In The Rules of Insanity, Carl Elliott draws on philosophy and psychiatry to develop a conceptual framework for judging the moral responsibility of mentally ill offenders. Arguing that there is little useful that can be said about the responsibility of mentally ill offenders in general, Elliott looks at specific mental illnesses in detail; among them schizophrenia, manic-depressive disorders, psychosexual disorders such as exhibitionism and voyeurism, personality disorders, and impulse control disorders such as kleptomania and pyromania. He takes a (...) particularly hard look at the psychopath or sociopath, who many have argued is incapable of understanding morality. Making extensive use of psychiatric case histories, Elliott explores the various ways in which mental illness can affect a person's intentions and thus excuse him or her from moral responsibility.

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)

BackgroundSexual boundary violations in healthcare are harmful and exploitative sexual transgressions in the professional–client relationship. Persons with mental health issues or intellectual disabilities, especially those living in residential settings, are especially vulnerable to SBV because they often receive long-term intimate care. Promoting good sexual health and preventing SBV in these care contexts is a moral and practical challenge for healthcare organizations.MethodsWe carried out a qualitative interview study with 16 Dutch policy advisors, regulators, healthcare professionals and other relevant experts to (...) explore their perspectives on preventing SBV in mental health and disability care organizations. We used inductive thematic analysis to interpret our data.ResultsWe found three main themes on how healthcare organizations can prevent SBV in mental health and disability care: setting rules and regulations, engaging in dialogue about sexuality, and addressing systemic and organizational dimensions.ConclusionOur findings suggest that preventing SBV in mental health and disability care organizations necessitates setting suitable rules and regulations and facilitating dialogue about positive aspects of sexuality and intimacy, as well as about boundaries, and inappropriate behaviors or feelings. Combining both further requires organizational policies and practices that promote transparency and reflection, and focus on creating a safe environment. Our findings will help prevent SBV and promote sexual health in mental health and disability care organizations. (shrink)

Researchers currently working on relational reasoning typically argue that mental model theory (MMT) is a better account than the inference rule approach (IRA). They predict and observe that determinate (or one-model) problems are easier than indeterminate (or two-model) problems, whereas according to them, IRA should lead to the opposite prediction. However, the predictions attributed to IRA are based on a mistaken argument. The IRA is generally presented in such a way that inference rules only deal with determinate relations (...) and not with indeterminate ones. However, (a) there is no reason to presuppose that a rule-based procedure could not deal with indeterminate relations, and (b) applying a rule-based procedure to indeterminate relations should result in greater difficulty. Hence, none of the recent articles devoted to relational reasoning currently presents a conclusive case for discarding IRA by using the well-known determinate vs indeterminate problems comparison.

Wittgenstein’s later works are full of questions about the timing and duration of mental phenomena. These questions are often awkward ones, and Wittgenstein seems to take their awkwardness to be philosophically revealing, but if we ask what it is that these questions reveal then different interpretations are possible. This paper suggests that there are at least six different ways in which the timing of mental phenomena can be awkward. By identifying these we can give sense to some of (...) Wittgenstein’s more cryptic remarks, and doing this enables us to clarify some obscure elements in his picture of the mind, including the distinction between sensations and feelings, and his account of the rational status of those processes out of which rule-following is built.

Mental time travel is defined as projecting the self into the past and the future. Despite growing evidence of the similarities of remembering past and imagining future events, dominant theories conceive of these as distinct capacities. I propose that memory and imagination are fundamentally the same process – constructive episodic simulation – and demonstrate that the ‘simulation system’ meets the three criteria of a neurocognitive system. Irrespective of whether one is remembering or imagining, the simulation system: acts on the (...) same information, drawing on elements of experience ranging from fine-grained perceptual details to coarser-grained conceptual information and schemas about the world; is governed by the same rules of operation, including associative processes that facilitate construction of a schematic scaffold, the event representation itself, and the dynamic interplay between the two ; and is subserved by the same brain system. I also propose that by forming associations between schemas, the simulation system constructs multi-dimensional cognitive spaces, within which any given simulation is mapped by the hippocampus. Finally, I suggest that simulation is a general capacity that underpins other domains of cognition, such as the perception of ongoing experience. This proposal has some important implications for the construct of ‘MTT’, suggesting that ‘time’ and ‘travel’ may not be defining, or even essential, features. Rather, it is the ‘mental’ rendering of experience that is the most fundamental function of this domain-general simulation system enabling humans to re-experience the past, pre-experience the future, and also comprehend the complexities of the present.

