Rastrearemos a refutação da necessidade de fundamentos ontológicos para teorias éticas de Putnam analisando sua trajetória por autores como Quine, Moore e Wittgenstein. Partiremos do naturalismo epistemológico de Quine para estabelecer sua base coerentista pragmática. Então, investigaremos seu distanciamento da ontologia conforme sua perspectiva wittgensteiniana do conceitualismo mooreano e platônico. Caracterizando Heidegger como alvo primário de sua crítica a uma necessidade de ontologia, afasta-se mesmo de Quine ao abraçar uma relatividade conceitual inspirada na mereologia e em jogos de linguagem para (...) estabelecer a objetividade da ética sem a necessidade de objetos. Por fim, a partir dessa definição, investigaremos a concepção de ética segundo Putnam, fortemente inspirada em Dewey e Aristóteles em diálogo com Levinas e Kant em prol de um “florescimento cognitivo humano”. Sua definição é breve e superficial, todavia clama que tais características sejam necessárias a fim de dar maleabilidade à ética, em contraponto a uma definição rígida e facilmente quebradiça tendo em vista o amplo descordo presente na filosofia moral. Esta flexibilidade não cairia em relativismo absoluto uma vez que preza a razoabilidade e progresso, assim como evitaria doutrinas danosas “anti-florescimento”. (shrink)

This paper addresses some problems related to the relation of truthmaking, especially those concerning its necessity, adopting an essentialist point of view and focusing on the nature of truthbearers. According to the orthodox view in truthmaker theory, the relation of truthmaking is necessary in some sense. Thus, an important question involves how the relation of truthmaking is made necessary. I adopt a version of Jonathan Lowe’s essentialist approach to this question. However, contra Lowe, I take token acts of predication as (...) the primary truthbearers. This is Peter Hanks’ view in the philosophy of language. I shall argue that some problems with the essentialist approach can be solved by taking the nature of token acts of predication to be the source of necessity in truthmaking. At the end of this paper, I shall also briefly outline two general consequences related to truthmaking that I suppose this move about truthbearers should have. (shrink)

SellarsMyth of The Given” strikes at the very heart of the foundationalist project of empiricism, while yet attempting to preserve the sound epistemological and ontological intuitions on which it draws. To achieve this, the fatal predicaments bound up with the concept of the given first must be identified and defused. The result is a cautious redefinition of both the given as a non-epistemological concept and the relation between observation and theory, direct knowledge and inferential knowledge.

In a recent article Brian Leiter concluded that a useful normative theory of adjudication is impossible. A normative theory of adjudication would be a theory that, among other things, identified the moral and political norms that judges ought to follow in determining the law for any particular legal dispute. Letter's elegant and subtle argument, stripped to its bones, runs as follows: Philosophers of law regard a correct normative theory of adjudication as being dependent upon an antecedent descriptive theory. The dependence (...) here, as Leiter describes it, is of a very strong sort and unique among philosophical theories: Any normative theory, to be acceptable, cannot depart from the actual practice of judges and lawyers. Consequently, the content of the normative side of the theory is simply to “continue to do what you've been doing,” supplemented, perhaps, by Holme's injunction to do it more selfconsciously and explicitly.

This chapter contains section titled: Criteria of Ontological Commitment: Two Examples ‘No Entity without Identity’: Identity Conditions for Objects Individuation Conditions, Identity Conditions, and Metaphysical Kinds Principles and Criteria of Identity.

This book offers an historically-informed critical assessment of Dummett's account of abstract objects, examining in detail some of the Fregean presuppositions whilst also engaging with recent work on the problem of abstract entities.

Traditionally, social entities (i.e., social properties, facts, kinds, groups, institutions, and structures) have not fallen within the purview of mainstream metaphysics. In this chapter, we consider whether the exclusion of social entities from mainstream metaphysics is philosophically warranted or if it instead rests on historical accident or bias. We examine three ways one might attempt to justify excluding social metaphysics from the domain of metaphysical inquiry and argue that each fails. Thus, we conclude that social entities are not justifiably excluded (...) from metaphysical inquiry. Finally, we ask how focusing on social entities could change the character of metaphysical inquiry. We suggest that starting from examples of social entities might lead metaphysicians to rethink the assumption that describing reality in terms of intrinsic, independent, and individualistic features is preferable to describing it in terms of relational, dependent, and non-individualistic features.

