In this chapter, Colin Marshall argues that Schopenhauer’s views about the foundations of morality pose important challenges for five tenets of contemporary metaethics. After presenting these challenges, Marshall explores the potential viability of contemporary Schopenhauerian approaches to metaethics that would leave aside his radical metaphysical monism.

This chapter explores a philosophical hypothesis about the nature of (some) probabilities encountered in social sciences. It should be of interest to those with philosophical concerns about the foundations of probability, and to social scientists and philosophers of science who are somewhat puzzled by the nature of probability in social domains. As will become clear below, the chapter is not intended as a contribution to an empirical methodology such as a particular way of applying statistics.

Neopragmatism has been accused of having ‘an experience problem’. This paper begins by outlining Hume's understanding of perception according to which ideas are copies of impressions thought to constitute a direct confrontation with reality. This understanding is contrasted with Peirce's theory of perception according to which percepts give rise to perceptual judgments which do not copy but index the percept (just as a weather-cock indicates the direction of the wind). Percept and perceptual judgment thereby mutually inform and correct one another, (...) as the perceiver develops mental habits of interpreting their surroundings, so that, in this theory of perception, as Peirce puts it: “[n]othing at all…is absolutely confrontitional”. Paul Redding has argued that Hegel’s “idealist understanding of logical form” ran deeper than Kant’s in recognising that Mind is essentially embodied and located, and therefore perspectival. Peirce’s understanding arguably dives deeper still in distributing across the space of reasons (and thus Being) not just Mind’s characteristic features of embodiedness and locatedness, but also its infinite corrigibility.

Robustly realistic metaphysical readings of Kant’s mature views have become popular in recent years, largely because of the apparent coherence of applying unschematized categories like that of causation to things in themselves. There is, however, an overlooked problem that arises even for robust realist readings that privilege unschematized categories. The problem is that Kant provides all the elements for what is now called a ‘debunking explanation’ of metaphysical representations of things in themselves. His account of the categories as arising from (...) mere forms of judgment, and being applied primarily for the unity of consciousness, is detached from the issue of whether there are causes among things in themselves. This detachment seems to imply that it would be a huge coincidence if unschematized categories corresponded to any such causes. After making this argument, using the category of causation as my central case, I consider three potential responses: that Kant’s account implicitly appeals to things in themselves’ causation, that Kant has a separate account of non-coincidental representation, and that Kant’s account is merely incomplete in a way that poses no debunking threat. None of these responses, I argue, are successful, so I conclude that either robustly realistic metaphysical readings are mistaken, or there is internal incoherence in Kant’s views. (shrink)

What a person is doing often depends on that person’s thought about what they are doing, or about the wider circumstances of their action. For example, whether my killing is murder or manslaughter depends, in part, on whether I understand that what I am doing is killing you, and on whether I understand that my killing is unjustified. Similarly, if I know that the backpack I am taking is yours, then my taking it may be an act of theft; but (...) it is not theft if I simply mistook your backpack for my own. And if I don’t know that in signing a document I’m promising to do some thing, then in signing it I’m not promising to do this at all. -/- According to Elizabeth Anscombe, a central task of philosophical psychology is to articulate this dependency of action on thought. And in a range of papers published during the 1960s, Anscombe sought to elucidate various aspects of this dependency. In this paper we give a systematic overview of how Anscombe understands this dependency, and in the process reveal the conceptual framework underlying Anscombe’s thinking about perception, desire, intention, voluntariness, responsibility, guilt, and sin.

Mortality seems important in explaining the value of virtues. It seems that courage is valuable because we face dangers of death and pain, just as it seems temperance is valuable because we can harm our health by overindulgence. This poses a serious problem for Christian ethics. If the virtues are valuable because they ameliorate harms stemming from limitations like mortality, then the virtues will lose much of their value in the new creation, where those limitations are no more. This chapter (...) argues that the threat is serious, and requires the rethinking of the fundamental value of the virtues. The virtues are not, first and foremost, the dispositions that allow us to improve the broken world we live in, but precisely those dispositions necessary for enjoying ideal or perfect conditions.

