In this paper, we introduce the basics of what we shall call "partial model theory", which is an extension of traditional model theory to partial structures. These are a specific kind of structure developed within the partial structures approach, which is a view constituting the semantic approach of theories. And together with other related semantical concepts, like the concept of quasi-truth, partial structures have been used in contemporary philosophy of science for several purposes. Nonetheless, those uses presuppose certain technical results, (...) or could be improved by resorting to certain technical notions and results, that have not been put forward so far. Thus, in the present work, we intend to introduce part of this particular technical apparatus that is still lacking especially in logic, throughout the development of partial model theory. We begin by extending traditional notions of model theory for partial structures, like the notions of substructure and homomorphism, and by proving some results concerning the notion of quasi-truth. Posteriorly, we show how the content introduced can be used to improve a particular application of partial structures and quasi-truth in the philosophy of science. (shrink)

We argue for asymmetries between positive and negative partiality. Specifically, we defend four claims: i) there are forms of negative partiality that do not have positive counterparts; ii) the directionality of personal relationships has distinct effects on positive and negative partiality; iii) the extent of the interactions within a relationship affects positive and negative partiality differently; and iv) positive and negative partiality have different scope restrictions. We argue that these asymmetries point to a more fundamental (...) moral principle, which we call Morality’s Harmonious Propensity. According to this principle, morality has a propensity toward preserving positive relationships and dissolving negative ones. (shrink)

Implicational tonoid logics and their extensions with abstract Galois properties have been introduced by Yang and Dunn. They introduced matrix semantics for the implicational tonoid logics but did not do for the extensions. Here we provide such semantics for implicational partial gaggle logics as one sort of such extensions. To this end, first we discuss implicational partial gaggle logics in Hilbert-style. We next introduce one kind of matrix semantics based on Lindenbaum– Tarski matrices for the logics and show that those (...) logics are complete with respect to the matrix semantics. Finally, we further introduce a slightly different kind of matrix semantics based on reduced models for the logics and show that those logics are complete with respect to this matrix semantics.

Prospective parents are sometimes partial towards their future children, engaging in what I call ‘pre-parental partiality’. Common sense morality is as permissive of pre-parental partiality as it is of ordinary parental partiality—partiality towards one’s existing children. But I argue that existing justifications for partiality typically establish weaker reasons in support of pre-parental partiality than in support of parental partiality. Thus, either these existing justifications do not fully account for our reasons of parental (...) class='Hi'>partiality, or our reasons to engage in pre-parental partiality are indeed typically weaker than our reasons to engage in parental partiality.

In 'Aboutness' (MIT Press 2014), Yablo argues for the importance of the notions of partial content and of partial truth. This paper argues that those notions are involved in a much greater range of entities than acknowledged by Yablo. The paper also argues that some of those entities involve a notion of partial satisfaction as well as partial existence (and partial validity).

People often fail to comply with the demands of morality. Partial compliance theory takes this noncompliance or its possibility into account in the formulation of moral requirements for people to comply with, or in the evaluation of people’s actions against those requirements. This chapter critically engages with recent work on partial compliance theory. It examines the relationship between noncompliance and injustice, assesses different ways of doing partial compliance theory, sketches the relationship between partial compliance theory and other central methodological debates (...) in moral and political philosophy, and considers whether it is reasonable to issue moral requirements without examining what would happen if everyone did their part.

This paper provides a defence of the account of partial resemblances between properties according to which such resemblances are due to partial identities of constituent properties. It is argued, first of all, that the account is not only required by realists about universals à la Armstrong, but also useful (of course, in an appropriately re-formulated form) for those who prefer a nominalistic ontology for material objects. For this reason, the paper only briefly considers the problem of how to conceive of (...) the structural universals first posited by Armstrong in order to explain partial resemblances, and focuses instead on criticisms that have been levelled against the theory (by Pautz, Eddon, Denkel and Gibb) and that apply regardless of one’s preferred ontological framework. The partial identity account is defended from these objections and, in doing so, a hitherto quite neglected connection—between the debate about partial similarity as partial identity and that concerning ontological finitism versus infinitism—is looked at in some detail.

