It is often claimed (1) that levels of nature are related by supervenience, and (2) that processes occurring at particular levels of nature should be studied using dynamical systems theory. However, there has been little consideration of how these claims are related. To address the issue, I show how supervenience relations give rise to ‘supervenience functions’, and use these functions to show how dynamical systems at different levels are related to one another. I then use this analysis to describe a (...) graded approach to non-reductive physicalism, and to critically assess Davidson’s arguments for psychological anomaly. I also show how this approach can inform empirical research in cognitive science. (shrink)

The essay discusses Donald Davidson’s concept of anomalous monism in the framework of Husserlian phenomenology. It develops in four stages. Section 1 is devoted to a critical presentation of the argument for anomalous monism. Section 2 succinctly examines those Husserlian notions that best provide the ground for a discussion parallel to Davidson’s. In Sect. 3, the aporetic status of “mental causation” is analyzed by providing a genetic-phenomenological account of efficient causation. Section 4 draws some general conclusions concerning the kind of (...) efficaciousness that must be attributed to consciousness and discusses the sense in which anomalous monism can be defended in a phenomenological framework, but not in a naturalistic one.

Supervenience was first used by Donald Davidson to describe the dependent and independent relationships between the mental and the physical. Jaegwon Kim presented a more precise definition, distinguishing between three types of supervenience: weak, strong and global. Kim further proved that strong and global supervenience are equivalent. However, three years later, Kim argued that strong supervenience is stronger than global supervenience, while weak supervenience and global supervenience are independent of each other. This paper demonstrates that Kim’s conclusion that weak supervenience (...) and global supervenience are independent of each other is wrong. The strength of strong, weak and global supervenience decreases in turn with the latter entailed by the former. This paper also corrects some defects in Kim’s argument and his formulation of strong and weak supervenience, and then further explores the relationship between the three types of supervenience and their philosophical significance. It also classifies other terms of supervenience such as layered supervenience, macro-micro supervenience, and mereological superveniece as relationships of the strong, weak and global. (shrink)

How do we know what our intentions are? It is argued that work on self-knowledge has tended to neglect the attitude of intention, and that an epistemological account is needed that is attuned to the specific features of that state. Richard Moran’s Authorship view, on which we can acquire self-knowledge by making up our minds, offers a promising insight for such an account: we do not normally discover what we intend through introspection. However, his formulation of the Authorship view, developed (...) primarily with the attitude of belief in mind, is found wanting when applied to intention. An alternative account is proposed for knowledge of one’s own intentions that gives a central role to the mental act of deciding what to do. It is argued that we can come to know what we intend by making a decision about what to do and self-ascribing the content of that decision as our intended action. (shrink)

There are various approaches to truth and knowledge (in fact, cataloguing them has become something of a philosophical industry of its own); and in many cases, their explanations are taken to underlie the explanation of other crucial concepts, like language, reason etc. Especially in recent years, some of the approaches have come to be based on reducing semantics to pragmatics. An outstanding example of such a pragmatist approach is that of Bob Brandom, who bases the explication of both truth and (...) knowledge on his consideration of normative pragmatics. A less explicitly pragmatist approach to truth and knowledge was offered by Donald Davidson (who is surely not a pragmatist in the narrow sense of the word, but may be thought about as one in the wider sense proposed by Brandom, 2002, in which pragmatism means starting from the practical rather than the theoretical). In this paper I would like to point out that the discrepancy between these two approaches may be smaller than it would prima facie seem. To show this, I first turn my attention briefly to the general problem of theoretically accounting for human minds. (shrink)

When Charles Darwin died in April, 1882, he left behind a world changed forever. Because of his writings, most notably, of course, The Origin of Species, by 1882, evolution was an almost universally acknowledged fact. What remained in dispute, however, was how evolution occurred. So because of Darwin’s work, everyone accepted that new species emerge over time, yet few agreed with him that it was natural selection that powered the change, as Darwin hypothesized. Chalmers’ book, The Conscious Mind , reminds (...) me of The Origin of Species . I have talked t o many people about The Conscious Mind and watched many philosophy students read it, and after they are done, they all take consciousness more seriously than they did before and they are all struck by its deep mystery, yet few accept Chalmers’ specific theory of consciousness and his explanation of its odd nature.

