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.

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.

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)

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.

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)

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)

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)

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)

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 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)

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)

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. (shrink)

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)

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.

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.

Throughout Alexandre Herculano’s historical oeuvre claims of impartiality are mingled with the partiality of the beliefs, ideals, and interests that give shape to the author’s point of view. One can trace in it both the commitment to the disinterested search for truth and the pragmatic intention to remodel the relations of Portuguese society with its past and with the effects of this past on the present. This text revisits Herculano’s major historical writings with the aim of understanding how it is (...) possible for historical texts to be or claim to be at the same time true and useful, objective and engaged, impartial and partial. I intend to show that those oppositions not necessarily entail paralyzing contradictions, and that good historians such as Herculano are usually capable of drawing from them a great amount of intellectual energy. Focusing on the tension between impartiality and partiality, and supported by close readings and contextual analyses, I will try to demonstrate that such tension configures itself in at least two different modes, which in turn depend on the positive or negative significance the studied past turns out to have for the person who studies it.

Many have begun to despair that climate justice will prevail even in a minimal form. The affective dimensions of such despair, we suggest, threaten to make climate action appear too demanding. Thus, despair constitutes a moral challenge to individual climate action that has not yet received adequate attention. In response, we defend a duty to act in hope for a more just (climate) future. However, as we see it, this duty falls differentially upon the shoulders of more and less advantaged (...) agents in society. From arguments by Black thinkers like Derrick Bell, we draw a set of distinctions between two types of hope: one for ideal justice, and one for more modest change; and between two types of hopeful actions, those undertaken through formal political channels and those we call 'extra-political' actions; and between two sites of differential moral burdens, those of the privileged and those of the oppressed. Ours is a case for facing even bleak realities, demanding otherwise, and acting in hope to achieve a better future. (shrink)

The computational paradigm, which has dominated psychology and artificial intelligence since the cognitive revolution, has been a source of intense debate. Recently, several cognitive scientists have argued against this paradigm, not by objecting to computation, but rather by objecting to the notion of representation. Our analysis of these objections reveals that it is not the notion of representation per se that is causing the problem, but rather specific properties of representations as they are used in various psychological theories. Our analysis (...) suggests that all theorists accept the idea that cognitive processing involves internal information-carrying states that mediate cognitive processing. These mediating states are a superordinate category of representations. We discuss five properties that can be added to mediating states and examine their importance in various cognitive models. Finally, three methodological lessons are drawn from our analysis and discussion. (shrink)

Dilation occurs when an interval probability estimate of some event E is properly included in the interval probability estimate of E conditional on every event F of some partition, which means that one’s initial estimate of E becomes less precise no matter how an experiment turns out. Critics maintain that dilation is a pathological feature of imprecise probability models, while others have thought the problem is with Bayesian updating. However, two points are often overlooked: (1) knowing that E is stochastically (...) independent of F (for all F in a partition of the underlying state space) is sufficient to avoid dilation, but (2) stochastic independence is not the only independence concept at play within imprecise probability models. In this paper we give a simple characterization of dilation formulated in terms of deviation from stochastic independence, propose a measure of dilation, and distinguish between proper and improper dilation. Through this we revisit the most sensational examples of dilation, which play up independence between dilator and dilatee, and find the sensationalism undermined by either fallacious reasoning with imprecise probabilities or improperly constructed imprecise probability models.

There is a remarkable trend in contemporary environmentalism that emphasizes ‘accepting responsibility’ for the natural world in contrast to outdated preservationist thinking that shirks such responsibility. This approach is often explained and justified by reference to the anthropocene: this fundamentally new epoch—defined by human domination—requires active human intervention to avert planetary catastrophe. However, in this paper, I suggest this rhetoric encourages a flight from history. This often jubilant, sometimes anxious, yearning for unprecedented human innovation and—ultimately—control in our new millennia mirrors (...) the Futurist movement that took off near the beginning of the last century. Despite the significant differences in the details of how academics have defended this twenty-first-century environmental outlook, they all represent the true flight from history; they too quickly jettison the ideas of historical environmentalists and so misunderstand the environmental values at the heart of preservation that are more salient than ever.

A scholar of Hellenistic and Prussian history, Droysen developed a historical theory that at the time was unprecedented in range and depth, and which remains to the present day a valuable key for understanding history as both an idea and a professional practice. Arthur Alfaix Assis interprets Droysen’s theoretical project as an attempt to redefine the function of historiography within the context of a rising criticism of exemplar theories of history, and focuses on Droysen’s claim that the goal underlying (...) historical writing and reading should be the development of the subjective capacity to think historically. In addition, Assis examines the connections and disconnections between Droysen’s theory of historical thinking, his practice of historical thought, and his political activism. Ultimately, Assis not only shows how Droysen helped reinvent the relationship between historical knowledge and human agency, but also traces some of the contradictions and limitations inherent to that project.