Mental models theorists have proposed that reasoners tend to focus on what is explicit in their mental models, and that certain debiasing procedures can induce them to direct their attention to other relevant information. For instance, Green and Larking 1995; also Green, 1995a facilitated performance on the Wason selection task by inducing participants to consider counterexamples to the conditional rule. However, these authors acknowledged that one aspect of their data might require some modification to the mental models (...) theory. This research is discussed here, and it is suggested that the results may be better accommodated by mental inference rules theory than by mental models theory. (shrink)

The reflections on music are crucial in the philosophy of language and the mind of the second Wittgenstein. These reflections go around the comparisons Wittgenstein did between meaning and understanding language, and meaning and understanding music. Musical passages show a language as independent from reality, i.e. objects, events or mental states, centered instead in intonations, conclusions, parenthesis, confirmations, questions and answers, a phenomenon enough studied in musicology. Two interpretations on the signification of musical meaning are analyzed: Ahonen’s formalist view (...) [2005], based in the following of rules, and Scruton’s expressive view [2004], based on the comparison between the intuitive recognition of a mental state “hidden” behind the facial expressions. As a conclusion we arrive to a mixed argument: Either of the alternatives whether annulling the other, are possibly telling about Wittgenstein’s conception but do not elucidate the problem itself.

The rule-following debate, in its concern with the metaphysics and epistemology of linguistic meaning and mental content, goes to the heart of the most fundamental questions of contemporary philosophy of mind and language. This volume gathers together the most important contributions to the topic, including papers by Simon Blackburn, Paul Boghossian, Graeme Forbes, Warren Goldfarb, Paul Horwich, John McDowell, Colin McGinn, Ruth Millikan, Philip Pettit, George Wilson, and José Zalabardo. This debate has centred on Saul Kripke's reading of the (...) rule-following sections in Wittgenstein and his consequent posing of a "sceptical paradox" that threatens our every day notions of linguistic meaning and mental content. These essays are attempts to respond to this challenge and represent some of the most important work in contemporary theory of meaning. They examine the notion of meaning; whether it is possible to find a suitable meaning-constituting fact from our previous behaviour or mental histories; objections to, and defenses of, dispositional accounts of meaning; the plausibility of non-factualism about meaning; our attempts to develop non-reductionist accounts of meaning; and the sources of the normativity which attaches to meaning, such as the linguistic practice of the community or the dispositions of the individual. With an introductory essay and a comprehensive guide to further reading the book is an excellent resource for courses in philosophy of mind, philosophy of language, Wittgenstein, and metaphysics, as well as for all philosophers, linguists, and cognitive scientists with interests in these areas. Contributors include Simon Blackburn, Paul Boghossian, Graeme Forbes, Warren Goldfarb, Paul Horwich, John McDowell, Colin McGinn, Alexander Miller, Ruth Garrett Millikan, Philip Pettit, George. M. Wilson, Crispin Wright, and José L. Zalabardo. (shrink)

In COVID’s immediate wake, the 2020 death toll from a different enemy of the public’s health — gun violence — ticked up by 15 percent in the United States from the previous year. Meanwhile, the U.S. Supreme Court issued an opinion in Caniglia v. Strom that will allow people who have recently threatened suicide — with a gun — to keep unsecured guns in their home unless police take time to obtain a search warrant to remove them.

