Kant divides moral duties into duties of virtue and duties of justice. Duties of virtue are imperfect duties, the fulfillment of which is left to agent discretion and so cannot be externally demanded of one. Duties of justice, while perfect, seem to be restricted to negative duties (of nondeception and noncoercion). It may seem then that Kant's moral philosophy cannot meet the demands of global justice. I argue, however, that Kantian justice when applied to the social and historical realities of (...) the world can generate positive duties to promote and provide for the well being of others.

In bilateral logic formulas are signed by + and –, indicating the speech acts assertion and denial. I argue that making an assumption is also speech act. Speech acts cannot be embedded within other speech acts. Hence we cannot make sense of the notion of making an assumption in bilateral logic. Attempts to solve this problem are considered and rejected.

A number of philosophers have recently proposed several alleged cases of “knowledge from falsehood,” i.e., cases of inferential knowledge epistemised by an inference with a false crucial premise. This paper examines such cases and argues against interpreting them as cases of knowledge from falsehood. Specifically, I argue that the inferences in play in such cases are in no position to epistemise their conclusions.

This chapter examines two basic philosophical challenges for the idea of reparations for past injustices (using colonialism as the focal point). The first challenge is that requiring people today to make reparations for an injustice they themselves did not commit is unfair. The second is that if reparative claims are invoked because of lingering injustices, then recalling the past is in fact normatively redundant if lingering present injustices can be handled by forward-looking principles. In response to the first challenge, I (...) argue that the unfairness worry is deflected if we adopt a collectivist-model of responsibility, ie, one that holds states instead of individuals to be the responsible actor. Against the redundancy objection, I suggest that reparative arguments can supplement and reinforce forward-looking distributive principles. (shrink)

Debates on humanitarian intervention have focused on the permissibility question. In this paper, I ask whether intervention can be a moral duty, and if it is a moral duty, how this duty is to be distributed and assigned. With respect to the first question, I contemplate whether an intervention that has met the "permissibility" condition is also for this reason necessary and obligatory. If so, the gap between permission and obligation closes in the case of humanitarian intervention. On the second (...) question, I propose 'institutionalizing" the duty to intervene. In this way, an otherwise imperfect obligation to intervene can be made "perfect" and specific to some agent. (shrink)

This paper discusses proof-theoretic semantics, the project of specifying the meanings of the logical constants in terms of rules of inference governing them. I concentrate on Michael Dummett’s and Dag Prawitz’ philosophical motivations and give precise characterisations of the crucial notions of harmony and stability, placed in the context of proving normalisation results in systems of natural deduction. I point out a problem for defining the meaning of negation in this framework and prospects for an account of the meanings of (...) modal operators in terms of rules of inference. (shrink)

This paper proves normalisation theorems for intuitionist and classical negative free logic, without and with the $\invertediota$ operator for definite descriptions. Rules specific to free logic give rise to new kinds of maximal formulas additional to those familiar from standard intuitionist and classical logic. When $\invertediota$ is added it must be ensured that reduction procedures involving replacements of parameters by terms do not introduce new maximal formulas of higher degree than the ones removed. The problem is solved by a rule (...) that permits restricting these terms in the rules for $\forall$, $\exists$ and $\invertediota$ to parameters or constants. A restricted subformula property for deductions in systems without $\invertediota$ is considered. It is improved upon by an alternative formalisation of free logic building on an idea of Ja\'skowski's. In the classical system the rules for $\invertediota$ require treatment known from normalisation for classical logic with $\lor$ or $\exists$. The philosophical significance of the results is also indicated. (shrink)

This paper considers a formalisation of classical logic using general introduction rules and general elimination rules. It proposes a definition of ‘maximal formula’, ‘segment’ and ‘maximal segment’ suitable to the system, and gives reduction procedures for them. It is then shown that deductions in the system convert into normal form, i.e. deductions that contain neither maximal formulas nor maximal segments, and that deductions in normal form satisfy the subformula property. Tarski’s Rule is treated as a general introduction rule for implication. (...) The general introduction rule for negation has a similar form. Maximal formulas with implication or negation as main operator require reduction procedures of a more intricate kind not present in normalisation for intuitionist logic. (shrink)

