Externalism about knowledge commits one to a modest form of contextualism: whether one knows depends (or may depend) on circumstances (context) of which one has no knowledge. Such modest contextualism requires the rejection of the KK Principle (If S knows that P, then S knows that S knows that P) - something most people would want to reject anyway - but it does not require (though it is compatible with) a rejection of closure. Radical contextualism, on (...) the other hand, goes a step farther and relativizes knowledge not just to the circumstances of the knower, but to the circumstances of the person attributing knowledge. I reject this more radical form of contextualism and suggest that it confuses (or that it can, at least, be avoided by carefully distinguishing) the relativity in what S is said to know from the relativity in whether S knows what S is said to know.

A number of virtue epistemologists endorse the following thesis: Knowledge is true belief resulting from intellectual virtue, where Ss true belief results from intellectual virtue just in case S believes the truth because S is intellectually virtuous. This thesis commits one to a sort of contextualism about knowledge attributions. This is because, in general, sentences of the form X occurred because Y occurred require a contextualist treatment. This sort of contextualism is contrasted with more familiar versions. It (...) is argued that the position: (a) yields a better solution to the lottery problem, and (b) may be grounded in a more general theory of virtue and credit. (shrink)

This paper raises and then discusses a puzzle concerning the ontological commitments of mathematical principles. The main focus here is Hume's Principle—a statement that, embedded in second-order logic, allows for a deduction of the second-order Peano axioms. The puzzle aims to put pressure on so-called epistemic rejectionism, a position that rejects the analytic status of Hume's Principle. The upshot will be to elicit a new and very basic disagreement between epistemic rejectionism and the neo-Fregeans, defenders of the analytic status (...) of Hume's Principle, which will provide a new angle from which properly to assess and re-evaluate the current debate.

I argue that a certain kind of naturalist approach to social ontology is likely to be both philosophically fruitful and relevant to empirical social science. The kind of naturalism I employ might be called contextualism, which emphasizes the constant presence of assumed background knowledge, is suspicious of general inference rules and all or nothing claims about the ontology of the social sciences, and argues that Quine’s quantificational criterion for ontological commitment has to be supplemented with local (...) interpretations and arguments about what specific social science research is committed to. I look at three case studies employing this perspective, one on agent based models and individualism, a second on the reality of social class, and a third on the reality of race. In all three cases work is first needed to clarifying what empirical social science is claiming, what ontology or ontologies it seems to presuppose, and then description of the kinds of evidence that supports its commitments.

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 note refutes P. Ebert’s argument against Epistemic Rejectionism.

The Cartesian thinking self may seem indisputably real. But if it is real, then so thinking, which would undercut mental fictionalism. Thus, in defense of mental fictionalism, this paper argues for fictionalism about the thinking self. In short form, the argument is: (1) If I exist outside of fiction, then I am identical to (some part of/) this biomass [= my body]. (2) If I die at t, I cease to exist at t. (3) If I die at t, (...) no part of this biomass ceases to exist at t. (4) Therefore, no part of this biomass is identical to me. [From (2), (3)] (5) Therefore, I do not exist outside of fiction. [From (4), (1)] One reply to the argument is that the self is an aggregate of electricity in the brain which disperses upon death. The rejoinder is that this, at best, describes the thoughts realized in the brain, and not the subject who thinks the thoughts. A second objection stresses the undeniable sense that the thinking self has a location. In reply, the extended thought-experiment from Dennett’s “Where Am I?” is used to show that the sense of self-location may well be illusory. (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 discusses two interrelated questions about ontological commitment in the thought of Gregory of Rimini (d. 1358), questions having to do with both hylomorphic composites of matter and substantial form, and with complexe significabilia that typically obtain in cases of substance–accident composition. The first question is that of the existence of real relations: neither hylomorphic composites nor complexe significabilia require real relations tying their various co-located components together. The second is that of the reducibility of such (...) wholes to the sum of their parts: neither hylomorphic composites nor complexe significabilia are anything other than their co-located parts. And all such items can be disunited merely by a divine volition, requiring nothing extramental added to the ontology, and no change in position. (shrink)

Tobias Rosefeldt argues that in order to reconcile a physics-based fundamental ontology with the ontological implications of our everyday utterances, philosophers should pursue a ‘linguistics-based conciliatory’ strategy: They should refer to the results of linguistic research in order to avoid ontological commitment to problematic entities. Whereas Rosefeldt is not an advocate of radical forms of naturalized metaphysics, his argument is driven by the motivation behind pleas for a naturalization of the discipline. I claim that although there is (...) a need for reconciliation, Rosefeldt’s favored account falls short of this goal. More generally, I argue that so-called ‘conciliatory accounts’ fail to do justice to the motivation that necessitated them in the first place, as the role they assign to analyses of everyday speech in search of ontological commitments is at odds with said motivation. ‘Conciliatory accounts’, hence, sit uneasily between radically naturalistic and traditional armchair approaches to metaphysics.

