Alfred Ewing 
Second Thoughts in Moral Philosophy (Routledge Revivals) [PDF ebook] 

First published in 1959, this volume follows on from Dr. A. C. Ewing’s earlier work, The Definition of Good. The book does not apologize or undermine Ewing’s previous publication but after further consideration on the topic, it explores the issues that were arguably overlooked in the original book. For example, it looks at the possibility of intermediate positions which have been developed since the philosophers Moore and Ross did their main work. Ewing also responds to the criticisms that originated from The Definition of Good and suggests that Secondary Thoughts in Moral Philosophy makes his reading on the topic more balanced.
