Best known for his revolutionary free-market economics treatise The Wealth of Nations, Adam Smith was first and foremost a moral philosopher. In his first book, The Theory of Moral Sentiments, he investigated the flip side of economic self-interest: the interest of the greater good. Smith's classic work advances ideas about conscience, moral judgement and virtue that have taken on renewed importance in business and politics.
In January 1946, the Penguin Classics list was launched with E. V. Rieu's translation of The Odyssey. The series now consists of over 800 titles including the best in English, American, European, classical and non-western literature and an extensive range of philosophy, religion, art, history and politics titles.
