On April 18, 2009, the Platypus Affiliated Society conducted the following panel discussion at the Left Forum Conference at Pace University in New York City. The panel was organized around four significant moments in the progressive separation of theory and practice over the course of the 20th century: 2001 (Spencer A. Leonard), 1968 (Atiya Khan), 1933 (Richard Rubin), and 1917 (Chris Cutrone). The following is an edited transcript of the introduction to the panel by Benjamin Blumberg, the panelists’ prepared statements, and the Q&A session that followed.
