Erich Fromm 
Man for Himself [PDF ebook] 
An Inquiry into the Psychology of Ethics

This is Volume VIII of thirty-eight of collection of works on General Psychology. Initially published in 1947, it offers an enquiry into the psychology of ethics and forms a continuation of the author’s other work 'Escape from Freedom’ in which he attempted to analyse modern man’s escape from himself and his freedom. This book discusses the problem of ethics, of norms and values leading to the realisation of man’s self and of his potential.
