Throughout his career, Husserl identifies naturalism as the greatest threat to both the sciences and philosophy. In this paper, I explicate Husserl’s overall diagnosis and critique of naturalism and then examine the specific transcendental aspect of his critique. Husserl agreed with the Neo-Kantians in rejecting naturalism. He has three major critiques of naturalism: First, it (like psychologism and for the same reasons) is ‘countersensical’ in that it denies the very ideal laws that it needs for its own justification. Second, naturalism (...) essentially misconstrues consciousness by treating it as a part of the world. Third, naturalism is the inevitable consequence of a certain rigidification of the ‘natural attitude’ into what Husserl calls the ‘naturalistic attitude’. This naturalistic attitude ‘reifies’ and it ‘absolutizes’ the world such that it is treated as taken-for-granted and ‘obvious’. Husserl’s transcendental phenomenological analysis, however, discloses that the natural attitude is, despite its omnipresence in everyday life, not primary, but in fact is relative to the ‘absolute’ transcendental attitude. The mature Husserl’s critique of naturalism is therefore based on his acceptance of the absolute priority of the transcendental attitude . The paradox remains that we must start from and, in a sense, return to the natural attitude, while, at the same time, restricting this attitude through the on-going transcendental vigilance of the universal epoché.

Since 1976 Hilary Putnam has drawn parallels between his "internal", "pragmatic", "natural" or "common-sense" realism and Kant's transcendental idealism. Putnam reads Kant as rejecting the then current metaphysical picture with its in-built assumptions of a unique, mind-independent world, and truth understood as correspondence between the mind and that ready-made world. Putnam reads Kant as overcoming the false dichotomies inherent in that picture and even finds some glimmerings of conceptual relativity in Kant's proposed solution. Furthermore, Putnam reads Kant as overcoming the (...) pernicious scientific realist distinction between primary and secondary qualities, between things that really exist and their projections, a distinction that haunts modern philosophy. Putnam's revitalisation of Kant is not just of historical interest, but challenges contemporary versions of scientific realism. Furthermore, Putnam has highlighted themes which have not received the attention they deserve in Kantian exegesis, namely, the problematic role of primary and secondary qualities in Kant's empirical realism, and the extent of Kant's commitment to conceptual pluralism.However, I argue that Putnam's qualified allegiance to Kant exposes him to some of the same metaphysical problems that affected Kant, namely, the familiar problem of postulating an absolute reality (Ding an sich), while at the same time disavowing the meaningfulness of so doing. In conclusion I suggest that Putnam might consider Hegel's attempts to solve this problem in Kant as a way of furthering his own natural realism. (shrink)

In this response to the review of Moore, Causation and Responsibility, by Larry Alexander and Kimberly Ferzan, previously published in this journal, two issues are discussed. The first is whether causation, counterfactual dependence, moral blame, and culpability, are all scalar properties or relations, that is, matters of more-or-less rather than either-or. The second issue discussed is whether deontological moral obligation is best described as a prohibition against using another as a means, or rather, as a prohibition on an agent strongly (...) causing a prohibited result that was not about to happen anyway while intending to do so.

According to the eligibility theory of meaning, often attributed to David Lewis, the referent of a predicate is the property that best balances the twin constraints of charity and eligibility, where eligibility is a function of metaphysical naturalness. This sort of metasemantics, which is motivated by its ability to resolve problems of indeterminacy and secure shared reference between disputing parties, can be somewhat friendly towards revisionary theories, since highly natural properties can act as “reference magnets,” securing our reference despite some (...) mismatch with usage. In this paper, I apply these considerations to normative ethics and argue that the theory of rule utilitarianism achieves a high balance of charity and eligibility. I proceed by comparing rule utilitarianism to two of its well-known rivals, act utilitarianism and Rossian pluralism. I show how the former achieves a high degree of eligibility but only at a significant cost of charity, while the latter does the opposite, fitting very nicely with our considered judgments but at the price of very low eligibility. Rule utilitarianism, on the other hand, strikes a good balance between these extremes; it assigns to our core moral term a relatively natural property without doing too much damage to our moral convictions. Thus, rule utilitarianism should be regarded as a promising moral theory by any philosopher who takes seriously considerations of eligibility and naturalness. (shrink)

