Published originally in 1975, The Limits of Liberty made James Buchanan’s name more widely known than ever before among political philosophers and theorists and established Buchanan, along with John Rawls and Robert Nozick, as one of the three new contractarians, standing on the shoulders of Hobbes, Locke, and Kant. While The Limits of Liberty is strongly related to Buchanan’s Calculus of Consent , it is logically prior to the Calculus, according to Helmut Kliemt in the foreword, even though it was published later. Buchanan frames the central idea most cogently in the opening of his preface: Precepts for living together are not going to be handed down from on high. Men must use their own intelligence in imposing order on chaos, intelligence not in scientific problem-solving but in the more difficult sense of finding and maintaining agreement among themselves. Anarchy is ideal for ideal men; passionate men must be reasonable. Like so many men have done before me, I examine the bases for a society of men and women who want to be free but who recognise the inherent limits that social interdependence places on them .
