Several forms of naturalism are currently extant. Proponents of the various approaches disagree on matters of strategy and detail but one theme is common: we have not received any revelations about the nature of the world -- including our own nature. Whatever knowledge we have has been acquired through a fallible process of conjecture and revision. This common theme will bring to mind the writings of Karl Popper and, in many respects, Popper is the father of contemporary naturalism. Along with (...) Popper, the form of naturalism that I would defend is realistic in the following sense: it considers the acquisition of knowledge of the nature of the world to be a pursuable long-term goal of our epistemic activities. (See Brown [1987, 1988, 1990].) Popper's central interest in truth has led him to object to the pervasive concern with concepts among contemporary philosophers. Truth, Popper insists, is the fundamental epistemic concern; propositions are the bearers of truth; and the evaluation of propositions should be at the center of our epistemic focus (e.g., 1965, pp. 18-21; 1972, pp. 123-24). Concern with concepts, Popper maintains, is a distraction. Yet, this leaves us in an odd position. When we study a particular subject matter, one of our main problems is to determine what kinds of entities and processes occur in that domain. But the kinds of entities and processes we attribute to a domain will be captured in the concepts we use for describing that domain and, from a naturalistic point of view, concepts are no more available through revelation than are propositions. As our knowledge develops, we must not only propose and evaluate propositions, we must also propose and evaluate concepts. (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.

A concrete proposal is presented as to how semantics should be naturalized. Rather than attempting to naturalize propositions, they are treated as abstract entities that index concrete cognitive states. In turn the relevant concrete cognitive states are identified via perceptual classifications of worldly states, with the aid of an interactive theory of perception. The approach enables a broadly realist theory of propositions, truth and cognitive states to be preserved, with propositions functioning much as abstract mathematical constructs do in the nonsemantic (...) sciences, but with a much more specific propositional indexing scheme than previous naturalistic proposals were able to achieve.

Naturalists seek continuity between epistemology and science. Critics argue this illegitimately expands science into epistemology and commits the fallacy of scientism. Must naturalists commit this fallacy? I defend a conception of naturalized epistemology which upholds the non-identity of epistemic ends, norms, and concepts with scientific evidential ends, norms, and concepts. I argue it enables naturalists to avoid three leading scientistic fallacies: dogmatism, one dimensionalism, and granting science an epistemic monopoly.

I propose and defend the Allocentric-Egocentric Interface Theory of Con- sciousness. Mental processes form a hierarchy of mental representations with maxi- mally egocentric (self-centered) representations at the bottom and maximally allocentric (other-centered) representations at the top. Phenomenally conscious states are states that are relatively intermediate in this hierarchy. More speci.

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)

Many philosophers hold that for various reasons there must be psychological laws governing beliefs and desires. One of the few serious examples that they offer is the _belief-desire law_, which states, roughly, that _ceteris paribus_ people do what they believe will satisfy their desires. This paper argues that, in fact, there is no such law. In particular, decision theory does not support the contention that there is such a law.

The question, What is Folk Epistemology?, is a question receiving increasing attention, but one that still awaits a sustained answer. In the present work by Mikkel Gerken,1 1 we have a somewhat different question discussed: What should FE be?

I explore the Because Constraint—the idea that moral facts depend on natural facts and that moral judgements ought to respect the dependence of moral facts on natural facts. I consider several issues concerning its clarification and importance.

In this paper, I compare theory-laden perceptions with imputed data sets. The similarities between the two allow me to show how the phenomenon of theory-ladenness can manifest itself in statistical analyses. More importantly, elucidating the differences between them will allow me to broaden the focus of the existing literature on theory-ladenness and to introduce some much-needed nuances.

This paper proposes a set of criteria for an appropriate experiment on the issue of the theory ladenness of perception. These criteria are used to select a number of experiments that use: belief-based ambiguous figures, fragmented figures, or memory color. Crucially, the data in experiments of this type are based on the participant’s qualitative visual experience. Across many different types of experimental designs, different types of stimuli, and different types of belief manipulation, these experiments show the impact of belief/theory on (...) visual perception. Using an ecological validity argument, I conclude that attention-based interpretations of these findings are not successful because the relevant epistemological issues only require that we examine final perception, in the sense of visual awareness of the everyday world. Finally, I argue that the epistemological consequences of theory-ladenness can be reduced by using a top-down/bottom-up theoretical framework and by adopting appropriate methodological procedures to data derived from individual observations.

According to a simple form of consequentialism, we should base decision on our judgments about their consequences for achieving out goals. Our goals give us reason to endorse consequentialism as a standard of decision making. Alternative standards invariably lead to consequences that are less good in this sense. Yet some people knowingly follow decision rules that violate consequentialism. For example, they prefer harmful omissions to less harmful acts, they favor the status quo over alternatives they would otherwise judge to be (...) better, they provide third-party compensation on the basis of the cause of an injury rather than the benefit from the compensation, they ignore deterrent effects in decisions about punishment, and they resist coercive reforms they judge to be beneficial. I suggest that nonconsequentialist principles arise from overgeneralizing rules that are consistent with consequentialism in a limited set of cases. Commitment to such rules is detached from their original purposes. The existence of such nonconsequentialist decision biases has implications for philosophical and experimental methodology, the relation between psychology and public policy, and education. (shrink)

This article presents a formal theory of robot perception as a form of abduction. The theory pins down the process whereby low‐level sensor data is transformed into a symbolic representation of the external world, drawing together aspects such as incompleteness, top‐down information flow, active perception, attention, and sensor fusion in a unifying framework. In addition, a number of themes are identified that are common to both the engineer concerned with developing a rigorous theory of perception, such as the one on (...) offer here, and the philosopher of mind who is exercised by questions relating to mental representation and intentionality.

