As his column today reveals, even the New York Times’s David Brooks is reading this month’s discussion at Cato Unbound on the future of libertarianism.

Today is the last day of the discussion, so don’t miss out! In today’s edition, Cato’s Brink Lindsey discusses “Post-Apocalyptic Libertarianism“ and Virginia Postrel talks about “The Libertarian Cultural Tradition” [.mp3] in the Cato Daily Podcast. Don’t miss Postrel’s thoughts yesterday on ”What Was Wrong with Socialism?” and “Principles, the Welfare State, and Libertarian Cultural Traditions,” or Tyler Cowen’s pithy “Quick Hits” from Tuesday. Tom Palmer promises to chime in before the clock runs out, so don’t stop hitting refresh.

In April, Cato Unbound will tackle the science, culture, and politics of happiness with a mostly stellar lineup featuring historian Darrin McMahon, author of the Happiness: A History; psychologist Barry Schwartz, author of The Paradox of Choice: Why More Is Less; sociologist Ruut Veenhoven, editor of the Journal of Happiness Studies; and, well… me, author of a soon-to-be-released Cato Policy Analysis on the reliability and policy implications of the new “happiness research.”
