Talk of coherence in ethics is popular. Particularly when dealing with the justification of ethical judgments, one frequently refers back to a concept of coherence. However, the question as to the exact meaning of the term coherence is seldom posed. This book provides a comprehensive answer.

The author shows that there is not a single concept of coherence in ethics. Rather, the word coherence is used to refer to many different concepts that neither can be reduced to one another nor imbedded in a single unified coherence theory.
