Recently, some philosophers have attempted to escape familiar challenges to orthodox nonnaturalist normative realism by abandoning the robust metaphysical commitments of the orthodox view. One such view is the ‘Non-Metaphysical Non-Naturalism’ or ‘Non-Realist Cognitivism’ proposed by Derek Parfit and a few others. The trouble is that, as it stands, Non-Realist Cognitivism seems unable to provide a substantive non-trivial account of the meaning and truth conditions of moral claims. The paper considers various strategies one might use to address the (...) challenge. There is a rich field of views that are cognitivist and non-realist. But the paper is skeptical of the prospects of Non-Realist Cognitivism. (shrink)

The structure of natural languages is usually studied from three major different but interconnected points of view: syntax, semantics, and pragmatics. If we consider that the main purpose of natural languages is communication, we should consider another dimension for languages, which deals with the influence of internal states of communicating individuals on meanings. Such a dimension we refer to as internalism. Within this context, internalism cannot be confused with psycholinguistics, in the same way pragmatics cannot be confused with sociolinguistics. In (...) particular, we argue, language is tied to its systematic use. This view leads us to a non-realist perspective on linguistics. We analyze the role of natural languages into dialogues, by comparing our proposal to the dialogical approach to logic, which considers a dialogue as a game. Within our approach, there is no way to guarantee that two parties involved in a dialogue are playing the same game, due to unavoidable differences in their respective internal states. Another contribution of this paper is to argue that semantics plays a more fundamental role than syntax in the cognitive acquisition of languages. (shrink)

Non-Relational Realism is a popular solution to the Bradleyan regress of facts or truths. It denies that there is a relational universal of exemplification; for an object a to exemplify a universal F-ness, on this view, is not for a relation to subsist between a and F-ness. An influential objection to Non-Relational Realism is that it is unacceptably obscure. The author argues that Non-Relational Realism can be understood as a selective application of satisfaction semantics to predicates like ‘exemplify’, and that (...) so understood, it is not obscure. This kind of selective use of satisfaction semantics may be feasible in other contexts as a means of making theories more parsimonious. (shrink)

Anti-realistic conceptions of truth and falsity are usually epistemic or inferentialist. Truth is regarded as knowability, or provability, or warranted assertability, and the falsity of a statement or formula is identified with the truth of its negation. In this paper, a non-inferentialist but nevertheless anti-realistic conception of logical truth and falsity is developed. According to this conception, a formula (or a declarative sentence) A is logically true if and only if no matter what is told about what is told about (...) the truth or falsity of atomic sentences, A always receives the top-element of a certain partial order on non-ontic semantic values as its value. The ordering in question is a told-true order. Analogously, a formula A is logically false just in case no matter what is told about what is told about the truth or falsity of atomic sentences, A always receives the top-element of a certain told-false order as its value. Here, truth and falsity are pari passu , and it is the treatment of truth and falsity as independent of each other that leads to an informational interpretation of these notions in terms of a certain kind of higher-level information.

This paper reviews the situation with respect to the referential approach to the problem of semantic incommensurability. It argues that the thesis of semantic incommensurability does not pose a significant threat to scientific realism. However, there exists a "non-realist" defence of incommensurability, according to which the referential approach begs the question against advocates of the incommensurability thesis. This defence is criticized, and the basis for a realist response to incommensurability is presented.

Three influential forms of realism are distinguished and interrelated: realism about the external world, construed as a metaphysical doctrine; scientific realism about non-observable entities postulated in science; and semantic realism as defined by Dummett. Metaphysical realism about everyday physical objects is contrasted with idealism and phenomenalism, and several potent arguments against these latter views are reviewed. -/- Three forms of scientific realism are then distinguished: (i) scientific theories and their existence postulates should be taken literally; (ii) the existence of unobservable (...) entities posited by our most successful scientific theories is justified scientifically; and (iii) our best current scientific theories are at least approximately true. It is argued that only some form of scientific realism can make proper sense of certain episodes in the history of science. -/- Finally, Dummett’s influential formulation of semantic issues about realism considered. Dummett argued that in some cases, the fundamental issue is not about the existence of entities, but rather about whether statements of some specified class (such as mathematics) have an objective truth value, independently of our means of knowing it. Dummett famously argued against such semantic realism and in favor of anti-realism. The relation of semantic realism to the metaphysical construal of realism and Dummett’s main argument against semantic realism is examined. (shrink)

This article argues, first, that the fundamental structure of the skeptical argument in Kripke's book on Wittgenstein has been seriously misunderstood by recent commentators. Although it focuses particularly on recent commentary by John McDowell, it emphasizes that the basic misunderstandings are widely shared by other commentators. In particular, it argues that, properly construed, Kripke offers a fully coherent reading of PI #201 and related passages. This is commonly denied, and given as a reason for rejecting Kripke's reading of Wittgenstein's text. (...) Second, it is pretty universally accepted that Kripke's Wittgenstein is a `non-factualist' about ascriptions of meaning. The article argues that, when Kripke's discussion is rightly understood and the content of `non-factualism' is clarified, there is an important sense in which the skeptical solution is not committed to non-factualism.

