Just as bodily actions are things you do with your body, mental actions are things you do with your mind. Both are different from things that merely happen to you. Where does the idea of mental action come from? What are mental actions? And why do they matter in philosophy? These are the three main questions answered in this paper. Section 1 introduces mental action through a brief history of the topic in philosophy. Section 2 explains what it is to (...) be a mental action in terms of intentional action. Section 3 argues that the fact that we can perform mental actions has some striking consequences concerning mental content. Section 4 shows how mental action helps to explain some important facts about self-knowledge and the normativity of thought. The conclusion mentions two further fruitful avenues for philosophical research on mental action. (shrink)

Our successful engagement with the world is plausibly underwritten by our sensitivity to affordances in our immediate environment. The considerable literature on affordances focuses almost exclusively on affordances for bodily actions such as gripping, walking or eating. I propose that we are also sensitive to affordances for mental actions such as attending, imagining and counting. My case for this ‘Mental Affordance Hypothesis’ is motivated by a series of examples in which our sensitivity to mental affordances mirrors our sensitivity to bodily (...) affordances. Specifically, subjects perceive opportunities to perform a mental action and their doing so leads, under the right conditions, to the automatic preparation of that action. I conclude by sketching a mental affordance research program that would reinforce my case for the Mental Affordance Hypothesis and establish its ramifications for a number of debates across philosophy and psychology.

Some mental states seem to be "of" or "about" things, or to "say" something. For example, a thought might represent that grass is green, and a visual experience might represent a blue cup. This is intentionality. The aim of this book is to explain this phenomenon. -/- Once we understand intentionality as a phenomenon to be explained, rather than a posit in a theory explaining something else, we can see that there are glaring empirical and in principle difficulties with currently (...) popular tracking and functional role theories of intentionality, which aim to account for intentionality in terms of tracking relations and functional roles. -/- This book develops an alternative theory, the phenomenal intentionality theory (PIT), on which the source of intentionality is none other than phenomenal consciousness, the subjective, felt, or qualitative aspect of mental life. While PIT avoids the problems that plague tracking and functional role theories, it faces its own challenges in accounting for the rich and complex contents of thoughts and the contents of nonconscious states. In responding to these challenges, this book proposes a novel version of PIT, on which all intentionality is phenomenal intentionality, though we in some sense represent many non-phenomenal contents by ascribing them to ourselves. This book further argues that phenomenal consciousness is an intrinsic feature of mental life, resulting in a view that is radically internalistic in spirit: Our phenomenally represented contents are literally in our heads, and any non-phenomenal contents we in some sense represent are expressly targeted by us.

A classical work on Gestalt psychology from a member of the "Berlin School." Discusses perception in relation to the environment, along with action, learning, memory, and socieity.

This essay argues that current theories of action fail to explain agentive control because they have left out a psychological capacity central to control: attention. This makes it impossible to give a complete account of the mental antecedents that generate action. By investigating attention, and in particular the intention-attention nexus, we can characterize the functional role of intention in an illuminating way, explicate agentive control so that we have a uniform explanation of basic cases of causal deviance in action as (...) well as other defects of agency, explain cases of skilled agency and sharpen questions about the role of thought in agency. This provides for a different orientation in the theory of action. (shrink)