This paper draws on the notion of “objects of research” in psychology as clusters of phenomena (Feest in Philos Sci 84:1165–1176, 2017) to analyze the productive role of folk psychological concepts—and the operational definitions that arise from them—in the development of concepts in scientific psychology. Using the case study of similarity, I discuss the role of the folk psychological concept in the regimentation of different measures of similarity judgments. I propose that by giving rise to operational definitions that lead to (...) experimental dissociation on the one hand, and by providing the concept with unity on the other hand, the folk psychological concept generates a productive tension that facilitates empirical and theoretical development of the scientific concept.

Brain imaging provides ever more sensitive measures of structure and function relevant to human psychology and has revealed correlates for virtually every psychiatric disorder. Yet it plays no accepted role in psychiatric diagnosis beyond ruling out medical factors such as tumors or traumatic brain injuries. Why is brain imaging not used in the diagnosis of primary psychiatric disorders, such as depression, bipolar disease, schizophrenia, and attention-deficit hyperactivity disorder (ADHD)? This article addresses this question. It reviews the state of the art (...) in psychiatric imaging, including diagnostic and other applications, and explains the nonutility of diagnostic imaging in terms of aspects of both the current state of imaging and the current nature of psychiatric nosology. The likely future path by which imaging-based diagnoses will be incorporated into psychiatry is also discussed. By reviewing one well-known attempt to use SPECT scanning in psychiatric diagnosis, the article examines a real-world practice that illustrates several related points: the appeal of the idea of image-assisted diagnosis for physicians, patients and families, despite a lack of proven effectiveness, and the mismatch between the categories and dimensions of current nosology and those suggested by imaging.

In a circulated but heretofore unpublished 2001 paper, I argued that Leiter's analogy to Quine's 'naturalization of epistemology' does not do the philosophical work Leiter suggests. I revisit the issues in this new essay. I first show that Leiter's replies to my arguments fail. Most significantly, if — contrary to the genuinely naturalistic reading of Quine that I advanced — Quine is understood as claiming that we have no vantage point from which to address whether belief in scientific theories is (...) ever justified, it would not help Leiter's parallel. Given Leiter's way of drawing the parallel, the analogous position in the legal case would be not the Legal Realists' indeterminacy thesis, but the very different position that we have no vantage point from which to address whether legal decisions can ever be justified. I then go on to address the more important question of whether the indeterminacy thesis, if true, would support any replacement of important legal philosophical questions with empirical ones. Although Ronald Dworkin has argued against the indeterminacy thesis, if he were wrong on this issue, it would not in any way suggest that the questions with which Dworkin is centrally concerned cannot fruitfully be addressed. The indeterminacy thesis is a bone of contention in an ordinary philosophical debate between its proponents and Dworkin. Of course, if the determinacy thesis were true, no one should try to show that it is false, but this triviality lends no support to the kind of replacement proposal that Leiter proposes. I conclude with some general reflections on naturalism and philosophical methodology. (shrink)

Did the pragmatic turn encompass the linguistic turn in the history of philosophy? Or was the linguistic turn a turn away from pragmatism? Some commentators identify the so-called “eclipse” of pragmatism by analytic philosophy, especially during the Cold War era, as a turn away from pragmatist thinking. However, the historical evidence suggests that this narrative is little more than a myth. Pragmatism persisted, transforming into a more analytic variety under the influence of Quine and Putnam and, more recently, a continental (...) version in the hands of Richard Rorty and Cornel West. In this paper, I argue that proof of the linguistic turn’s presence as a moment in a broader pragmatic turn in philosophy can be garnered from close examination of a single article, W. V. O. Quine’s “Two Dogmas of Empiricism,” and a single issue: whether the analytic-synthetic distinction is philosophically defensible. (shrink)

