Thanks to Andy Clarkson of the Charlotte Capitalist for recommending Wilhelm Windelband's book, History of Philosophy.
I have picked Ayn Rand Answers by Robert Mayhew as this Book of the Month. I look forward to attend Robert Mayhew's lecture, Humor in The Fountainhead, at the Objectivist conference in London. If you haven't purchased August's book yet, read Robert Tracinski's review of the Capitalist Manifesto: The Historic, Economic and Philosophic Case for Laissez-Faire.
I have added Robin Field's online store Classic Readings to the Literature category. [Hat tip to Betsy Speicher's CyberNet.] I have to purchase Reason in Rhyme: A Musical Introduction to Philosophy sometime in the future.