Discussions over whether these natural kinds exist, what is the nature of their existence, and whether natural kinds are themselves natural kinds aim to not only characterize the kinds of things that exist in the world, but also what can knowledge of these categories provide. Although philosophically critical, much of the past discussions of natural kinds have often answered these questions in a way that is unresponsive to, or has actively avoided, discussions of the empirical use of natural kinds and (...) what I dub “activities of natural kinding” and “natural kinding practices”. The natural kinds of a particular discipline are those entities, events, mechanisms, processes, relationships, and concepts that delimit investigation within it—but we might reasonably ask: How are these natural kinds discovered?, How are they made?, Are they revisable?, and Where do they come from? A turn to natural kinding practices reveals a new set of questions open for investigation: How do natural kinds explain through practice?, What are natural kinding practices and classifications and why should we care?, What is the nature of natural kinds viewed as a set of activities?, and How do practice approaches to natural kinds shape and reconfigure scientific disciplines? Natural kinds have traditionally been discussed in terms of how they classify the contents of the world. The metaphysical project has been one which identifies essences, laws, sameness relations, fundamental properties, and clusters of family resemblances and how these map out the ontological space of the world. But actually how this is done has been less important in the discussion than the resultant categories that are produced. I aim to rectify these omissions and suggest a new metaphysical project investigating kinds in practice. (shrink)

Although certain recent developments in mendacious political manipulation of public discourse are horrifying to the academic mind, I argue that we should not panic. Charles Peirce’s pragmatist epistemology with its teleological arc, long horizon, and rare balance between robust realism and contrite fallibilism offers guidance to weather the storm, and perhaps even see it as inevitable in our intellectual development. This paper explores Peirce’s classic “four methods of fixing belief”, which takes us on an entertaining and still very pertinent tour (...) through tenacity, authority and a priori speculation to the method of science – the only method which is both public and self-correcting. Although in the West we (mostly) proudly self-conceive as living in a ‘scientific age’, I argue that this is premature. Precisely insofar as we treat the misbehavior of governments as a harbinger of doom, we remain trapped in authoritarian modes of thinking which Peirce identified with medievalism, although modernity is increasingly quickening around us in worldwide information-sharing practices that are shaped entirely by mutual help. With this framework in mind, many tactics of recent media are most helpfully seen as belonging not to a post-truth, but a pre-truth stage of human intellectual development. Advice on this is sought from Plato, who of course also faced a world that was ‘pre-academic’. (shrink)

This paper offers both a criticism of and a novel alternative perspective on current ontologies that take race to be something that is either static and wholly evident at one’s birth or preformed prior to it. In it I survey and critically assess six of the most popular conceptions of race, concluding with an outline of my own suggestion for an alternative account. I suggest that race can be best understood in terms of one’s experience of his or her body, (...) one’s interactions with other individuals, and one’s experiences within particular cultures and societies. This embeddedness of human experience has been left out of most discussions of race which tie race to a set of characteristics (either biologically or sociologically defined). To rectify this omission, I articulate what I call the “physiosocial” view of race. This emphasizes the situatedness of human experience, the reciprocal and dynamic nature of the racial identities of individuals and groups. Approaching racial identity in this way entails a union of two historically uncomfortable partners: biological and sociological conceptions of race. If successful, this philosophical stance may illuminate the process of racial self-ascription as well as provide an explanation for the potential changeability of an individual’s racial identity at different times and at different places.

Apoha, a Sanskrit term meaning exclusion, was used by the late fifth- to early sixth-century Buddhist philosopher Dignā ga as a keystone in his theory of denotation. According to Dignā ga, a word denotes its meaning through the exclusion of what is other (anyā poha). This idea provoked celebration and controversy that would last through the end of Sanskritic Indian Buddhism. In the hands of Dignā ga’s successor Dharmakīrti (seventh century), who developed what became the normative version of this theory, (...) apoha leverages the fact that a causally efficacious real thing is different from everything else to describe how the interaction between living beings and their worlds produces judgements that are either shared or not in accord with the various factors contributing to the judgement’s formation. Dharmakīrti argues that there’s an infinite number of ways that a real thing could be conceptualised since each real thing is different from the infinite expanse of other real things. Acting toward a real thing requires delimiting the scope of what one ignores so that just some of the differences are left over. A living being can afford to ignore the differences between the differences that are left over in this exclusion because these differences don’t impact the specific goal based on which the living being judges an object to be efficacious or not.

This paper addresses some apparent philosophical tensions between realism and enactivism by means of Charles Peirce’s pragmatism. Enactivism’s Mind-Life Continuity thesis has been taken to commit it to some form of anti-realist ‘world-construction’ which has been considered controversial. Accordingly, a new realist enactivism is proposed by Zahidi (_Phenomenology and the Cognitive Sciences,_ _13_(3), 461–475, 2014 ), drawing on Ian Hacking’s ‘entity realism’, which places subjects in worlds comprised of the things that they can successfully manipulate. We review this attempt, and (...) argue that whilst Zahidi rightly urges enactivists towards ‘internal realism’, he cannot sustain a non-negotiable aspect of realism that is crucial for scientific progress – the claim that multiple subjects inhabit _the same world_. We explore Peirce’s pragmatism as an alternative solution, foregrounding his distinction between existence and reality, and his inquiry-based account of cognition. These theoretical innovations, we argue, fruitfully generalize Zahidi’s _manipulation-based_ enactivist realism to a richer, _inquiry-based_ enactivist realism. We explore how this realism’s pan-species monism about truth encourages and supports the investigation of non-human animal cognition, and conclude by considering some implications of our discussion for long-standing realism debates within pragmatism.

