Abstract

Smith's two‐year tour abroad with young Buccleuch was modest rather than ‘grand,’ but allowed him to investigate a range of regional economies and two unfamiliar political systems: France's autocracy and republican oligarchy in Switzerland. France's taxation problems in the aftermath of war were of particular interest to him, a topic found in WN. Most of his time was spent in Toulouse, when Voltaire was leading a successful fight for a posthumous retrial there of Jean Calas, a victim of religious bigotry and miscarriage of justice. Smith later visited Voltaire, who was his intellectual hero, at his home, Ferney, near Geneva. When in Paris, Smith was introduced to leading philosophes, who were impressed by TMS, also to Turgot and Quesnay, whose Physiocratic views on circular flow in the economy persuaded him to make adjustments in his system.
