In contemporary philosophy, various attempts have been made in relation to placing our minds or mental states in the natural world or nature. In this context, there is a clear divide between naturalism and anti-naturalism, materialism and immaterialism, etc. Driven by the influence of naturalistic turn in philosophy and scientism, many philosophers have tried to put forth various naturalistic accounts of the relationship between mind and natural world. However, many of these accounts are naturalistic based on the modern scientific conception (...) of nature which has been hailed as the dominating conception of nature. John McDowell in his magnum opus Mind and World, while criticizing modern scientific account of the relationship between mind and world, has not resorted back to anti-naturalism. Instead, he has tried to give us certain clues to develop an account of an alternative form of naturalism which is at the same time radically different from both scientific naturalism and mysterious anti-naturalism. In this paper, I will try to search for an alternative naturalism following McDowell and examine to what extent this account is tenable. In this context, we shall discuss various approaches to understand the relation between reason/normativity (which is one of the significant constituting elements of our mind) and natural world.

Recent years have seen an explosion of empirical data concerning arithmetical cognition. In this paper that data is taken to be philosophically important and an outline for an empirically feasible epistemological theory of arithmetic is presented. The epistemological theory is based on the empirically well-supported hypothesis that our arithmetical ability is built on a protoarithmetical ability to categorize observations in terms of quantities that we have already as infants and share with many nonhuman animals. It is argued here that arithmetical (...) knowledge developed in such a way cannot be totally conceptual in the sense relevant to the philosophy of arithmetic, but neither can arithmetic understood to be empirical. Rather, we need to develop a contextual a priori notion of arithmetical knowledge that preserves the special mathematical characteristics without ignoring the roots of arithmetical cognition. Such a contextual a priori theory is shown not to require any ontologically problematic assumptions, in addition to fitting well within a standard framework of general epistemology. (shrink)

The paper offers some observations with a view to correcting ostensible misunderstandings of the so-called New Natural Law (“NNL”) theory, concluding that the NNL theory is unworkable and unsustainable, even on its own terms. It is argued that the NNL theory is based on fundamental misunderstandings of the nature of necessity in Aquinas; the nature of propositions which are “known in themselves” (per se nota); and the nature of fundamental practical reasoning. It is argued that, where the NNL theory differs (...) from that of Aquinas, the latter provides a better framework for the development of accounts of natural law today. (shrink)

It is often assumed that there is a close connection between Quine's criticism of the analytic/synthetic distinction, in 'Two dogmas of empiricism' and onwards, and his thesis of the indeterminacy of translation, in Word and Object and onwards. Often, the claim that the distinction is unsound (in some way or other) is taken to follow from the indeterminacy thesis, and sometimes the indeterminacy thesis is supported by such a claim. However, a careful scrutiny of the indeterminacy thesis as stated by (...) Quine, and the varieties of the analytic/synthetic distinction, reveals that the two claims are mutually independent. Neither does the claim that the distinction is unsound follow from the indeterminacy thesis, nor that thesis from unsoundness claim, under any of the common interpretations of the analytic/synthetic distinction.

In Our Knowledge of the Internal World, Robert Stalnaker describes two opposed perspectives on the relation between the internal and the external. According to one, the internal world is taken as given and the external world as problematic, and according to the other, the external world is taken as given and the internal world as problematic. Analytic philosophy moved from the former to the latter, from problems of world-construction to problems of self-locating beliefs. I argue in this paper that these (...) problems are equivalent: both arise because experience and objective, external facts jointly underdetermine their relation. Both can be seen as a problem of expressive completeness; of the internal language in the former case, and of the non-indexical language in the second. (shrink)

This highly multidisciplinary collection discusses an increasingly important topic among scholars in science and technology studies: objectivity in science. It features eleven essays on scientific objectivity from a variety of perspectives, including philosophy of science, history of science, and feminist philosophy. Topics addressed in the book include the nature and value of scientific objectivity, the history of objectivity, and objectivity in scientific journals and communities. Taken individually, the essays supply new methodological tools for theorizing what is valuable in the pursuit (...) of objective knowledge and for investigating its history. The essays offer many starting points, while suggesting new avenues of research. Taken collectively, the essays exemplify the very virtues of objectivity that they theorize—in reading them together, the reader can sense various anxieties about the dangerously subjective in our age and locate commonalities of concern as well as differences of approach. As a result, the volume offers an expansive vision of a research community seeking a communal understanding of its own methods and its own epistemic anxieties, struggling to enunciate the key problems of knowledge of our time and offer insight into how to overcome them. -/- (Contributors: Alex Csiszar, Scott Edgar, Peter Galison, Ian Hacking, Sandra Harding, Moira Howes, Paolo Savoia, Judy Segal, Joan Steigerwald, and Alison Wylie).