To resolve the lottery paradox, the “no-justification account” proposes that one is not justified in believing that one's lottery ticket is a loser. The no-justification account commits to what I call “the Harman-style skepticism”. In reply, proponents of the no-justification account typically downplay the Harman-style skepticism. In this paper, I argue that the no-justification reply to the Harman-style skepticism is untenable. Moreover, I argue that the no-justification account is epistemically ad hoc. My arguments are based on a rather surprising finding (...) that the no-justification account implies that people living in Taiwan typically suffer from the Harman-style skepticism. (shrink)

ABSTRACTEvaluative aesthetic discourse communicates that the speaker has had first-hand experience of what is talked about. If you call a book bewitching, it will be assumed that you have read the book. If you say that a building is beautiful, it will be assumed that you have had some visual experience with it. According to an influential view, this is because knowledge is a norm for assertion, and aesthetic knowledge requires first-hand experience. This paper criticizes this view and argues for (...) an alternative view, according to which aesthetic discourse expresses affective states of mind, analogously to how assertions express beliefs. It is because these affective states require first-hand experience that aesthetic discourse communicates that such acquaintance is at hand. The paper furthermore argues that the lack of an experience requirement for aesthetic belief ascriptions constitutes a problem for the kind of expressivist who claims that evaluative belief states are covert non-cognitive states.

Ian Rumfitt has proposed systems of bilateral logic for primitive speech acts of assertion and denial, with the purpose of ‘exploring the possibility of specifying the classically intended senses for the connectives in terms of their deductive use’ : 810f). Rumfitt formalises two systems of bilateral logic and gives two arguments for their classical nature. I assess both arguments and conclude that only one system satisfies the meaning-theoretical requirements Rumfitt imposes in his arguments. I then formalise an intuitionist system of (...) bilateral logic which also meets those requirements. Thus Rumfitt cannot claim that only classical bilateral rules of inference succeed in imparting a coherent sense onto the connectives. My system can be extended to classical logic by adding the intuitionistically unacceptable half of a structural rule Rumfitt uses to codify the relation between assertion and denial. Thus there is a clear sense in which, in the bilateral framework, the difference between classicism and intuitionism is not one of the rules of inference governing negation, but rather one of the relation between assertion and denial.

This paper formulates a bilateral account of harmony that is an alternative to one proposed by Francez. It builds on an account of harmony for unilateral logic proposed by Kürbis and the observation that reading the rules for the connectives of bilateral logic bottom up gives the grounds and consequences of formulas with the opposite speech act. I formulate a process I call 'inversion' which allows the determination of assertive elimination rules from assertive introduction rules, and rejective elimination rules from (...) rejective introduction rules, and conversely. It corresponds to Francez's notion of vertical harmony. I also formulate a process I call 'conversion', which allows the determination of rejective introduction rules from assertive elimination rules and conversely, and the determination of assertive introduction rules from rejective elimination rules and conversely. It corresponds to Francez's notion of horizontal harmony. The account has a number of features that distinguish it from Francez's. (shrink)

Luck egalitarianism provides one powerful way of defending global egalitarianism. The basic luck egalitarian idea that persons ought not to be disadvantaged compared to others on account of his or her bad luck seems to extend naturally to the global arena, where random factors such as persons’ place of birth and the natural distribution of the world’s resources do affect differentially their life chances. Yet luck egalitarianism as an ideal, as well as its global application, has come under severe criticisms (...) in recent debate. My aim in this article is to restore plausibility to the luck egalitarian idea, and to suggest how it could then provide a plausible grounding for global egalitarianism. To do this, I will propose a more modest but also more defensible conception of luck egalitarianism that can also strengthen the case for global distributive justice. (shrink)

This paper presents rules of inference for a binary quantifier I for the formalisation of sentences containing definite descriptions within intuitionist positive free logic. I binds one variable and forms a formula from two formulas. Ix[F, G] means ‘The F is G’. The system is shown to have desirable proof-theoretic properties: it is proved that deductions in it can be brought into normal form. The discussion is rounded up by comparisons between the approach to the formalisation of definite descriptions recommended (...) here and the more usual approach that uses a term-forming operator ι, where ιxF means ‘the F’.

