In this paper, I examine David Lewisʼ treatment of vagueness as a problem of “semantic indecision” and conclude that this position on vagueness is inconsistent with the metaphysics of his theory of modal realism. To reach this, I employ a thought experiment in which an exact counterpart of Lewis is subjected to a series of possible worlds treatments designed to satisfy Lewisʼ criteria for counterparthood and test the limits of semantic treatments of higher-order vagueness. I find that Lewisʼ suggestions for dealing with vagueness fails to pick out counterparts at several points in this series, even when given a satisfactorily precisified set of criteria for the qua relation.]]> http://www.prometheus-journal.com/2009/12/de-re-modality-and-lewis%ca%bc-modal-realism-the-case-for-vague-objects/ http://www.prometheus-journal.com/2009/12/aesthetic-futurity/ http://www.prometheus-journal.com/2009/12/heidegger%e2%80%99s-secular-fall/ http://www.prometheus-journal.com/2009/12/philosophical-opposition-of-liberty-and-utility/ http://www.prometheus-journal.com/2009/12/knowing-nolij/ By Cuong Q.

Last semester I posted a riddle regarded by a number of contemporary philosophers as the "hardest" logic puzzle in the world. Raymond Smullyan, a prominent logician and philosopher, has a number of logic puzzles available online for people to solve, and this particular puzzle received a lot of attention from our readers. After some considerable delay, here is both my solution and various other solutions to the puzzle. Enjoy!
