A Dilemma for Dialetheism

I've just published a revised version of my article "A Dilemma for Dialetheism" on Scholardarity.com, which was originally published in the Spring 2010 edition of the Stanford undergraduate philosophy journal The Dualist (vol. 15). In the article I argue that dialetheists, who believe that some sentences are both true and false, either cannot express the notion that some sentences are not both true and false, or else that their accounts suffer from "revenge" liar paradoxes that not even they can regard as being both true and false. If you like logic and paradoxes as much as I do, please check it out and let me know what you think.
