 Fried took on these arguments directly, and the corpus of work that sprang from the book greatly enlarged the debate. In 2012 a special conference and subsequent issue of the Suffolk University Law Review revisited Fried’s work, 30 years on. This new corpus of work provides us with some interesting new explorations. As an example of this, see Brian Bix’s assessment in his essay (2012). Subsequent to this Fried released an updated version of the book in 2015, which in turn has spawned a more recent literature (see Markovits 2020; Saprai 2013; Bix 2017; Encarnacion 2018)
