When do probability distribution functions (PDFs) about future climate misrepresent uncertainty? How can we recognise when such misrepresentation occurs and thus avoid it in reasoning about or communicating our uncertainty? And when we should not use a PDF, what should we do instead? In this paper we address these three questions. We start by providing a classification of types of uncertainty and using this classification to illustrate when PDFs misrepresent our uncertainty in a way that may adversely affect decisions. We (...) then discuss when it is reasonable and appropriate to use a PDF to reason about or communicate uncertainty about climate. We consider two perspectives on this issue. On one, which we argue is preferable, available theory and evidence in climate science basically excludes using PDFs to represent our uncertainty. On the other, PDFs can legitimately be provided when resting on appropriate expert judgement and recognition of associated risks. Once we have specified the border between appropriate and inappropriate uses of PDFs, we explore alternatives to their use. We briefly describe two formal alternatives, namely imprecise probabilities and possibilistic distribution functions, as well as informal possibilistic alternatives. We suggest that the possibilistic alternatives are preferable. -/- . (shrink)

The temporal unity of the self cannot be accounted for by the continuity of causal, factual, or contiguous relations between independently definable mental events, as proposed by Locke and Parfit. The identity of the self over time is normative: it depends on the institutional context of social rules external to the self that determine the relationship between past commitments and current responsibilities. (2005).

Four philosophers, Husserl, Wittgenstein, Dennett, and Hegel, who hold for the most part radically different philosophies, all agree on rejecting the notion of atomic entities, of “things-in-themselves,” and insist that objects only make sense – can only be what they are -- in a context.

Tomasello offers an evolutionary, palaeoanthropological account of the human origin of objects and objectivity. Husserl gives a phenomenological account of the constitution of objects by intersubjectivity. Comparing the two, I claim that Tomasello’s “naturalized” approach closely parallels Husserl’s transcendental approach.

Modern selfhood presents itself as autonomous, overcoming emotion by following cognitive, moral and linguistic norms on the basis of clear, rational principles. It is difficult to imagine how such normative creatures could have evolved from their purely biological, non-normative, primate ancestors. I offer a just-so story to make it easier to imagine this transition. Early hominins learned to cooperate by developing group identities based on tribal norms. Group identity constituted proto-selves as normative creatures. Such group identity was not based on (...) autonomous selfhood – such an explanation would be anachronistic -- but on emotional patterning. By imitation, music, dance, ritual and other emotional practices, proto-selves learned how to bind themselves to the norms of their culture. Such conformity was a transitional evolutionary stage between primates and selves. Emotion and rationality are not incompatible: even contemporary selfhood remains rooted in emotional identity.

Language defines human existence. Yet defining language is a fraught project. I use the term "language" to refer to a specific mode of information transfer. First, it is a communicative mode. By communication I mean the information transfer serves a function, that is, an activity that occurs because it has increased the evolutionary fitness of ancestors. Secondly, while all communication is governed by norms, human communication, as opposed to biological communication, is governed by norms that have evolved within the learned (...) traditions of individual cultures. The meaning of an assertion in a culture’s language is the set of commitments to which that culture holds its speakers when they utter that assertion. Syntax has appeared in recent evolution to facilitate and enrich the communicative function, but it is a secondary aspect of language. The defining characteristic of human communication, of "language," -- is its capacity to constitute meaning. (shrink)

Against the concept that objects are defined by their self-contained essence – “thing-in-themselves” – Husserl and Foucault claim they are defined by intersubjectivity or social institutions. I argue that biological and even physical (complex) systems can constitute the unity and meaning of objects.

Why should anyone be bound by cognitive norms, such as the norms of reason or mathematics? To become a mathematician is to learn to obey the norms of the mathematical community. A self becomes intentional by binding itself to communal norms. Only then can it have the freedom to think or make assertions about the community’s objects -- triangles or imaginary numbers, for example. Norms do not bind selves from the outside: being bound by norms is what constitutes a self.

The self is not a metaphysical object but a mode of temporal organization unified by responsibility. Learning to be responsible constitutes the self as a self-identical entity over time. Responsibility depends on the current self interpreting previous events, attributing them to itself and thereby committing itself for the future. (2004) .

Biological organisms, languages and selves are normative entities, so must be understood in terms of norms. Mechanistic understanding is based on causal necessity, but normative understanding relies on a grasp of the contingencies of evolution, history and personal experience.