Contemporary logicians sometimes discuss questions like ‘What criterion is there for deciding whether a portion of language or a theory is committed to the existence of anything?’, ‘Does mathematics require us to countenance or tolerate abstract entities?’. In the course of these discussions ancient problems about universals reappear in a new dress. Quine, for one, would agree that it is not by our use of general terms that we commit ourselves to the existence of anything, for general terms like (...) ‘red’ and ‘five’ are not names. Nor does the use of names commit one to corresponding entities, for we sometimes use a name non–designatively. “Names,” as Quine says, “are in fact altogether immaterial to the onto–logical issue.” Quine argues that there is only one way in which we can find out what entities a theory commits us to. Given that the theory is expressed in the symbolism of quantification theory, we discover what entities the theory is committed to by examining what entities have to be values of our bound variables if the statements made in the theory are to be true. “To be is purely and simply to be the value of a variable”. I want to argue in this paper that Quine’s criterion of ontological commitment cannot distinguish genuine from bogus ontological commitment and is therefore inadequate. (shrink)

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.

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.

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.

This is a slightly opinionated review of three main factions in metaontology: Quineans, Carnapians, and Meinongians. Emphasis is given to the last camp, as the metaontological aspect of Meinongianism has been underappreciated. The final section then offers some general remarks about the legitimacy of ontology, touching on ideas I have developed in other publications.

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)

Recent debates about mathematical ontology are guided by the view that Platonism's prospects depend on mathematics' explanatory role in science. If mathematics plays an explanatory role, and in the right kind of way, this carries ontological commitment to mathematical objects. Conversely, the assumption goes, if mathematics merely plays a representational role then our world-oriented uses of mathematics fail to commit us to mathematical objects. I argue that it is a mistake to think that mathematical representation is necessarily (...) ontologically innocent and that there is an argument from mathematics' representational capacity to Platonism. Given that it is common ground between the Platonist and nominalist that mathematics plays a representational role in science, this representationalist argument is to be preferred over the explanatory, or enhanced, indispensability argument.

George Boolos's employment of plurals to give an ontologically innocent interpretation of monadic higher‐order quantification continues and extends a minority tradition in thinking about quantification and ontological commitment. An especially prominent member of that tradition is Stanislaw Leśniewski, and shall first draw attention to this work and its relation to that of Boolos. Secondly I shall stand up briefly for plurals as logically respectable expressions, while noting their limitations in offering ontologically deflationary accounts of higher‐order quantification. Thirdly (...) I shall focus on the key idea of ontological commitment and investigate its connection with the idea of truth‐making. Fourthly I shall consider how different interpretations of quantification may sideline Boolos's work, but finally I shall largely support his analysis of quantification involving nominal expressions, while arguing, in the spirit of Arthur Prior, that non‐nominal quantification is non‐committing.

We argue that the causal theory of memory and the simulation theory of memory are not as straightforwardly incompatible as they are usually taken to be. Following a brief review of the theories, we describe alternative normative and descriptive perspectives on memory, arguing that the causal theory aligns better with the normative perspective and the simulation theory with the descriptive perspective. Taking explanatory contextualism about perception as our starting point, we then develop a form of explanatory contextualism (...) about memory, arguing that, depending on the context in which we find ourselves, either the normative perspective or the descriptive perspective may be appropriate. It follows that, while the causal theory and the simulation theory cannot both be right with respect to a given perspective, and while it is necessary to choose one perspective or the other in a given context, there an important sense in which we need not choose between causalism and simulationism. We conclude by differentiating our position from and critiquing a related position developed by Craver (2020) and defending our position against objections. (shrink)

In recent times, there has been a surge of interest in, and enthusiasm for, contextualist views about prudential discourse — thought and talk about what has prudential value or contributes to someone’s well-being. In this paper I examine and reject two cases for radical forms of prudential contextualism, proposed by Anna Alexandrova and Steve Campbell. Alexandrova holds that the semantic content of terms like ‘well-being’ and ‘doing well’ varies across contexts. Campbell proposes that there are plural prudential (...) concepts at play in prudential discourse (and in philosophical reflection upon such discourse) and that we find evidence of this in the conflicting commitments of prudential discourse. ​The negative aim of the paper is to show that Alexandrova and Campbell have not given us a good case for ambitious forms of contextualism about prudential discourse. The positive aim of the paper is to provide alternative, aspectualist, explanations of the features of prudential discourse that their discussions highlight. (shrink)

Nietzsche's views on knowledge have been interpreted in at least three incompatible ways - as transcendental, naturalistic or proto-deconstructionist. While the first two share a commitment to the possibility of objective truth, the third reading denies this by highlighting Nietzsche's claims about the necessarily falsifying character of human knowledge (his so-called error theory). This paper examines the ways in which his work can be construed as seeking ways of overcoming the strict opposition between naturalism and transcendental philosophy whilst (...) fully taking into account the error theory (interpreted non-literally, as a hyperbolic warning against uncritical forms of realism). In doing so, it clarifies the nature of Nietzsche's ontological commitments, both in the early and the later work, and shows that his relation to transcendental idealism is more subtle than is allowed by naturalistic interpreters while conversely accounting for the impossibility of conceiving the conditions of the possibility of knowledge as genuinely a priori.

