Like so many who have survived American post-graduate education in philosophy, I entered the academy having neither formal training in teaching nor writing. (Oh, as I see it, taking a few college courses on composition and literature does not count as a means to avoiding dull prose.) I became a teacher by imitating my professors and through trial and error; I developed as a scholar, and only secondarily as a writer, through countless comments given to me during seminars and office visits, as well as in the margins of my papers. Yes, marginalia, the holy grail of insight!
