Abstract:When people reason on the basis of moral rules, do they suppose that in the absence of a prohibitory rule they are free to act, or do they suppose that morality always requires a justification establishing a permission to act? In this essay we present a series of learning experiments that indicate when learners tend to close their system on the basis of natural liberty and when on the principle of residual prohibition. Those who are taught prohibitory rules tend to (...) infer natural liberty while those taught permission rules tend to infer residual prohibition. In mixed cases, where learners are taught both types of rules, there is some tendency to suppose that natural liberty is the default. Both natural liberty and its denial can be learned; is there a reason to adopt one system of moral rules or the other? We argue that systems of social morality based on a principle of natural liberty have a striking advantage over their competitors: they are well adapted to effectively exploring the constant novel circumstances that arise in open, dynamic, societies.

Since it appeared in 1971, John Rawls's A Theory of Justice has become a classic. The author has now revised the original edition to clear up a number of difficulties he and others have found in the original book. Rawls aims to express an essential part of the common core of the democratic tradition--justice as fairness--and to provide an alternative to utilitarianism, which had dominated the Anglo-Saxon tradition of political thought since the nineteenth century. Rawls substitutes the ideal of the (...) social contract as a more satisfactory account of the basic rights and liberties of citizens as free and equal persons. "Each person," writes Rawls, "possesses an inviolability founded on justice that even the welfare of society as a whole cannot override." Advancing the ideas of Rousseau, Kant, Emerson, and Lincoln, Rawls's theory is as powerful today as it was when first published. (shrink)

Inspired by the success of generative linguistics and transformational grammar, proponents of the linguistic analogy (LA) in moral psychology hypothesize that careful attention to folk-moral judgments is likely to reveal a small set of implicit rules and structures responsible for the ubiquitous and apparently unbounded capacity for making moral judgments. As a theoretical hypothesis, LA thus requires a rich description of the computational structures that underlie mature moral judgments, an account of the acquisition and development of these structures, and an (...) analysis of those components of the moral system that are uniquely human and uniquely moral. In this paper we present the theoretical motivations for adopting LA in the study of moral cognition: (a) the distinction between competence and performance, (b) poverty of stimulus considerations, and (c) adopting the computational level as the proper level of analysis for the empirical study of moral judgment. With these motivations in hand, we review recent empirical findings that have been inspired by LA and which provide evidence for at least two predictions of LA: (a) the computational processes responsible for folk-moral judgment operate over structured representations of actions and events, as well as coding for features of agency and outcomes; and (b) folk-moral judgments are the output of a dedicated moral faculty and are largely immune to the effects of context. In addition, we highlight the complexity of the interfaces between the moral faculty and other cognitive systems external to it (e.g., number systems). We conclude by reviewing the potential utility of the theoretical and empirical tools of LA for future research in moral psychology. (shrink)

Gerald Gaus has written a stimulating and thoroughly argued book. His main aim is to show that the kind of liberalism that is underwritten by the ideal of public reasoning and justification is compatible with the extensive facts of disagreement that we see in contemporary societies regarding justice and politics. Gaus argues that the liberalisms of Rawls and Larmore suffer from the fact that they rely on something quite close to actual consensus on political principles in society. They either end (...) up publicly justifying nothing at all or they end up justifying illiberal conclusions. This is a common complaint and the attempt to show that public justification liberalism can be given an account that avoids these problems is a worthy one. (shrink)

This first volume in the four-volume series The Moral Limits of the Criminal Law focuses on the "harm principle," the commonsense view that prevention of harm to persons other than the perpetrator is a legitimate purpose of criminal legislation. Feinberg presents a detailed analysis of the concept and definition of harm and applies it to a host of practical and theoretical issues, showing how the harm principle must be interpreted if it is to be a plausible guide to the lawmaker.