A self is a temporal unity in which responsibility for past commitments modifies how the present world is experienced and evaluated. This structure is analogous (a) to biological evolutionary changes in perception and (b) to how changes in a computer program determine how it will respond in the future. Responsibility is not an add-on to a self, but the mode of its integration over time. (Presented at Royal Institute of Philosophy Annual Conference, Narrative and Understanding Persons, University of Hertfordshire, UK, (...) 2005). (shrink)

Thought is not based on an image that is isomorphic to the object. Descartes, Husserl, Frege, Wittgenstein and Brandom progressively overcome this Aristotelian misconception of the intentionality of thinking.

The received Cognitive Science paradigm holds that the brain manipulates mental representations of reality. This position is problematic. My alternative to representationalism is that each organism lives in its own "world" made up of objects defined by reference to the organism’s perceptual systems. These objects act as supervenient causes on organisms without the mediation of mental representations. (1992).

Kosgaard claims that selves/agents self-constitute during actions by relying on principles such as Kant’s Categorical Imperative. This intellectualist approach neglects the body. Merleau-Ponty considers the “lived body” and its perceptual world as the source of the unity of action, an approach that I extrapolate to all biological organisms.

The sameness and difference of entities depend on context or horizon and these horizons may be either synchronous or diachronic. Money and qualia are examples of identity within synchronic contexts. Music, biological functions, and cultural roles are defined by their diachronic horizons. The diachronic cultural and narrative contexts of selves are what makes them distinctively different.

Explanation is a human activity. Teleological, causal, and evolutionary explanations are all valid forms of responding to particular puzzlements. Reductionism incorrectly assumes there is one absolute explanation. While causal explanation appeals primarily to necessity, evolutionary explanation is based largely on contingency.

What makes us persons? Is it our bodies, our minds, or our consciousness? For centuries, philosophers have sought to answer these questions. While some believe humans are physical or biological, others claim we have an immaterial soul. This book proposes a new alternative. Selves were formed in evolution through connections and commitments to others when early hominins lived in tribal groups and developed languages. As humans learned to fulfill these commitments, they not only cultivated relationships but also created their personal (...) identities. Their habits of responsibility established their characters and therefore their reputations within their communities. This naturalistic approach proposes that a self is defined by the history of its commitments to cultural and personal norms. While brain processes are required, the self is not some internal, private mind but primarily a role within its community. As technology advances, selfhood could in the future be enabled by electronic, quantum, or other non-biological means. So if a self is formed through norms, could artificial intelligence evolve to have self-identity? (shrink)

Methodological and philosophical foundations in the anthropology of Ruth Benedict and Margaret Mead.

Jacobs, in Choosing Character, seems to assume that there are selves already capable of voluntary choice who then choose their character by developing habits. I argue that selves, choice, responsibility and character form a conceptual and practical hermeneutic circle, a whole without which selfhood makes no sense. There can be no selfhood prior to responsible character.

Introduzione Lo studio delle emozioni è stato caratterizzato per molti anni da una netta separazione fra mente e corpo. Negli anni Sessanta e Settanta – l’epoca aurea del cognitivismo – le teorie delle emozioni si occupavano soprattutto degli antecedenti cognitivi dell’emozione, le cosiddette “valutazioni”. I processi corporei erano visti essenzialmente come sottoprodotti della cognizione, e come troppo poco specifici per poter contribuire alla varietà dell’esperienza emotiva. La cognizione e...

Sharon Street’s 2006 article “A Darwinian Dilemma for Realist Theories of Value” challenges the epistemological pretensions of the moral realist, of the nonnaturalist in particular. Given that “Evolutionary forces have played a tremendous role in shaping the content of human evaluative attitudes” – why should one suppose such attitudes and concomitant beliefs would track an independent moral reality? Especially since, on a nonnaturalist view, moral truth is causally inert. I abstract a logical skeleton of Street’s argument and, with its (...) aid, focus on problematic assumptions regarding the (a)causality of moral truth. It emerges that there are acquired causal powers that compensate for the intrinsic impotence of moral truth, as well as two distinct levels at which truth-tracking might occur. I argue that while evolution’s selective forces do not track moral truth, that does not imply individual organisms could not have evolved that capability. -/- . (shrink)

In this article, I discuss a trivialization worry for Hartry Field’s official formulation of the access problem for mathematical realists, which was pointed out by Øystein Linnebo. I argue that various attempted reformulations of the Benacerraf problem fail to block trivialization, but that access worriers can better defend themselves by sticking closer to Hartry Field’s initial informal characterization of the access problem in terms of general epistemic norms of coincidence avoidance.

