The text is thematically structured, covering the discipline”s principal ideologies: Statism; Realism; Liberalism; Conservatism; Socialism; Anarchism; and Environmentalism. It also offers a brief history of political philosophy and the major political philosophers, including Plato, Aristotle, Locke, Rousseau, Hobbes, Marx and Rawls, and, valuably, concludes with a look at ”applied” political philosophy, relating the discipline to contemporary political situations and questions.
