On the definition of jealousy and other emotions in Anarchy, State and Utopia

This paper responds to an ingenious footnote from Robert Nozick’s book Anarchy, State and Utopia. Using a table of four possible situations, Nozick defines what it is to be jealous, envious, begrudging, spiteful and competitive. I deny a claim that Nozick makes for his table, a claim needed for these definitions. I also point out that Nozick fails to capture what he has in mind by jealousy.
