Philosophers have urged that considerations about the psychopath’s capacity for practical rationality can help to advance metaethical debates. These debates include the role of rational faculties in moral judgment and action, the relationship between moral judgment and moral motivation, and the capacities required for morally responsible agency. I discuss how the psychopath’s capacity for practical reason features in these debates, and I identify several takeaway lessons from the relevant literature. Specifically, I show how the insights contained therein can illuminate the (...) complex structure of practical rationality, inform our standards for an adequate theory of practical reason, and frame our thinking about the significance of rational capacities in moral theory and social practice.

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)

There are some distinct methodological challenges, and possible pitfalls, for neuroethics when it evaluates neuroscientific results and links them to issues such as moral or legal responsibility. Some problems emerge in determining the requirements for responsibility. We will show how philosophical proposals in this area need to interact with legal doctrine and practice. Problems can occur when inferring normative implications from neuroscientific results. Other problems arise when it is not recognized that data about brain anatomy or physiology are relevant to (...) the ascription of responsibility only when they are significantly correlated with the psychological capacities contemplated by the legal formulations of responsibility. We will demonstrate this by considering two significant cases concerning psychopathy. Some paradigms that aim at measuring higher-order capacities, such as moral understanding, have limited validity. More robust paradigms for the study of learning in restricted controlled conditions, on the other hand, have limited ecological validity across individuals and context to be of any use for the law.

The harm usually associated with psychopathy requires therapeutically, legally, and ethically satisfactory solutions. Scholars from different fields have, thus, examined whether empirical evidence shows that individuals with psychopathic traits satisfy concepts, such as responsibility, mental disorder, or disability, that have specific legal or ethical implications. The present paper considers the less discussed issue of whether psychopathy is a disability. As it has been shown for the cases of the responsibility and mental disorder status of psychopathic individuals, we argue that it (...) is undecided whether psychopathy is a disability. Nonetheless, based on insights from disability studies and legislations, we propose that interventions to directly modify the propensities of individuals with psychopathic tendencies should be balanced with modifications of the social and physical environments to accommodate their peculiarities. We also suggest how this social approach in some practical contexts that involve non-offender populations might be effective in addressing some of the negative effects of psychopathy. (shrink)

Although many psychiatrists regard psychopathy as a coherent scientific construction, some clinicians and philosophers regard it as irrelevant. According to the latter, psychopathy is nothing more than a means of social control. The present study focuses on the issues of the neurological bases and moral responsibility related to psychopathy. While neuroscience aims to identify dysfunctions in psychopaths, action theory and ethics tend to vindicate the hypothesis of the moral irresponsibility of the psychopath. However, rather than reinforcing the concept of psychopathy, (...) recent results in neuroscience tend to stress its incoherence. Philosophical speculations on psychopaths’ responsibility are not sufficiently empirically informed and seem to announce endless ethical debates. (shrink)

Psychopathy attracts considerable interdisciplinary interest. The idea of a group of people with abnormal morality and interpersonal relations raises important philosophical, legal, and clinical issues. However, before engaging these issues, we ought to examine whether this category is scientifically grounded. We frame the issue in terms of the question whether ‘psychopathy’ designates a natural kind according to the cluster approaches. We argue that currently there is no sufficient evidence for an affirmative answer to this question. Furthermore, we examine three ways (...) of dealing with the category of psychopathy. We could eliminate the category, revise it, or subscribe to a more encompassing account of kinds, which could capture psychopathy as it is currently conceptualized. We argue that while a revision of the category of psychopathy is to be expected with empirical and theoretical advancements, we also emphasize its role in clinical and forensic research that makes it an important pragmatic kind.

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)

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.

In their paper “Is psychopathy a mental disease?”, Thomas Nadelhoffer and Walter Sinnott-Armstrong argue that according to any plausible account of mental disorder, neural and psychological abnormalities correlated with psychopathy should be regarded as signs of a mental disorder. I oppose this conclusion by arguing that at least on a naturalistically grounded account, such as Wakefield’s ‘Harmful Dysfunction’ view, currently available empirical data and evolutionary considerations indicate that psychopathy is not a mental disorder.

In accordance with a tradition depicting individuals with psychopathic functioning as morally blind, or even morally dead, discussions concerning their moral agency have for a long time neglected the analysis of volitional and conative aspects, whose contribution is nevertheless crucial in our understanding of their immoral actions. Based on the findings about the discrepancy that seems to occur, in this type of personality, between moral judgments and moral choices, we propose in this article to discuss the several theories that might (...) explain this gap between what the psychopath recognizes (or can, in a general way, recognizes) and what he does. After having presented the hypothesis - problematic in more than one sense - of a weakness of will associating psychopathy with acrasia, we expose the respective contributions of rationalist and neo-sentimentalist conceptions, before questioning the presupposition they share with theories of psychopathic incontinence. We argue that each of these three positions implicitly tends, with little empirical support, to ascribe to these dyssocial individuals a propensity to resort to some form of deliberative activity. An in-depth discussion of the prudential characteristics of psychopathy will lead us, on the contrary, to defend the idea that the immorality of those who suffer from it is, in most cases, only a collateral effect of a lack of appetite for the process of reflective self-evaluation. And we will see that there are strong reasons to believe that this lack of reflection - which accounts for many facets of the psychopathy construct while remaining compatible with the main explanatory models now favored to understand the psychopath’s moral decisions - is directly related to the (extremely poor) emotional life of psychopaths. We conclude by arguing that this way of linking emotional deficit and reflective impairment offers new perspectives for thinking about the different types of moral profiles found within the various forms of psychopathy that we suggest to distribute along a continuum on which levels of experiential deficiency extend.

Moral error theorists argue that moral thought and discourse are systematically in error, and that nothing is, or can ever be, morally permissible, required or forbidden. I begin by discussing how error theorists arrive at this conclusion. I then argue that if we accept a moral error theory, we cannot escape a pressing problem – what should we do next, metaethically speaking? I call this problem the ‘what now?’ problem, or WNP for short. I discuss the attempts others have made (...) to respond to the WNP, and in each case I show that the responses fail to be satisfying. I then propose a new response to the WNP, which I call revolutionary relativism. I define revolutionary relativism, explain why it is preferable to the existing responses to the WNP, and defend it against the most problematic objections I anticipate that opponents might raise. I conclude that revolutionary relativism succeeds where previous WNP responses fail, and that if we accept a moral error theory, we should become revolutionary relativists. (shrink)

Psychopathy, as articulated in Hare’s PCL-R, appears to reliably pick out a forensic category of troubled people. This chapter considers the use and utility of PCL-R by focussing upon two interrelated questions. Does philosophical investigation direct attention toward the issues that should interest us about psychopathy? Is being diagnosed as psychopathic or having ASPD clinically useful, as well as for judicial and sentencing purposes? While the research programmes that developed following the attention paid to psychopathy are warranted, more attention could (...) be directed to the varied nature of psychopathy and the presentations of it that Cleckley described in the Mask of Sanity. It is important to understand psychopathy as it affects lives, as well as a forensic problem. (shrink)