Recent proponents of the ‘theory theory’ of mind often trace its roots back to Wilfrid Sellars’ famous ‘myth of Jones’ in his 1956 article, ‘Empiricism and the Philosophy of Mind’. Sellars developed an account of the intersubjective basis of our knowledge of the inner mental states of both self and others, an account which included the claim that such knowledge is in some sense theoretical knowledge. This paper examines the nature of this claim in Sellars’ original account and its relationship (...) to more recent debates concerning ‘theory of mind’, in particular the theory theory. A close look reveals that Sellars’ original view embodied several distinctions that would enable more recent theory theorists to accommodate certain phenomenological objections that have been raised against that outlook. At the heart of the philosophical issue is an overlooked complexity involved in Sellars’ account of the ‘theory/observation’ distinction, involving a conception of the distinction that is both independently plausible and a key to the issue in dispute.

It has been argued that naturalizing the mind will result in the elimination of the ontology of folk psychology (e.g. beliefs and desires). This paper draws from a wide range of empirical literature, including from developmental and cross-cultural psychology, in building an argument for a position dubbed restrictive materialism . The position holds that while the ontology of folk psychology is overextended, there is a restricted domain in which the application of the folk ontology remains secure. From the evidence of (...) developmental uniformity and cross-cultural ubiquity of beliefs and desires, it is argued that the ontology (but not the principles) of folk psychology may be incorrigible. Thus, even if radically false as a description of first-order brain processes, beliefs and desires might be an unavoidable second-order brain process. Given that the domain of psychology is how humans think, if the above argument is correct, then beliefs and desires will continue to earn their rightful place in the ontology of any future psychology, in just the same way as any other scientific entity.

This book contains a representationalist theory of self-consciousness and of the phenomenal first-person perspective. It draws on empirical data from the cognitive and neurosciences.

Propositions, the abstract, truth-bearing contents of sentences and beliefs, continue to be the focus of healthy debates in philosophy of language and metaphysics. This article is a critical survey of work on propositions since the mid-90s, with an emphasis on newer work from the past decade. Topics to be covered include a substitution puzzle about propositional designators, two recent arguments against propositions, and two new theories about the nature of propositions.

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)

Lerdahl and Jackendoff's Generative Theory of Tonal Music (GTTM) is an important contribution to cognitive science. Jackendoff claims it is a computationalist theory and that the mental representations it postulates are unconscious. Thus GTTM looks to be a kind of cognitive science remote from the folk-psychological. I argue that this picture of GTTM is mistaken: GTTM is at least as much music analysis as cognitive science. Jackendoff's metatheory fails to explain how a listener can tell that a structural description corresponds (...) to the way she hears, how analytically minded listeners can communicate about their hearing, and how a reader of their book can comprehend it. I suggest an alternative construal, on which GTTM's analytical vocabulary functions as a public language and its mental representations are perceptual beliefs. Interesting philosophical problems ensue about knowledge of musical structure and knowledge about what structures one hears. There is a paradox: one wants an analysis to be true to a hearing, yet to be illuminating. Though analysis and hearing coincide in content at an abstract level, they do not coincide in conceptual content. What sort of knowledge then underlies the inference from perceptual to music-analytical representation? I argue that such knowledge is a priori. (shrink)

Functionalism in the philosophy of mind is here criticized from the perspective of a more naturalistic and less compromising form of materialism. Parallels are explored between the problem of cognitive activity and the somewhat more settled problem of vital activity. The lessons drawn suggest that functionalism in the philosophy of mind may be both counterproductive as a research strategy, and false as a substantive position.

John Perry’s new book makes an important philosophical contribution at two quite distinct levels. The first and most obvious is its systematic critical discussion of three of the most notorious recent arguments in favor of some form of Property Dualism: Chalmers’ Zombie Argument, Jackson’s Knowledge Argument, and Kripke’s Modal Argument. Perry—no stranger himself to matters modal, indexical, and demonstrative—brings an especial authority to this task. Unlike many of us, he eats, drinks, and breathes the same modal vocabulary deployed by all (...) three of these authors, and, unlike some of us, he accepts most of what passes for conventional wisdom in current modal theory. Moreover, while “antecedently inclined” toward some form of physicalism in the philosophy of mind, he has no particular ideological axe to grind here. Perry never turns to extol the positive virtues of this, that, or the other materialist theory of mind above its various dualist adversaries. He just wishes to determine whether any of the three celebrated arguments cited above provides the antecedent materialist with a motive for reconsidering that general position. Other readers will be eager, as was I, to see how a judge with Perry’s solid but prototypically “analytic” credentials comes down on this issue. (shrink)

This article argues that the much-maligned ‘notational variants’ of a given formal linguistic theory play a role similar to alternative numerical measurement scales. Thus, they can be used to identify the invariant components of the grammar; i.e., those features that do not depend on the choice of empirically equivalent representation. Treating these elements as the ‘meaningful’ structure of language has numerous consequences for the philosophy of science and linguistics. I offer several such examples of how linguistic theorizing can profit from (...) adopting a measurement-theoretic viewpoint. The first concerns a measurement-theoretic response to a famous criticism of Quine's. Others follow from issues of simplicity in the current biolinguistics program. An unexpected similarity with behaviorist practices is also uncovered. I then argue that managable and useful steps can be taken in this area. (shrink)