Tim Crane maintains that beliefs cannot be conscious because they persist in the absence of consciousness. Conscious judgments can share their contents with beliefs, and their occurrence can be evidence for what one believes; but they cannot be beliefs, because they don’t persist. I challenge Crane’s premise that belief attributions to the temporarily unconscious are literally true. To say of an unconscious agent that she believes that p is like saying that she sings well. To say she sings well is (...) to say that when she sings, her singing is good. To say that she believes that p is to say that when she consciously considers the content that p she consciously affirms it. I also argue that the phenomenal view of intentional content Crane appears to endorse prima facie commits him to the view, at least controversial, perhaps incoherent, that there is unconscious phenomenology. Keywords : Belief; Consciousness; Unconscious; Intentional Content; Judgment. Credenze coscienti Riassunto: Tim Crane sostiene che le credenze non possano essere coscienti, dal momento che perdurano anche in assenza di coscienza. I giudizi formulati consapevolmente possono condividere i loro contenuti con le credenze e il loro verificarsi può essere una forma di evidenza a supporto di quanto uno crede. E tuttavia essi non possono essere credenze, dal momento che non perdurano. Nel commento metto in discussione la premessa di Crane secondo cui porre l’attribuzione di credenze su un piano temporaneamente inconscio sia vero in senso letterale. Dire di un agente non cosciente che esso creda che p è come dire che canti bene. Dire che canti bene è dire che quando canta, il suo canto è buono. Dire che crede che p è dire che quando considera consapevolmente il contenuto p costui lo afferma consapevolmente. Inoltre intendo affermare che la visione fenomenica del contenuto intenzionale che Crane sembra abbracciare lo impegni prima facie nei confronti della prospettiva, quantomeno controversa e probabilmente incoerente, secondo cui esisterebbe una dimensione fenomenica inconscia. Parole chiave: Credenza; Coscienza; Inconscio; Contenuto intenzionale; Giudizio. (shrink)

There has recently been emphasis put on providing two-factor accounts of monothematic delusions. Such accounts would explain (1) whether a delusional hypothesis (e.g. someone else is inserting thoughts into my mind) can be understood as a prima facie reasonable response to an experience and (2) why such a delusional hypothesis is believed and maintained given its implausibility and evidence against it. I argue that if we are to avoid obfuscating the cognitive mechanisms involved in monothematic delusion formation we should split (...) the first factor (1 above) into two factors: how abnormal experience can give rise to a delusional ‘proto-hypothesis’ and how a ‘proto-hypothesis’ in consort with normal experiences and background information, can be developed into a delusional hypothesis. In particular I will argue that a schizophrenic is faced with the unusual requirement of having to identify an introspectively accessible thought as one's own, and that this requirement of identification is the central experiential abnormality of thought insertion, auditory verbal hallucination, and alien control (i.e. passivity symptoms). Additionally, I will consider non-experiential factors which are required for the formation of a delusional hypothesis. (shrink)

Article copyright 2002. We provide a battery of examples of delusions against which theoretical accounts can be tested. Then we identify neuropsychological anomalies that could produce the unusual experiences that may lead, in turn, to the delusions in our battery. However, we argue against Maher's view that delusions are false beliefs that arise as normal responses to anomalous experiences. We propose, instead, that a second factor is required to account for the transition from unusual experience to delusional belief. The second (...) factor in the etiology of delusions can be described superficially as a loss of the ability to reject a candidate for belief on the grounds of its implausibility and its inconsistency with everything else that the patient knows, but we point out some problems that confront any attempt to say more about the nature of this second factor.

What is given to us in conscious experience? The Given is an attempt to answer this question and in this way contribute to a general theory of mental content. The content of conscious experience is understood to be absolutely everything that is given to one, experientially, in the having of an experience. Michelle Montague focuses on the analysis of conscious perception, conscious emotion, and conscious thought, and deploys three fundamental notions in addition to the fundamental notion of content: the notions (...) of intentionality, phenomenology, and consciousness. She argues that all experience essentially involves all four things, and that the key to an adequate general theory of what is given in experience lies in giving a correct specification of the nature of these four things and the relations between them.

Breaking new ground in the debate about the relation of mind and body, David Armstrong's classic text - first published in 1968 - remains the most compelling and comprehensive statement of the view that the mind is material or physical. In the preface to this new edition, the author reflects on the book's impact and considers it in the light of subsequent developments. He also provides a bibliography of all the key writings to have appeared in the materialist debate.