Putnam’s internal realism implies a form of conceptual relativity with respect to ontology. There can be different descriptions of the world which are based on distinct ontologies. It has been argued that this relativity forecloses any possibility of unifying our knowledge and can even lead to inconsistency. If this is true, internal realism should be abandoned because it is compatible with non-rational positions. We will argue that these objections can be dismissed if truth as idealized warranted assertibility is understood as (...) stability of a belief state under new evidence. This view of truth is still compatible with the existence of distinct belief states expressing different views on the world. This understanding of the notion of truth is a consequence of interpreting both our cognitive activities and the notion of meaning dynamically. The meaning of a sentence is no longer given in terms of (static) truth conditions but as a relation between belief sets, that is, as a kind of information change potential. (shrink)

The purpose of this article is to articulate the possibility of semantic non-doxastic agnostic religious faith. Robin Le Poidevin, who introduced the idea of semantic religious agnosticism, defines it as being agnostic about which parts of religion to treat in realist terms and which parts to treat in fictionalist terms. I take Le Poidevin’s view and argue that it is consistent with a non-doxastic attitude toward the object of faith such as acceptance. I then explore the similarities and differences (...) between my account and a prominent version of non-doxastic faith found in the work of Daniel Howard-Snyder. One advantage of my theory of faith is that it allows a person to be even more sceptical about religion than other versions of agnosticism while simultaneously avoiding some of the problems frequently associated with religious fictionalism.

Normative realists might be assumed to have few worries about semantics. After all, a realist might initially hope to simply adopt the best semantic theory about ordinary descriptive language. However, beginning with the non-cognitivist appropriation of the open question argument, a number of philosophers have posed serious objections to the realist’s ability to offer a plausible semantic theory. This paper introduces the two most influential semantic challenges to normative realism: the open question argument, and the Moral Twin Earth (...) argument. It explains the major replies to these challenges offered by realists, and locates these challenges within the broader debate over what sort of semantic theories might be plausible candidates for a normative realist to adopt.

In his 1982 book Wittgenstein on Rules and Private Language, Saul Kripke develops a famous argument that purports to show that there are no facts about what we mean by the expressions of our language: ascriptions of meaning, such as “Jones means addition by ‘+’” or Smith means green by ‘green’”, are according to Kripke’s Wittgenstein neither true nor false. Kripke’s Wittgenstein thus argues for a form of non-factualism about ascriptions of meaning: ascriptions of meaning do not purport to state (...) facts. Define semantic realism to be the view that ascriptions of meaning are apt to be assessed in terms of truth and falsity, and are, at least in some instances, true. Semantic realism, thus defined, is a form of cognitivism about semantic judgement, according to which judgements ascribing meaning express beliefs, states apt for assessment in terms of truth and falsity. Kripke’s Wittgenstein thus argues against semantic realism, and in favour of a form of semantic non-cognitivism.1 En route to semantic non-cognitivism, Kripke’s Wittgenstein argues against dispositionalist theories of meaning, which hold something roughly along the lines of the following: Jones means magpie by “magpie” if and only if Jones is disposed to apply “magpie” to magpies in ideal conditions (where the ideal conditions can be specified in terms that don’t presuppose the notion of meaning, and are such that in those conditions Jones applies “magpie” to a thing if and only if that thing is a magpie).

Empirical investigations use empirical methods, data and evidence. This banal observation appears to favour empiricism, especially in philosophy of science, though no rationalist ever denied their importance. Natural sciences often provide what appear to be, and are taken by scientists as, realist, causal explanations of natural phenomena. Empiricism has never been congenial to scientific realism. Bas van Fraassen’s ‘Constructive Empiricism’ purports that realist interpretations of any scientific theory in principle always transcend whatever can be justified by that theory’s (...) empirical adequacy, and that ‘explanations’ are merely pragmatic, insofar as they are context-specific to the presuppositions of whomever poses the question an explanation is to answer. Here I argue that ‘Constructive Empiricism’ rests upon a series of flawed presumptions about natural science and about epistemology. To do so I draw upon two main resources. One resource is the constraints upon specifically cognitive reference to particulars, first identified by Kant (and later by Evans). The second is William Harper’s (2011) brilliant re-analysis and defence of Newton’s Principia, which shows that, and how, Newton justified his realism about gravitational force. One surprise is that Kant’s semantics of singular cognitive reference (examined in §3) directly and strongly supports Newton’s Rule 4 of scientific method (§4), which strongly supports his realism about gravitational force (summarised in §2). A further surprise is that Hegel first recognised that this semantics of singular cognitive reference directly and strongly supports Newton’s methodological Rule 4 of experimental philosophy in ways which support Newton’s realism about gravitational force, and about distance forces generally. The textual and exegetical issues these attributions require I examine elsewhere. Here I make these important findings available to philosophers and historians of science. (shrink)

This paper is an attempt to convince anti-realists that their correct intuitions against the metaphysical inflationism derived from some versions of mathematical realism do not force them to embrace non-standard, epistemic approaches to truth and existence. It is also an attempt to convince mathematical realists that they do not need to implement their perfectly sound and judicious intuitions with the anti-intuitive developments that render full-blown mathematical realism into a view which even Gödel considered objectionable. I will argue for the following (...) two theses: that realism, in its standard characterization, is our default position, a position in agreement with our pre-theoretical intuitions and with the results of our best semantic theories, and that most of the metaphysical qualms usually related to it depends on a poor understanding of truth and existence as higher-order concepts.