Partiality is the special concern that we display for ourselves and other people with whom we stand in some special personal relationship. It is a central theme in moral philosophy, both ancient and modern. Questions about the justification of partiality arise in the context of enquiry into several moral topics, including the good life and the role in it of our personal commitments; the demands of impartial morality, equality, and other moral ideals; and commonsense ideas about supererogation. This (...) paper provides an overview of the debate on the ethics of partiality through the lens of the domains of permissible and required partiality. After outlining the conceptual space, I first discuss agent-centred moral options that concern permissions not to do what would be impartially optimal. I then focus on required partiality, which concerns associative duties that go beyond our general duties to others and require us to give special priority to people who are close to us. I discuss some notable features of associative duties and the two main objections that have been raised against them: the Voluntarist and the Distributive objections. I then turn to the justification of partiality, focusing on underivative approaches and reasons-based frameworks. I discuss the reductionism and non-reductionism debate: the question whether partiality is derivative or fundamental. I survey arguments for ‘the big three’, according to which partiality is justified by appeal to the special value of either projects, personal relationships, or individuals. I conclude by discussing four newly emerging areas in the debate: normative transitions of various personal relationships, relationships with AI, epistemic partiality, and negative partiality, which concerns the negative analogue of our positive personal relationships. (shrink)

In moral and political philosophy, topics like the distributive inequities conferred via special partial relationships – family relationships, for example – have been frequently debated. However, the epistemic dimensions of such partiality are seldom discussed in the ethical context, and the topic of partial relationships rarely feature in the realm of social epistemology. My view is that the role of partial relationships is worth exploring to enrich our understanding of epistemic injustice and its transmission. I claim that epistemic features (...) typical of partial relationships make phenomena like epistemic injustice easier to mask, more difficult to identify, and harder to correct. (shrink)

Why do relationships of friendship and love support partiality, but not relationships of hatred or commitments of racism? Where does partiality end and why? I take the intuitive starting point that important cases of partiality are meaningful. I develop a view whereby meaning is understood in terms of transcending self-limitations in order to connect with things of external value. I then show how this view can be used to distinguish central cases of legitimate partiality from cases (...) of illegitimate partiality and how it puts pressure on the traditional way of thinking about partiality.

Virtue theories can plausibly be argued to have important advantages over normative ethical theories which prescribe a strict impartialism in moral judgment, or which neglect people’s special roles and relationships. However, there are clear examples of both virtuous and vicious partiality in people’s moral judgments, and virtue theorists may struggle to adequately distinguish them, much as proponents of other normative ethical theories do. This paper first adapts the “expanding moral circle” concept and some literary examples to illustrate the difficulty (...) of adequately distinguishing virtuous from vicious partiality. Later sections aim to show how an adequate philosophical ethics will be able to both a) attribute virtue (and hence praiseworthiness) to agents whose actions may directly serve only their special interests, roles, or special relationships; and b) attribute vice (and hence censure) where an agent’s attitudes and/or actions mirror known personal biases (for instance, an egoistic attitude) or social biases (for instance, and ethnocentric attitude). This dual ability leaves space for much virtuous partiality, while also reflecting a “risk-aware” approach, recognizing the deleterious consequences of our human penchant for constructing and imbuing moral significance to oftentimes factitious us/them dichotomies.

“Bioconservatives” in the human enhancement debate endorse the conservative claim that we should reject the use of biotechnologies that enhance natural human capacities. However, they often ground their objections to enhancement with contestable claims about human nature that are also in tension with other common tenets of conservatism. We argue that bioconservatives could raise a more plausible objection to enhancement by invoking a strain of conservative thought developed by G.A. Cohen. Although Cohen’s conservatism is not sufficient to fully revive the (...) bioconservative objection, we argue that it can be supplemented by an account of reasonable partiality for humanity in a way that provides further support to the bioconservative position in a manner congruous with broader conservatism. We propose that the idea of partiality to humanity can buttress the bioconservative objection into its strongest possible form. However, we conclude by arguing that, even in this form, the objection cannot do all the work that bioconservatives expect of it. (shrink)

We have to gain from recognizing a relation between epistemic agents and the parts of subject matters that play a role in their cognitive lives. I call this relation “grasping”. Namely, I zone in on one notion of having a partial grasp of a subject matter—that of agents grasping part of the subject matter that they are attending to—and characterize it. I propose that giving up the idealization that we fully grasp the subject matters we attend to allows one to (...) more realistically characterize the epistemic life of agents. To show this, I propose an epistemic logic with partial grasp that has in mind considerations from first-order aboutness theory with the aim of avoiding certain forms of logical omniscience, and which provides an alternative to immanent closure (Yablo Aboutness, Princeton University Press, 2014).

