The crucial problem in the philosophy of psychiatry is to determine under which conditions certain behaviors, mental states, and personality traits should be regarded as symptoms of mental illnesses. Participants in the debate can be placed on a continuum of positions. On the one side of the continuum, there are naturalists who maintain that the concept of mental illness can be explained by relying on the conceptual apparatus of the natural sciences, such as biology and neuroscience. On the other side (...) of the continuum, there are normativists who maintain that the appropriate characterization of the concept of mental illness cannot avoid reference to epistemic, moral and other social values. Although, this article is primarily an introduction to the debate, we stress the importance of the normativist positions. (shrink)

Recently it has been argued that certain neuropsychological findings on the decision-making, instrumental learning, and moral understanding in psychopathic offenders offer reasons to consider them not criminally responsible, due to certain epistemic and volitional impairments. We reply to this family of arguments, that collectively we call the irresponsibility of the psychopath argument (IPA for short). This type of argument has a premise that describe or prescribe the deficiencies that grant or should grant partial or complete criminal exculpation. The other premise (...) contends that neuropsychological evidence shows that psychopaths have incapacitates that are sufficient to ascribe complete or partially exculpatory deficiencies. The focus of our criticism is this latter premise. We argue that it requires that psychopathy should correlate significantly with certain rational incapacities that manifest across contexts. We show that the available neuropsychological data do not support the claim that psychopaths have such general exculpatory incapacities. (shrink)

We argue that philosophy has an important role to play in bridging certain social practices with certain scientific advancements. Specifically, we describe such a role by focusing on the issue of how and whether neuropsychological data concerning psychopathic offenders reflect on their criminal culpability. We offer some methodological requirements for this type of philosophical application. In addition, we show how it might help in addressing the problem of determining the criminal responsibility of psychopathic offenders.

The aim of this paper is to analyze, from a philosophical perspective, the scientific robustness of the construct of psychopathy as measured by the Psychopathy Checklist Revised that was developed by Robert Hare (1991; 2003). The scientific robustness and validity of classifications are topics of many debates in philosophy of science and philosophy of psychiatry more specifically. The main problem consists in establishing whether scientific classifications reflect natural kinds where the concept of a natural kind refers to the existence of (...) some objective divisions in nature that do not depend exclusively on subjective judgments of the classifier. The construct of psychopathy is especially interesting since the diagnosis of psychopathy has substantial social consequences. In the light of the recent debates regarding the problem of natural kinds in philosophy of psychiatry, we advocate the following distinction between two types of scientific classifications: natural and practical kinds. Natural kinds refer to those categories that are united by common causal mechanisms or properties. Practical kinds refer to categories that fulfill some practical classificatory goals such as prediction. We argue that the construct of psychopathy can fulfill the role of a practical kind. In addition, we contend that our current scientific knowledge about psychopathy does not allow us to conclude that this category is a natural kind. (shrink)

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

Frank Jackson’s knowledge argument and different conceivability arguments, advanced by Saul Kripke, David Chalmers and Joseph Levine, conclude that consciousness involves non-physical properties or properties that cannot be reductively accounted for in physical terms. Some physicalists have replied to these objections by means of different versions of the phenomenal concept strategy. David Chalmers has responded with the master argument, a reasoning that, if successful, would undermine any reasonable version of the phenomenal concept strategy. In this paper, I argue that the (...) master argument does not advance the debate between the supporters of the anti-physicalist arguments and those of the phenomenal concept strategy. (shrink)

A pressing and difficult practical problem concerns the general issue of the right social response to offenders classified as having antisocial personality disorder. This paper approaches this general problem by focusing, from a philosophical perspective, on the still relevant but more approachable question whether psychopathic offenders are morally responsible. In particular, I investigate whether psychopaths possess moral understanding. A plausible way to approach the last question requires a satisfactory philosophical interpretation of the empirical evidence that appears to show that psychopaths (...) fail to draw the distinction between conventional and moral norms. Specifically, I will consider a recent philosophical debate polarized between supporters of rationalist and sentimentalist accounts of moral understanding. These opponents have discussed whether the case of psychopathy offers empirical support for their account and undermine the rival view. I will argue that the available empirical data leave the outcome of this discussion indeterminate. However, this implies that both these principal theories of moral understanding, if independently motivated, would imply that psychopaths have certain deficits that might affect their moral understanding and, consequently, their moral responsibility. (shrink)

One of the philosophical discussions stimulated by the recent scientific study of psychopathy concerns the mental illness status of this construct. This paper contributes to this debate by recommending a way of approaching the problem at issue. By relying on and integrating the seminal work of the philosopher of psychiatry Bill Fulford, I argue that a mental illness is a harmful unified construct that involves failures of ordinary doing. Central to the present proposal is the idea that the notion of (...) failure of ordinary doing, besides the first personal experience of the patient, has to be spelled out also by referring to a normative account of idealised conditions of agency. This account would have to state in particular the conditions which are required for moral responsibility. I maintain that psychopathy is a unified enough construct that involves some harms. The question whether the condition involves also a failure of ordinary doing, as this notion is understood in this paper, is not investigated here. (shrink)

Psychopathy, executive functions, and neuropsychological data: a response to Sifferd and Hirstein.

