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.

Pleasure is one of the strongest candidates for an occurrence that might be good, in some respect, unconditionally. Malicious pleasure is one of the most often cited alleged counter-examples to pleasure’s being an unconditional good. Correctly evaluating malicious pleasure is more complex than people realize. I defend pleasure’s unconditionally good status from critics of malicious pleasure.