Two doxastically significant demands of friendship have been discussed in recent literature, a demand to be epistemically partial and a demand to take our friends seriously. Though less discussed than epistemic partialism, I suggest that the demand to take our friends seriously is motivated by similar cases and considerations, and can avoid key objections to epistemic partialism that have been raised. I further suggest that it does justice to what we care about in friendship, and thus is to be preferred.

In this paper we consider the theory of predicate logics in which the principle of Bivalence or the principle of Non-Contradiction or both fail. Such logics are partial or paraconsistent or both. We consider sequent calculi for these logics and prove Model Existence. For L4, the most general logic under consideration, we also prove a version of the Craig-Lyndon Interpolation Theorem. The paper shows that many techniques used for classical predicate logic generalise to partial and paraconsistent logics once the right (...) set-up is chosen. Our logic L4 has a semantics that also underlies Belnap’s [4] and is related to the logic of bilattices. L4 is in focus most of the time, but it is also shown how results obtained for L4 can be transferred to several variants. (shrink)

Bernard Molyneux presents some new arguments against descriptive evidentialism about intuitions. Descriptive evidentialism is the thesis that philosophers use intuitions as evidence. Molyneux's arguments are that: the propositions that intuition putatively supports are treated as having a degree and kind of certainty and justification that they could not have got from being intuited; intuitions influence us in ways we cannot explain by supposing we treat them as evidence; and certain strong intuitions that persuade us of their contents are treated as (...) inadmissible in the context of justification. This article presents a partial defence of descriptive evidentialism against these new arguments. (shrink)

In this paper, I make a case for the view that we have special relationship duties (also known as “associative duties”) that are not identical to or derived from our non-associative impartial moral obligations. I call this view “moral partialism”. On the version of moral partialism I defend, only loving relationships can normatively ground special relationship duties. I propose that for two capable adults to have a loving relationship, they must have mutual non-trivial desires to promote each other’s interests or (...) flourishing and to respect each other’s core values. Along the way, I critically ascertain three alternative accounts of what normatively grounds special relationship duties and argue that my proposed view avoids the problems plaguing the alternatives.

Discussion of whether values and norms are neutral or not has mainly appeared in works on the nature of prudential rationality and morality. Little systematic has yet appeared in the up and coming field of the meaning of life. What are the respects in which the value of meaningfulness is neutral or, in contrast, partial, relational, or ‘biased’? In this article, I focus strictly on answering this question. First, I aim to identify the salient, and perhaps exhaustive, respects in which (...) issues of neutrality arise in the contexts of life’s meaning. In addition to providing a taxonomy of the key points of contention, a second aim is to advance reflection about them by considering the most important arguments that have been marshalled in favour of one side or the other, particularly as they appear in recent neutral positions. I conclude that meaning in life is neutral with respect to time but not any other conditions such as agents and patients, with a third aim being to point out that this makes the value of meaning different from the kinds of non/neutrality encountered in some salient conceptions of prudence and morality.

Doxasticism is the thesis that intention is or involves belief in the forthcoming action (Velleman, Harman). Supporters claim that it is only by accepting that thesis that we can explain a wide array of important phenomena, including the special knowledge we have of intentional action, the roles intention plays in facilitating coordination, and the norms of rationality for intention. Others argue that the thesis is subject to counterexample (Davidson, Bratman). Yet some others contend that the thesis can be reformulated in (...) a way that avoids such counterexamples and preserves its explanatory significance (Pears, Setiya). Their suggestion is that we view intention as involving partial –rather than full—belief. I argue that while the move from full to partial doxasticism helps to accommodate such counterexamples, it does so in a way that undermines the ability of the resulting view to explain the coordinating roles of and rationality norms for intention.

