Theories of partial reference have been developed in order to retrospectively interpret rather stubborn past scientific theories like Newtonian dynamics and the phlogiston theory in a realist way, i.e., as approximately true. This is done by allowing for a term to refer to more than one entity at the same time and by providing semantic structures that determine the truth values of sentences containing partially referring terms. Two versions of theories of partial reference will be presented, (...) a conjunctive (by Hartry Field, 1973) and a disjunctive one (by Christina McLeish, 2006). In this paper, I will analyze them with regard to modal and epistemic aspects of those theories. It will be argued that a) theories of partial reference are (surprisingly) compatible with the rigidity of natural kind terms but face a weaker form of the so called “no-failures-of-reference-problem” and b) that the disjunctive account of partial reference suffers from a serious weakness: the impossibility of discriminating between descriptions that fix the reference of a term and those merely associated with it leads to the unacceptable result that past scientific theories containing such partially referring terms will come out as epistemically necessary, i.e., as a priori true.

The interpretation of the concept of reduced state is a subtle issue that has relevant consequences when the task is the interpretation of quantum mechanics itself. The aim of this paper is to argue that reduced states are not the quantum states of subsystems in the same sense as quantum states are states of the whole composite system. After clearly stating the problem, our argument is developed in three stages. First, we consider the phenomenon of environment-induced decoherence as an example (...) of the case in which the subsystems interact with each other; we show that decoherence does not solve the measurement problem precisely because the reduced state of the measuring apparatus is not its quantum state. Second, the non-interacting case is illustrated in the context of no-collapse interpretations, in which we show that certain well-known experimental results cannot be accounted for due to the fact that the reduced states of the measured system and the measuring apparatus are conceived as their quantum states. Finally, we prove that reduced states are a kind of coarse-grained states, and for this reason they cancel the correlations of the subsystem with other subsystems with which it interacts or is entangled.

This paper elaborates on the following correspondence theorem (which has been defended and formally proved elsewhere): if theory T has been empirically successful in a domain of applications A, but was superseded later on by a different theory T* which was likewise successful in A, then under natural conditions T contains theoretical expressions which were responsible for T’s success and correspond (in A) to certain theoretical expressions of T*. I illustrate this theorem at hand of the phlogiston versus oxygen theories (...) of combustion, and the classical versus relativistic theories of mass. The ontological consequences of the theorem are worked out in terms of the indirect reference and partial truth. The final section explains how the correspondence theorem may justify a weak version of scientific realism without presupposing the no-miracles argument. (shrink)

There is a duality in our everyday view of belief. On the one hand, we sometimes speak of credence as a matter of degree. We talk of having some level of confidence in a claim (that a certain course of action is safe, for example, or that a desired event will occur) and explain our actions by reference to these degrees of confidence – tacitly appealing, it seems, to a probabilistic calculus such as that formalized in Bayesian decision theory. (...) On the other hand, we also speak of belief as an unqualified, or flat-out, state (‘plain belief’ as it is sometimes called), which is either categorically present or categorically absent. We talk of simply believing or thinking that something is the case, and we cite these flat-out attitudes in explanation of our actions – appealing to classical practical reasoning of the sort formalized in the so-called ‘practical syllogism’.1 This tension in everyday discourse is reflected in the theoretical literature on belief. In formal epistemology there is a division between those in the Bayesian tradition, who treat credence as graded, and those who think of it as a categorical attitude of some kind. The Bayesian perspective also contrasts with the dominant view in philosophy of mind, where belief is widely regarded as a categorical state (a token sentence of a mental language, inscribed in a functionally defined ‘belief box’, according to one popular account). A parallel duality is present in our everyday view of desire. Sometimes we talk of having degrees of preference or desirability; sometimes we speak simply of wanting or desiring something tout court, and, again, this tension is reflected in the theoretical literature. What should we make of these dualities? Are there two different types of belief and desire – partial and flat-out, as they are sometimes called? If so, how are they related? And how could both have a role in guiding rational action, as the everyday view has it? The last question poses a particular challenge in relation to flat-out belief and desire.. (shrink)