In "Rethinking Sadomasochism," Patrick Hopkins challenges the "radical" feminist claim that sadomasochism is incompatible with feminism. He does so by appeal to the notion of "simulation." I argue that Hopkins's conclusions are generally right, but they cannot be inferred from his "simulation" argument. I replace Hopkins's "simulation" with Kendall Walton's more sophisticated theory of "make-believe." I use this theory to better argue that privately conducted sadomasochism is compatible with feminism.

It is widely held within contemporary metaethics that there is a lack of linguistic support for evaluative expressivism. On the contrary, it seems that the predictions that expressivists make about evaluative discourse are not borne out. An instance of this is the so-called problem of missing Moorean infelicity. Expressivists maintain that evaluative statements express non-cognitive states of mind in a similar manner to how ordinary descriptive language expresses beliefs. Conjoining an ordinary assertion that p with the denial of being in (...) the corresponding belief state famously gives rise to Moorean infelicity:?? It’s raining but I don’t believe that it’s raining. If expressivists are right, then conjoining evaluative statements with the denial of being in the relevant non-cognitive state of mind should give rise to similar infelicity. However, as several theorists have pointed out, this does not seem to be the case. Statements like the following are not infelicitous: Murder is wrong but I don’t disapprove of it. In this paper, I argue that evaluative statements express the kind of states that are attributed by ‘find’-constructions in English and that these states are non-cognitive in nature. This addresses the problem of missing Moorean infelicity and, more generally, goes to show that there are linguistic facts which support expressivism about evaluative discourse. (shrink)

Several authors have recently argued against intellectualism, the view that one’s epistemic position with respect to p depends exclusively on one’s truth-relevant factors with respect to p. In this paper, I first examine two prominent arguments for the anti-intellectualist position and find both of them wanting. More precisely, I argue that these arguments, by themselves, are underdetermined between intellectualism and anti-intellectualism. I then manifest the intuitive plausibility of intellectualism by examining the ordinary conversational pattern of challenging a claim.

I outline what I call a relational account of toleration. This relational account helps explain the apparent paradox of toleration in that it involves two competing moral stances, of acceptance and disapproval, towards the tolerated. It also helps clarify the way toleration is a normative ideal, and not a position one is forced into out of the practical need to accommodate or accept. Specifically, toleration is recommended out of respect for that which the tolerant agent also disapproves of. This combination (...) of respect entangled with disapproval results from two different evaluative perspectives of the tolerant agent. The relational account explains how an agent can hold these competing evaluative perspectives. I also discuss the proper scope of state toleration under this relational account. (shrink)

Two classes of arguments are often deployed by the anti-global egalitarians against attempts to universalize the demands of distributive equality. One are arguments attempting to show that global egalitarians have misconstrued the reasons for why equality matters domestically, and hence have wrongly extended these reasons to the global arena. These arguments hold that the boundary of distributive justice is effectively coextensive with the boundaries of state. The other are arguments that attempt to show that membership in political societies generates special (...) duties among members that may outweigh the demands of global egalitarianism. These arguments appeal to the ethical significance of state boundaries and membership. In my defense of global egalitarianism, I reject both the attempts to limit the boundary of justice and the attempts to give state boundaries special moral significance and priority. In particular, I will argue that the boundary of justice cannot coincide with the boundaries of states when the justice of the boundaries is at issue. (shrink)

In this paper, I'll present a general way of "reading off" introduction/elimination rules from elimination/introduction rules, and define notions of harmony and stability on the basis of it.