The concept of a rule that primarily interests Wittgenstein is one that is central to our understanding of 'what is possible before all new discoveries and inventions'. Wittgenstein's investigations of the concept of a rule run 'criss‐cross in every direction'. As Wittgenstein points out, 'any interpretation still hangs in the air along with what it interprets, and cannot give it any support'. Like our inner mental picture of a cube, what we think of as an interpretation of a rule (...) doesn't by itself predetermine the steps that accord with the rule it supposedly interprets. In his great work, Philosophical Investigations, Wittgenstein aims both to uncover the sources of these difficulties and to show his readers how to overcome them. In particular, he aims to expose the emptiness of tempting philosophical explanations of the notion of grounds for correct continuation of a rule. (shrink)

The book from which these sections are excerpted is concerned with the prospects for assimilating the study of human intelligence and its products to the natural sciences through the investigation of cognitive structures, understood as systems of rules and representations that can be regarded as “mental organs.” These mental structui′es serve as the vehicles for the exercise of various capacities. They develop in the mind on the basis of an innate endowment that permits the growth of rich (...) and highly articulated structures along an intrinsically determined course under the triggering and partially shaping effect of experience, which fixes parameters in an intricate system of predetermined form. It is argued that the mind is modular in character, with a diversity of cognitive structures, each with its specific properties arid principles. Knowledge of language, of the behavior of objects, and much else crucially involves these mental structures, and is thus not characterizable in terms of capacities, dispositions, or practical abilities, nor is it necessarily grounded in experience in the standard sense of this term.Various types of knowledge and modes of knowledge acquisition are discussed in these terms. Some of the properties of the language faculty are investigated. The basic cognitive relation is “knowing a grammar”; knowledge of language is derivative and, correspondingly, raises further problems. Language as commonly understood is not a unitary phenomenon but involves a number of interacting systems: the “computational” system of grammar, which provides the representations of sound and meaning that permit a rich range of expressive potential, is distinct from a conceptual system with its own properties; knowledge of language must be distinguished from knowledge of how to use a language; and the various systems that enter into the knowledge and use of language must be further analyzed into their specific subcomponents.

The target article focuses exclusively on System 2 and on reasoning rationality: the ability to reach valid conclusions from available information, as in the Wason task. The decision-theoretic concept of coherence rationality requires beliefs to be consistent, even when they are assessed one at a time. Judgment heuristics belong to System 1, and help explain the incoherence of intuitive beliefs.

Foundational theories of mental content seek to identify the conditions under which a mental representation expresses, in the mind of a particular thinker, a particular content. Normativists endorse the following general sort of foundational theory of mental content: A mental representation r expresses concept C for agent S just in case S ought to use r in conformity with some particular pattern of use associated with C. In response to Normativist theories of content, Kathrin Glüer-Pagin and (...) Åsa Wikforss propose a dilemma, alleging that Normativism either entails a vicious regress or falls prey to a charge of idleness. In this paper, I respond to this argument. I argue that Normativism can avoid the commitments that generate the regress and does not propose the sort of explanation required to charge that its explanation has been shown to be problematically idle. The regress-generating commitment to be avoided is, roughly, that tokened, contentful mental states are the product of rule-following. The explanatory task Normativists should disavow is that of explaining how it is that beliefs and other contentful mental states are produced. I argue that Normativism, properly understood as a theory of content, does not provide this kind of psychological explanation, and therefore does not entail that such explanations are to be given in terms of rule-following. If this is correct, Normativism is not the proper target of the dilemma offered by Glüer-Pagin and Wikforss. Understanding why one might construe Normativism in the way Glüer-Pagin and Wikforss must, and how, properly understood, it avoids their dilemma, can help us to appreciate the attractiveness of a genuinely normative theory of content and the importance of paying careful attention to the sort of normativity involved in norm-based theories of content.

