The disjunction problem and the distality problem each presents a challenge that any theory of mental content must address. Here we consider their bearing on purely probabilistic causal theories. In addition to considering these problems separately, we consider a third challenge—that a theory must solve both. We call this “the hard problem.” We consider 8 basic ppc theories along with 240 hybrids of them, and show that some can handle the disjunction problem and some can (...) handle the distality problem, but none can handle the hard problem. This is our main result. We then discuss three possible responses to that result, and argue that though the first two fail, the third has some promise. (shrink)

In her landmark book, Language, Thought, and Other Biological Categories (Millikan1984),1 Ruth Garrett Millikan utilizes the idea of a biological function to solve philosophical problems associated with the phenomena of language, thought, and meaning. Language and thought are activities of biological organisms, according to Millikan, and we should treat them as such when trying to answer related philosophical questions. Of special interest is Millikan’s treatment of intentionality. Here Millikan employs the notion of a biological function to explain what it is (...) for one thing in nature, a bee dance (43), for example, to be about another, in this case, the location of a nectar source. My concern in this paper is to understand whether Millikan’s account of intentionality adequately explains how humans achieve reference, in language or thought, to individuals and groups in their environment. In bringing her theory of intentional content to bear on human activities, Millikan focuses largely on natural language. Thus, in what follows, I begin by laying out the biology-based principles that underlie Millikan’s theory of content, then proceed with an explanation of how the theory is to apply to natural language. As it appears, Millikan’s account of how content is determined for natural language terms and sentences rests on the determinacy of intentional content at the psychological level. This leads me to take a careful look at what Millikan says about the content of mental representations, in hopes of finding a sufficient basis there for the application of Millikan’s theory of content to natural language. Ultimately, I conclude that Millikan’s theory faces a problem of vacuity. If we approach the theory as a theory of intentional content, intended to explain the nature of reference, the theory is lacking in an extremely important respect: Millikan explains how it could be one of the biological functions of a mental or natural language term to refer, without telling us precisely what in the natural order constitutes the reference relation..

This entry surveys a range of proposed solutions to the problem of intentionality, that is, the problem of explaining how human thoughts can be about, or be directed toward, objects. The family of solutions described here takes the content of a mental representation—what that concept represents or is about—to be a function of causal relations between mental representations and their typically external objects. This emphasis on causal relations should be understood broadly, however, so as to (...) cover theories couched in terms of law-like natural relations or the law-governed way in which one natural event carries information about another.

On the dominant interpretation, Ockham is an externalist about mental content. This reading is founded principally on his theory of intuitive cognition. Intuitive cognition plays a foundational role in Ockham’s account of concept formation and judgment, and Ockham insists that the content of intuitive states is determined by the causal relations such states bear to their objects. The aim of this paper is to challenge the externalist interpretation by situating Ockham’s account of intuitive cognition vis-à-vis his (...) broader account of efficient causation. While there can be no doubt that intuitive states are causally individuated, I argue that, given Ockham’s broader theory of efficient causation (on which causation turns out to be an internal relation), this very fact entails that the content of such states is determined by factors internal (rather than external) to the states themselves. (shrink)

It is natural to think that our ordinary practices in giving explanations for our actions, for what we do, commit us to claiming that content properties are causally relevant to physical events such as the movements of our limbs and bodies, and events which these in turn cause. If you want to know why my body ambulates across the street, or why my arm went up before I set out, we suppose I have given you an answer when I (...) say that I wanted to greet a friend on the other side of the street, and thought that my arm's going up would be interpreted by him as a signal to stop for a moment. This widely held view might be disputed, but I shall not argue for it in this paper. I want to start with the view that our beliefs and desires and other propositional attitudes are causally relevant, in virtue of their modes and particular contents, to our movements, in order to investigate the consequences for analyses of thought content. For this purpose, I argue, in sec. II, for three necessary conditions on causal relevance: (a) a nomic sufficiency condition, (b) a logical independence condition, and (c) a screening-off condition. In sec. III, I apply these conditions to relational and functional theories of thought content, arguing that these theories cannot accommodate the causal relevance of content properties to our behaviour. I argue further that, on two plausible assumptions, one about the dependence of the mental on the physical, and the other about the availability in principle of causal explanations of our movements in terms of our non-relational physical properties, content properties can be causally relevant only if they are nomically type-correlated, relative to certain circumstances, with non-relational physical properties of our bodies. In sec. IV, I respond to a number of objections that might be advanced against this conclusion. (shrink)

Externalism is the view that the intentional content of a mental state supervenes on its relations to objects in the extramental world. Nativism is the view that some of the innate states of the mind/brain have intentional content. I consider both “causal” and “nomic” versions of externalism, and argue that both are incompatible with nativism. I consider likely candidates for a compatibilist position – a nativism of “narrow” representational states, and a nativism of the contentless formal (...) “vehicles” of representational states. I argue that “narrow nativism” is either too implausible to appeal to the nativist – because it entails that innate representational states are lost as the mind becomes more experienced, or too costly to appeal to the externalist – because a reasonable version of it requires the analytic-synthetic distinction. Finally, I argue that “syntactic nativism” is indistinguishable from classical anti-nativist empiricism, given the latter’s broad tolerance for innate implementation of psychological principles and mechanisms.

