Structural realism is the view that scientific theories give us knowledge only of the structure of the unobservable world. The view faces an influential objection that was first posed by Max Newman: if our knowledge of the unobservable world were strictly limited to its structure, our knowledge turns out to be trivial, for it amounts to nothing more than knowledge of the cardinality of the world. In this paper, I shall propose a response to Newman’s objection. It shall be argued (...) that in having epistemic access to the intrinsic nature of our conscious experiences—knowledge that structural realists allow for—we have knowledge of what it is to exist as concrete phenomena. With the plausible assumption that the relations of the unobservable world are also similarly concrete, one can address Newman’s objection. I shall further contrast this response to other similar responses that have been proposed, and also address the objection that this response is not available to structural realists. (shrink)

In this paper I investigate how differences in approach to truth and logic (in particular, a deflationist vs. a substantivist approach to these fields) affect philosophers’ views concerning pluralism and normativity in these fields. My perspective on truth and logic is largely epistemic, focusing on the role of truth in knowledge (rather than on the use of the words “true” and “truth” in natural language), and my reference group includes Carnap (1934), Harman (1986), Horwich (1990), Wright (1992), Beall and Restall (...) (2006), Field (2009), Lynch (2009), and Sher (2016a).1 Whenever possible, I focus on positive rather than negative views on the issues involved, although in some cases this is not possible. (shrink)

Kant is known for having said relatively little about truth in Critique of Pure Reason. Nevertheless, there are important lessons to be learned from this work about truth, lessons that apply to the contemporary debate on the nature and structure of truth and its theory. In this paper I suggest two such lessons. The first lesson concerns the structure of a substantive theory of truth as contrasted with a deflationist theory; the second concerns the structure of a correspondence theory of (...) truth. The first lesson warns us against conceiving of a substantive theory of truth in a way that led Kant to conclude that such a theory is unviable. In so doing it indirectly suggests what a viable substantive theory of truth would be like. The second lesson teaches us that a correspondence theory of truth need not be as naive and overly simplistic as it is usually thought to be, but can, and should be, far more complex. This lesson is based on a correspondence theory of truth incipient in the Critique, one whose structure reflects the complexity of the relation between mind and world in Kant’s theory. (shrink)

Many philosophers are baffled by necessity. Humeans, in particular, are deeply disturbed by the idea of necessary laws of nature. In this paper I offer a systematic yet down to earth explanation of necessity and laws in terms of invariance. The type of invariance I employ for this purpose generalizes an invariance used in meta-logic. The main idea is that properties and relations in general have certain degrees of invariance, and some properties/relations have a stronger degree of invariance than others. (...) The degrees of invariance of highly-invariant properties are associated with high degrees of necessity of laws governing/describing these properties, and this explains the necessity of such laws both in logic and in science. This non-mysterious explanation has rich ramifications for both fields, including the formality of logic and mathematics, the apparent conflict between the contingency of science and the necessity of its laws, the difference between logical-mathematical, physical, and biological laws/principles, the abstract character of laws, the applicability of logic and mathematics to science, scientific realism, and logical-mathematical realism.

In this article, we redefine classical notions of theory reduction in such a way that model-theoretic preferential semantics becomes part of a realist depiction of this aspect of science. We offer a model-theoretic reconstruction of science in which theory succession or reduction is often better - or at a finer level of analysis - interpreted as the result of model succession or reduction. This analysis leads to 'defeasible reduction', defined as follows: The conjunction of the assumptions of a reducing theory (...) T with the definitions translating the vocabulary of a reduced theory T' to the vocabulary of T, defeasibly entails the assumptions of reduced T'. This relation of defeasible reduction offers, in the context of additional knowledge becoming available, articulation of a more flexible kind of reduction in theory development than in the classical case. Also, defeasible reduction is shown to solve the problems of entailment that classical homogeneous reduction encounters. Reduction in the defeasible sense is a practical device for studying the processes of science, since it is about highlighting different aspects of the same theory at different times of application, rather than about naive dreams concerning a metaphysical unity of science.