Psychology has been considered to have an autonomy from the other sciences (especially physical science) in at least two ways: in its subject-matter and in its methods. To say that the subject-matter of psychology is autonomous is to say that psychology deals with entities—properties, relations, states—which are not dealt with or not wholly explicable in terms of physical (or any other) science. Contrasted with this is the idea that psychology employs a characteristic method of explanation, which is not shared by (...) the other sciences. I shall label the two senses of autonomy ‘metaphysical autonomy’ and ‘explanatory autonomy’ The question of whether psychology as a science is autonomous in either sense is one of the philosophical questions surrounding the (somewhat vague) doctrine of ‘naturalism’: questions concerning the extent to which the human mind can be brought under the aegis of natural science. In their contemporary form, these questions had their origin in the ‘new science’ of the 17th century. Early materialists like Hobbes (1651) and La Mettrie (1748) rejected both explanatory and metaphysical autonomy: mind is matter in motion, and the mind can be studied by the mathematical methods of the new science just as any matter can. But while materialism (and therefore the denial of metaphysical autonomy) had to wait until the 19th century before starting to become widely accepted, the denial of explanatory autonomy remained a strong force in empiricist philosophy. Hume described his Treatise of Human Nature (1739-40) as an ‘attempt to introduce the experimental method of reasoning into moral subjects’—where ‘moral’ signifies ‘human’. And subsequent criticism of Hume’s views, notably by Kant and Reid, ensured that the question of naturalism—whether there can be a ‘science of man’—was one of the central questions of 19th century philosophy, and a question which hovered over the emergence of psychology as an independent discipline (see Reed 1994). In the 20th century, much of the philosophical discussion of the autonomy of psychology has been inspired by the Logical Positivists’ discussions of the UNITY OF.... (shrink)

A rigorous approach to the study of the mind–body problem is suggested. Since humans are able to talk about consciousness (produce phenomenal judgments), it is argued that the study of neural mechanisms of phenomenal judgments can solve the hard problem of consciousness. Particular methods are suggested for: (1) verification and falsification of materialism; (2) verification and falsification of interactionism; (3) falsification of epiphenomenalism and parallelism (verification is problematic); (4) verification of particular materialistic theories of consciousness; (5) a non-Turing test for (...) machine consciousness. A complex research program is constructed that includes studies of intelligent machines, numerical models of human and artificial creatures, language, neural correlates of con- sciousness, and quantum mechanisms in brain.

The paper argues in favour of a causal-functional theory of all properties including the physical ones and a conception of properties as tropes or modes in the sense of particular ways that objects are. It shows how these premises open up a version of functionalism according to which the properties on which the special sciences focus are identical with configurations of physical properties and thereby causally efficacious without there being any threat of eliminativism.

I argue that the most popular versions of naturalism imply nominalism in philosophy of mathematics. In particular, there is a conflict in Quine's philosophy between naturalism and realism in mathematics. The argument starts from a consequence of naturalism on the nature of human cognitive subjects, physicalism about cognitive subjects, and concludes that this implies a version of nominalism, which I will carefully characterize. The indispensability of classical mathematics for the sciences and semantic/confirmation holism does not affect the argument. The disquotational (...) theory of reference and truth is discussed but rejected. This argument differs from the Benacerrafian arguments against realism, because it does not rely on any specific assumption about the nature of knowledge or reference. It differs from the popular objections to the indispensability argument for realism as well, because it can admit both indispensability and holism. This argument motivates a new, radically naturalistic and nominalistic approach to philosophy of mathematics. (shrink)

In this paper I argue that Davidson's solution to the paradoxes of irrationality is incompatible with his holistic assumption on the mental.

In this paper we briefly examine and evaluate Quine’s physicalism. On the supposition, in accordance with Quine’s views, that there can be no change of any sort without a physical change, we argue that this point leaves plenty of room to understand and accept a limited autonomy of the special sciences and of other domains of disciplinary and common-sense inquiry and discourse. The argument depends on distinguishing specific, detailed programs of reduction from the general Quinean strategy of reduction by explication. (...) We argue that the details of the relations of particular sciences, disciplines and domains of discourse depend on empirical evidence and empirical-theoretical developments and that the generalized approach of reduction by explication is also subject to related empirical-theoretical constraints. So understood, physicalism lacks much of the controversial force and many of the implications sometimes associated with it. (shrink)