Informational theories of semantic content have been recently gaining prominence in the debate on the notion of mental representation. In this paper we examine new-wave informational theories which have a special focus on cognitive science. In particular, we argue that these theories face four important difficulties: they do not fully solve the problem of error, fall prey to the wrong distality attribution problem, have serious difficulties accounting for ambiguous and redundant representations and fail to deliver (...) a metasemantic theory of representation. Furthermore, we argue that these difficulties derive from their exclusive reliance on the notion of information, so we suggest that pure informational accounts should be complemented with functional approaches.

In this paper, I analyze a type of externalist enactivism defended by Riccardo Manzotti. Such radical versions of enactivism are gaining more attention, especially in cognitive science and cognitive robotics. They are radical in that their notion of representation is purely referential, and content is conflated with reference. Manzotti follows in the footsteps of early causal theories of reference that had long been shown to be inadequate. It is commonly known that radical versions of externalism may lead (...) to difficulties with the notion of representation, especially if they cannot help themselves with the notion of syntax. I argue that a type of externalism present in Manzotti’s enactivism may well lead to anti-representationalism. (shrink)

Contemporary philosophy and theoretical psychology are dominated by an acceptance of content-externalism: the view that the contents of one's mental states are constitutively, as opposed to causally, dependent on facts about the external world. In the present work, it is shown that content-externalism involves a failure to distinguish between semantics and pre-semantics---between, on the one hand, the literal meanings of expressions and, on the other hand, the information that one must exploit in order to ascertain their literal (...) meanings. It is further shown that, given the falsity of content-externalism, the falsity of the Computational Theory of Mind (CTM) follows. It is also shown that CTM involves a misunderstanding of terms such as "computation," "syntax," "algorithm," and "formal truth." Novel analyses of the concepts expressed by these terms are put forth. These analyses yield clear, intuition-friendly, and extensionally correct answers to the questions "what are propositions?, "what is it for a proposition to be true?", and "what are the logical and psychological differences between conceptual (propositional) and non-conceptual (non-propositional) content?" Naively taking literal meaning to be in lockstep with cognitive content, Burge, Salmon, Falvey, and other semantic externalists have wrongly taken Kripke's correct semantic views to justify drastic and otherwise contraindicated revisions of commonsense. (Salmon: What is non-existent exists; at a given time, one can rationally accept a proposition and its negation. Burge: Somebody who is having a thought may be psychologically indistinguishable from somebody who is thinking nothing. Falvey: somebody who rightly believes himself to be thinking about water is psychologically indistinguishable from somebody who wrongly thinks himself to be doing so and who, indeed, isn't thinking about anything.) Given a few truisms concerning the differences between thought-borne and sentence-borne information, the data is easily modeled without conceding any legitimacy to any one of these rationality-dismantling atrocities. (It thus turns out, ironically, that no one has done more to undermine Kripke's correct semantic points than Kripke's own followers!). (shrink)

It is a live possibility that certain of our experiences reliably misrepresent the world around us. I argue that tracking theories of mental representation have difficulty allowing for this possibility, and that this is a major consideration against them.

Radical enactivism, an increasingly influential approach to cognition in general, has recently been applied to memory in particular, with Hutto and Peeters New directions in the philosophy of memory, Routledge, New York, 2018) providing the first systematic discussion of the implications of the approach for mainstream philosophical theories of memory. Hutto and Peeters argue that radical enactivism, which entails a conception of memory traces as contentless, is fundamentally at odds with current causal and postcausal theories, which remain (...) committed to a conception of traces as contentful: on their view, if radical enactivism is right, then the relevant theories are wrong. Partisans of the theories in question might respond to Hutto and Peeters’ argument in two ways. First, they might challenge radical enactivism itself. Second, they might challenge the conditional claim that, if radical enactivism is right, then their theories are wrong. In this paper, we develop the latter response, arguing that, appearances to the contrary notwithstanding, radical enactivism in fact aligns neatly with an emerging tendency in the philosophy of memory: radical enactivists and causal and postcausal theorists of memory have begun to converge, for distinct but compatible reasons, on a contentless conception of memory traces.

Presentation and comparison of the main causal theories of reference for proper names, and a proposal of a new approach based on the analogy of the causal chain of reference with the block chain from blockchain technology and Paul Ricœur's narrative theory. After a brief Introduction in which the types of sentences from the concept of possible worlds are reviewed, and an overview of the theory in the Causal Theory of Reference, I present the causal (...) theory of the reference proposed by Saul Kripke, then two hybrid causal theories developed by Gareth Evans and Michael Devitt.

This paper engages critically with anti-representationalist arguments pressed by prominent enactivists and their allies. The arguments in question are meant to show that the “as-such” and “job-description” problems constitute insurmountable challenges to causal-informational theories of mental content. In response to these challenges, a positive account of what makes a physical or computational structure a mental representation is proposed; the positive account is inspired partly by Dretske’s views about content and partly by the role of (...) mental representations in contemporary cognitive scientific modeling.

