinds is that, while unexceptionable on their own terms, from a broader point of view they beg the question of what it is to be. In arguing that these theories thus fail to clarify the concept of existence, I believe I am not so much propounding a new insight as articulating an objection many thinkers have felt in the face of views akin to Quine’s.

Second-order axiomatizations of certain important mathematical theories—such as arithmetic and real analysis—can be shown to be categorical. Categoricity implies semantic completeness, and semantic completeness in turn implies determinacy of truth-value. Second-order axiomatizations are thus appealing to realists as they sometimes seem to offer support for the realist thesis that mathematical statements have determinate truth-values. The status of second-order logic is a controversial issue, however. Worries about ontological commitment have been influential in the debate. Recently, Vann McGee has argued that (...) one can get some of the technical advantages of second-order axiomatizations—categoricity, in particular—while walking free of worries about ontological commitment. In so arguing he appeals to the notion of an open-ended schema—a schema that holds no matter how the language of the relevant theory is extended. Contra McGee, we argue that second-order quantification and open-ended schemas are on a par when it comes to ontological commitment. (shrink)

There are two different ways of understanding the notion of ‘ontological commitment ’. A question about ‘what is said to be’ by a theory or ‘what a theory says there is’ deals with ‘explicit’ commitment ; a question about the ontological costs or preconditions of the truth of a theory concerns ‘implicit’ commitment. I defend a conception of ontological commitment as implicit commitment, and argue that existentially quantified idioms in natural language are implicitly, but not explicitly, committing. (...) I use the distinction between the two kinds of ontological commitment to diagnose a flaw in a widely used argument to the effect that existential quantification is not ontologically committing.

This paper aims at discussing the usage by Davidson as to events of Quine's criterion of ontological commitment. According to Davidson, we are ontologically committed to the existence of events as individuals as we employ literally terms such as ‘Caesar’s death’, for instance. Davidson extends this analysis to actions as well, since actions are human events. One of the consequences of this view is that psychology deals with individual events in a non-lawful way. An alternative view is here proposed, (...) based on a complementary criterion, namely ontological density, according to which from the point of view of a given theory, we can always distinguish between events (or phenomena) and individuals (entities) among the overall occurrences described by the theory. Some consequences of this alternative view of psychology as a science dealing lawfully with general human events are also explored here. (shrink)

"The Ontological Commitments of Feminist Theory," a paper co-sponsored by the Center for Advanced Feminist Studies and the Department of Philosophy, the University of Minnesota, June 1991; and delivered to the Philosophy Department at the University of North Carolina, Chapel Hill, November 1991. A rewritten version of this was delivered at the University of Auckland, New Zealand, June 1993; also at Miami University of Ohio, February 1994.

This paper develops an alternative for (what feminists call) ‘the sex/gender distinction’. I do so in order to avoid certain problematic implications that the distinction underpins. First, the sex/gender distinction paradigmatically holds that some social conditions determine one’s gender (whether one is a woman or a man), and that some biological conditions determine one’s sex (whether one is female or male). Further, sex and gender come apart. Since gender is socially constructed, this implies that women exist mind-dependently, or due to (...) productive human social activities; thus, it should be possible to do away with them just by altering the social conditions on which gender depends. In addition, some feminists take gender to depend on oppressive social conditions. Changing our social environments, then, would not only unwittingly eradicate women; doing away with women should be feminism’s political goal. I argue that both implications are unacceptable. In response, I argue for a view that has ontological commitments which are more congenial to ordinary thinking, and that doesn’t have the goal of eradicating women. (shrink)

Discourse carries thin commitment to objects of a certain sort iff it says or implies that there are such objects. It carries a thick commitment to such objects iff an account of what determines truth-values for its sentences say or implies that there are such objects. This paper presents two model-theoretic semantics for mathematical discourse, one reflecting thick commitment to mathematical objects, the other reflecting only a thin commitment to them. According to the latter view, for example, the semantic role (...) of number-words is not designation but rather the encoding of cardinality-quantifiers. I also present some reasons for preferring this view. (shrink)

According to the familiar Quinean understanding of ontological commitment, (1) one undertakes ontological commitments only via theoretical regimentations, and (2) ontological commitments are to be identified with the domain of a theory’s quantifiers. Jody Azzouni accepts (1), but rejects (2). Azzouni accepts (1) because he believes that no vernacular expression carries ontological commitments. He rejects (2) by locating a theory’s commitments with the extension of an existence predicate. I argue that Azzouni’s two (...) theses undermine each other. If ontological commitments follow from predications of existence, then ontological commitments can be expressed in the vernacular via negative existential sentences. (shrink)

It is persons who are ontologically committed. But a person is not ontologically committed by virtue of his character, his height, his social standing or whatever, but by virtue of the sentences he assents to. Hence we should look to sentences for a criterion of ontological commitment. This is precisely what is done by advocates of what I will call the Referential theory. In this paper I argue that the Referential theory faces serious objections related to the role paraphrase (...) must play in it. I then present a modified Referential theory and go on to discuss certain implications of the modified theory. More precisely, the paper divides up as follows. In §1 I present the Referential theory. In §2 I argue that it is in trouble over paraphrase. In §3 I consider a general objection to the arguments of §2. In §4 I present the modified theory. In §5 I consider the implications of the modified theory for polemic over what there is and for the existence of properties or universals. (shrink)

This chapter discusses ontological commitment to properties, understood as ontological correlates of predicates. We examine the issue in four metaontological settings, beginning with an influential Quinean paradigm on which ontology concerns what there is. We argue that this naturally but not inevitably avoids ontological commitment to properties. Our remaining three settings correspond to the most prominent departures from the Quinean paradigm. Firstly, we enrich the Quinean paradigm with a primitive, non-quantificational notion of existence. Ontology then concerns what (...) exists. We argue that this strengthens the Quinean case against ontological commitment to properties while also newly distinguishing between stronger and weaker forms of nominalism. Secondly, we enrich the Quinean paradigm with the ideology of fundamentality. Ontology then centrally concerns what’s fundamental. We argue that this leaves ontological commitment to properties wide open although Bradleyan regress threatens. Thirdly, we enrich the Quinean paradigm with primitive higher-order quantifiers. Ontology then expands to concern what there higher-order is and what there first-order is. We argue that this naturally but not inevitably incurs ontological commitment to properties. (shrink)

Some forms of analytic reconstructivism take natural language (and common sense at large) to be ontologically opaque: ordinary sentences must be suitably rewritten or paraphrased before questions of ontological commitment may be raised. Other forms of reconstructivism take the commitment of ordinary language at face value, but regard it as metaphysically misleading: common-sense objects exist, but they are not what we normally think they are. This paper is an attempt to clarify and critically assess some common limits of these (...) two reconstructivist strategies. (shrink)

The question of ontological commitment in Plato’s Hippias Major has been important in disputes over the dialogue’s place in the corpus, its meaning, and its authenticity. But this question seems to have been settled—the Hippias Major is not committed to the ‘forms.’ Such an ontological conclusion has been vigorously defended, but its defenses rest on a problematic meta-ontological framework. This paper suggests a more adequate framework and brings more evidence to the evaluation of the question of (...) class='Hi'>ontological commitment in the Hippias Major. It concludes that the dialogue is indeed committed to some kind of form. (shrink)

This paper provides a comparison of three fundamentally different approaches to the issue of ontological commitment. It argues that despite superficial similarities on either side, Buridan’s approach provides an intriguing third alternative to the two commonly recognized modern approaches.