A work of music is repeatable in the following sense: it can be multiply performed or played in different places at the same time, and each such datable, locatable performance or playing is an occurrence of it: an item in which the work itself is somehow present, and which thereby makes the work manifest to an audience. As I see it, the central challenge in the ontology of musical works is to come up with an ontological proposal (i.e. an (...) account of what sort of thing a work of music is) which enables us to explain what such repeatability consists in, whilst doing maximal justice to the way in which we conceive of musical works in our reflective critical and appreciative practice. To this end, many have found it tempting to defend some version or other of the type-token theory : the thesis that a work is a type and its occurrences are its tokens. Much of the early debate prompted by the publication of Jerrold Levinson's seminal 'What a Musical Work Is' in 1980 has taken the type-token theory for granted, choosing to focus on how musical works, qua types, are individuated. (A key question here has been whether we should hold, with the sonicist , that works are identical just in case they sound exactly alike; or whether we should agree with Levinson's contextualist thesis that exact sound-alikes are distinct, if composed in distinct musico-historical contexts.) More recently, however, the type-token theory itself has been put under pressure, and alternatives have been suggested. So, e.g. Gregory Currie and David Davies have held versions of the thesis that musical works (and artworks generally) are acts of composition, whilst Guy Rohrbaugh has recommended that we think more innovatively about our metaphysical categories, and treat musical works (along with all repeatable artworks) as historical individuals . Historical individuals, like particular substances, come into and go out of existence, could have been somewhat different than they are, and can change through time; but such items, unlike particular substances, are nonetheless capable of having occurrences. In the last few years, ontologists of music have also stepped back to consider the very nature of their enterprise. In particular, a debate has ensued concerning the cogency of ontological proposals (such as those of Nelson Goodman, Nicholas Wolterstorff and Julian Dodd) that are substantially revisionary of our folk concept of a work of music. Amie Thomasson, David Davies and Andrew Kania occupy, to a greater or lesser degree, the descriptivist standpoint, according to which such revisionary ontologies are misconceived. The debate between revisionists and descriptivists in the ontology of music – if prosecuted against the backdrop of an awareness of developments in meta-ontology more generally – is a particularly fertile area in the philosophy of music at present. Author Recommends Wollheim, Richard. Art and its Objects . 2nd ed. Cambridge: Cambridge University Press, 1980. This seminal study nicely introduces and motivates the type-token theory, and in the course of doing so, helpfully, although perhaps contentiously, distinguishes types from both sets and properties. Wollheim's treatment was to a large part responsible for stimulating the subsequent debate as to the ontological nature of musical works. Levinson, Jerrold. 'What a Musical Work Is.' Journal of Philosophy 77 (1980); reprinted in his Music, Art and Metaphysics , 63–88. This paper has, perhaps, been the most influential account of the nature of musical works, post-Wollheim. Presuming the type-token theory to be correct, Levinson elaborates it by claiming musical works to be, not sound structures (i.e. structured patterns of sound-types), but a species of types he calls indicated structures . According to Levinson, a work of music is not to be identified with its sound structure, S ; it is, in fact, a compound of S and a performance-means structure, PM , as indicated (typically, via a score) by its composer on a certain occasion : something that we can represent as S/PM -as-indicated-by- X -at- t . Such indicated structures, Levinson argues, fit the bill for being what works of music are, because they come into being with their indication (i.e. their composition), are individuated in terms of the musico-historical context in which they were composed, and have their specified performance-means (i.e. their instrumentation) essentially. Wolterstorff, Nicholas. Works and Worlds of Art . Oxford: Clarendon Press, 1980. Part I of this book sees Wolterstorff defend a Platonistic version of the type-token theory (although Wolterstorff calls them 'kinds' rather than 'types'). According to Wolterstorff, considerations about the existence conditions of types commit us to the thesis that works of music, qua types, are entities that cannot come into or go out of existence. Kivy, Peter. 'Platonism in Music: A Kind of Defence.' Grazer Philosophische Studien 19 (1983): 109–29. In this article, Kivy ingeniously (and wittily) defends a variety of Platonism about works of music against the animadversions of Levinson. Currie, Gregory. An Ontology of Art . New York: St, Martin's Press, 1989. Here Currie introduces and defends the thesis that works of music (and, indeed, all artworks) are compositional action-types. The book also contains some well-aimed criticisms of Levinson's account. Dodd, Julian. Works of Music: An Essay in Ontology . Oxford: Oxford University Press, 2007. In this book, Dodd defends the type-token theory, but argues that no version of it can escape the Platonisic consequence that musical works exist at all times (and hence, are discovered, rather than created, by their composers). Dodd also defends another controversial thesis, this time concerning musical works' individuation. According to Dodd, and pace Levinson and others, sonicism is correct: works that sound exactly alike are identical. Rohrbaugh, Guy. 'Artworks as Historical Individuals.' European Journal of Philosophy 11 (2003): 177–205. In this essay, Rohrbaugh makes some pointed criticisms of the type-token theory of repeatable artworks in the course of arguing that such works should be viewed, not as types, but as historical individuals (see above). Rohrbaugh suggests that treating musical works as historical individuals best captures our intuitions about such works' temporal and modal characteristics, and, in the course of elaborating his position, he makes some meta-ontological claims that see him endorsing a non-revisionary, descriptivist approach to the ontology of art. As Rohrbaugh sees it, ontologies of art are 'beholden to our artistic practices' (179), and 'aesthetics should not be beholden to the metaphysics on offer, but rather should drive new work in metaphysics' (197). Ridley, Aaron. 'Against Musical Ontology,' Journal of Philosophy 100 (2003): 203–220. This paper sees Ridley outlining a sceptical attitude towards the project of formulating ontological proposals. In his view, a 'serious philosophical engagement with music is orthogonal to, and may well in fact be impeded by, the pursuit of ontological issues' (203). Thomasson, Amie. 'The Ontology of Art and Knowledge in Aesthetics.' JAAC 63 (2005:221–9). Thomasson defends descriptivism in the ontology of art by arguing that such a position is a consequence of the only defensible solution to a problem in the theory of reference: the so-called 'qua' problem concerning how the reference of a term can be fixed. Davies, David. Art as Performance . Oxford: Blackwell, 2004. Davies' position is characterised by two theses: one methodological, the other ontological. The methodological claim is that the ontology of art faces a pragmatic constraint : roughly speaking, the ontology of art is answerable to the epistemology of art. The ontological claim is that the rigorous enforcement of the pragmatic constraint commits us to the thesis that all artworks are compositional action-tokens.

