Sebastian Junger describes in the "Tribe: On Homecoming and Belonging" a very urgent and relevant cultural themes of our decade. It is all about the bereavement of solitary congregations. It is not he alone speaks about that problem. For example, you can read the most significant work of Robert Putnam. If you do not know about him, please, read the Bowling Alone book.
So Sebastian Junger is not original, but why he is so important? The first reason is that his theory, the book and the language of it are infinitely affordable. But the second reason is more interesting. The author makes his insights from a unique point of view. It formed by his soldierly experience. So, the main thought of the new Sebastian Junger's book is about soldiers' experience. At the war, many people feel a big amount of mutual dependence, unity, and fraternity. So, when they came back home it is very hard for them to find another community in which they can feel the same cohesion.
"Tribe: On Homecoming and Belonging" is the important book about civil life in the USA. The sometime author praises the Indian experience of life in the tribe. He makes an assumption that we must use this experience if we want to build a better society. Do we must. Read this book and make a conclusion by yourself.