The realization relation that allegedly holds between mental and physical properties plays a crucial role for so-called non-reductive physicalism because it is supposed to secure both the ontological autonomy of mental properties and, despite their irreducibility, their ability to make a causal difference to the course of the causally closed physical world. For a long time however, the nature of realization has largely been ignored in the philosophy of mind until a couple of years ago authors like Carl Gillett, Derk (...) Pereboom, or Sydney Shoemaker proposed accounts according to which realization is understood against the background of the so-called 'causal theory of properties'. At least partially, the hope was to solve the problem of mental causation, in particular the kind of causal exclusion reasoning made famous by Jaegwon Kim, in a way acceptable to nonreductive physicalists. The paper asks whether a proper explication of the realization relation can indeed help explain how physically realized mental properties can be causally efficacious in the causally closed physical world and argues for a negative answer: it is important for the non-reductive physicalist to understand what exactly the realization relation amounts to, but it does not solve the problem of mental causation.

Frank Jackson’s knowledge argument (KA) aims to prove, by means of a thought experiment concerning the hypothetical scientist Mary, that conscious experiences have non-physical properties, called qualia. Mary has complete scientific knowledge of colours and colour vision without having had any colour experience. The central intuition in the KA is that, by seeing colours, Mary will learn what it is like to have colour experiences. Therefore, her scientific knowledge is incomplete, and conscious experiences have qualia. In this paper I consider (...) an objection to the KA raised by Daniel Dennett. He maintains that the KA is vitiated by Jackson’s account of Mary’s scientific knowledge. While endorsing this criticism, I will defend the plausibility and relevance of the type of strategy involved in the KA by offering an account of Mary’s scientific knowledge. This account involves formulating a reasonable and not immediately false version of the physicalist thesis with regard to colour experiences. Whether this version of the KA is successful against this type of physicalism is not investigated here. (shrink)

Externalism about mental content is now widely accepted. It is therefore surprising that there is no established definition of externalism. I believe that this is a symptom of an unrecognized fact: that the labels 'mental content externalism' -- and its complement 'mental content internalism' -- are profoundly ambiguous. Under each of these labels falls a hodgepodge of sometimes conflicting claims about the organism's contribution to thought contents, the nature of the self, relations between the individual and her community, and the (...) epistemic availability of thoughts. This situation stems from the fact that contributors to debates about externalism differ in how they understand 'internal property'; these differences reveal (or, perhaps, generate) disparate conceptions of what is at issue in these debates. I argue that this situation is irremediable. There is no way to understand 'internal property' that will conform with prevailing beliefs about the nature of internalism and externalism, and with the usual taxonomy of leading positions. This ambiguity carries a heavy price: participants in these debates often argue at cross-purposes, disagreeing even on the nature of the evidence that could settle the question of externalism. Progress on the broad range of issues associated with these debates requires that we abandon the categories 'internalism' and 'externalism'. I close by suggesting a promising avenue for future research related to these issues. (shrink)

Jaegwon Kim’s supervenience/exclusion argument attempts to show that non-reductive physicalism is incompatible with mental causation. This influential argument can be seen as relying on the following principle, which I call “the piggyback principle”: If, with respect to an effect, E, an instance of a supervenient property, A, has no causal powers over and above, or in addition to, those had by its supervenience base, B, then the instance of A does not cause E (unless A is identical with B). In (...) their “Epiphenomenalism: The Dos and the Don’ts,” Larry Shapiro and Elliott Sober employ a novel empirical approach to challenge the piggyback principle. Their empirical approach pulls from the experiments of August Weismann regarding the inheritance of acquired characteristics. Through an examination of Weismann’s experiments, Shapiro and Sober extract lessons in reasoning about the epiphenomenalism of a property. And according to these empirically drawn lessons, the piggyback principle is a don’t. My primary aim in this paper is to defend the piggyback principle against Shapiro and Sober’s empirical approach.

An interpretation of Hegel's Philosophy of Subjective Spirit showing its continued relevance to contemporary issues in the philosophy of mind.