This article examines one way in which a fiction can carry ontological commitments. The ontological commitments that the article examines arise in cases where there are norms governing discourse about items in a fiction that cannot be accounted for by reference to the contents of the sentences that constitute a canonical telling of that fiction. In such cases, a fiction may depend for its contents on the real-world properties of real-world items, and the fiction may, in that (...) sense, be ontologically committed. Having outlined a way of gauging the ontological commitments of a fiction, the article concludes by illustrating the way in which these considerations can be put to work in assessing the prospects of using fictionalism as a tactic for understanding the metaphysics of modality without incurring a commitment to the real existence of merely possible worlds.

Emotion education is enjoying new-found popularity. This paper explores the ‘cosy consensus’ that seems to have developed in education circles, according to which approaches to emotion education are immune from metaethical considerations such as contrasting rationalist and sentimentalist views about the moral ontology of emotions. I spell out five common assumptions of recent approaches to emotion education and explore their potential compatibility with four paradigmatic moral ontologies. I argue that three of these ontologies fail to harmonise with the common (...) assumptions. Either those three must therefore be rejected or, if we want to retain one or more of them, we need to revise our assumptions about the practice of emotion education in ways that are both radical and, I argue, ultimately unacceptable.

The most important argument against the B-theory of time is the paraphrase argument. The major defense against that argument is the “new” tenseless theory of time, which is built on what I will call the “indexical reply” to the paraphrase argument. The move from the “old” tenseless theory of time to the new is most centrally a change of viewpoint about the nature and determiners of ontological commitment. Ironically, though, the new tenseless theorists have generally not paid (...) enough sustained, direct attention to that notion. I will defend a general criterion of ontological commitment and apply it to generate a version of the new tenseless theory of time. I will argue that many of the extant versions of the new tenseless theory of time (specifically, all those which seek to identify tenseless truth-conditions of tensed sentences as a way out of apparent ontological commitment to tensed features of reality) are unsatisfactory because their general criterion of ontological commitment is inadequate. Those versions of the new tenseless theory which are adequate (specifically, those which identify tenseless truthmakers for tensed sentences) actually entail the criterion of ontological commitment that I defend, despite appearances to the contrary.

The article explicates psychological and ontological aspects of Inference to the Best Explanation . IBE is a psychological theory, because cognitive science studies support IBE as descriptively true and psychologically adequate theory, i.e., people perceive best explanations as true and follow the rule of IBE in their reasoning. Moreover, different features of IBE imply that conclusions of IBE can be true only in a world with a very particular ontological constitution. Realism about the external world, the uniformity (...) of nature, the truth of background knowledge and the truth-conduciveness of explanatory virtues are necessary and sufficient for IBE to be truth-conducive. Therefore, IBE is an epistemic theory only because at the same time it is committed to a particular ontology. Keywords: inference to the best explanation, abduction, psychology, ontology, explanatory virtues. (shrink)

William of Ockham (d. 1347) is well known for his commitment to parsimony and for his so-called ‘razor’ principle. But little is known about attempts among his own contemporaries to deflect his use of the razor. In this paper, I explore one such attempt. In particular, I consider a clever challenge that Ockham’s younger contemporary, Walter Chatton (d. 1343) deploys against the razor. The challenge involves a kind of dilemma for Ockham. Depending on how Ockham responds to this (...) dilemma, his razor will, Chatton argues, either prove unacceptably dull when it comes to determining ontological commitment or prove unacceptably sharp when it comes to determining commitments entailed by certain theological doctrines. While Chatton’s objection is subtle and interesting in its own right, the broader significance of the debate between these thinkers lies in the light it sheds on medieval approaches to issues surrounding metaphysical methodology.

