As noted on my Personal Choice page, Derek Parfit’s Reasons and Persons is a book that has a particular resonance for me, as indeed it does for many people. Thanks to a link in Parfit’s Wikipedia page I found this detailed biograhical article, How to Be Good, from the New Yorker. You can download or print it for free and it’s excellent, so I’m linking to it here for anyone who shares my fascination with this extraordinary philosopher.