Pragmatism, Experience, and the Given The doctrine of the Given is that subjects have direct non-inferential awareness of content of their experiences and apprehensions, and that some of a subject's beliefs are justified on the basis of that subject's awareness of her experiences and apprehensions. Pragmatist criticisms of the Given as a myth are shown here not only to be inadequate but to presuppose the Given. A model for a pragmatist account of the Given is then provided in terms of (...) refinements of Dewey's theory of experience. The doctrine of the Given is implicated in the functions of inquiry insofar as one must take it that experience is a source of justification. (shrink)

I revisit my 1993 paper on Putnam and mathematical realism focusing on the indispensability argument and how it has fared over the years. This argument starts from the claim that mathematics is an indispensable part of science and draws the conclusion, from holistic considerations about confirmation, that the ontology of science includes abstract objects as well as the physical entities science deals with.

Relying on inference to the best explanation requires one to hold the intuition that the world is ‘intelligible’, that is, such that states of affairs at least generally have explanations for their obtaining. I argue that metaphysical naturalists are rationally required to withhold this intuition, unless they cease to be naturalists. This is because all plausible naturalistic aetiologies of the intuition entail that the intuition and the state of affairs which it represents are not causally connected in an epistemically appropriate (...) way. Given that one ought to rely on IBE, naturalists are forced to pick the latter and change their world-view. Traditional theists, in contrast, do not face this predicament. This, I argue, is strong grounds for preferring traditional theism to naturalism. (shrink)

In “A well-founded solution to the generality problem,” Comesaña argues, inter alia, for three main claims. One is what I call the unavoidability claim: Any adequate epistemological theory needs to appeal, either implicitly or explicitly, to the notion of a belief’s being based on certain evidence. Another is what I call the legitimacy claim: It is perfectly legitimate to appeal to the basing relation in solving a problem for an epistemological theory. According to Comesaña, the legitimacy claim follows straightforwardly from (...) the unavoidability claim. The third one is what I call the basing solution claim: An appeal to the notion of basing relation is all we need to solve the generality problem for (process) reliabilism. In this paper, I will argue that the unavoidability claim and the basing solution claim are false and that the legitimacy claim might be true only in a qualified sense. (shrink)

Starting from the often-used metaphor of the “horizon of experience” this article discusses three different types of intercultural hermeneutics, which respectively conceive hermeneutic interpretation as a _widening_ of horizons, a _fusion_ of horizons, and a _dissemination_ of horizons. It is argued that these subsequent stages in the history of hermeneutics have their origin in—but are not fully restricted to—respectively premodern, modern and postmodern stages of globalization. Taking some striking moments of the encounter between Western and Chinese language and philosophy as (...) example, the particular merits and flaws of these three types of hermeneutics are being discussed. The claim defended is that although these different types of hermeneutics are mutually exclusive from a theoretical point of view, as interpreting beings in the current era we depend on each of these distinct hermeneutic practices and cannot avoid living them simultaneously.

The Analysis of Matter is perhaps best known for marking Russell's rejection of phenomenalism and his development of a variety of Lockean representationalism–-Russell's causal theory of perception. This occupies Part 2 of the work. Part 1, which is certainly less well known, contains many observations on twentieth-century physics. Unfortunately, Russell's discussion of relativity and the foundations of physical geometry is carried out in apparent ignorance of Reichenbach's and Carnap's investigations in the same period. The issue of conventionalism in its then (...) contemporary form is simply not discussed. The only writers of the period who appear to have had any influence on Russell's conception of the philosophical issues raised by relativity were Whitehead and Eddington. Even the work of A. A. Robb fails to receive any extended discussion;1 although Robb's causal theory is certainly relevant to many of Russell's concerns, especially those voiced in Part 3, regarding the construction of points and the topology of space-time. In the case of quantum mechanics, the idiosyncrasy of Russell's selection of topics is more understandable, since the Heisenberg and Schrödinger theories were only just discovered. Nevertheless, it seems bizarre to a contemporary reader that Russell should have given such emphasis2 to G. N. Lewis's suggestion that an atom emits light only when there is another atom to receive it–-a suggestion reminiscent of Leibniz, and one to which Russell frequently returns. In short, the philosophical problems of modern physics with which Russell deals seem remote from the perspective of post-positivist philosophy of physics. (shrink)

