 Reid and Hume both owed an immense debt to Hutcheson. So also did Adam Smith (1723–1790) who, unlike the others, studied under Hutcheson at Glasgow University. In 1751 Smith was appointed to the chair of logic and rhetoric at Glasgow and the following year transferred to the chair of moral philosophy that Hutcheson had occupied. Smith’s An Inquiry into the Nature and Causes of the Wealth of Nations appeared in 1776. Essays on Philosophical Subjects appeared posthumously in 1795. He also published an essay on the first formation of languages, and student notes of his lectures on rhetoric and belles lettres, and on jurisprudence have survived. But much his most important work in philosophy is the Theory of Moral Sentiments which appeared in 1759 and of which six authorised editions appeared during Smith’s lifetime. The second and sixth editions contain significant revisions and additions. Smith sets out to provide a theory that will address the weaknesses of existing systems of moral philosophy (critcised in Part VII of the Moral Sentiments). He does so by rejecting attempts to reduce morality to a single principle and instead seeks to provide an account of the operation of ordinary moral judgment that recognises the central role of socialisation.