In everyday discourse and in the context of social scientific research we often attribute intentional states to groups. Contemporary approaches to group intentionality have either dismissed these attributions as metaphorical or provided an analysis of our attributions in terms of the intentional states of individuals in the group.Insection1, the author argues that these approaches are problematic. In sections 2 and 3, the author defends the view that certain groups are literally intentional agents. In section 4, the author argues that there (...) are significant reasons for social scientists and philosophers of social science to acknowledge the adequacy of macro-level explanations that involve the attribution of intentional states to groups. In section 5, the author considers and responds to some criticisms of the thesis she defends. (shrink)

In Part I, the author argued for nonreductive individualism (NRI), an account of the individual-collective relation that is ontologically individualist yet rejects methodological individualism. However, because NRI is ontologically individualist, social entities and properties would seem to be only analytic constructs, and if so, they would seem to be epiphenomenal, since only real things can have causal power. In general, a nonreductionist account is a relatively weak defense of sociological explanation if it cannot provide an account of how social properties (...) can participate in causal relations. In this article, the author extends NRI to address this weakness and provides an account of social causation that he refers to as supervenient causation. Key Words: individualism • collectivism • social realism • social causation. (shrink)

The central part of Everett's formulation of quantum mechanics is a quantum mechanical model of memory and of observation as the recording of information in a memory. To use this model as an answer to the measurement problem, Everett has to assume that a conscious observer can be in a superposition of such memory states and be unaware of it. This assumption has puzzled generations of readers. ;The fundamental aim of this dissertation is to find a set of simpler assumptions (...) which are sufficient to show that Everett's model is empirically adequate. I argue that Everett's model needs three assumptions to account for the process of observation: an assumption of decoherence of observers as quantum mechanical systems; an assumption of supervenience of mental states over quantum mechanical properties; and an assumption about the interpretation of quantum mechanical states in general: quantum mechanical states describe ensembles of states of affairs coexisting in the same system. I argue that the only plausible understanding of such ensembles is as ensembles of possibilities, and that all standard no-collapse interpretations agree in this reading of quantum mechanical states. Their differences can be understood as different theories about what marks the real state within this ensemble, and Everett's theory as the claim that no additional 'mark of reality' is necessary. ;Using the three assumptions, I argue that introspection cannot determine the objective quantum mechanical state of an observer. Rather, the introspective qualities of a quantum mechanical state can be represented by a statistical ensemble of subjective states. An analysis of these subjective states and their dynamics leads to the conclusion that they suffice to give empirically correct predictions. The argument for the empirical adequacy of the subjective state entails that knowledge of the objective quantum mechanical state is impossible in principle. Empirical reality for a conscious observer is not described by the objective state, but by a Everettian relative state conditional on the subjective state, and no theoretical 'mark of reality' is necessary for this concept of reality. I compare the resulting concept of reality to Kant's distinction between empirical and transcendental reality. (shrink)

The Gestalt principle of isomorphism reveals the primacy of subjective experience as a valid source of evidence for the information encoded neurophysiologically. This theory invalidates the abstractionist view that the neurophysiological representation can be of lower dimensionality than the percept to which it gives rise.

In their recent book Philosophical Foundations of Neuroscience, Max Bennett and Peter Hacker attack neural materialism (NM), the view, roughly, that mental states (events, processes, etc.) are identical with neural states or material properties of neural states (events, processes, etc.). Specifically, in the penultimate chapter entitled “Reductionism,” they argue that NM is unintelligible, that “there is no sense to literally identifying neural states and configurations with psychological attributes.” This is a provocative claim indeed. If Bennett and Hacker are right, then (...) a sizeable number of philosophers, cognitive scientists, neuroscientists, etc., subscribe to a view that is not merely false, but strictly meaningless. In this article I show that Bennett and Hacker's arguments against NM, whether construed as arguments for the meaninglessness of or the falsity of the thesis, cannot withstand scrutiny: when laid bare they are found to rest upon highly dubious assumptions that either seriously mischaracterize or underestimate the resources of the thesis.

Some claim that Non- reductive Physicalism is an unstable position, on grounds that NRP either collapses into reductive physicalism, or expands into emergentism of a robust or ‘strong’ variety. I argue that this claim is unfounded, by attention to the notion of a degree of freedom—roughly, an independent parameter needed to characterize an entity as being in a state functionally relevant to its law-governed properties and behavior. I start by distinguishing three relations that may hold between the degrees of freedom (...) needed to characterize certain special science entities, and those needed to characterize their composing physical entities; these correspond to what I call ‘reductions’, ‘restrictions’, and ‘eliminations’ in degrees of freedom. I then argue that eliminations in degrees of freedom, in particular—when strictly fewer degrees of freedom are required to characterize certain special science entities than are required to characterize their composing physical entities—provide a basis for making sense of how certain special science entities can be both physically acceptable and ontologically irreducible to physical entities.