Écrire un livre sur les fondements empiriques de la signification qui reprenne la question tant débattue de la critique de l'analycité, de la traduction radicale et de l'indétermination de la traduction, d'un point de vue éclairant, précis, et renouvelé à bien des égards, est la gageure que relève Martin Montminy avec son excellent livre Les fondements empiriques de la signification. La thèse simple mais convaincante de l'auteur est que la critique de l'analycité et de la distinction entre analytique et synthétique, (...) comme critique de toute approche normative de la signification, est la voie d'entrée, le fil directeur et l'argument central des différentes thèses de Quine sur l'épistémologie naturalisée, le holisme épistémologique et l'indétermination de la traduction. C'est par ce biais qu'il défend une approche empirique de la signification liant toute théorie sémantique à des données empiriques en principe accessibles à un observateur. Par ce fil directeur, Montminy, dans une argumentation toujours claire et explicite, offre à la fois une introduction pédagogique au. (shrink)

We need not accommodate facts about meaning if Quine is right about the indeterminacy of subsentential expressions; there can be no such facts to accommodate. Evans argued that Quine's approach overlooks the ways speakers use predication to endow their use of subsentential expressions with the necessary determinacy. This paper offers a critical assessment of the debate in relation to current arguments about naturalism and shows how Evans's response depends on a basic claim that turns out to be false.

Evolutionary reliabilism is the view that natural selection likely favoured reliable cognitive faculties in humans. While ER enjoys some plausibility, Stephen Stich and Alvin Plantinga have presented well-known challenges to the view. Their arguments rely on a common premiss; namely, that natural selection is indifferent to truth. This article shows that this premiss is both imprecise and too weak to support their conclusions and, therefore, that their challenges to ER fail.

The problem of nonreflectors perceived as colored is the central problem for Byrne & Hilbert's (B&H's) physicalism. Vision scientists and other interested parties need to consider the motivation for their account of “productance physicalism.” Is B&H's theory motivated by scientific concerns or by philosophical interests intended to preserve a physicalist account of color as a posteriori necessary?

Reflectance physicalism only provides a partial picture of the ontology of color. Byrne & Hilbert’ account is unsatisfactory because the replacement of reflectance functions by productance functions is ad hoc, unclear, and only leads to new problems. Furthermore, the effects of color contrast and differences in illumination are not really taken seriously: Too many “real” colors are tacitly dismissed as illusory, and this for arbitrary reasons. We claim that there cannot be an all-embracing ontology for color.

What are the consequences of evolutionary theory for the epistemic standing of our beliefs? Evolutionary considerations can be used to either justify or debunk a variety of beliefs. This paper argues that evolutionary approaches to human cognition must at least allow for approximately reliable cognitive capacities. Approaches that portray human cognition as so deeply biased and deficient that no knowledge is possible are internally incoherent and self-defeating. As evolutionary theory offers the current best hope for a naturalistic epistemology, evolutionary approaches (...) to epistemic justification seem to be committed to the view that our sensory systems and belief-formation processes are at least approximately accurate. However, for that reason they are vulnerable to the charge of circularity, and their success seems to be limited to commonsense beliefs. This paper offers an extension of evolutionary arguments by considering the use of external media in human cognitive processes: we suggest that the way humans supplement their evolved cognitive capacities with external tools may provide an effective way to increase the reliability of their beliefs and to counter evolved cognitive biases.

Our ability for scientific reasoning is a byproduct of cognitive faculties that evolved in response to problems related to survival and reproduction. Does this observation increase the epistemic standing of science, or should we treat scientific knowledge with suspicion? The conclusions one draws from applying evolutionary theory to scientific beliefs depend to an important extent on the validity of evolutionary arguments (EAs) or evolutionary debunking arguments (EDAs). In this paper we show through an analytical model that cultural transmission of scientific (...) knowledge can lead toward representations that are more truth-approximating or more efficient at solving science-related problems under a broad range of circumstances, even under conditions where human cognitive faculties would be further off the mark than they actually are.