abstract This article attempts to illustrate the continuing need to pay attention to ontological issues connected with the conduct of empirical research and subsequent policy making. Failure to do so leads to the conflation of social constructions with ideas about the thesis of an independent reality. Such category mistakes often lead to dilemmas in which culturally sensitive constructs may, on the one hand, be worthy of study because they do tell us how socially constructed categories do predict social (...) phenomena; but, on the other hand, such constructs may illustrate an unwillingness on the part of the research community to recognize the objective nature of such constructs. Some recommendations are suggested for addressing the social policy consequences of these dilemmas. (shrink)

Gideon Rosen’s [1990 Modal fictionalism. Mind, 99, 327–354] Modal Fictionalist aims to secure the benefits of realism about possible-worlds, whilst avoiding commitment to the existence of any world other than our own. Rosen [1993 A problem for fictionalism about possible worlds. Analysis, 53, 71–81] and Stuart Brock [1993 Modal fictionalism: A response to Rosen. Mind, 102, 147–150] both argue that fictionalism is self-defeating since the fictionalist is tacitly committed to the existence of a plurality of worlds. In (...) this paper, I develop a new strategy for the fictionalist to pursue in response to the Brock–Rosen objection. I begin by arguing that modal fictionalism is best understood as a paraphrase strategy that concerns the propositions that are expressed, in a given context, by modal sentences. I go on to argue that what is interesting about paraphrastic fictionalism is that it allows the fictionalist to accept that the sentence ‘there is a plurality of worlds’ is true without thereby committing her to the existence of a plurality of worlds. I then argue that the paraphrastic fictionalist can appeal to a form of semantic contextualism in order to communicate her status as an anti-realist. Finally, I generalise my conception of fictionalism and argue that Daniel Nolan and John O’Leary-Hawthorne [1996 Reflexive fictionalisms. Analysis, 56, 26–32] are wrong to suggest that the Brock-Rosen objection reveals a structural flaw with all species of fictionalism. (shrink)

According to ontological nihilism nothing exists. A recent argument purports to show that this view is indefensible, since its most plausible formulations are tacitly committed to quantificational claims that are inconsistent with the nihilist's view that there aren't any existents. I show that this objection begs the question against the nihilist. The objector's argument relies on an equivalence principle implying that claims which nihilists regard as non-quantificational should nonetheless be interpreted as equivalent to quantified claims, given that both kinds (...) of assertion are assertible in the same contexts. This style of reasoning is supported by considerations of charity, which suggest that similarities in inter-personal patterns of language use provide evidence of similarity in the semantic content of speakers' utterances. However, related considerations also suggest that intra-personal patterns of language use constitute significant semantic evidence of the same kind. When we appreciate this and further recognize that nihilists are disposed to assert the negation of any positive, quantified claim, we see that it is too much to expect principles of semantic interpretation based on considerations of charity to decisively refute nihilism. This result has interesting metametaphysical implications concerning the role and scope of analogous arguments based on principles of interpretive charity. (shrink)

I provide an opinionated overview of the literature on the relationship of contextualism to knowledge norms for action, assertion, and belief. I point out that contextualists about ‘knows’ are precluded from accepting the simplest versions of knowledge norms; they must, if they are to accept knowledge norms at all, accept “relativized” versions of them. I survey arguments from knowledge norms both for and against contextualism, tentatively concluding that commitment to knowledge norms does not conclusively win the (...) day either for contextualism or for its rivals. But I also suggest that an antecedent commitment to contextualism about normative terms may provide grounds for suspicion about knowledge norms, and a debunking explanation of some of the data offered in favor of such norms.

In this chapter, I examine Lewis's ideas about ontological innocence, ontological commitment and double-counting, in his discussion of composition as identity in Parts of Classes. I attempt to understand these primarily as epistemic or methodological claims: how far can we get down this route without adopting radical metaphysical theses about composition as identity?

The modus operandi of this book is contextual—throughout he demonstrates how ideas emerge from or are inspired by particular environments. And the need to put philosophical ideas in their larger historical and cultural context so as to fully understand them is, as will be illustrated below, a facet of his philosophical method. Another of its facets is fallibilism, a deep commitment to subjecting all theories and concepts (in any field) to incessant scrutiny, testing, correction, and clarification. This suggests that (...) a totality of knowledge of the world or the absolute truth about things is a pair of ideals impossible of realization and approachable at best asymptotically. If his method is contextualist and fallilbilist, then his metaphysics is pluralistic. In his view reality is not reducible to just one single substance or principle but instead is constituted irreducibly of many different kinds of thing or principles. He is thus implacably opposed to any form of ontological monism—what James designates a “block-universe”—and Hegelian absolutism. Callaway conceives of the world as a Jamesian multiverse. Contextualism, fallibilism, and pluralism, then, are the themes brought to the fore in his book and which emerge from his travels at home and abroad. (shrink)

This very short introduction will first outline how ontological investigations and questions of practice go together. The second section will bring in the next pole of this entire book, history of mathematics. How do ontology, practice, and history go together? Is this a forced marriage or one born in true love? That is, do these three belong together in some very basic way? One chapter in the section argues that the philosophy of mathematical practice intersects with the history of (...) mathematics essentially. If the first section of this introduction is persuasive that will also show that the history of mathematics intersects with ontological questions as well, specifically, that historical questions are very much about the ontological commitments of past mathematicians. The last section will take up what might seem a very different theme, namely, how these things matter to mathematics education. This section is connected closely to the second section since mathematics education has taken an interest in the role of history of mathematics in mathematics education, and much insight can be gained by seeing the issues in relation to the ontology-practice-history triad. The question of education is also important since teachers must consider what it is exactly that they are teaching, or, to adapt the title of Reuben Hersh’s well-known book, “What is mathematics really about?” And the “aboutness” of mathematics is really the ontological question.

