Postconventional Moral Thinking [PDF ebook] 
A Neo-kohlbergian Approach

Although Lawrence Kohlberg provided major ideas for psychological research in morality for decades, today some critics regard his work as outmoded, beyond repair, and too faulty for anybody to take seriously. These critics suggest that research would advance more profitably by taking a different approach.
Postconventional Moral Thinking acknowledges particular philosophical and psychological problems with Kohlberg»s theory and methodology, and proposes a reformulation called ‘Neo-Kohlbergian.’ Hundreds of researchers have reported a large body of findings after having employed Kohlberg»s theory and methods to the Defining Issues Test (DIT), therefore attesting to the relevance of his ideas.
This book provides a coherent theoretical overview for hundreds of studies that have used the DIT. The authors propose reformulations in the underlying psychological and philosophical theories. This book pulls together the analysis of criticisms of a Kohlbergian approach, a rationale for DIT research, and new theoretical ideas and new research.