From a moral point of view we think of ourselves as capable of responsible actions. From a scientific point of view we think of ourselves as animals whose behaviour, however highly evolved, conforms to natural scientific laws. Natural Agency argues that these different perspectives can be reconciled, despite the scepticism of many philosophers who have argued that 'free will' is impossible under 'scientific determinism'. This scepticism is best overcome, according to the author, by defending a causal theory of action, (...) that is by establishing that actions are constituted by behavourial events with the appropriate kind of mental causal history. He sets out a rich and subtle argument for such a theory and defends it against its critics. Thus the book demonstrates the importance of philosophical work in action theory for the central metaphysical task of understanding our place in nature. (shrink)

Most contemporary philosophers of action accept Aristotle’s view that actions involve movements generated by an internal cause. This is reflected in the wide support enjoyed by the Causal Theory of Action (CTA), according to which actions are bodily movements caused by mental states. Some critics argue that CTA suffers from the Problem of Disappearing Agents (PDA), the complaint that CTA excludes agents because it reduces them to mere passive arenas in which certain events and processes take place. Extant (...) treatments of PDA, most notably those of Michael Bratman and David Velleman, interpret the problem as a challenge to CTA’s ability to capture the role of rational capacities like deliberation and reflection in the etiology of human action. I argue that PDA admits of another interpretation, one that arises when we appreciate that the exercise of higher rational capacities in action presupposes possession of a prior lower-level capacity for basic self-movement – the power to initiate and control one’s bodily behavior. Bolstering CTA so that it accommodates richer exercises of practical thought – as Bratman and Velleman do – will not resolve PDA unless CTA already captures this basic agential power. Adequately responding to PDA, therefore, requires answering a question unaddressed by current responses: How do bodily movements caused by sub-agential items like mental states count as movements actively performed by the whole agent? I argue that CTA can answer this question by adopting a normative account of the nature of self-moving agents. On this view, self-moving agents are teleologically constituted, meaning (1) their nature and proper function derives from their characteristic ends and aims, and (2) the nature and proper function of their parts depend on these ends and aims. Basic self-movement consists of movements caused by a sub-agential part whose own proper function is to generate behavior that constitutes or contributes to the pursuit of the agent’s overall proper function. After showing how this picture applies to artifactual and collective agents (i.e., robots and teams), I extend the account to organic agents (human beings) by sketching a broadly Aristotelian picture of the nature of living things.

Illusionists about consciousness boldly argue that phenomenal consciousness does not fundamentally exist — it only seems to exist. For them, the impression of having a private inner life of conscious qualia is nothing more than a cognitive error, a conjuring trick put on by a purely physical brain. Some phenomenal realists have accused illusionism of being a byproduct of modern Western scientism and overzealous naturalism. However, Jay Garfield has endorsed illusionism by explicitly drawing support from the classical Yogācāra Buddhist philosopher (...) Vasubandhu. In this paper, I assess the degree to which Garfield’s illusionist interpretation accurately captures the views of Vasubandhu and his commentator Sthiramati in their extant Sanskrit works. As it turns out, Vasubandhu and Sthiramati converge with contemporary illusionists in taking an unconscious causal basis of cognitive/linguistic processes to be responsible for generating the illusion of representational states with apparently phenomenal contents. Within their constitutive understanding of the mind as the “imagination of what is non-existent” (abhūtaparikalpa), I raise possible candidates for what might seem to be real instances of phenomenality — mental appearances (pratibhāsa), affective sensory experience (vedanā), and “intrinsic luminosity” (prakṛtiprabhāsvara) — and consider possible responses on behalf of an illusionist interpreter. I conclude that Vasubandhu and Sthiramati really do appear to be strong illusionists about phenomenal consciousness, particularly if phenomenal states are assumed to be essentially representational.

In order to fulfil their essential roles as the bearers of truth and the relata of logical relations, propositions must be public and shareable. That requirement has favoured Platonist and other nonmental views of them, despite the well-known problems of Platonism in general. Views that propositions are mental entities have correspondingly fallen out of favour, as they have difficulty in explaining how propositions could have shareable, objective properties. We revive a mentalist view of propositions, inspired by Artificial Intelligence work (...) on perceptual algorithms, which shows how perception causes persistent mental entities with shareable properties that allow them to fulfil the traditional roles of (one core kind of) propositions. The clustering algorithms implemented in perception produce outputs which are (implicit) atomic propositions in different minds. Coordination of them across minds proceeds by game-theoretic processes of communication. The account does not rely on any unexplained notions such as mental content, representation, or correspondence (although those notions are applicable in philosophical analysis of the result).

Episodic memory (memories of the personal past) and prospecting the future (anticipating events) are often described as mental time travel (MTT). While most use this description metaphorically, we argue that episodic memory may allow for MTT in at least some robust sense. While episodic memory experiences may not allow us to literally travel through time, they do afford genuine awareness of past-perceived events. This is in contrast to an alternative view on which episodic memory experiences present past-perceived events as (...) mere intentional contents. Hence, episodic memory is a way of coming into experiential contact with, or being again aware of, what happened in the past. We argue that episodic memory experiences depend on a causal-informational link with the past events being remembered, and that, assuming direct realism about episodic memory experiences, this link suffices for genuine awareness. Since there is no such link in future prospection, a similar argument cannot be used to show that it also affords genuine awareness of future events. Constructivist views of memory might challenge the idea of memory as genuine awareness of remembered events. We explain how our view is consistent with both constructivist and anti-causalist conceptions of memory. There is still room for an interpretation of episodic memory as enabling genuine awareness of past events, even if it involves reconstruction. (shrink)

Sophisticated dispositionalism proposes a naturalist reduction of mental content by claiming that the semantic content of a mental symbol is determined by the causes of the occurrence of this symbol under ideal conditions, i.e., conditions under which only the referent of a symbol can cause its tokening. However, Paul Boghossian developed the open-endedness objection in order to show that it is not possible to specify these ideal conditions in non-semantic terms, entailing that the naturalist reduction of (...) mental content proposed by sophisticated dispositionalism is not viable. My goal in this paper is to argue that the open-endedness objection is flawed. (shrink)