Kant's philosophy promises to explain various synthetic a priori claims. Yet, as several of his commentators have noted, it is hard to see how these explanations could work unless they themselves rested on unexplained synthetic a priori claims. Since Kant appears to demand explanations for all synthetic a priori claims, it would seem that his project fails on its own terms. I argue, however, that Kant holds that explanations are required only for synthetic a priori claims about (purportedly) experience-independent entities, (...) and that his project rests on a rationalist method of reflection that justifies certain basic synthetic a priori claims.

The account of natural kinds as stable property clusters is premised on the possibility of separating the epistemic value of natural kinds from their underlying metaphysics. On that account, the co-instantiation of any sub-cluster of the properties associated with a given natural kind raises the probability of the co-instantiation of the rest, and this clustering of property instantiation is invariant under all relevant counterfactual perturbations. We argue that it is not possible to evaluate the stability of a cluster of properties (...) without taking stock of the metaphysical picture used to account for that stability. Thus, even on the stable property cluster account, the epistemic value of natural kinds remains partly grounded in their metaphysical status. (shrink)

This book offers a ground-up defense of objective morality, drawing inspiration from a wide range of philosophers, including John Locke, Arthur Schopenhauer, Iris Murdoch, Nel Noddings, and David Lewis. The core claim is compassion is our capacity to perceive other creatures' pains, pleasures, and desires. Non-compassionate people are therefore perceptually lacking, regardless of how much factual knowledge they might have. Marshall argues that people who do have this form of compassion thereby fit a familiar paradigm of moral goodness. His (...) argument involves the identification of an epistemic good which Marshall dubs "being in touch". To be in touch with some property of a thing requires experiencing it in a way that reveals that property - that is, experiencing it as it is in itself. Only compassion, Marshall argues, lets us be in touch with others' motivational mental properties. -/- This conclusion about compassion has two important metaethical consequences. First, it generates an answer to the question ";Why be moral?", which has been a central philosophical concern since Plato. Second, it provides the keystone for a novel form of moral realism. This form of moral realism has a distinctive set of virtues: it is anti-relativist, naturalist, and able to identify a necessary connection between moral representation and motivation. The view also implies that there is an epistemic asymmetry between virtuous and vicious agents, according to which only morally good people can fully face reality. (shrink)

Charles Peirce's diagrammatic logic — the Existential Graphs — is presented as a tool for illuminating how we know necessity, in answer to Benacerraf's famous challenge that most ‘semantics for mathematics’ do not ‘fit an acceptable epistemology’. It is suggested that necessary reasoning is in essence a recognition that a certain structure has the particular structure that it has. This means that, contra Hume and his contemporary heirs, necessity is observable. One just needs to pay attention, not merely to individual (...) things but to how those things are related in larger structures, certain aspects of which relations force certain other aspects to be a certain way.

This entry explores Charles Peirce's account of truth in terms of the end or ‘limit’ of inquiry. This account is distinct from – and arguably more objectivist than – views of truth found in other pragmatists such as James and Rorty. The roots of the account in mathematical concepts is explored, and it is defended from objections that it is (i) incoherent, (ii) in its faith in convergence, too realist and (iii) in its ‘internal realism’, not realist enough.

This paper investigates the limitations of exclusively reducing community-based advantages to individual goods, while highlighting the intricate dynamics that shape the well-being of both individuals and the collective. Drawing inspiration from Aristotelian distinctions, the argument challenges Hartney's perspective by emphasizing the inherent value of corrective justice within communities. It explores the interplay between distributive and corrective justice, asserting that the implementation of corrective measures, crucial for societal harmony, transcends individual advantages. The discourse extends to the multifaceted nature of community-based benefits, (...) encompassing shared values, common goods, social cohesion, and collective endeavors. Neglecting these complexities oversimplifies the intricate web of societal interactions, thereby diminishing the intrinsic value of communities in fostering the well-being of their members. The abstract advocates for a holistic approach that acknowledges the interconnected and collective nature of these benefits to achieve a comprehensive understanding of societal flourishing. (shrink)

In this chapter, I argue that Kant can be read as holding that "ought" judgments follow from certain "is" judgments by mere analysis. More specifically, I defend an interpretation according to which (1) Kant holds that “S ought to F” is analytically equivalent to “If, as it can and would were there no other influences on the will, S’s faculty of reason determined S’s willing, S would F” and (2) Kant’s notions of reason, the will, and freedom are all fundamentally (...) non-normative. Not only does this reading have significant textual support, but, I claim, it also sheds light on why Kant takes freedom and morality to mutually imply one another. Moreover, while Kant does take there to be a gap between moral judgments and empirical descriptive statements, that gap is consistent with the analysis in question. I conclude by arguing that this rejection of the is-ought gap is not as philosophically implausible as it might seem, with a focus on G.E. Moore and Hume’s arguments for certain ‘gaps’ between the normative and the non-normative. (shrink)

