Just published a book on Humor and the Good Life in Modern Philosophy: Shaftesbury, Hamann, Kierkegaard (Albany, NY: SUNY Press, 2014) (see http://www.sunypress.edu/p-5779-humor-and-the-good-life-in-mode.aspx). I am finishing another monograph on Laughter in the Good Life: Montaigne, Nietzsche, Santayana, to be published also by SUNY Press.
