The problem Professor Dumm and his book suffers from is the need to speak to two different audiences that prove utimately incompatible, the academic and the intelligent, lay public. Professor Dumm is a scholar, a political scientist at Amherst. He wants to be published by an academic, refereed press. So his book must meet whatever methodological and ideological standards that hold sway. Whatever those are right now, abstract, theory-driven writing is required. Hence he spends a lot of time discussig his theory of the Missing Mother, which I do not find at all convincing. Like all academic books, this one is heavily footnoted, and it alludes frequently other scholarly work, as well as to classical literature. It is not a very readable book.
All of this is well and good, but it certainly does not speak very adequately to Professor Dumm's second audience: people who are motivted to read the book, becaue they may be seeking consolation from their loneliness, or they may just be seeking a better understanding of loneliness, whether they are lonely or not. In other words, intelligent, but non-academic people. In my case, though not seeking consolation, I am lonely, and the idea of lonliness as a way of life was intriguing to me. But I was frustrated by Professor Dumm's book, because so little of it seems to speak directly and plainly to exactly its title, loneliness as a way of life. There are parts which I think are intended by Professor Drumm to do that. I have in mind those parts when he goes inward to his reflections about his own loneliness, it's sources, and what he thinks about it. But there are too few of those. And Professor Dumm's writing style is not intimate, though he certainly addresses intimate matters.
But, the book simply is not broad or rich enough to speak adequately to both audiences, the academic and laypeople interested in loneliness; it cannot bear that weight. I don't think a book can be both academic and intimate. The academic crowds out the lay by a wide margin. I realize Professor Dumm may never have expected his book to speak to anyone but an academic audience. But, in that case, Harvard Press, or the blurbs on the dust cover, would have been better off talking about this book's contribution to the academic literature, and not about it's general wisdom on loneliness that is a part of so many peoples' lives.
So read it for its academic content, which, as I say, I don't rate highly. But, I am not an academic. I can't recommend it as a way of understanding better or addressing one's own loneliness.
