The Affective Foundations of Moral Cognition and Justification: A Naturalistic Account Public

Abstract

This interdisciplinary project focuses on the vital role of emotion in moral cognition and the ramifications for a psychologically realistic approach to normative ethical reasoning. Convergent evidence from a variety of scientific fields, including psychology, neuroscience, and primatology, indicates that affect directs our intuitive judgments, grounds our empathic capacities, orients our moral reasoning, and motivationally binds us to our assessments. These descriptive findings shed light on several prominent metaethical issues, including the simulation/‘theory theory' debate, the weakness of will question, and the realism/antirealism controversy. With regard to the simulation/‘theory theory' debate concerning the neuropsychological underpinnings of our Theory of Mind (ToM) capacities, it appears that both sides are partially correct. As reflected by the distinctive empathic impairments characteristic of psychopathy and autism and supporting neurological evidence, Affective ToM and Cognitive ToM rely on unique underlying mechanisms, with the former incorporating more simulation-based processing and the latter involving more theory-based operations. In Chapter 3, it is argued that weakness of will occurs less frequently in the case of intuitive judgments, as opposed to assessments based on conscious moral reasoning, since intuitive judgments are typically linked to relatively more intense emotion and thus carry greater motivational force. Furthermore, I contend in Chapter 4 that a Darwinian genealogy of our ethical sensibility poses a serious epistemological challenge to traditional versions of moral realism, a view that there are ‘independent' ethical truths that apply irrespective of our subjective feelings. The practical implications of this evolutionary debunking are limited, however, because our tendency to impute greater practical authority to ethical norms is emotionally-rooted, persisting in the absence of a belief in moral realism. Finally, in my last chapter, I endorse and expand John Rawls' method of wide reflective equilibrium as a psychologically realistic approach to ethical justification that accords with the empirical evidence regarding the affective foundations of moral judgment and motivation. To my awareness, this enhanced version of Rawls' method is the first developed normative reasoning procedure of its kind within the sentimentalist tradition--a justificatory approach that attributes normative weight to our moral feelings without, however, automatically justifying them.