We expound an alternative to the Copenhagen interpretation of the formalism of nonrelativistic quantum mechanics. The basic difference is that the new interpretation is formulated in the language of epistemological realism. It involves a change in some basic physical concepts. The ψ function is no longer interpreted as a probability amplitude of the observed behaviour of elementary particles but as an objective physical field representing the particles themselves. The particles are thus extended objects whose extension varies in time according to (...) the variation of ψ. They are considered as fundamental regions of space with some kind of nonlocality. Special consideration is given to the Heisenberg relations, the Einstein-Podolsky- Rosen correlations, the reduction process, the problem of measurement, and the quantum-statistical distributions.

Short intellectual biography of Alexandre Herculano. English translation available.

Determinism is established in quantum mechanics by tracing the probabilities in the Born rules back to the absolute (overall) phase constants of the wave functions and recognizing these phase constants as pseudorandom numbers. The reduction process (collapse) is independent of measurement. It occurs when two wavepackets overlap in ordinary space and satisfy a certain criterion, which depends on the phase constants of both wavepackets. Reduction means contraction of the wavepackets to the place of overlap. The measurement apparatus fans out the (...) incoming wavepacket into spatially separated eigenpackets of the chosen observable. When one of these eigenpackets together with a wavepacket located in the apparatus satisfy the criterion, the reduction associates the place of contraction with an eigenvalue of the observable. The theory is nonlocal and contextual. Keywords:. (shrink)

The spin-statistics connection is derived in a simple manner under the postulates that the original and the exchange wave functions are simply added, and that the azimuthal phase angle, which defines the orientation of the spin part of each single-particle spin-component eigenfunction in the plane normal to the spin-quantization axis, is exchanged along with the other parameters. The spin factor (−1)2s belongs to the exchange wave function when this function is constructed so as to get the spinor ambiguity under control. (...) This is achieved by effecting the exchange of the azimuthal angle by means of rotations and admitting only rotations in one sense. The procedure works in Galilean as well as in Lorentz-invariant quantum mechanics. Relativistic quantum field theory is not required. (shrink)

A characterization result of dilation in terms of positive and negative association admits an extremal counterexample, which we present together with a minor repair of the result. Dilation may be asymmetric whereas covariation itself is symmetric. Dilation is still characterized in terms of positive and negative covariation, however, once the event to be dilated has been specified.

In this article, we propose the Fair Priority Model for COVID-19 vaccine distribution, and emphasize three fundamental values we believe should be considered when distributing a COVID-19 vaccine among countries: Benefiting people and limiting harm, prioritizing the disadvantaged, and equal moral concern for all individuals. The Priority Model addresses these values by focusing on mitigating three types of harms caused by COVID-19: death and permanent organ damage, indirect health consequences, such as health care system strain and stress, as well as (...) economic destruction. It proposes proceeding in three phases: the first addresses premature death, the second long-term health issues and economic harms, and the third aims to contain viral transmission fully and restore pre-pandemic activity. -/- To those who may deem an ethical framework irrelevant because of the belief that many countries will pursue "vaccine nationalism," we argue such a framework still has broad relevance. Reasonable national partiality would permit countries to focus on vaccine distribution within their borders up until the rate of transmission is below 1, at which point there would not be sufficient vaccine-preventable harm to justify retaining a vaccine. When a government reaches the limit of national partiality, it should release vaccines for other countries. -/- We also argue against two other recent proposals. Distributing a vaccine proportional to a country's population mistakenly assumes that equality requires treating differently situated countries identically. Prioritizing countries according to the number of front-line health care workers, the proportion of the population over 65, and the number of people with comorbidities within each country may exacerbate disadvantage and end up giving the vaccine in large part to wealthy nations.