My primary aim in this chapter is to explain in what the traditional mind–body problem consists, what its possible solutions are, and what obstacles lie in the way of a resolution. The discussion will develop in two phases. The first phase, sections 1.2–1.4, will be concerned to get clearer about the import of our initial question as a precondition of developing an account of possible responses to it. The second phase, sections 1.5–1.6, explains how a problem arises in our attempts (...) to answer the question we have characterized, and surveys the various solutions that can be and have been offered. More specifically, sections 1.2–1.4 are concerned with how to understand the basic elements of our initial question – how we should identify the mental, on the one hand, and the physical, on the other – and with what sorts of relations between them we are concerned. Section 1.2 identifies and explains the two traditional marks of the mental, consciousness and intentionality, and discusses how they are related. Section 1.3 gives an account of how we should understand ‘physical’ in our initial question so as not to foreclose any of the traditional positions on the mind–body problem. Section 1.4 then addresses the third element in our initial question, mapping out the basic sorts of relations that may hold between mental and physical phenomena, and identifying some for special attention. Sections 1.5–1.6 are concerned with explaining the source of the difficulty in answering our initial question, and the kinds of solutions that have been offered to it. Section 1.5 explains why our initial question gives rise to a problem, and gives a precise form to the mind–body problem, which is presented as a set of four propositions, each of which, when presented independently, seems compelling, but which are jointly inconsistent. Section 1.6 classifies responses to the mind–body problem on the basis of which of the propositions in our inconsistent set they reject, and provides a brief overview of the main varieties in each category, together with some of the difficulties that arise for each. Section 1.7 is a brief conclusion about the source of our difficulties in understanding the place of mind in the natural world. (shrink)

One of the recurrent problems in the foundations of physics is to explain why we rarely observe certain phenomena that are allowed by our theories and laws. In thermodynamics, for example, the spontaneous approach towards equilibrium is ubiquitous yet the time-reversal-invariant laws that presumably govern thermal behaviour in the microscopic level equally allow spontaneous departure from equilibrium to occur. Why are the former processes frequently observed while the latter are almost never reported? Another example comes from quantum mechanics where the (...) formalism, if considered complete and universally applicable, predicts the existence of macroscopic superpositions—monstrous Schr¨odinger cats—and these are never observed: while electrons and atoms enjoy the cloudiness of waves, macroscopic objects are always localized to definite positions.

is true, there is a truth-maker (e.g., a fact) with which it is identical and the truth of the former consists in its identity with the latter. The theory is best understood as a reaction to the correspondence theory, according to which the relation of truth-bearer to truth-maker is correspondence. A correspondence theory is vulnerable to the nagging suspicion that if the best we can do is make statements that merely correspond to the truth, then we inevitably fail to capture (...) the reality they are about and thus fall short of the truth we aim at. An identity theory is designed to overcome this suspicion. (shrink)

Causal necessity typically receives only oblique attention. Causal relations, laws of nature, counterfactual conditionals, or dispositions are usually the immediate subject(s) of interest. All of these, however, have a common feature. In some way, they involve the causal modality, some form of natural or physical necessity. In this paper, causal necessity is discussed with the purpose of determining whether a completely general empiricist theory can account for the causal in terms of the noncausal. Based on an examination of causal relations, (...) laws of nature, counterfactual conditionals, and dispositions, it is argued that no reductive program devoid of essentialist commitments can account for all the phenomena that involve causal necessity. Hence, neo-Humean empiricism fails to provide a framework adequate for understanding causal necessity. (shrink)

The occurrence or apparent occurrence of incontinent actions challenges several influential views in ethics and the philosophy of mind, e.g., Hare's prescriptivism and the Socratic idea that we always act in the light of the imagined greatest good. It also raises, as I shall explain, an interesting and instructive problem for proponents of causal theories of action. But whereas Socrates and Hare attempt to avoid the difficulties with which akrasia confronts them by denying - wrongly, I shall argue - that (...) there are akratic actions ([15], 352a-358d; [13], Ch. 5), the causal theorist need not take this unhappy tack. In this paper I shall argue that the truth of a causal theory of action (CTA) is compatible with the occurrence of akratic actions and, in particular, with akratic actions against what I shall call a "here-and-now" intention - i.e., an intention of the agent to do an A here and now. I shall suggest that akratic actions of this type plainly do occur, and I shall attempt to explain how they might be accommodated by a causal theory of action. (shrink)