In this paper, I will attempt to develop and defend a common form of intuitive resistance to the companions in guilt argument. I will argue that one can reasonably believe there are promising solutions to the access problem for mathematical realism that don’t translate to moral realism. In particular, I will suggest that the structuralist project of accounting for mathematical knowledge in terms of some form of logical knowledge offers significant hope of success while no analogous approach offers such hope (...) for moral realism.

It is commonly assumed that grounding relations are asymmetric. Here I develop and argue for a theory of metaphysical structure that takes grounding to be nonsymmetric rather than asymmetric. Even without infinite descending chains of dependence, it might be that every entity is grounded in some other entity. Having first addressed an immediate objection to the position under discussion, I introduce two examples of symmetric grounding. I give three arguments for the view that grounding is nonsymmetric (I call this view (...) ‘metaphysical interdependence’). These arguments are: (i) that metaphysical interdependence is the only theory able to reconcile competing intuitions about grounding; (ii) that it is the only theory consistent with both ‘gunk’ and ‘junk’; and (iii) that offers a satisfactory solution to the problem concerning whether or not grounding is itself grounded. (shrink)

Attempts to elucidate grounding are often made by connecting grounding to metaphysical explanation, but the notion of metaphysical explanation is itself opaque, and has received little attention in the literature. We can appeal to theories of explanation in the philosophy of science to give us a characterization of metaphysical explanation, but this reveals a tension between three theses: that grounding relations are objective and mind-independent; that there are pragmatic elements to metaphysical explanation; and that grounding and metaphysical explanation share a (...) close connection. Holding fixed the mind-independence of grounding, I show that neither horn of the resultant dilemma can be blunted. Consequently, we should reject the assumption that grounding relations are mind-independent. (shrink)

It's currently fashionable to take Putnamian model theoretic worries seriously for mathematics, but not for discussions of ordinary physical objects and the sciences. But I will argue that (under certain mild assumptions) merely securing determinate reference to physical possibility suffices to rule out nonstandard models of our talk of numbers. So anyone who accepts realist reference to physical possibility should not reject reference to the standard model of the natural numbers on Putnamian model theoretic grounds.

Since Benacerraf’s ‘What Numbers Could Not Be, ’ there has been a growing interest in mathematical structuralism. An influential form of mathematical structuralism, modal structuralism, uses logical possibility and second order logic to provide paraphrases of mathematical statements which don’t quantify over mathematical objects. These modal structuralist paraphrases are a useful tool for nominalists and realists alike. But their use of second order logic and quantification into the logical possibility operator raises concerns. In this paper, I show that the work (...) of both these elements can be done by a single natural generalization of the logical possibility operator. (shrink)

This paper is a defense of moral evidentialism, the view that we have a moral obligation to form the doxastic attitude that is best supported by our evidence. I will argue that two popular arguments against moral evidentialism are weak. I will also argue that our commitments to the moral evaluation of actions require us to take doxastic obligations seriously.

In this paper I will draw attention to an important route to external world skepticism, which I will call confidence skepticism. I will argue that we can defang confidence skepticism (though not a meeker ‘argument from might’ which has got some attention in the 20th century literature on external world skepticism) by adopting a partially psychologistic answer to the problem of priors. And I will argue that certain recent work in the epistemology of mathematics and logic provides independent support for (...) such psychologism. (shrink)

Mathematical knowledge and moral knowledge (or normative knowledge more generally) can seem intuitively puzzling in similar ways. For example, taking apparent human knowledge of either domain at face value can seem to require accepting that we benefited from some massive and mysterious coincidence. In the mathematical case, a pluralist partial response to access worries has been widely popular. In this paper, I will develop and address a worry, suggested by some works in the recent literature like (Clarke-Doane, 2020), that connections (...) between ought facts and action prevent us from giving a similarly pluralist response to moral access worries. (shrink)

Most contemporary political science researchers are advocates of multimethod research, however, the value and proper role of qualitative methodologies, like case study analysis, is disputed. A pluralistic philosophy of science can shed light on this debate. Methodological pluralism is indeed valuable, but does not entail causal pluralism. Pluralism about the goals of science is relevant to the debate and suggests a focus on the difference between evidence for warrant and evidence for use. I propose that case study research provides evidence (...) for use through providing information that bears on the applicability of causal generalizations and risk assessment. (shrink)

The perfectly natural properties and relations are special—they are all and only those that "carve nature at its joints." They act as reference magnets, form a minimal supervenience base, figure in fundamental physics and in the laws of nature, and never divide duplicates within or between worlds. If the perfectly natural properties are the (metaphysically) important ones, we should expect being a perfectly natural property to itself be one of the (perfectly) natural properties. This paper argues that being a perfectly (...) natural property is not a very natural property, and examines the consequences. (shrink)

