The last guy is right, this book is worth 4 stars. But not because of some seminary stuff: I'll explain henceforth.
1st reason- This book has the failings of a few other Ellul books, most namely to me The Technological Bluff. His ideas are quite fine, but applied too specifically to stuff I don't know or care about. The French Government, this weird medical device that they obviously don't use anymore: personally, I like Ellul's broad, world-encompassing notions and ideas. "Think globally, act locally!" Indeed, Ellul (that's his slogan)!
2nd Reason- because it's similar to Conversations with Patrick Troude-Chastenet... but not as good! Here he also brings back some of his big ideas, and doles out some more really good ones! Yes, I admit that! But it doesn't have the poetic narrative of his own life to feed from. It's more just like "hodge podge of thinkings from the porch of Jacques Ellul." If you haven't read Conversations, read that first. Then this. I still insist it is very good, but some parts... the problem could also be that I'm not into dissecting economic situations, and here he discusses Marxism (and its influence on him) pretty heavily.
The last chapter on religion is good for bridging the gap from Ellul's study of technique to his ideas on religious texts. I was pretty disappointed when I found out he was a Christian, thinking perhaps he was a crackpot who had some moral aversion to the technologically advanced rock n' roll kids are listening to these days (and he does say that at one point), but he does have some very eccentric and thoughtful spiritual ideas that definitely separate him from the herd of followers. Because I dislike blind followers of both religion and technology, so I said, "Oh no, Ellul: don't do dat, boy!" at first. But he's all right, so far as I know. No "God told me to save the world by writing this book" or "the human body is a technology of God, so that's okay!" Enjoy!