Formal semantic theories are generally thought to make contact with pre-theoretic semantic notions of aboutness and reference. The nature of that contact is, however, not always straightforward. This paper addresses two debates where that issue assumes a significant role. I begin with Simchen’s recent argument that Lewisian Interpretationism succumbs to referential indeterminacy. I develop a proposal about the relationship between the theoretical notion of a term’s semantic value and the pre-theoretic notion of reference, and argue that the indeterminacy Simchen identifies (...) does not constitute a form of referential indeterminacy. In the second part, I apply these resources to the debate between singularist and pluralist approaches to the semantics of plural terms, arguing that a certain form of singularism that emerges from the dialectic ends up agreeing with the pluralist at the level of reference, if not semantic value. The paper concludes with some remarks on what a properly referential style of singularism might look like. (shrink)

According to Sider, a question is metaphysically substantive just in case it has a single most natural answer. Recently, Barnes and Mikkola have argued that, given this notion of substantivity, many of the central questions in the metaphysics of gender are nonsubstantive. Specifically, it is plausible that gender pluralism—the view that there are multiple, equally natural gender kinds—is true, but this view seems incompatible with the substantivity of gender. The goal of this paper is to argue that the notion of (...) substantivity can be understood in a way that accommodates gender pluralism. First, I claim that gender terms (at least as used in the ontology room) are referentially indeterminate, where referential indeterminacy holds in virtue of the way the world is. Second, I propose a degree-theoretic (or scalar) account of metaphysical substantivity; genders are substantial to the degree that they are determinate. I conclude that gender is relatively, although not absolutely, substantial. (shrink)

In his theory of communication Schutz exhibits a significant tension between two fundamental perspectives, phenomenology and pragmatism, and in the long run he fails to reconcile the contradictory implications these perspectives have with regard to his model of interaction.The main problem seems to be the notion of sense-constitution. Schutz develops two distinguishable accounts of constitution: an egological one and a model based on the phenomenon of direct interaction of empirical subjects. Two key concepts are related to these different modes of (...) constitution: the model of appresentation with regard to language, symbols and signs, and the model of synchronisation as triangulation of streams of consciousness and outward action sequences. They are analyzed as significant for two different methods and two different theories of communication. I propose some reasons for Schutz's insistence on a phenomenological account of the ego and the constitution of sense, and offer a brief sketch of an alternative strategy that is implicit in Schutz's theory.

In the context of calls for "postpositivist" sociology, realism has emerged as a powerful and compelling epistemology for social science. In transferring and transforming scientific realism --a philosophy of natural science--into a justificatory discourse for social science, realism splits into two parts: a strict, highly naturalistic realism and a reflexive, more mediated, and critical realism. Both forms of realism, however, suffer from conceptual ambiguities, omissions, and elisions that make them an inappropriate epistemology for social science. Examination of these problems in (...) detail reveals how a different perspective--centered on the interpretation of meaning--could provide a better justification for social inquiry, and in particular a better understanding of sociological theory and the construction of sociological explanations.

A Philosopher Looks at Quantum Mechanics’ (Putnam [1965]) explained why the interpretation of quantum mechanics is a philosophical problem in detail, but with only the necessary minimum of technicalities, in the hope of making the difficulties intelligible to as wide an audience as possible. When I wrote it, I had not seen Bell ([1964]), nor (of course) had I seen Ghirardi et al. ([1986]). And I did not discuss the ‘Many Worlds’ interpretation. For all these reasons, I have decided to (...) make a similar attempt forty years later, taking account of additional interpretations and of our knowledge concerning non-locality. (The Quantum Logical interpretation proposed in Putnam [1968] is not considered in the present paper, however, because Putnam [1994b] concluded that it was unworkable.) Rather than advocate a particular interpretation, this paper classifies the possible kinds of interpretation, subject only to the constraints of a very broadly construed scientific realism. Section 7 does, however, argue that two sorts of interpretation—ones according to which a ‘collapse’ is brought about by the measurement (e.g. the traditional ‘Copenhagen’ interpretation), and the Many Worlds interpretation or interpretations—should be ruled out. The concluding section suggests some possible morals of a cosmological character. Background Scientific realism is the premise of my discussion What ‘quantum mechanics’ says—and some problems Other interpretations of quantum mechanics The problem of Einstein's bed Classification of the possible kinds of interpretation Which interpretations I think we can rule out The ‘moral’ of this discussion.