This thesis argues that we should consider extended modal realism as a new player in the debate about non-existence. The primary aim is to show that extended modal realism is a viable theory when it comes to solving problems of non-existence. At times I will argue that extended modal realism has advantages over Lewisian modal realism when it comes to examining the problems of non-existence, not only in the case of problems relating to thought but also problems concerning truth as (...) well. However, I do not intend for the proposed advantages of extended modal realism to be presented as knockdown arguments against other strategies. -/- Not only do I argue that extended modal realism is viable when it comes to solving these problems, but I also make adjustments and additions to the theory that supports the conclusion of this thesis, and I argue that these are improvements to the modal realist theory. I include arguments for a new theory of existence that removes the need for the extended modal realist to rely on set-theoretic notations to understand existence, which I consider problematic. I argue for the revival of the Lewis-Rosen proposal for truth-making and a semantic instrumentalist theory of thought, both of which naturally accompany extended modal realism. Throughout this thesis, I will comment on the proposals and strategies of other authors, and some of these comments will be critical. At this very early stage, I want to clarify that this thesis's success does not rest on showing that all other competitor theories fail. I only include critical comments to situate extended modal realism within the landscape of viable positions that are available for one to occupy. (shrink)

In recent years, several philosophers have recommended to moral realists that they adopt a hybrid cognitivist–expressivist moral semantics. Adopting a hybrid semantics enables the realist to account for the action-guiding character of moral discourse, and to account for the possibility of moral (dis)agreement between speakers whose moral sentences express different cognitive contents. I argue that realists should resist the temptation to embrace a hybrid moral semantics. In granting that moral judgments are partly constituted by conative attitudes, the realist (...) concedes too much to her anti-realist opponents: she concedes that, at its most fundamental level, moral disagreement is disagreement in attitude, and the resolution of deep moral disagreement is best guided by non-epistemic norms of inquiry. Furthermore, on a hybrid semantics, moral thought and truth ascriptions turn out to be more responsive to the conative contents of moral judgments than to the supposed propositional contents. Finally, a hybrid semantics makes it difficult to preserve the realist’s claim that moral truths are in a certain sense independent of appraisers’ attitudes. (shrink)

Roger Vergauwen seeks to provide an answer to the question, "How does language connect to the world?" He begins with the recent developments in formal semantics and from them constructs his own 'theory of reference' with which he considers the nature of the correspondence of the world. The author locates his metalogics between the philosophy of language and epistemology while he covers a range of models from Plato to Wittgenstein. Vergauwen assumes no previous technical or logical study. Contents: Introduction: The (...)

Traditional theists are, with few exceptions, global semantic realists about the interpretation of external world statement. Realism of this kind is treated by many as a shibboleth of traditional Christianity, a sine qua non of theological orthodoxy. Yet, this love affair between theists and semantic realism is a poor match. I suggest that everyone (theist or no) has compelling evidence drawn from everyday linguistic practice to reject a realist interpretation of most external world statements. But theists have further reason (...) to forswear this view, because those who insist on global semantic realism open themselves to the charge of hubris of a theologically inappropriate kind. If the arguments in this paper are sound, then neither God nor any of us have reason to apply a realist interpretation to all or even most statements about the external world. (shrink)

The paper deals with certain issues with which Olivecrona was mainly concerned in his Philosophy of Law, notably (i) his views about the logical or syntactical form of imperatives as used in the law, and (ii) his views on the semantics of imperatives in the law and on the question whether and to what extent the notions of truth and falsity are applicable to those imperatives at all. In the light of an important critical notice of Olivecrona's work by Marc-Wogau (...) (1940 ), we examine some textual evidence for attributing to Olivecrona a so-called Atheoretical Thesis to the effect that imperatives in the law are neither true nor false or lack truth-value altogether. We close the paper by commenting on the celebrated distinction due to Hedenius (1941 ) and further elaborated by Wedberg (1951 ) between genuine ("rule-stating") normative sentences in the law and spurious ones (stating merely that a given rule is (or is not) in force in a given society at a given time). Two interesting difficulties bound up with that distinction will be dealt with. By means of various quotations we try to capture something of the flavour characterizing the legal philosophical discussion in Sweden in the mid-twentieth century during la belle époque of Scandinavian Legal Realism of which Olivecrona was a typical representative.

SummaryThis paper addresses the question of what scientific realism implies and what it does not when it is articulated so as to provide the best defense against plausible philosophical alternatives. A summary is presented of “abductive” arguments for scientific realism, and of the epistemological and semantic conceptions upon which they depend. Taking these arguments to be the best current defense of realism, it is inquired what, in the sense just mentioned, realism implies and what it does not. It is concluded (...) that realism implies the strong rejection of epistemological foundationalism, a non‐Humean conception of causation and of explanation, and a causal rather than conceptual account of the unity of natural definitions. It is denied that realism implies bivalence or the existence of one true theory, one preferred vocabulary or one distinctly privileged science. It is further denied that realism implies that there are no unrecognized conventional aspects to scientific theorizing and it is denied that realism implies that scientists routinely do good experimental metaphysics.

This paper begins with a revaluation of Carnap's critique of existence questions, and finds that with modification his argument is successful in giving a prima facie cause for doubt that the ontological question addressed by religious realists and non-realists has content. The second part of the paper argues that these doubts can be met with proper attention to the role of truth in the religious realism debate. The paper concludes by arguing for a close relationship between the semantic and the (...) ontological varieties of religious realism. (shrink)

In a methodological milieu characterized by efforts to bring the methods of philosophy closer to the methods of the sciences, one can find, with increasing regularity, meta-ethical arguments relying on scientific theory or data. The received view appears to be that, not only is it implausible to think that a scientific vindication of a non-mentalist moral semantics will be forthcoming but that evidence from a variety of sciences threatens to undermine non-mentalist views. My aim is to push back against this (...) apparent consensus. The well-established phenomenon whereby moral judgments influence our attributions of putatively purely descriptive properties has come to be known as the Knobe Effect. Joshua Knobe has attempted to explain this surprising phenomenon by arguing that our folk psychological judgments are partially constituted by moral judgments. Drawing on an argument originally offered by Moore, I argue that if some instantiation of Knobe’s explanatory strategy is accurate, we have good reason to believe that mentalist moral semantics are untenable.