We argue that the mandatory moral bioenhancement of psychopaths is justified as a prescription of social morality. Moral bioenhancement is legitimate when it is justified on the basis of the reasons of the recipients. Psychopaths expect and prefer that the agents with whom they interact do not have certain psychopathic traits. Particularly, they have reasons to require the moral bioenhancement of psychopaths with whom they must cooperate. By adopting a public reason and a Kantian argument, we conclude that we can (...) justify to a psychopath being the recipient of mandatory moral bioenhancement because he has a reason to require the application of this prescription to other psychopaths.

The issue whether psychopathic offenders are practically rational has attracted philosophical attention. The problem is relevant in theoretical discussions on moral psychology and in those concerning the appropriate social response to the crimes of these individuals. We argue that classical and current experiments concerning the instrumental learning in psychopaths cannot directly support the conclusion that they have impaired instrumental rationality, construed as the ability for transferring the motivation by means-ends reasoning. In fact, we defend the different claim that these experiments (...) appear to show that psychopaths in certain circumstances are not aware of the relevant means for their ends. Moreover, we suggest how further empirical research could help to settle the issue. (shrink)

In this chapter we argue that Robert Hare's psychopathy checklist revised (PCL-R) offers a construct of psychopathy that is valid enough for philosophical investigations of the moral and legal responsibility of psychopathic offenders.

Physicalism in philosophy of mind is the doctrine that mental states and processes, if they are something, are physical states and processes. Notoriously, Frank Jackson has attacked physicalism with the knowledge argument. This paper does not consider whether the knowledge argument is successful. Instead, the author argues that the ability reply to the knowledge argument fails. The central assumption of this objection is that Mary, by having colour experiences, acquires a set of abilities rather than new beliefs as required by (...) the knowledge argument. Against the ability reply, it is maintained that Mary on her release acquires new beliefs about objects looking the same colour. As a preliminary, it is shown, against an important criticism of the knowledge argument, that we can make sense of what Mary knows about colour experience when in the black-and-white laboratory.

How psychopaths and their capacity for moral action are viewed is not only philosophically interesting but is also important and relevant for policy. The philosophical discussion of psychopathy has focussed upon the psychological faculties that are prerequisites for moral responsibility and empirical findings regarding psychopathy that are relevant to philosophical accounts of moral understanding and motivation. However, there are legitimate worries about whether psychopathy is a robust scientific construct, and there are risks attached to reifying psychopathy or other psychiatric constructs. (...) We defend the concept of psychopathy by pointing out the relevance of empirical studies about it for our ordinary practices of ascribing moral responsibility and folk psychological accounts of moral understanding and motivation.

b is collection focuses on conceptual issues that arise within the theoretical dimension of psychiatry. In particular, the invited contributions centre on the nature of psychiatric classification and explanation by addressing important methodological issues. Two strategies are exemplified here. Either the authors directly contribute to foundational issues in psychiatry concerning the nature of psychiatric classification and explanation; or they provide a conceptual analysis that can play a role in developing adequate theories of specific psychiatric disorders.

Certain conceivable situations figure as premises in arguments for the conclusion that conscious experiences have nonphysical properties or qualia. Frank Jackson's knowledge argument considers the hypothetical scientist Mary, who despite having complete scientific knowledge of colour vision, supposedly lacks knowledge of qualia. Both Saul Kripke's and David Chalmers' modal arguments involve zombies, conceivable creatures physically identical to us who lack qualia. Several physicalists have replied to all these objections by endorsing the phenomenal concept reply. Without trying to undermine this reply (...) in general, I argue that recent versions of it proposed by John Perry and David Papineau are unsatisfactory. (shrink)