We present a game mechanic called pseudo-visibility for games inhabited by non-player characters (NPCs) driven by reinforcement learning (RL). NPCs are incentivized to pretend they cannot see pseudo-visible players: the training environment simulates an NPC to determine how the NPC would act if the pseudo-visible player were invisible, and penalizes the NPC for acting differently. NPCs are thereby trained to selectively ignore pseudo-visible players, except when they judge that the reaction penalty is an acceptable tradeoff (e.g., a guard might accept (...) the penalty in order to protect a treasure because losing the treasure would hurt even more). We describe an RL agent transformation which allows RL agents that would not otherwise do so to perform some limited self-reflection to learn the training environments in question. (shrink)

In this paper, I first present an overview of Asay’s _A Theory of Truthmaking_, highlighting what I take to be some of its most attractive features, especially his re-invigoration of the ontological understanding of truthmaking and his defence of ontology-first truthmaking over explanation-first truthmaking. Then, I articulate what I take to be a puzzling potential inconsistency: (a) he appeals to considerations to do with aboutness in criticising how well ontological views account for truth while (b) ruling out aboutness from the (...) right account of truthmaking. He argues, instead, that necessitation is both necessary and sufficient for truthmaking (§3.3). I suggest that adding aboutness to one’s account in the right way is not just compatible with but important for ontology-first truthmaking. I do all this to invite Asay to clarify his position on these matters. Overall, Asay’s worldview displays the fruitfulness of an ontologically serious approach to metaphysics that puts truthmaking centre-stage. (shrink)

The present narrative review seeks to unravel where we are now, and where we need to go to delineate the active ingredients in psychotherapy delivered by conversational agents (e.g., chatbots). While psychotherapy delivered by conversational agents has shown promising effectiveness for depression, anxiety, and psychological distress across several randomized controlled trials, little emphasis has been placed on the therapeutic processes in these interventions. The theoretical framework of this narrative review is grounded in prominent perspectives on the active ingredients in psychotherapy. (...) Based on search terms derived from various theoretical perspectives, we conducted a systematic literature search of four scientific databases and identified 17 studies. Across the selected studies, three themes emerged: relationship variables, emotional venting, and cognitive factors. While methodological issues compromise the epistemic value of this evidence base, core questions also remain to be answered. Such questions include, but are not limited to, whether humans can form affectionate bonds to inanimate beings and whether these kind of mental health treatments should be understood as psychotherapy or something else. Researchers should therefore be cautious when applying theories of psychotherapy in the realm of conversational agents. We conclude the paper by introducing recommendations for future research, which we hope will help instigate methodologically sound studies in this field. (shrink)

At the end of the 19th century, most professional historians – wherever they existed – deemed history to be a form of knowledge ruled by a method that bears no resemblance with those most commonly traceable in the natural sciences. The bulk of the historian’s task was then frequently regarded as being the application of procedures frequently referred to as ‘historical method’. In the context of such an emerging interest on historical methods and methodology, at least three textbooks stand out: (...) Johann Gustav Droysen’s Grundriss der Historik (Outline of the Theory of History), Ernst Bernheim’s Lehrbuch der historischen Methode (Handbook of Historical Method), and Charles Langlois and Charles Seignobos’s Introduction aux études historiques (Introduction to the Study of History). These books were quite influential in Germany, France, and elsewhere, and they very much helped promote a general idea of historical method that would become relatively consensual among historians of many nationalities by the early 20th century. Such a relative agreement on historical method sponsored both the communication and the development of a sense of disciplinary identity among historians trained within different and sometimes conflicting national traditions. It was then partially extended, partially challenged, and surely made more complex when, from the 1920s on, social and economic historians became a good part of the historiographical establishment in many countries. -/- The three books by Droysen, Bernheim, and Langlois and Seignobos were already pieced together by Rolf Torstendahl, who studied them as a group of texts that, despite their differences, contributed to shape the developments outlined above. However, Torstendahl’s primary aim was to show how Droysen, Bernheim, and Seignobos all resorted to ‘method’ as a way to circumvent skepticism against the possibility of historical knowledge, rather than investigate the internal interrelationships between the three texts. In this chapter I follow precisely this latter, not yet taken, road, focusing on crucial cross-references between the Grundriss, the Lehrbuch, and the Introduction. I intend to show that, at a general level, the schemes of historical method found in these texts are largely convergent, and that this convergence is due to Bernheim’s reading of Droysen and to Langlois and Seignobos’s reading of Bernheim. I will attempt to do it through a regressive approach that starts with an analysis of the Introduction. Aspects of the editorial history and circulation of the three texts will also be briefly addressed, as a way to illustrate their special importance within the framework of early 20th century historical theory. Because my argument calls for a focus on the most general lines of Droysen’s, Bernheim’s, and Langlois and Seignobos’s schemes of historical method, I will, for the sake of consistency, refrain from analysing in-depth the complex epistemological and ontological arguments in which those schemes are nested.