Phenomenology is about subjective aspects of the mind, such as the conscious states associated with vision and touch, and the conscious states associated with emotions and moods, such as feelings of elation or sadness. These states have a distinctive first-person ‘feel’ to them, called their phenomenal character. In this respect they are often taken to be radically different from mental states and processes associated with thought. This is the first book to fully question this orthodoxy and explore the prospects of (...) cognitive phenomenology, applying phenomenology to the study of thought and cognition. Does cognition have its own phenomenal character? Can introspection tell us either way? If consciousness flows in an unbroken ‘stream’ as William James argued, how might a punctuated sequence of thoughts fit into it? Elijah Chudnoff begins with a clarification of the nature of the debate about cognitive phenomenology and the network of concepts and theses that are involved in it. He then examines the following topics: • Introspection and knowledge of our own thoughts • Phenomenal contrast arguments • The value of consciousness • The temporal structure of experience • The holistic character of experience and the interdependence of sensory and cognitive states • The relationship between phenomenal character and mental representation -/- Including chapter summaries, annotated further reading, and a glossary, this book is essential reading for anyone seeking a clear and informative introduction to and assessment of cognitive phenomenology, whether philosophy student or advanced researcher. It will also be valuable reading for those in related subjects such as philosophy of mind, philosophy of psychology and epistemology. (shrink)

This paper considers the connection between automaticity, control and agency. Indeed, recent philosophical and psychological works play up the incompatibility of automaticity and agency. Specifically, there is a threat of automaticity, for automaticity eliminates agency. Such conclusions stem from a tension between two thoughts: that automaticity pervades agency and yet automaticity rules out control. I provide an analysis of the notions of automaticity and control that maintains a simple connection: automaticity entails the absence of control. An appropriate analysis, however, shows (...) that actions are forms of control and pervasively automatic even if automaticity implies the absence of control. Consequences are drawn for the theory of mental agency and the psychological concepts of automaticity and control. (shrink)

Over the last 20 years the comparator model for delusions of control has received considerable support in terms of empirical studies. However, the original version clearly needs to be replaced by a model with a much greater degree of sophistication and specificity. Future developments are likely to involve the specification of the role of dopamine in the model and a generalisation of its explanatory power to the whole range of positive symptoms. However, we will still need to explain why symptoms (...) can be so variable and we still do not understand the origin of the most mysterious symptom of all: thought insertion. (shrink)

In the past dozen years a number of theoretical models of schizophrenic symptoms have been proposed, often inspired by advances in the cognitive sciences, and especially cognitive neuroscience. Perhaps the most widely cited and influential of these is the neurocognitive model proposed by Christopher Frith (1992). Frith's influence reaches into psychiatry, neuroscience, and even philosophy. The philosopher John Campbell (1999a), for example, has called Frith's model the most parsimonious explanation of how self-ascriptions of thoughts are subject to errors of identification. (...) "On reflection, it also seems that this is not just one possible theory; it is the simplest theory which has any prospect of explaining the sense of agency, and we ought to work from it, introducing complications only as necessary" (1999a, p. 612). Not everyone agrees. In their recent analysis of alien voices and inserted thoughts in schizophrenia, Stephens and Graham (2000) offer a critique of Frith. Their criticism, however, although serious, is neither deep nor extensive. They outline three points. First, Frith fails to provide an adequate account of why a subject who experiences thought insertion would misattribute that thought to some other agent. Second, Frith does not clarify the distinction between thought insertion and thought influence. And third, Frith fails to explain how a subject can claim both that he is thinking the thought and that the thought is someone else's thought (Stephens and Graham.. (shrink)