It seems possible to know that a mathematical claim is necessarily true by inspecting a diagrammatic proof. Yet how does this work, given that human perception seems to just (as Hume assumed) ‘show us particular objects in front of us’? I draw on Peirce’s account of perception to answer this question. Peirce considered mathematics as experimental a science as physics. Drawing on an example, I highlight the existence of a primitive constraint or blocking function in our thinking which we might (...) call ‘the hardness of the mathematical must’. (shrink)

Homology is a natural kind concept, but one that has been notoriously elusive to pin down. There has been sustained debate over the nature of correspondence and the units of comparison. But this continued debate over its meaning has focused on defining homology rather than on its use in practice. The aim of this chapter is to concentrate on the practices of homologizing. I define “homologizing” to be a concept-in-use. Practices of homologizing are kinds of rule following, the satisfaction of (...) which demarcates a category—that of being a homologue. Identifying, explaining, discovering, and understanding are exchanges that connect practice to concept through the performance of a rule by practitioners. These practices are constitutive of natural kinding activities. If homologizing is a kind of kinding, consideration of these practices of discovery, tracking, and identification not only clarifies the meaning, use, and progression of the concept of homology, but provides further understanding of the processes and progression of natural kinds and kinding practices in general.

Ethnobotanical research provides ample justification for comparing diverse biological nomenclatures and exploring ways that retain alternative naming practices. However, how (and whether) comparison of nomenclatures is possible remains a subject of discussion. The comparison of diverse nomenclatural practices introduces a suite of epistemic and ontological difficulties and considerations. Different nomenclatures may depend on whether the communities using them rely on formalized naming conventions; cultural or spiritual valuations; or worldviews. Because of this, some argue that the different naming practices may not (...) be comparable if the ontological commitments employed differ. Comparisons between different nomenclatures cannot assume that either the naming practices or the object to which these names are intended to apply identifies some universally agreed upon object of interest. Investigating this suite of philosophical problems, I explore the role grey nomenclatures play in classification. ‘Grey nomenclatures’ are defined as those that employ names that are either intentionally or accidentally non-Linnaean. The classification of the lichen thallus (a symbiont) has been classified outside the Linnaean system by botanists relying on the International Code of Nomenclature for algae, fungi, and plants (ICN). But, I argue, the use of grey names is not isolated and does not occur exclusively within institutionalized naming practices. I suggest, ‘grey names’ also aptly describe nomenclatures employed by indigenous communities such as the Samí of Northern Finmark, the Sherpa of Nepal, and the Okanagan First Nations. I pay particular attention to how naming practices are employed in these communities; what ontological commitments they hold; for what purposes are these names used; and what anchors the community’s nomenclatural practices. Exploring the history of lichen naming and early ethnolichenological research, I then investigate the stakes that must be considered for any attempt to preserve, retain, integrate, or compare the knowledge contained in both academically formalized grey names and indigenous nomenclatures in a way that preserves their source-specific informational content.

Pragmatism’s heartening recent revival (spearheaded by Richard Rorty’s bold intervention into analytic philosophy Philosophy and the Mirror of Nature) has coalesced into a distinctive philosophical movement frequently referred to as ‘neopragmatism’. This movement interprets the very meaning of pragmatism as rejection of metaphysical commitments: our words do not primarily serve to represent non-linguistic entities, but are tools to achieve a range of human purposes. A particularly thorough and consistent version of this position is Huw Price’s global expressivism. We here critically (...) appraise Price’s understanding of a commitment to pragmatism as a rejection of metaphysics, and argue that such rejection is not as easy or desirable as Price claims. First we argue that Price’s global expressivism itself draws on significant metaphysical assumptions (a ‘word-world’ dualism, and a nominalism concerning the meaning of general terms). Then we seek to resolve neopragmatist anxieties about metaphysics by arguing that metaphysics is indispensable for pragmatist philosophizing insofar as it seeks ways for human beings to realise themselves through practices of understanding reality and their place in it. If, as we argue, metaphysics consists in a maximally general inquiry into the nature and structure of reality, to try to block it seems a puzzling exercise in epistemic self-harm. (shrink)

