It has long been claimed that moral judgements are dominated by reason. In recent years, however, the tide has turned. Many psychologists and philosophers now hold the view that there is a close empirical association between moral judgements and emotions. In particular, they claim that emotions (1) co-occur with moral judgements, (2) causally influence moral judgements, (3) are causally sufficient for moral judgements, and (4) are causally necessary for moral judgements. At first sight these hypotheses seem well-supported. In this paper (...) I show, however, that appearances are deceiving. If one considers the relevant scientific studies in detail, one finds that in many interpretations the above hypotheses are either not supported or even contradicted by the available evidence. This conclusion is significant both for our understanding of moral judgements qua empirical phenomena and for normative ethics and metaethics. (shrink)

In recent years, a proliferation of books about empathy, cooperation and pro-social behaviours (Brooks, 2011a) has significantly influenced the discourse of the life-sciences and reversed consolidated views of nature as a place only for competition and aggression. In this article I describe the recent contribution of three disciplines – moral psychology (Jonathan Haidt), primatology (Frans de Waal) and the neuroscience of morality – to the present transformation of biology and evolution into direct sources of moral phenomena, a process here named (...) the ‘moralization of biology’. I conclude by addressing the ambivalent status of this constellation of authors, for whom today ‘morality comes naturally’: I explore both the attractiveness of their message, and the problematic epistemological assumptions of their research programmes in the light of new discoveries in developmental and molecular biology.

In bioethics, the first decade of the twenty-first century was characterized by the emergence of interest in the ethical, legal, and social aspects of neuroscience research. At the same time an ongoing extension of the topics and phenomena addressed by neuroscientists was observed alongside its rise as one of the leading disciplines in the biomedical science. One of these phenomena addressed by neuroscientists and moral psychologists was the neural processes involved in moral decision-making. Today both strands of research are often (...) addressed under the label of neuroethics. To understand this development we recalled literature from 1995 to 2012 stored in the Mainz Neuroethics Database (i) to investigate the quantitative development of scientific publications in neuroethics; (ii) to explore changes in the topics of neuroethics research within the defined time interval; (iii) to illustrate the interdependence of different research topics within the neuroethics literature; (iv) to show the development of the distribution of neuroethics research on peer-reviewed journals; and (v) to display the academic background and affiliations of neuroethics Researchers ...

Different versions of moral projectivism are delineated: minimal, metaphysical, nihilistic, and noncognitivist. Minimal projectivism (the focus of this paper) is the conjunction of two subtheses: (1) that we experience morality as an objective aspect of the world and (2) that this experience has its origin in an affective attitude (e.g., an emotion) rather than in perceptual faculties. Both are empirical claims and must be tested as such. This paper does not offer ideas on any specific test procedures, but rather undertakes (...) the important preliminary task of clarifying the content of these subtheses (e.g., what is meant by "objective"? what is meant by "experience"?). Finally, attention is given to the relation between (a) acknowledging that the projectivist account might be true of a token moral judgment and (b) maintaining moral projectivism to be true as a general thesis.

En este trabajo se analizan dos modos paradigmáticos en que en la actualidad se comprende la relación entre las disciplinas que se encuentran implicadas en la tarea de la neuroética, en su carácter de neurociencia de la ética. Particularmente se critica la forma que toma la interdisciplinariedad en estos dos modelos. En el primer caso se señala que la tarea de reflexión filosófica no da lugar a que la evidencia neurocientífica pueda modificar de modo importante los presupuestos teóricos en que (...) se funda tal reflexión. En el segundo caso, por el contrario, el papel dado al componente empírico, necesario a la neuroética, obtura la reflexión ético-filosófica.In this paper, I analyze two paradigmatic contemporary ways of understanding the relation between the disciplines involved in neuroethics. In particular, I criticize the form interdisciplinarity takes in these two models. It is pointed out that, according to one of these, the philosophical reflection does not allow neuroscientific evidence to influence in any significant way the theoretical presupositions of that reflection. According to the second model, on the contrary, the role of the empirical component, essential to neuroethics, rather blocks the ethical and philosophical reflection. (shrink)

Motivational internalism postulates a necessary connection between moral judgments and motivation. In arguing for and against internalism, metaethicists traditionally appeal to intuitions about cases, but crucial cases often yield conflicting intuitions. One way to try to make progress, possibly uncovering theoretical bias and revealing whether people have conceptions of moral judgments required for noncognitivist accounts of moral disagreement, is to investigate non-philosophers' willingness to attribute moral judgments. A pioneering study by Shaun Nichols seemed to undermine internalism, as a large majority (...) of subjects were willing to attribute moral understanding to an agent lacking moral motivation. However, our attempts to replicate this study yielded quite different results, and we identified a number of problems with Nichols' experimental paradigm. The results from a series of surveys designed to rule out these problems show that people are more willing to attribute moral understanding than mor.. (shrink)

What motivates the benevolent or charitable agent is regard for another’s good or well-being, but talk about regard for others’ good or well- being is simply talk about benevolence or charity in different terms. Yet Hume clearly holds that the regard for another’s good is a motive to produce benevolent acts that is distinct from a sense of their benevolence. So what is the difference? ‘Well’, one might say, ‘intuitively, rights are very different from wellbeing.’ Yes indeed. And that, I (...) shall contend, is Hume’s point. My general contention is that Hume’s discussion of justice is in fact an attack on that concept of rights we think of as having motivated the American and French revolutions, a concept that is still (deplorably in my view) prevalent. I think the very fact that it is so prevalent and so sanctified by its position in the American Constitution has blinded most readers to the power and plausibility of Hume’s attack, which I shall try to defend.

The aim of this article is to discuss the conditions under which functional neuroimaging can contribute to the study of higher cognition. We begin by presenting two case studies—on moral and economic decision making—which will help us identify and examine one of the main ways in which neuroimaging can help advance the study of higher cognition. We agree with critics that functional magnetic resonance imaging (fMRI) studies seldom “refine” or “confirm” particular psychological hypotheses, or even provide details of the neural (...) implementation of cognitive functions. However, we suggest that neuroimaging can support psychology in a different way—namely, by selecting among competing hypotheses of the cognitive mechanisms underlying some mental function. One of the main ways in which neuroimaging can be used for hypothesis selection is via reverse inferences, which we here examine in detail. Despite frequent claims to the contrary, we argue that successful reverse inferences do not assume any strong or objectionable form of reductionism or functional locationism. Moreover, our discussion illustrates that reverse inferences can be successful at early stages of psychological theorizing, when models of the cognitive mechanisms are only partially developed.

This thesis inquires into our ‘human nature’ through an interdisciplinary approach that considers some of the radical changes in intellectual thought at those key points in Western culture in which this concept has been centrally deployed. The broad historical sweep that this study covers finds the preoccupation with defining who we are and what we are capable of inextricably linked with the focus, at most of the pivotal moments examined, on a dominant impulse to conceive human beings as moral creatures.