Among the cognitive capacities of evolved creatures is the capacity to represent. Theories in cognitive neuroscience typically explain our manifest representational capacities by positing internal representations, but there is little agreement about how these representations function, especially with the relatively recent proliferation of connectionist, dynamical, embodied, and enactive approaches to cognition. In this talk I sketch an account of the nature and function of representation in cognitive neuroscience that couples a realist construal of representational vehicles with a pragmatic account (...) of mental content. I call the resulting package a deflationary account of mental representation and I argue that it avoids the problems that afflict competing accounts. (shrink)

Our pains can be more or less intense, our mental imagery can be more or less vivid, our perceptual experiences can be more or less striking. These degrees of intensity of conscious experiences are all manifestations of a phenomenal property I call mental strength. In this article, I argue that mental strength is a domain-general phenomenal magnitude; in other words, it is a phenomenal quantity shared by all conscious experiences that explains their degree of felt intensity. (...) class='Hi'>Mental strength has been largely overlooked in favor of mental states’ type, representational contents, domain-specific phenomenology, or processes such as attention. Considering mental strength in our reflections about the mind illuminates debates about the relation of representational contents and phenomenal character, and it also helps address questions about the structure and functions of consciousness. Mental strength provides a unifying construct to model what is shared in the phenomenology of different types of conscious experiences. (shrink)

I develop several new arguments against claims about "cognitive phenomenology" and its alleged role in grounding thought content. My arguments concern "absent cognitive qualia cases", "altered cognitive qualia cases", and "disembodied cognitive qualia cases". However, at the end, I sketch a positive theory of the role of phenomenology in grounding content, drawing on David Lewis's work on intentionality. I suggest that within Lewis's theory the subject's total evidence plays the central role in fixing mental content and (...) ruling out deviant interpretations. However I point out a huge unnoticed problem, the problem of evidence: Lewis really has no theory of sensory content and hence no theory of what fixes evidence. I suggest a way of plugging this hole in Lewis's theory. On the resulting theory, which I call " phenomenal functionalism", there is a sense in which sensory phenomenology is the source of all determinate intentionality. Phenomenal functionalism has similarities to the theories of Chalmers and Schwitzgebel. (shrink)

In psychiatry, pharmacological drugs play an important experimental role in attempts to identify the neurobiological causes of mental disorders. Besides being developed in applied contexts as potential treatments for patients with mental disorders, pharmacological drugs play a crucial role in research contexts as experimental instruments that facilitate the formulation and revision of neurobiological theories of psychopathology. This paper examines the various epistemic functions that pharmacological drugs serve in the discovery, refinement, testing, and elaboration of neurobiological theories (...) of mental disorders. I articulate this thesis with reference to the history of antipsychotic drugs and the evolution of the dopamine hypothesis of schizophrenia in the second half of the twentieth century. I argue that interventions with psychiatric patients through the medium of antipsychotic drugs provide researchers with information and evidence about the neurobiological causes of schizophrenia. This analysis highlights the importance of pharmacological drugs as research tools in the generation of psychiatric knowledge and the dynamic relationship between practical and theoretical contexts in psychiatry.

I defend a theory of mental representation that satisfies naturalistic constraints. Briefly, we begin by distinguishing (i) what makes something a representation from (ii) given that a thing is a representation, what determines what it represents. Representations are states of biological organisms, so we should expect a unified theoretical framework for explaining both what it is to be a representation as well as what it is to be a heart or a kidney. I follow Millikan in explaining (i) in (...) terms of teleofunction, explicated in terms of natural selection. -/- To explain (ii), we begin by recognizing that representational states do not have content, that is, they are neither true nor false except insofar as they both “point to” or “refer” to something, as well as “say” something regarding whatever it is they are about. To distinguish veridical from false representations, there must be a way for these separate aspects to come apart; hence, we explain (ii) by providing independent theories of what I call f-reference and f-predication (the ‘f’ simply connotes ‘fundamental’, to distinguish these things from their natural language counterparts). -/- Causal theories of representation typically founder on error, or on what Fodor has called the disjunction problem. Resemblance or isomorphism theories typically founder on what I’ve called the non-uniqueness problem, which is that isomorphisms and resemblance are practically unconstrained and so representational content cannot be uniquely determined. These traditional problems provide the motivation for my theory, the structural preservation theory, as follows. F-reference, like reference, is a specific, asymmetric relation, as is causation. F-predication, like predication, is a non-specific relation, as predicates typically apply to many things, just as many relational systems can be isomorphic to any given relational system. Putting these observations together, a promising strategy is to explain f-reference via causal history and f-predication via something like isomorphism between relational systems. -/- This dissertation should be conceptualized as having three parts. After motivating and characterizing the problem in chapter 1, the first part is the negative project, where I review and critique Dretske’s, Fodor’s, and Millikan’s theories in chapters 2-4. Second, I construct my theory about the nature of representation in chapter 5 and defend it from objections in chapter 6. In chapters 7-8, which constitute the third and final part, I address the question of how representation is implemented in biological systems. In chapter 7 I argue that single-cell intracortical recordings taken from awake Macaque monkeys performing a cognitive task provide empirical evidence for structural preservation theory, and in chapter 8 I use the empirical results to illustrate, clarify, and refine the theory.

I clarify some of the details of the modal theory of function I outlined in Nanay (2010): (a) I explicate what it means that the function of a token biological trait is fixed by modal facts; (b) I address an objection to my trait type individuation argument against etiological function and (c) I examine the consequences of replacing the etiological theory of function with a modal theory for the prospects of using the concept of biological function to explain mental (...) content.

