 Further Reading. Chapter 2 of Ryckman (2005) provides a very clear attempt at reconstructing Reichenbach’s struggle with Kantian principles in the 1920s. Padovani (2008) provides a wealth of textual detail and references for the same period, with a more focused notion of Reichenbach’s notion of “coordination” in Padovani (2011, 2015, 2017). Chapter 6 of Milmed (1961) traces the Kantian elements in Reichenbach’s epistemology and discusses the conflicts that arise, though the analysis concerns primarily Reichenbach’s mature views.