Mental content normativists hold that the mind’s conceptual contents are essentially normative. Many hold the view because they think that facts of the form “subject S possesses concept c” imply that S is enjoined by rules concerning the application of c in theoretical judgments. Some opponents independently raise an intuitive objection: even if there are such rules, S’s possession of the concept is not the source of the enjoinment. Hence, these rules do not support mental (...) content normativism. Call this the “Source Objection.” This paper refutes the Source Objection, outlining a key strand of the relationship between judgments and their contents in the process. Theoretical judgment and mental conceptual content are equally the source of enjoinment; norms for judging with contents do not derive from one at the expense of the other. (shrink)

Normativists about belief hold that belief formation is essentially rule- or norm-guided. On this view, certain norms are constitutive of or essential to belief in such a way that no mental state not guided by those norms counts as a belief, properly construed. In recent influential work, Kathrin Glüer and Åsa Wikforss develop novel arguments against normativism. According to their regress of motivations argument, not all belief formation can be rule- or norm-guided, on pain of a vicious infinite regress. (...) I argue that the regress of motivations argument is unsuccessful: an appeal to the notion of blind rule-following, drawn from a plausible interpretation of Ludwig Wittgenstein’s remarks on rule-following, stops the regress of motivations in its tracks.

The view that psychological episodes have a physical nature (physicalism) and the view that they have a mental nature (Cartesian dualism) can be distinguished from the view that they have a purely normative nature. I explore some strands of a distinct, fourth view: psychological episodes are what they are because of the actual and possible relations of defeasible justification in which they stand; defeasible justification is an internal relation; it is not at bottom a normative matter; rule-following presupposes such (...) internal relations; to follow a rule is not to break it.

Mental explanations of behaviour are physical explanations of a special kind. Mental events are physical events. Mental explanations of physical behaviour are not mysterious, they designate events with physical causal powers. Mentalistic terms differ from physicalistic ones in the way they specify events: the former cite extrinsic properties, the latter intrinsic properties. The nature of explanation in general is discussed, and a naturalistic view of intentionality is proposed. The author shows why epistemological considerations rule out the elimination (...) of "mentalistic talk" from explanations of behaviour. (shrink)

Ichikawa and Jarvis offer a new rationalist theory of mental content and defend a traditional epistemology of philosophy. They argue that philosophical inquiry is continuous with non-philosophical inquiry, and can be genuinely a priori, and that intuitions do not play an important role in mental content or the a priori.

The Mental Capacity Act received Royal Assent on 7 April 2005, and it will be implemented in 2007. The Act defines when someone lacks capacity and it supports people with limited decision-making ability to make as many decisions as possible for themselves. The Act lays down rules for substitute decision making. Someone taking decisions on behalf of the person lacking capacity must act in the best interests of the person concerned and choose the options least restrictive of his (...) or her rights and freedoms. Decision making will be allowed without any formal procedure unless specific provisions apply, such as a written advance decision, lasting powers of attorney or a decision by the court of protection.

Johnson-Laird and Byrne present a theory of conditional inference based upon the manipulation of mental models. In the present paper, the theory is critically examined with regard to its ability to account for psychological data, principally with respect to the rate at which people draw the four basic inferences of modus ponens, denial of the antecedent, affirmation of the consequent and modus tollens. It is argued first that the theory is unclear in its definition and in particular with regard (...) to predictions of problem difficulty. Clarification and specification of principles are consequently provided here. Next, it is argued that there are a number of phenomena in the conditional reasoning literature for which the theory cannot account in its present form. Specifically, the relatively frequency of DA and AC inferences on affirmative conditionals is not as predicted by the theory, differences occur between inferences on if then and only if rules beyond the capacity of the theory to explain and there is no account of the “negative conclusion bias” observed when negated components are introduced into the rules. A number of revisions to the mental model theory of conditional reasoning are proposed in order to account for these findings. (shrink)

