How do the students in our classrooms today make sense or nonsense out of sex? This nine paragraph essay, “Sex and Tradition” by Peter Leithart, sets out a polemic for which they will need a little background and assistance to sort out. But a session or two will enable them to consider this theme’s cultural lines of demarcation to see if they agree. The book that Leithart references is The Crisis of Modernity by Augusto Del Noce (McGill Univ Press, 2015).
