The paper deals with Hilary Putnam's model-theoretic argument against metaphysical realism. It considers the objections to the argument raised by David Lewis, Mark Heller, James van Cleve, Anthony Brueckner and others, to the effect that Putnam's reasoning fails to undermine versions of metaphysical realism which construe reference along externalist lines. I argue that the version of Putnam's argument that his critics have attacked is indeed powerless against externalist accounts of reference, but that, on a different construal, the argument puts genuine (...) pressure on externalism. On the version of the argument that I develop, the thrust of the model-theoretic considerations is that an externalist construal of reference would make grasp of reference facts impossible. (shrink)

Since Hilary Putnam and Saul Kripke's first attacks on traditional, descriptivist theories of natural kind terms, it has become customary to speak of the ‘Putnam-Kripke’ view of meaning and reference. This article argues that this is a mistake, and that Putnam's account of natural kind terms is importantly different from that of Kripke. In particular, Putnam has from the very start been sceptical of Kripke's modal claims, and in later papers he explicitly rejects the proposal that theoretical identity statements are (...) metaphysically necessary (if true). I suggest that this is wholly in line with Putnam's earlier, Quine-inspired writings on general terms, and his preoccupation with the philosophy of science. Moreover, I argue that the picture of general terms that emerges from Putnam's writings is more plausible than that suggested by Kripke. However, contrary to Putnam, I also suggest that Putnam's later views on natural kinds and natural kind terms do not support standard Twin Earth externalism. (shrink)

Recent discussions in cognitive science and the philosophy of mind have defended a theory according to which we live in a virtual world akin to a computer simulation, generated by our brain. It is argued that our brain creates a model world from a variety of stimuli; this model is perceived as if it was external and perception-independent, even though it is neither of the two. The view of the mind, brain, and world, entailed by this theory has some peculiar (...) consequences which have rarely been explored in detail. This paper sets out virtual world theory and relates it to various central philosophical problems, the role of the perceiver and the problem of the existence of the external world ). The second part suggests three interpretations of virtual world theory, two familiar ones and a somewhat less familiar one. The remainder of the paper argues that the irrealist interpretation is the one we should adopt. (shrink)

According to the anti-Humean theory of motivation, it is possible to be motivated to act by reason alone. According to the Humean theory of motivation, this is impossible. The debate between these two theories remains as vigorous as ever (see for example Pettit 1987, Lewis 1988, Price 1989 and Smith 1994). In this paper I shall argue that the anti-Humean theory of motivation is incompatible with a number of prominent recent theories of content. I shall focus on causal or informational (...) theories of content (such as Dretske 1981, Fodor 1990 and Stalnaker 1984), and on verificationist theories of content (such as Dummett 1993, Putnam 1983 and Wright 1986), though in fact I believe that the same argument applies to several other theories of content as well.

There is a widespread opinion that the realist idea that whether a proposition is true or false typically depends on how things are independently of ourselves is bound to turn truth, in Davidson's words, into “something to which humans can never legitimately aspire”. This opinion accounts for the ongoing popularity of “epistemic” theories of truth, that is, of those theories that explain what it is for a proposition (or statement, or sentence, or what have you) to be true or false (...) in terms of some epistemic notion, such as provability, justifiability, verifiability, rational acceptability, warranted assertibility, and so forth, in some suitably characterized epistemic situation. My aim in this paper is to show that the widespread opinion is erroneous and that the (legitimate) epistemological preoccupation with the accessibility of truth does not warrant the rejection of the realist intuition that truth is, at least for certain types of propositions, radically nonepistemic.

