ABSTRACT Massimo Dell’Utri proposes the idea of an ‘epistemological compass’, which he alleges provides a common intuitive sense of objectivity, the existence of which defenders of ‘post-truth’ positions would perversely try to deny. I argue that Dell’Utri’s choice of a compass – metaphorical or otherwise – is unfortunate because it is a device that presupposes that what appears plain to the senses is directed by hidden forces emanating from distant sources, such as the stars. More generally, the post-truth condition is (...) not about the denial of facts as ordinarily understood. Rather, it is about the denial of a privileged context in terms of which the significance of the facts should be understood. In Dell’Utri’s terms, it implies a plurality of epistemological compasses, which in turn undermines the effectiveness of the metaphor. I have described this situation as a struggle over ‘the name of the game’. In terms of philosophical logic, it is about which metalanguage provides the semantics for expressions in the object language the people try to deploy to their advantage. (shrink)

Richard Rorty is easily cast as the intellectual godfather of our post-truth condition. But unlike Nicholas Gaskill, whose article in Common Knowledge 28, no. 3, has engendered a continuing symposium in the journal, Professor Fuller sees Rorty's role as being to his credit rather than detriment. Rorty extended W. B. Gallie's idea of “essentially contested concepts” from the moral and political spheres to the epistemic, thereby rendering such terms as truth, reason, and evidence inherently vague, which means that they are (...) defined not a priori but only in the context of exemplary concrete cases. Doing so invariably results in a “redescription” of what is observed that explains the “meta” level of understanding that philosophy brings to whatever it discusses. In this sense, all that the post-truth condition does is turn everyone into a philosopher. (shrink)

In his book, The Scientific Image, van Fraassen lucidly draws an alternative to scientific realism, which he calls "Constructive Empiricism". In this epistemological theory, the concept of observability plays the pivotal role: acceptable theories may be believed only where what they say solely concerns observables. Van Fraassen develops a concept of observability which is, as he admits, vague, relative, science-dependent, and anthropocentric. I draw out unacceptable consequences of each of these aspects of his concept. Also, I argue against his assumption (...) that "empirical adequacy" is the same thing as "saving the phenomena", according to his sense of the expressions. (shrink)

Several arguments are considered which purport to demonstrate the impossibility of theory-neutral observation. The most important of these infers the continuity of observation with theory from the presumed continuity of perception with cognition, a doctrine widely espoused in recent cognitive psychology. An alternative psychological account of the relation between cognition and perception is proposed and its epistemological consequences for the observation/theory distinction are then explored.

I critically evaluate Bickle’s version of scientific theory reduction. I press three main points. First, a small point, Bickle modifies the new wave account of reduction developed by Paul Churchland and Clifford Hooker by treating theories as set-theoretic structures. But that structuralist gloss seems to lose what was distinctive about the Churchland-Hooker account, namely, that a corrected theory must be specified entirely by terms and concepts drawn from the basic reducing theory. Set-theoretic structures are not terms or concepts but the (...) structures that they describe. Second, and more serious, a familiar problem for classical positivist account of reduction resurfaces within this newest wave of thinking, namely, commitment to property identities and inter-theoretic bridge laws (a problem I discussed at more length in "Collapse of the New Wave"). Indeed, this problem is exacerbated by Bickle’s conciliatory treatment of property plasticity, since he is willing to grant that a large number of special science terms denote multiply realized properties, at least if realistically construed. Still, in the end, Bickle sidesteps the reduction of properties by appealing to Hooker’s "function-to-structure token reduction." This is an interesting move with an intriguing concept of reduction. But problems remain. For, third, Bickle and Hooker's function-to-structure token reduction is actually a guised form of eliminative materialism. But that should be unacceptable since the position extends well beyond any modest revisionism for suspect items from a folk theory, say, in folk psychology or folk biology. Instead, it applies to functional terms and concepts employed throughout well-developed and explanatorily successful sciences. (shrink)