This is a commentary on MM McCabe's "First Chop your logos... Socrates and the sophists on language, logic, and development". In her paper MM analyses Plato's Euthydemos, in which Plato tackles the problem of falsity in a way that takes into account the speaker and complements the Sophist's discussion of what is said. The dialogue looks as if it is merely a demonstration of the silly consequences of eristic combat. And so it is. But a main point of MM's paper (...) is that there is serious philosophy in the Euthydemos, too. MM argues that to counter the sophist brothers Euthydemos and Dionysodoros, Socrates points out that that there are different aspects to the verb 'to say' that run in parallel to the different aspects of the very 'to learn'. So just as there is continuity rather than ambiguity between 'to learn' and 'to understand', so there is continuity between the different aspects of saying. Thus Socrates puts forward a teleological account of both learning and meaning. Following up on some of MM's thoughts, I argue that the sophists subscribe, despite appearance, to a theory of meaning that respects serious and widely accepted philosophical theses on meaning. -/- Forthcoming in the Australasian Philosophical Review.

Bilateralists hold that the meanings of the connectives are determined by rules of inference for their use in deductive reasoning with asserted and denied formulas. This paper presents two bilateral connectives comparable to Prior's tonk, for which, unlike for tonk, there are reduction steps for the removal of maximal formulas arising from introducing and eliminating formulas with those connectives as main operators. Adding either of them to bilateral classical logic results in an incoherent system. One way around this problem is (...) to count formulas as maximal that are the conclusion of reductio and major premise of an elimination rule and to require their removability from deductions. The main part of the paper consists in a proof of a normalisation theorem for bilateral logic. The closing sections address philosophical concerns whether the proof provides a satisfactory solution to the problem at hand and confronts bilateralists with the dilemma that a bilateral notion of stability sits uneasily with the core bilateral thesis.

Rumfitt has given two arguments that in unilateralist verificationist theories of meaning, truth collapses into correct assertibility. In the present paper I give similar arguments that show that in unilateral falsificationist theories of meaning, falsehood collapses into correct deniability. According to bilateralism, meanings are determined by assertion and denial conditions, so the question arises whether it succumbs to similar arguments. I show that this is not the case. The final section considers the question whether a principle central to Rumfitt's first (...) argument, ‘It is assertible that if and only if it is assertible that it is assertible that ’, is one that bilateralists can reject, and concludes that they cannot. It follows that the logic of assertibility and deniability, according to a result by Williamson, is the little known modal logic K4 studied by Sobociński. The paper ends with a plaidoyer for bilateralists to adopt this logic. (shrink)

The outcomes of sports and competitive games excite intense emotions in many people, even when those same people acknowledge that those outcomes are of trifling importance. I call this incongruity between the judged importance of the outcome and the intense reactions it provokes the Puzzle of Sport. The puzzle can be usefully compared to another puzzle in aesthetics: the Paradox of Fiction, which asks how it is we become emotionally caught up with events and characters we know to be unreal. (...) In this article, I examine the prospects of understanding our engagement with competitive games on the model of our engagement with works of fiction, thus enabling analogous explanations for both puzzles. I show that there are significant problems with such an approach and offer an alternative, mobilizing ideas from David Velleman and Thomas Nagel, that appeals to the volatility of our motivational attitudes.

This paper draws attention to a proof of the necessity of identity given by Arthur Prior. In its simplicity, it is comparable to a proof of Quine's, popularised by Kripke, but it is slightly different. Prior's Polish notation is transcribed into a more familiar idiom. Prior's proof is followed by a proof of the necessity of difference, possibly the first such proof in the literature, which is also repeated here and transcribed. The paper concludes with a brief discussion of Prior's (...) views on identity and difference over time. (shrink)

Within contemporary metaethics, it is widely held that there is a “presumption of realism” in moral thought and discourse. Anti-realist views, like error theory and expressivism, may have certain theoretical considerations speaking in their favor, but our pretheoretical stance with respect to morality clearly favors objectivist metaethical views. This article argues against this widely held view. It does so by drawing from recent discussions about so-called “subjective attitude verbs” in linguistics and philosophy of language. Unlike pretheoretically objective predicates (e.g., “is (...) made of wood”, “is 185 cm tall”), moral predicates embed felicitously under subjective attitude verbs like the English “find”. Moreover, it is argued that the widespread notion that moral discourse bears all the marks of fact-stating discourse is rooted in a blinkered focus on examples from English. Cross-linguistic considerations suggest that subjective attitude verbs are actually the default terms by which we ascribe moral views to people. Impressions to the contrary in English have to do with some unfortunate quirks of the term “think”. (shrink)