This paper examines whether realists can explain co-reference without appealing to subjects’ ideal convergence in judgment. This question is particularly pressing in the normative domain, since deep disagreement about the applicability of normative predicates suggests that different speakers may not pick out the same property when they use normative terms. Normative realists, we believe, have not been sufficiently aware of the difficulties involved in providing a theory of reference-determination. Our aim in this paper is to clarify the nature of this (...) reference-fixing task and the challenges that arise for a non-convergentist normative realist. Our focal point will be Richard Boyd’s externalist account, which has been a model for non-convergentist theories of reference in metaethics. A close examination of Boyd’s account of reference and the ways it could be developed or supplemented, we’ll argue, suggests that explaining co-reference without convergence in the normative domain is a more challenging problem than many realists have supposed.

The depth-bounded approach seeks to provide realistic models of reasoners. Recognizing that most useful logics are idealizations in that they are either undecidable or likely to be intractable, the approach accounts for how they can be approximated in practice by resource-bounded agents. The approach has been applied to Classical Propositional Logic (CPL), yielding a hierarchy of tractable depth-bounded approximations to that logic, which in turn has been based on a KE/KI system. -/- This Thesis shows that the approach can be (...) naturally extended to useful nonclassical logics such as First-Degree Entailment (FDE), the Logic of Paradox (LP), Strong Kleene Logic (K3 ) and Intuitionistic Propositional Logic (IPL). To do this, we introduce a KE/KI-style system for each of those logics such that: is formulated via signed formulae, consist of linear operational rules and branching structural rule(s), can be used as a direct-proof and a refutation method, and is interesting independently of the approach in that it has an exponential speed-up on its tableau system counterpart. The latter given that we introduce a new class of examples which we prove to be hard for all tableau systems sharing the V/& rules with the classical one, but easy for their analogous KE-style systems. Then we focus on showing that each of our KE/KI-style systems naturally yields a hierarchy of tractable depth-bounded approximations to the respective logic, in terms of the maximum number of allowed nested applications of the branching rule(s). The rule(s) express(es) a generalized rule of bivalence, is (are) essentially cut rule(s) and govern(s) the manipulation of virtual information, which is information that an agent does not hold but she temporarily assumes as if she held it. Intuitively, the more virtual information needs to be invoked via the branching rule(s), the harder the inference is for the agent. So, the nested application the branching rule(s) provides a sensible measure of inferential depth. We also show that each hierarchy approximating FDE, LP, and K3 , admits of a 5-valued non-deterministic semantics; whereas, paving the way for a semantical characterization of the hierarchy approximating IPL, we provide a 3-valued non-deterministic semantics for the full logic that fixes the meaning of the connectives without appealing to “structural” conditions. -/- Moreover, we show a super-polynomial lower bound for the strongest possible version of clausal tableaux on the well-known class of “truly fat” expressions (which are easy for KE), settling a problem left open in the literature. Further, we investigate a hierarchy of tractable depth-bounded approximations to CPL based only on KE. Finally, we propose a refinement of the p-simulation relation which is adequate to establish positive results about the superiority of a system over another with respect to proof-search. (shrink)

Are there fictional characters? Realists suggest that there are such entities, but these are non-concrete, non-actual or non-existent. Antirealists avoid this assumption by suggesting that fictional discourse is not to be taken at face value. However, any of these camps faces some serious troubles. This paper proposes a hybrid account that combines features of realism with features of antirealism. In particular, the semantic distinction between de dicto and de re is employed, and the resulting view suggests de dicto (role) realism (...) and de re antirealism. (shrink)

I offer an understanding of what it is for a term to be rigid which makes no serious metaphysical commitments to or about identity across possible worlds. What makes a term rigid is not that it 'refers to the same object(property) with respect to all worlds' - rather (roughly) it is that the criteria of application for the term with respect to other worlds, when combined with the criteria of identity associated with the term, ensure that whatever meets the criteria (...) of identity also meets the criteria of application and vice versa - in the simplest case, the criteria of application just are the criteria of identity - but things can be more complex to allow for the necessary a posteriori. This makes rigidity a non-metaphysically loaded semantic matters, and allows us to see that the phenomenon of and involving rigidity - especially the necessary a posteriori - are of no metaphysical significance on their own.

According to the realist, the meaning of a declarative, non-indexical sentence is the condition under which it is true and the truth-condition of an undecidable sentence can obtain or fail to obtain independently of our capacity, even in principle, to recognize that it obtains or that fails to do so.1 In a series of papers, beginning with “Truth” in 1959, Michael Dummett challenged the position that the classical notion of truth-condition occupied as the central notion of a theory of (...) meaning, and proposed that it should be replaced by the anti-realist (and intuitionistic) notion of assertability-condition. Taken together with normalization results obtained by Dag Prawitz, Dummett’s work truly opened up the anti-realist challenge at the level of proof-theoretical semantics.2 There has been since numerous rejoinders from partisans of classical logic, which were at times met with by attempts at watering down the anti-realist challenge, e.g., by arguing that anti-realism does not necessarily entail the adoption of intuitionistic logic. Only a few anti-realists, such as Crispin Wright and Neil Tennant, tried to look instead in the other direction, towards a more radical version of anti-realism which would entail deeper revisions of classical logic than those recommended by intuitionists.3 In this paper, which is largely programmatic, we shall also argue in favour of a radical anti-realism which would be a genuine alternative to the traditional anti-realism of Dummett and Prawitz. The debate about anti-realism has by now more or less run out of breath and we wish to provide it with a new lease on life, by taking into account the profound changes that took place in proof theory during the intervening years. We have in mind in particular the considerable development within Gentzen-style proof theory of non-classical, substructural logics other than intuitionistic logic, which seriously opens up the possibility that anti-realism, when properly understood, might end up justifying another logic, and the development of closer links between proof theory and computational complexity theory that has renewed interest in a radical form of anti-realism, namely strict finitism.