Introduction: representationalismMost theorists of cognition endorse some version of representationalism, which I will understand as the view that the human mind is an information-using system, and that human cognitive capacities are representational capacities. Of course, notions such as ‘representation’ and ‘information-using’ are terms of art that require explication. As a first pass, representations are “mediating states of an intelligent system that carry information” (Markman and Dietrich 2001, p. 471). They have two important features: (1) they are physically realized, and so (...) have causal powers; (2) they are intentional, in other words, they have meaning or representational content. This presumes a distinction between a representational vehicle—a physical state or structure that has causal powers and is responsible for producing behavior—and its content. Consider the following characterization of a device that computes the addition functionReaders will recognize the similarity t. (shrink)

Like all causal theories in philosophy, the causal theory of action is plagued by the problem of deviant causal chains. I have proposed a solution on the basis of the assumption that mental states and events are causally efficacious in virtue of their contents. This solution has been questioned by Torbjörn Tännsjö (2009). First, I will reply to the objection, and then I will discuss Tännsjö’s alternative.

It can be hard to see where money fits in the world. Money seems both real and imaginary, since it has obvious causal powers, but is also, just as obviously, something humans have just made up. Recent philosophical accounts of money have declared it to be real, but for very different reasons. John Searle and Francesco Guala disagree over whether money is just whatever acts like money, or just whatever people believe to be money. In developing their accounts of (...) institutions as a part of social reality, each uses money as a paradigm institution, but they disagree on how institutions exist. Searle argues that the institution of money belongs to an ontological level separate from the physical world, held up by the collective intentions of a group, while Guala claims that money is a part of the ordinary physical world and is just whatever performs a “money-like function” in a group, regardless of what that group believes about it. Here, we argue that any purely functional account like Guala’s will be unable to capture the distinctive phenomenon of money, since monetary transactions are defined by the attitudes transactors hold toward them. Money will be obscured or misidentified if defined functionally. As we go on to show by examining recent work by Smit et al., belief in money does not require taking on all of Searle’s ontological commitments, but money and mental contents will stand or fall together.

Grounding-theoretic reformulation of Fodor's theory of content that addresses recalcitrant Quinean concerns.

ABSTRACT -/- A propositional attitude (PA) is a belief, desire, fear, etc., that x is the case. This dissertation addresses the question of the semantic content of a specific kind of PA-instance: an instance of a belief of the form all Fs are Gs. The belief that all bachelors are sports fans has this form, while the belief that Spain is a country in Eastern Europe do not. Unlike a state of viewing the color of an orange, a belief-instance (...) is semantically contentful because it has reference, a meaning, logical implications, or a truth-value. While the intrinsic semantics view holds that either concepts or abstract objects are the source of content for PAs, the extrinsic semantics view holds that symbols of a mental language provide this content. I argue that a successful theory of intentionality must explain: (1) the truth-preserving causal powers of PAs, (2) the failure of the deductive principle Substitutivity to preserve truth over sentences that ascribe PAs, and (3) the truth-evaluability of PAs. As an internalist version of the extrinsic semantics view, I first evaluate Fodor’s Computational Theory of Mind, which says the semantic ingredients of mental states are symbols governed by rules of a mental syntax. I argue that in order to meet (1), CTM would have to associate the causal patterns of each thought-type with the inferential relations of some proposition – in an arbitrary or question-begging way. I also evaluate Fodor’s causal theory, as an externalist version of the extrinsic semantics view. This view is that lawlike causal relations between mental symbols and objects determine the reference, and thus the truth-value, of a thought. I argue that Brian Loar’s circularity objection refutes the ability of this theory to meet (3); and I endorse the intrinsic semantics perspective. I evaluate Frege’s theory of abstract, mind-external, and intrinsically semantic objects (senses), as an attempt to meet condition (2). I conclude that mind-external universals are the source of the intrinsically semantic features of concepts. Finally, I put forth a theory called ‘Bare Property Intentionality’, which describes the features of intrinsically representative and semantic concepts that connect them to these universals.

Some of the oldest and deepest questions in philosophy fall under the umbrella of consciousness and mind: What is the mind and how is it related to the body? What provides our thoughts with content? How is consciousness related to the natural world? Do we have distinctive causal powers? Analytic philosophers have made significant progress on these and related problems in the last century. Given the high volume of work on such topics, this chapter is necessarily selective. It (...) offers major touchstones but is slanted in favor of work that touches base with the sciences. The chapter starts by describing the progression of thought on the mind-body problem, from dualism and behaviorism to non-reductive materialism. It then describes the problem of intentionality, with a focus on partial solutions from Dretske and Millikan, ending with a brief discussion of 4E theories of mental content. The section on the problem of consciousness starts with the well-known knowledge and modal arguments before describing some attempted initial solutions, such as eliminative materialism and panpsychism. Finally, there is a brief section on agency and free will, which focuses on the link between free will and consciousness. (shrink)

The received view in physicalist philosophy of mind assumes that causation can only take place at the physical domain and that the physical domain is causally closed. It is often thought that this leaves no room for mental states qua mental to have a causal influence upon the physical domain, leading to epiphenomenalism and the problem of mental causation. However, in recent philosophy of causation there has been growing interest in a line of thought that can (...) be called causal antifundamentalism: causal notions cannot play a role in physics, because the fundamental laws of physics are radically different from causal laws. Causal anti-fundamentalism seems to challenge the received view in physicalist philosophy of mind and thus raises the possibility of there being genuine mental causation after all. This paper argues that while causal anti-fundamentalism provides a possible route to mental causation, we have reasons to think that it is incorrect. Does this mean that we have to accept the received view and give up the hope of genuine mental causation? I will suggest that the ontological interpretation of quantum theory provides us both with a view about the nature of causality in fundamental physics, as well as a view how genuine mental causation can be compatible with our fundamental (quantum) physical ontology.

