Rational Decisions (Princeton 2008). A wide-ranging exploration of standard theories of choice and belief under risk and uncertainty. Binmore argues, in a way accessible to readers who are not mathematically inclined, that the standard Bayesian approach to knowledge is inadequate; and he offers an extension to that theory based on what he calls "muddled strategies" in strategic interactions. Fascinating stuff.
Herzog (Viking 1964). I am re-reading this epistolary novel, one of the great achievements in 20th-century American literature. That I am re-reading Bellow, rather than reading something new, should not be taken as a commentary on the state of American literature today. I just had a hankering for Bellow. Enough said.