This essay characterizes a version of internal realism. In §1 I will argue that for semantical reasons we should be realists of a strong kind. In §2 I plead for an internalistic setting of realism starting from the thesis that truth is, at least, not a non-epistemic concept. We have to bear the consequences of this in form of a more complicated concept of truth. The ‘internal’ of ‘internal realism’ points to the justification aspect of truth. The ‘realism’ of ‘internal (...) realism’ points to the correspondence aspect. A thesis concerning the irreducibility of the two aspects will be established in §3. (shrink)

Many philosophers insist that moral facts or properties play no role in explaining (non-normative) natural phenomena. The problem of moral explanation has raised metaphysical, semantic and epistemic challenges to contemporary moral realism. In my dissertation, I attempt to vindicate the explanatory efficacy of moral properties, while at the same time respecting the autonomy and normativity of morality. In doing so, I will advocate a sort of non-reductive ethical naturalism, according to which moral properties are natural properties (in the sense that (...) they are open to empirical investigation), and yet remain irreducible to non-normative natural properties, such as psychological, biological, and sociological properties. More specifically, I develop a form of moral functionalism to vindicate moral explanation. Moral functionalism understands moral properties as second-order, functional properties, the natures of which are characterized in terms of functional roles. My version of moral functionalism has two particular features. First, it is a form of a posteriori moral functionalism. The moral theory used to characterize the functional roles of moral properties can only be discovered by appeal to empirical investigation (for this reason, my a posteriori version of moral functionalism is a sort of ethical naturalism). Second, it is a holistic version of moral functionalism. The functional role of a moral property cannot be identified solely in terms of non-normative properties; rather, it essentially involves a network of connections to both non-normative and normative properties (for this reason, my holistic version of moral functionalism is a sort of ethical anti-reductionism). It is important to note that the question of whether moral properties have explanatory power bears on the question of what explanation or explanatoriness is. In my dissertation, I attempt to show that my vindication of moral explanation presupposes a plausible account of explanation. Obviously I cannot discuss all theories of explanation; my dissertation will rather focus on two influential accounts of explanation: the causalist model and the unificationist model. Then I argue that moral properties understood as functional properties of the kind I have described can do causal-explanatory work and play a distinctive unifying role. (shrink)

Stephen Ingram defends a robustly realistic metaethical theory, based on the concept of normative arbitrariness, of which he provides the first in-depth analysis. He argues that, in order to capture the normative non-arbitrariness of moral choice, we must commit to the existence of robustly stance-independent, categorical, irreducibly normative, non-natural moral facts. Specifically, he identifies five ways in which a metaethical theory might fail to capture the non-arbitrariness of moral choice. The first involves claims about the bruteness of moral attitudes or (...) facts. The second involves claims about the privileging of some attitudes over others. The third involves the claim that some metaethical theories leave a normative deficit. The fourth involves a claim about our ownership over moral reality. And the fifth involves the claim that certain metaethical theories introduce a destabilising contingency into the moral domain. Ingram argues that robust realism is the theory that is best placed to avoid all five of these arbitrariness charges. He then goes on to show that, by exploring the nature of interpersonal moral dialogue, robust realists can defend epistemological and meta-semantic theories that are friendly to their view. Specifically, he defends a dualistic form of moral intuitionism on which some moral beliefs are justified on the basis of a priori intuitions, whilst others are justified on the basis of a posteriori moral experiences, and provides a theory of 'moral mental files' to explain how moral terms and concepts are able to refer to robust moral facts.

The aim of this paper is twofold: (1) to assess whether the construct of neural representations plays an explanatory role under the variational free-energy principle and its corollary process theory, active inference; and (2) if so, to assess which philosophical stance - in relation to the ontological and epistemological status of representations - is most appropriate. We focus on non-realist (deflationary and fictionalist-instrumentalist) approaches. We consider a deflationary account of mental representation, according to which the explanatorily relevant contents of (...) neural representations are mathematical, rather than cognitive, and a fictionalist or instrumentalist account, according to which representations are scientifically useful fictions that serve explanatory (and other) aims. After reviewing the free-energy principle and active inference, we argue that the model of adaptive phenotypes under the free-energy principle can be used to furnish a formal semantics, enabling us to assign semantic content to specific phenotypic states (the internal states of a Markovian system that exists far from equilibrium). We propose a modified fictionalist account: an organism-centered fictionalism or instrumentalism. We argue that, under the free-energy principle, pursuing even a deflationary account of the content of neural representations licenses the appeal to the kind of semantic content involved in the aboutness or intentionality of cognitive systems; our position is thus coherent with, but rests on distinct assumptions from, the realist position. We argue that the free-energy principle thereby explains the aboutness or intentionality in living systems and hence their capacity to parse their sensory stream using an ontology or set of semantic factors.

