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.

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.

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)

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)

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.

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.

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)

If there is a moral reason for A to do X, and if A cannot do X without doing Y, and if doing Y will enable A to do X, then there is a moral reason for A to do Y. This principle is plausible but mysterious, so it needs to be explained. It can be explained by necessary enabler consequentialism, but not by other consequentialisms or any deontological moral theory. Or so I argue. Frances Howard-Snyder objects that this argument (...) fails to establish consequentialism as understood by, because it fails to establish agent-neutrality. I respond by distinguishing consequentialism, which need not be agent-neutral, from utilitarianism, which claims agent-neutrality. Howard-Snyder also presents a schema for a non-consequentialist theory that is supposed to explain moral substitutability. I respond that her explanation cannot be completed without introducing incoherence into deontological moral theories. (shrink)

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)

A strong tradition in philosophy denies the possibility of moral dilemmas. Recently, several philosophers reversed this tradition. In this dissertation, I clarify some fundamental issues in this debate, argue for the possibility of moral dilemmas, and determine some implications of this possibility. ;In chapter I, I define moral dilemmas roughly as situations where an agent morally ought to adopt each of two alternatives but cannot adopt both. Moral dilemmas are resolvable if and only if one of the moral oughts overrides (...) the other. ;In chapter II, I criticize several opponents of moral dilemmas, including utilitarians, Kant, Aquinas, and Ross. My main criticism is that no opponent of moral dilemmas can adequately justify moral residue . ;Chapters III and IV concern the two main arguments against the possibility of moral dilemmas. First, the argument for 'ought' implies 'can' runs as follows. If the agent cannot adopt both, then it is not the case that the agent ought to adopt both. But the agent ought to adopt both, since the agent ought to adopt each . Thus, the defining judgements of a moral dilemma seem to imply a contradiction. In response, I argue that the relation between 'ought' and 'can' is not a logical implication but a conversational implicature. ;Chapter IV concerns the argument from 'ought' implies 'permitted': If the agent ought to adopt one alternative, then the agent is permitted to adopt that alternative, which means that it is not the case that the agent ought not to adopt that alternative. But the agent ought not to adopt that alternative, since the agent ought to adopt the other alternative and cannot adopt both. I respond that 'ought' does not logically imply but conversationally implicates 'permitted'. ;In chapter V, I argue that, despite recent claims, both moral realism and anti-realism are compatible with the possibility of moral dilemmas. Thus, there are several reasons to accept and no reasons to deny the possibility of moral dilemmas. (shrink)

In Moral Knowledge? New Readings in Moral Epistemology, editors Walter Sinnott-Armstrong and Mark Timmons bring together eleven specially commissioned essays by distinguished moral philosophers exploring the nature and possibility of moral knowledge. Each essay represents a major position within the exciting field of moral epistemology in which a proponent of the position presents and defends his or her view and locates it vis-a-vis competing views. The authors include established philosophers such as Peter Railton, Robert Audi, Richard Brandt, and Simon (...) Blackburn, as well as newer voices in the field. Topics covered include moral skepticism, moral truth, projectivism, contractarianism, coherentism, feminist views, quasi-realism, and pragmatism. The lively and clear selections do not presuppose specialized knowledge of philosophy, and the philosophical vocabulary used throughout the anthology is uniform, in order to facilitate understanding by those not familiar with the field. The first chapter includes a sustained critical discussion of the major views represented in the following chapters, thereby furnishing beginning students with appropriate background to understand the selections. The volume is further enhanced by an index and an extensive bibliography. An excellent text for undergraduate and graduate courses, Moral Knowledge provides the most up-to-date work on moral knowledge and justification. (shrink)

A survey of various candidates shows that there is no defensible moral principle that shows that individuals have an obligation to reduce their greenhouse gas emissions.

Our personal and political worlds are rife with arguments and disagreements, some of them petty and vitriolic. The inability to compromise and understand the opposition is epidemic today, from countries refusing to negotiate, to politicians pandering to their base. Social media has produced a virulent world where extreme positions dominate. There is much demonization of the other side, very little progress is made, and the end result is further widening of positions. How did this happen, and what might be done (...) to address it? Walter Sinnott-Armstrong says there is such a thing as a "good" argument: Reasonable arguments can create more mutual understanding and respect, and even if neither party is convinced by the other, compromise is still possible. Think Again shows the importance of good arguments and reveals common misunderstandings. Rather than a means to persuade other people or beat them in an intellectual competition, Sinnott-Armstrong sees arguments as an essential tool for constructive interaction with others. After showing how the failure of good arguments has led us to society's current woes, he shows readers what makes a good argument. In clear, lively, and practical prose, and with plentiful examples from politics, popular culture, and everyday life, Sinnott-Armstrong explains what defines an argument, identifies the components of good arguments as well as fallacies to avoid, and demonstrates what good arguments can accomplish. Armed with these tools, readers will be able to spot bad reasoning and bad arguments, and to advance their own views in a forceful yet logical way. These skills could even help repair our tattered civic culture. (shrink)

For much of the twentieth century, philosophy and science went their separate ways. In moral philosophy, fear of the so-called naturalistic fallacy kept moral philosophers from incorporating developments in biology and psychology. Since the 1990s, however, many philosophers have drawn on recent advances in cognitive psychology, brain science, and evolutionary psychology to inform their work. This collaborative trend is especially strong in moral philosophy, and these three volumes bring together some of the most innovative work by both philosophers and psychologists (...) in this emerging interdisciplinary field. The neuroscience of morality is in its infancy, with the first brain imaging studies of moral development undertaken only in 2001. The contributors to volume 3 sample the best work in this very new field, discussing a variety of approaches, including functional imaging, lesion studies, abnormal psychology, and developmental neuroscience. Each chapter includes an essay, comments on the essay by other scholars, and a reply by the author of the original essay. Topics include the neural basis of moral emotions and moral judgments as well as comparisons of normal adult moral judgments with those made by children, adolescents, and people with psychopathy, brain damage, and autism.