Despite the conclusions from the contemporary philosophy of science, many economists cherish the ideal of positive science. Therefore, value-free economics is still the central paradigm in economics. The first aim of the paper is to investigate economics' axiomatic assumptions from an epistemological perspective. The critical analysis of the literature shows that the positive-normative dichotomy is exaggerated. Moreover, value-free economics is based on normative foundations that have a negative impact on individuals and society. The paper's second aim is to show that (...) economics' normativity is not a problem because the discussion concerning values is possible and unavoidable. In this context, Weber and other methodologists are investigated. The conclusion of the paper is that science can thrive without strict methodological rules thanks to institutional mechanisms. Therefore, economists could learn from artists who accept the world without absolute rules. This perspective opens the possibility for methodological pluralism and normative approaches. (shrink)

Climate change mitigation has become a paradigm case both for externalities in general and for the game-theoretic model of the Tragedy of the Commons (ToC) in particular. This situation is worrying, as we have reasons to suspect that some models in the social sciences are apt to be performative to the extent that they can become self-fulfilling prophecies. Framing climate change mitigation as a hardly solvable coordination problem may force us into a worse situation, by changing real-world behaviour to fit (...) our model, rather than the other way around. But while this problem of the performativity of the ToC has been noted in a recent paper in this journal by Matthew Kopec, his proposed strategies for dealing with their self-fulfilling nature fall short of providing an adequate solution. Instead of relying on the idea that modelling assumptions are always strictly speaking false, this paper shows that the problem may be better framed as a problem of underdetermination between competing explanations. Our goal here is to provide a framework for choosing between this set of competing models that allows us to avoid a ‘Russian Roulette’-like situation in which we gamble with existential risk.

The topic of the presence, legitimacy and epistemic worth of narrative explanations in different kinds of scientific discourse has already enjoyed several revivals within related discussions in contemporary philosophy of science. In fact, we have recently witnessed a more extensive, more unprejudiced and ambitious attention to narrative modes of making science. I think we need a systematic theoretical framework in order to categorize these different functions of narratives and understand their role in scientific explanatory and justificatory practice. My claim is (...) that some distinctions and analytic tools developed within the field of contemporary Argumentation Theory might be of help. (shrink)

This paper canvasses the various dimensions along which theories of truth may disagree about the extent to which truth is minimal.

At the onset of quantum mechanics, it was argued that the new theory would entail a rejection of classical logic. The main arguments to support this claim come from the non-commutativity of quantum observables, which allegedly would generate a non-distributive lattice of propositions, and from quantum superpositions, which would entail new rules for quantum disjunctions. While the quantum logic program is not as popular as it once was, a crucial question remains unsettled: what is the relationship between the logical structures (...) of classical and quantum mechanics? In this essay we answer this question by showing that the original arguments promoting quantum logic contain serious flaws, and that quantum theory does satisfy the classical distributivity law once the full meaning of quantum propositions is properly taken into account. Moreover, we show that quantum mechanics can generate a distributive lattice of propositions, which, unlike the one of quantum logic, includes statements about expectation values which are of undoubtable physical interest. Lastly, we show that the lattice of statistical propositions in classical mechanics follows the same structure, yielding an analogue non-commutative sublattice of classical propositions. This fact entails that the purported difference between classical and quantum logic stems from a misconstructed parallel between the two theories. (shrink)

