Kant’s Impure Ethics [PDF ebook] 
From Rational Beings to Human Beings

This is the first book-length study in any language to examine in detail and critically assess the second part of Kant’s ethics—an empirical, impure part, which determines how best to apply pure principles to the human situation. Drawing attention to Kant’s under-explored impure ethics, this revealing investigation refutes the common and long-standing misperception that Kants ethics advocates empty formalism. Making detailed use of a variety of Kantian texts never before translated into English, author Robert B. Louden reassesses the strengths and weaknesses of Kantian ethics as a whole, once the second part is re-admitted to its rightful place within Kant’s practical philosophy.