Charles Peirce famously divided all signs into icons, indices and symbols. The past few decades have seen mainstream analytic philosophy broaden its traditional focus on symbols to recognise the so-called essential indexical. Can the moral now be extended to icons? Is there an “essential icon”? And if so, what exactly would be essential about it? It is argued that there is and it consists in logical form. Danielle Macbeth’s radical new “expressivist” interpretation of Frege’s logic and Charles Peirce’s existential graphs (...) are mobilized in support of this claim. (shrink)

Enactivism has influentially argued that the traditional intellectualist ‘act-content’ model of intentionality is insufficient both phenomenologically and naturalistically, and minds are built from world-involving bodily habits – thus, knowledge should be regarded as more of a skilled performance than an informational encoding. Radical enactivists have assumed that this insight must entail non-representationalism concerning at least basic minds. But what if it could be shown that representation is itself a form of skilled performance? I sketch the outline of such an account (...) from the perspective of Peirce’s pragmatist semiotics, which theorises signs as habits of associating specific cues with appropriate acts and schemas of ensuing experience. Within this framework, I argue, a naturalistic account of propositional structure can be constructed which transcends the symbolic – and in some instances even the linguistic – sphere, and offers new insights regarding the Information Processing Challenge, and the Hard Problem of Content.

Ecological Psychology and Enactivism both challenge representationist cognitive science, but the two approaches have only begun to engage in dialogue. Further conceptual clarification is required in which differences are as important as common ground. This paper enters the dialogue by focusing on important differences. After a brief account of the parallel histories of Ecological Psychology and Enactivism, we cover incompatibility between them regarding their theories of sensation and perception. First, we show how and why in ecological theory perception is, crucially, (...) not based on sensation. We elucidate this idea by examining the biological roots of work in the two fields, concentrating on Gibson and Varela and Maturana. We expound an ecological critique of any sensation-based approach to perception by detailing two topics: classic retinal image theories and perception in single-celled organisms. The second main point emphasizes the importance of the idea of organism-environment mutuality and its difference from structural coupling of sensations and motor behavior. We point out how ecological - phenomenological methods of inquiry grow out of mutualism and compare Gibson’s idea of visual kinesthesis to Merleau-Ponty’s idea of the lived body. Third, we conclude that Ecological Psychology and varieties of Enactivism are laying down different paths to pursue related goals. Thus, convergence of Ecological Psychology and Enactivism is not possible given their conflicting assumptions, but cross-fertilization is possible and desirable. (shrink)

In this paper, we examine how a research institution’s social structure and academic opinion leaders’ presence shaped the early adoption of a scientific innovation. Our case considers the early engagement of mathematical economists at the Cowles Commission with John von Neumann and Oskar Morgenstern’s Theory of Games and Economic Behavior. We argue that scholars with administrative leadership functions who were not only scientifically but also organizationally central – in our case the director of research Jacob Marschak – played a crucial (...) role in promoting the adoption of the Theory of Games. We support our argument with a scientometric analysis of all acknowledgments made in 488 papers published from 1944 to 1955 in the two main paper series at Cowles. We apply blockmodeling techniques to the acknowledgments network to reconstruct the formal and informal social structure at Cowles at the time. Our findings suggest that studies of the early adoption of scientific theories benefit from complementary perspectives on the role of academic leaders and scientists. Our study reveals the importance of formal and informal social structures and the agenda of administrative leaders in these structures to explain their adoption. (shrink)

This paper explores how Charles Peirce’s habit-based epistemology leads him to theorise perception. I show how Peirce’s triadic semiotic analysis of perceptual judgment renders his theory of perception neither a representationalism nor a relationism /direct realism, but an interesting hybrid of the two. His view is also extremely interesting, I argue, in the way that by analysing symbols as habits it refuses the common assumption that perception is an affair best understood synchronically, as a ‘language-entry event’. Relatedly, I extend previous (...) work (Legg 2008) which argues that Peirce’s epistemology counts as a ‘hyperinferentialism’ in Robert Brandom’s terms, but this does not mean that Peirce’s theory of perception cannot accommodate unmediated contact with reality - what Peirce called ‘the outward clash’.

Would be fairer to call Peirce’s philosophy of language “extensionalist” or “intensionalist”? The extensionalisms of Carnap and Quine are examined, and Peirce’s view is found to be prima facie similar, except for his commitment to the importance of “hypostatic abstraction”. Rather than dismissing this form of abstraction (famously derided by Molière) as useless scholasticism, Peirce argues that it represents a crucial (though largely unnoticed) step in much working inference. This, it is argued, allows Peirce to transcend the extensionalist-intensionalist dichotomy itself, (...) through his unique triadic analysis of reference and meaning, by transcending the distinction between (as Quine put it) “things” and “attributes”.

