This past Spring Ollie turned me on to psychologist Adam Phillips book of essays titled On Flirtation. A great read, I was unfamiliar with Adam Phillips before picking this up.
BBC Radio is currently presenting a series of essays by Phillips called On Excess. (Hurry up if you want to hear them, each is posted for omly 5 days or so.)
From the site:

1. In Excess
