In April 1972, the year after I lost my wife, I returned to Kyoto University via London. At the University, the students had gone on a lengthy strike to protest the dismissal by the Faculty of Economics of a radical instructor named Nobuhiro Takemoto, who had gone underground and hadn’t appeared on campus. As I was at the Institute of Economic Research, I didn’t have lecture duties, but acceding to the wishes of students, I volunteered to give an unofficial seminar (Fig. 20.1). One of the attendees was Mitsuhiro Fukao, an engineering student, who later became a noted economist.