The Moral Twin Earth challenge to ethical naturalism threatens to undermine an otherwise promising metaethical view by showing that typical, naturalist-friendly theories of reference determination predict diverging reference in Twin Earth scenarios, making it difficult to account for substantive moral disagreement. Several theorists have recently invoked David Lewis’s doctrine of reference magnetism as a solution, claiming that a highly elite moral property—a moral “joint in nature”—could secure shared reference between ourselves and our twins on Twin Earth, despite our diverging usages (...) of moral terms. This paper argues that this move has significant methodological implications: namely, it entails that a certain sort of simplicity is truth-conducive. Consequently, when applied to moral theories, this gives certain views, specifically monist ones like utilitarianism and contractualism, an advantage over their more complicated rivals, forms of pluralism and particularism. Thus, ethical naturalists cannot invoke reference magnetism without a substantial impact on first-order theorizing. (shrink)

In "Realism and Reason" Hilary Putnam has offered an apparently strong argument that the position of metaphysical realism provides an incoherent model of the relation of a correct scientific theory to the world. However, although Putnam's attack upon the notion of the "intended" interpretation of a scientific theory is sound, it is shown here that realism may be formulated in such a way that the realist need make no appeal to any "intended" interpretation of such a theory. Consequently, it can (...) be shown that realism is immune to Putnam's criticism and that attempts at reformulating this criticism are not likely to meet with success. (shrink)

Five years have passed since the death of Hilary Putnam. Through this symposium, we would like to celebrate the thought and work of one of the most influential, imaginative, fine, distinctive, and often provocative minds in twentieth-century American philosophy. We do not seek to do this through an entirely eulogizing approach; rather, we want to recognize the limits and challenges of his thought, as well as its potential generativity. The authors of this symposium engage with Putnam’s work n...

Rudolf Carnap’s principle of tolerance states that there is no need to justify the adoption of a logic by philosophical means. Carnap uses the freedom provided by this principle in his philosophy of mathematics: he wants to capture the idea that mathematical truth is a matter of linguistic rules by relying on a strong metalanguage with infinitary inference rules. In this paper, I give a new interpretation of an argument by E. W. Beth, which shows that the principle of tolerance (...) does not suffice to remove all obstacles to the employment of infinitary rules. (shrink)

: Radical sceptical possibilities challenge the anti-realist view that truth consists in ideal rational acceptability. Putnam, as part of his defence of an anti-realist view, subjected the case of the brain in a vat to a semantic externalist treatment, which aimed to maintain the desired connection between truth and ideal rational acceptability. It is argued here that self-consciousness poses special problems for this externalist strategy. It is shown how, on a standard model of first-person reference, Putnam's brain in a vat (...) will be mistaken in its rational self-ascription of externalist predicates. The natural response, which employs an alternative model of first-person reference, is shown to have the equally realist consequence that there are enquiry-transcendent truths about the self.

The idea that science aspires to and routinely achieves truths about the world has been challenged in recent writings. Rather than beginning with a theory of scientific development, or of scientific explanation, we begin with a consideration of truth claims in ordinary discourse, particularly with Davidson's truth-functional semantics. Next we consider the way in which some framework features of ordinary language discourse are extended to and modified in scientific discourse. Two areas are treated in more detail: quantum theory, and the (...) peculiar problem of semantic entailment it involves; and quantum field theory. These supply a basis for criticizing some historicist and logicist treatments of the truth of scientific claims. (shrink)

Despite widespread confusion over its meaning, the notion of a conceptual scheme is pervasive in Anglo-American philosophy, particularly amongst those who call themselves ' conceptual relativists'. In this paper, I identify three different ways to understand conceptual schemes. I argue that the two most common models, deriving from Kant and Quine, are flawed, and, in addition, useless for the relativist. Instead, I urge adoption of a 'neo-Kantian', broadly Wittgensteinian model, which, it is ' argued, is immune from Davidsonian objections to (...) the very idea of a scheme. (shrink)

I admire Wilson & Sober's (W & S's) aim, to alert social scientists that group selection has risen from the ashqs, and to explicate its relevance to the behavioral sciences. Group selection has beenwidely misunderstood; furthermore, both authors have been instrumental in illuminating conceptual problems surrounding higher-level selection. Still, I find that this target article muddies the waters, primarily through its shifting and confused definition of a "vehicle" of selection. The fundamental problem is an ambiguity in the definition of "adaptation." (...) On the one hand, any evolutionary change that results from a selection process could be called an adaptation, by definition; I call this the "weak" view of adaptation. A "strong" view of adaptation, on the other hand, includes some notion of design - the evolution of a specific complex trait understood, in an engineering sense, to provide a mechanism favoring its owner's success in contributing to the evolutionary lineage.