In the 1960s and 1970s, Hilary Putnam articulated a notion of relativized apriority that was motivated to address the problem of scientific change. This paper examines Putnam’s account in its historical context and in relation to contemporary views. I begin by locating Putnam’s analysis in the historical context of Quine’s rejection of apriority, presenting Putnam as a sympathetic commentator on Quine. Subsequently, I explicate Putnam’s positive account of apriority, focusing on his analysis of the history of physics and geometry. In (...) the remainder of the paper, I explore connections between Putnam’s account of relativized a priori principles and contemporary views. In particular, I situate Putnam’s account in relation to analyses advanced by Michael Friedman, David Stump, and William Wimsatt. From this comparison, I address issues concerning whether a priori scientific principles are appropriately characterized as “constitutive” or “entrenched”. I argue that these two features need to be clearly distinguished, and that only the constitutive function is essential to apriority. By way of conclusion, I explore the relationship between the constitutive function of a priori principles and entrenchment. (shrink)

The pragmatist faces the challenge of accounting for the possibility of rational conceptual change. Some pragmatists have tried to meet this challenge by appealing to Neurathian imagery—imagery that risks being too figurative to be helpful. I argue that we can develop a clearer view of what rationally constrained conceptual revision looks like for the pragmatist. I do so by examining the work of the pragmatist who in recent years has addressed this issue most directly, Richard Rorty. His attempts to solve (...) the puzzle ultimately fall short, but prove instructive. Rorty characterizes inter-language transitions in exclusively causal terms because, along with the very philosophical traditions he criticizes, he uncritically privileges the role of truth claims or assertions in our pragmatics. I show that if we instead broaden our pragmatic imaginations, we encounter various non-assertoric speech acts involved in speakers aiming to change how we make sense of our language and concepts. With these acts in view, we are able to arrive at a demystified view of rational conceptual change from a pragmatist perspective and identify future lines of inquiry for pragmatist projects.

We review the decoherent histories approach to the interpretation of quantum mechanics. The Everett relative-state theory is reformulated in terms of decoherent histories. A model of evolutionary adaptation is shown to imply decoherence. A general interpretative framework is proposed: probability and value-definiteness are to have a similar status to the attribution of tense in classical spacetime theory.

In this paper I distinguish two ways of using the expression ‘epistemological naturalism’. In one sense, naturalism amounts to a denial that epistemology should be understood as a kind of first philosophy providing the foundations for science from outside. In a second sense, naturalism holds that human knowledge is a natural phenomenon and that epistemology should be seen as a chapter of natural science. Moreover, naturalism in this second sense usually incorporates some additional specifications that build up a very restrictive (...) concept of science. Two different projects for naturalizing epistemology lie behind these two meanings of ‘naturalism’, and the two projects, although sometimes seen as complementary or even equivalent, are not necessarily so. After drawing this distinction, I set out the difficulties faced by those naturalistic stances that do not discriminate sharply enough or do not establish the appropriate hierarchical relationship between both projects. Finally, I argue for a conception of epistemology which is best described as a radical antilfoundntionnlism. This conception sticks to the requirements that follow from naturalism when understood in the first sense above, and takes the cluster of theses that give birth to the second as subsidiary and revisable.

The paper argues that the reference of perceptual demonstratives is fixed in a causal nondescriptive way through the nonconceptual content of perception. That content consists first in spatiotemporal information establishing the existence of a separate persistent object retrieved from a visual scene by the perceptual object segmentation processes that open an object-file for that object. Nonconceptual content also consists in other transducable information, that is, information that is retrieved directly in a bottom-up way from the scene (motion, shape, etc). The (...) nonconceptual content of the mental states induced when one uses a perceptual demonstrative constitutes the mode of presentation of the perceptual demonstrative that individuates but does not identify the object of perceptual awareness and allows reference to it. On that account, perceptual demonstratives put us in a de re relationship with objects in the world through the non-conceptual information retrieved directly from the objects in the environment.

In "Sider on Existence" (Noužs, 2007), David Liebesman and Matti Eklund argue that my "indeterminacy argument", according to which quantifiers are never vague, clashes with my "naturalness argument", according to which quantifiers "carve at the joints". There is, I argue, no outright inconsistency. But Liebesman and Eklund have shown that my arguments are not as independent as it may have appeared. The best defense of the indeterminacy argument is via the naturalness argument.

