Tribe is not just a book about PTSD, it is a serious reflection on the dominant culture in American society. Sebastian Junger lays out, in detail, an argument that American culture has wandered so far from our tribal roots that we can’t offer a meaningful experience of connection and community to returning veterans that rivals what they experience in war. We can’t offer it because we’re not living it. If you love someone who went to war and came home, this will likely speak to you (reading Tribe helped me come to a deeper understanding of my ex-Marine father). If you don’t have any veterans in your circle, even more reason to educate yourself.