Since W. B. Gallie introduced the notion of essentially contested concepts (ECCs) in 1956, social science scholars have increasingly used his framework to analyze key concepts drawing “endless disputes” from contestant users. Despite its merits, the ECC framework has been limited by a neglect of social, cultural, and political contexts, the invisibility of actors, and its ahistorical character. To understand how ECCs evolve and change over time, I use a conceptual history approach to study the concept of philanthropy, recently labeled (...) as an ECC. Using France during classical modernity as a case study, I analyze key events and actors from the concept’s inception in 1712 as a virtue of the Enlightenment to its triumph after 1789 as a secular alternative to Catholic charity, until its decline at the end of the nineteenth century as a new consensus emerged around the concept of solidarity. By introducing the notion of historically contested concepts, I make several contributions to research on ECCs, conceptual contestation, and conceptual change. (shrink)

All parties involved in researching, developing, manufacturing, and distributing COVID-19 vaccines need guidance on their ethical obligations. We focus on pharmaceutical companies' obligations because their capacities to research, develop, manufacture, and distribute vaccines make them uniquely placed for stemming the pandemic. We argue that an ethical approach to COVID-19 vaccine production and distribution should satisfy four uncontroversial principles: optimising vaccine production, including development, testing, and manufacturing; fair distribution; sustainability; and accountability. All parties' obligations should be coordinated and mutually consistent. For (...) instance, companies should not be obligated to provide host countries with additional booster shots at the expense of fulfilling bilateral contracts with countries in which there are surges. Finally, any satisfactory approach should include mechanisms for assurance that all parties are honouring their obligations. This assurance enables countries, pharmaceutical companies, global organisations, and others to verify compliance with the chosen approach and protect ethically compliant stakeholders from being unfairly exploited by unethical behaviour of others.

In recent years, semiotics has become an innovative theoretical framework in mathematics education. The purpose of this article is to show that semiotics can be used to explain learning as a process of experimenting with and communicating about one's own representations of mathematical problems. As a paradigmatic example, we apply a Peircean semiotic framework to answer the question of how students learned the concept of "distribution" in a statistics course by "diagrammatic reasoning" and by developing "hypostatic abstractions," that is by (...) forming new mathematical objects which can be used as means for communication and further reasoning. Peirce's semiotic terminology is used as an alternative for notions such as modeling, symbolizing, and reification. We will show that it is a precise instrument of analysis with regard to the complexity of learning and of communication in mathematics classroom. (shrink)

The role of the new concepts in the problems of measurement and of the Einstein-Podolsky-Rosen correlations is described.

A central tenet of truthmaker theory is that necessitation is necessary for truthmaking (NEC). This paper defends NEC in a novel, piecemeal way, namely by responding to a potential counterexample involving a changing past. If Carter won a race at t1 but is later disqualified at t2, then Carter no longer won at t1. A wholly past event seems to have changed in the future. The event makes ‘Carter won the race at t1’ (RACE) true between t1‐2 but fails to (...) make it true at t2. So, we have a potential counterexample to necessitation: a truthmaker of RACE fails in another context to make the same truthbearer RACE true. I argue that the best solution to this challenge is not that there are different truthbearers at t1‐2 and t2 (the semantic response), or that RACE was never true because of the future disqualification or will always be true despite the future disqualification. The best solution is to accept that the past can change: past events can change based on what happens in the future (e.g., via their effects). This paper's novel defence of necessitation will illustrate the importance of utilising explicitly ontological and commonsensical tools in accounting for truth. (shrink)

There is no paradox with Schrödinger’s cat in a realist interpretation. In particular, a closer look at the temporal aspect shows that the two macroscopic wave functions (alive and dead) of Schrödinger’s cat are not to be compared with two superposed parts of a microscopic quantum wave function.

Why microscopic objects exhibit wave properties (are delocalized), but macroscopic do not (are localized)? Traditional quantum mechanics attributes wave properties to all objects. When complemented with a deterministic collapse model (Quantum Stud.: Math. Found. 3, 279 (2016)) quantum mechanics can dissolve the discrepancy. Collapse in this model means contraction and occurs when the object gets in touch with other objects and satisfies a certain criterion. One single collapse usually does not suffice for localization. But the object rapidly gets in touch (...) with other objects in a short time, leading to rapid localization. Decoherence is not involved. (shrink)

The perceptual symbol system view assumes that perceptual representations have a role-argument structure. A role-argument structure is often incorporated into amodal symbol systems in order to explain conceptual functions like abstraction and rule use. The power of perceptual symbol systems to support conceptual functions is likewise rooted in its use of structure. On Barsalou's account, this capacity to use structure (in the form of frames) must be innate.