A number of philosophers endorse, without argument, the view that there’s something it’s like consciously to think that p, which is distinct from what it’s like consciously to think that q. This thesis, if true, would have important consequences for philosophy of mind and cognitive science. In this paper I offer an argument for it, and attempt to induce examples of it in the reader. The argument claims it would be impossible introspectively to distinguish conscious thoughts with respect to their (...) content if there weren’t something it’s like to think them. This argument is defended against several objections. Then I use what I call “minimal pair” experiences—sentences read without and with understanding—to induce in the reader an experience of the kind I claim exists. Further objections are considered and rebutted. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 9.1 (2002) 35-39 [Access article in PDF] The Ownership of Thoughts John Campbell Keywords: schizophrenia, thought insertion, immunity to error through misidentification. SYDNEY SHOEMAKER FORMULATED a basic point about first-person, present-tense ascriptions of psychological states when he declared that they are, in general, immune to error through misidentification (Shoemaker 1984). Assuming Shoemaker's point to be correct, the puzzle it raises is this: how are we (...) to explain this datum? Why should it be that first-person, present-tense ascriptions of psychological states are immune to error through misidentification? One type of explanation is in terms of the meaning of the first person: that "I" just stands for whoever is the owner of these (demonstrated) psychological states (including any states being self-ascribed). I argued against this account of the first person in a number of places, and in favor of an alternative explanation of Shoemaker's datum. On the alternative explanation, the reason for the immunity is provided by an account of the ownership of psychological states, on which what makes a psychological state mine is the possibility of self-ascription of it by me (Campbell 1986, 1999a). Suppose we call this the Introspectionist explanation of the immunity to error through misidentification of present-tense self-ascriptions of psychological states. I do think, though, that the simple Introspectionist account is too simple an account of Shoemaker's datum (Campbell 1999a, 1999b). The reason is that there is a certain complexity in our notion of the ownership of a token thought. We cannot give a full account of our ordinary notion of the ownership of a thought simply in terms of the person who is capable of introspective knowledge of the thought. The reason is that there is another dimension to our ordinary notion of the ownership of a thought. We also think of the possessor of a thought as being the person who generated that very thought; we think of the owner of the thought as being the person who brought that particular token thought into existence, the person who formed it. Of course, that token thought may be a copying of someone else's idea; that other person may have influenced my formation of that particular thought. But the point remains that I play a special role in the production of my thoughts.Suppose we have a document bearing a signature and we ask, "Whose signature is that?" In this case we are asking about the authorship of the signature; we are asking who made those particular marks on that bit of paper. Of course, someone else can copy my signature, trying to make it look as if what they write was written by me. But for a particular piece of writing to be an authentic signature of mine, the thing has to be generated by me personally. I think it is helpful to bear in mind this aspect of the notion of the ownership of a signature, when we consider a certain complexity in the notion of the ownership of a thought—I mean, an occurrent, episodic [End Page 35] thought. There are, I am saying, two strands in the ordinary notion of the ownership of a thought, which we do not ordinarily have any reason to separate. First, there is the notion of the person who generated that particular thought, which we might think of on the model of the person who inscribed a particular signature. Of course, in generating a particular token thought, you may be subject to all sorts of influences. Perhaps your thought is derivative, largely shaped by others. Perhaps your thoughts are sometimes simply echoes of the things other people have said. Nonetheless, when we consider how your individual token thoughts are being brought about, you play a proximal role in their formation that no one else does. To give an analogy, suppose that I am taking notes at your dictation. Then there is a sense in which the contents of my notes are entirely determined by you. But there is also a sense in which the token sentences are being generated by... (shrink)

Two kinds of epistemological sceptical paradox are reviewed and a shared assumption, that warrant to accept a proposition has to be the same thing as having evidence for its truth, is noted. 'Entitlement', as used here, denotes a kind of rational warrant that counterexemplifies that identification. The paper pursues the thought that there are various kinds of entitlement and explores the possibility that the sceptical paradoxes might receive a uniform solution if entitlement can be made to reach sufficiently far. Three (...) kinds of entitlement are characterized and given prima facie support, and a fourth is canvassed. Certain foreseeable limitations of the suggested antisceptical strategy are noted. The discussion is grounded, overall, in a conception of the sceptical paradoxes not as directly challenging our having any warrant for large classes of our beliefs but as crises of intellectual conscience for one who wants to claim that we do.

