Whether psychopathy is a mental disease or illness can affect whether psychiatrists should treat it and whether it could serve as the basis for an insanity defense in criminal trials. Our understanding of psychopathy has been greatly improved in recent years by new research in psychology and neuroscience. This illuminating research enables us to argue that psychopathy counts as a mental disease on any plausible account of mental disease. In particular, Szasz's and Pickard's eliminativist views and Sedgwick's social constructivist account (...) of mental illness that might exclude psychopathy are not plausible, and there is no reason to exclude psychopathy under Boorse's and Scadding's biomedical accounts, Wakefield's harmful dysfunction account, and the DSM-IV-TR objective harm account of mental disease. The basic reason is that psychopathy involve neural dysfunction that increases risk of serious harm and loss to people with psychopathy. (shrink)

In this paper, our goal is to survey some of the legal contexts within which violence risk assessment already plays a prominent role, explore whether developments in neuroscience could potentially be used to improve our ability to predict violence, and discuss whether neuropredictive models of violence create any unique legal or moral problems above and beyond the well worn problems already associated with prediction more generally. In Violence Risk Assessment and the Law, we briefly examine the role currently played by (...) predictions of violence in three high stakes legal contexts: capital sentencing, civil commitment hearings, and sexual predator statutes. In Clinical vs. Actuarial Violence Risk Assessment, we briefly examine the distinction between traditional clinical methods of predicting violence and more recently developed actuarial methods, exemplified by the Classification of Violence Risk software created by John Monahan and colleagues as part of the MacArthur Study of Mental Disorder and Violence [1]. In The Neural Correlates of Psychopathy, we explore what neuroscience currently tells us about the neural correlates of violence, using the recent neuroscientific research on psychopathy as our focus. We also discuss some recent advances in both data collection and data analysis that we believe will play an important role when it comes to future neuroscientific research on violence. In The Potential Promise of Neuroprediction, we discuss whether neuroscience could potentially be used to improve our ability to predict future violence. Finally, in The Potential Perils of Neuroprediction, we explore some potential evidentiary, constitutional, and moral issues that may arise in the context of the neuroprediction of violence.

Neuroscience has been proposed for use in the legal system for purposes of mind reading, assessment of responsibility, and prediction of misconduct. Each of these uses has both promises and perils, and each raises issues regarding the admissibility of neuroscientific evidence.

Much of the literature from political psychology has focused on the negative traits that are positively associated with affective polarization—e.g., animus, arrogance, distrust, hostility, and outrage. Not as much attention has been focused on the positive traits that might be negatively associated with polarization. For instance, given that people who are intellectually humble display greater openness and less hostility towards conflicting viewpoints (Krumrei-Mancuso & Rouse, 2016; Hopkin et al., 2014; Porter & Schumann, 2018), one might reasonably expect them to be (...) less polarized. -/- We ran two studies designed to explore the relationship between various forms of humility and polarization. Our chief finding is that people who value humility are prone to what we are calling epistemic polarization—that is, judging the epistemic traits of contrapartisans negatively—which in turn plays a role in polarization more generally. Not only are contrapartisans deemed to have the wrong moral and political beliefs, they are also viewed as less humble and more arrogant, close-minded, and irrational. This makes matters even worse when it comes to the growing partisan divide. In light of our findings, we believe that the novel concept of epistemic polarization that we introduce is a promising target for further investigation. (shrink)

We show that a quantum system admits hidden variables if and only if there is a rich set of states which satisfy a Bayesian rule. The result is proved using a relationship between Bayesian type states and dispersion-free states. Various examples are presented. In particular, it is shown that for classical systems every state is Bayesian and for traditional Hilbert space quantum systems no state is Bayesian.

1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

Hegel introduced the Phenomenology of Mind as a work on the problem of knowledge. In the first chapter, entitled “Sense Certainty, or the This and Meaning,” he concluded that knowledge cannot consist of an immediate awareness of particulars ). The tradition discusses sense certainty in terms of this failure of immediate knowledge without, however, specifically addressing the problem of reference. Yet reference is distinct from knowledge in the sense that while there can be no knowledge of objects without reference, there (...) may be reference without knowledge. If that is the case, then the failure of immediate knowledge does not entitle us to conclude anything about the success or failure of reference. It is not surprising, then, that a few scholars have begun to examine sense certainty primarily as a thesis about reference. (shrink)

In a series of recent papers, Walter Sinnott-Armstrong has used findings in social psychology to put pressure on the claim that our moral beliefs can be non-inferentially justified. More specifically, he has suggested that insofar as our moral intuitions are subject to what psychologists call framing effects, this poses a real problem for moral intuitionism. In this paper, we are going to try to add more fuel to the empirical fire that Sinnott-Armstrong has placed under the feet of (...) the intuitionist. Along the way, we first provide an overview of what Sinnott-Armstrong calls the Master Argument against intuitionism. Then we examine some of the literature on framing effects—especially as it pertains to moral philosophy. Finally, we present the results of a new study which create yet another hurdle intuitionists must clear if they want to motivate their view. It appears that in addition to being influenced by framing effects, our moral intuitions are also influenced by an actor–observer bias as well—a bias whereby we hold other people to different moral standards than we would hold ourselves even if we were in the same situation. If we’re right, the burden is on the moral intuitionist to explain why we should have faith in our moral intuitions despite the gathering evidence concerning their seeming unreliability. And by our lights, this is something that simply cannot be done from the armchair. (shrink)