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)

There have been attempts to derive anti-haeccetistic conclusions from the fact that quantum mechanics (QM) appeals to non-standard statistics. Since in fact QM acknowledges two kinds of such statistics, Bose-Einstein and Fermi-Dirac, I argue that we could in the same vein derive the sharper anti-haeccetistic conclusion that bosons are bundles of tropes and fermions are bundles of universals. Moreover, since standard statistics is still appropriate at the macrolevel, we could also venture to say that no anti-haecceitistic conclusion is warranted for (...) ordinary objects, which could then tentatively be identified with substrates. In contrast to this, however, there has been so far no acknowledgement of the possibility of inclusivism, according to which ontological accounts of particulars as widely different as those can possibly coexist in one world picture. The success of the different statistics in physics at least calls for a revision in this respect. (shrink)

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.

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.

Metaontology – the study of the nature of ontological issues – has flourished in recent years. The focus of this summary will be on some views and arguments that are central to today’s debate. One theme will be that of how seriously to take ontology: whether there is reason to take a skeptical or deflationary attitude toward ontological claims, as theorists like Rudolf Carnap, Hilary Putnam, and Eli Hirsch in different ways have urged. The other theme will be that of (...) the viability of the Fregean and Quinean approaches to ontology that have been and still are central to analytic philosophy. (shrink)

Hilary Putnam's philosophical views have undergone extensive interpretation over many years. One such interpretive work is George Myerson's book Rhetoric, Reason and Society. Myerson's interest in dialogic rationalism leads him to examine the views of many theorists of rationality, philosophers and non-philosophers alike. As a prominent philosopher of rationality, Putnam is at the very center of this examination. Notwithstanding this fact, I contend that Myerson misinterprets the dialectical character of Putnam's philosophy in general and of Putnam's views on rationality in (...) particular. This misinterpretation, I argue, is revealing of an illusion of thought to which Myerson is subject, an illusion that makes it seem that it is possible to theorize intelligibly about rationality from a metaphysical standpoint. This same illusion, I claim, also makes it seem that Myerson's positive views on rationality are intelligible. Employing a close textual analysis of Myerson's book, I argue that neither scenario is the case. (shrink)

In (2001), (2003), and elsewhere, Ted Sider presents two arguments concerning the existential quantifier which are justly central to the recent discussion of metaontology. What we will call Sider's indeterminacy argument is an attempted reductio of the suggestion that the existential quantifier might be semantically indeterminate. What we will call Sider's naturalness argument is an argument for the claim that the semantic value of the existential quantifier is the most eligible existence-like meaning there is, à la David Lewis' eligibility theory (...) of meaning. We will argue that these arguments cannot be jointly maintained: Sider must give up at least one. Before arguing this, we will present Sider's two arguments in a bit more detail, and discuss their relationship. A few remarks on the broader significance of our conclusions are in order at the outset. One may think that since one successful argument for a given conclusion is sufficient the point that Sider's arguments cannot both work is purely academic. But we think that Sider's two arguments at bottom reflect different ways of thinking about metaphysics. Moreover, we think that it is only the naturalness argument that promises to deliver all that Sider wants when it comes to metaontology, and it is only the indeterminacy argument that promises to deliver all that Sider wants when it comes to ontology.

Rationalism in political philosophy is the view that politics should be governed by moral principles and that those principles can and should be justified independently of the situations and circumstances that make up political reality. This traditional view of political philosophy implies that the meaning of right political action is determined by moral principles the rational authority of which derives from abstract philosophical reasoning, not from the situations and circumstances that are the substance of political reality. In this essay I (...) argue that rationalist moralities must presuppose the understanding of particular situations and circumstances for their meaningful and correct interpretation. This means, I argue, that the rightness of political judgement and action is immanent in particular situations, not in abstract moralities. And this, I argue, suggests a shift from the traditional view of political society as the embodiment of abstract principles, towards a view of political society as the embodiment of the activity of situational judgement. A society worth hoping for, then, is one in which we can live in the light of our understanding of the situations and circumstances that are the substance of everyday life, rather than in the shadow of abstract moralities. Such a society would be sensitive to the particularities and complexities of political reality, but at the same time it does not succumb to moral relativism and skepticism. (shrink)