In recent years philosophers have been interested in the methodology of metaphysics. Most of these developments are related to formal work in logic or physics, often against the backdrop of the Carnap-Quine debate on ontology. Drawing on Quine’s later work, I argue that a psychological or cognitive perspective on metaphysical topics may be a valuable addition to contemporary metametaphysics. The method is illustrated by means of cognitive studies of the notions “identity,” “vagueness,” and “object” and is compared to other extant (...) metametaphysical positions. (shrink)

This paper argues that phenomenal or internal metrical spaces are redundant posits. It is shown that we need not posit an internal space-time frame, as the physical space-time suffices to explain geometrical perception, memory and planning. More than the internal space-time frame, the idea of a phenomenal colour space has lent credibility to the idea of internal spaces. It is argued that there is no phenomenal colour space that underlies the various psychophysical colour spaces; it is parasitic upon physical and (...) psychophysical colour spaces. The argumentation is further extended to other sensory spaces and generalised quality spaces. (shrink)

Two questions are raised about Quine's view of truth. He has recently said that ontology is relative to a translation manual: is this the same as relativizing it to a language? The same question may be asked about truth. Should we think there is one concept of truth which is relative to a language, or is there a separate concept for each language (or speaker)? The second question concerns Quine's repeated endorsements of the ?disquotational? account of truth. Does he think (...) this account limits a truth predicate to application to a single language, or can translation (or Tarski's methods) allow us to apply a truth predicate in one language to sentences in other languages? If the latter, can Quine still contend that the disquotational account is a ?full? account of the concept of truth? The answer would tell us whether Quine can be counted among those who would deflate the concept of truth. (shrink)

SummaryStarting with Descartes, epistemology has been almost entirely based on first person knowledge. We must begin, according to the usual story, with what is most certain: knowledge of our own sensations and thoughts. In one way or another we then progress, if we can, to knowledge of an objective external world. There is then the final, tenuous, step to knowledge of other minds.In this paper I argue for a total revision of this picture. All propositional thought, whether positive or skeptical, (...) whether of the inner or of the outer, requires possession of the concept of objective truth, and this concept is accessible only to those creatures in communication with others. Third person knowledge – knowledge of other minds – is thus conceptually basic. But such knowledge is impossible without knowledge of a shared world of objects in a shared time and space. Thus the acquisition of knowledge is not based on a progression from the subjective to the objective; it emerges holistically, and is interpersonal from the start. (shrink)

Recently, several epistemologists have defended an attractive principle of epistemic rationality, which we shall call Ur-Prior Conditionalization. In this essay, I ask whether we can justify this principle by appealing to the epistemic goal of accuracy. I argue that any such accuracy-based argument will be in tension with Evidence Externalism, i.e., the view that agent's evidence may entail non-trivial propositions about the external world. This is because any such argument will crucially require the assumption that, independently of all empirical evidence, (...) it is rational for an agent to be certain that her evidence will always include truths, and that she will always have perfect introspective access to her own evidence. This assumption is in tension with Evidence Externalism. I go on to suggest that even if we don't accept Evidence Externalism, the prospects for any accuracy-based justification for Ur-Prior Conditionalization are bleak. (shrink)

In this paper I shall argue on Rortyan grounds that the two prima facie conflicting trends in contemporary philosophy, i.e. socialising and naturalising the mind should go hand in hand. First, I shall discuss socialising and naturalising tendencies as anti-sceptical strategies. Then I shall challenge both approaches and sketch out that they can be used together to solve some of their central problems. I shall recall how socially minded philosophers tend to ignore the non-social and argue that a naturalistic explanation (...) of the genesis of social practices is a suitable way for them to connect the social to the physical. Then I shall argue, in return, that naturalism could be supported by socio-historical approaches where two phenomena that are hard to naturalise are concerned: the first-person perspective on one hand, and normativity on the other. For these reasons, cooperation rather than ignorance and/or conflict between naturalists and socio-historicists would be desirable.My aim is not to develop an anti-Cartesian argument. That has been done by the authors I directly or indirectly refer to. Neither is my aim to show that naturalism or socio-historicism alone could not do the job. They probably could. My point is twofold, consisting of a descriptive and a normative claim: first, to demonstrate convergences between two recent, prima facie conflicting trends in recent history of philosophy ; and second, to argue that it is more efficient and more economical for these trends to cooperate because one can easily support the weaknesses of the other. Hence, my suggestion that naturalism and socio-historicism should act as allies in the face of their common enemy, rather than as one another’s enemies. (shrink)