Both formal semantics and cognitive semantics are the source of important insights about language. By developing precise statements of the rules of meaning in fragmentary, abstract languages, formalists have been able to offer perspicuous accounts of how we might come to know such rules and use them to communicate with others. Conversely, by charting the overall landscape of interpretations, cognitivists have documented how closely interpretations draw on the commonsense knowledge that lets us make our way in the world. There is (...) no opposition between these insights. Sooner or later we will have a semantics that responds to both. However, developing such a semantics is profoundly difficult, because there are certain tensions to be overcome in reconciling the two perspectives. For one thing, the overall landscape of meaning does seem to be characterized by a much richer ontology and more dynamic categories than are exhibited by the fragments typically studied in the formal tradition. One sign of strain is the recent tendency to talk of “procedural”, “non-compositional”, or “computational” semantics, as in Hamm, Kamp and van Lambalgen 2006, hereafter HK&vL. We think such locutions can serve as useful reminders to keep semantics fixed on the central question of how language allows us to share information that some have and others need to get. However, there is some danger that formalists will merely by put off by an idea that, taken literally, may not be such a good one. In this short article, we want to explore and defend the traditional realist view attributed by HK&vL to Lewis among others. In fact, this view offers a well-developed, extremely straightforward and robust account of the relation between semantics and cognition. Moreover, while the realist view has ways of accommodating the representationalist insights of DRT (Lewis 1979; Thomason 1990; Stalnaker 1998), it remains unclear how “computational” semantics can account for the key data for the realist view: cases where we judge interlocutors to be ignorant about aspects of meaning in their native language (Kripke 1972; Putnam 1975; Stalnaker 1979; Williamson 1994)..

The decision whether to have a realist or an anti-realist attitude towards scientific hypotheses is interpreted in this paper as a choice that scientists themselves have to face in their work as scientists, rather than as a ‘philosophical’ problem. Scientists’ choices between realism and instrumentalism (or other types of anti-realism) are interpreted in this paper with the help of two different conceptual tools: a deflationary semantics grounded in the inferentialist approach to linguistic practices developed by some authors (e.g., (...) Sellars, Brandom), and an epistemic utility function that tries to represent the cognitive preferences of scientists. The first tool is applied to two different questions traditionally related to the problem of scientific realism: the non-miracle argument, and the continuity of reference. The second one is applied to the problem of unconceived alternatives, and to the distinction between realist and instrumentalist attitudes towards scientific hypotheses. (shrink)

This paper defends pro-realism, the view that it is better if moral realism is true rather than any of its rivals. After offering an account of philosophical angst, I make three general arguments. The first targets nihilism: in securing the possibility of moral justification and vindication in objecting to certain harms, moral realism secures something that is non-morally valuable and even essential to the meaning and intelligibility of our lives. The second argument targets antirealism: moral realism secures a desirable independence (...) for moral justification that is qualitatively different from the anti-realistic construal of independence that is only explicable in terms of degrees of distance from our subjective responses and attitudes. Finally, I argue that while the pan-expressivist semantic program of quasi-realism has significant effects on what can be appropriately said in meta-ethical discourse, it provides no comfort to the pro-realist who is already angsty about anti-realism.

Buddhist semantic realists assert that reality is always non-linguistic, beyond the domain of conceptual thought. Anything that is conceptual and linguistic, they maintain, cannot be reality and therefore cannot function as reality.The Pra¯san˙gika however rejects the realist theory and argues that all realities are purely linguistic—just names and concepts—and that only linguistic reality can have any causal function. This paper seeks to understand the Pra¯san˙gika’s radical semantic nominalism and its philosophical justifications by comparing and contrasting it with the realistic (...) semantic theories.

I propose a novel hyperintensional semantics for belief revision and a corresponding system of dynamic doxastic logic. The main goal of the framework is to reduce some of the idealisations that are common in the belief revision literature and in dynamic epistemic logic. The models of the new framework are primarily based on potentially incomplete or inconsistent collections of information, represented by situations in a situation space. I propose that by shifting the representational focus of doxastic models from belief sets (...) to collections of information, and by defining changes of beliefs as artifacts of changes of information, we can achieve a more realistic account of belief representation and belief change. The proposed dynamic operation suggests a non-classical way of changing beliefs: belief revision occurs in non-explosive environments which allow for a non-monotonic and hyperintensional belief dynamics. A logic that is sound with respect to the semantics is also provided. (shrink)

Context: Although Josef Mitterer’s non-dualism has received increasing attention in recent years, it is still underrated by philosophers. It is an ambitious and unusual treatment of epistemological problems concerning truth and reality. Problem: Is non-dualism tenable? Is conceptual relativism tenable? Method: On the basis of a pragmatic semantics, Mitterer’s arguments against conceptual relativism are shown to be unjustified. Results: Non-dualism lacks a clear conception of semantics. Given the similarities to Robert Brandom’s account of truth, as well as Mitterer’s preoccupation with (...) Wittgenstein, pragmatic semantics suggests itself for filling this gap. But then conceptual relativism seems to be the more attractive position. Implications: This paper is a critical survey of non-dualism and a defense of conceptual relativism, but it might also be a worthwhile reading for those interested in semantic issues such as the difference between Ludwig Wittgenstein’s and Robert Brandom’s approaches to “meaning as use.” Constructivist content: Non-dualism is sometimes regarded as an alternative to realistic and constructivist positions in epistemology. This paper, however, defends conceptual relativism, which is a kind of realism that can also be seen as a kind of (non-radical) constructivism. (shrink)