A theory of information is developed in which the informational content of a signal (structure, event) can be specified. This content is expressed by a sentence describing the condition at a source on which the properties of a signal depend in some lawful way. Information, as so defined, though perfectly objective, has the kind of semantic property (intentionality) that seems to be needed for an analysis of cognition. Perceptual knowledge is an information-dependent internal state with a content corresponding to the (...) information producing it. This picture of knowledge captures most of what makes knowledge an important cpistcmological notion. It also avoids many of the problems infecting traditional justificational accounts of knowledge (knowledge as [justified, true belief those (unlike knowledge) having a content that can be either true or false (e.g., belief) – are described in terms of the way internal (presumably neural) structures acquire during learning a certain information-carrying role. The content of these structures (whether true or false) is identified with the kind of information they were developed to carry. (shrink)

Most philosophical accounts of the foundations of economics have assumed that economics is intended to be an empirical science concerned with human behaviour, though they have, of course, differed over the extent to which it has been or can be successful as such an enterprise. A prominent source of dissent against this consensus is Alexander Rosenberg. In his recent book, Rosenberg summarizes and completes his statement of a position that he has been developing for some time. He argues that although (...) economists evaluate one another's work according to shared and rigorous standards of adequacy, these standards are strictly internal, like those of mathematics, instead of being derived from discoveries about contingent relationships between theoretical statements and empirical facts. Economics, that is to say, is essentially conceptual rather than empirical inquiry. In the following discussion, I will provide grounds for resisting Rosenberg's conclusion. The point of this criticism, however, is not mainly negative. Most of the historical preoccupations of the philosophy of economics, like those of the philosophy of science in general, have been epistemological. Careful attention to Rosenberg's argument, however, redirects our attention to ontological questions about the objects of economics, and this redirection, I will maintain, is to be welcomed. I will argue that while the majority of philosophers of economics is correct, as against Rosenberg, in regarding economics as an empirical science, the conventional view as to the identity of its empirical objects should be substantially revised under the pressure of Rosenberg's criticisms. My critical analysis of the implications of Rosenberg's work for the ontological commitments of economics is intended to furnish one line of argument towards my own conception of the objects of economics. This conception, which is still preliminary in many respects, will be briefly sketched toward the end of the present paper; a detailed account of it is given in Ross and LaCasse. (shrink)

A novel semantic naturalization program is proposed. Its three main differences from informational semantics approaches are as follows. First, it makes use of a perceptually based, four-factor interactive causal relation in place of a simple nomic covariance relation. Second, it does not attempt to globally naturalize all semantic concepts, but instead it appeals to a broadly realist interpretation of natural science, in which the concept of propositional truth is off-limits to naturalization attempts. And third, it treats all semantic concepts as (...) being purely abstract, so that concrete cognitive states are only indexed by them rather than instantiating them. (shrink)

The issue of realism about the physical world is distinct from the semantic issue of correspondence truth. So it is an aberration to identify the two issues (Dummett), to dismiss the realism issue out of hostility to correspondence truth (Rorty, Fine), to think that that issue is one of interpretation, or to argue against realism by criticizing various claims about truth and reference (Putnam, Laudan). It is also an aberration to identify realism with nonskepticism, truth-as-the-aim-of-science, or scientific convergence. Realism is (...) an overarching metaphysical issue which should be settled before any of these epistemic and semantic issues. (shrink)