J. L. Mackie argued that if there were objective moral properties or facts, then the supervenience relation linking the nonmoral to the moral would be metaphysically queer. Moral realists reply that objective supervenience relations are ubiquitous according to contemporary versions of metaphysical naturalism and, hence, that there is nothing especially queer about moral supervenience. In this paper we revive Mackie's challenge to moral realism. We argue: (i) that objective supervenience relations of any kind, moral or otherwise, should be explainable rather (...) than sui generis; (ii) that this explanatory burden can be successfully met vis-à-vis the supervenience of the mental upon the physical, and in other related cases; and (iii) that the burden cannot be met for (putative) objective moral supervenience relations.

In this paper I offer an analysis of causation based upon a theory of mechanisms-complex systems whose internal parts interact to produce a system's external behavior. I argue that all but the fundamental laws of physics can be explained by reference to mechanisms. Mechanisms provide an epistemologically unproblematic way to explain the necessity which is often taken to distinguish laws from other generalizations. This account of necessity leads to a theory of causation according to which events are causally related when (...) there is a mechanism that connects them. I present reasons why the lack of an account of fundamental physical causation does not undermine the mechanical account. (shrink)

Although the historical dispute between introspective psychology and ontological behaviorism encourages the belief that attitudes do not exist, this belief is misguided. Even the Hacking test, suggested by someone with grave doubts about behavioral science, supports the claim that attitudes are “just as real as neutrinos.” Nevertheless, the progress of a science of attitudes may be severely limited by the influence of exogenous factors, factors including normative beliefs about how we should treat the people to whom attitudes are attributed. In (...) so far as these beliefs prevent scientists from experimenting on people and their institutions, particle physics has resources unavailable to survey research. Thus a serious examination of behavioral science leads to some surprising conclusions as to which sciences are the “hard” ones and which ones are simply easier. (shrink)

The philosophical technical term "supervenience" is frequently used in the philosophy of mind as a concise way of characterizing the core idea of physicalism in a manner that is neutral with respect to debates between reductive physicalists and nonreductive physicalists. I argue against this alleged neutrality and side with reductive physicalists. I am especially interested here in debates between psychoneural reductionists and nonreductive functionalist physicalists. Central to my arguments will be considerations concerning how best to articulate the spirit of the (...) idea of supervenience. I argue for a version of supervenience, "fine-grained supervenience," which is the claim that if, at a given time, a single entity instantiates two distinct mental properties, it must do so in virtue of instantiating two distinct physical properties. I argue further that despite initial appearances to the contrary, such a construal of supervenience can be embraced only by reductive physicalists. (shrink)

This paper examines Descartes's third primary notion and the distinction between different kinds of knowledge based on different and mutually irreducible primary notions. It discusses the application of the notions of clearness and distinctness to the domain of knowledge based on that of mind-body union. It argues that the consequences of the distinctions Descartes is making with regard to our knowledge of the human mind and nature are rather different from those that have been attributed to Descartes due to the (...) influential Rylean picture of Cartesian mind-body dualism.

According to Donald Davidson, linguistic meaning is determined by the principle of charity. Because of Davidson's semantic behaviourism, charity's significance is both epistemic and metaphysical: charity not only provides the radical interpreter with a method for constructing a semantic theory on the basis of his data, but it does so because it is the principle metaphysically determining meaning. In this paper, I assume that charity does determine meaning. On this assumption, I investigate both its epistemic and metaphysical status: is charity (...) a priori or a posteriori? And what kind of necessity does it have? According to Davidson himself, charity is an a priori truth and its necessity is conceptual: it is essential to, or constitutive of, our common concepts of meaning and belief. Not only does this generate tension within Davidson's own, Quine-inspired epistemology, but there is independent reason to think of charity as an empirical truth. Even so, charity might be essential to belief and meaning in the sense of being an a posteriori necessity. I conclude that our ordinary modal intuitions might well support charity's psychological-nomological necessity, but that they do not reach all the way to metaphysical necessity. (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)

