Researchers who argue that moral judgment is based on emotions (`emotion-backers') and those who believe that it is based on reasoning and deliberation (`reasoning-backers') have both struggled to account for the notorious moral deviance of incarcerated psychopaths. Emotion-backers, such as Jonathan Haidt, focus on psychopaths' lack of a affect,or defciencies in particular emotions, such as sympathy. Reasoning-backers, such as Lawrence Kohlberg, focus instead on psychopaths' de cient reasoning. Both accounts offer separate descriptions of what goes wrong in the disorder, but (...) neither can fully explain psychopathic moral deviance. The moral account that I built, bridges these accounts in an attempt to better and more fully describe the empirical data available on psychopathic moral judgment. I argue that their judgment is best explained with a dual-process account of moral judgment that incorporates a large system of moral emotions as well as integrates multiple bases of morality, such as concerns of fairness, harm, and purity. It is only by focusing on both the reasoning and emotional de cits in psychopaths that we can begin to understand psychopaths' use of utilitarian reasoning, general population psychopaths, and psychopaths' di erential presence in the prison popu- lation. All of these issues are best described using a dual-process account of moral judgment that incorporates a larger system of moral emotions than other accounts of morality as well as a pluralistic conception of moral foundations. I used psychopaths because their moral deviance can teach us about morality more broadly. By understanding the cognitive processes implicated in the moral judgment of psychopaths, I better explain how moral judgment works in the general population more broadly. My account of moral judgment has both theoretical and practical applications. Theoretically, it o ers a new dual-process paradigm for describing moral behaviour which bridges reasoning-based and emotion-based accounts. This description can explain both the moral deviance of psychopaths as well as, more broadly, moral judgment in non-psychopaths. Additionally, my theory challenges accounts of moral emotion that narrowly focus on speci c emotions, such as guilt or empathy. It in- stead integrates all emotions, including disgust, fear, and sympathy, and links speci c emotions to moral judgments. Practically, my paradigm of moral judgment encourages the development of new moral judgment measurements such as new self-report questionnaires of moral reasoning. According to my research, in order for these tools to accurately measure morality, they need to account for both emotion-based and reasoning-based judgments. (shrink)

Many contemporary philosophers are committed – either implicitly or explicitly – to Propositionalism about thought-experimental intuitions. According to this view, thought-experimental intuitions are phenomenally conscious, spontaneous, and non-theoretical; most importantly, Propositionalists claim that intuitions bear consciously accessible propositional content. The negative project of this essay is a critique of, the rejection of which is tantamount to rejecting Propositionalism. In addition, I propose an alternative position – namely, Interpretationalism. According to Interpretationalism, intuitions possess the features ascribed in -; however, they do (...) not bear consciously accessible propositional content. Instead, intuitions acquire cognitive significance by virtue of being interpreted in light of a subject’s background beliefs. (shrink)

This dissertation explores issues in the philosophy of psychology and metaphysics through the lens of the emotion of disgust, and its corresponding property, disgustingness. The first chapter organizes an extremely large body of data about disgust, imposes two constraints any theory must meet, and offers a cognitive model of the mechanisms underlying the emotion. The second chapter explores the evolution of disgust, and argues for the Entanglement thesis: this uniquely human emotion was formed when two formerly distinct mechanisms, one dedicated (...) to monitoring food intake and protecting against poisons, the other dedicated to protecting against parasitic infection, where driven together until they became functionally integrated. The third chapter explores the sorts of acquisition mechanisms that could give rise to the patterns of individual and cultural level variation we find with disgust elicitors. It argues for the Empathic Acquisition thesis, which holds that one important route for the social acquisition and transmission of disgust elicitors is linked to empathic recognition of facial expressions of the emotion. The fourth chapter builds on the Entanglement thesis, and embeds the emotion of disgust in gene-culture coevolutionary theory and the tribal instincts hypothesis. The Co-opt thesis is defended, which maintains that disgust was co-opted to play an important role in our moral psychology, particularly in our cognition of social norms and ethnic boundary markers. In doing so, however, it brings to bear many features initially linked to poisons and parasites. This explains the puzzling and troublesome character of moral judgments linked to disgust. After shifting gears from psychology to metaphysics, the fifth chapter recasts the Humean tradition of projectivism in the terminology of cognitive science. Using examples such as disgust, I argue that a psychologized projectivism is able to make sense of the idea that some properties are projected onto the world, rather than found there to begin with. The final chapter criticizes three other accounts of the property of disgustingness, two inspired by functionalism in the philosophy of color, one inspired by fittingness accounts in metaethics. I argue that none provide nearly as satisfactory account of the property as the psychologized projectivism articulated previously. (shrink)

