answers this central question through the careful study of political philosophers and economists, from ancient Greece to the twenty-first century. The book does not have an ideological agenda and gives equal voice to thinkers on opposite sides of the political spectrum. This is one of its key merits and a mark of distinction: its willingness to treat stark opponents – Hobbes and Locke, Smith and Marx, Keynes and Hayek, among others – as equally worthy of serious study. In doing so, the book provides students with a very powerful arsenal of ideas about the evolution of the market and also provides a solid introduction to the history of political thought.