This paper explores the scientific viability of the concept of causality—by questioning a central element of the distinction between “fundamental” and non-fundamental physics. It will be argued that the prevalent emphasis on fundamental physics involves formalistic and idealized partial models of physical regularities abstracting from and idealizing the causal evolution of physical systems. The accepted roles of partial models and of the special sciences in the growth of knowledge help demonstrate proper limitations of the concept of fundamental physics. (...) We expect that a cause precedes its effect. But in some tension with this point, fundamental physical law is often held to be symmetrical and all-encompassing. Physical time, however, has not only measurable extension, as with spatial dimensions, it also has a direction—from the past through the present into the future. This preferred direction is time’s arrow. In spite of this standard contrast of time with space, if all the fundamental laws of physics are symmetrical, they are indifferent to time’s arrow. In consequence, excessive emphasis on the ideal of symmetrical, fundamental laws of physics generates skepticism regarding the common-sense and scientific uses of the concept of causality. The expectation has been that all physical phenomena are capable of explanation and prediction by reference to fundamental physicals laws—so that the laws and phenomena of statistical thermodynam- ics —and of the special sciences—must be derivative and/or secondary. The most important and oft repeated explanation of time’s arrow, however, is provided by the second law of thermodynamics. This paper explores the prospects for time’s arrow based on the second law. The concept of causality employed here is empirically based, though acknowledging practical scientific interests, and is linked to time’s arrow and to the thesis that there can be no causal change, in any domain of inquiry, without physical interaction.

At the outset of the Republic, Polemarchus advances the bold thesis that “justice is the art which gives benefit to friends and injury to enemies”. He quickly rejects the hypothesis, and what follows is a long tradition of neglecting the ethics of enmity. The parallel issue of how friendship affects the moral sphere has, by contrast, been greatly illuminated by discussions both ancient and contemporary. This article connects this existing work to the less explored topic of the normative significance of (...) our negative relationships. I explain how negative partiality should be conceptualized through reference to the positive analogue, and argue that at least some forms of negative partiality are justified. I further explore the connection between positive and negative relationships by showing how both are justified by ongoing histories of encounter. However, I also argue that these relationships are in some important ways asymmetrical. (shrink)

This article points out problems in current dynamic treatments of anaphora and provides a new account that solves these by grafting Muskens' Compositional Discourse Representation Theory onto a partial theory of types. Partiality is exploited to keep track of which discourse referents have been introduced in the text (thus avoiding the overwrite problem) and to account for cases of anaphoric failure. Another key assumption is that the set of discourse referents is well-ordered, so that we can keep track of (...) the order in which they have been introduced, allowing a semantic characterization of anaphoric accessibility across stretches of discourse. Unlike other dynamic approaches, the system defines semantic values for unresolved anaphors. This leads to a clear separation of monotonic and non-monotonic content (in this case anaphoric resolution) and arguably provides a sound basis for a non-monotonic theory of anaphoric resolution.

This paper examines causal theories of reference with respect to how plausible an account they give of non-physical natural kind terms such as ‘gene’ as well as of the truth of the associated theoretical claims. I first show that reference fixism for ‘gene’ fails. By this, I mean the claim that the reference of ‘gene’ was stable over longer historical periods, for example, since the classical period of transmission genetics. Second, I show that the theory of (...) class='Hi'>partial reference does not do justice to some widely held realist intuitions about classical genetics. This result is at loggerheads with the explicit goals usually associated with partial theories of reference, which is to defend a realist semantics for scientific terms. Thirdly, I show that, contrary to received wisdom and perhaps contrary to physics and chemistry, neither reference fixism nor partial reference are necessary in order to hold on to scientific realism about biology. I pinpoint the reasons for this in the nature of biological kinds, which do not even remotely resemble natural kinds (i.e., Lockean real essences) as traditionally conceived. (shrink)

Theories of moral desert focus only on the personal culpability of the agent to determine the amount of blame and punishment the agent deserves. I defend an alternative account of desert, one that does not focus only facts about offenders and their offenses. In this revised framework, personal culpability can do no more than set upper and lower limits for deserved blame and punishment. For more precise judgments within that spectrum, additional factors must be considered, factors that are independent of (...) the agent and the offense. I refer to this as the ‘partial conception’ of desert because takes facts about victims—their behavior, desires, and attitudes—into account for desert judgments. On my view, then, agents who are equally culpable may deserve different amounts of blame or punishment, depending on these victim-related factors. (shrink)

This essay counteracts that trend [regarding the debate about whether partiality can be justified, those supporting impartiality have generally been on the offensive arguing that morality calls for impartiality] by taking a closer look at the moral complexity of our social practices of partiality. My adoption of this approach does not represent an endorsement of current notions of impartiality. The ideal of impartiality, in my view, should be substantially reformulated. However, that the concept of partiality is transparently defensible. In this (...) discussion, I focus on the aspects of partiality that complicate the philosophical defense of it. In the first part of the discussion, I argue that the moral value of partiality depends partly on the moral value of the relationships it helps to sustain. It matters to the philosophical issues at stake that personal relationships can be abusive and oppressive. In Section II, I refer to the vastly unequal social distribution of the means for favoring loved ones. Because many people have inadequate resources for caring for their loved ones, our conventional relationship practices of partiality-practices by which we care only for our ``own''-can be disasterous for many people. This seriously complicates the defense of partiality. The paper ends with a discussion, in Section III, of ``global moral concern'' and the resistance which most partialists show to it. (shrink)