This paper explores how realism is crucial in understanding rule-following. The strategy involves starting from what has been achieved by Wittgenstein and others as regards semantic normativity and then applying it to other areas, including moral deliberation. The result shows that realism in rule-following involves not only the weak claim that rules are independent of the individual rule-follower, as conventions are. It involves also the stronger claim that conventional rules are constrained by non-conventional constraints. These constraints depend neither on the (...) individual nor on the group. They arise from the nature of things. Human rule-followers are constrained first by being material beings, secondly by being living organisms, and thirdly by being rational. (shrink)

Realism as an explanatory theory of science (faded realism) is not convincing. However, neither "internal realism" nor instrumentalism are plausible. Assuming common sense realism a non-explanatory form of scientific realism (modest realism) can be defended. Modest realism has affinities with Fine's NOA. To NOA it adds a descriptive thesis about scientific progress towards truth or verisimilitude. In addition it adds a concern with purely philosophical issues which arise in reflections on the nature of science. However, there is little to say (...) about truth over and above what is conveyed by Tarski/Davidson semantics. (shrink)

The article examines the peculiarities of the approach of speculative realism to the analysis of the concepts of existence and object in the context of its criticism of Kantian and post-Kantian ontology, and especially the concept of correlationism, the dependence of the existence of objects on the perception of subjects, i.e. the postulation of the impossibility of the existence of the objective and the independent world from a man. The reasons for the emergence of speculative realism in contemporary French and (...) English philosophy and why these philosophies are called post-continental philosophies are clarified with the help of the historical-comparative method and the method of analysis. In opposition to correlationism, speculative realism seeks to “break through” to a “non-human world,” that is, to a world that is non-anthropocentric and non-human-dimensional. Such a world would be, in fact, “alien” to man, because it would be filled with objects unknown to man and independent of him. Here the obvious goal of speculative realism is to grant freedom to objects through the destruction of correlationism.In addition, the article shows that speculative realism, as a phenomenon in contemporary philosophy, is not homogeneous. Object-oriented ontology, speculative materialism, and materialist phenomenology can be distinguished in it. All these sub-ontologies of speculative realism demonstrate semantic shifts in the understanding of object and existence, but they recognize the existence of objective reality or the reality of objects, regardless of what they mean by the latter, which they try to ground it, in order to give it a fundamental meaning. Therefore, common for these sub-ontologies is the name “speculative” or “metaphysical” realism. (shrink)

This paper defends the view that common nouns have a dual semantic structure that includes extension-determining and non-extension-determining components. I argue that the non-extension-determining components are part of linguistic meaning because they play a key compositional role in certain constructions, especially in privative noun phrases such as "fake gun" and "counterfeit document". Furthermore, I show that if we modify the compositional interpretation rules in certain simple ways, this dual content account of noun phrase modification can be implemented in a type-driven (...) formal semantic framework. In addition, I also argue against traditional accounts of privative noun phrases which can be paired with the assumption that nouns do not have a dual semantic structure. At the most general level, this paper presents a proposal for how we can begin to integrate a psychologically realistic account of lexical semantics with a linguistically plausible compositional semantic framework.

The philosophy of mathematical practice sometimes investigates the social constitution of mathematics but does not always make explicit the philosophical-normative framework that guides the discussion. This chapter investigates some recent proposals in the philosophy of mathematical practice that compare social facts and mathematical objects, discussing similarities and differences. An attempt will be made to identify, through a comparison with three different perspectives in social ontology, the kind of objectivity attributed to mathematical knowledge, the type of representational or non-representational semantics adopted, (...) and the justificatory or coordinative role entrusted to axiomatics. After a brief introduction to key issues in social ontology, Sect. 3 of the chapter offers a survey of contributions by Feferman, Ferreirós, and Cole, highlighting a difference between approaches based on rules, practices, and intentional states, respectively. Section 4.1 also discusses results by Carter, Collin, Giardino, and Pantsar, focusing on differences between the objectivity of knowledge and objectivity of objects and showing that many authors combine a realist, structuralist, and pragmatist perspective, as well as the idea that objectivity comes in degrees. Section 4.2 focuses on the kind of semantics that is adopted in socially oriented approaches. A representational semantics is preferred by authors grounding their views on mental states, whereas a non-representational semantics best fits with views based on practices. Section 5 considers how axiomatics can be understood in a social perspective. Axiomatics generally plays a justificatory role also in theories that aim to explain the social constitution of mathematical knowledge. Yet, if one shifts from approaches based on mental states to approaches anchored on rules or habits, axiomatics can be viewed as an institution based on obligations, functions, coordination problems, and agent’s actions and roles, thus playing an organizational and coordination role.

