Paul Moreno, the Grewcock Chair in Constitutional History at Hillsdale College, sets out to explain how the natural rights constitutionalism of the Founders was replaced by an ‘entitlement-based welfare state of modern liberalism’ by the late 1930s. The book is an ‘analytic narrative’, drawing on both constitutional theory and current ‘public choice’ law and economics, and contributes to recent scholarship by libertarian-minded legal scholars, such as David Bernstein and David Mayer, among others.