Reviews evidence which suggests that there may be little or no direct introspective access to higher order cognitive processes. Ss are sometimes unaware of the existence of a stimulus that importantly influenced a response, unaware of the existence of the response, and unaware that the stimulus has affected the response. It is proposed that when people attempt to report on their cognitive processes, that is, on the processes mediating the effects of a stimulus on a response, they do not do (...) so on the basis of any true introspection. Instead, their reports are based on a priori, implicit causal theories, or judgments about the extent to which a particular stimulus is a plausible cause of a given response. This suggests that though people may not be able to observe directly their cognitive processes, they will sometimes be able to report accurately about them. Accurate reports will occur when influential stimuli are salient and are plausible causes of the responses they produce, and will not occur when stimuli are not salient or are not plausible causes.

In this paper, I investigate in detail one theoretical approach to the symptom of thought insertion. This approach suggests that patients are lead to disown certain thoughts they are subjected to because they lack a sense of active participation in the occurrence of those thoughts. I examine one reading of this claim, according to which the patients’ anomalous experiences arise from a breakdown of cognitive mechanisms tracking the production of occurrent thoughts, before sketching an alternative reading, according to which their (...) experiences have to be explained in terms of a withdrawal, on the part of the patients themselves, from certain forms of active engagement in reasoning. I conclude with a discussion of the relationship between this view and the idea that patients’ reports of thought insertion reflect a situation in which the boundaries between the self and the world have become uncertain.

Ordinarily, if you say something like “I see a comet,” you might make a mistake about whether it is a comet that you see, but you could not be right about whether it is a comet but wrong about who is seeing it. There cannot be an “error of identification” in this case. In making a judgement like, “I see a comet,” there are not two steps, finding out who is seeing the thing and finding out what it is that (...) is being seen, so that you could go wrong at either step. The only place to go wrong is in your description of what is being seen. We usually take it that the same point applies to present-tense ascriptions to oneself of psychological states in general. You can get it wrong about which psychological state you are in, but you cannot get it right about the psychological state but wrong about whose psychological state it is. In contrast, in a room full of people, I might hear a noise and conclude, “Bill sneezed,” and in this case I could be wrong either about who it was that sneezed or about whether it was a sneeze, rather than say a death-rattle.

This is a book about how we see: the environment around us (its surfaces, their layout, and their colors and textures); where we are in the environment; whether or not we are moving and, if we are, where we are going; what things are good for; how to do things (to thread a needle or drive an automobile); or why things look as they do.The basic assumption is that vision depends on the eye which is connected to the brain. The (...) author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another. That is natural vision—and what this book is about. (shrink)

John Campbell (1999) has recently maintained that the phenomenon of thought insertion as it is manifested in schizophrenic patients should be described as a case in which the subject is introspectively aware of a certain thought and yet she is wrong in identifying whose thought it is. Hence, according to Campbell, the phenomenon of thought insertion might be taken as a counterexample to the view that introspection-based mental selfascriptions are logically immune to error through misidentification (IEM, hereafter). Thus, if Campbell (...) is right, it would not be true that when the subject makes a mental self-ascription on the basis of introspective awareness of a given mental state, there is no possible world in which she could be wrong as to whether it is really she who has that mental state. Notice the interesting interdisciplinary implications of Campbell’s project: on the one hand, a fairly precise notion elaborated in philosophy such as IEM (and the related notion of error through misidentification, EM hereafter) is used to describe a characteristic symptom of schizophrenia.1 On the other hand, such a phenomenon, described in the way proposed, is taken to be a possible counterexample to a sort of “philosophical dogma” such as IEM of introspection-based non-inferential mental self-ascriptions. In the first section of the paper I will point out the characteristic features of EM and explain logical immunity to error through misidentification of introspection-based mental self-ascriptions; in the second section I will consider the case of thought insertion in more detail and show why, after all, it is not a counterexample to the view that introspectionbased mental self-ascriptions are logically IEM. Finally, I will offer a re-description of the phenomenon of thought insertion. (shrink)

I examine the central theoretical construct of ecological psychology, the concept of an affordance. In the first part of the paper, I illustrate the role affordances play in Gibson's theory of perception. In the second part, I argue that affordances are to be understood as dispositional properties, and explain what I take to be their characteristic background circumstances, triggering circumstances and manifestations. The main purpose of my analysis is to give affordances a theoretical identity enriched by Gibson's visionary insight, but (...) independent of the most controversial claims of the Gibsonian movement.