Probabilism is committed to two theses: 1) Opinion comes in degrees—call them degrees of belief, or credences. 2) The degrees of belief of a rational agent obey the probability calculus. Correspondingly, a natural way to argue for probabilism is: i) to give an account of what degrees of belief are, and then ii) to show that those things should be probabilities, on pain of irrationality. Most of the action in the literature concerns stage ii). Assuming that stage i) has been (...) adequately discharged, various authors move on to stage ii) with varied and ingenious arguments. But an unsatisfactory response at stage i) clearly undermines any gains that might be accrued at stage ii) as far as probabilism is concerned: if those things are not degrees of belief, then it is irrelevant to probabilism whether they should be probabilities or not. In this paper we scrutinize the state of play regarding stage i). We critically examine several of the leading accounts of degrees of belief: reducing them to corresponding betting behavior (de Finetti); measuring them by that behavior (Jeffrey); and analyzing them in terms of preferences and their role in decision-making more generally (Ramsey, Lewis, Maher). We argue that the accounts fail, and so they are unfit to subserve arguments for probabilism. We conclude more positively: ‘degree of belief’ should be taken as a primitive concept that forms the basis of our best theory of rational belief and decision: probabilism. (shrink)

The "relational mind" approach to the inner content of consciousness is developed in terms of various control structures and processing strategies and their possible neurobiological identifications in brain sites. This leads naturally to a division of consciousness into a passive and an active part. A global control structure for the "single strand" aspect of consciousness is proposed as the thalamo-nucleus reticularis thalami-cortex coupled system, which is related to experimental data on the electrical stimulation of awareness. Local control, in terms of (...) excitatory transfer from pre-processing sites to posterior working memory regions, is supported by data on subliminal perception timing and disambiguation of poorly defined percepts. The inner content of consciousness is understood as arising from the resulting relational features between inputs and stored pre-processing and episodic memories. Strong analogies are drawn between emergent properties of the model and suggested properties of "raw feels", supporting the thesis that working memories are the initial sites for the emergence of phenomenal awareness, and the frontal lobes for its further adumbration in terms of higher cognitive processing, including the creation of self.

Online collection of papers by Devitt, Dretske, Guarino, Hochberg, Jackson, Petitot, Searle, Tye, Varzi and other leading thinkers on philosophy and the foundations of cognitive Science. Topics dealt with include: Wittgenstein and Cognitive Science, Content and Object, Logic and Foundations, Language and Linguistics, and Ontology and Mereology.

I sketch an explanatory framework that fits a variety of contemporary research programs in cognitive science. I then investigate the scope and the implications of this framework. The framework emphasizes (a) the explanatory role played by the semantic content of cognitive representations, and (b) the important mechanistic, non-intentional dimension of cognitive explanations. I show how both of these features are present simultaneously in certain varieties of cognitive explanation. I also consider the explanatory role played by grounded representational content, that is, (...) content evaluated by appeal to its truth, falsity, accuracy, inaccuracy and other relational properties.

John McDowell claims that the propositional attitudes, and our conceptual abilities in general, are not appropriate topics for inquiry of the sort that is done in natural science. He characterizes the natural sciences as making phenomena intelligible in terms of their place in the realm of laws of nature. He claims that this way of making phenomena intelligible contrasts crucially with essential features of our understanding of propositional attitudes and conceptual abilities. In this article I show that scientific work of (...) the sort McDowell claims cannot be done is in fact being done, and that this work presents strong evidence that there are psychological laws. The research I discuss is that by the psychologist Norman H. Anderson and his colleagues. I also argue that the considerations McDowell presents in defense of his claims do not constitute a significant challenge to the research that Anderson and his colleagues have done. It will be noted in the article that Anderson's work is relevant not just to McDowell's writings, but also to several much discussed issues in philosophy of cognitive science: the above two issues of whether there can be a science of ordinary psychological phenomena, higher cognition, comparable to that of the natural sciences and whether such a science would present laws, and also the issue of whether in such a science, and its laws, notions of folk psychology would play crucial constitutive roles. Anderson's work presents strong grounds for affirmative answers to all of these questions. (shrink)