As they are conventionally formulated, Boolean games assume that players make their choices in ignorance of the choices being made by other players – they are games of simultaneous moves. For many settings, this is clearly unrealistic. In this paper, we show how Boolean games can be enriched by dependency graphs which explicitly represent the informational dependencies between variables in a game. More precisely, dependency graphs play two roles. First, when we say that variable x depends on variable y, then (...) we mean that when a strategy assigns a value to variable x, it can be informed by the value that has been assigned to y. Second, and as a consequence of the first property, they capture a richer and more plausible model of concurrency than the simultaneous-action model implicit in conventional Boolean games. Dependency graphs implicitly define a partial ordering of the run-time events in a game: if x is dependent on y, then the assignment of a value to y must precede the assignment of a value to x; if x and y are independent, however, then we can say nothing about the ordering of assignments to these variables—the assignments may occur concurrently. We refer to Boolean games with dependency graphs as partial-order Boolean games. After motivating and presenting the partial-order Boolean games model, we explore its properties. We show that while some problems associated with our new games have the same complexity as in conventional Boolean games, for others the complexity blows up dramatically. We also show that the concurrency in partial-order Boolean games can be modelled using a closure-operator semantics, and conclude by considering the relationship of our model to Independence-Friendly logic.

Based on da Costa's and French's notions of partial structures and pragmatic truth, this paper examines two possible characterizations of the concept of empirical adequacy, one depending on the notion of partial isomorphism, the other on the hierarchy of partial models of phenomena, and both compatible with an empiricist view. These formulations can then be employed to illuminate certain aspects of scientific practice.An empirical theory must single out a specific part of the world, establish reference to (...) that part, and say—by way of contingent, substantial claim about the world—that its models fit that. Now, how exactly can this be done? Bas C. van Fraassen. (shrink)

Hartry Field, Jerry Fodor and others differ with Donald Davidson over the question of how a theory of content should be structured. Field and Fodor maintain that a theory should begin by following the compositional structure of a sentence in reducing the semantic properties of complex expressions to the semantic properties of their simplest parts and complete the job by reducing the semantic properties of the parts to non-semantic ones. Davidson describes this approach as the ‘Building-Block method’ and maintains that (...) it cannot possibly succeed. He holds that a theory of content should ‘give up reference’ by treating the semantic properties of basic expressions as a purely technical devices with no direct relation to non-semantic phenomenon. In this essay, I examine what I call “Davidson’s Dilemma”, the conflict between the apparent soundness the arguments for the view that a theory must treat reference as a point where linguistic and non-linguistic reality meet and the equally apparent soundness his argument that reference cannot possibly play this role. I propose a resolution to the dilemma that grants the validity of Davidson’s arguments against the building-block theories but is, I believe, more palatable to mainstream semanticists than Davidson’s solution. This solution, which I call ‘content partialism’ treats the reference of terms as regularities across propositional contents. I show how content partialism is consistent with a Kripkean theory of reference fixing, the touchstone of those who advocate building-block theories. (shrink)

Presenting a novel account of singular thought, a systematic application of recent work in the theory of speech acts, and a partial revival of Russell's analysis of singular terms, this book takes an original approach to the perennial problems of reference and singular terms by separating the underlying issues into different levels of analysis.

Since universal language systems are confronted with serious paradoxical consequences, a semantic approach is developed in whichpartial worlds form the ontological basis. This approach shares withsituation semantics the basic idea that statements always refer to certain partial worlds, and it agrees with the extensional and model-theoretic character ofpossible worlds semantics. Within the framework of the partial worlds conception a satisfactory solution to theLiar paradox can be formulated. In particular, one advantage of this approach over those theories that are (...) based on the totality of possible worlds semantics can be found in the fact that the so-called Strengthened Liar problem is avoided.

One of the advantages of my account in the essay “Instantiation as Partial Identity” was capturing the contingency of instantiation—something David Armstrong gave up in his experiment with a similar view. What made the contingency possible for me was my own non-standard account of identity, complete with the apparatus of counts and aspects. The need remains to lift some obscurity from the account in order to display its virtues to greater advantage. To that end, I propose to respond to (...) those who have grappled with it in print. There are various criticisms by commentators: that it is rendered absurd by the transitivity of identity, that it makes instantiation necessary instead of contingent, that it is unclear what counts are, that aspects are simply tropes, that my view does not capture multiple location, that I make an unclear reference to a theory of composition as identity, that the account suffers from problems with polyadicity, and that it is not a realist account of universals after all. I give responses to these objections. (shrink)

