This critical exposition of Adam Smithâs Theory of Moral Sentiments, first published in 1971, gives an appreciation of Smithâs conception of scientific method as applied to the study of social phenomena. The work is placed in the context of Smithâs other writings including of course The Wealth of Nations, but making special use of the theory of scientific development contained in his posthumous work, Essays on Philosophical Subjects. By concentrating on Smithâs methodological approach to the study of society, this book provides an illuminating interpretation of his moral theory and defends it against any mistaken criticisms. It also includes a much needed analysis of the important differences between Smithâs âimpartial spectatorâ and the âideal observerâ of modern ethical society. The result is a pointed study, bringing out the close connection between his moral, legal and ethical theories, which will be welcomed by all students of 18th century thought, specialists in moral theory, and the interested lay-reader.