Reasons evidentialism is the view that normative reasons can be analyzed in terms of evidence about oughts (i.e., propositions concerning whether or not S ought to phi). In this paper, I defend a new reason-evidentialist account according to which normative reasons are evidence against propositions of the form S ought not to phi. The arguments for my view have two strands. First of all, I argue that my view can account for three difficulty cases, cases where (i) a fact is (...) both a reason for S to phi and a reason for S not to phi, (ii) a fact is both evidence for the proposition that S ought to phi and evidence for the proposition that S ought not to phi, and (iii) the subject is genuinely torn, as far as reasons are concerned, between phi-ing and not phi-ing. Second, I argue that my view can account for what a reason against S phi-ing is. (shrink)

This review essay on John Rawls’s The Law of Peoples focuses on two of its more contentious claims. The first is that international economic justice is secured by a principle of assistance and that a principle of distributive justice will in fact have “unacceptable” results. The other is that certain non-liberal societies, or peoples, fall within the limits of international toleration. The essay evaluates and critiques these claims from a liberal cosmopolitan perspective.

It is widely accepted that our initial intuitions regarding knowledge attributions in stakes-shifting cases (e.g., Cohen’s Airport) are best explained by standards variantism, the view that the standards for knowledge may vary with contexts in an epistemically interesting way. Against standards variantism, I argue that no prominent account of the standards for knowledge can explain our intuitions regarding stakes-shifting cases. I argue that the only way to preserve our initial intuitions regarding such cases is to endorse position variantism, the view (...) that one’s epistemic position may vary with contexts in an epistemically interesting way. Some had argued that epistemic position is incompatible with intellectualism. In reply, I point out that position variantism and intellectualism are compatible, if one’s truth-relevant factors with respect to p can vary with contexts in an epistemically interesting way.

The fundamental assumption of Dummett’s and Prawitz’ proof-theoretic justification of deduction is that ‘if we have a valid argument for a complex statement, we can construct a valid argument for it which finishes with an application of one of the introduction rules governing its principal operator’. I argue that the assumption is flawed in this general version, but should be restricted, not to apply to arguments in general, but only to proofs. I also argue that Dummett’s and Prawitz’ project of (...) providing a logical basis for metaphysics only relies on the restricted assumption. (shrink)

This paper studies a formalisation of intuitionistic logic by Negri and von Plato which has general introduction and elimination rules. The philosophical importance of the system is expounded. Definitions of ‘maximal formula’, ‘segment’ and ‘maximal segment’ suitable to the system are formulated and corresponding reduction procedures for maximal formulas and permutative reduction procedures for maximal segments given. Alternatives to the main method used are also considered. It is shown that deductions in the system convert into normal form and that deductions (...) in normal form have the subformula property.

This paper presents a way of formalising definite descriptions with a binary quantifier ι, where ιx[F, G] is read as ‘The F is G’. Introduction and elimination rules for ι in a system of intuitionist negative free logic are formulated. Procedures for removing maximal formulas of the form ιx[F, G] are given, and it is shown that deductions in the system can be brought into normal form.

This brief note corrects an error in one of the reduction steps in my paper 'Normalisation for Bilateral Classical Logic with some Philosophical Remarks' published in the Journal of Applied Logics 8/2 (2021): 531-556.

Sentences containing definite descriptions, expressions of the form ‘The F’, can be formalised using a binary quantifier ι that forms a formula out of two predicates, where ιx[F, G] is read as ‘The F is G’. This is an innovation over the usual formalisation of definite descriptions with a term forming operator. The present paper compares the two approaches. After a brief overview of the system INFι of intuitionist negative free logic extended by such a quantifier, which was presented in (...) (Kürbis 2019), INFι is first compared to a system of Tennant’s and an axiomatic treatment of a term forming ι operator within intuitionist negative free logic. Both systems are shown to be equivalent to the subsystem of INFι in which the G of ιx[F, G] is restricted to identity. INFι is then compared to an intuitionist version of a system of Lambert’s which in addition to the term forming operator has an operator for predicate abstraction for indicating scope distinctions. The two systems will be shown to be equivalent through a translation between their respective languages. Advantages of the present approach over the alternatives are indicated in the discussion.