Decision-making procedures in medical practice are often analysed by both philosophers of science and ethicists, as well as statisticians, clinicians and methodologists. The paper focuses on decisions made by patients in situations of moral dilemma. The main purpose is to analyse the strategies used in resolving such dilemmas. First, the concept of a ‘situation of moral dilemma’ is clarified. Then, two types of strategies for resolving such situations are distinguished. The first strategy requires revising the patient’s belief system or moral (...) orientation. The second one includes a group of non-revision beliefs strategies (NRB). The authors argue in support of the thesis that NRB strategies are, in fact, the patient’s first choice when it comes to resolving moral dilemmas. The paper analyses situations where the NRB strategies may prove effective, as well as situations where they fail and where the solution of the moral dilemma must be addressed by revising the accepted belief system. The findings will help to better understand patients’ decision-making processes. (shrink)

Much feminist philosophy of science has been developed as a reaction against logical empiricism and the associated view that social factors play no role in good science. Recent accounts of the Vienna Circle that highlighted the ways in which some of its members attempted to combine their empiricism with emancipatory politics are used here as a basis on which to reassess the relationship between logical empiricism and feminism. The focus is chiefly on Otto Neurath.

Sceptical arguments in epistemology typically employ sceptical hypotheses, which are rivals to our everyday beliefs so constructed that they fit exactly the evidence on which those beliefs are based. There are two ways of using a sceptical hypothesis to undermine an everyday belief, giving rise to two distinct sorts of sceptical argument: underdetermination‐based and closure‐based. However, both sorts of argument, as usually formulated in the literature, fall foul of evidential holism, for they ignore the crucial role of background beliefs. An (...) analogy with the philosophy of science makes this point explicit. There is no simple way to “holism proof” the two sceptical arguments. (shrink)

According to Paul Boghossian, some truths are knowable a priori because they are expressed by epistemically analytic sentences. In such cases, understanding the sentence is meant to suffice for justified belief in the proposition it expresses. One alleged route from understanding to justification goes via what Boghossian calls ‘the synonymy model’. This article presents a dilemma for this model and argues that although a strategy for avoiding the dilemma is available, this does not vindicate Boghossian's model.

This essay presents a long, detailed, in many ways critical but also appreciative account, of David Bloor’s recent book The Enigma of the Aerofoil. I take that work as the crowning statement of ideas and principles developed over the past four decades by Bloor and other exponents of the ‘strong programme’ in the sociology of scientific knowledge. It therefore offers both a test-case of that approach and a welcome opportunity to review, clarify and extend some of the arguments brought against (...) it by critical realists. This purpose is particularly well served by Bloor’s having here assembled such a wealth of scientific, historical, political and socio-cultural data concerning one specific, very crucial period of research into theories of aerodynamic lift. His book thus provides an exceptionally useful point of engagement for anyone seeking to adjudicate these issues from a critically angled but engaged and constructive standpoint. (shrink)

The revelatory paper, “Dilemmas in the General Theory of Planning,” by Rittel and Webber (Policy Sci 4:155–169, 1973 ) has had great impact because it provides one example of an emergent consensus across many disciplines. Many “problems,” as addressed in real-world situations, involve elements that exceed the complexity of any known or hoped-for model, or are “wicked.” Many who encounter this work for the first time find that their concept of wicked problems aptly describes many environmental disputes. For those frustrated (...) with the lack of progress in many areas of environmental protection, Rittel and Webber’s work suggested a powerful explanatory hypothesis: Complex environmental problems cannot be comprehended within any of the accepted disciplinary models available in the academy or in discourses on public interest and policy. What should we conclude about the future of social improvements, and about the possibilities for rational discourse leading to cooperative action, with respect to this huge number of pressing public, environmental problems? Can we find ways to address environmental problems that improves the ability of communities to respond creatively and rationally to them? I will argue that, while the Rittel-Webber critique requires us to abandon many of the assumptions associated with a positivistic view of science and its applications to policy analysis, it also points to a more productive direction for the future of policy analysis. I will introduce “boundary critique,” developed within Critical Systems Theory (CST), an approach that offers some reason for optimism in dealing with some aspects of wickedness. (shrink)