Lewisian reference magnetism about linguistic content determination [Lewis 1983 has been defended in recent work by Weatherson [2003] and Sider [2009], among others. Two advantages claimed for the view are its capacity to make sense of systematic error in speakers' use of their words, and its capacity to distinguish between verbal and substantive disagreements. Our understanding of both error and disagreement is linked to the role of usage and first order intuitions in semantics and in linguistic theory more generally. (...) I argue, partially on the basis of these more general considerations, that reference magnetism delivers implausible results. Specifically, I argue that the proponent of reference magnetism maintains her analysis of genuinely systematic error at the cost of an empirically unjustifiable error theory regarding ordinary usage. In response, I describe an alternative view of content determination—MUMPS, or Meaning is Use Minus Pragmatics—which is not committed to such error theories. Despite this advantage, MUMPS has high prima facie costs. On such a view, there is a great deal of variation in linguistic meaning across speakers and times. As a result, a large number of seemingly mistaken claims are analysed as expressing true propositions. Correspondingly, a large number of seemingly substantive disagreements are analysed as terminological. However, I argue that these consequences are not as costly as they seem. Despite appearances, MUMPS is consistent with objective, metaphysically realist adjudication of disagreements, even in cases where meanings are not shared and where both parties to a dispute speak truly. MUMPS thus allows for a more nuanced understanding of linguistic usage, change, and variation, without imposing a commitment to any form of metaphysical anti-realism. (shrink)

This paper begins by affirming the view that if there is a debate to be had over whether literature can convey moral knowledge, then efforts by proponents to substantiate this claim will already be necessarily conditioned by an understanding of what morality consists in, independently of literature. This observation brings to light a certain danger for the debate, namely that if participants fail to explicitly specify the ethical theory that they rely on, then the debate can seem nebulous. This raises (...) a new question: is there an account of morality, independent of literature, which is most conducive to literary moral cognitivism, that is, which optimises literary moral cognitivism's chances of succeeding philosophically? This paper both formulates and investigates this hypothesis with reference to moral pluralism, the view that there is an irreducible plurality of foundational moral principles. It concludes that such an affinity exists, but with an important caveat: the affinity is stronger at the level of moral suggestion than the level of moral justification. This has implications for the strength of the version of literary moral cognitivism that it is ultimately plausible to endorse from a moral pluralist point of view. (shrink)

Recently there has been a surge of new Fregeans who claim that the direct designation theory, as understood by contemporary Russellians, does not, and cannot, account for the different cognitive significance of statements containing different but codesignative names or indexicals. Instead, they say we must use a fine grained notion of propositions; one which builds a mode of presentation into proposition in addition to including in them the object referred to by the name or indexical in the sentence expressing the (...) proposition. Thus we have Mark Richard, John Perry, and Mark Crimmins championing theories that build the mode of presentation into propositions, making the mode of presentation affect the truth conditions of belief reports. What is interesting, though, is that all three accept the direct designationalists claim that proper names, indexicals, and demonstratives are directly referential.I present four problems for the direct designation theorists and argue that the problem the new Fregeans use to motivate their move to include cognitive significance in propositions is the least basic of the four problems. I then provide an account of beliefs of singular propositions which does not require us to build modes of presentations into propositions and which solves the problems posed for the direct designation theory.

Compatibilism is the view that free will can exist even if determinism — the thesis that there is only one physically possible future at any given time — is true. In this thesis, I defend compatibilism by arguing against two of its main rivals. I first argue against necessary eliminativism — the view that free will is impossible — by deploying an attractive view of language (Lewis, 1983, 1984; Sider, 2001) to show that, so long as ordinary folk are liable (...) to experience conflicting intuitions about how to use the term ‘free,’ it will refer to some property which is possibly exemplified. I then argue that libertarians — believers in free will who hold that it is incompatible with determinism — must reject either a naturalistic view of the world with no ontological commitments above and beyond those proscribed by science or the soundness of the best argument in favor of libertarianism (van Inwagen, 1983, ch. 3). Finally, I sketch a way a proponent of compatibilism can use my arguments against necessary eliminativists and naturalistic libertarians to offer a positive argument for compatibilism. (shrink)

Frege and quine notwithstanding, Some singular terms in belief contexts have normal reference but do not admit truth-Preserving substitution of co-Referential terms. The conditions of a sentence's being true of a sequence of referents may be partially determined by its singular terms; substitution may change those conditions, While preserving genuine reference. On one reading, 'n believes that f is g' is true iff n believes of the f that it is the f and is g.