David Lewis is associated with the controversial thesis that some properties are more eligible than others to be the referents of our predicates solely in virtue of those properties’ being more natural; independently, that is, of anything to do with our patterns of usage of the relevant predicates. On such a view, the natural properties act as ‘reference magnets’. In this paper I explore (though I do not endorse) a related thesis in epistemology: that some propositions are ‘justification magnets’. According (...) to the doctrine of justification magnetism, we have better justification for some propositions than for others solely in virtue of certain features of those propositions; independently, that is, of anything to do with evidential support or cognitive accomplishment. In the course of discussing an objection to justification magnetism I describe (though I do not endorse) a novel approach to epistemology akin to interpretationism in the theory of reference.

For most of the major philosophers of the seventeenth and eighteenth centuries, human cognition was understood as involving the mind’s reflexive grasp of its own contents. But other important figures have described the very idea of a reflexive thought as incoherent. Ryle notably likened the idea of a reflexive thought to an arm that grasps itself. Recent work in philosophy, psychology, and the cognitive sciences has greatly clarified the special epistemic and semantic properties of reflexive thought. This article is an (...) attempt to give an explicit characterization of the structure of reflexive thoughts that explains those properties and avoids the complaints of its critics. (shrink)

I argue for three principle claims. First, philosophers who seek to integrate the semantic and the intentional into a naturalistic metaphysical worldview need to address a task that they have thus far largely failed even to notice: explaining into- level connections between the physical and the intentional in a naturalistically acceptable way. Second, there are serious reasons to think that this task cannot be carried out in a way that would vindicate realism about intentionality. Third, there is much to be (...) said for an irrealist, non-eliminativist, naturalistic approach to intentionality that I call "preservative irrealism". (shrink)

How can philosophy exert its critical function in society and in education if any appeal to independent and even relatively ‘certain’ criteria seems problematic? The epistemological doubts that foundationalist models of justification encounter unavoidably seem to raise this question. In particular, the relativist implications that seem to result from rejecting such models seem to paralyse the critical potential of philosophy of education. In order to explore the possibilities of a conception of educational critique that avoids the pitfalls of foundationalism, I (...) analyse the epistemological dimensions of this much-feared relativism, illustrating this with some characteristic examples. Solving the problems raised will require an interpretation of critique that leaves our daily sense of critique intact, without literally adopting its—foundationalist—basic assumptions. After systematically developing such an alternative interpretation of critical usage, a non-relativist but still non-foundationalist and powerful conception of philosophical critique seems possible. I illustrate results with some examples from philosophy of education. (shrink)

A conception of social epistemology is articulated with links to studies of science and opinion in such disciplines as history, sociology, and political science. The conception is evaluative, though, rather than purely descriptive. Three types of evaluative approaches are examined but rejected: relativism, consensualism, and expertism. A fourth, truth-linked, approach to intellectual evaluation is then advocated: social procedures should be appraised by their propensity to foster true belief. Standards of evaluation in social epistemics would be much the same as those (...) in individual epistemics, only the objects of evaluation would be interpersonal patterns of judgment and communication, and institutional practices that bear on opinion formation.

ABSTRACTThis article argues that Quine's holistic and naturalized semantics provides an inadequate account of the foundations of logical expressions and misrepresents the internal structure of theories. By considering a Quinean model of theoretical revision, I identify the status and foundation holism provides to the propositions of logic. I contend that a central tenet of Quinean holism—the Revisability Doctrine—cannot be held consistently, and that the inconsistencies surrounding it mark a series of pervasive errors within naturalized holism. In response, I propose that (...) semantic theories must reflect the different linguistic functions of different types of expressions and the specific relationships that individual concepts within a theory or language have to one another.

