Chapter IV of my dissertation, on the publicity condition, forms the basis for much of my article “Rejecting the Publicity Condition: The Inevitability of Esoteric Morality,” published in The Philosophical Quarterly vol. 63, no. 250 (January 2013), pp. 29–57. A link to this article is on the “Publications” page of my web site.