Robert Kraut has proposed an analogy between valuing a loved one as irreplaceable and the sort of “rigid” attachment that (according to Saul Kripke’s account) occurs with the reference of proper names. We wanted to see if individuals with Kripkean intuitions were indeed more likely to value loved ones (and other persons and things) as irreplaceable. In this empirical study, 162 participants completed an online questionnaire asking them to consider how appropriate it would be to feel the same way (...) about a perfect replica of a loved one, as well as other questions about replaceability. Participants who previously had endorsed Kripkean reference (n = 96) rated loved ones as less replaceable on two different measures than participants who had previously endorsed Descriptivist reference (n = 66, t(160)> 2.27, p <.02, eta2> .03). Additional results suggest that this difference extends to other targets as well and is at least partially dependent on sentimental attachment. (shrink)

Philosophers of language inspired by Grice have long sought to show how facts about reference boil down to facts about speakers’ communicative intentions. I focus on a recent attempt by Stephen Neale (2016), who argues that referring with an expression requires having a special kind of communicative intention—one that involves representing an occurrence of the expression as standing in some particular relation to its referent. Neale raises a problem for this account: because some referring expressions are unpronounced, most language (...) users don’t realize they exist, and so seemingly don’t have intentions about them. Neale suggests that we might solve this problem by supposing that speakers have nonconscious or “tacit” intentions. I argue that this solution can’t work by arguing that our representations of unpronounced bits of language all occur within a modular component of the mind, and so we can’t have intentions about them. From this line of thought, I draw several conclusions. (i) The semantic value of a referring expression is not its referent, but rather a piece of partial and defeasible evidence about what a speaker refers to when using it literally. (ii) There is no interesting sense in which speakers refer with expressions; referring expressions are used to give evidence about the sort of singular proposition one intends to communicate. (iii) The semantics–pragmatics interface is coincident with the interface between the language module and central cognition. (shrink)

A predicate of personal taste occurring in a sentence in which the perspectival information is not linguistically articulated by an experiencer phrase may have two different readings. In case the speaker of a bare sentence formed with a predicate of personal taste uses the subjective predicate encoding perspectival information in one way and the hearer interprets it in another way, the agents’ acts are not coordinated. In this paper I offer an answer to the question of how a hearer can (...) strategically interact with a speaker on the intended perspectival information so that both agents can optimally solve their coordination problem. In this sense, I offer a game-theoretical account of the strategic communication with expressions referring to agents’ perspectives, communication which involves the interaction between a speaker who intends to convey some perspectival information and who chooses to utter a bare sentence formed with a predicate of personal taste, instead of a sentence in which the perspectival information is linguistically articulated by an experiencer phrase, and a hearer who has to choose between interpreting the uttered sentence in conformity with the speaker’s autocentric use of the predicate of personal taste or in conformity with the speaker’s exocentric use.

The present study reiterates one of the main ideas that we exposed in 1983, in the paper “Din fals rezultă orice” (“From False Follows Anything”), published in the volume Întemeieri raţionale în filosofia ştiinţei (Rational Foundations in the Philosophy of Science) when we referred to the notion of semi-truth, as a third alethic value, placed between „truth” and „falsehood”, thus contributing to the functionality of the trivalent logic. Now we analyze the conceptions of Petre Botezatu, Mario Bunge, Karl R. Popper (...) and Nicholas Rescher, in order to argue that it is important not to identify the epistemological term „probable” (= uncertain) with the semantic term „partial” or „approximate”, when we speak about the concept of truth.

Clausal complements of different kinds of attitude verbs such as believe, doubt, be surprised, wonder, say, and whisper behave differently semantically in a number of respects. For example, they differ in the inference patterns they display. This paper develops a semantic account of clausal complements using partial logic which accounts for such semantic differences on the basis of a uniform meaning of clauses. It focuses on explaining the heterogeneous inference patterns associated with different kinds of attitude verbs, but it (...) contributes also to explaining differences among clausal complements of attitude verbs regarding the possibility of de re reference, anaphora support, presupposition satisfaction, and the distribution of subjunctive in certain languages. Moreover, it gives a new account of factivity. The point of departure of this paper is the general observation that the failure of inferences from attitude reports is relative in that it depends both on the general type of attitude and on the particular instance of the attitude described. Thus, from John is surprised that P and Q one cannot infer John is surprised that P and John is surprised that Q, though this is possible with believe. Conversely, one can infer from John believes that P and John believes that Q, to John believes that P and Q, but only as long as the same belief state of John is involved. In order to capture this dependency of inferences from attitude reports on a particular mental state or act, I propose an account on which clausal complements of attitude verbs (as well as independent sentences) characterize the intentional state or act described by the attitude verb in question, rather than referring to independent propositions. The semantic account of attitude reports of this paper can hence be called an 'event-based account' of clauses. Formally, the denotation of any sentence, both independent and embedded, is construed as a function mapping an intentional state or act to a function from situations (which form the content of the state or act) to truth values..