This article examines various dilemmas (or, as I suggest, pseudo-dilemmas) that have dogged epistemology and philosophy of language since the 1940s heyday of logical empiricism. These have to do chiefly with the problem those thinkers faced in overcoming the various dichotomies imposed by their Humean insistence on maintaining a sharp distinction between logical 'truths of reason' and empirical 'matters of fact'. I trace this problem back to Kant's failure to offer any plausible, explanatorily adequate account of the process whereby 'sensuous (...) intuitions' were brought under 'concepts of understanding' through the joint (somewhat mysterious) agency of 'judgement' and 'imagination'. The argument then proceeds, via Quine's (on the face of it) radically anti-dualist critique of logical empiricism, to more recent attempts - by Davidson and McDowell - to locate the residual dualism in Quine (that of scheme and content), and thus to bring philosophy out on the far side of all these vexing dilemmas. I maintain that the problem goes much deeper and re-emerges with full force both in Davidson's coupling of a formalized (Tarskian) truth-theoretic approach with a strain of radical empiricism and likewise in McDowell's revisionist, supposedly 'naturalized', but none the less dualist reading of Kant on the twin powers of 'spontaneity' and 'receptivity'. Its ultimate source - I suggest - is the normative deficit, i.e., the lack of rational and justificatory values that has typified empiricist thinking from Hume to Quine, along with its attendant sceptical outlook as regards the existence of causal powers or the status and validity of causal explanations. My paper concludes by indicating briefly some alternative resources that might point a way beyond this longstanding impasse. (shrink)

This essay responds to Jeff Malpas's foregoing article, itself written in response to my various publications over the past two decades concerning Donald Davidson's ideas about truth, meaning, and interpretation. It has to do mainly with our disagreement as regards the substantive content of Davidson's truth-based semantic approach in relation to the problematic legacy of logical empiricism, including Quine's incisive but no less problematical critique of that legacy. I also raise questions with respect to Malpas's coupling of Davidson with Heidegger, (...) intended to provide a more adequate depth-ontological grounding for the formalized (logico-semantic) conception of truth that Davidson adopts from Tarski. My essay then argues the case for an outlook of objectivist causal realism joined with a theory of inference to the best, most rational explanation that would satisfy this need in more philosophically (as well as scientifically) accountable terms.

This article offers a critical review of various ontological-relativist arguments, mostly deriving from the work of W. V. Quine and Thomas K hn. I maintain that these arguments are (1) internally contradictory, (2) incapable of accounting for our knowledge of the growth of scientific knowledge, and (3) shown up as fallacious from the standpoint of a causal-realist approach to issues of truth, meaning, and interpretation. Moreover, they have often been viewed as lending support to such programmes as the 'strong' sociology (...) of knowledge and the turn towards wholesale cultural-relativist doctrines, whether of the Wittgensteinian ('language-games') or Heideggerian (depth-hermeneutic) varieties. Thus Richard Rorty recommends that we should henceforth drop all that old-fashioned talk of 'truth', 'knowledge', or 'reality', since whatever warrants those descriptions from time to time is just the product of some currently favoured language-game or range of elective metaphors. Such ideas have little in common with Quine's general outlook of robust physicalism, nor again - though the case is less clear - with Kuhn's reconsidered approach to these issues as set forth in his 1969 Postscript to The Structure of Scientific Revolutions . However, both thinkers have left themselves open to misconstrual by adopting a sceptical-relativist fallback position in response to the well-known problems with logical empiricism. This essay therefore reviews those problems with reference to alternative, more adequate accounts of what is involved in the process of scientific discovery and theory-change. (shrink)

Much recent work in neuroscience aims to shed light on whether we have free will. Can it? Can any science? To answer, we need to disentangle different notions of free will, and clarify what we mean by ‘empirical’ and ‘testable’. That done, my main conclusion is, duly interpreted: that free will is not a testable hypothesis. In particular, it is neither verifiable nor falsifiable by empirical evidence. The arguments for this are not a priori but rather are based on a (...) posteriori consideration of the relevant neuroscientific investigations, as well as on standard philosophy of science work on the notion of testability.

Abstract Impossible fictions have lessons to teach us about linguistic representation, about mental content and concepts, and about uses of conceivability in epistemology. An adequate theory of impossible fictions may require theories of meaning that can distinguish between different impossibilities; a theory of conceptual truth that allows us to make useful sense of a variety of conceptual falsehoods; and a theory of our understanding of necessity and possibility that permits impossibilities to be conceived. After discussing these questions, strategies for resisting (...) the picture of impossible fictions presented here and in Part I are discussed. Perhaps apparently impossible fictions describe possibilities after all; or perhaps impossible fictions are all trivial; or perhaps some apparently intelligible impossible fictions are unintelligible after all.