A feminist standpoint addresses the ideals or norms and attendant practices involved in science and knowledge with a mind to lived experiences of oppression. That such matters of social context and awareness of that context influence the ability of individual people to know their worlds constitutes the Situated Knowledge Thesis (Intemann 2016; Wylie 2003). Situated knowledges provide the evidence and inspiration for the central epistemological tenet of feminist standpoint theory. Individuals and liberatory communities obtain the epistemic advantage of a standpoint (...) through an Outside- In Process of thinking, drawing into science and knowledge the “outside” values and experiences of marginalized people. Outside- in thinking manifests both as a theory and a methodology in feminist philosophy of science. (shrink)

Political persuasion can express moral respect. In this article, however, I rely on two psychological assumptions to argue that political persuasion is generally prima facie disrespectful: (1) that we maintain our political beliefs largely for non-epistemic, personal reasons and (2) that our political beliefs are connected to our epistemic esteem. Given those assumptions, a persuader can either ignore the relevant personal reasons, explicitly address them, or implicitly address them. Ignoring those reasons, I argue, constitutes prima facie insensitivity. Explicitly addressing them (...) constitutes a form of prima facie incivility. Finally, implicitly addressing them covertly treats those personal reasons as psychological puppet strings, constituting prima facie objectionable manipulation. This prima facie insensitivity, incivility, and manipulation are each prima facie failures of respect, either for the persuadee’s rationality or for their agency. Political persuasion can sometimes be all-things-considered justified, but these moral hazards can produce reasonable guilt, resentment, and blowback. (shrink)

I defend the thesis that friendship can constitutively require epistemic irrationality against a recent, forceful challenge, raised by proponents of moral and pragmatic encroachment. Defenders of the “encroachment strategy” argue that exemplary friends who are especially slow to believe that their friends have acted wrongly are simply sensitive to the high prudential or moral costs of falsely believing in their friends’ guilt. Drawing on psychological work on epistemic motivation (and in particular on the notion of “need for closure”), I propose (...) a different picture of what friendship requires in the doxastic realm. I argue that contrary to what the encroachment strategy suggests, exemplary friends’ belief formation ought not be guided by a concern with accuracy or error avoidance, but instead by a need to avoid a “specific closure” – namely, a need to avoid concluding in their friends’ guilt. I propose that exemplary friendship often generates a defeasible, doxastic obligation to exemplify such a need, despite its inherent corrupting effects on exemplary friends’ epistemic faculties.

Feminists note an association of arguing with aggression and masculinity and question the necessity of this connection. Arguing also seems to some to identify a central method of philosophical reasoning, and gendered assumptions and standards would pose problems for the discipline. Can feminine modes of reasoning provide an alternative or supplement? Can overarching epistemological standards account for the benefits of different approaches to arguing? These are some of the prospects for argumentation inside and outside of philosophy that feminists consider. -/- (...) The further concern is that the academic study of argumentation – in philosophy and other disciplines – has failed to account for the type of reasoning needed for social justice movements. What resources for addressing these concerns can be found in informal logic and interdisciplinary argumentation theory? Since part of the perceived problem derives from assuming that arguing is a contest, are more collaborative epistemological frameworks better? Can regular politeness or civility hedge against undesirable tendencies of argumentation? Can “critical thinking” pedagogy involving argument educations answer the needs of social justice? (shrink)

Schopenhauer repeatedly claims that suicide is both foolish and futile. But while many commentators have expressed sympathy for his charge of foolishness, most regard his charge of futility as indefensible even within his own system. In this paper, I offer a defense of Schopenhauer’s futility charge, based on metaphysical and psychological considerations. On the metaphysical front, Schopenhauer’s view implies that psychological connections extend beyond death. Drawing on Parfit’s discussion of personal identity, I argue that those connections have personal significance, such (...) that suicide does not allow one, as Hamlet hopes, simply “not to be.” On the psychological front, I argue that a distinction between agents’ intentions and underlying desires makes room for Schopenhauer to claim that paradigmatic suicidal agents ultimately desire the opposite of what suicide accomplishes. I conclude by showing how the resulting account of futility can buttress the charge of foolishness as well. My interpretation still leaves Schopenhauer vulnerable to certain objections, but shows that his account is significantly more defensible than previous commentators have realized. (shrink)

In many diagrams one seems to perceive necessity – one sees not only that something is so, but that it must be so. That conflicts with a certain empiricism largely taken for granted in contemporary philosophy, which believes perception is not capable of such feats. The reason for this belief is often thought well-summarized in Hume's maxim: ‘there are no necessary connections between distinct existences’. It is also thought that even if there were such necessities, perception is too passive or (...) localized a faculty to register them. We defend the perception of necessity against such Humeanism, drawing on examples from mathematics. (shrink)