We examine Paul Halmos’ comments on category theory, Dedekind cuts, devil worship, logic, and Robinson’s infinitesimals. Halmos’ scepticism about category theory derives from his philosophical position of naive set-theoretic realism. In the words of an MAA biography, Halmos thought that mathematics is “certainty” and “architecture” yet 20th century logic teaches us is that mathematics is full of uncertainty or more precisely incompleteness. If the term architecture meant to imply that mathematics is one great solid castle, then modern logic tends to (...) teach us the opposite lesson, namely that the castle is floating in midair. Halmos’ realism tends to color his judgment of purely scientific aspects of logic and the way it is practiced and applied. He often expressed distaste for nonstandard models, and made a sustained effort to eliminate first-order logic, the logicians’ concept of interpretation, and the syntactic vs semantic distinction. He felt that these were vague, and sought to replace them all by his polyadic algebra. Halmos claimed that Robinson’s framework is “unnecessary” but Henson and Keisler argue that Robinson’s framework allows one to dig deeper into set-theoretic resources than is common in Archimedean mathematics. This can potentially prove theorems not accessible by standard methods, undermining Halmos’ criticisms. (shrink)

This is the second in a sequence of three essays which axiomatize and apply Edmund Husserl's dependence ontology of parts and wholes as a non-Diodorean, non-Kantian temporal semantics for first-order predicate modal languages. The Ontology of Intentionality I introduced enough of Husserl's dependence-ontology of parts and wholes to formulate his account of order as effected by relating moments of unity, and The Ontology of Intentionality II extends that axiomatic dependence-ontology far enough to enable its semantic application. Formalizing the compatibility [Vereinbarkeit] (...) relation implicated in Husserl's notorious doctrine of impossible meanings, the essay introduces a compatibility restriction on relations to formulate Husserl's distinction between singular [einheitliche] and plural [mehrheitliche] objects, using plural relating moments to define first-order versions of Husserl's notions of relation complexes (i.e. Sachverhalte), abstracta of n-ary relation complexes, categorial relations, abstract eide as unifications of categorial relations, semantic domains as completions of abstract eide, and material regions as semantic domains which are compatibility upper bounds of categorial relations. These concepts will enable the formal dependence-ontological noetic semantics for two-valued, first-order modal languages introduced in the sequel Two-Valued Logics of Intentionality, the third essay in the sequence.

In her book Fiction and Metaphysics (1999) Amie Thomasson, influenced by the work of Roman Ingarden, develops a phenomenological approach to fictional entities in order to explain how non-fictional entities can be referred to intrafictionally and transfictionally, for example in the context of literary interpretation. As our starting point we take Thomasson’s realist theory of literary fictional objects, according to which such objects actually exist, albeit as abstract and artifactual entities. Thomasson’s approach relies heavily on the notion of ontological (...) dependence, but its precise semantics has not yet been developed. Moreover, the modal approach to the notion of ontological dependence underlying the Artifactual Theory has recently been contested by several scholars. The main aims of this paper are (i) to develop a semantic approach to the notion of ontological dependence in the context of the Artifactual Theory of fiction, and in so doing bridge a number of philosophical and logical gaps; (ii) to generalize Thomasson’s categorial theory of ontological dependence by reconstructing ontological categories of entities purely in terms of different structures of ontological dependence, rather than in terms of the basic kinds of entities the categorical entities depend on.

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.

This essay deals with the concept of truth in the context of a version of internal realism . In §1 I define some variants of realism using a set of realistic axioms. In §2 I will argue that for semantical reasons we should be realists of some kind. In §3 I plead for an internalistic setting of realism starting from the thesis that truth is, at least, not a non-epistemic concept. We have to bear the consequences of this in form (...) of a more complicated concept of truth. The "internal" of "internal realism" points to the justification aspect of truth. The "realism" of "internal realism" points to the correspondence aspect. A thesis concerning the irreducibility of the two aspects will be established in §4. (shrink)

The old Bohr–Einstein debate about the completeness of quantum mechanics (QM) was held on an ontological ground. The completeness problem becomes more tractable, however, if it is preliminarily discussed from a semantic viewpoint. Indeed every physical theory adopts, explicitly or not, a truth theory for its observative language, in terms of which the notions of semantic objectivity and semantic completeness of the physical theory can be introduced and inquired. In particular, standard QM adopts a verificationist theory of truth that implies (...) its semantic nonobjectivity; moreover, we show in this paper that standard QM is semantically complete, which matches Bohr's thesis. On the other hand, one of the authors has provided a Semantic Realism (or SR) interpretation of QM that adopts a Tarskian theory of truth as correspondence for the observative language of QM (which was previously mantained to be impossible); according to this interpretation QM is semantically objective, yet incomplete, which matches EPR's thesis. Thus, standard QM and the SR interpretation of QM come to opposite conclusions. These can be reconciled within an integrationist perspective that interpretes non-Tarskian theories of truth as theories of metalinguistic concepts different from truth. (shrink)

Aldo Antonelli offers a novel view on abstraction principles in order to solve a traditional tension between different requirements: that the claims of science be taken at face value, even when involving putative reference to mathematical entities; and that referents of mathematical terms are identified and their possible relations to other objects specified. In his view, abstraction principles provide representatives for equivalence classes of second-order entities that are available provided the first- and second-order domains are in the equilibrium dictated by (...) the abstraction principles, and whose choice is otherwise unconstrained.entities are the referents of abstraction terms: such referents are to an extent indeterminate, but we can still quantify over them, predicate identity or non-identity, etc. Our knowledge of them is limited, but still substantial: we know whatever has to be true no matter how the representatives are chosen, i.e., what is true in all models of the corresponding abstraction principles. This view is backed up by an “austere” conception of universals, according to which these are first-order objects, i.e., ways of collecting first-order objects. Antonelli thus claims that second-order logic does not import any novel ontological commitment beyond ontology of first-order, naturalistically acceptable, objects. Moreover, in the case of arithmetic, even if Hume’s Principle is construed as described above, Frege’s Theorem goes through unaffected, since there is nothing in its proof that depends on an account of the “true nature” of numbers. A viable construal of logicism is then given by the combination of semantic nominalism and a naturalistic conception of abstraction. [Editors note]. (shrink)