Wigner famously referred to the `unreasonable effectiveness' of mathematics in its application to science. Using Wigner's own application of group theory to nuclear physics, I hope to indicate that this effectiveness can be seen to be not so unreasonable if attention is paid to the various idealising moves undertaken. The overall framework for analysing this relationship between mathematics and physics is that of da Costa's partial structures programme.

I reply to comments and criticism of my book Roads to Reference by Scott Soames (on the referents of ordinary substance terms and the conventions governing reference fixing for demonstratives, proper names, and color adjectives), Panu Raatikainen (on the exact scope of my critique of descriptivism and on the relation between referential indeterminacy and ‘‘partial reference’’), and Michael Devitt (on the role of referential intentions and anti-descriptivism in the metasemantics of demonstratives).

Solidarity is commonly invoked in the justification of public health care. This is understandable, as calls for and appeals to solidarity are effective in the mobilization of unison action and the willing- ness to incur sacrifices for others. However, the reference to solidarity as a moral notion requires caution, as there is no agreement on the meaning of solidarity. The article argues that the refer- ence to solidarity as a normative notion is relevant to health-related moral claims, but that (...) it does not provide a convincing foundation of claims to universal health care. References to universal soli- darity obliterate an important distinction between those moral demands that are founded on principles like justice, recognition, or humanity, and those demands that stem from partisan rela- tions in communities. While there is no ‘separate essence’ of solidarity that could be referred to in order to argue for the conceptual necessity of solidarity’s partiality, some features may reasonably be stipulated as being essential to solidarity with a view to its systematic function within moral phi- losophy. The normative and motivational force of the ties invoked by solidarity is particularly relevant when basic moral demands are not met, and societies are in need of significant forms of communal relatedness.

The doctrine of eliminative materialism holds that belief-desire psychology is massively referentially disconnected. We claim, however, that it is not at all obvious what it means to be referentially (dis)connected. The two major accounts of reference both lead to serious difficulties for eliminativism: it seems that elimination is either impossible or omnipresent. We explore the idea that reference fixation is a much more local, partial, and context-dependent process than was supposed by the classical accounts. This pragmatic view (...) suggests that elimination is not the prime model for understanding the complex relations between the mind and brain sciences, and that we have little ground for concluding that in general psychological kinds do not exist. We suggest that reference changes are better seen as continuous rather than completely eliminative. (shrink)

This article introduces three arguments that share a single conclusion: that a comprehensive science of language cannot describe relations of semantic reference, i.e. word–world relations. Spelling this out, if there is to be a genuine science of linguistic meaning, then a theory of meaning cannot involve assigning external, real-world, objects to names, nor sets of external objects to predicates, nor truth values to sentences. Most of the article tries to explain and defend this broad conclusion. The article also presents, (...) in a very limited way, a positive alternative to external-referent semantics for expressions. This alternative has two parts: first, that the meanings of words and sentences are mental instructions, not external things; second, that it is people who refer by using words and sentences, and word/sentence meanings play but a partial role in allowing speakers to talk about the world.

This essay asks whether there is a relation between action-serving and meaning-serving intentions. The idea that the intentions involved in meaning and action are nominally designated alike as intentionalities does not guarantee any special logical or conceptual connections between the intentionality of referential thoughts and thought-expressive speech acts with the intentionality of doing. The latter category is typified by overt physical actions in order to communicate by engaging in speech acts, but also includes at the origin of all artistic and (...) symbolic expression such cerebral and linguistic doings as thinking propositional thoughts. There are exactly four possibilities by which meaning and action intentionalities might be related to be systematically investigated. Meaning-serving and action-serving intentionalities, topologically speaking, might exclude one another, partially overlap with one another, or subsume one in the other or the other in the one. The theoretical separation of the two ostensible categories of intendings is criticized, as is their partial overlap, in light of the proposal that thinking and artistic and symbolic expression are activities that favor the inclusion of paradigm meaning-serving intentions as among a larger domain of action-serving intentions. The only remaining alternative is then developed, of including action-serving intentions reductively in meaning-serving intentions, and is defended as offering in an unexpected way the most cogent universal reductive ontology in which the intentionality of doing generally relates to the specific intentionality of referring in thought to the objects of predications, and of its artistic and symbolic expression.

