From a theme that concerns us all: our life successful, Professor Luc Ferry shows us how this issue was at the center of human concerns of all time and how men responded over the centuries by philosophical or religious systems . And we perceive it better most of these doctrines and the complex relationships they have maintained. And this without using technical vocabulary, therefore accessible to all "honnète man" of today. It is a book that, personally, I have long wanted.