Celano’s notion of a “pre-convention” is grounded in the opposition between two allegedly different kinds of normative behaviour: observing a “rule” and conforming to a “norm”. This opposition plays a central role in Celano’s paper, and marks a crucial point in his intellectual trajectory. Nevertheless, it remains largely implicit. In this paper, I try to make it fully explicit, giving a more precise characterisation of both kinds of normative behaviour. I also focus on the importance of distinguishing between them, express (...) some conjectures regarding Celano’s future research, and propose a criticism. (shrink)

Difficulty of distinguishing rules and similarity in categorization comes from reliance on relatively simple manipulation-response designs and a style of modeling with abstract parameters, rather than assessment of intervening and controlling mental states. This commentary proposes a strategy in which rules and similarity would be distinguished by their different roles in a theory interrelating reportable conscious contents in deliberative categorization.

Davidson's principle of the anomalousness of the mental was instrumental in discrediting once-popular versions of mind-brain reductionism. In this essay I argue that a novel account of intertheoretic reduction, which does not require the sort of cross-theoretic bridge laws that Davidson's principle rules out, allows a version of mind-brain reductionism which is immune from Davidson's challenge. In the final section, I address a second worry about reductionism, also based on Davidson's principle, that survives this response. I argue that (...) new reductionists should revise some significant details of the program, particularly the conception of theories, to circumvent this more potent Davidson-inspired worry. (shrink)

According to some views, natural language suffers from underdeterminacy, but thought doesn’t. According to the underdeterminacy claim, sentence types underdetermine the truth-conditions of sentence tokens. In particular, the semantics of a predicate type seems to underdetermine the satisfaction conditions of its tokens. By contrast, mental representation-types are supposed to determine the truth-conditions of its tokens. In this paper I critically examine these mixed views. First, I argue that the arguments supporting the indispensability of including in one’s theory mental (...) representations that are free of the underdeterminacy exhibited by natural language are not sound. As a result, the possibility that mental representation-types are as underdetermined as natural language sentence-types has not been ruled out. Second, I argue that Carston’s ad hoc concept-types are as underdetermined as word-types. I finish by arguing that mental representations are also underdetermined in a second sense—mental representation-tokens only determine a partial function from possible worlds to truth-values.

This paper focuses some aspects of a debate which took place between Donald Davidson and Jaegwon Kim, about the problem of causal efficacy of mental properties in the physical world. The most famous expression of davidsoniannon reductive physicalism, the argument of Anomalous Monism, was criticized by Kim, because it tries to harmonize two allegations that can´t coexist in a physicalist thesis, and have to be considered as incompatible from a physicalistpoint of view. The first of these allegations is theAnomaly (...) of the Mental, whichdefines the mental as autonomous from the system of laws that rule physical phenomena. The second allegation is that mental events and human actions are part of causal flow of natural events. Anomalous Monism seems to be an epiphenomenalist thesis, because, in Anomalous Monism, anomaly of the mental rules out causal efficacy of the mental in physical world. (shrink)

Mental probability logic is a psychological competence theory about how humans interpret and reason about common-sense conditionals. Probability logic is proposed as an appropriate standard of reference for evaluating the rationality of human inferences. Common-sense conditionals are interpreted as “high” conditional probabilities, P(B|A) > .5. Probability logical accounts of nonmonotonic reasoning and inference rules like the modus ponens are explored. Categorical syllogisms with comparative and quantitative quantifiers are investigated. A series of eight experiments on human probabilistic reasoning in (...) the framework of the basic nonmonotonic system p corroborate the psychological plausibility of the proposed approach. (shrink)