Gorući i težak praktički problem vezan je uz opće pitanje ispravnog društvenog odgovora na prijestupnike klasificirane kao osobe s antisocijalnim poremećajem ličnosti. Članak prilazi ovom općem problemu fokusirajući se, iz filozofske perspektive, na još uvijek važno ali lakše dohvatljivo pitanje jesu li psihopatski prijestupnici moralno odgovorni. Posebno se istražuje imaju li psihopati mogućnost moralnog razumijevanja. Vjerodostojni pristup posljednjem pitanju zahtijeva zadovoljavajuću filozofsku interpretaciju empirijskog dokaza koji pokazuje da psihopati ne uspijevaju naći razliku između konvencionalnih i moralnih normi. Preciznije, uzet ću (...) u obzir nedavnu filozofsku raspravu polariziranu između pobornika racionalističkog i sentimentalističkog objašnjenja moralnog razumijevanja. Ovi su suparnici otvorili raspravu nudi li slučaj psihopatije empirijsku potporu za njihovo objašnjenje i potkopava suparnički pogled. U radu tvrdim da dostupni empirijski podaci ostavljaju ishod ove rasprave neodlučenim. To implicira da bi obje teorije moralnog razumijevanja, ako su neovisno motivirane, uzele u obzir psihopate kao osobe koje imaju određene nedostatke koje bi mogle utjecati na njihovo moralno razumijevanje a stoga i na njihovu moralnu odgovornost.

Bortolotti's book offers a significant and successful example of the emerging “new” analytic philosophy of psychiatry. Methodologically, it exemplifies a fruitful two-way interaction between philosophy and empirical investigation. Empirical results from cognitive sciences and clinical research are used to constrain philosophical assumptions about beliefs and delusions. Rigorous philosophical argumentation is employed to clarify and adjudicate theoretical interpretations of empirical data concerning the nature of delusion. This work is surely an obligatory reading for those seriously interested in delusions, beliefs and, more (...) in general, the application of an empirically informed philosophy of mind to psychiatry.

Boran Berčić, in the second volume of his recent book "Filozofija" , offers two responses to David Chalmers’s conceivability or modal argument against physicalism. This latter argument aims at showing that zombies, our physical duplicates who lack consciousness, are metaphysically possible, given that they are conceivable. Berčić’s first response is based on the principle of the uniformity of nature that states that causes of a certain type will always cause effects of the same type. His second response is based on (...) the assumption that the basic statements of physicalism in philosophy of mind are or should be contingently true. I argue that if Berčić’s first defence is aimed at the conceivability of zombies, it is unsatisfactory. Moreover, I argue that a quite similar argument, offered by John Perry in his book "Knowledge, Possibility and Consciousness" , is afflicted by a similar problem. Nevertheless, under a more plausible interpretation, Berčić’s argument might be taken to attack the metaphysical possibility of zombies. This version of the argument might be effective and has the merit to point out a so far overlooked link between the discussion of the Chalmers’s conceivability arguments against physicalism and the modal strength of causal links and natural laws. Then, I argue that Berčić’s second defence of physicalism, which cannot be combined consistently with his first one, in any case, should not be formulated in the terms of contingent physicalism.

The philosophical contributes in the volume offer several considerations for the conclusion that psychopaths offenders should not be considered morally responsible for their crimes. We situate this conclusion within wider philosophical debates and indicate relevant directions of further research.

Un problème pratique pressant et difficile est lié à la problématique générale de la réponse sociale adéquate concernant les délinquants qualifiés comme souffrant de trouble de la personnalité antisociale. L’article se penche sur le problème en se focalisant, d’un point de vue philosophique, sur la question – tout aussi pertinente mais plus abordable – de savoir si les délinquants psychopathes sont moralement responsables. Plus particulièrement, il s’interroge si les psychopathes possèdent une conscience morale. Une approche crédible de la question pré-citée (...) exige une interprétation philosophique satisfaisante de la preuve empirique indiquant que les psychopathes ne parviennent pas à distinguer les normes conventionnelles et morales. Plus précisément, j’examinerai un débat philosophique récent polarisé entre les partisans de l’explication rationaliste et ceux de l’explication sentimentaliste de la conscience morale. Ces opposants ont ouvert le débat sur la question de savoir si le cas de la psychopathie offre un appui empirique à leur explication et s’il mine la position de leurs opposants. Dans cette étude, j’affirme que les preuves empiriques disponibles laissent l’issue de ce débat incertain. Ceci implique que les deux théories de la conscience morale, si elles étaient motivées indépendamment, considèreraient les psychopathes comme des personnes dont certaines inaptitudes pourraient influer sur leur conscience morale et par conséquent leur responsabilité morale.

Psychopaths have emotional and rational impairments that can be expressed in persistent criminal behaviour. UK and US law has not traditionally excused disordered individuals for their crimes citing these impairments as a cause for their criminal behaviour. Until now, the discussion of whether psychopaths are morally responsible for their behaviour has usually taken place in the realm of philosophy. However, in recent years, this debate has been informed by scientific and psychiatric advancements, fundamentally so with the development of Robert Hare's (...) diagnostic tool, the Psychopathy Checklist. Responsibility and Psychopathy explores the moral responsibility of psychopaths. It engages with problems at the interface between law, psychiatry, and philosophy, and is divided into three parts offering relevant interdisciplinary background information to address this main problem. The first part discusses the public policy and legal responses to psychopathy. It offers an introduction to the central practical issue of how public policy should respond to psychopathy, providing insights for those arguing about the responsibility of psychopaths. The second part introduces recent scientific advancements in the classification, description, explanation, and treatment of psychopathy. The third part of the volume includes chapters covering the most significant dimensions of philosophical debate on the moral and criminal responsibility of psychopaths. Exploring one of the most contentious topics of our time, this book will be fascinating reading for psychiatrists, philosophers, criminologists, and lawyers. Readership: Psychiatrists, philosophers, psychologists, criminologists. (shrink)