Hilary Putnam once proposed a semantic approach to, as well as a deflationist resolution of, the problem of analyticity. I take up and defend both ideas. First of all, I defend Putnam's semantic construal of the issue against Quine's reductive understanding. Secondly, I devise a semantics that successfully explains the genesis of the relevant analytic truths and that shows them to be harmless. Finally, I rebut the aspirations of the neo-descriptivist semantics, prominently propounded by David Chalmers and Frank Jackson, that (...) is widely presumed to spearhead the re-establishment of substantial analyticities. I conclude that analytic truths—at least those discussed—are indeed harmless. (shrink)

Some philosophers argue that many contemporary debates in metaphysics are “illegitimate,” “shallow,” or “trivial,” and that “contemporary analytic metaphysics, a professional activity engaged in by some extremely intelligent and morally serious people, fails to qualify as part of the enlightened pursuit of objective truth, and should be discontinued” (Ladyman and Ross, Every thing must go: Metaphysics naturalized , 2007 ). Many of these critics are explicit about their sympathies with Rudolf Carnap and his circle, calling themselves ‘neo-positivists’ or ‘neo-Carnapians.’ Yet (...) despite the fact that one of the main conclusions of logical positivism was that metaphysical statements are meaningless, many of these neo-positivists are themselves engaged in metaphysical projects. This paper aims to clarify how we may see a neo-positivist metaphysics as proceeding in good faith, one that starts with serious engagement with the findings of science, particularly fundamental physics, but also has room for traditional, armchair methods.

Wave function realism is an interpretative framework for quantum theories which recommends taking the central ontology of these theories to consist of the quantum wave function, understood as a field on a high-dimensional space. This paper presents and evaluates three standard arguments for wave function realism, and clarifies the sort of ontological framework these arguments support.

The question “What are cognitive processes?” can be understood variously as meaning “What is the nature of cognitive processes?”, “Can we distinguish epistemically cognitive processes from physical and biochemical processes on the one hand, and from mental or conscious processes on the other?”, and “Can we establish a fruitful notion of cognitive process?” The present aim is to deliver a positive answer to the last question by developing criteria for what would count as a paradigmatic exemplar of a cognitive process, (...) and then to offer the comparator mechanism as a convincing paradigmatic example. Thus, the paper argues, given the current state of science, we can indeed establish a fruitful scientific notion of a cognitive process. Nevertheless, it is left open whether the example-based characterization ends up as merely highlighting a fruitful convention within the early-twentyfirst century interdisciplinary investigation of intelligent behaviour in humans, animals, and robots, or whether the examples determine a natural kind or a property cluster.

This article is on political normativity. It urges scepticism about attempts to reduce political normativity to morality. Modern liberalism leaves a question about how far morality can be accommodated by the form of normativity characteristic of politics. The article casts doubt on whether individual moral norms carry over to collective, for example, political, action, and whether the former ‘trump’ other kinds of reasons in politics. It then sketches an alternative view of politics as an irreducibly collective enterprise. Reasons for acting (...) politically, including the understandings on which perceptions of legitimacy rest, are largely artefacts of the political culture and thus only marginally subject to generic conditions of validity: this is true in particular of liberal acceptability-conditions. Thus legitimacy, though not a redundant notion, must be geared to local political norms. (shrink)

Contrary to the common-sense view and positivist aspirations, scientific concepts are often imprecise. Many of these concepts are ambiguous, vague, or have an under-specified meaning. In this paper, I discuss how imprecise concepts promote integration in biology and thus benefit science. Previous discussions of this issue focus on the concepts of molecular gene and evolutionary novelty. The concept of molecular gene helps biologists integrate explanatory practices, while the notion of evolutionary novelty helps them integrate research questions into an interdisciplinary problem (...) New directions in the philosophy of science, Springer, Dordrecht, 2014). In what follows, I compare molecular gene and evolutionary novelty to another imprecise concept, namely biological lineage. This concept promotes two other types of scientific integration: it helps biologists integrate theoretical principles and methodologies into different areas of biology. The concept of biological lineage facilitates these types of integration because it is broad and under-specified in ways that the concepts of molecular gene and evolutionary novelty are not. Hence, I use the concept of biological lineage as a case study to reveal types of integration that have been overlooked by philosophers. This case study also shows that even very imprecise concepts can be beneficial to scientific practice. (shrink)

Susanna Schellenberg develops a unified account—“capacitism”—of perceptual content, phenomenology, and epistemic force. In this paper, I raise questions about her arguments for a capacitist account of evidential force, and then challenge her claim that such an account, even if correct, demands that our evidence be less than fully transparent to us.