Most of us believe that partiality applies in a broad range of relationships. One relationship on which there is much disagreement is co-nationality. Some writers argue that co-national partiality is not justified in certain cases, like killing in war, since killing in defense of co-nationals is intuitively impermissible in other contexts. I argue that this approach overlooks an important structural feature of partiality—namely, that its scope is sometimes restricted. In this essay, I show how some relationships that (...) generate reasons of partiality are restricted in scope—that is, they generate reasons within particular contexts or with respect to particular goods. I then argue that co-national partiality is scope restricted. I then show how this fact helps proponents of co-national partiality overcome the aforementioned objection to its application in cases like war. (shrink)

This paper argues for a new understanding of Strawson’s distinction between personal, impersonal, and self-reactive attitudes. Many Strawsonians take these basic reactive attitude types to be distinguished by two factors. Is it the self or another who is treated with good- or ill-will? And is it the self or another who displays good- or ill-will? On this picture, when someone else wrongs me, my reactive attitude is personal; when someone else wrongs someone else, my reactive attitude is impersonal; and when (...) I wrong someone else, my attitude is self-reactive. Against this account, I argue that the basic reactive attitude types are better distinguished according to whether they express partial or impartial concern. This fits Strawson’s discussion in “Freedom and Resentment”, and it allows us to see an important point that the alternative approach obscures. Namely, while attitudes like resentment, gratitude, shame, and pride can arise as responses to our own treatment and behavior, they can also arise as third-party responses to the treatment and behavior of our family members, romantic partners, and close friends. Similarly, attitudes like moral indignation and disapprobation also have a wider scope than is often acknowledged; they can arise as responses to others’ treatment, but they can also arise as responses to our own treatment when we react impartially to circumstances involving ourselves.

Adam Carter (2022) recently proposed that a successful analysis of knowledge needs to include an autonomy condition. Autonomy, for Carter, requires a lack of a compulsion history. A compulsion history bypasses one’s cognitive competences and results in a belief that is difficult to shed. I argue that Carter’s autonomy condition does not cover partially autonomous beliefs properly. Some belief-forming processes are partially bypassing one’s competences, but not bypassing them completely. I provide a case for partially autonomous belief based on processing (...) fluency effects and argue that partially autonomous beliefs only amount to knowledge in some cases. I finally suggest how to adjust the autonomy condition to capture partially autonomous belief properly. (shrink)

Richard Holton has argued that the traditional account of intentions—which only posits the existence of all-out intentions—is inadequate because it fails to accommodate dual-plan cases; ones in which it is rationally permissible for an agent to adopt two competing plans to bring about the same end. Since the consistency norms governing all-out intentions prohibit the adoption of competing intentions, we can only preserve the idea that the agent in a dual-plan case is not being irrational if we attribute to them (...) a pair of partial intentions. I argue that, contrary to initial appearances, (i) Holton has yet to offer us an actual account of partial intentions, and (ii) that the traditional account of intentions already has the resources necessary to accommodate dual-plan cases.

Martha Nussbaum has provided a sustained critique of Cicero’s De officiis (or On Duties), concerning what she claims is Cicero’s incoherent distinction between duties of justice, which are strict, cosmopolitan, and impartial, and duties of material aid, which are elastic, weighted towards those who are near and dear, and partial. No doubt, from Nussbaum’s cosmopolitan perspective, Cicero’s distinction between justice and beneficence seems problematic and lies at the root of modern moral failures to conceptualize adequately our obligations in situations of (...) famine and global inequality. And yet a careful reading of Cicero’s On Duties shows many duties that appear to be partial. It is hard to believe that Cicero’s discussion of these “partial duties” was a mere oversight or omission on his part. Rather, Cicero seemed to have no problem endorsing what I will call the “partial coherence” of duties in the work—namely, the claim that asserting that duties are exhaustively partial or impartial is a false dichotomy. With the help of conceptual analysis by Richard Kraut, my paper aims to establish and defend Cicero’s “partial coherence” against Nussbaum’s criticisms. (shrink)

Joseph Raz claims that there can be reason to do the impossible; but partial compliance with reason is better than non-compliance and the closer one gets to complying with reason, the better. I propose some exceptions.