It is widely agreed that generics tolerate exceptions. It turns out, however, that exceptions are tolerated only so long as they do not violate homogeneity: when the exceptions are not concentrated in a salient “chunk” of the domain of the generic. The criterion for salience of a chunk is cognitive: it is dependent on the way in which the domain is mentally represented. Findings of psychological experiments about the ways in which different domains are represented, and the actors affecting such (...) representations, account for judgments of generic sentences, facts which cannot be explained by linguistics alone. The reason for the homogeneity requirement itself is, in turn, also dependent on cognitive considerations. Generics express default rules, and psychological findings have shown that, the more homogeneous the domain, the easier it is for subjects to infer rules about it. Thus, cognitive results form a crucial part of a comprehensive account of the meaning of a linguistic expression. (shrink)

Psychophysiological correlations form the basis for different medical and scientific disciplines, but the nature of this relation has not yet been fully understood. One conceptual option is to understand the mental as “emerging” from neural processes in the specific sense that psychology and physiology provide two different descriptions of the same system. Stating these descriptions in terms of coarser- and finer-grained system states macro- and microstates, the two descriptions may be equally adequate if the coarse-graining preserves the possibility to (...) obtain a dynamical rule for the system. To test the empirical viability of our approach, we describe an algorithm to obtain a specific form of such a coarse-graining from data, and illustrate its operation using a simulated dynamical system. We then apply the method to an electroencephalographic recording, where we are able to identify macrostates from the physiological data that correspond to mental states of the subject. © 2009 American Institute of Physics.

Dogs display vast phenotypic diversity, including differences in height, skull shape, tail, etc. Yet, humans are almost always able to quickly recognize a dog, despite no single feature or group of features are critical to distinguish dogs from other objects/animals. In search of the mental activities leading human individuals to state “I see a dog”, we hypothesize that the brain might extract meaningful information from the environment using Ramsey sentences-like procedures. To turn the proposition “I see a dog” in (...) a Ramsey sentence, the term dog must be replaced by a long and complex assertion consisting only of observational terms, existential quantifiers and operational rules. The Ramsey sentence for “I see a dog” sounds: “There is at least an entity called dog which satisfies the following conditions: it is an animal, it has four legs, …, etc, …, and is something that I have in my sight”. We discuss the biological plausibility and the putative neural correlates of a Ramsey-like mechanism in the central nervous system. We accomplish a brain-inspired, theoretical neural architecture consisting of a parallel network that requires virtually no memory, is devoid of probabilistic choices and can analyze huge but finite amounts of unique visual details, combining them into a single conceptual output. In sum, Ramsey sentence stands for a versatile tool that can be used not just as a methodological device to cope with biophysical affairs, but also for a model to describe the real functioning of cognitive operations such as sensation and perception.

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)

There is a continuum between prototypical cases of rule use and prototypical cases of similarity use. A prototypical rule: (1) is explicitly represented, (2) can be verbalized, and (3) requires that the user selectively attend to a few features of the object, while ignoring the others. Prototypical similarity-use requires that: (1) the user should match the object to a mental representation holistically, and (2) there should be no selective attention or inhibition. Neural evidence supports prototypical rule-use. Most models of (...) categorization fall between the two prototypes. (shrink)

. In his work on language John Searle favors an Austinian approach that emphasizes the speech act as the basic unit of meaning and communication, and which sees speaking a language as engaging in a rule-governed form of behavior. He couples this with a strident opposition to cognitivist approaches that posit unconscious rule following as the causal basis of linguistic competence. In place of unconscious rule following Searle posits what he calls the Background, comprised of nonintentional (nonrepresentational) mental phenomena. (...) I argue that these two aspects of his philosophy of language cannot be reconciled. In order to preserve his view of language as a rule-governed activity, he must embrace the cognitivist idea of unconscious rule following. Finally, I try to show how such an accommodation would be far less traumatic to Searle’s philosophical system than it might otherwise seem. (shrink)

Perruchet & Vinter's article, for all its breadth and scope, has several deep problems: specifically, an eccentric notion of rule, a narrow notion of what it means for a mental instantiation to be abstract, and a failure to take into account fundamental principles of evolutionary biology. While not the only problems, these three are sufficient to seriously weaken their arguments.
