Adaptationist accounts of morality attempt to explain the evolution of morality in terms of the selective advantage that judging in moral terms secured for our ancestors (e.g. Ruse 1998; Joyce 2006; Street 2006). So-called by-product explanations of morality have been presented as an alternative to adaptationist accounts (e.g. Prinz 2009; Ayala 2010; cf. Darwin 2004/1871). In assessing the relationship between adaptationist and by-product accounts, care must be taken to distinguish several related but importantly different notions: innateness, adaptation, exaptation, spandrel, and (...) by-product.

This dissertation examines the psychology of moral judgment and its implications for normative ethics and metaethics. Recent empirical findings in moral psychology, such as the impact of emotions, intuitions, and situational factors on moral judgments, have sparked a debate about whether ordinary moral judgments are systematically error-prone. Some philosophers, such as Peter Singer and Joshua Greene, argue that these findings challenge the reliability of moral intuitions and support more "reasoned", consequentialist approaches over deontological ones. The first part of the dissertation (...) reviews these provocative findings and the philosophical reactions to them, which often invoke the notion of 'moral relevance' - the idea that some factors shaping moral judgments are morally irrelevant. The second part develops a psychological account of moral relevance, drawing on theories of the moral domain, the role of emotions, and models of moral cognition. This account reveals the complex interplay of intuitive and reasoned processes in generating impressions of moral relevance. The final part reevaluates the philosophical discussions in light of this psychological understanding. It contends that the evolutionary background of moral intuitions does not necessarily render them inadequate, and that both deontological and consequentialist judgments likely depend on evolved intuitions to a significant degree. Furthermore, the tendency to dismiss certain influences on moral judgment as irrelevant can itself be explained psychologically. Considering the psychological account presented, mind-independent accounts of morality become less plausible. The dissertation concludes that while empirical moral psychology reveals important constraints on normative theorizing, it does not decisively favor consequentialism over deontology. To assess the significance of empirical-scientific findings for ethics, a nuanced understanding of the origins of moral judgments is nevertheless indispensable. (shrink)

Meu objetivo aqui é mostrar o quão fácil é lidar com o utilitarismo de preferências e maximizar a utilidade pessoal quando somos confrontados com um pequeno conjunto de ações possíveis. Uma vez que a reduzimos o escopo das ações possíveis, ou seja, ao que é factível, nós também nos tornamos facilmente capazes de identificar o comportamento adequado ou inadequado, ao menos em termos da maximização racional das preferências desejadas.

One of the primary motivations behind moral anti-realism is a deep-rooted scepticism about moral knowledge. Moral realists attempt counter this worry by sketching a plausible moral epistemology. One of the most radical proposals in the recent literature is that we know moral facts by perception – we can literally see that an action is wrong, etc. A serious objection to moral perception is the causal objection. It is widely conceded that perception requires a causal connection between the perceived and the (...) perceiver. But, the objection continues, we are not in appropriate causal contact with moral properties. Therefore, we cannot perceive moral properties. This papers demonstrates that the causal objection is unsound whether moral properties turn out to be secondary, natural properties; non-secondary, natural properties; or non-natural properties. 1.

One popular reason for rejecting moral realism is the lack of a plausible epistemology that explains how we come to know moral facts. Recently, a number of philosophers have insisted that it is possible to have moral knowledge in a very straightforward way—by perception. However, there is a significant objection to the possibility of moral perception: it does not seem that we could have a perceptual experience that represents a moral property, but a necessary condition for coming to know that (...) X is F by perception is the ability to have a perceptual experience that represents something as being F . Call this the ‘Representation Objection’ to moral perception. In this paper I argue that the Representation Objection to moral perception fails. Thus I offer a limited defense of moral perception. (shrink)

The affective though and the intuition in moral judgment has been discovered lately (Haidt, 2001). This article analyzes the Moral Judgment theory (Kohlberg, 1964) and the basic logical operations (Piaget, 1950). The rational stages with a few intervention of emotion have been historically assumed by moral judgment theory, which judges the affective as a mistaken notion and as a simple cognitive extension (Greene & Haidt, 2002). This paper demonstrates that the Piagetian basic operations, seriation and categorization are applicable to an (...) affective system. In addition, the intuition is a moral determinant and finally, that neuronal activity confirms an intuitional cognition for the resolution of social problems. It is expected that the present deliberation guides and stimuli researches on the intuition and emotion in moral judgment. (shrink)