Le problème métaphysique central en philosophie de l’esprit concerne la relation entre l’esprit et le corps des agents. Quand on tente d’expliquer, par exemple, le rapport entre les pensées et les actions humaines, on est alors immédiatement confronté avec la difficulté, apparemment insurmontable, d’expliquer la causalité mentale. On doit répondre à la question : nos états de pensée causent-ils effectivement ce que l’on fait? Bien sûr, nos croyances, nos intentions et nos désirs sont à la base de notre comportement, dira (...) le sens commun et une longue tradition philosophique. Cependant, certains philosophes ont récemment manifesté des doutes à propos du rôle réel de nos pensées sur nos actions. Pour contrer ce scepticisme, il nous faut expliquer comment des états de pensée peuvent exercer leur rôle causal dans un monde fondamentalement physique. Je vais donner ici les raisons pour lesquelles je crois que les états de pensée sont indispensables à l’explication complète de nos actions. Pour ce faire, je procéderai à une analyse approfondie de la relation entre la causalité mentale ou intentionnelle et la causalité physique. Je mettrai en perspective deux approches importantes sur la causalité mentale : celle de John Searle, qui défend la réalité des états mentaux et semble résister au réductionnisme, et celle de Jaegwon Kim, qui montre le péril auquel l’approche de Searle est exposée : la surdétermination causale! Selon Searle, le mental est un trait du monde physique . Aux yeux de Kim cette stratification en niveaux n’apporte aucune solution au problème de la causalité mentale. Kim a-t-il raison? (shrink)

Scientific realism is the position that the aim of science is to advance on truth and increase knowledge about observable and unobservable aspects of the mind-independent world which we inhabit. This book articulates and defends that position. In presenting a clear formulation and addressing the major arguments for scientific realism Sankey appeals to philosophers beyond the community of, typically Anglo-American, analytic philosophers of science to appreciate and understand the doctrine. The book emphasizes the epistemological aspects of scientific realism and contains (...) an original solution to the problem of induction that rests on an appeal to the principle of uniformity of nature.

Steve Stich used to be an eliminativist. As far as I can tell, he renounced eliminativism about the time that he moved from the west to the east pole.1 Stich was right to reject eliminativism, though I am not convinced that he rejected it for the right reasons. Stich 1983 contains a comprehensive attack on representational content, a central feature of both folk psychology and the Representational Theory of Mind, the leading philosophical construal of scientific psychology. Stich’s current position on (...) the role of content in psychological explanation is not entirely clear. One of my aims in this chapter is simply to invite Stich to clarify his views on representational content; the question that forms the title of this chapter is therefore addressed directly to Stich. I begin by sketching his original anti-content argument. I then trace some later developments in his thinking about content. I argue that content does play an important role in scientific psychology, for precisely the reasons that Stich identified in his original argument against content. I conclude with some general remarks on eliminativism. (shrink)

Many philosophers and cognitive scientists claim that our everyday or "folk" understanding of mental states constitutes a theory of mind. That theory is widely called "folk psychology" (sometimes "commonsense" psychology). The terms in which folk psychology is couched are the familiar ones of "belief" and "desire", "hunger", "pain" and so forth. According to many theorists, folk psychology plays a central role in our capacity to predict and explain the behavior of ourselves and others. However, the nature and status of folk (...) psychology remains controversial. (shrink)

The past decade or so has witnessed an increase in the number of philosophical discussions about emergence and reduction in science. However, many of these discussions (though not all) remain too abstract and theoretical, and are wanting with respect to concrete examples taken from the sciences. This dissertation studies the topics of reduction and emergence in the context of a case study. I focus on the case of chemistry and investigate how emergentism can help us secure the autonomy of this (...) discipline in relation to the underlying microphysics. I develop an account of emergence (called functional emergence) that is, I argue, capable of answering the question of why we have chemistry instead of just applied quantum mechanics. I argue that functionally emergent properties in chemistry -- properties that are defined by their behaviour, not by some shared microphysical constituent -- can help us defend the autonomy of chemistry; they allow for the existence of sui generis chemical regularities, which can be used in sui generis chemical explanations. Functional emergence generates difficulties for some accounts of inter-theoretic reduction, but unlike other theories of emergence it is compatible with weaker forms of reductionism. (shrink)

This paper discusses a number of basic strategies for modeling the mind in historical perspective. The best-known strategies are expansionism and eliminativism, which are both problematic: eliminativism compromises our self-understanding, while expansionism is unable to cope with fringe minds. Using Julian Jaynes’s theory of the bicameral mind as an example, an alternative strategy is outlined to meet the challenges posed by the history of the mind.

