  The Opus postumum has long been a topic of interest especially insofar as it offers the hope of clarification and development of central issues in Kant's Critical philosophy. While much of the original literature focussing on it was in German (Adickes 1920, Hoppe 1969, Tuschling 1971, and, more recently, Blasche, 1991 and Emundts, 2004), it has received increased attention of late in English with discussions by Friedman (1992, chapter 5), Förster (2000), Edwards (2000), Guyer (2001), and Hall (2006, 2009).
