The literature of bioethics suffers from two serious problems. (1) Most authors are unable to take seriously both the rights of the great apes and of severely disabled human infants. Rationalism—moral status rests on rational capacities—wrongly assigns a higher moral status to the great apes than to all severely disabled human infants with less rational capacities than the great apes. Anthropocentrism—moral status depends on membership in the human species—falsely grants all humans a higher moral status than the great apes. Animalism—moral (...) status is dependent on the ability to suffer—mistakenly equates the moral status of humans and most animals. (2) The concept person is widely used for justificatory purposes, but it seems that it cannot play such a role. It seems that it is either redundant or unable to play any justificatory role. I argue that we can solve the second problem by understanding person as a thick evaluative concept. This then enables us to justify assigning a higher moral status to the great apes than to simple animals: the great apes are persons. To solve the first problem, I argue that certain severely disabled infants have a higher moral status than the great apes because they are dependent upon human relationships for their well-being. Only very limited abilities are required for such relationships, and the question who is capable of them must be based on thick evaluative concepts. Thus, it turns out that to make progress in bioethics we must assign thick evaluative concepts a central role. (shrink)

The aim of this paper is to propose a model for understanding the relation between substance and procedure in discourse ethics and deliberative democracy capable of answering the common charge that they involve an ‘empty formalism’. The expressive-elaboration model introduced here answers this concern by arguing that the deliberative practical rationality presupposed by discourse ethics and deliberative democracy involves the creation of a practical medium in which certain general basic ideas of solidarity, equality and freedom are expressed and elaborated in (...) the context of widespread moral disagreement. In the course of this paper I propose an elucidation of these ideas and argue for the thesis that they are internally related to the endorsement of deliberative practical rationality. The three basic substantive ideas contribute to the determination of the existence, the form, the topics and intended outcomes, and the effects of the practice of public deliberation. This amounts to an elucidatory defense of deliberative practical rationality by explicating its substantive significance or point. Key Words: critical theory • deliberative democracy • discourse ethics • equality • freedom • Jürgen Habermas • practical reason • John Rawls • solidarity • substance and procedure. (shrink)

This paper presents a substantivist construal of discourse ethics, which claims that we should see our engagement in public deliberation as expressing and elaborating a substantive commitment to basic moral ideas of solidarity, equality, and freedom. This view is different from Habermas's standard formalist defence of discourse ethics, which attempts to derive the principle of discursive moral justification from primarily non-moral presuppositions of rational argumentation as such. After explicating the difference between the substantivist and the formalist construal, I defend the (...) former by showing that it is not only intuitively compelling, but also particularly well equipped for addressing four important objections recently levelled against discourse ethics and its political applications. I conclude by pointing out some consequences of the previous discussion for the future of Critical Theory. (shrink)

This is a critical discussion of Habermas's conception of moral cognitivism. I explain how it fits in with his meta-ethical anti-realism. I place Habermas's Discourse Ethics in the broad field of analytic meta-ethics. I also look at the question of whether the Frege-Geach problem applies to Habermas's Discourse Ethics, and if so, how he should best reply.