Where does the mind stop and the rest of the world begin? The question invites two standard replies. Some accept the demarcations of skin and skull, and say that what is outside the body is outside the mind. Others are impressed by arguments suggesting that the meaning of our words "just ain't in the head", and hold that this externalism about meaning carries over into an externalism about mind. We propose to pursue a third position. We advocate a very different (...) sort of externalism: an _active externalism_, based on the active role of the environment in driving cognitive processes.

Consciousness is a mongrel concept: there are a number of very different "consciousnesses." Phenomenal consciousness is experience; the phenomenally conscious aspect of a state is what it is like to be in that state. The mark of access-consciousness, by contrast, is availability for use in reasoning and rationally guiding speech and action. These concepts are often partly or totally conflated, with bad results. This target article uses as an example a form of reasoning about a function of "consciousness" based on (...) the phenomenon of blindsight. Some information about stimuli in the blind field is represented in the brains of blindsight patients, as shown by their correct "guesses," but they cannot harness this information in the service of action, and this is said to show that a function of phenomenal consciousness is somehow to enable information represented in the brain to guide action. But stimuli in the blind field are BOTH access-unconscious and phenomenally unconscious. The fallacy is: an obvious function of the machinery of access-consciousness is illicitly transferred to phenomenal consciousness. (shrink)

An examination of verbal hallucinations and thought insertion as examples of "alienated self-consciousness.".

In this paper we focus on a kind of perceptual states that we call perceptual motivations, that is, perceptual experiences that plausibly motivate us to act, such as itching, perceptual salience and pain. Itching seems to motivate you to scratch, perceiving a stimulus as salient seems to motivate you to attend to it and feeling a pain in your hand seems to motivate actions such as withdrawing from the painful stimulus. Five main accounts of perceptual motivation are available: Descriptive, Conative, (...) Imperativist, Reflexive and Dual Content views. Some of these have been developed in detail and others are natural extensions of existing views. However, we argue that none provides a satisfactory account of the target perceptual states. Driven by the failings of each account, we identify three conditions that any satisfactory theory of perceptual motivation must meet: Direct Motivational Force, Non-Obligatory Force and Intention-Independent Influence. Then we offer an account that attempts to fulfil these conditions: the Affordance Model. This model of perceptual motivation is premised on the claim that each of the target states involves the perception of a specific affordance for action and the triggering of Automatic Motor Initiations (AMIs). We suggest that AMIs can explain the motivational force of these perceptual states. (shrink)

Mental acts are conspicuously absent from philosophical debates over the nature of action. A typical protagonist of a typical scenario is far more likely to raise her arm or open the window than she is to perform a calculation in her head or talk to herself silently. One possible explanation for this omission is that the standard ‘causalist’ account of action, on which acts are analyzed in terms of mental states causing bodily movements, faces difficulties in accommodating some paradigmatic cases (...) of mental action – or so I argue. After drawing out these objections to causalism, I outline a more promising approach. Building on previous work, I show how the approach I favour, on which the attempt to analyze action is dispensed with, provides a unified account of both mental and physical action. (shrink)

Many bodily sensations are connected quite closely with specific actions: itches with scratching, for example, and hunger with eating. Indeed, these connections have the feel of conceptual connections. With the exception of D. M. Armstrong, philosophers have largely neglected this aspect of bodily sensations. In this paper, I propose a theory of bodily sensations that explains these connections. The theory ascribes intentional content to bodily sensations but not, strictly speaking, representational content. Rather, the content of these sensations is an imperative: (...) in the case of itches, 'Scratch!' The view avoids non-intentional qualia and hence accords with what could be called, generalizing Lycan slightly, the 'hegemony of intentionality'. (shrink)