This chapter analyzes several key themes in Kant’s views about modality. We begin with the pre-critical Only Possible Argument in Support of a Demonstration of the Existence of God, in which Kant distinguishes between formal and material elements of possibility, claims that all possibility requires an actual ground, and argues for the existence of a single necessary being. We then briefly consider how Kant’s views change in his mature period, especially concerning the role of form and thought in defining modality. (...) Kant’s mature views, however, present two difficult interpretive puzzles. The first puzzle concerns whether Kant has a generally reductive view of modality. While Kant’s views on logical modality, the role of actuality in grounding possibility, and the relation of modality to cognition all suggest reduction, we argue that the categorial status of modal concepts and the difficulty in even identifying amodal grounds for modal facts all suggest a non-reductive view. The second puzzle concerns whether Kant accepts modal facts or properties at the noumenal level. While Kant’s appeal to noumenal necessary connections, the contingency of noumenal willing, and the idea of a necessary noumenal being suggest that he endorses noumenal modality, his claims that modal concepts express only relations to the faculty of cognition and his claim that modal concepts arise from our distinctive psychological structures, we argue, suggest that he rejects noumenal modality. We conclude by considering potential solutions to these puzzles. (shrink)

Robert Brandom’s expressivism argues that not all semantic content may be made fully explicit. This view connects in interesting ways with recent movements in philosophy of mathematics and logic (e.g. Brown, Shin, Giaquinto) to take diagrams seriously - as more than a mere “heuristic aid” to proof, but either proofs themselves, or irreducible components of such. However what exactly is a diagram in logic? Does this constitute a semiotic natural kind? The paper will argue that such a natural kind does (...) exist in Charles Peirce’s conception of iconic signs, but that fully understood, logical diagrams involve a structured array of normative reasoning practices, as well as just a “picture on a page”.

When travelling to a new city, we acquire knowledge about its physical terrain, directions, historical facts and aesthetic features. Engaging in tourism practices, such as guided walking tours, provides experiences of a city that are necessarily mediated and partial. This has led scholars in tourism studies, and more recently in philosophy, to question the epistemological value of city tours, critiquingthem as passive, lacking in autonomous agency, and providing misrepresentative experiences of the city. In response, we argue that the mediated and (...) partial knowledge of a city acquired through city tours is not epistemologically disvaluable. Although city tours involve the transmission of testimonial knowledge, this does not necessarily render tourists as passive and non-autonomous. Instead,tourists have the potential to participate in the generation of their knowledge actively. Moreover, we argue that city tours also provide a tourist with valuable ‘objectual’ knowledge of a city, whichhas the potential to be first-personal and active, and does not necessarily misrepresent the city’s identity. This type of knowledge is valuable both for tourists as credible epistemic agents, and for the city itself, as the knowledge generated by the tour can facilitate an accurate representation of the city and promote social transformation. We conclude by highlighting four further epistemic and ethical implications of our argument. (shrink)

This piece explores the meaning of the following quote from Charles Peirce (1902), ". . . the main reason logic is unsettled is that thirteen different opinions are current as to the true aim of the science. Now this is not a logical difficulty, but an ethical difficulty; for ethics is the science of aims. Secondly, it is true that ethics has been, and always must be, a theatre of discussion for the reason that its study consists in the gradual (...) development of a distinct recognition of a satisfactory aim. It is a science of subtleties, no doubt; but it is not logic, but the development of the ideal, which really creates and resolves the problems of ethics.". (shrink)

Necessity is a touchstone issue in the thought of Charles Peirce, not least because his pragmatist account of meaning relies upon modal terms. We here offer an overview of Peirce’s highly original and multi-faceted take on the matter. We begin by considering how a self-avowed pragmatist and fallibilist can even talk about necessary truth. We then outline the source of Peirce’s theory of representation in his three categories of Firstness, Secondness and Thirdness, (monadic, dyadic and triadic relations). These have modal (...) purport insofar as the first category corresponds to possibility, the second to mechanical necessity and the third to a kind of semantic or intentional necessity. We then turn to Peirce’s explicit modal epistemology and show how it began as information-relative, with different modalities (e.g. logical, physical, practical) distinguished in terms of respective ‘designated states of information’, and shifted later in his life towards a more robust realism founded in direct perception of ideas in their relations. We then turn to Peirce’s formal logic, focusing on his diagrammatic system of Existential Graphs where he did his most serious logical research. Finally we discuss Peirce’s modal metaphysics and its implications for determinism and realism about universals. (shrink)

A conspicuous feature of contemporary modelling practices is the use of the same mathematical forms and modelling methods across different scientific domains. This model transfer raises many philosophical questions concerning, for example, the exact object of transfer, the relationship between the model and the target domain, the specific challenges such transfer confronts, and the ways in which model transfer relates to scientific progress. While the interest in studying model transfer has increased among philosophers of science in recent years, the phenomenon (...) has not yet received its due attention. The literature is scattered and much of it has addressed questions around the factors that might explain model transfer, such as whether the different target phenomena to which a model is applied eventually prove to be structurally and dynamically similar, or whether they have to share more fundamental ontological features that explain the interdisciplinary success of distinct models. This chapter surveys the existing literature on model transfer with the main goal of highlighting the main findings of existing discussions and pointing out open issues whose discussion would improve our understanding of this highly relevant phenomenon in science.