Jesse Prinz develops a naturalistic metaethical theory with which he purports to sidestep ‘Hume's law’ by demonstrating how, on his theory, in describing what our moral beliefs commit us to we can determine what our moral obligations are. I aim to show that Prinz does not deliver on his prescriptive promise – he does not bridge the is–ought gap in any meaningful way. Given that Prinz goes on to argue that (1) his moral psychology highlights fundamental shortcomings in ‘traditional’ normative (...) ethical theories, (2) that moral progress is possible, despite the relativistic implications of his own position, and (3) that this undermining of the is–ought gap should hold true on any naturalistic metaethical theory, the extent to which his project succeeds becomes significant.

Recent work in moral psychology that claims to show that human beings make moral judgements on the basis of multiple, divergent moral foundations has been influential in both moral psychology and moral philosophy. Primarily, such work has been taken to undermine monistic moral theories, especially those pertaining to the prevention of harm. Here, I call one of the most prominent and influential empirical cases for moral pluralism into question, namely that of Jonathan Haidt and his colleagues. I argue that Haidt (...) et al.’s argument is not as strong as it is often made out to be, given significant problems with the design of one of the key experiments used to ground the claim that there are divergent moral foundations across cultures. The flaws that I point out pose a significant challenge to Haidt et al.’s findings and have a detrimental impact on subsequent work based on this immensely influential experiment. Accordingly, I argue that both empirical and normative claims made on the basis of Haidt et al.’s findings should be treated with caution. I conclude by making some suggestions as to how some of the problems that I point out might be addressed. (shrink)

Many philosophers assume that philosophical theories about the psychological nature of moral judgment can be confirmed or disconfirmed by the kind of evidence gathered by natural and social scientists (especially experimental psychologists and neuroscientists). I argue that this assumption is mistaken. For the most part, empirical evidence can do no work in these philosophical debates, as the metaphorical heavy-lifting is done by the pre-experimental assumptions that make it possible to apply empirical data to these philosophical debates. For the purpose of (...) this paper, I emphasize two putatively empirically-supported theories about the psychological nature of moral judgment. The first is the Sentimental Rules Account, which is defended by Shaun Nichols. The second is defended by Jesse Prinz, and is a form of sentimentalist moral relativism. I show that both of the arguments in favour of these theories rely on assumptions which would be rejected by their philosophical opponents. Further, these assumptions carry substantive moral commitments and thus cannot be confirmed by further empirical investigation. Because of this shared methodological assumption, I argue that a certain form of empirical moral psychology rests on a mistake. (shrink)

The role of religion in clinical ethics consultations is contested. The religion of the ethics consultant _can be_ an important part of the consultation process and improve the quality of a consultation. Practicing neighbor love leads to empathy, which not only can improve the quality of ethics consultations but also creates a space for religion to be part of, but not imposed on, the consultation. The practice of empathy will build trust, rapport, and an intersubjective connection that improves the quality (...) of the consultation.

In this paper, I use an example from the history of philosophy to show how independently defining each side of a pair of contrary predicates is apt to lead to contradiction. In the Euthyphro, piety is defined as that which is loved by some of the gods while impiety is defined as that which is hated by some of the gods. Socrates points out that since the gods harbor contrary sentiments, some things are both pious and impious. But “pious” and (...) “impious” are contrary predicates; they cannot simultaneously characterize the same thing. Euthyphro changes his definition, but the problem of recognizing emotional ambivalence is only side-stepped. I go on to show how contemporary philosophers run into a similar problem. According to Prinz, something is good if and only if we harbor positive sentiments towards it and bad if and only if we harbor negative sentiments towards it. Thus, if we are ambivalent towards something (if we harbor both positive and negative sentiments towards it), then it is both good and bad. Like “pious” and “impious”, “good” and “bad” are contraries. Next, according to the fitting-attitude theory first elaborated by Brentano and favored by contemporary meta-ethicists like Blackburn, Brandt, Ewing, Garcia, Gibbard, McDowell, and Wiggins, something is good if and only if it is a fitting (appropriate) object of approbation, and something is bad if and only if it is a fitting (appropriate) object of disapprobation. I argue that moral ambivalence is sometimes appropriate, i.e., that the correct response to some things is to both love and hate them. Hence, according to the fitting-attitudes theory, some things are both good and bad. I conclude by discussing a variety of ways in which the problem of ambivalence may be solved, suggesting that attitudes of approbation and disapprobation be further individuated by the reasons for them.