This paper reconsiders the relation between Kantian transcendental reflection (including transcendental idealism) and 20th century philosophy of science. As has been pointed out by Michael Friedman and others, the notion of a "relativized a priori" played a central role in Rudolf Carnap's, Hans Reichenbach's and other logical empiricists' thought. Thus, even though the logical empiricists dispensed with Kantian synthetic a priori judgments, they did maintain a crucial Kantian doctrine, viz., a distinction between the (transcendental) level of establishing norms for empirical (...) inquiry and the (empirical) level of norm-governed inquiry itself. Even though Thomas Kuhn's theory of scientific revolutions is often taken to be diametrically opposed to the received view of science inherited from logical empiricism, a version of this basically Kantian distinction is preserved in Kuhn's thought. In this respect, as Friedman has argued, Kuhn is closer to Carnap's theory of linguistic frameworks than, say, W.V. Quine's holistic naturalism. Kuhn, indeed, might be described as a "new Kant" in post-empiricist philosophy of science. This article examines, first, the relativization of the Kantian a priori in Reichenbach's work, arguing that while Reichenbach (after having given up his original Kantianism) criticized "transcendentalism", he nevertheless retained, in a reinterpreted form, a Kantian-like transcendental method, claiming that the task of philosophy (of science) is to discover and analyze the presuppositions underlying the applicability of conceptual systems. Then, some reflections on Kuhn's views on realism are offered, and it is suggested that Kuhn (as well as some other influential contributors to the realism debate, such as Hilary Putnam) can be reinterpreted as a (relativized, naturalized) Kantian transcendental idealist. Given the central importance of Kuhnian themes in contemporary philosophy of science, it is no exaggeration to claim that Kantian transcendental inquiry into the constitutive principles of empirical knowledge, and even transcendental idealism (as the framework for such inquiry), still have a crucial role to play in this field and deserve further scrutiny.

Grice and Strawson's 'In Defense of a Dogma is admired even by revisionist Quineans such as Putnam (1962) who should know better. The analytic/synthetic distinction they defend is distinct from that which Putnam successfully rehabilitates. Theirs is the post-positivist distinction bounding a grossly enlarged analytic. It is not, as they claim, the sanctified product of a long philosophic tradition, but the cast-off of a defunct philosophy - logical positivism. The fact that the distinction can be communally drawn does not show (...) that it is based on a real difference. Subcategories that can be grouped together by enumeration will do the trick. Quine's polemical tactic (against which Grice and Strawson protest) of questioning the intelligibility of the distinction is indeed objectionable, but his argument can be revived once it is realized that 'analytic' et al. are theoretic terms, and there is no extant theory to make sense of them. Grice and Strawson's paradigm of logical impossibility is, in fact, possible. Their attempt to define synonymy in Quinean terms is a failure, nor can they retain analyticity along with the Quinean thesis of universal revisability. The dogma, in short, is indefensible.

Different philosophers tried ways to restore the role of reason in ethics. This shift in the philosophical climate was influenced by--or was at least in accordance with--the thought of the later Wittgenstein. In particular, this article will consider the relevance of Wittgenstein for cognitivist views, such as that of S. Toulmin, relativist like G. Harman, and British moral realists like S. Lovibond and J. McDowell. In fact, Wittgenstein is one of the founding fathers of antifoundationalism. He gives us the hopeful (...) insight that the end of foundationalism does not necessarily imply the end of moral philosophy but must be considered a new start of it. (edited). (shrink)

Summary This paper is intended to discuss the problems occurring in the relation between the notion of truth and the question of self-reference. To do this, we shall review Tarski's (T) convention and its related terminology. We shall clarify the relation between truth and extension in order to lead into the question of semantic paradoxes appearing in the theoretical models concerned with truth. Subsequently, we shall review the logical system which develops in the reformulation of the modal proposal of the (...) (T) convention. In closing, we shall critically examine Kripke's interpretation from the proposals made by Tarski. (shrink)