The inherent normativity of HTA can be conceptualized as a result of normative commitments, a concept that we further specify to encompass moral, epistemological and ontological commitments at play in the practice of HTA. Based on examples from literature, and an analysis of the example of assessing Non-Invasive Prenatal Testing (NIPT), we will show that inevitable normative decisions in conducting an assessment commits the HTA practitioner to moral (regarding what makes a health technology desirable), ontological (regarding which effects (...) of health technology are conceivable), and epistemological (regarding how to obtain reliable information about health technology) norms. This highlights and supports the need for integrating normative analysis and stakeholder participation, providing guidance to HTA practitioners when making normative choices. This will foster a shared understanding between those who conduct, use, or are impacted by assessments regarding what are conceivable and desirable outcomes of using health technology, and how to collect reliable information to assess whether these outcomes are (going to be) realized. It also provides more insight into the implications of different normative choices. (shrink)

Smart Contracts enable the automated execution of exchanges on the blockchain. From an ontological perspective, smart contracts create and automate the fulfillment of social commitments between actors. Whereas traditional deontic logic is used to make a legal determination in contractual multi-actor interactions, this paper focuses on the consequences of these actions resulting from that determination, thereby shifting the focus from monitoring to execution. The interactions between actors and the consequences in terms of commitments have not yet been formalized for (...) smart contracts. The perspective of smart contracts is interesting, since they are considered to be autonomous agents, able to generate automated actions. We use the Event Calculus as a formal logic to represent and reason about the effects of these automated actions and the resulting commitments. Since the Event Calculus deals with local events and the consideration of time, this approach enables the uniform representation of commitments, including their operations and reasoning rules.

In this paper, we examine the meta-ontology of AI systems with human-level intelligence, with us denoting such AI systems as AI E. Meta-ontology in philosophy is a discourse centered on ontology, ontological commitment, and the truth condition of ontological theories. We therefore discuss how meta-ontology is conceptualized for AI E systems. We posit that the meta-ontology of AI E systems is not concerned with computational representations of reality in the form of structures, data constructs, or computational concepts, (...) while the ontological commitment of AI E systems is directed toward what exists in the outside world. Furthermore, the truth condition of the ontology (which is meta-ontological assumption) of AI E systems does not require consistency with closed conceptual schema or ontological theories but rather with reality, or in other words, “what is the world” (Smith, 2019, p.57). In addition, the truth condition of AI E systems is verified through operational success rather than by coherence with theories. This work builds on ontological postulates about AI systems that were formulated by Brian Cantwell Smith (2019). (shrink)

Political theory is contextualist when factual claims about context are part of the justification of normative political judgments. There are different kinds of contextualism depending on whether context is relevant for the formulation and justification of political principles, whether principles themselves are contextually specific, or whether context is only relevant for the application of principles. An important challenge to contextualism is the problem of critical distance: how can theories ensure a critical perspective if facts about the (...) context to be evaluated are also part of the justification for the normative judgments? Tariq Modood and Simon Thompson have defended what they call iterative contextualism, which combines elements of all three kinds of contextualism in an attempt to avoid the problem of critical distance. The present paper discusses Modood and Thompson’s iterative contextualism and whether it manages to avoid the problem of critical distance. (shrink)

Existing proposals concerning the ontology of quantum mechanics either involve speculation that goes beyond the scientific evidence or abandon realism about large parts of QM. This paper proposes a way out of this dilemma, by showing that QM as it is formulated in standard textbooks allows for a much more substantive ontological commitment than is usually acknowledged. For this purpose, I defend a non-fundamentalist approach to ontology, which is then applied to various aspects of QM. In particular, (...) I will defend realism about spin, which has been viewed as a particularly hard case for the ontology of QM. (shrink)

Easy Ontology (EO), defended in several recent works by Amie Thomasson, and based on Carnap’s famous deflationism about metaphysics, is the view that many ontological questions, like ‘Are there numbers?’, are at bottom easy, at least when taken in their “internal” sense. Both Carnap and Thomasson take for granted that serious metaphysicians therefore cannot plausibly be interpreted as asking internal questions. Thus, they think they are committed to finding some alternative, special interpretation of metaphysicians’ utterances. I argue that (...) none of the alternative interpretations proposed in the literature are viable. More importantly, I argue that Carnap and Thomasson are wrong about this commitment. EO should instead be coupled with the view that metaphysicians ask internal questions, yet have the false belief that they can be answered only through metaphysical speculation. This is a significant modification of EO, in which the notion of an “external question” plays no role, and which results in a simpler and more plausible theory. (shrink)

