MORAL RATIONALISM UNDER EMPIRICAL ASSESSMENT

2018

The first part of this introductory chapter introduces and discusses four core theses of moral rationalism: (i) the psychological thesis that reason is the source of moral judgment, (ii) the metaphysical thesis that moral requirements are constituted by the deliverances of practical reason, (iii) the epistemological thesis that moral requirements are knowable a priori, and (iv) the normative thesis that moral requirements entail valid reasons for action. We sketch different ¬– stronger and weaker – versions of each thesis, and tentatively examine whether specific versions of the different theses can be recombined into attractive rationalist packages, in which the various strands are mutually supporting. The chapter’s second part provides an overview of the contributions included in this volume.

In this paper I will analyze John McDowell's broad account of practical rationality and moral reasons, which he displays mainly in his articles "Are Moral Requirements Hypothetical Imperatives?" (1978) and "Might There Be External Reasons?" (1995). My main aim is to argue that from a philosophical perspective, no less than from an empirical one, McDowell's account of practical rationality is not a realistic one. From a philosophical point of view, I will argue that his intellectualist account is not convincing; and if we consider his virtue-ethical ideal of practical rationality in light of the model of human cognition, we also realize that moral behavior is not immune to cognitive biases and does not always flow from robust traits of character like virtues. At the same time, this puts at stake his strong thesis of moral autonomy-the idea that with the 'onset of reason' moral beings are no longer determined by 'first nature' features.

Empirical research paints a dismal portrayal of the role of reason in morality. It suggests that reason plays no substantive role in how we make moral judgments or are motivated to act on them. This paper explores how it is that an empirically oriented philosopher, committed to methodological naturalism, ought to respond to the skeptical challenge presented by this research.

The burgeoning science of ethics has produced a trend toward pessimism. Ordinary moral thought and action, we’re told, are profoundly influenced by arbitrary factors and ultimately driven by unreasoned feelings. This book counters the current orthodoxy on its own terms by carefully engaging with the empirical literature. The resulting view, optimistic rationalism, shows the pervasive role played by reason, and ultimately defuses sweeping debunking arguments in ethics. The science does suggest that moral knowledge and virtue don’t come easily. However, despite the heavy influence of automatic and unconscious processes that have been shaped by evolutionary pressures, we needn’t reject ordinary moral psychology as fundamentally flawed or in need of serious repair. Reason can be corrupted in ethics just as in other domains, but a special pessimism about morality in particular is unwarranted. Moral judgment and motivation are fundamentally rational enterprises not beholden to the passions.

In the present article we demonstrate stable individual differences in the extent to which a reliance on logic and evidence in the formation and evaluation of beliefs is perceived as a moral virtue, and a reliance on less rational processes is perceived as a vice. We refer to this individual difference variable as moralized rationality. Eight studies are reported in which an instrument to measure individual differences in moralized rationality is validated. Results show that the Moralized Rationality Scale (MRS) is internally consistent, and captures something distinct from the personal importance people attach to being rational (Studies 1–3). Furthermore, the MRS has high test-retest reliability (Study 4), is conceptually distinct from frequently used measures of individual differences in moral values, and it is negatively related to common beliefs that are not supported by scientific evidence (Study 5). We further demonstrate that the MRS predicts morally laden reactions, such as a desire for punishment, of people who rely on irrational (vs. rational) ways of forming and evaluating beliefs (Studies 6 and 7). Finally, we show that the MRS uniquely predicts motivation to contribute to a charity that works to prevent the spread of irrational beliefs (Study 8). We conclude that (1) there are stable individual differences in the extent to which people moralize a reliance on rationality in the formation and evaluation of beliefs, (2) that these individual differences do not reduce to the personal importance attached to rationality, and (3) that individual differences in moralized rationality have important motivational and interpersonal consequences.

T he notion of 'intuition' is usually contrasted with rational thought, thus motivating a differentiation between two kinds of processes that are supposed to characterize human thinking, i.e. rational and 'intuitive' (immediate and non-argumentative) forms of judgment. Recently, the notion of intuition has also played a leading role in cognitive studies on morality with the rise of so-called social intuitionism, according to which people's moral stances are culturally driven intuitions -i.e. they are quick, involuntary and automatic responses driven by culturally and socially acquired principles (see e.g.

With the rapid recent growth of naturalized metaethics, Richard Joyce's paper sounds an appropriate cautionary note. It's easy to be overwhelmed by sexy new data and to neglect the difficulties in using the data to draw major philosophical conclusions. One of the central views in the sights of naturalists has been moral rationalism. Jonathan Haidt (2001), Joshua Greene (this volume), Jesse Prinz (forthcoming), and I (2002, 2004b) have all used recent empirical findings to challenge moral rationalist views. Although Joyce is not himself a moral rationalist (see Joyce 2002), he deftly works to beat back our attacks on moral rationalism. Here my goal is to uphold the view that empirical work can challenge moral rationalism in the aftermath of Joyce's insightful discussion.

Ratio

Moral Rationalism is the view that if an act is morally required then it is what there is most reason to do. It is often assumed that the truth of Moral Rationalism is dependent on some version of The Overridingness Thesis, the view that moral reasons override nonmoral reasons. However, as Douglas Portmore has pointed out, the two can come apart; we can accept Moral Rationalism without accepting any version of The Overridingness Thesis. Nevertheless, The Overridingness Thesis serves as one of two possible explanations for Moral Rationalism. In this paper I will investigate which of these two explanations a moral rationalist should accept. I will argue that when we properly attend to the form of Moral Rationalism supported by the intuitions that motivate the view, we are left with no reason to accept The Overridingness Thesis.

Regard for Reason in the Moral Mind argues that a careful examination of the scientific literature reveals a foundational role for reasoning in moral thought and action. Grounding moral psychology in reason then paves the way for a defense of moral knowledge and virtue against a variety of empirical challenges, such as debunking arguments and situationist critiques. The book attempts to provide a corrective to current trends in moral psychology, which celebrate emotion over reason and generate pessimism about the psychological mechanisms underlying commonsense morality. Ultimately, there is rationality in ethics not just despite but in virtue of the neurobiological and evolutionary materials that shape moral cognition and motivation.
