Gray has written several influential books, including False Dawn: The Delusions of Global Capitalism (1998), which argues that free market globalization is an unstable Enlightenment project currently in the process of disintegration; Straw Dogs: Thoughts on Humans and Other Animals (2003), which attacks philosophical humanism, a worldview which Gray sees as originating in religions; and Black Mass: Apocalyptic Religion and the Death of Utopia (2007), a critique of utopian thinking in the modern world.