This paper has two components. The first, longer component (sec. 1-6) is a critical exposition of Armstrong’s views about the metaphysics of mathematics, as they are presented in Truth and Truthmakers and Sketch for a Systematic Metaphysics. In particular, I discuss Armstrong’s views about the nature of the cardinal numbers, and his account of how modal truths are made true. In the second component of the paper (sec. 7), which is shorter and more tentative, I sketch an alternative (...) account of the metaphysics of mathematics. I suggest we insist that mathematical truths have physical truthmakers, without insisting that mathematical objects themselves are part of the physical world. (shrink)

One of the most interesting recent attempts to interpret the peculiarities of Plotinus's philosophy is that of Bréhier in his ‘La Philosophie de Plotin’. His thesis, contained in the last four chapters of the work, is that Plotinus, instead of being simply the continuator of the Greek rationalist tradition, is the founder of modern European Idealism, or, perhaps more accurately, Pantheism. ‘Avec Plotin nous saisissons done le premier chatnon d'une tradition religieuse qui n'est pas moins puissante au fond en Occident (...) que la tradition chretienne …’. He is the spiritual ancestor of Spinoza and Hegel. It is interesting in passing to compare this view with that of Dean Inge, for whom Plotinus is the spiritual begetter of S. Thomas Aquinas. The divergences of modern interpreters of the Plotinian metaphysic are often both amusing and suggestive. (shrink)

Direct awareness, or the immediate, on-the-spot, noninferential access that we have to some of our mental-occurrence instances, is a kind of "secondary consciousness." It often happens, in addition, that direct awareness itself is conscious, meaning that one is also directly aware of being so aware. This is "tertiary consciousness." Indeed, absent tertiary consciousness, one could not base actions on what is mentally occurring to one now. Although Armstrong held that "subliminal introspection" suffices for purposive mental activity, tertiary consciousness would (...) seem to be necessary for carrying out such activity because purposive mental activity essentially involves choosing what mentally to do next on the basis of "introspective" feedback. One must be aware of whatever it may be that one is basing one’s actions on. Adopting, in place of "subliminal introspection," either one of two Jamesian hypotheses could save Armstrong from having to posit nonconscious purposive mental activities. (shrink)

In this issue, Walter Sinnott-Armstrong and Franklin G. Miller argue that what makes killing wrong, when it is wrong, is not that it ends life, but that it causes complete and irreversible disability—what they call total disability. They hold that the wrongness of killing should be explained by reference to the harm that killing causes to the person who dies. And the only harm of this sort that killing causes, they argue, is the harm of being totally disabled: once (...) one is totally disabled, there is no further harm to one in losing one's life. It is no worse to be dead, and thus totally disabled, than it is to be totally disabled but alive.In fact, Sinnott-Armstrong and Miller concede that the story may be more complicated than this. For example, it may be that what makes killing wrong, when it is wrong, is not that it causes harm, but that it is intended to do so, or that it violates a right which protects against harm. But either way, harm plays a crucial role in explaining the wrongness of killing, and the relevant harm, they claim, is the harm of being disabled, not that of losing one's life.The Authors’ argument has important implications for medical ethics. Their view implies that killing a person need not be wrong when that person is already completely and irreversibly disabled. This suggests, for example, that the dead donor rule in organ donation is mistaken. Contrary to the rule, it could be morally permissible to harvest organs from a living donor provided that the donor is totally disabled. Harvesting organs will kill the donor, but it will not disable her, since the donor has no abilities left to lose.Four …. (shrink)

Cassirer’s Die Platonische Renaissance in England und die Schule von Cambridge, of which the present work is a translation, was first published in 1932; it therefore necessarily takes no account of the mass of work on the English Catholic humanists of the Renaissance, beginning with Chambers’s Thomas More, and on 17th-century English religious thought, which has appeared in the last 20 years. This may partly account for the rather old-fashioned impression which the book produces. Cassirer still understood More, Colet, (...) and Erasmus after the manner of Seebohm’s Oxford Reformers, a book which he frequently quotes. But the misunderstanding which, so it seems to the present reviewer, makes the picture given by the book as a whole a distorted one, goes rather deeper. The eminent neo-Kantian author appears to think that authentic Christian orthodoxy is Augustinianism, and Augustinianism interpreted in the manner of Jansenius or Calvin. Hence the philosophy of St. Thomas, to which he gives some fine and understanding pages, appears to him as a heroic but unsuccessful attempt to establish a Christian humanism on an Aristotelian basis which had little lasting effect ; he is led to represent such great and profoundly Catholic figures of the Renaissance as Cardinal Nicholas of Cusa and St. Thomas More as fundamentally unorthodox; in dealing with his main subject, the Cambridge Platonists, he presents ideas which any Catholic brought up in an enlightened Thomist tradition will naturally recognize as a normal part of his own religious and philosophical inheritance as if they were in the deepest disaccord with the teachings of orthodox Christianity; and he greatly exaggerates the opposition between the Cambridge Platonists and their Puritan contemporaries.