Frank Jackson’s knowledge argument is a very influential piece of reasoning that seeks to show that colour experiences constitute an insoluble problem for science. This argument is based on a thought experiment concerning Mary. She is a vision scientist who has complete scientific knowledge of colours and colour vision but has never had colour experiences. According to Jackson, upon seeing coloured objects, Mary acquires new knowledge that escapes her complete scientific knowledge. He concludes that there are facts concerning colour experiences (...) that scientific knowledge can neither describe nor explain. Specifically, these facts involve the occurrence of certain non-physical properties of experiences that he calls qualia. The present research considers whether a plausible formulation of the hypothesis that science can accommodate colour experiences is threatened by a version of the knowledge argument. The specific formulation of this problem has two motivations. Firstly, before investigating whether the knowledge argument raises a problem for the claim that science can account for colour experiences, we need a plausible formulation of this claim. I argue that the idea that science can accommodate colour experiences can be formulated as the modest reductionism hypothesis. Roughly speaking, this is the hypothesis that a science that can be explanatory interfaced with current physics of ordinary matter can account for conscious experiences. Secondly, an unintelligible premise figures in Jackson’s version the knowledge argument. Namely, it is assumed that Mary possesses a complete scientific knowledge. Nevertheless, the type of strategy involved in Jackson’s argument can be used to target modest reductionism. By considering contemporary psychophysics and neuroscience, I characterise Mary’s scientific knowledge. First, this characterisation is intelligible. In fact, it is elaborated on the basis of descriptions and explanations of colour experiences involved in current physics and neuroscience. Second, a supporter of modest reductionism can assume that the scientific knowledge ascribed to Mary might account for colour experiences. The main conclusion of the present research is that our version of the knowledge argument fails to threaten the modest reductionism hypothesis. In fact, I endorse what can be called the “two ways of thinking” reply to the knowledge argument. According to this response, the knowledge argument shows that there are different ways of thinking about colour experiences. One way of thinking is provided by scientific knowledge. The other way of thinking is provided by our ordinary conception of colour experiences. However, the existence of these two ways of thinking does not imply the existence of facts and properties that escape scientific knowledge. It might be the case that the ordinary way of thinking about colour experience concerns facts and properties described and explained by science. The principal conclusion of the research results from two investigations. The first line of research aims to reveal and evaluate the implicit assumptions that figure in the knowledge argument. The main body of the research is dedicated to this task. The principal result of this investigation is that the knowledge argument must rely on an account of introspective knowledge of colour experiences. I argue that an inferential model of introspection provides such account. On this model, Mary’s capacity to hold beliefs about her colour experiences when she sees coloured objects requires her mastery of colour concepts. The second main investigation seeks to justify the two ways of thinking strategy. As many opponents and supporters have recently started to realise, this strategy might be charged with being ad hoc. I offer a distinctive justification of this reply to the knowledge argument. Assuming the account of introspection mentioned above, the existence of visual recognitional colour concepts might justify this strategy. A person possesses these concepts when she is able to determine the colours of objects simply by having visual experiences. (shrink)

There is widespread debate in contemporary philosophy of mind over the place of conscious experiences in the natural world – where the latter is taken to be broadly as described and explained by such sciences as physics, chemistry and biology; while conscious experiences encompass pains, bodily sensations, perceptions, feelings and moods. Many philosophers and scientists, who endorse physicalism or materialism, maintain that these mental states can be completely described and explained in natural terms. Frank Jackson’s knowledge argument is a very (...) influential objection to physicalism and, thus, to such an optimistic view about the scientific treatability of conscious experiences. According to the knowledge argument, we can know facts about our colour experiences that are not physical facts. At the heart of this book lies a response to the knowledge argument that aims to defend a version of physicalism, that the author calls modest reductionism. This reply is based on the endorsement of the phenomenal concept strategy. According to this response, the knowledge argument cannot prove that there are non-physical facts. Instead, it can only show that there are ways of thinking about colour experiences that are based on phenomenal concepts that differ from scientific concepts. The author argues for the superiority of the phenomenal concept strategy over other influential physicalist replies to the knowledge argument. However, he criticises some recent physicalist accounts of phenomenal concepts and develops his own distinctive theory of these concepts. (shrink)