This paper gives a new twist to already familia refutations of Putnam's "model-theoretic" argument against realism. Recent attempts to defend the model-theoretic argument in the face of those criticisms indicate that the main point of previous rebuttals of the argument can be easily missed. The paper expounds the same point again in a different guise, by having recourse to ideas on models and the model-theoretic account of the logical properties developed by the author in earlier work. Some writers appear to (...) think that the charge of previous criticisms is that Putnam's argument begs the question, by involving as premise a proposition which all too obviously entails the falsity of realism--precisely what the argument is designed to establish. They then defend it by claiming that Putnam does not simply _take for granted<D> the truth of the offending premise, but _argues for<D> it. This, however, does not defend Putnam's argument against the _pragmatic<D> charges of irrelevancy and potential for provoking confusion--which, the paper shows, can be taken as the main criticisms levelled against it by previous writers. The point is that, if Putnam has an independent argument for the question-begging premise, one not involving any model-theoretic considerations, then this is all that is needed; the specifically model-theoretic considerations are irrelevant and could lead to spurious debates.

Putnam's Model-Theoretic argument purports to show that, contrary to what the metaphysical realist is committed to, an epistemically ideal theory which satisfies all operational and theoretical constraints can be guaranteed to be true. He draws the additional antirealist conclusion that there can be no single privileged relation of reference. I argue that the very possibility of a so-called ideal theory satisfying all operational constraints presupposes a determinate relation of reference, and hence Putnam must assume precisely what he denies.

There are several distinct components of the realist anti-realist debate. Since each side in the debate has its disadvantages, it is tempting to try to combine realist theses with anti-realist theses in order to obtain a better, more moderate position. Putnam attempts to hold a realist concept of truth, yet he rejects realist metaphysics and realist semantics. He calls this view internal realism. Truth is realist on this picture for it is objective, rather than merely intersubjective, and eternal. Putnam introduces (...) a concept of epistemic idealization — epistemically ideal conditions, or idealized justification — to try to ground the strong objectivity of truth without sliding into metaphysical realism. I argue that the concept of ideal conditions to which Putnam appeals does not cohere with his (anti-realist) commitment to an assertability conditions account of meaning. (shrink)

Realism, defined as a justified belief in the existence of the external world, is jeopardized by ‘meaning rationalism,’ the classic theory of meaning that sees the extension of words as a function of the intensions of individual speakers, with no way to ensure that these intensions actually correspond to anything in the external world. To defend realism, Ruth Millikan ( 1984 , 1989a , b , 1993 , 2004 , 2005 ) offers a biological theory of meaning called ‘teleosemantics’ in (...) which words, without requiring any contribution from the speaker’s intensions, are supposedly matched directly with their extensions by external norms. But even if one granted as a theoretical possibility that word meaning might possibly be stabilized through an external process, nonetheless, realists who wish to appeal to teleosemantics for a semantic proof of the external world must be capable of identifying these external norms, something that Millikan describes as highly fallible. Furthermore, because they can be aware of these norms only as these are internally represented, it would also be necessary for realists to verify that these internal representations accurately reflect the norms as they occur in the external world. But given that this is virtually the same stumbling block to realism found in meaning rationalism, it is concluded that teleosemantics is not likely to restore faith in this worldview. (shrink)

I present and defend a unified, non-reductive analysis of the a priori and a posteriori. It is a mistake to remove all epistemic conditions from the analysis of the a priori (as, for example, Alvin Goldman has recently suggested doing). We can keep epistemic conditions (like unrevisability) in the analysis as long as we insist that a priori and a posteriori justification admit of degrees. I recommend making the degree to which a belief’s justification is a priori or a posteriori (...) solely dependent on the revisability relations that obtain among the faculties that deliver the belief and all other faculties.

Colin McGinn proposes that acceptance of the supervenience of the modal on the actual is the natural form of expression of a non-objectual realism about modality. Here, some of the difficulties that arise in applying theses of supervenience to the modal-actual case are discussed. It is then argued: 1)that the truth of many such theses is determined on uncontroversial modal logical and conceptual grounds, and 2) that this and other independent considerations render it highly implausible that the affirmation of modal-actual (...) supervenience amounts to a modal realism.