Appeals to some thesis of underdetermination, to the idea that scientific theories and hypotheses are not entailed by the evidence that supports them, are common in feminist philosophy of science. These appeals seek to understand and explain how androcentrism and other problematic approaches to gender have found their way into good science, as well as the reverse – how feminist approaches to gender and science that are also value-laden, can contribute to good science. Focusing on W.V. Quine’s positions on holism (...) and underdetermination, I argue that although Quine’s general thesis of holism does not entail his thesis of global underdetermination, his account of and arguments for moderate holism entail a localized and generalizable underdetermination, which I call moderate underdetermination. This moderate underdetermination is not transient or true of only some theories and hypotheses. Rather, it is a permanent state of affairs that characterizes all reasonably inclusive theories and hypotheses, however much evidence for them accumulates. I contend that Quine’s moderate holism entails the most robust and defensible argument for localized underdetermination, and that feminists would do well to appeal to it in arguing that values inform good science.

In this paper, it is argued that both the belief state and its input should be represented as epistemic entrenchment (EE) relations. A belief revision operation is constructed that updates a given EE relation to a new one in light of an evidential EE relation, and an axiomatic characterization of this operation is given. Unlike most belief revision operations, the one developed here can handle both multiple belief revision and iterated belief revision.

La propuesta de naturalización de la epistemología explicitada por Quine en su célebre artículo de 1969 ha generado debates y consecuencias que de algún modo se prolongan hasta nuestros días a través de la evaluación de diversas propuestas de naturalización, todas ellas de algún modo vinculadas a la idea original de Quine. Sin embargo, varios aspectos bastante centrales de su propuesta continúan sin ser suficientemente aclarados. Ni siquiera se ha logrado consenso sobre cuáles serían las tareas específicas de una epistemología (...) naturalizada y cuáles retoma de la tradición. La persistencia de dichos debates no debería resultar sorprendente si uno considera que, al menos para la interpretación inicial, se estaría proponiendo un programa descriptivo para una disciplina que tenía un propósito claramente normativo; o que se estaba proponiendo apoyarse en las ciencias cuando la disciplina había nacido precisamente para fundamentar a esos estudios. Incluso, que se trataba de proponer una filosofía luego que se prescindiera de la aprioridad y de la analiticidad, cuando la tradición había concebido a la filosofía justamente a partir de ese tipo de enunciados. Para colmo, la epistemología naturalizada proclamaba abiertamente que entre epistemología y ciencias no habría fundamentación sino circularidad supuestamente no ilegítima. Eran pues, varias y fundamentales las posiciones de la tradición que aparecían así claramente desafiadas. En este sentido, en este trabajo nos proponemos: 1 – Revisar sumariamente el contenido básico de la propuesta de naturalización en relación a los temas clásicos de la teoría del conocimiento. 2 – Analizar y evaluar la acusación de falta de normatividad de la epistemología naturalizada. 3 – Analizar el tema de la aprioridad y la analiticidad en relación a las tareas filosóficas de la epistemología naturalizada. 4 – Analizar el posible fundamento y la supuesta circularidad de la propuesta de naturalización.En todos los casos vamos a defender una interpretación algo alejada de la que ha sido mayoritaria y vamos a apoyarnos para ello en la propios desarrollos epistemológicos de Quine y en algunas aclaraciones realizadas por el autor en escritos tardíos. En el tema del fundamento y la circularidad creemos oportuno vincular su posición con la idea de equilibrio reflexivo de Goodman y con desarrollos más recientes en teoría de la justificación no lineal.