How should liberal societies respond to nonliberal ones? In this paper I examine John Rawls’s conception of international toleration against what is sometimes called a cosmopolitan one. Rawls holds that a just international order should recognize certain nonliberal societies, to which he refers as decent peoples, as equal members in good standing in a just society of peoples. It would be a violation of liberalism’s own principle of toleration to deny the international legitimacy of decent peoples who, among other things, (...) affirm human rights and accept peaceful coexistence with other societies. According to the cosmopolitan idea of international toleration, on the contrary, only societies that are liberal in character meet the criteria for toleration. I suggest that, against the Rawlsian conception of international toleration, the cosmopolitan idea is more consistent with the fundamentals of liberal political morality. I then clarify the ways in which cosmopolitan toleration is not worryingly interventionist even as it is not altogether toothless; and I end with some reflections on why cosmopolitism is not morally imperialistic.

Molnar argues that the problem of truthmakers for negative truths arises because we tend to accept four metaphysical principles that entail that all negative truths have positive truthmakers. This conclusion, however, already follows from only three of Molnar´s metaphysical principles. One purpose of this note is to set the record straight. I provide an alternative reading of two of Molnar´s principles on which they are all needed to derive the desired conclusion. Furthermore, according to Molnar, the four principles may be (...) inconsistent. By themselves, however, they are not. The other purpose of this note is to propose some plausible further principles that, when added to the four metaphysical theses, entail a contradiction. (shrink)

Bilateralists, who accept that there are two primitive speech acts, assertion and denial, can offer an attractive definition of consequence: Y follows from X if and only if it is incoherent to assert all formulas X and to deny all formulas Y. The present paper argues that this definition has consequences many will find problematic, amongst them that truth coincides with assertibility. Philosophers who reject these consequences should therefore reject this definition of consequence.

A well-known theory about under which circumstances a statement is true in a fiction is The Reality Principle, which originate in the work of David Lewis: (RP) Where p1... pn are the primary fictional truths of a fiction F , it is true in F that q iff the following holds: were p1 ... pn the case, q would have been the case (Walton 1990: 44). RP has been subjected to a number of counterexamples, up to a point where, in (...) the words of Stacie Friend “it is widely recognized that the Reality Principle […] cannot be a universal inference rule for implied story-truths” (Friend 2017: 33). This chapter argues that the strength of these counterexamples is widely overestimated, and that they do not, on closer scrutiny, constitute reasons for rejecting RP. (shrink)

Some cases show that counterfactual conditionals (‘counterfactuals’ for short) are inherently ambiguous, equivocating between forward-tracking and backtracking counterfactu- als. Elsewhere, I have proposed a causal modeling semantics, which takes this phenomenon to be generated by two kinds of causal manipulations. (Lee 2015; Lee 2016) In an important paper (Hiddleston 2005), Eric Hiddleston offers a different causal modeling semantics, which he claims to be able to explain away the inherent ambiguity of counterfactuals. In this paper, I discuss these two semantic treatments (...) and argue that my (bifurcated) semantics is theoretically more promising than Hiddleston’s (unified) semantics. (shrink)

Hossack's 'The Metaphysics of Knowledge' develops a theory of facts, entities in which universals are combined with universals or particulars, as the foundation of his metaphysics. While Hossack argues at length that there must be negative facts, facts in which the universal 'negation' is combined with universals or particulars, his conclusion that there are also general facts, facts in which the universal 'generality' is combined with universals, is reached rather more swiftly. In this paper I present Hossack with three arguments (...) for his conclusion. They all draw, as does Hossack's theory of facts, on views Russell expressed in various writings. Two arguments are based on Russell's explanation of universals as aspects of resemblance; the third on Russell's observation that general propositions do not follow logically from exclusively particular premises. Comparison with other metaphysics of generality show them to be wanting and Russell's and Hossack's accounts superior. (shrink)

