Ian Hinckfuss' "The Moral Society"

Lately, I've been reading more about contemporary ethical skepticism and Mackie's moral error theory, and have found out that Ian Hinckfuss (who passed away in 1997) defended an interesting version of ethical nihilism in his book The Moral Society: Its Structure and Effects (Canberra: Australian National University, 1987). (The original, cool title of the book was To Hell with Morality.) Although the book is out of print, I've found an online version which incorporates some revisions. To access the file, go here (if you encounter any problem, let me know).
