Query: Not very enlightening.

I picked up this book for the history-of-marriage value instead of the same-sex-marriage-propaganda value, and found the history and debated "reasons why people have historically married" to be rather uninformative. A lot of what was said seemed common knowledge about basic history of society. Marriage concepts are talked about generally more often than not. I would have liked to see more hard core facts rather than musings and contemplations. I was hoping for statistics to be sprinkled liberally, and perhaps many tales of certain marriages in the past that stood out either as especially abnormal for a time period, or exceedingly typical.