Discussions of conservatism in epistemology often fail to demonstrate that the principle of conservatism is supported by epistemic considerations. In this paper, I hope to show two things. First, there is a defensible version of the principle of conservatism, a version that applies only to what I will call our basic beliefs. Those who deny that conservatism is supported by epistemic considerations do so because they fail to take into account the necessarily social, diachronic and self-correcting nature of our epistemic (...) practice. Second, I will attempt to show how our basic beliefs are justified via this principle of conservatism. (shrink)

The debate over scientific or critical realism is characterized by confusion, which I claim is a result of approaching the issue from both modern and ‘postmodern’ perspectives. Modern thought is characterized by foundationalism in epistemology and representationalism in philosophy of language, while holism in epistemology and the theory of meaning as use in philosophy of language are postmodern. Typical forms of scientific realism (which seek referents for theoretical terms or correspondence accounts of the truth of scientific theories) are positions at (...) home only in a modern framework. Postmodern presuppositions of other participants in the debate account for the ability of opponents to talk past one another. (shrink)

In the following précis, I provide a summary of Interdisciplinary Foundations for the Science of Emotion. Much of what I say can be found in the “About the “Book” section of my book, although I provide some elaborations here. My summary focuses primarily on the central aim of the book, and the general strategy that I take in order to achieve my aim. What I present is a proposal for an interdisciplinary science of emotion. That proposal goes by the name (...) of meta-semantic pluralisme, and a central principle of this proposal is what I refer to as the α-ωe principle. My summary includes chapter summaries, which provides not only a more detailed account of my general strategy, but also a summary of the fruitfulness of this first principle for interdisciplinary research and theorizing in the science of emotion, including the work it can do in the areas of metaphysics, language, consciousness, intentionality, rationality, and epistemology. Finally, one should note that some of the contents of this précis should also provide a response to at least some of the commentators’ requests for clarification, and I address the concerns not covered in this précis in my subsequent replies.

Ayn Rand’s Objectivist epistemology is the foundation of an impressive, comprehensive, and integrated system of political philosophy, psychology, art, and literature. Friedrich Hayek’s operational system of epistemology and his analysis of the psychology of perception (presented primarily in The Sensory Order) is not as clearly integrated with his economics and political philosophy—and many have debated their consistency with one another. This paper engages in a comparative analysis of Rand’s and Hayek’s epistemology.

The axiom of infinity states that infinite sets exist. I will argue that this axiom lacks justification. I start by showing that the axiom is not self-evident, so it needs separate justification. Following Maddy’s :481–511, 1988) distinction, I argue that the axiom of infinity lacks both intrinsic and extrinsic justification. Crucial to my project is Skolem’s From Frege to Gödel: a source book in mathematical logic, 1879–1931, Cambridge, Harvard University Press, pp. 290–301, 1922) distinction between a theory of real sets, (...) and a theory of objects that theory calls “sets”. While Dedekind’s argument fails, his approach was correct: the axiom of infinity needs a justification it currently lacks. This epistemic situation is at variance with everyday mathematical practice. A dilemma ensues: should we relax epistemic standards or insist, in a skeptical vein, that a foundational problem has been ignored? (shrink)

This paper argues that several leading theories of subjunctive conditionals are incompatible with ordinary intuitions about what credences we ought to have in subjunctive conditionals. In short, our theory of subjunctives should intuitively display semantic humility, i.e. our semantic theory should deliver the truth conditions of sentences without pronouncing on whether those conditions actually obtain. In addition to describing intuitions about subjunctive conditionals, I argue that we can derive these ordinary intuitions from justified premises, and I answer a possible worry (...) for my derivation by refuting a subjunctive triviality result modeled on (Lewis 1976). I conclude that the debate over the correct theory of subjunctive conditionals requires settling meta-philosophical questions about the relative value of various virtues of first-order theories of subjunctive conditionals.

This paper argues that just as full beliefs can constitute knowledge, so can properties of your credence distribution. The resulting notion of probabilistic knowledge helps us give a natural account of knowledge ascriptions embedding language of subjective uncertainty, and a simple diagnosis of probabilistic analogs of Gettier cases. Just like propositional knowledge, probabilistic knowledge is factive, safe, and sensitive. And it helps us build knowledge-based norms of action without accepting implausible semantic assumptions or endorsing the claim that knowledge is interest-relative.