Philosophers are interested in the phenomenon of thought insertion because it challenges the common assumption that one can ascribe to oneself the thoughts that one can access first-personally. In the standard philosophical analysis of thought insertion, the subject owns the ‘inserted’ thought but lacks a sense of agency towards it. In this paper we want to provide an alternative analysis of the condition, according to which subjects typically lack both ownership and authorship of the ‘inserted’ thoughts. We argue that by (...) appealing to a failure of ownership and authorship we can describe more accurately the phenomenology of thought insertion, and distinguish it from that of non-delusional beliefs that have not been deliberated about, and of other delusions of passivity. We can also start developing a more psychologically realistic account of the relation between intentionality, rationality and self knowledge in normal and abnormal cognition. (shrink)

G. E. Moore was one of the most interesting and influential philosophers of the first half of the twentieth century. This selection of his writings makes the best of his work once again available, and also includes previously unpublished writings. Moore's first published writings, represented in this collection by his papers "The Nature of Judgment" and "The Refutation of Idealism," contributed decisively to the break with idealism which led to the development of analytic philosophy. Moore went on to develop his (...) own style, which combined a defense of the common sense view of the world with a controversial analysis of the content of this view. Also included is Moore's famous "Proof of an External World," which marked a return late in his career to the critique of idealism. Other papers address perception and important issues in logical theory. The collection ends with three new pieces which illustrate Moore's relationship with Wittgenstein. In these pieces Moore discusses his "paradox" whichso fascinated Wittgenstein; the nature of our knowledge of our own sensations; and Malcolm's views about doubt and knowledge which were themselves inspired by Wittgenstein.

INTRODUCTION: In accounts of the two-factor theory of delusional belief, the second factor in this theory has been referred to only in the most general terms, as a failure in the processes of hypothesis evaluation, with no attempt to characterise those processes in any detail. Coltheart and Davies attempted such a characterisation, proposing a detailed eight-step model of how unexpected observations lead to new beliefs based on the concept of abductive inference as introduced by Charles Sanders Peirce. METHODS: In this (...) paper, we apply that model to the explanation of various forms of delusional belief. RESULTS: We provide evidence that in cases of delusion there is a specific failure of the seventh step in our model: the step at which predictions from hypotheses are considered in the light of relevant evidence. CONCLUSIONS: In the two-factor theory of delusional belief, the second factor consists of a failure to reject hypotheses in the face of disconfirmatory evidence. (shrink)

Aspects of Psychologism is a penetrating look into fundamental philosophical questions of consciousness, perception, and the experience we have of our mental lives. Psychologism, in Tim Crane’s formulation, presents the mind as a single subject-matter to be investigated not only empirically and conceptually but also phenomenologically: through the systematic examination of consciousness and thought from the subject’s point of view.

We argue that thought insertion primarily involves a disruption of the sense of ownership for thoughts and that the lack of a sense of agency is but a consequence of this disruption. We defend the hypothesis that this disruption of the sense of ownership stems from a fail- ure in the online integration of the contextual information related to a thought, in partic- ular contextual information concerning the different causal factors that may be implicated in their production. Loss of unity (...) of consciousness, manifested by incoherent subjective experiences is a general phenomenal characteristic of schizophrenia. This loss of coherence has been hypothesized to reflect a generalized deficit of contextual information integration not conveyed by, but related to, a target event. This deficit is manifested across many cog- nitive domains. We argue that it is also manifested in the process of thinking itself, result- ing in causally decontextualized thoughts that are experienced as inserted thoughts. (shrink)

Several philosophers have recently advanced the claim that the content of mental states has its own non-imagistic phenomenology. I show that if defenders of cognitive phenomenology are to account for the conscious experience of thoughts, they must actually commit themselves to two different kinds of cognitive phenomenology, which I refer to as ‘general’ and ‘specific.’ Once this distinction is made, we can see how arguments from experience for cognitive phenomenology depend on an ambiguity in ‘what it is like’ talk for (...) their success. Disambiguating this kind of talk into talk of either general or specific phenomenology shows that these arguments are either valid – but assume what they are trying to prove – or are not valid.