Walter Sinnott-Armstrong has recently criticized moral intuitionism by bringing to light some compelling empirical evidence indicating that we are unreliable at forming moral judgments non-inferentially. The evidence shows that our non-inferentially arrived-at moral convictions are subject to framing effects; that is, they vary depending on how the situation judged is described. Thomas Nadelhoffer and Adam Feltz, following in Sinnott-Armstrong's footsteps, have appealed to research indicating that such judgments are also subject to actor-observer bias; that is, they vary (...) depending on whether the situation judged includes the judger as an actor in, or an observer of, the situation. The accuracy of this empirical evidence will not be challenged in what follows. What will be called into question is its purported relevance for moral intuitionism. To that end we will consider a version of moral intuitionism developed by Iris Murdoch that not only accommodates but essentially relies on the existence of various kinds of distorting factors including framing effects and actor-observer bias.

Analytic particularism claims that judgments of moral wrongness are about particular acts rather than general principles. Metaphysical particularism claims that what makes true moral judgments true is not general principles but nonmoral properties of particular acts. Epistemological particularism claims that studying particular acts apart from general principles can justify beliefs in moral judgments. Methodological particularism claims that we will do better morally in everyday life if we look carefully at each particular decision as it arises and give up the search (...) for a complete moral theory. This paper raises problems for each of these versions of particularism. (shrink)

In his last book, David Armstrong sets out his metaphysical system in a set of concise and lively chapters each dealing with one aspect of the world. He begins with the assumption that all that exists is the physical world of space-time. On this foundation he constructs a coherent metaphysical scheme that gives plausible answers to many of the great problems of metaphysics. He gives accounts of properties, relations, and particulars; laws of nature; modality; abstract objects such as numbers; (...) and time and mind. (shrink)

When making decisions, humans can observe many kinds of information about others' activities, but their effects on performance are not well understood. We investigated social learning strategies using a simple problem-solving task in which participants search a complex space, and each can view and imitate others' solutions. Results showed that participants combined multiple sources of information to guide learning, including payoffs of peers' solutions, popularity of solution elements among peers, similarity of peers' solutions to their own, and relative payoffs from (...) individual exploration. Furthermore, performance was positively associated with imitation rates at both the individual and group levels. When peers' payoffs were hidden, popularity and similarity biases reversed, participants searched more broadly and randomly, and both quality and equity of exploration suffered. We conclude that when peers' solutions can be effectively compared, imitation does not simply permit scrounging, but it can also facilitate propagation of good solutions for further cumulative exploration.

First published in 1985, D. M. Armstrong's original work on what laws of nature are has continued to be influential in the areas of metaphysics and philosophy of science. Presenting a definitive attack on the sceptical Humean view, that laws are no more than a regularity of coincidence between stances of properties, Armstrong establishes his own theory and defends it concisely and systematically against objections. Presented in a fresh twenty-first-century series livery, and including a specially commissioned preface written (...) by Marc Lange, illuminating its continuing importance and relevance to philosophical enquiry, this influential work is available for a new generation of readers.

All contentious moral issues--from gay marriage to abortion and affirmative action--raise difficult questions about the justification of moral beliefs. How can we be justified in holding on to our own moral beliefs while recognizing that other intelligent people feel quite differently and that many moral beliefs are distorted by self-interest and by corrupt cultures? Even when almost everyone agrees--e.g. that experimental surgery without consent is immoral--can we know that such beliefs are true? If so, how? These profound questions lead to (...) fundamental issues about the nature of morality, language, metaphysics, justification, and knowledge. They also have tremendous practical importance in handling controversial moral questions in health care ethics, politics, law, and education. Sinnott-Armstrong here provides an extensive overview of these difficult subjects, looking at a wide variety of questions, including: Are any moral beliefs true? Are any justified? What is justified belief? The second half of the book explores various moral theories that have grappled with these issues, such as naturalism, normativism, intuitionism, and coherentism, all of which are attempts to answer moral skepticism. Sinnott-Armstrong argues that all these approaches fail to rule out moral nihilism--the view that nothing is really morally wrong or right, bad or good. Then he develops his own novel theory,--"moderate Pyrrhonian moral skepticism"--which concludes that some moral beliefs can be justified out of a modest contrast class but no moral beliefs can be justified out of an extreme contrast class. While explaining this original position and criticizing alternatives, Sinnott-Armstrong provides a wide-ranging survey of the epistemology of moral beliefs. (shrink)

This paper explores whether brain images may be admitted as evidence in criminal trials under Federal Rule of Evidence 403, which weighs probative value against the danger of being prejudicial, confusing, or misleading to fact finders. The paper summarizes and evaluates recent empirical research relevant to these issues. We argue that currently the probative value of neuroimages for criminal responsibility is minimal, and there is some evidence of their potential to be prejudicial or misleading. We also propose experiments that will (...) directly assess how jurors are influenced by brain images. (shrink)