The article aims at deepening and making explicit the influence of pragmatism on the thought of Hilary Putnam, moving from the analysis of some of his earlier writings, in which the reference to pragmatism was still very much implicit. In particular, although focused on the classical neopositivist questions of the philosophy of science on which Putnam has been trained, the essays What Theories Are Not (1962) and The “Corroboration” of Theories (1974) betray some original pragmatist options already. The article will (...) review the pragmatist undertones in Putnam’s criticism of contemporary epistemology in order to test its promises. (shrink)

In order to develop his pragmatist and inferentialist framework, Robert Brandom appropriates, reconstructs and revises key themes in German Idealism such as the self-legislation of norms, the social institution of concepts and facts, a norm-oriented account of being and the critique of representationalist accounts of meaning and truth. However, these themes have an essential ethical dimension, one that Brandom has not explicitly acknowledged. For Hegel, the determination of norms and facts and the institution of normative statuses take place in the (...) context of Sittlichkeit (‘ethical life’). By engaging with some of the more ontologically and ethically substantive points raised by Hegel, I argue that, from a Hegelian perspective, Brandom’s project regarding the social determination of truth and meaning cannot be divorced from ethics, specifically, the ethical dimension of social recognition. Furthermore, I argue that, in real situations (as opposed to ideal ones), claims to normative authority cannot be considered independently from the legitimacy of those claims, a legitimacy that Brandom is unable to reasonably explain. Finally, I argue that a Hegelian solution to the problems facing Brandom’s framework calls into question the unity of reason that is at the core of Brandom’s normative pragmatics and inferential semantics.

The model-theoretic argument, which Putnam employs to argue againstmetaphysical realism, has faced serious objections of many realist opponents.Igor Douven in his recent paper offers a new interpretation of the model-theoreticargument, which avoids the previous objections. The purpose of this paper is toshow that Douven's reconstruction of Putnam's argument is not successful, andhence that the realist objections still stand.

Having suggested that a salient feature of philosophical naturalism is to deny that there are non‐natural norms, I make a distinction between a moderate naturalism, which admits the existence of natural norms, and a radical naturalism which denies it. On the assumption that intentional facts are irreducibly normative, their existence would thus seem to raise a problem for moderate epistemological naturalism. I argue that no non‐trivial naturalistic explanation of conceptual intentionality is to be possible unless it is denied that norms (...) of rationality are constitutive of intentional content. It follows that the only form of intentional naturalism that is not obviously untenable has to be radical. Other aspects of Quine's doctrine suggest that the introduction of epistemic norms into our “system of the world” is either dubiously coherent, or “merely programmatic”. (shrink)

There is a curious letter of 24 April 1928, reproduced in Russell’s Autobiography. It is from Russell to Max Newman. It is my thesis that there is a crucial “not” missing from the text and interpretations of the letter. This small point, if it is correct, has a very large impact for clarifying how Russell saw Newman’s challenge to his structural realism according to which all of our empirical knowledge in physics concerns structure alone.

