My book of the year is Eric Anderson’s The Monogamy Gap: Men, Love, and the Reality of Cheating (OUP, 2012). According to Anderson, moral and cultural expectations of strict monogamy are psychologically unrealistic, pervasively and deeply harmful, and (ironically enough) destructive of good relationships. He argues that the phenomenon of widespread “cheating” is the corollary of a system that is incompatible with human psychology and appears ridiculous when viewed from outside its assumptions. Far more research is needed, as the author acknowledges, but meanwhile he presents a lucid and persuasive, if incomplete, case against the ideology of strict monogamy.
Speaking of strict, my strictly philosophy book of the year will be announced in a forthcoming issue of The Philosophers' Magazine. If you don't subscribe, you should do so.
As for fiction, I read some great material by Alison Goodman, Margo Lanagan, and many others. I'm one of the judges of the Norma K. Hemming Award, so I'm expecting to read a lot of high quality fantasy, science fiction, and horror over the next few months. Doubtless I'll be blogging about some of it.
