Writing in the 1998 edition of the "Routledge Encyclopedia of Philosophy", political theorist Chandran Kukathas summarizes the mainstream philosophical reception to her work in two parts. Her ethical argument, he says, is viewed by most commentators as an unconvincing variant of Aristotle's ethics. Her political theory, he says, "is of little interest", marred by an "ill-thought out and unsystematic" effort to reconcile her hostility to the state with her rejection of anarchism. Libertarian philosopher Michael Huemer argues that very few people find Rand's ideas convincing, especially her ethics, which he believes are difficult to interpret and may lack logical coherence. He attributes the attention she receives to her being a "compelling writer", especially as a novelist, noting that "Atlas Shrugged" outsells Rand's non-fiction works as well as the works of other philosophers of classical liberalism such as Ludwig von Mises, Friedrich Hayek, or Frederic Bastiat.
