Teaching courses originally intended for Dr. Donald A. Nielsen, who retired last year from the Department of Sociology at the State University College of New York (SUNY) at Oneonta, I recently found the brief note “I miss Dr. Nielsen!” among the student evaluations of my “Ideas and Ideologies” class offered during the Fall 2002 semester. Paradoxically, the note also reminded me that I actually miss him too, despite the brief period of our face-toface interactions towards the end of his tenure. Thankfully, just before leaving Oneonta, and having warmly received the first issue of Human Architecture, Dr. Nielsen had kindly agreed to submit one of his own earlier articles on Mannheim to this journal.