A complete moral theory should combine substantive ethics with metaethics, including moral semantics, moral epistemology, moral ontology, moral psychology, and the definition of morality. All of these topics and more are discussed with great clarity, insight, and originality in Copp’s remarkable book. Some of Copp’s positions are known from earlier articles, but his book reveals interconnections that increase the plausibility of each view separately and of the structure as a whole.

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.

We also propose experiments that will (...) directly assess how jurors are influenced by brain images. (shrink)

Whenever psychologists, neuroscientists, or philosophers draw conclusions about moral judgments in general from a small selected sample, they assume that moral judgments are unified by some common and peculiar feature that enables generalizations and makes morality worthy of study as a unified field. We assess this assumption by considering the six main candidates for a unifying feature: content, phenomenology, force, form, function, and brain mechanisms. We conclude that moral judgment is not unified on any of these levels and that moral (...) science should adopt a more fine-grained taxonomic approach that studies carefully defined groups of moral judgments.

Throughout the history of philosophy, skepticism has posed one of the central challenges of epistemology. Opponents of skepticism--including externalists, contextualists, foundationalists, and coherentists--have focussed largely on one particular variety of skepticism, often called Cartesian or Academic skepticism, which makes the radical claim that nobody can know anything. However, this version of skepticism is something of a straw man, since virtually no philosopher endorses this radical skeptical claim. The only skeptical view that has been truly held--by Sextus, Montaigne, Hume, Wittgenstein, and, (...) most recently, Robert Fogelin--has been Pyrrohnian skepticism. Pyrrhonian skeptics do not assert Cartesian skepticism, but neither do they deny it. The Pyrrhonian skeptics' doubts run so deep that they suspend belief even about Cartesian skepticism and its denial. Nonetheless, some Pyrrhonians argue that they can still hold "common beliefs of everyday life" and can even claim to know some truths in an everyday way. This edited volume presents previously unpublished articles on this subject by a strikingly impressive group of philosophers, who engage with both historical and contemporary versions of Pyrrhonian skepticism. Among them are Gisela Striker, Janet Broughton, Don Garrett, Ken Winkler, Hans Sluga, Ernest Sosa, Michael Williams, Barry Stroud, Robert Fogelin, and Roy Sorensen. This volume is thematically unified and will interest a broad spectrum of scholars in epistemology and the history of philosophy. (shrink)

Any theory of mind needs to explain mental causation. Kim’s exclusion argument concludes that non-reductive physicalism cannot meet this challenge. One classic reply is that mental properties capture the causally relevant level of generality, because they are insensitive to physical realization. However, this reply suggests downward exclusion, contrary to physicalism’s assumption of closure. This paper shows how non-reductive physicalists can solve this problem by introducing a contrastive account of causation with non-exhaustive contrasts. That view has independent justification, because it is (...) also needed to solve other puzzles. On this theory, both a mental property and its physical realizer can cause the same physical effect without lapsing into any problematic overdetermination when they cause that effect in contrast with distinct foils. This contrastive solution has advantages over previous accounts of mental causation and is defended against objections. (shrink)

The chapter focuses on the philosophical debate between moral motivational internalism and externalism. The author analyzes and thereby challenges the conceptual problems underlying this quarrel in relation to the apparent empirical findings on psychopathy. Major obstacles in making progress in this debate are conceptual and methodological problems. First, there is not a clear-cut and undisputed definition of moral internalism. Second, empirical results about a lack of moral judgment are not forthcoming, since it is not certain how to test such an (...) impairment, and also who is to count as psychopaths in the first place. In conclusion both externalists and internalists are wrong in some respect: internalists in that they see an internal connection between moral judgments and motivation, externalists in their rejection of internalism on grounds of findings about psychopathy.

Our thesis is that there is no moral requirement to refrain from emitting reasonable amounts of greenhouse gases solely in order to enjoy oneself. Joyriding in a gas guzzler provides our paradigm example. We first distinguish this claim that there is no moral requirement to refrain from joyguzzling from other more radical claims. We then review several different proposed objections to our view. These include: the claim that joyguzzling exemplifies a vice, causes or contributes to harm, has negative expected value, (...) exceeds our fair share of global emissions, and undermines political duties. We show why none of these objections succeeds and conclude that no good reason has yet been proposed that shows why joyguzzling violates a moral requirement. (shrink)

Expressivism faces four distinct problems when evaluative sentences are embedded in unassertive contexts like: If lying is wrong, getting someone to lie is wrong, Lying is wrong, so Getting someone to lie is wrong. The initial problem is to show that expressivism is compatible with - being valid. The basic problem is for expressivists to explain why evaluative instances of modus ponens are valid. The deeper problem is to explain why a particular argument like - is valid. The deepest problem (...) is to explain the meanings of evaluative conditionals like . Expressivists can solve the initial and basic problems simply by acknowledging that evaluative sentences have minimal truth aptness, but the deeper and deepest problems require more. The deepest problem cannot be solved even with the semantics of Gibbard and Blackburn, as is shown by an extension of Dreier’s hiyo argument. (shrink)