In this paper,1 I discuss Davidson’s ideas about the relationship between mind and language. First, I consider his arguments for the claim that there cannot be thought without language, and I examine the assumptions the arguments presuppose. In the second place, I consider the idea of “thought” Davidson adopts, and its essentially normative and holistic character. Third, I try to show the adequacy of this conception of thought in order to deal with epistemological problems, and the inadequacy of this notion (...) in solving the problem of the “emergence” of thought. Finally, I sketch an alternative account of such an “emergence,” looking for continuities between pre-linguistic and linguistic thoughts. (shrink)

How could the fundamental mental operations which facilitate scientific theorizing be the product of natural selection, since it appears that such theoretical methods were neither used nor useful "in the cave"-i.e., in the sequence of environments in which selection took place? And if these wired-in information processing techniques were not selected for, how can we view rationality as an adaptation? It will be the purpose of this paper to address such questions as these, and in the process to sketch some (...) of the considerations that an evolutionary account of rationality may involve. By describing the broad framework within which the evolution of rationality may eventually be understood, I hope to undermine the idea that evolutionary theory is somehow incapable of dealing with this characteristic and requires supplementation by some novel principle. A more modest ambition of the paper is to try to provoke those who think that there are special problems involved in this evolutionary inquiry to say what these problems are. (shrink)

There are arguments which purport to rebut psychological determinism by appealing to its alleged incompatibility with rationality. I argue that they all fail. Against Davidson, I argue that rationality does not preclude the existence of psychological laws. Against Popper, I argue that rationality is compatible with the possibility of predicting human actions. Against Schlesinger, I claim that Newcomb's problem cannot be invoked to show that human actions are unpredictable. Having vindicated the possibility of a rationally-based theory of action, I consider (...) the form it might take. (shrink)

A series of representations must be semantics-driven if the members of that series are to combine into a single thought: where semantics is not operative, there is at most a series of disjoint representations that add up to nothing true or false, and therefore do not constitute a thought at all. A consequence is that there is necessarily a gulf between simulating thought, on the one hand, and actually thinking, on the other. A related point is that a popular doctrine (...) - the so-called 'computational theory of mind' (CTM) - is based on a confusion. CTM is the view that thought-processes consist in 'computations', where a computation is defined as a 'form-driven' operation on symbols. The expression 'form-driven operation' is ambiguous, as it may refer either to syntax-driven operations or to morphology-driven operations. Syntax-driven operations presuppose the existence of operations that are driven by semantic and extra-semantic knowledge. So CTM is false if the terms 'computation' and 'form-driven operation' are taken to refer to syntax-driven operations. Thus, if CTM is to work, those expressions must be taken to refer to morphology-driven operations. CTM therefore fails, given that an operation must be semantics-driven if it is to qualify as a thought. CTM therefore fails on each possible disambiguation of the expressions 'formal operation' and 'computation,' and it is therefore false. (shrink)

This paper argues that the non-reductive monist need not be concerned about the ‘problem’ of mental causation; one can accept both the irreducibility of mental properties to physical properties and the causal closure of the physical. More precisely, it is argued that instances of mental properties can be causally efficacious, and that there is no special barrier to seeing mental properties whose instances are causally efficacious as being causally relevant to the effects they help to bring about. It is then (...) shown that the causal relevance of mental properties is consistent with there being no downward causation, so the dilemma of ‘epiphenomenalism or reduction’ can be avoided. Non-reductive monism lives on as a viable position in the philosophy of mind. (shrink)

There is a considerable effort in current theorizing about psychological phenomena to eliminate minds and selves as a vestige of folk theories. The pertinent strategies are quite varied and may focus on experience, cognition, interests, responsibility, behavior and the scientific explanation of these phenomena or what they purport to identify. The minimal function of the notion of self is to assign experience to a suitable entity and to fix such ascription in a possessive as well as a predicative way. It (...) is usually argued that Hume formulated an empiricist account of experience that obviated the need for reference to selves; and recent arguments mustered by Derek Parfit claim to show how to preserve experience, interest, responsibility usually assigned selves and persons without invoking any such entities. The argument here advanced demonstrates that Hume actually concedes the minimal use of the notion of self, that there appear to be no convincing grounds for eliminating it, that there are critical uses for the notion that render it ineliminable, that admission is neutral regarding the nature of selves, and that Parfit''s arguments in particular fail. There appear, therefore, to be no empiricist or materialist grounds for the eliminative move. A large recent literature that favors various eliminative strategies is canvassed and shown to be inadequate to its task and unlikely (for principled reasons) to be able to achieve its eliminative objective.