This is part one of a two-part paper, in which we develop an axiomatic theory of the relation of partial ground. The main novelty of the paper is the of use of a binary ground predicate rather than an operator to formalize ground. This allows us to connect theories of partial ground with axiomatic theories of truth. In this part of the paper, we develop an axiomatization of the relation of partial ground over the truths of arithmetic and show that (...) the theory is a proof-theoretically conservative extension of the theory PT of positive truth. We construct models for the theory and draw some conclusions for the semantics of conceptualist ground. (shrink)

ABSTRACT Katherine Dormandy argues that there is no partiality in virtuous faith. Partiality biases and leads to noetic entrenchment. In response, I contend there is an important sense in which virtuous faith is partial towards its object. Namely, it disposes one to perceive the object as more trustworthy and to rely on this partialist evidence in forming beliefs, even when the impartialist evidence points in the other direction. There are, after all, situations in which impartialist evidence is apt (...) to mislead or to fail to bring one to the truth. In such cases, faith attunes one to the subject’s true motivations and intentions. Here the partiality of faith constitutes a kind of social acuity or expertise, not a bias. Indeed, to lack faith in such situations—and to give impartialist evidence equal weight with the partial—might constitute a kind of bias against the subject, casting his or her actions in an overly negative light.

In special cases of partial twinning, two heads, each supporting a more-orless normal human mental life, emerge from a single torso. It is often argued that there must be two people in such a case, even if there is only one biological organism. That would pose a problem for ‘animalism’, the view that people are organisms. The paper argues that it is very hard to say what sort of non-organisms the people in such cases would be. Reflection on partial twinning (...) is no more comfortable for those who think we’re not organisms than for those who think we are. We may have to accept that a single person could have two separate mental lives. (shrink)

In their strife for designing a moral system where everyone is given equal consideration, cosmopolitan theorists have merely tolerated partiality as a necessary evil (insofar it means that we give priority to our kin opposite the distant needy). As a result, the cosmopolitan ideal has long departed from our moral psychologies and our social realities. Here I put forward partial cosmopolitanism as an alternative to save that obstacle. Instead of demanding impartial universal action, it requires from us that we (...) are equally responsive in all the relationships we stand in. That goes from the local to the cosmopolitan sphere, since I defend that we are related with strangers as co-members of the global community. Thus, partiality not only is accommodated by cosmopolitanism, but actually supports it: only by having meaningful personal relationships we become able to care for distant strangers. (shrink)

Feminist philosophers have argued that the family, as an institution, falls short of justice and have raised concerns about the effects of the family on women and girls. Three lines of critique have focused on John Rawls’ account of the family in A Theory of Justice and Political Liberalism. First, Rawlsian liberalism fails to provide sufficiently robust protections against sexist non-public associations (including the traditional family). Second, Rawlsian liberalism fails to recognize that families, as a rule, are unfair for women (...) and girls. Third, Rawlsian liberalism gives insufficient attention to the moral development of children within families. In this paper, I defend the place of the family in Rawlsian liberalism against these criticisms. In particular, I argue that family autonomy and family privacy are important for securing a primary good- the development of individuals’ capacity for partiality. (shrink)

Comparing different causes’ importance, and apportioning responsibility between them, requires making good sense of the notion of partial explanation, that is, of degree of explanation. How much is this subjective, how much objective? If the causes in question are probabilistic, how much is the outcome due to them and how much to simple chance? I formulate the notion of degree of causation, or effect size, relating it to influential recent work in the literature on causation. I examine to what extent (...) mainstream social science methods--both quantitative and qualitative--succeed in establishing effect sizes so understood. The answer turns out to be, roughly: only to some extent. Next, the standard understanding of effect size, even though widespread, still has several underappreciated consequences. I detail some of those. Finally, I discuss the separate issue of explanandum-dependence, which is essential to assessing any cause’s explanatory importance and yet which has been comparatively neglected. (shrink)

Firstly I characterize Simple Partial Logic (SPL) as the generalization and extension of a certain two-valued logic. Based on the characterization I present two definitions of validity in SPL. Finally I show that given my characterization these two definitions are more appropriate than other definitions that have been prevalent, since both have some desirable semantic properties that the others lack.