Including the perspectives of scientists about the nature and process of science is important for an authentic and nuanced portrayal of science in science education. The small number of studies that have explored scientists’ worldviews about science has thus far generated contradictory findings, with recent studies claiming that scientists simultaneously hold contradictory sophisticated and naïve views. This article reports on an exploratory study that uses the framework of Bhaskar’s critical realism to elicit and separately analyse academic scientists’ (...) class='Hi'>ontological and epistemological views about science in semi-structured interviews. When the views of scientists are analysed through the lens of critical realism, it is clear that it is possible to hold a realist ontological commitment about what knowledge is of, simultaneously with a fallibilist epistemological commitment about knowledge itself. The apparent incongruence of scientists’ so-called naïve and sophisticated views about science is resolved when analysed using a critical realist framework. Critical realism offers a simple and coherent framework for science educators that avoids many of the problems of positivism and social constructivism by finding a middle ground between them. The three pillars of critical realism: ontological realism, epistemological fallibilism and judgmental rationality help to make sense of how socially constructed scientific knowledge can be anchored in an independent reality.

Ontology, since Aristotle, has been conceived as a sort of highly general physics, a science of the types of entities in reality, of the objects, properties, categories and relations which make up the world. At the same time ontology has been for some two thousand years a speculative enterprise. It has rested methodologically on introspection and on the construction and analysis of elaborate world-models and of abstract formal-ontological theories. In the work of Quine and others this ontological theorizing (...) in abstract fashion about the world was supplemented by the study, based on the use of logical methods, of the ontological commitments or presuppositions embodied in scientific theories. In recent years both types of ontological study have found application in the world of information systems, for example in the construction of frameworks for knowledge representation and in database design and translation. As ontology is in this way drawn closer to the domain of real-world applications, the question arises as to whether it is possible to use empirical methods in studying ontological theories. More specifically: can we use empirical methods to test the ontological theories embodied in human cognition? We set forth the outlines of a framework for the formulation and testing of such theories as they relate to the specific domain of geographic objects and categories. (shrink)

In ethical discourse, it is common practice to distinguish between normative commitments and descriptive commitments. Normative commitments reflect what a person ought to be committed to, whereas descriptive commitments reflect what a person actually is committed to. While the normative/descriptive distinction is widely accepted as a way of talking about ethical commitments, philosophers have missed this distinction in discussing ontological commitments. In this paper, I distinguish between descriptive ontological commitments and normative ontological commitments and discuss several (...) significant benefits of recognizing this distinction. I argue that just as the normative/descriptive distinction is important for fruitful ethical discourse, so too is it important for fruitful discourse concerning our ontological commitments. And, it constitutes a significant step towards resolving some prominent debates concerning our ontological commitments. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Experiential Avoidance and Superstition: Considering Concepts in ContextRoger Vilardaga (bio) and Steven C. Hayes (bio)Keywordsacceptance, contextualism, influence, therapyThe target article (García-Montes et al. 2008) explores the application of the concept of superstition, examined from a Sartrian perspective, to psychopathology such as obsessive–compulsive disorder and psychosis. They compare their analysis to two different technical terms taken from current research programs in psychology, which are the notions of Thought–Action Fusion (...) and Experiential Avoidance (EA). We have been asked to respond because our work in Acceptance and Commitment Therapy (ACT; Hayes, Strosahl, and Wilson 1999) and Relational Frame Theory (RFT; Hayes, Barnes-Holmes, and Roche 2001) are part of the foundational work in EA, and thus in this short commentary we comment on the article from the point of view of our research program.The article notes several areas of overlap between the ACT/RFT work on EA and their Sartrian perspective on superstition, such as the holistic and contextualistic nature of the analysis, but also several differences which the authors feel advantage their own view.It is difficult to compare the two lines of work without appreciating their context and purpose. Sartre was not a scientific psychologist; ACT/RFT are part of a specific effort at scientific system building, which we term here “contextual behavioral science” (AKA, post-Skinnerian behavior analysis).Contextual behavioral science is a social enterprise that has as its purpose the development of increasingly organized statements of relations among events that allow actions embedded in their historical and situational context to be predicted and influenced with precision, scope, and depth. “Precision” means that a limited set of analytic constructs apply to any one event; “scope” means that a limited set of constructs are needed to analyze a broad range of events; and “depth” means that constructs should cohere across different levels of analysis.Although a real world (or at least the one world) is assumed, the partitioning of the world is thought to be the result of our continuous interactions in and with it. These partitions are not ontological constructions from the perspective of contextual behavioral science because they, too, are actions that are purposive and embedded in their historical and situational contexts. The [End Page 269] deliberate attempt to analyze the world scientifically does not contradict the holistic standpoint of contextualism. When analytic goals are accomplished, constructs are “true,” but multiple truths are possible given multiple goals and historical and situational contexts. Conversely, all forms of contextualism become dogmatic and self-contradictory if their goals are not stated. It is common for contextualists of all varieties to state and defend the ultimate apprehension of reality as a whole, for example, without realizing that any statement about the world including such a defense is a form of breaking down this whole into parts. As we will try to show, the target article seems to fall into this usual contextualistic trap by arguing for what is better, without stating clearly “better for what, assessed how” and without viewing concepts with relevance to their purpose.Prediction and influence with precision, scope, and depth is a purpose, stated naked and in the wind. It is not defended, justified, or given ontological status. To generate powerful ways of speaking as measured against that purpose, contextual behavioral science has embraced a wide variety of methodologies, including laboratory research designed to refine behavioral principles with high levels of precision and scope, and applied research such as randomized controlled trials, analog research, and measure development that test the scope of the principles and theories that result (e.g., Hayes et al. 2006). Whether concepts like EA are helpful is a matter to be considered relevant to the goals of the analysis.As example of the kind of problems the authors create for themselves, consider the following quote from the target article:Although the post-Skinnerians who proposed the EA concept call themselves “contextualists,” they pay no more than lip service to the role of the “social/verbal community” and the cultural context. Their research focuses almost exclusively on laboratory experiments, and does not consider the important role of particular social practices and contexts, such as modernity.(García... (shrink)