It’s sometimes suggested that we can (in a sense) settle the truth-value of some statements in the language of number theory by stipulation, adopting either φ or ¬φ as an additional axiom. For example, in Clarke-Doane (2020b) and a series of recent APA presentations, Clarke-Doane suggests that any Σ01 sound expansion of our current arithmetical practice would express a truth. In this paper, I’ll argue that (given a certain popular assumption about the model-theoretic representability of languages like ours) we can’t (...) know ourselves to have any such freedom. (shrink)

To address the underrepresentation of women in philosophy effectively, we must understand the causes of the early loss of women. In this paper we challenge one of the few explanations that has focused on why women might leave philosophy at early stages. Wesley Buckwalter and Stephen Stich offer some evidence that women have different intuitions than men about philosophical thought experiments. We present some concerns about their evidence and we discuss our own study, in which we attempted to replicate their (...) results for 23 different responses to 14 scenarios . We also conducted a literature search to see if other philosophers or psychologists have tested for gender differences in philosophical intuitions. Based on our findings, we argue that that it is unlikely that gender differences in intuitions play a significant role in driving women from philosophy. (shrink)

In this article, we reflect on our experiences teaching a PWOL course called Philosophy for Living. The course uses modules focused on different historical philosophical ways of life (Epicureanism, Stoicism, Confucianism, Existentialism, etc.) to engage students in exploring how philosophy can be a way of life and how its methods, virtues, and ideas can improve their own lives. We describe and compare our experiences with two central aspects of our approach: engagement with diversity and the use of immersive experiences and (...) assignments. In particular, we discuss how we recognize and center various forms of diversity in philosophy—cultural and gender diversity, but also diversity in how and in what forms philosophy can be done and what “philosophy as a way of life” can be. We also examine how the experimental and experiential aspects of immersive assignments promote deeper understanding and create possibilities for personal transformation. (shrink)

The paper argues that knowledge is not closed under logical inference. The argument proceeds from the openness of evidential support and the dependence of empirical knowledge on evidence, to the conclusion that knowledge is open. Without attempting to provide a full-fledged theory of evidence, we show that on the modest assumption that evidence cannot support both a proposition and its negation, or, alternatively, that information that reduces the probability of a proposition cannot constitute evidence for its truth, the relation of (...) evidential support is not closed under known entailment. Therefore the evidence-for relation is deductively open regardless of whether evidence is probabilistic or not. Given even a weak dependence of empirical knowledge on evidence, we argue that empirical knowledge is also open. On this basis, we also respond to the strongest argument in support of knowledge closure. Finally, we present a number of significant benefits of our position, namely, offering a unified explanation for a range of epistemological puzzles. (shrink)

I argue that current discussions of the epistemological significance of reflection have entangled concerns about reflection with agential concerns. I begin by showing that a central strand of internalist criticism finds externalism unsatisfactory because it fails to provide a particular kind of self-knowledge, knowledge about the epistemic status of one’s own beliefs. Identifying this internalist motivation as the desire for a kind of self-knowledge opens up new possibilities and suggests new conceptual resources. I employ one of these resources—Richard Moran’s distinction (...) between the theoretical stance and the deliberative stance—to locate two types of reflection: mere reflective awareness of one’s attitudes and agent-awareness of one’s attitudes. I then examine Ernest Sosa’s account of the importance of reflection, showing how Moran’s distinction brings out the centrality of agential concerns in Sosa’s argument for reflective knowledge. I also consider briefly its relevance to fully apt knowledge. While I focus on Sosa’s epistemology, the point extends to internalism more generally. (shrink)

The idea that knowledge can be extended by inference from what is known seems highly plausible. Yet, as shown by familiar preface paradox and lottery-type cases, the possibility of aggregating uncertainty casts doubt on its tenability. We show that these considerations go much further than previously recognized and significantly restrict the kinds of closure ordinary theories of knowledge can endorse. Meeting the challenge of uncertainty aggregation requires either the restriction of knowledge-extending inferences to single premises, or eliminating epistemic uncertainty in (...) known premises. The first strategy, while effective, retains little of the original idea—conclusions even of modus ponens inferences from known premises are not always known. We then look at the second strategy, inspecting the most elaborate and promising attempt to secure the epistemic role of basic inferences, namely Timothy Williamson’s safety theory of knowledge. We argue that while it indeed has the merit of allowing basic inferences such as modus ponens to extend knowledge, Williamson’s theory faces formidable difficulties. These difficulties, moreover, arise from the very feature responsible for its virtue- the infallibilism of knowledge. (shrink)