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 article applies the tools of experimental philosophy to the ongoing debate about both the theoretical viability and the practical import of partially aggregative moral theories in distributive ethics. We conduct a series of three experiments (N=383): First, we document the widespread occurrence of the intuitions that motivate this position. Our study then moves beyond establishing the existence of partially aggregative intuitions in two dimensions: First, we extend experimental work in such a way as to ascertain which amongst existing versions (...) of partial aggregation (localised vs. global) chimes more fully with moral common sense. Specifically, we document how, in tie-breaking cases, ‘irrelevant goods’ judgments (Kamm) are just as robust as the original aggregative/non-aggregative pair of judgments that constitute partial aggregation. Second, by pairing laypeople’s moral judgments in standard cases with their intuitions about the limits of permissible self-prioritisation, we investigate whether one prominent explanation of why irrelevant claims may not be aggregated (Voorhoeve’s ‘personal prerogative’ argument) can be said to underpin people’s intuitions about the (ir)relevance relation of claims in conflict cases. We close with a discussion of our findings’ practical and theoretical import and highlight avenues for future research. (shrink)

Typically, fair machine learning research focuses on a single decision maker and assumes that the underlying population is stationary. However, many of the critical domains motivating this work are characterized by competitive marketplaces with many decision makers. Realistically, we might expect only a subset of them to adopt any non-compulsory fairness-conscious policy, a situation that political philosophers call partial compliance. This possibility raises important questions: how does partial compliance and the consequent strategic behavior of decision subjects affect the allocation outcomes? (...) If k% of employers were to voluntarily adopt a fairness-promoting intervention, should we expect k% progress (in aggregate) towards the benefits of universal adoption, or will the dynamics of partial compliance wash out the hoped-for benefits? How might adopting a global (versus local) perspective impact the conclusions of an auditor? In this paper, we propose a simple model of an employment market, leveraging simulation as a tool to explore the impact of both interaction effects and incentive effects on outcomes and auditing metrics. Our key findings are that at equilibrium: (1) partial compliance by k% of employers can result in far less than proportional (k%) progress towards the full compliance outcomes; (2) the gap is more severe when fair employers match global (vs local) statistics; (3) choices of local vs global statistics can paint dramatically different pictures of the performance vis-a-vis fairness desiderata of compliant versus non-compliant employers; (4) partial compliance based on local parity measures can induce extreme segregation. Finally, we discuss implications for auditors and insights concerning the design of regulatory frameworks. (shrink)

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)

This paper uses a partially ordered set of syntactic categories to accommodate optionality and licensing in natural language syntax. A complex but well-studied data set pertaining to the syntax of quantifier scope and negative polarity licensing in Hungarian is used to illustrate the proposal. The presentation is geared towards both linguists and logicians. The paper highlights that the main ideas can be implemented in different grammar formalisms, and discusses in detail an implementation where the partial ordering on categories is given (...) by the derivability relation of a calculus with residuated and Galois-connected unary operators.

In a recent article, Krauss (2017) raises some fundamental questions concerning (i) what the desiderata of a definition of lying are, and (ii) how definitions of lying can account for partial beliefs. This paper aims to provide an adequate answer to both questions. Regarding (i), it shows that there can be a tension between two desiderata for a definition of lying: 'descriptive accuracy' (meeting intuitions about our ordinary concept of lying), and 'moral import' (meeting intuitions about what is wrong with (...) lying), vindicating the primacy of the former desideratum. Regarding (ii), it shows that Krauss' proposed 'worse-off requirement' meets neither of these desiderata, whereas the 'comparative insincerity condition' (Marsili 2014) can meet both. The conclusion is that lies are assertions that the speaker takes to be more likely to be false than true, and their distinctive blameworthiness is a function of the extent to which they violate a sincerity norm.

This article ascertains what philosophical implications can be drawn from the moral idea of personhood dominant in African philosophy. This article aims to go beyond the oft-made submission that this moral idea of personhood is definitive of African moral thought. It does so by advancing discourse with regards to personhood by exploring its relationship with another under-explored idea in African ethics, the idea of partialism. This article ultimately argues that the idea of personhood can be associated with two (related) sorts (...) of partialisms: agent-related and other-centered partialisms. (shrink)