This article examines Hilary Putnam's work in the philosophy of mathematics and - more specifically - his arguments against mathematical realism or objectivism. These include a wide range of considerations, from Gödel's incompleteness-theorem and the limits of axiomatic set-theory as formalised in the Löwenheim-Skolem proof to Wittgenstein's sceptical thoughts about rule-following, Michael Dummett's anti-realist philosophy of mathematics, and certain problems – as Putnam sees them – with the conceptual foundations of Peano arithmetic. He also adopts a thought-experimental approach – a (...) variant of Descartes' dream scenario – in order to establish the in-principle possibility that we might be deceived by the apparent self-evidence of basic arithmetical truths or that it might be ‘rational’ to doubt them under some conceivable set of circumstances. Thus Putnam assumes that mathematical realism involves a self-contradictory ‘Platonist’ idea of our somehow having quasi-perceptual epistemic ‘contact’ with truths that in their very nature transcend the utmost reach of human cognitive grasp. On this account, quite simply, ‘nothing works’ in philosophy of mathematics since wecan either cling to that unworkable notion of objective truth or abandon mathematical realism in favour of a verificationist approach that restricts the range of admissible statements to those for which we happen to possess some means of proof or ascertainment. My essay puts the case, conversely, that these hyperbolic doubts are not forced upon us but result from a false understanding of mathematical realism – a curious mixture of idealist and empiricist themes – which effectively skews the debate toward a preordained sceptical conclusion. I then go on to mount a defence of mathematical realism with reference to recent work in this field and also to indicate some problems – as I seethem – with Putnam's thought-experimental approach as well ashis use of anti-realist arguments from Dummett, Kripke, Wittgenstein, and others.

This paper presents an argument for metaphysical realism, understood as the claim that the world has structure that would exist even if our cognitive activities never did. The argument is based on the existence of a structured world at a time when it was still possible that we would never evolve. But the interpretation of its premises introduces subtleties: whether, for example, these premises are to be understood as assertions about the world or about our evidence, internally or externally, via (...) assertibility conditions or truth conditions – and what sorts of beings are included in the `we' upon whose cognitions the antirealist supposes the structure of the world to depend. I argue that antirealism can provide no defensible, fully articulated interpretation of the premises that either shows them not to be true or defeats the reasoning. (shrink)

Quine and Davidson employ proxy functions to demonstrate that the use of language (behaviouristically conceived) is compatible with indefinitely many radically different reference relations. They also believe that the use of language (behaviouristically conceived) is all that determines reference. From this they infer that reference is indeterminate, i.e. that there are no facts of the matter as to what singular terms designate and what predicates apply to. Yet referential indeterminacy yields rather dire consequences. One thus does wonder whether one can (...) hold on to a Quine--Davidson stance in semantics-cum-metaphysics and still avoid embracing referential indeterminacy. I argue that one can. Anyone adhering to the behaviouristic account pivotal to the Quine--Davidson stance is bound to acknowledge certain facts about verbal behaviour -- that some utterances are tied to situations, that some utterances are tied to segments in situations, that some predicates have non-contextualised conditions of application, and that use involves causal dependencies. The restrictions from these facts ensure that only reference relations generated by means of rather exceptional proxy functions are compatible with verbal behaviour. I conclude that this allows one to rebuff the Quine--Davidson argument for the indeterminacy of reference, as it were, from within. I moreover tentatively conclude that the line of thought laid out provides good reason for just about anyone to hold that there are facts about reference after all. (shrink)

This paper gives a critical evaluation of the philosophical presuppositions and implications of two current schools in the sociology of knowledge: the Strong Programme of Bloor and Barnes; and the Constructivism of Latour and Knorr-Cetina. Bloor's arguments for his externalist symmetry thesis (i.e., scientific beliefs must always be explained by social factors) are found to be incoherent or inconclusive. At best, they suggest a Weak Programme of the sociology of science: when theoretical preferences in a scientific community, SC, are first (...) internally explained by appealing to the evidence, e, and the standards or values, V, accepted in SC, then a sociologist may sometimes step in to explain why e and V were accepted in SC. Latour's story about the social construction of facts in scientific laboratories is found to be misleading or incredible. The idea that scientific reality is an artifact turns out to have some interesting affinities with classical pragmatism, instrumentalism, phenomenology, and internal realism. However, the constructivist account of theoretical entities in terms of negotiation and social consensus is less plausible than the alternative realist story which explains consensus by the preexistence of mind-independent real entities. The author concludes that critical scientific realism, developed with the concept of truthlikeness, is compatible with the thesis that scientific beliefs or knowledge claims may be relative to various types of cognitive and practical interests. However, the realist denies, with good reasons, the stronger type of relativism which takes reality and truth to be relative to persons, groups, or social interests. (shrink)

