This volume illustrates the way political and social philosophers of 18th-century Scotland tried to answer the following question: 'What is, and what ought to be, the relationship between the modern market and stable, desirable social order?' The essays belong to the second half of the century and offer a snapshot of the achievements of Scots on political and social philosophy. The Scottish Enlightenment witnessed the birth of modern social sciences. Its moral philosophers attempted to harmonize a modern market economy with ethics, social order, stable polity and the moral progress of the human race. Their very diversity, and the thoroughness and sincerity of their endeavours, make the works of Scottish philosophers relevant to peoples' lives on every part of the earth in an age of globalization.