"Partial realism" is a common position in the contemporary philosophy of science literature. It states that the "essential" elements of empirically successful scientific theories accurately represent corresponding features the world. This thesis makes several novel contributions related to this position. Firstly, it offers a new definition of the concept of “empirical success”, representing a principled merger between the use-novelty and unification accounts. Secondly, it provides a comparative critical analysis of various accounts of which elements are "essential" to the success (...) of a theory, including structural realism and the divide et impera strategy. A novel account of essentialness, entitled the “empirically successful sub-theory "account", is defended. Thirdly, it is argued that the realism/anti-realism debate should put to the side metaphysical questions and focus instead on partial realism's commitment to the continuity of science. Because this commitment lacks metaphysical implications, it is referred to as "deflationary realism". Anti-realists cannot reject deflationary realism as a matter of a priori principle; its overall viability can therefore only be assessed by a careful examination of the history of science. Finally, another consequence of partial realism, named "partial rationalism", is defended. Partial rationalism states that, in cases where several competing theories have been suggested, scientists are rational just in case they accept the essential elements of each of the scientific theories on offer. This novel position subverts the existing literature on scientific "revolutions", as it sometimes demands that scientists devise a synthesis between competing scientific theories, instead of "choosing" only one. The philosophical points defended in this thesis are illustrated and supported by case studies from the history of science, including Fresnel’s wave theory of light, the Copernican revolution, the "neo-Darwinian synthesis" in evolutionary biology, the "prion revolution" in molecular biology, the miasma theory of disease, and the chemical revolution.

The widespread assumption among academic philosophers that no truth can be simultaneously necessary and factual, founded on the analytic-synthetic dichotomy, was challenged from outside the profession by Ayn Rand and Leonard Peikoff in the 1960s, and from within the profession by Saul Kripke and Hilary Putnam in the 1970s. Gregory M. Browne's book Necessary Factual Truth represents a long-overdue attempt to synthesize the Rand-Peikoff and Kripke-Putnam approaches into an integrated theory. While Browne's project is partially successful, it gives up one (...) of the chief attractions of these approaches: the ability to preserve continuity of reference across radical theoretical change.

In this paper we recall, improve, and extend several definitions, properties and applications of our previous 2019 research referred to NeutroAlgebras and AntiAlgebras (also called NeutroAlgebraic Structures and respectively AntiAlgebraic Structures). Let <A> be an item (concept, attribute, idea, proposition, theory, etc.). Through the process of neutrosphication, we split the nonempty space we work on into three regions {two opposite ones corresponding to <A> and <antiA>, and one corresponding to neutral (indeterminate) <neutA> (also denoted <neutroA>) between the opposites}, which may (...) or may not be disjoint – depending on the application, but they are exhaustive (their union equals the whole space). A NeutroAlgebra is an algebra which has at least one NeutroOperation or one NeutroAxiom (axiom that is true for some elements, indeterminate for other elements, and false for the other elements). A Partial Algebra is an algebra that has at least one Partial Operation, and all its Axioms are classical (i.e. axioms true for all elements). Through a theorem we prove that NeutroAlgebra is a generalization of Partial Algebra, and we give examples of NeutroAlgebras that are not Partial Algebras. We also introduce the NeutroFunction (and NeutroOperation). (shrink)

Illness and hospitalization are sources of vulnerability; they arguably endow nurses and midwives with the moral obligation to develop caring relationships with patients. Fairness and the equal treatment of patients are central to moral practice; current government publications are giving this political emphasis. This article argues that patient partiality is one factor that may result in insidiously unequal caregiving. Data generated during a qualitative study into professional caring suggest that patient partiality is an accepted part of everyday practice. Factors such (...) as the patient’s personality, nurse-patient familiarity and the perceived level of patients’ understanding and interest in their illness emerged as possible sources of partiality and influence on practitioners’ interactions with patients. The article argues that patient partiality can be managed morally if practitioners develop self-awareness and constantly reflect on the moral integrity of everyday practice. Throughout the article, unless it is stated that specific reference is being made to either nurses or midwives, reference to a nurse or practitioner denotes both. It is also emphasized that no implication is intended that any study participants provided unequal care. Rather, data are utilized solely to generate focused discussion around the concept of patient partiality. (shrink)

What account of evaluative expressions, such as ‘is beautiful’, ‘is generous’ or ‘is good’, should a Fregean adopt? Given Frege’s claim that predicates can have both a sense and a reference in addition to their extension, an interesting range of only partially explored theoretical possibilities opens to Frege and his followers. My intention here is to briefly present these putative possibilities and explore one of them, namely David Wiggins’ claim that evaluative predicates refer to non-natural concepts and have a (...) sense which is sentiment-involving. In order to defend this claim against objections which aim at showing that evaluative concepts do not really exist, I shall suggest that our awareness of evaluative concepts involves affective (or emotive) states.