It is highly consensual that we can perceive so-called low-level properties such as shape, color, motion, spatial location, and illumination through vision. But it’s more controversial whether the contents of visual perception can reach beyond the limits of weakness and involve high-level properties as well. By high-level property, it’s meant properties such as natural/artificial/functional kind, causality, dispositional properties, gender, roughness, aesthetic properties, bodily sensations, states of mind, agency features, action features, and moral properties. In this dissertation, setting Susanna Siegel's rich (...) content thesis as a framework and relying on her method of phenomenal contrast as a way of discovering the contents, I am intending to assess an account of perceiving moral properties. I will impose two objections against this model: The first one invokes the ignored role of imagination and recollection in the method and generally targets the method of contrast. The second one invokes the thesis of phenomenal holism and targets specifically the machinery of drawing contrast in the proposed moral pair. Finally, I’ll conclude that this account of moral perception, as well as other phenomenal-contrast-based accounts, is not tenable. -/- . (shrink)

The central question for this dissertation is, how do we do moral philosophy well from within a broadly naturalist framework? Its main goal is to lay the groundwork for a methodological approach to moral philosophy that integrates traditional, intuition-driven approaches to ethics with empirical approaches that employ empirical data from biology and cognitive science. Specifically, it explores what restrictions are placed on our moral theorizing by findings in evolutionary biology, psychology, neuroscience, and other fields, and how we can integrate this (...) data while still offering a fully normative account of ethics. To that end, the dissertation explores the methodological assumptions behind both traditional and more empirical or experimental approaches to ethics, to find where these assumptions cannot be properly supported and need to be re-examined. Chapter 1 explores the science-based objections that have been raised to traditional approaches, with a particular focus on questions concerning the reliability of moral intuitions. Chapter 2 examines three fundamental assumptions supporting the empirical approach to moral philosophy, and how those assumptions ultimately do not fit with how we ought to understand the project of ethics. In chapter 3, I discuss the fact/value distinction, and the restrictions that are placed on our moral theorizing by our commitment to this distinction. Chapter 4 offers a defense of ‘companions in guilt’ arguments, and uses these arguments to draw an analogy between moral philosophy and epistemology that will be used to help defend moral philosophy against empirical debunking arguments. Chapter 5 explores the ways in which epistemologists’ methods of incorporating empirical data into their research while maintaining the normativity of their accounts can be adapted to allow moral philosophers to do the same, and brings together the various methodological concerns addressed up to this point to lay out a methodological approach I call empirically-informed moral philosophy.

Contemporary ethics and moral philosophy need a kind of revision due to their negligence in human moral capacities, ordinary life, and humans’ expectations of ethics. The assumptions and presuppositions of ethics result in their current unsatisfactory status. In this paper, we first explore and criticize those presuppositions. Then, instead of introducing ideal presuppositions of ethics, we introduce folk ethics and its components in order to show that contemporary ethics and moral philosophy should always begin with folk ethics. The most important (...) advantage of folk ethics is its realistic foundation, which in turn will produce better results. (shrink)

Prof. Miščević has long been an ardent defender of the use of thought experiments in philosophy, foremost metaphysics, epistemology and philosophy of mind. Recently he has, in his typically sophisticated manner, extended his general account of philosophical thought-experimenting to the domain of normative politics. Not only can the history of political philosophy be better understood and appreciated, according to Miščević, when seen as a more or less continuous, yet covert, practice of thought-experimenting, the very progress of the discipline may crucially (...) depend on finding the right balance between the constraints of (biological, psychological, economic, political, and so on) reality and political-moral ideals when we set to design our basic political notions and institutions. I have much less confidence in this project than prof. Miščević does. As a subspecies of moral TE, political TE share all their problems plus exhibit some of their own. In the paper, I present and discuss two types of evidence that threaten to undermine political philosophers’ trust in thought-experiments and the ethical/political intuitions elicited by them: (i) the dismal past record of thought-experimentation in moral and political philosophy; and (ii) the variety, prevalence, and stubbornness, of bias in ordinary social/political judgment.
