In the book under review, Walter Reese-Schafer provides a concise Introduction to the sources, themes and conclusions of the philosophy of Karl-Otto Apel, Emeritus Professor at Frankfurt and close colleague of Jurgen Habermas. There are both Kantian and Peircean themes in Apel, with the chief focus on the concept of discourse ethics.

Ethical disputes arise over differences in the content of the ethical beliefs people hold on either side of an issue. One person may believe that it is wrong to have an abortion for financial reasons, whereas another may believe it to be permissible. But, the magnitude and difficulty of such disputes may also depend on other properties of the ethical beliefs in question—in particular, how objective they are perceived to be. As a psychological property of moral belief, objectivity is relatively (...) unexplored, and we argue that it merits more attention. We review recent psychological evidence which demonstrates that individuals differ in the extent to which they perceive ethical beliefs to be objective, that some ethical beliefs are perceived to be more objective than others, and that both these sources of variance are somewhat systematic. This evidence also shows that differences in perceptions of objectivity underpin quite different psychological reactions to ethical disagreement. Apart from reviewing this evidence, our aim in this paper is to draw attention to unanswered psychological questions about moral objectivity, and to discuss the relevance of moral objectivity to two issues of public policy.

It is now generally understood that constraints play an important role in commonsense moral thinking and generally accepted that they cannot be accommodated by ordinary, traditional consequentialism. Some have seen this as the most conclusive evidence that consequentialism is hopelessly wrong,1 while others have seen it as the most conclusive evidence that moral common sense is hopelessly paradoxical.2 Fortunately, or so it is widely thought, in the last twenty-five years a new research program, that of Agent-Relative Teleology, has come to (...) the rescue on all sides. While consequentialism says that every agent ought always to do that action that will bring about the most good, according to Agent- Relative Teleology. (shrink)

The paper investigates different ways to understand the claim that non-cognitivist theories of morality are incoherent. According to the claim, this is so because, on one theory of truth, non-cognitivists are not able to deny objective truth to moral judgments without taking a substantive normative position. I argue that emotivism is not self-defeating in this way. The charge of incoherence actually only amounts to a claim that emotivism is incompatible with deflationary truth, but this claim is based upon a mistake. (...) It relies upon a problematic understanding of both emotivism and the deflationary theory of truth. (shrink)

So-called "thick" moral concepts are distinctive in that they somehow "hold together" evaluation and description. But how? This paper argues against the standard view that the evaluative contents of thick concepts belong to their semantically expressed meaning or sense. It cannot explain linguistic data concerning how thick concepts behave in a distinctive type of disagreements and denials which arise when one speaker regards another's thick concept as "objectionable" in a certain sense. The paper also briefly considers contextualist, presuppositional, and implicature (...) accounts of the evaluative contents of thick concepts, but finds none clearly superior to the others. (shrink)