The received view about emergence and reduction is that they are incompatible categories. I argue in this paper that, contrary to the received view, emergence and reduction can hold together. To support this thesis, I focus attention on dynamical systems and, on the basis of a general representation theorem, I argue that, as far as these systems are concerned, the emulation relationship is sufficient for reduction (intuitively, a dynamical system DS1 emulates a second dynamical system DS2 when DS1 exactly reproduces (...) the whole dynamics of DS2). This representational view of reduction, contrary to the standard deductivist one, is compatible with the existence of structural properties of the reduced system that are not also properties of the reducing one. Therefore, under this view, by no means are reduction and emergence incompatible categories but, rather, complementary ones. (shrink)

This paper draws upon the works of Wilfred Sellars, Jerry Fodor, and Ruth Millikan to argue against epistemological holism and conceptual holism. In the first section, I content that contrary to confirmation holism, there are individual beliefs ("basic beliefs") that receive nondoxastic/noninferential warrant. In the earliest stages of cognitive development, modular processes produce basic beliefs about how things are. The disadvantage of this type of basic belief is that the person may possess information that should have defeated the belief but (...) that was not taken into account in the module's operations. For this reason, at more advanced stages of cognitive development, basic beliefs concern how things appear to be. These appearance beliefs are not formed holistically but should be checked against background beliefs before the person infers how things are. In the second section, I argue against functional-role/inferential-role semantics. Championing teleosemantics, I argue that many concepts' meanings are not determined by the meanings of other concepts. Rather, many concepts are skills of knowing how to identify of what the concept is. These skills can be developed independently of other beliefs or skills and are, in an important sense, theory-neutral. (shrink)

This paper explores early Australasian philosophy in some detail. Two approaches have dominated Western philosophy in Australia: idealism and materialism. Idealism was prevalent between the 1880s and the 1930s, but dissipated thereafter. Idealism in Australia often reflected Kantian themes, but it also reflected the revival of interest in Hegel through the work of ‘absolute idealists’ such as T. H. Green, F. H. Bradley, and Henry Jones. A number of the early New Zealand philosophers were also educated in the idealist tradition (...) and were influential in their communities, but produced relatively little. In Australia, materialism gained prominence through the work of John Anderson, who arrived in Australia in 1927, and continues to be influential. John Anderson had been a student of Henry Jones, who might therefore be said to have influenced both main strands of Australian philosophical thought. (shrink)

Zombies are hypothetical creatures of the sort that philosophers have been known to cherish. A zombie is physically identical to a normal human being, but completely lacks conscious experience. Zombies look and behave like the conscious beings that we know and love, but "all is dark inside." There is nothing it is like to be a zombie.

The thesis proposes, defends, and applies a new model of inter-theoretic reduction, called "Neo-Nagelian" reduction. There are numerous accounts of inter-theoretic reduction in the philosophy of science literature but the most well-known and widely-discussed is the Nagelian one. In the thesis I identify various kinds of problems which the Nagelian model faces. Whilst some of these can be resolved, pressing ones remain. In lieu of the Nagelian model, other models of inter-theoretic reduction have been proposed, chief amongst which are so-called (...) "New Wave" models. I show these to be no more adequate than the original Nagelian model. I propose a new model of inter-theoretic reduction, Neo-Nagelian reduction. This model is structurally similar to the Nagelian one, but differs in substantive ways. In particular I argue that it avoids the problems pertaining to both the Nagelian and New Wave models. Multiple realizability looms large in discussions about reduction: it is claimed that multiply realizable properties frustrate the reduction of one theory to another in various ways. I consider these arguments and show that they do not undermine the Neo-Nagelian of reduction of one theory to another. Finally, I apply the model to statistical mechanics. Statistical mechanics is taken to be a reductionist enterprise: one of the aims of statistical mechanics is to reduce thermodynamics. Without an adequate model of inter-theoretic reduction one cannot assess whether it succeeds; I use the Neo-Nagelian model to critically discuss whether it does. Specifically, I consider two very recent derivations of the Second Law of thermodynamics, one from Boltzmannian classical statistical mechanics and another from quantum statistical mechanics. I argue that they are partially successful, and that each makes for a promising line of future research. (shrink)