This note points out a conflict between some common intuitions about metaphysical possibility. On the one hand, it is appealing to deny that there are robust counterfactuals about how various physically impossible substances would interact with the matter that exists at our world. On the other hand, our intuitions about how concepts like MOUNTAIN apply at other metaphysically possible worlds seem to presuppose facts about ‘solidity’ which cash out in terms of these counterfactuals. I consider several simple attempts to resolve (...) this conflict and note they all fall short. (shrink)

For many years emotion theory has been characterized by a dichotomy between the head and the body. In the golden years of cognitivism, during the nineteen-sixties and seventies, emotion theory focused on the cognitive antecedents of emotion, the so-called “appraisal processes.” Bodily events were seen largely as byproducts of cognition, and as too unspecific to contribute to the variety of emotion experience. Cognition was conceptualized as an abstract, intellectual, “heady” process separate from bodily events. Although current emotion theory has moved (...) beyond this disembodied stance by conceiving of emotions as involving both cognitive processes (perception, attention, and evaluation) and bodily events (arousal, behavior, and facial expressions), the legacy of cognitivism persists in the tendency to treat cognitive and bodily events as separate constituents of emotion. Thus the cognitive aspects of emotion are supposedly distinct and separate from the bodily ones. This separation indicates that cognitivism’s disembodied conception of cognition continues to shape the way emotion theorists conceptualize emotion. (shrink)

Buddhism originated and developed in an Indian cultural context that featured many first-person practices for producing and exploring states of consciousness through the systematic training of attention. In contrast, the dominant methods of investigating the mind in Western cognitive science have emphasized third-person observation of the brain and behavior. In this chapter, we explore how these two different projects might prove mutually beneficial. We lay the groundwork for a cross-cultural cognitive science by using one traditional Buddhist model of the mind (...) – that of the five aggregates – as a lens for examining contemporary cognitive science conceptions of consciousness.

Natural experiments are an increasingly popular research design in political science. This popularity raises a number of questions. First, what are natural experiments and why are they appealing? Second, what makes a good natural experiment? And finally, are natural experiments able to provide resources for knowledge production that other methodologies cannot or do not provide? Using Mary Morgan’s and Thad Dunning’s recent work on natural experiments, I offer answers to the first two questions and use the analysis to argue that (...) natural experiments highlight features of knowledge production that support methodological pluralism and the multiple aims of research.

Harman and Lewis credit Kripke with having formulated a puzzle that seems to show that knowledge entails dogmatism. The puzzle is widely regarded as having been solved. In this paper we argue that this standard solution, in its various versions, addresses only a limited aspect of the puzzle and holds no promise of fully resolving it. Analyzing this failure and the proper rendering of the puzzle, it is suggested that it poses a significant challenge for the defense of epistemic closure.

Abstract In his discourses on ‘the lily of the field and the bird of the air,’ Kierkegaard presents faith as the best possible response to our precarious and uncertain condition, and as the ideal way to cope with the insecurities and concerns that his readers will recognize as common features of human existence. Reading these discourses together, we are introduced to the portrait of a potential believer who, like the ‘divinely appointed teachers’—the lily and the bird—succeeds in leading a life (...) that is full of care, but free of worry. Such a portrait, we claim, echoes Kierkegaard’s portrait of the knight of faith in Fear and Trembling . In this essay we suggest that faith, as characterized in the ‘lily and bird’ discourses, is a kind of existential trust that would allow us to overcome worry, while remaining wholeheartedly engaged in the finite realm of our cares and concerns. We claim that Kierkegaard’s goal in these discourses is not to belittle our earthly cares, but to invite us to develop a modified attitude toward all that we are susceptible to worry about.

There are few indulgences academics can crave more than to have their work considered and addressed by leading researchers in their field. We have been fortunate to have two outstanding philosophers from whose work we have learned a great deal give ours their thoughtful attention. Grappling with Stephen Yablo’s, and Juan Comesaña’s comments and criticisms has helped us gain a better understanding of our ideas as well as their shortcomings. We are extremely grateful to them for the attentiveness and seriousness (...) with which they have considered our arguments and to philosophical studies for giving us this opportunity. Given the substantive difference between the two response papers, there is not much beyond sincere gratitude that we can covey to them jointly. We will therefore address them in turn. (shrink)