This paper is an attempt to present a Kripkean (Causal) picture of Reference where the cognitive content in fixing reference plays a vital role. It also points out that Kripke is not a pure causal theorist. By introducing Thomas Kuhn and his theory on vulnerability of the rigid designation, I have shown that there is a danger for causal theory of reference. However Kuhn’s argument fails to have an impact if a Knowledge aspect is augmented to (...) Kripkean theory of reference. This new causal theory of reference preserves the truth of the referential term in spite of the vulnerability of the rigid designation and problem of reference change. It can also adequately answer the question of theoretical terms reference failure. (shrink)

I argue for a possible Buddhist theory of free will that combines Frankfurt's hierarchical analysis of meta-volitional/volitional accord with elements of the Buddhist eightfold path that prescribe that Buddhist aspirants cultivate meta-volitional wills that promote the mental freedom that culminates in enlightenment, as well as a causal/functional analysis of how Buddhist meditative methodology not only plausibly makes that possible, but in ways that may be applied to undermine Galen Strawson's impossibility argument, along with most of the other major (...) arguments for free will skepticism.

Relationalists about episodic memory must endorse a disjunctivist theory of memory-experience according to which cases of genuine memory and cases of total confabulation involve distinct kinds of mental event with different natures. This paper is concerned with a pair of arguments against this view, which are analogues of the ‘causal argument’ and the ‘screening off argument’ that have been pressed in recent literature against relationalist (and hence disjunctivist) theories of perception. The central claim to be advanced is (...) that to deal with these two arguments, memory disjunctivists both can and should draw on resources that are standardly appealed to by rival common factor theories of episodic memory, and, in particular, to the idea that genuine memories and merely apparent ones are to be distinguished, at least in part, in terms of the distinctive ways in which they are caused. On the proposed view, there are substantive causal constraints associated both with cases of genuine memory and with cases of mere confabulation. The resulting theory thus tells us something important about the nature both of genuine memories and of mere confabulations, namely, that such experiences must be caused in certain distinctive ways and cannot occur except as the result of a distinctive sort of causal process. In addition, the theory enables the disjunctivist to offer a unified response to an important pair of arguments against her view. (shrink)

This thesis explores the possibility of theoretically conceiving consciousness as an activity of the brain. Objections, based on the concept of qualia, to the identification of consciousness with a brain activity are refuted. Phenomenal consciousness is identified with access-consciousness. Consciousness is conceived as a higher order processing of informational states of the brain. The state of consciousness represents an integration of prior nonconscious states. Libet’s research on the timing of conscious experience is reviewed and analyzed. His hypothesis of backward referral (...) is rejected. Since specific brain activity (the readiness potential) precedes the conscious intention, the implications of this fact on the concepts of volition and free will are discussed. Non-deliberate voluntary acts are performed without a prior consciousness of the intention to perform them. Conversely, the decision to perform a deliberate act is influenced by consciousness of the intention. Free will is viewed as compatible with the causal determination of mental processes. The theory is successfully applied to the different contents of consciousness: consciousness of perceptions, of bodily sensations, of actions, of memories, of ideas, of thoughts, of language, of affective states, of beliefs, of desires, of oneself and consciousness of being conscious. The relation between the theory of consciousness and psychoanalysis is also explored. Psychoanalysis is seen as compatible with the proposed theory, which is able to enlighten some aspects of the process of becoming conscious in psychoanalytic treatment. The general approach is interdisciplinary : the theory must take into account constraints derived from philosophy, neurophysiology, psychology, neuropsychology, etc. Consciousness is conceived, not as a property of some mental states, but as a specific higher-order activity, based on lower-order nonconscious activities.

We develop a new version of the causal theory of spacetime. Whereas traditional versions of the theory seek to identify spatiotemporal relations with causal relations, the version we develop takes causal relations to be the grounds for spatiotemporal relations. Causation is thus distinct from, and more basic than, spacetime. We argue that this non-identity theory, suitably developed, avoids the challenges facing the traditional identity theory.

In this work, it is shown that given a correct understanding of the nature of reference and of linguistic meaning generally, it is possible to produce non-revisionist analyses of the nature of -/- *Perceptual content, *Mental content generally, *Logical equivalence, *Logical dependence generally, *Counterfactual truth, *The causal efficacy of mental states, and *Our knowledge of ourselves and of the external world. -/- In addition, set-theoretic interpretations of several semantic concepts are put forth. These concepts include (...) truth, falsehood, negation, and conjunction. (shrink)

Is there such a thing as mental causation? Is it possible for the mental to have causal influence on the physical? Or has the old “mind over matter” question been rendered obsolete by the advent of brain science? Whatever our answers to these questions, it seems that we cannot systematically pursue them without considering what makes mental causation problematic in the first place: The causal closure of the physical world. This paper revisits the problem of (...) mental causation by drawing on a classical debate between Dharmakirti and the Indian materialists. The main argument of the paper is that expanding our conception of causality to accommodate phenomenal content can cast new light on the problem of mental causation. A satisfactory solution to the problem of mental causation must reject the completeness of the physical principle in favor of conceptions of causality that allow for phenomenal properties to play a causal-explanatory function.