There occurred in the twentieth century the most remarkable episode in the history of human thought. A number of thinkers denied the existence of something we know with certainty to exist: consciousness, conscious experience. Others held back from the Denial, as we may call it, but claimed that it might be true --a claim no less remarkable than the Denial. This paper documents some aspects of this episode, with particular reference to two things. First, the development of two views which (...) are forms of the Denial --philosophical behaviourism, and functionalism considered as a doctrine in the philosophy of mind-- from a view that does not in any way involve the Denial: psychological methodological behaviourism. Second, the rise of a way of understanding naturalism --materialist or physicalist naturalism-- that wrongly takes naturalism to entail the Denial. (shrink)

Teresa believes in God. Maggie’s wife believes that the Earth is flat, and also that Maggie should be home from work by now. Anouk—a cat—believes it is dinner time. This dissertation is about what believing is: it concerns what, exactly, ordinary people are attributing to Teresa, Maggie’s wife, and Anouk when affirming that they are believers. Part I distinguishes the attitudes of belief that people attribute to each other (and other animals) in ordinary life from the cognitive states of belief (...) theoretically posited by (some) cognitive scientists. Part II defends the view that to have an attitude of belief is to live—to be disposed to act, react, think, and feel—in a pattern that an actual belief attributor identifies with taking the world to be some way. Drawing on scientific, scholarly, and literary sources of evidence, How Beliefs are like Colors provides a framework for research on belief across the humanities and sciences of the mind. (shrink)

We examine the question of whether scientific theories can ever be complete. For two closely related reasons, we will argue that they cannot. The first reason is the inability to determine what are “valid empirical observations”, a result that is based on a self-reference Gödel/Tarski-like proof. The second reason is the existence of “meta-empirical” evidence of the inherent incompleteness of observations. These reasons, along with theoretical incompleteness, are intimately connected to the notion of belief and to theses within the philosophy (...) of science: the Quine-Duhem (and underdetermination) thesis and the observational/theoretical distinction failure. Some puzzling aspects of the philosophical theses will become clearer in light of these connections. Other results that follow are: no absolute measure of the informational content of empirical data, no absolute measure of the entropy of physical systems, and no complete computer simulation of the natural world are possible. The connections with the mathematical theorems of Gödel and Tarski reveal the existence of other connections between scientific and mathematical incompleteness: computational irreducibility, complexity, infinity, arbitrariness and self-reference. Finally, suggestions will be offered of where a more rigorous (or formal) “proof” of scientific incompleteness can be found. (shrink)

