Our brains were designed for tribal life, for getting along with a select group of others and for fighting off everyone else. But modern times have forced the world’s tribes into a shared space, resulting in epic clashes of values along with unprecedented opportunities. As the world shrinks, the moral lines that divide us become more salient and more puzzling. We fight over everything from tax codes to gay marriage to global warming, and we wonder where, if at all, we (...) can find our common ground. (shrink)

This chapter discusses neurocognitive work relevant to moral psychology and the proposition that innate factors make important contributions to moral judgment. It reviews various sources of evidence for an innate moral faculty, before presenting brain-imaging data in support of the same conclusion. It is argued that our moral thought is the product of an interaction between some ‘gut-reaction’ moral emotions and our capacity for abstract reflection.

Scientific realism is the optimistic view that modern science is on the right track: that the world really is the way our best scientific theories describe it. In his book, Stathis Psillos gives us a detailed and comprehensive study which restores the intuitive plausibility of scientific realism. We see that throughout the twentieth century, scientific realism has been challenged by philosophical positions from all angles: from reductive empiricism, to instrumentalism and to modern sceptical empiricism. _Scientific Realism_ explains that the history (...) of science does not undermine the arguments for scientific realism, but instead makes it reasonable to accept scientific realism as the best philosophical account of science, its empirical success, its progress and its practice. Anyone wishing to gain a deeper understanding of the state of modern science and why scientific realism is plausible, should read this book. (shrink)

Moral Tribes: Emotion, Reason, and the Gap between Us and Them. . ???aop.label???. doi: 10.1080/09515089.2013.871618.

Intuition—spontaneous, nondeliberative assessment—has long been indispensable in theoretical and practical philosophy alike. Recent research by psychologists and experimental philosophers has challenged our understanding of the nature and authority of moral intuitions by tracing them to “fast,” “automatic,” “button-pushing” responses of the affective system. This view of the affective system contrasts with a growing body of research in affective neuroscience which suggests that it is instead a flexible learning system that generates and updates a multidimensional evaluative landscape to guide decision and (...) action. With this latter view in mind, I revisit some of the classic hypothetical scenarios used in experimental moral psychology. (shrink)

According to Joshua Greene’s influential dual process model of moral judgment, different modes of processing are associated with distinct moral outputs: automatic processing with deontological judgment, and controlled processing with utilitarian judgment. This paper aims to clarify and assess Greene’s model. I argue that the proposed tie between process and content is based on a misinterpretation of the evidence, and that the supposed evidence for controlled processing in utilitarian judgment is actually likely to reflect generic deliberation which, ironically, is incompatible (...) with a utilitarian outlook. This alternative proposal is further supported by the results of a recent neuroimaging study we have done. (shrink)

At the end of a thoughtful article on the future of nuclear war, Wiesner and York concluded that: "Both sides in the arms race are... confronted by the dilemma of steadily increasing military power and steadily decreasing national security. It is our considered professional judgment that this dilemma has no technical solution. If the great powers continue to look for solutions in the area of science and technology only, the result will be to worsen the situation.".

In some cases people judge it morally acceptable to sacrifice one person’s life in order to save several other lives, while in other similar cases they make the opposite judgment. Researchers have identified two general factors that may explain this phenomenon at the stimulus level: (1) the agent’s intention (i.e. whether the harmful event is intended as a means or merely foreseen as a side-effect) and (2) whether the agent harms the victim in a manner that is relatively “direct” or (...) “personal”. Here we integrate these two classes of findings. Two experiments examine a novel personalness/directness factor that we call personal force, present when the force that directly impacts the victim is generated by the agent’s muscles (e.g., in pushing). Experiments 1a and b demonstrate the influence of personal force on moral judgment, distinguishing it from physical contact and spatial proximity. Experiments 2a and b demonstrate an interaction between personal force and intention, whereby the effect of personal force depends entirely on intention. These studies also introduce a method for controlling for people’s real-world expectations in decisions involving potentially unrealistic hypothetical dilemmas. (shrink)

Traditional theories of moral development emphasize the role of controlled cognition in mature moral judgment, while a more recent trend emphasizes intuitive and emotional processes. Here we test a dual-process theory synthesizing these perspectives. More specifically, our theory associates utilitarian moral judgment (approving of harmful actions that maximize good consequences) with controlled cognitive processes and associates non-utilitarian moral judgment with automatic emotional responses. Consistent with this theory, we find that a cognitive load manipulation selectively interferes with utilitarian judgment. This interference (...) effect provides direct evidence for the influence of controlled cognitive processes in moral judgment, and utilitarian moral judgment more specifically. (shrink)

It has been claimed that the recent wave of neuroscientific research into the physiological underpinnings of our moral intuitions has normative implications. In particular, it has been claimed that this research discredits our deontological intuitions about cases, without discrediting our consequentialist intuitions about cases. In this paper I demur. I argue that such attempts to extract normative conclusions from neuroscientific research face a fundamental dilemma: either they focus on the emotional or evolved nature of the psychological processes underlying deontological intuitions, (...) in which case the arguments rely on a blatantly fallacious inference, or they appeal to the (alleged) moral irrelevance of the factors to which deontological intuitions respond, in which case the neuroscientific results end up playing no role in the overall argument.

Experimental philosophy uses experimental research methods from psychology and cognitive science in order to investigate both philosophical and metaphilosophical questions. It explores philosophical questions about the nature of the psychological world - the very structure or meaning of our concepts of things, and about the nature of the non-psychological world - the things themselves. It also explores metaphilosophical questions about the nature of philosophical inquiry and its proper methodology. This book provides a detailed and provocative introduction to this innovative field, (...) focusing on the relationship between experimental philosophy and the aims and methods of more traditional analytic philosophy. Special attention is paid to carefully examining experimental philosophy's quite different philosophical programs, their individual strengths and weaknesses, and the different kinds of contributions that they can make to our philosophical understanding. Clear and accessible throughout, it situates experimental philosophy within both a contemporary and historical context, explains its aims and methods, examines and critically evaluates its most significant claims and arguments, and engages with its critics.

In this essay, I draw on Haidt’s and Baron’s respective insights in the service of a bit of philosophical psychoanalysis. I will argue that deontological judgments tend to be driven by emotional responses, and that deontological philosophy, rather than being grounded in moral reasoning, is to a large extent3 an exercise in moral rationalization. This is in contrast to consequentialism, which, I will argue, arises from rather different psychological processes, ones that are more “cognitive,” and more likely to involve genuine (...) moral reasoning. These claims are strictly empirical, and I will defend them on the basis of the available evidence. Needless to say, my argument will be speculative and will not be conclusive. Beyond this, I will argue that if these empirical claims are true, they may have normative implications, casting doubt on deontology as a school of normative moral thought. (shrink)

In this essay I argue that ordinary moral thought and language is, while very natural, highly counterproductive and that as a result we would be wise to change the way we think and talk about moral matters. First, I argue on metaphysical grounds against moral realism, the view according to which there are first order moral truths. Second, I draw on principles of moral psychology, cognitive science, and evolutionary theory to explain why moral realism appears to be true even though (...) it is not. I then argue, based on the picture of moral psychology developed herein, that realist moral language and thought promotes misunderstanding and exacerbates conflict. I consider a number of standard views concerning the practical implications of moral anti-realism and reject them. I then sketch and defend a set of alternative revisionist proposals for improving moral discourse, chief among them the elimination of realist moral language, especially deontological language, and the promotion of an anti-realist utilitarian framework for discussing moral issues of public concern. I emphasize the importance of revising our moral practices, suggesting that our entrenched modes of moral thought may be responsible for our failure to solve a number of global social problems.