This paper is about the causal exclusion argument against non-reductive physicalism. Many philosophers think that this argument poses a serious problem for non-reductive theories of the mind — some think that it is decisive against them. In the first part I will outline non-reductive physicalism and the exclusion argument. Then I will distinguish between three versions of the argument that address three different versions of non-reductive physicalism. According to the first, the relation between mental and physical events (...) is token-identity. According to the second, mental events are distinct from physical events, but the latter metaphysically include and determine the former. And on the third version, mental and physical events are entirely distinct. I will argue that the causal exclusion argument is not decisive against non-reductive physicalism in any of the three versions. According to non-reductive physicalism, mental events are dependent on physical events. Causal exclusion and overdetermination, however, requires distinct and independent causes. I will argue that the burden of proof lies with the opponents of non-reductive physicalism, who have to explain how metaphysically dependent events can possibly overdetermine an effect or exclude each other from being causally efficacious.

Perception is riddled with cases of reliable misperception. These are cases in which a perceptual state is tokened inaccurately any time it is tokened under normal conditions. On the face of it, this fact causes trouble for theories that provide an analysis of perceptual content in non-semantic, non-intentional, and non-phenomenal terms, such as those found in Millikan (1984), Fodor (1990), Neander (2017), and Schellenberg (2018). I show how such theories can be extended so that they cover such (...) cases without giving up their core commitments. (shrink)

The present dissertation concerns cognitive psychology—theories about the nature and mechanism of perception and thought—during the High Middle Ages (1250–1350). Many of the issues at the heart of philosophy of mind today—intentionality, mental representation, the active/passive nature of perception—were also the subject of intense investigation during this period. I provide an analysis of these debates with a special focus on Durand of St.-Pourçain, a contemporary of John Duns Scotus and William of Ockham. Durand was widely recognized as a (...) leading philosopher until the advent of the early modern period, yet his views have been largely neglected in the last century. The aim of my dissertation, then, is to provide a new understanding of Durand’s cognitive psychology and to establish a better picture of developments in cognitive psychology during the period. -/- Most philosophers in the High Middle Ages held, in one form or another, the thesis that most forms of cognition (thought, perception) involve the reception of the form of the object into the mind. Such forms in the mind explain what a given episode of cognition is about, its content. According to what has been called the conformality theory of content, the content of our mental states is fixed by this form in the mind. Durand rejects this thesis, and one of the primary theses that I pursue is that Durand replaces the conformality theory of content with a causal theory of content, according to which the content of our mental states is fixed by its cause. When I think about Felix and not Graycat, this is to be explained not by the fact that I have in my mind the form of Felix and not Graycat, but rather by the fact that Felix and not Graycat caused my thought. -/- This is both a controversial interpretation and, indeed, a controversial theory. It is a controversial interpretation because Durand seems to reject the thesis that objects are the causes of our mental states. In the first half of the present dissertation, I argue that Durand does not reject this thesis but he rejects another nearby thesis: that objects as causes give to us ‘forms’. On Durand’s view, an object causes a mental state even though it does not give to us a new ‘form’. In the second half of the dissertation I defend Durand’s causal theory of content against salient objections to it. (shrink)

The goal of this paper is to present some advantages of the representational and computational theories of mind when compared to other views, especially behaviorism. The idea is that representational and computational theories allow us to conceive propositional attitudes in a way that preserves two essential features we take them to have in common sense psychological explanations: semantic evaluability and causal efficacy. Behaviorism reconceives mental states in a way that doesn’t preserve these essential features. In so (...) doing, it makes a mystery of the success of common sense psychology. I illustrate some of the difficulties that behaviorism faces by considering and criticizing Wittgenstein’s approach to linguistic understanding. The upshot is that representational and computational theories of mind do a better job at vindicating common sense psychology, and so are to be preferred when compared to behaviorism. (shrink)

I argue that the familiar picture of the rise of analytic philosophy through the early work of G. E. Moore and Bertrand Russell is incomplete and to some degree erroneous. Archival evidence suggests that a considerable influence on Moore, especially evident in his 1899 paper ‘The nature of judgment,’ comes from the literature in nineteenth-century empirical psychology rather than nineteenth-century neo-Hegelianism, as is widely believed. I argue that the conceptual influences of Moore’s paper are more likely to have had their (...) source in the work of two of Moore’s teachers, G. F. Stout and James Ward. What may be called an anti-psychologism about psychology characterizes the work of these and other psychologists of the period. I argue that the anti-psychologism that is the main aim of Moore’s early theory of judgment is an adaptation of this notion, which is significantly dissimilar from the notion defended by Bradley, traditionally thought to have been a key influence on Moore.Keywords: G. E. Moore; Bertrand Russell; Propositions; Anti-psychologism; Early analytic philosophy; G. F. Stout. (shrink)

Although Hume appeals to the representational features of perceptions in many arguments in the Treatise, his theory of representation has traditionally been regarded as a weak link in his epistemology. In particular, it has proven difficult to reconcile Hume's use of representation as causal derivation and resemblance (the Copy Principle) with his use of representation in the context of impressions and abstract ideas. This paper offers a unified interpretation of representation in Hume that draws on the resources of Berkeley's (...) doctrine of signs. On this account, while the Copy Principle still occupies the core of Hume's "content empiricism," the manner in which any perception represents is understood as involving a relation of sign to thing signified. A sign/signified interpretation has the virtue of allowing Hume to remain within the strictures of his empiricism, while underwriting the various senses in which an impression or idea could possess content. Such an interpretation is not only adequate to account for the role that mental representations play in everyday behavior, but also for the purposes of elaborating the foundations of civil society that are Hume's concern in Book 3 of the Treatise.