The essay has two purposes. One is to point out connections and parallels between, On one hand, The debates of metaphysical realists and anti-Realists, And on the other hand, The debates surrounding moral realism. The second is to provide the outlines of a case for a kind of position that would generally be classified as moral realism. One feature of this position is that it emerges as parallel to, And compatible with, A metaphysical position that would generally be classified as (...) anti-Realism. (shrink)

The extensions of Goodman’s ‘grue’ predicate and Kripke’s ‘quus’ are constructed from the extensions of more familiar terms via a reinterpretation that permutes assignments of reference. Since this manoeuvre is at the heart of Putnam’s model-theoretic and permutation arguments against metaphysical realism (‘Putnam’s Paradox’), both Goodman’s New Riddle of Induction and the paradox about meaning that Kripke attributes to Wittgenstein are instances of Putnam’s. Evidence cannot selectively confirm the green-hypothesis and disconfirm the grue-hypothesis, because the theory of which the green-hypothesis (...) is a part has an unintended model in which the grue-hypothesis is equally confirmed; and there are no meaning-facts that determine reference, because the objects referred to by the referring terms of any language or set of intentional mental states are permutable in a way that is consistent with the truth-values of all other sentences in that language or beliefs in that set. The upshot is that the three paradoxes need to be solved in a unified way. (shrink)

The linguistic theory of the logical A Priori: is it obsolete In holistic interpretations, the logical truths are considered as continuous with empirical science: they are revisable, a posteriori, though very near to the centre of our web of belief. In this paper, we consider the merits and demerits of this approach, and we propose that it is necessary to revaluate holistic philosophies of logic. Some arguments are put forward which point in favour of the logical empiricists’ theory of logical (...) truth. We argue (following Hartry Field) that the concept of “correlation between logical facts and logical beliefs” (which is at the heart of the holistic theory) is inconsistent. Finally, we concentrate on the principle of contradiction and argue (following Manley Thompson) that this principle is fundamental for meaning, truth, and thinking. This thesis is derived from considerations on the nature of intentionality. (shrink)

After drawing attention to the basic importance of Goodman's workThe Structure of Appearance, this paper turns to a critical analysis of Goodman's claims concerning worldmaking. It stresses that Goodman's acceptance of a multiplicity of actual worlds doesnot involve the belief in an unknowable underlying reality; but that it is due to the non-mysterious fact that constructional systems allow for a multiplicity of disagreeing, right versions. However, from the point of view of truthmaker ontology, most worlds of constructional systems are not (...) genuine worlds; and so far it hasnot been shown that there are genuine truthmaker worlds that disagree.It is suggested that the construction of systems usually involves three conflicting aims: the logical, the ontological, and the psychological. Considering the current interest in cognitive psychology and phenomenology, the implications of the psychological aim, too, deserve to be reexamined. (shrink)

In the first part ("Determination"), I consider different notions of determination, contrast and compare modal with non-modal accounts and then defend two a-modality theses concerning essence and supervenience. I argue, first, that essence is a a-modal notion, i.e. not usefully analysed in terms of metaphysical modality, and then, contra Kit Fine, that essential properties can be exemplified contingently. I argue, second, that supervenience is also an a-modal notion, and that it should be analysed in terms of constitution relations between properties. (...) In the second part ("A Theory of Truthmaking"), I first review the literature on ontological commitment, and argue that the notion of truthmaking is better suited to play its explanatory rôle. I then argue that we should take truthmaker theory seriously, and that we should provide actual truthmakers for all truths there are. In the last chapter of this part, I review Armstrong's truthmaker theories and argue that they are unsatisfactory. I generalise my criticism to an argument against truthmaker necessitarianism, the view that truthmakers necessarily make true the truths they are truthmakers of. In the third part ("Properties and their Kind(s)"), I discuss qualitative determination. I present and endorse the truthmaker argument for universals, and defend universalism against friends of tropes, states of affairs and facts. I then give a novel characterisation of the important class of intrinsic properties, building on Lewis' work. With a workable notion of intrinsicness at hand, I argue that relations are ontologically – but not "ideologically" – dispensable: qualitative determination in general is a matter of intrinsic structure. In the future, I plan to add two parts and to publish my thesis as a book: In the fourth part ("Exemplification"), I argue for the existence of an exemplification relation tying universals and particulars together. I derive theoretical benefits from this relation by providing adverbialist theories of modality and tense and identify exemplification with a type of parthood. In the fifth part ("Qua qua qua"), I investigate the curious and interesting ontological category of so-called "qua-objects" (Picasso-as-a-painter, for example) and argue that they exist, are not identical with transworld indidivuals or modal parts and that they provide (contingent) truthmakers for all true predications.

