John Inazu's Learning to Disagree is really several books in one. First, it is a "welcome to law school" book. Second, it is an extended argument on how we might be able to live in a polarized society. Third, it is part autobiography.
As you consider all of those threads, I think the assumption would be that is too much to accomplish in one slim volume. Inazu manages it with aplomb. The book is structured around the typical academic year for law school, with chapters dedicated to each month. While the calendar provides the spine of the work, the bulk is made up of stories drawn from Inazu's years of teaching. The characters are mostly composites, but you read of students (gunners and strugglers), colleagues, people in his church, and his family. Since Inazu himself is really the main character, the book is devoted to how he navigates these relationships.
His life, devoted primarily to teaching and writing about law and religion, is complicated and lends itself to hard questions and conversations. He daily explores the difference between evil and wrong, the values that undergird court decisions and those affected by them, and the difficulty of being gracious to people where they are--even if you think they are sorely mistaken.
What makes Inazu's book compelling is the basic assumption that will challenge many narratives: America is big and divided. We can either understand and influence that reality or seek to destroy, demonize, or ignore those on the "other side." There is nothing too deep or penetrating in the book. It is simple, but that is its strength.
Finally, I will recommend this book to everyone interested in law school, and, maybe, everyone in general.