The problem of negative truth is the problem of how, if everything in the world is positive, we can speak truly about the world using negative propositions. A prominent solution is to explain negation in terms of a primitive notion of metaphysical incompatibility. I argue that if this account is correct, then minimal logic is the correct logic. The negation of a proposition A is characterised as the minimal incompatible of A composed of it and the logical constant ¬. A (...) rule based account of the meanings of logical constants that appeals to the notion of incompatibility in the introduction rule for negation ensures the existence and uniqueness of the negation of every proposition. But it endows the negation operator with no more formal properties than those it has in minimal logic. (shrink)

Recent literature has seen a surging interest in the modal principle involved in the Gettier-style thought experiments. According to the necessitation thesis, the modal principle underlying the Gettier-style thought experiments takes the form of a principle of necessitation. It is widely agreed that the necessitation thesis is seriously threatened by the problem of deviant realizations. Based on the Gricean pragmatic theory of communication, I defend the necessitation thesis against the problem of deviant realizations. The present account bears some significant similarities (...) to Pierre Saint-Germier’s account. After comparing and contrasting these two accounts, I argue that the differences between them actually speak in favor of the present account over Saint-Germier’s one. (shrink)

The stakes-shifting cases suggest that pragmatic factors such as stakes play an important role in determining our intuitive judgments of whether or not S knows that p. This seems to be in conflict with intellectualism, according to which pragmatic factors in general should not be taken into account, when considering whether or not S knows that p. This paper develops a theory of judgments of knowledge status that reconciles intellectualism with our intuitive judgments regarding the stakes-shifting cases. I argue that (...) pragmatic factors affect only our epistemic perspectives, i.e., the ways in which we evaluate S’s epistemic position. Therefore, pragmatic factors only have an indirect impact on our judgments of knowledge status. (shrink)

In this paper, I defend the thesis that knowledge is the norm of assertion. I first examine three prominent “counterexamples”: false assertion, selfless assertion, and assertion based on mere justified true belief. I argue that they all fail to square well with our ordinary intuitions. However, the contemporary debate over the norm of assertion depends heavily on the method of counterexamples, whose crux is to prompt our intuitions regarding the appropriateness (or inappropriateness) of a certain kind of assertions. This method (...) has its limits as sometimes the debate simply boils down to a clash of intuitions. I think we can do better. In the second part of the paper, I construct a positive argument for the knowledge norm, showing that the knowledge norm can be derived from the general account of the conversational role of assertion. I argue that in order for assertion to play the role it plays in conversation, the knowledge norm must hold. (shrink)

Thought experiments that concoct bizarre possible world modalities are standard fare in debates on personal identity. Appealing to intuitions raised by such evocations is often taken to settle differences between conflicting theoretical views that, albeit, have practical implications for ethical controversies of personal identity in health care. Employing thought experiments that way is inadequate, I argue, since personhood is intrinsically linked to constraining facts about the actual world. I defend a moderate modal skepticism according to which intuiting across conceptually incongruent (...) worlds constitutes ‘invalid intuitioninferences’—i.e., carrying over intuitions gathered from facts about possible worlds that are at odds with facts about the actual world, for the purpose of making claims about real-life persons and their identity, leads to conceptual incongruences. Such a methodological fallout precludes accurate, informative judgments about personal identity in the actual world, calling into question the adequacy of thought experimental considerations for potential real world applications in medical ethics.

In 2009, a law was passed in the Danish parliament, according to which judges cannot wear religious symbols in courts of law. First, I trace the development of this legislation from resistance to Muslim religious practices on the nationalist right to ideas in mainstream Danish politics about secularism and state neutrality – a process I refer to as ‘liberalization’. Second, I consider the plausibility of such liberal justifications for restrictions on religious symbols in the public sphere and, in particular, for (...) the ban on the wearing of religious symbols by judges. I argue that such justifications are flawed and so are not plausible corollaries of anti-Islamic justifications originating on the nationalist right. (shrink)