I introduce an extension of the Lewis-Skyrms signaling game, analysed from a dynamical perspective via simple reinforcement learning. In Lewis’ (Convention, Blackwell, Oxford, 1969) conception of a signaling game, salience is offered as an explanation for how individuals may come to agree upon a linguistic convention. Skyrms (Signals: evolution, learning & information, Oxford University Press, Oxford, 2010a) offers a dynamic explanation of how signaling conventions might arise presupposing no salience whatsoever. The extension of the atomic signaling game examined here—which I (...) will refer to as a salience game—introduces a variable parameter into the atomic signaling game which allows for degrees of salience, thus filling in the continuum between Skyrms’ and Lewis’ models. The model does not presuppose any salience at the outset, but illustrates a process by which accidentally evolved salience is amplified, to the benefit of the players. It is shown that increasing degrees of salience allow populations to avoid sub-optimal pooling equilibria and to coordinate upon conventions more quickly. (shrink)

It has been found that children appreciate the limited substitutability of co-referential terms in opaque contexts a year or two after they pass false belief tasks (e.g. Apperly and Robinson, 1998, 2001, 2003). This paper aims to explain this delay. Three- to six-year-old children were tested with stories where a protagonist was either only partially informed or had a false belief about a particular object. Only a few children had problems predicting the protagonist’s action based on his partial knowledge, (...) when he was only partially informed about a property of the desired object (e.g. he knew that it was a Lego® block, but not that it was a red Lego® block). But many had problems making the correct action prediction when he was only partially informed about dual identities (e.g. he knew it was a dog, but not that it was also an eraser). About as many children made an incorrect action prediction for partial knowledge problems involving dual identity as answered higher-order belief questions incorrectly. In contrast many more children answered first-order false belief questions correctly, as many as correct action predictions when the protagonist was partially informed about a property of an object. The results support the claim that children have a specific problem with dual identity, rather than a broader problem representing partial knowledge. (shrink)

In contrast to Constructivist Views, which construe perceptual cognition as an essentially reconstructive process, this article recommends the Deictic View, which grounds perception in perceptual-demonstrative reference and the use of deictic tracking strategies for acquiring and updating knowledge about individuals. The view raises the problem of how sensory-motor tracking connects to epistemic and integrated forms of tracking. To study the strategies used to solve this problem, we report a study of the ability to track distal individuals when only their (...) directions can be perceived and not their locations. We introduce a new experimental paradigm named the 'Modified Traveling Salesman Problem' (MTSP), which requires subjects to visit n invisible targets in a 2D display once each. Surprisingly, subjects are competent at this task for up to 10 targets. We consider two types of tracking strategies that subjects might use: 'location-based' strategies and 'deictic direction-based' strategies. A number of observations suggest that subjects used the latter, at least for larger numbers of targets. We hypothesize that subjects used perceptual-demonstrative reference and deictic strategies (i) to perform the sensory-motor tracking of directional segments, (ii) to bind the segments with their updated status in the task, and (iii) to perform the epistemic tracking of invisible targets by means of perception-based inferences.

This article proposes an eclectic and holistic model of ethics and ethical thinking. It uses this tripart model to show how partialities can be integrated into impartial moral reasoning. Ethical reasoning is divided into three problem areas or "levels" - cases, frameworks, and ultimate ethical goals. Each level employs its own form of reasoning. For evaluating cases, the author advocates an eclectic application of principles; for evaluating frameworks of principles, the author advocates contractualism; for evaluating ethical theory as a whole, (...) the author advocates a notion of the human good inspired by Aristotelian perfectionism. This article argues that utilitarianism, which is one part of eclectic deliberation, is hampered by the idea that ethical reasoning must be based on a single moral criterion or "master" principle. The article concludes by showing how this eclectic model, supplemented by "mitigated impartialism," provides a systematic method for assessing partialities, with reference to the problem of patriotism in journalism.

Based on existence equations, quasivarieties of heterogeneous partial algebras have the same algebraic description as those of total algebras. Because of the restriction of the valuations to the free variables of a formula — the usual reference to the needed variables e.g. for identities (in order to get useful and manageable results) is essentially replaced here by the use of the logical Craig projections — already varieties of heterogeneous partial algebras behave to some extent rather like quasivarieties (...) than having the properties known from varieties of total homogeneous algebras. It is one of the main aims of this note to make this more explicit. On the other hand we want to list several results known for quasivarieties of heterogeneous partial algebras — and adopt them to the extended signature — after having recalled the language and the main concepts necessary for the understanding of the results.

In the first part of this text, the author explains the arguments against partiality in moral decision-making, as well as the arguments advocating for partiality and indicating to limitations and possible unacceptable consequences of impartial position. The central part of the text concerns the moral status of personal projects and the issue of whet her and how relation ships and close ness between persons are relevant for moral decision-making. The final part discusses the importance of reflection regarding the limits of (...) validity of moral reasons of partiality, while pointing at the crucial importance of nature of relations between people, the context and moral relevance or the significance of case to which moral assessment refers.