In the paper I defend the idea of metametasemantics against the arguments recently presented by Ori Simchen. Simchen attacks the view, according to which metametasemantics incorporating all possible metasemantic accounts is necessary to protect the metasemantic theories from the notorious problem of inscrutability of reference. Simchen claims that if metametasemantics is allowed it ‘absorbs’ metasemantic theories to the extent that it diminishes their explanatory value. Furthermore, in this way Simchen sets up two main metasemantic paradigms i.e. productivism and interpretationism as (...) the rival theories inevitably excluding each other. I endeavour to undermine Simchen’s point by demonstrating that his argumentation mixes up deflationary reading of the predicate ‘is true’ with its substantial reading. Consequently, I demonstrate that accepting metametasemantics does not diminish explanatory value of various metasemantic theories and thus that there is no good reason to forbid metametasemantics. I also argue that even if we ignore the above-mentioned confusion in Simchen’s reasoning, his arguments still fail when considering various problems with the notion of diminishment of explanatory value and because the analogy that his arguments are based on is fairly weak. Eventually, I conclude that metametasemantics does not pose any danger to metasemantics and that it provides a solid ground for developing a theory that benefits from both productivism and interpretationism.

Pragmatism and the correspondence theory of truth are longtime foes. Nevertheless, there is an argument to be made that pragmatists must embrace truth as correspondence. I show that there is a distinctive pragmatic utility to taking truth to be correspondence, and I argue that it would be inconsistent for pragmatists to accept the utility of the belief that truth is correspondence while resisting the premise that this belief is correct. -/- In order to show how pragmatists can embrace truth as (...) correspondence, I develop a kind of alethic pluralism, which treats pragmatist truth as theoretically fundamental to truth as correspondence. This theoretical fundamentality of pragmatist truth allows the pragmatist to conditionally accept truth as correspondence for certain discourses without falling prey to the typical pragmatist objections to correspondence. This pluralist account of truth thus allows pragmatists to concede that, for certain domains of discourse, truth is correspondence, without thereby betraying their pragmatist principles. (shrink)

In this paper I question the view that realism must delineate the basic ontological furniture of the world rather than giving arguments in semantic or epistemic terms for the existence of a mind-independent world. I call this view of stating and defending realism the Ontological Defence of Realism (or ODR) and take Devitt's account of realism as a paradigmatic case of ODR. I argue that ODR cannot block ' verificationist antirealism' because the specific (physical) nature of what exists is not (...) enough to secure the mindindependence of what exists and, additionally, every element purported to achieve this, it compromises seriously the idea that realism is primarily an ontological issue. I also stress that ODR is in tension with a plausible realist insight namely the priority of the world over our theorizing. Because of this tension ODR weakens realism in several domains with no good reason. Specifically, I argue that in these domains ODR faces a dilemma: either to reject realism or to take realism to be dependent on a reductive account violating the realist insight. My point is that we should keep realism and ontology distinct and that compliance with the realist insight initiates a better strategy for the defence of realism. I address three possible objections thereby further clarifying my point. I conclude by presenting my view about the relation between ontology and realism. (shrink)

In her effort to recast moral realism in the style of the later Wittgensteinian philosophy of language, Sabina Lovibond seeks to ground moral knowledge in a historical community and its rules of language. In Stanley Hauerwas’ writings, we find an account of Christian ethics that is similarly modeled on Wittgensteinian realism. The main problem with Wittgensteinian moral realism, as it is appropriated by both Lovibond’s and Hauerwas’ society-dependent accounts of morality, is that they are unable to resolve difficult issues created (...) by epistemic relativism. Both thinkers are vulnerable to epistemic relativism in two ways. First, with its contextualist approach to the justification of moral beliefs, their conception of moral realism makes any historical community the ultimate authority in all matters of morality. Second, their conception of moral realism also turns moral truth into a social property of a historical community, while denying the exclusive ownership of truth by one particular community.