The Computational Theory of Mind (CTM) holds that cognitive processes are essentially computational, and hence computation provides the scientific key to explaining mentality. The Representational Theory of Mind (RTM) holds that representational content is the key feature in distinguishing mental from non-mental systems. I argue that there is a deep incompatibility between these two theoretical frameworks, and that the acceptance of CTM provides strong grounds for rejecting RTM. The focal point of the incompatibility is the fact that (...) representational content is extrinsic to formal procedures as such, and the intended interpretation of syntax makes no difference to the execution of an algorithm. So the unique 'content' postulated by RTM is superfluous to the formal procedures of CTM. And once these procedures are implemented in a physical mechanism, it is exclusively the causal properties of the physical mechanism that are responsible for all aspects of the system's behaviour. So once again, postulated content is rendered superfluous. To the extent that semantic content may appear to play a role in behaviour, it must be syntactically encoded within the system, and just as in a standard computational artefact, so too with the human mind/brain - it's pure syntax all the way down to the level of physical implementation. Hence 'content' is at most a convenient meta-level gloss, projected from the outside by human theorists, which itself can play no role in cognitive processing. (shrink)

This chapter will argue that the criminal law is most compatible with a specific theory regarding the mind/body relationship: non-eliminative reductionism. Criminal responsibility rests upon mental causation: a defendant is found criminally responsible for an act where she possesses certain culpable mental states (mens rea under the law) that are causally related to criminal harm. If we assume the widely accepted position of ontological physicalism, which holds that only one sort of thing exists in the world – physical (...) stuff – non-eliminative reductive physicalism about the mind offers the most plausible account of the full-bodied mental causation criminal responsibility requires. Other theories of the mind/body relationship, including elminativism and non-reductive physicalism, threaten criminal responsibility because they do not offer satisfactory accounts of mental causation. Eliminativism, as the name implies, eliminates the mental or is skeptical that it can do the causal work necessary to responsibility; and non-reductive theories disconnect the mental from the physical/casual world such that the mental can no longer have reliable causal effects.

A uniform theory of conditionals is one which compositionally captures the behavior of both indicative and subjunctive conditionals without positing ambiguities. This paper raises new problems for the closest thing to a uniform analysis in the literature (Stalnaker, Philosophia, 5, 269–286 (1975)) and develops a new theory which solves them. I also show that this new analysis provides an improved treatment of three phenomena (the import-export equivalence, reverse Sobel-sequences and disjunctive antecedents). While these results concern central issues in the study (...) of conditionals, broader themes in the philosophy of language and formal semantics are also engaged here. This new analysis exploits a dynamic conception of meaning where the meaning of a symbol is its potential to change an agent’s mental state (or the state of a conversation) rather than being the symbol’s content (e.g. the proposition it expresses). The analysis of conditionals is also built on the idea that the contrast between subjunctive and indicative conditionals parallels a contrast between revising and consistently extending some body of information.

Elements of Mind (EM) has two themes, one major and one minor. The major theme is intentionality, the mind’s direction upon its objects; the other is the mind–body problem. I treat these themes separately: chapters 1, and 3–5 are concerned with intentionality, while chapter 2 is about the mind–body problem. In this summary I will first describe my view of the mind–body problem, and then describe the book’s main theme. Like many philosophers, I see the mind–body problem as containing two (...) sub–problems: the problem of mental causation and the problem of consciousness. I see these problems forming the two horns of a dilemma. Just as the problem of mental causation pushes us towards physicalism, so the problem of consciousness pushes us away from it. Each problem reveals the inadequacy of the solution to the other. Essentially the problem of mental causation is the conflict between (i) the apparent fact that mental states and events have effects in the physical world and (ii) a general principle about the causal nature of the physical world, which is sometimes called the ‘causal closure’ or the ‘causal completeness’ of the physical world. This principle says that all physical effects have physical causes which are enough to bring them about. The problem then is simple: how can a mental cause have a physical effect if that effect also has a physical cause which is enough to bring it about? Barring massive overdetermination of our actions by independent causes, it seems that the best answer is to identify the mental and the physical causes. And this is traditionally how physicalists have argued for their identity theory of mind and body. However, many physicalists reject the identity theory, and therefore they have to solve the mental causation problem in some other way. At present, there is no consensus among physicalists on which of the currently proposed solutions is correct. In chapter 2 of EM I propose an alternative, which I call ‘emergentism’. Inspired by the rejection of the identity theory, Emergentism is the idea that mental properties are genu.. (shrink)

The dominant theory of judgment in 1870 was one or other variety of combination theory: the act of judgment is an act of combining concepts or ideas in the mind of the judging subject. In the decades to follow a succession of alternative theories arose to address defects in the combination theory, starting with Bolzano’s theory of propositions in themselves, Brentano’s theory of judgment as affirmation or denial of existence, theories distinguishing judgment act from judgment content advanced (...) by Brentano’s students Twardowski, Husserl and Meinong, and finally, Adolf Reinach’s addition of a linguistic dimension to the Brentano-Husserlian theory of judgment – an account of judgments as ways of doing things with words in what Reinach called ‘social acts’.