This article addresses the problem of emergence through a distinction, often neglected in the literature, between two different aspects of this issue: (1) the theoretical problem of providing modelizations able to explain the expression of emergent properties; (2) the epistemological problem of warranting the scientific value of the emergentist descriptions of nature. This paper considers this double issue with regard to the biological domain, and proposes a double solution (theoretical and epistemological) originally developed in early studies on self-organization. The underlying (...) hypothesis is that this solution offers the current biological emergentism the opportunity of developing a coherent structure: matching consistently the theoretical and the epistemological frames of the research, that is, coupling the emergentist conception of life with an emergentist conception of science.

After a few general observations on scientific activity, the author briefly comments on different versions of naturalism. Subsequently, he suggests that the birth of evolutionary biology and its successive developments may show how the natural world comes to be differently conceived as scientific advancements are accomplished. Then the main thesis is outlined by introducing the principles of a heuristic science-based naturalism not conclusively defining the real and the knowable. From the epistemological perspective, heuristic naturalism is meant to be framed in (...) critical realism, whereas from the ontological standpoint it may be framed in emergent monism, given that the latter can also underpin recent trends in investigation addressing human specificity. Finally, attention is turned to some implications of heuristically guided scientific activity with regard to the issues of divine action and of imago Dei. (shrink)

Do numbers exist? Do properties? Do possible worlds? Do fictional characters? Many metaphysicians spend time and effort trying to answer these and other questions about the existence of various entities. These inquiries have recently encountered opposition: a group of philosophers, drawing inspiration from Aristotle, have argued that many or all of the existence questions debated by metaphysicians can be answered trivially, and so are not worth debating. Our task is to defend existence questions from the neo-Aristotelians' attacks.

According to epistemic instrumentalism, epistemic normativity arises from and depends on facts about our ends. On that view, a consideration C is an epistemic reason for a subject S to Φ only if Φ-ing would promote an end that S has. However, according to the Too Few Epistemic Reasons objection, this cannot be correct since there are cases in which, intuitively, C is an epistemic reason for S to Φ even though Φ-ing would not promote any of S’s ends. After (...) clarifying both EI and the Too Few Epistemic Reasons objection, I examine three major instrumentalist replies and argue that none of them is satisfactory. I end by briefly sketching a fourth possible response, which is, I suggest, more promising than the other three. (shrink)

Après avoir indiqué ce qu’il entend par Mathématiques pures et par Théorie de la connaissance, Vuillemin annonce, dans l’Introduction au premier tome de La Philosophie de l’algèbre, que son but est double. En considérant le « rapport étroit » et l’« affinité d’inspiration » entre ces deux disciplines, il se propose d’examiner, d’une part, « comment une connaissance pure est possible » et, d’autre part, de « critiquer, reformer et définir, autant qu’il se pourra, la méthode propre à la philosophie (...) théorique » grâce aux « analogies » repérées dans la connaissance mathématique. Ce double but dérive du constat, reposant sur l’analyse de l’histoire des mathématiques et de la philosophie, qu’« un renouvellement des méthodes de celles-là a, à chaque fois, des répercussions sur celle-ci ». Les renouvellements des méthodes que les mathématiques modernes induisent portent essentiellement, selon Vuillemin, sur les notions de structure, d’infini et de logique. Le deuxième tome de La Philosophie de l’algèbre devait donc montrer comment définir la méthode propre à la philosophie théorique. On essaiera de montrer comment le dernier chapitre du premier tome de cet ouvrage contient en soi des difficultés qui commanderont l’abandon du projet et comment l’idée de pluralisme qui y est esquissée exige une refonte conceptuelle que Vuillemin ne fournira que plus de vingt ans après.

It is widely believed that empiricism, though once dominant, is now extinct. This turns out to be mistaken because of incorrect assumption about the initial dominance of logical empiricism and about the content and variety of logical empiricist views. In fact, prominent contemporary philosophers (Quine and Kuhn) who are thought to have demolished logical empiricism are shown to exhibit central views of the logical empiricists rather than having overthrown them.