We can often permissibly choose a worse self-interested option over a better altruistic alternative. For example, it is permissible to eat out rather than donate the money to feed five hungry children for a single meal. If we eat out, we do something permissibly partial toward ourselves. If we donate, we go beyond the call of moral duty and do something supererogatory. Such phenomena aren’t easy to explain, and they rule out otherwise promising moral theories. Incommensurability and Ruth Chang’s notion (...) of parity can explain certain small improvement puzzles, but they can’t explain permissible partiality and supererogation. On the other hand, Josh Gert’s distinction between justifying and requiring weight can explain all three phenomena: permissible partiality, supererogation, and the relevant small improvement puzzle. Indeed, this chapter provides a reason to endorse the justifying/requiring weight distinction by showing that it provides the only extant explanation of all three phenomena. (shrink)

Even though it is not very often admitted, partial functions do play a significant role in many practical applications of deduction systems. Kleene has already given a semantic account of partial functions using a three-valued logic decades ago, but there has not been a satisfactory mechanization. Recent years have seen a thorough investigation of the framework of many-valued truth-functional logics. However, strong Kleene logic, where quantification is restricted and therefore not truthfunctional, does not fit the framework directly. We solve this (...) problem by applying recent methods from sorted logics. This paper presents a tableau calculus that combines the proper treatment of partial functions with the efficiency of sorted calculi. (shrink)

The paper starts out by distinguishing two closely related hypotheses about extended cognition. According to the strong hypothesis, there are no intrinsic representations in the brain. This is a version of the extended-mind view defended by Andy Clark and Richard Menary. On the weak hypothesis, there are intrinsic representations in the brain but some types of cognition, knowledge or memory are constituted by particular types of external devices or environmental factors that extend beyond the skull and perhaps beyond the skin. (...) This type of view was defended, for example, by Andy Clark and David Chalmers. After drawing this distinction and clarifying the notions of causal influence and constitution, I defend the second weaker hypothesis with respect to procedural knowledge and knowledge of action and show why this sort of view supports what we might call a ‘situationist-friendly virtue epistemology’.

In her paper, “True Faith: Against Doxastic Partiality about Faith (in God and Religious Communities) and in Defense of Evidentialism,” Katherine Dormandy argues against the view that there is a partiality norm on faith. Dormandy establishes this by showing that partiality views can’t give the right responses to encounters with stubborn counter evidence. Either they (anti-epistemic-partiality views) recommend flouting the evidence altogether in order hold on to positive beliefs about the object of faith or they (epistemic- (...) class='Hi'>partiality views) lower the epistemic standards in objectionable ways to alleviate the epistemic pressure imposed by the counterevidence. However, one cannot have praiseworthy faith when one refuses to really grapple with the evidence against the goodness of the faith’s object. So, partiality norms, far from constituting what makes for great faith, importantly stand in its way. Thus, we should reject any partiality norms on faith. We argue that cases of praiseworthy faith involve dispositions to confront the object of faith when presented with stubborn counter evidence against their goodness. Recognizing this enables us to endorse a partiality norm while avoiding Dormandy’s worries. We argue that dispositions to confront the object of faith presuppose positive beliefs about it, thus vindicating partiality. We further argue that the confrontation makes an epistemic demand of the object of faith: produce high confidence in whether it is still worth having faith in, thus carving out a central role for evidentialist norms.

Many of us give to charities that are close to our hearts rather than those that would use our gifts to do more good, impartially considered. Is such partiality to charities acceptable? I argue that if partiality to particular people is justified, we can go SOME distance toward justifying partiality to particular charities. Even so, partiality to charities is justified in fewer cases than most people seem to believe.

Truthmaker monism is the view that the one and only truthmaker is the world. Despite its unpopularity, this view has recently received an admirable defence by Schaffer :307–324, 2010b). Its main defect, I argue, is that it omits partial truthmakers. If we omit partial truthmakers, we lose the intimate connection between a truth and its truthmaker. I further argue that the notion of a minimal truthmaker should be the key notion that plays the role of constraining ontology and that truthmaker (...) monism is not necessary for an appropriate solution to the problem of finding truthmakers for negative truths. I conclude that we should reject truthmaker monism once and for all. (shrink)

This is part two of a two-part paper in which we develop an axiomatic theory of the relation of partial ground. The main novelty of the paper is the of use of a binary ground predicate rather than an operator to formalize ground. In this part of the paper, we extend the base theory of the first part of the paper with hierarchically typed truth-predicates and principles about the interaction of partial ground and truth. We show that our theory is (...) a proof-theoretically conservative extension of the ramified theory of positive truth up to. (shrink)
