Good connoisseur of the work of J. Ellul, I admit that I had not read when he was released. Yet it is one of his most penetrating books, which he delivers in the most honest and stripped the foundations of his thought without avoiding contradictions, and whose fate is dazzled ... perhaps at the cost of difficulties understanding if you do not read other major works of the author. Perhaps you he donnrera want to go digging Systems Engineer or his masterful ethics of freedom ... This is a must for all those who want to understand one of the great French thinker of the twentieth century, including the timeliness and relevance do not deny for 50 years.