Words and Life (= WL) is a bulky collection of 29 essays, edited and introduced by James Conant. Pragmatism: An Open Question (= P) is a much thinner collection, dedicated to Conant, of just three lectures. Taken together, the two books constitute an argument for pragmatism as a viable option in contemporary philosophy, and a new (pragmatic) basis for what remains viable in the philosophical and political ideals of the Enlightenment. As in a previous collection of essays (Putnam 1990), Conant’s (...) role appears to be more than just editorial. In his own lengthy introductions, he gives Putnam’s work an interpretive ‘spin’, of which Putnam, for his part, seems to approve. Together, Putnam and Conant develop a strain of pragmatism which is well worth looking into.1 Putnam’s pragmatism is best captured by the quote from Cavell (1979: p. 125) which appears as the motto on the title page of the 1994 collection, and from which its title – ‘Words and Life’ – is derived. It is the view that although philosophy is an open ended practice of reflection, rather than a purely contemplative theory of one kind or another, the practice in question is at one and the same time a part of culture (immanence) and a step beyond it (transcendence). In Cavell’s language, the task of such reflection (‘philosophizing’) is ‘to confront culture with itself, along the lines in which it meets in me’, where the self in question – the individual qua philosopher – appears to be engulfed by culture even as he is confronting it from the outside. On this interpretation, Putnam’s appeal to practice in philosophy is part of an attempt to keep its transcendent, or critical, dimension alive, even while recognizing philosophy’s radical embeddedness in culture and tradition, and the futility of seeking some God’s-eye view from which reality as such is to be viewed.2 The question is whether, and how, these two perspectives can be held together. If our standards of rational criticism transcend any particular culture in terms of their scope and authority, how can they also be embedded in culture and immanent to it? Can pragmatism offer a coherent synthesis of these two dimensions.. (shrink)

On a widespread naturalist view, the meanings of mathematical terms are determined, and can only be determined, by the way we use mathematical language—in particular, by the basic mathematical principles we’re disposed to accept. But it’s mysterious how this can be so, since, as is well known, minimally strong first-order theories are non-categorical and so are compatible with countless non-isomorphic interpretations. As for second-order theories: though they typically enjoy categoricity results—for instance, Dedekind’s categoricity theorem for second-order PA and Zermelo’s quasi-categoricity (...) theorem for second-order ZFC—these results require full second-order logic. So appealing to these results seems only to push the problem back, since the principles of second-order logic are themselves non-categorical: those principles are compatible with restricted interpretations of the second-order quantifiers on which Dedekind’s and Zermelo’s results are no longer available. In this paper, we provide a naturalist-friendly, non-revisionary solution to an analogous but seemingly more basic problem—Carnap’s Categoricity Problem for propositional and first-order logic—and show that our solution generalizes, giving us full second-order logic and thereby securing the categoricity or quasi-categoricity of second-order mathematical theories. Briefly, the first-order quantifiers have their intended interpretation, we claim, because we’re disposed to follow the quantifier rules in an open-ended way. As we show, given this open-endedness, the interpretation of the quantifiers must be permutation-invariant and so, by a theorem recently proved by Bonnay and Westerståhl, must be the standard interpretation. Analogously for the second-order case: we prove, by generalizing Bonnay and Westerståhl’s theorem, that the permutation invariance of the interpretation of the second-order quantifiers, guaranteed once again by the open-endedness of our inferential dispositions, suffices to yield full second-order logic.

The most basic divide amongst analytic metaphysicians separates realists from anti-realists. By examining certain characteristic and problematic features of these two families of views, we uncover their underlying metametaphysicalorientations, which turn out to coincide. This shared philosophical picture that underlies both the realist and the anti-realist project we call the Modern Picture. It rests on a crucial distinction between reality as it is for us and reality as it is in itself. It is argued that this distinction indeed generates the (...) realism/anti-realism dichotomy, and is also responsible for the problematic aspects highlighted earlier. We conclude by sketching an alternative philosophical picture that rejects the distinction between reality as it is for us and reality as it is in itself, which we call the Aristotelian Picture, and consider whether it is able to avoid the issues to which the Modern Picture gives rise.

A basic theme of Winograd and Flores (1986) is that the principal function of language is to co-ordinate social activity. It is, they claim, from this function that meaning itself arises. They criticise approaches that try to understand meaning through the mechanisms of reference, the Rationalist Tradition as they call it. To seek to ground meaning in social practice is not new, but the approach is presently attractive because of difficulties encountered with the notion of reference. Without taking a view (...) on whether these are insuperable, the present paper accepts Winograd and Flores'' challenge and attempts to lay aside reference and to base a conception of meaning directly in terms of co-ordination and consensus within a linguistic community.

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)