In “Models and Reality”, H. Putnam formulated his model-theoretic argument against “metaphysical realism”. The article proposes a meta-reconstruction of Putnam’s model-theoretic argument in the light of two mutually compatible interpretations of it–elaborated by Manuel Garcia-Carpintero and Igor van Douven. A critical reflection on these interpretations and their adequacy for Putnam’s argument allows us to expose new theses coherent with Putnam’s reasoning and indicate new paths to improve this argument for our reconstruction task. In particular, we show that Putnam’s position may (...) be coherent with van Douven’s versions of Global Descriptivism under some conditions, but Putnam cannot reject realism as quickly as Carpintero suggests. We show that Suszko’s canonic axiomatic system and Sneed’s concept of theory may provide valuable support for Putnam’s argument. Finally, we critically evaluate Carpintero’s theses about the genesis of unintended interpretations of our languages, adopting the machinery of the Upward Skolem–Loewenheim Theorem and Knight’s Theorem.

Hillary Putnam has famously argued that we can know that we are not brains in a vat because the hypothesis that we are is self-refuting. While Putnam's argument has generated interest primarily as a novel response to skepticism, his original use of the brain in a vat scenario was meant to illustrate a point about the "mind/world relationship." In particular, he intended it to be part of an argument against the coherence of metaphysical realism, and thus to be part of (...) a defense of his conception of truth as idealized rational acceptability. Putnam's conclusions about the scenario are, however, actually out of line with central and plausible aspects of his own account of the relationship between our minds and the world. Reflections on semantics give us no compelling reason to suppose that claims like "I am a brain in a vat" could not turn out to be true. (shrink)

To sum up, then, both kinds of Putnam's arguments established externalism, though they suffer from several defects. Yet, I think Searle's discussion of these arguments contributes to our understanding of what makes externalism true, and forces us to accept a moderate version of externalism. Searle's own account of the TE story shows us, within a solipsistic outline, how two identical mental states can be directed towards different objects, and further, that the content-determination of indexical thoughts does not necessarily involve external (...) factors. We are thus led to search elsewhere (i.e., not in the nature of indexical thoughts nor in the mere fact of there being identical thoughts with different intentionalities) for what makes the thoughts in question ‘external’. Searle formulates the thesis that intension determines extension as asserting that intension sets certain conditions that anything has to meet in order to fall under its extension. I showed that this is a trivial and implausible understanding of that thesis. Yet, it leads us to distinguish between an intension's setting conditions for falling under its extension and its fully determining such conditions, and thus to see in what sense externalism is true: in the sense that there are intensions that do not fully determine the conditions for falling under their extensions. Rather, they leave indeterminacies. This version of externalism is a moderate one, since though the intensions do not fully determine extensions, they, so to speak, determine their indeterminacies, by specifying the possible external facts that can complete the determination of extension. (The intensions, as I said, function like open sentences, and can be viewed as narrow contents.) So what's in the head plays a much more important role in determining content than Putnam takes it to play. Searle's pointing out that Hilary's concepts ‘elm’ and ‘beech’ are different also contributes to seeing this phenomenon: we realize that in that case the difference between the concepts is what is responsible for the fact that the completions of the extension-determinations are different. I think that this way of viewing the facts shows that ‘the externalist turn’ is not a great revolution, and that with the help of the concept of narrow content we can accept it without abandoning the traditional views about the mind as the source of content, and without being embarrassed by the very idea of (realistic) belief-desire psychology.

I investigate what it means to have an interpretation of our language, how we manage to bestow a determinate interpretation to our utterances, and to which extent our interpretation of the world is determinate. All this is done in dialogue with van Fraassen's insightful discussion of Putnam's model-theoretic argument and of scientific structuralism.

The Three Papers comprising this series, together with my earlier [34] also published in this journal, constitute an attempt to set out the major issues in the theoretical domain of reduction and to develop a general theory of theory reduction. The fourth paper, [34], though published separately from this trio, is integral to the presentation and should be read in conjunction with these papers. Even so, the presentation is limited in scope – roughly, to intertheoretic reduction among empirical theories – (...) and informal in presentation – not least because a satisfying formal account of theories has yet to be offered. And despite the length, the treatment is still condensed; often corroborating and/or intuitively helpful detail has had to be consigned to footnotes or omitted. I approach the problem from within my own naturalistic realist philosophy of science and formal analysis of abstract hierarchy in theory. The sources for the former are [25], [29], [31], and [32] and those for the latter essentially [27] and [30]. Hierarchical notions played a significant role in the already published [34]. (shrink)