Frank Jackson’s knowledge argument is a very influential piece of reasoning that seeks to show that colour experiences constitute an insoluble problem for science. This argument is based on a thought experiment concerning Mary. She is a vision scientist who has complete scientific knowledge of colours and colour vision but has never had colour experiences. According to Jackson, upon seeing coloured objects, Mary acquires new knowledge that escapes her complete scientific knowledge. He concludes that there are facts concerning colour experiences (...) that scientific knowledge can neither describe nor explain. Specifically, these facts involve the occurrence of certain non-physical properties of experiences that he calls qualia. The present research considers whether a plausible formulation of the hypothesis that science can accommodate colour experiences is threatened by a version of the knowledge argument. The specific formulation of this problem has two motivations. Firstly, before investigating whether the knowledge argument raises a problem for the claim that science can account for colour experiences, we need a plausible formulation of this claim. I argue that the idea that science can accommodate colour experiences can be formulated as the modest reductionism hypothesis. Roughly speaking, this is the hypothesis that a science that can be explanatory interfaced with current physics of ordinary matter can account for conscious experiences. Secondly, an unintelligible premise figures in Jackson’s version the knowledge argument. Namely, it is assumed that Mary possesses a complete scientific knowledge. Nevertheless, the type of strategy involved in Jackson’s argument can be used to target modest reductionism. By considering contemporary psychophysics and neuroscience, I characterise Mary’s scientific knowledge. First, this characterisation is intelligible. In fact, it is elaborated on the basis of descriptions and explanations of colour experiences involved in current physics and neuroscience. Second, a supporter of modest reductionism can assume that the scientific knowledge ascribed to Mary might account for colour experiences. The main conclusion of the present research is that our version of the knowledge argument fails to threaten the modest reductionism hypothesis. In fact, I endorse what can be called the “two ways of thinking” reply to the knowledge argument. According to this response, the knowledge argument shows that there are different ways of thinking about colour experiences. One way of thinking is provided by scientific knowledge. The other way of thinking is provided by our ordinary conception of colour experiences. However, the existence of these two ways of thinking does not imply the existence of facts and properties that escape scientific knowledge. It might be the case that the ordinary way of thinking about colour experience concerns facts and properties described and explained by science. The principal conclusion of the research results from two investigations. The first line of research aims to reveal and evaluate the implicit assumptions that figure in the knowledge argument. The main body of the research is dedicated to this task. The principal result of this investigation is that the knowledge argument must rely on an account of introspective knowledge of colour experiences. I argue that an inferential model of introspection provides such account. On this model, Mary’s capacity to hold beliefs about her colour experiences when she sees coloured objects requires her mastery of colour concepts. The second main investigation seeks to justify the two ways of thinking strategy. As many opponents and supporters have recently started to realise, this strategy might be charged with being ad hoc. I offer a distinctive justification of this reply to the knowledge argument. Assuming the account of introspection mentioned above, the existence of visual recognitional colour concepts might justify this strategy. A person possesses these concepts when she is able to determine the colours of objects simply by having visual experiences. (shrink)

Color relationalism is the view that colors are constituted in terms of relations between subjects and objects. The most historically important form of color relationalism is the classic dispositionalist view according to which, for example red is the disposition to look red to standard observers in standard conditions (mutatis mutandis for other colors).1 However, it has become increasingly apparent in recent years that a commitment to the relationality of colors bears interest that goes beyond dispositionalism (Cohen, 2004; Matthen, 1999, 2001, (...) 2005; Thompson, 1995). Accordingly, it is an important project for those interested in the metaphysics of color to sort through and assess different forms of color relationalism. There is, however, a powerful and general cluster of objections that has been thought by many to amount to a decisive refutation of any and all forms of color relationalism. Although this idea has been developed in a number of ways, the basic thought is that relationalism — qua theory of color — is at odds with the manifest evidence of color phenomenology, and that this clash between theory and data should be resolved by giving up the theory.

La ricerca empirica nelle scienze cognitive può essere di supporto all’indagine filosofica sullo statuto ontologico e epistemologico dei concetti mentali, ed in particolare del concetto di credenza. Da oltre trent’anni gli psicologi utilizzano il test della falsa credenza per valutare la capacità dei bambini di attribuire stati mentali a se stessi e a agli altri. Tuttavia non è stato ancora pienamente compreso né quali requisiti cognitivi siano necessari per passare il test né quale sia il loro sviluppo. In questo articolo (...) analizzo l’impatto della funzione esecutiva e delle abilità linguistiche per la capacità di passare il test della falsa credenza. Suggerisco che tale abilità dipende dall’acquisizione di un nuovo formato rappresentazionale per codificare la falsità degli stati mentali altrui. I dati in nostro possesso non permettono tuttavia di precisare la natura di tale formato. (shrink)

Most discussion of Sellars’ deployment of the distinct images of “man-in-the-world” in Philosophy and the Scientific Image of Man focus entirely on the manifest and the scientific images. But the original image is important as well. In this essay I explore the importance of the original image to the Sellarsian project of naturalizing epistemology, connecting Sellars’ insights regarding this image to recent work in cognitive development.