Immediate striking feelings without any conscious inference are viewed as one of the sources of truth by many philosophers. It is often claimed that there is a long tradition in philosophy of viewing intuitive propositions as true without need for further justification, since the intuitiveness, for traditional philosophy, suggests that the proposition is self-evident. In philosophical discussions, it was extremely common for philosophers to argue for the intuitiveness of their theories. Contemporary philosophers have put increasing attention and effort into the (...) study of this methodology in philosophy. They explicitly use the term ‘intuition’ and ‘appealing to intuition’ to refer to such common practice in philosophy. Recently there are numerous papers discussing the topic of intuition, its reliability, evidential status, and what philosophy ought to be. These disputes have lasted for several decades and it seems the disputes may even continue for several more decades. Despite the excessive usage of the term ‘intuition’, there are still polarized attitudes towards intuition: not only on the question of whether we should appeal to intuition in doing philosophy, but also on what ‘intuition’ means. The latter problem, the divergence of understanding on ‘intuition’, seems to be the main factor causing endless disputes of this topic and it should be the problem primarily solved. There are philosophers who notice the problem that there is no general agreement on the accounts of intuition. However, surprisingly, most of them have not attempted to solve the problem, but just simply give their own accounts of intuition, or claim that it is improbable to have general agreement on the definition of ‘intuition’ instead. In fact, it is possible to have a general acceptable theory of intuition. The main aims of the thesis are to provide the method of seeking the good candidates for a general acceptable theory of intuition and to use the method in seeking one of the good theories. In order to achieve the goals, the thesis will provide the ground for the discussion, by specifying several features of intuition as the desiderata of a good theory; and examine several theories of intuition that have been offered in recent literature as example. We will find that, unfortunately, among the theories selected in philosophy, there still seems to be no satisfactory account of intuition. Nevertheless, there seems a promising account of intuition offered in psychology. The thesis will argue the psychological account is one of the good candidates of general acceptable theory of intuition. If not, we at least have a method of seeking the good theories of intuition.

A traditional pastime of philosophers is the analysis of rhetoric and the repudiation of sophistry. Nevertheless, some of what philosophers call sophistry might rather be a subtle repudiation of the traditional principles of rationality. In this paper I start by granting the Sophist his repudiation and outline some of the obstacles to settling the dispute between Sophists and Rationalists. I then suggest that we should distinguish pragmatic Sophism from nihilistic Sophism. In the hope of driving a wedge between these two (...) I illustrate the way in which the two are confounded when Sophism is advanced by use of a particular rhetorical manoeuvre and then give an argument against nihilistic Sophism which even a nihilistic Sophist should be persuaded by.

The debate between motivational judgment internalism and motivational judgment externalism focuses on whether a moral judgment is sufficient for motivation, or if an additional conative state is required. It is clear from the literature that internalists and exernalists have different intuitions regarding moral judgments. Most individuals, however, seem to hold a mix of internalist and externalist intuitions. My aim in this paper is to offer an approach to the issue that can account for this mix of intuitions. Drawing on the (...) work of psychologist Augusto Blasi, I suggest that a shift in focus from conative states to moral identity may be worthwhile. I argue that Blasi’s ‘self model’ can provide a straightforward story about moral judgments and motivation that makes sense of our mix of intuitions while accounting for many of the longstanding concerns of the debate between internalism and externalism.

Editorial introduction to the special issue of the European Journal of Analytic Philosophy.

This essay examines the recent Planet of the Apes films through the lens of recent research in primatology. The films lend imaginary support to primatologist Frans de Waal’s evolutionary moral sentimentalism; however, the movies also show that truly moral motions outstrip the cognitive capacities of the great apes. The abstract moral principles employed by the ape community in the movie require the ability to understand and apply a common underlying explanation to perceptually disparate situations; in contrast, recent research in comparative (...) psychology demonstrates that the great apes lack this capacity. Since the capacity for abstraction is required on even the most basic version of moral sentimentalism—Shaun Nichols’ sentimental rules account—the lack of the capacity for abstraction reveals a qualitative distinction between primate social behavior and human morality.