In this paper, I argue that Plato's views on Forms play a central role in his educational philosophy. In response to what certain commentators have recently written, I contend that this interpretation not only is accurate but also is advantageous because of how it can help philosophy of education. I also address the view, proposed by one philosopher of education, that Plato believes that the most valuable sort of knowledge cannot be fully expressed in words and that the objects of (...) this knowledge are something other than transcendent Forms. Preferable to that view, I argue, is the idea that Plato wants knowledge of Forms which is nonrepresentational. (shrink)

Whereas Charles Peirce’s pragmatist account of truth has been much discussed, his theory of perception still offers a rich mine of insights. Peirce presented a ‘two-ply’ view of perception, which combines an entirely precognitive ‘percept’ with a ‘perceptual judgment’ that is located in the space of reasons. Having previously argued that Peirce outdoes Robert Brandom in achieving a hyper-inferentialism (“Making it Explicit and Clear”, APQ, 2008), I now wish to examine his philosophy in the light of inferentialism’s ‘original fount’ – (...) Wilfrid Sellars. Does Peirce’s percept commit him to the Myth of the Given? I argue that it does not, because although the percept is understood as nonepistemic, it is not understood to justify the perceptual judgment. Rather, the perceptual judgement indexes the percept. I explain this original view, then argue that Peirce and Sellars actually have a great deal in common in their rare diachronically mediated yet at the same time direct perceptual realism, and the ‘critical commonsensist’ epistemology to which it gives rise.

In economics, thought experiments are frequently justified by the difficulty of conducting controlled experiments. They serve several functions, such as establishing causal facts, isolating tendencies, and allowing inferences from models to reality. In this paper, I argue that thought experiments served a further function in economics: facilitating the quantitative definition and measurement of the theoretical concept of utility, thereby bridging the gap between theory and statistical data. I support my argument by a case study, the “hypothetical experiments” of the Norwegian (...) economist Ragnar Frisch (1895-1973). Frisch aimed to eliminate introspection and a subjective concept of utility from economic reasoning. At the same time, he sought behavioral foundations for economic theory that enabled quantitative reasoning. By using thought experiments to justify his set of choice axioms and facilitating the operationalization of utility, Frisch circumvented the problem of observing utility via actual experiments without eliminating the concept of utility from economic theory altogether. As such, these experiments helped Frisch to empirically support the theory’s most important results, such as the laws of demand and supply, without the input of new empirical findings. I suggest that Frisch’s experiments fulfill the main characteristics of thought experiments. (shrink)

“Proof of concept” is a phrase frequently used in descriptions of research sought in program announcements, in experimental studies, and in the marketing of new technologies. It is often coupled with either a short definition or none at all, its meaning assumed to be fully understood. This is problematic. As a phrase with potential implications for research and technology, its assumed meaning requires some analysis to avoid it becoming a descriptive category that refers to all things scientifically exciting. I provide (...) a short analysis of proof of concept research and offer an example of it within synthetic biology. I suggest that not only are there activities that circumscribe new epistemological categories but there are also associated normative ethical categories or principles linked to the research. I examine these and provide an outline for an alternative ethical account to describe these activities that I refer to as “extended agency ethics”. This view is used to explain how the type of research described as proof of concept also provides an attendant proof of principle that is the result of decision-making that extends across practitioners, their tools, techniques, and the problem solving activities of other research groups.

Along with fresh interpretations of Plato, this book proposes a radically new approach to reading him, one that can teach us about protreptic, as it is called, by reimagining the ways in which Socrates engages in it. Protreptic, as it is conceived in the book, is an attempt to bring about a fundamental change of heart in people so that they want truth more than anything else. In taking the approach developed in this book, one doesn't try to get Plato (...) right but simply uses his dialogues as a theoretical tool for gaining insight into protreptic. The book argues that by analyzing Socrates' behavior in the right way, one can better understand how to foster thoughtfulness nowadays, and there is a need to foster it, in part since the health of democracy is at stake.

I argue that Spinoza is more of a moral realist than an anti-realist. More specifically, I argue that Spinoza is more of a realist than Kant, and that his view has deep similarities with Plato's metaethics. Along the way, I identify three approaches to the moral realism/anti-realism distinction. Classifying Spinoza as a moral realist brings out a number of important complexities that have been overlooked by many of Spinoza's readers and by many contemporary metaethicists.
