Adam Smith (1723–1790) was the Scottish moral philosopher whose two principal works were The Theory of Moral Sentiments (1st ed. 1759, 6th ed. 1790) and The Wealth of Nations (1st ed. 1776). As a student at Glasgow he studied under “the never to be forgotten” Francis Hutcheson, and later in life he was best friend to the “never to be forgotten” David Hume.
