Although Adam Smith is best known as the founder of scientific economics and an early proponent of the modern market economy, political economy is only one part of his comprehensive intellectual system. Consisting of a theory of mind and its functions in language, arts, science and social intercourse, Smith's system was a towering contribution to the Scottish Enlightenment. This Companion provides an up-to-date examination of all aspects of Smith's thought. Collectively, the essays take into account his multiple contexts--Scottish, British, European, Atlantic, biographical, institutional, political and philosophical.