A defense of an ontology of propositions and of some logical resources for representing them. It begins with an austere formulation of a theory of propositions in a first-order extensional logic, but then uses the commitments of this theory to justify an enrichment to modal logic - the logic of necessity and possibility - as an appropriate framework for regimented languages that are constructed to represent any of our scientific and philosophical commitments. Both the proof-theory and the model theory of (...) a first-order quantified modal logic are developed in detail, and it is argued that these formal resources help to sharpen questions about ontology and predication. The clarification of predication helps to provide a motivation for extending our ontological commitment to properties and relations that are expressed by predicates, and for extending the logic to a higher-order modal logic that provides a conception of metaphysical modality that allows for the contingent existence, not only of persons and physical objects, but also of properties, relations and propositions. Even though both the specific ontological commitments defended (to propositions, properties and relations) and the logical resources that are used to defend them (modal and higher-order logic) were famously rejected by W. V. Quine, the book adopts a self-consciously neo-Quinean methodology, and argues that the theory that is developed helps to motivate and clarify Quine's naturalistic metaphysical picture. (shrink)

Brian Epstein has recently argued that a thoroughly microfoundationalist approach towards economics is unconvincing for metaphysical reasons. Generally, Epstein argues that for an improvement in the methodology of social science we must adopt social ontology as the foundation of social sciences; that is, the standing microfoundationalist debate could be solved by fixing economics’ ontology. However, as I show in this paper, fixing the social ontology prior to the process of model construction is optional instead of necessary and that metaphysical-ontological (...) commitments are often the outcome of model construction, not its starting point. By focusing on the practice of modeling in economics the paper provides a useful inroad into the debate about the role of metaphysics in the natural and social sciences more generally. (shrink)

Contemporary political thought is deeply divided about the role of ontology in political thinking. Famously, political liberal John Rawls has argued that ontological claims are best to be avoided in political thought. In recent years, however, a number of theorists have claimed that ontology is essential to political philosophy. According to the contributors to this ‘ontological turn’, ontological investigations may foster the politicisation of hegemonic political theories and can highlight new possibilities for political life. This essay (...) aims to contribute to the debate about ontology in political philosophy by arguing that a compelling case for ontology can also be made in light of Rawls’ political liberalism itself, in particular, by taking seriously Rawls’ commitment to the politicisation of justice and the task of orientation of political philosophy. To make this case, the paper brings Rawls' perspective in conversation with the critical methodology and the ontology of agonism and reflections on parr... (shrink)

Early analytic philosophers like Carnap, Wittgenstein and Ryle regarded ontology as a branch of metaphysics that is either trivial or meaningless. But at present it is generally assumed that philosophy can make substantial discoveries about what kinds of things exist and about the essence of these kinds. My paper challenges this ontological turn. The currently predominant conceptions of the subject, at any rate, do not license the idea that ontology can provide distinctively philosophical insights into the constituents (...) of reality. I distinguish four main sources of analytic ontology—Strawson's descriptive metaphysics, Kripke's realist semantics, the Austro-Australian truth-maker principle, Quine's naturalistic conception of ontology—and indicate briefly why the first three do not rehabilitate ontology. In the remainder, I concentrate on the most influential and promising position. Quinean ontology seeks to bring out and reduce the ontological commitments of our best scientific theories through logical paraphrase. Against this programme, I argue that Quine's conception of ontological commitment is inadequate, and that his logical paraphrase cannot contribute to the exploration of reality, but at most to the clarification of our conceptual framework.

Digital physics claims that the entire universe is, at the very bottom, made out of bits; as a result, all physical processes are intrinsically computational. For that reason, many digital physicists go further and affirm that the universe is indeed a giant computer. The aim of this article is to make explicit the ontological assumptions underlying such a view. Our main concern is to clarify what kind of properties the universe must instantiate in order to perform computations. We analyse (...) the logical form of the two models of computation traditionally adopted in digital physics, namely, cellular automata and Turing machines. These models are computationally equivalent, but we show that they support different ontological commitments about the fundamental properties of the universe. In fact, cellular automata are compatible with a rather traditional form of physicalism, whereas Turing machines support a dualistic ontology, which could be understood as a realism about the laws of nature or, alternatively, as a kind of panpsychism.
