Karl Marx quoted Ferguson approvingly and declared that he had been inspired by the latter's insights. But Smith too made some extremely negative and apparently pessimistic observations about the division of labour, giving rise to suggestions that his comments also 'constitute a major source of inspiration for the socialist critique' of commercialism. This article compares and contrasts the respective approaches of the two Scots. It also pays particular attention to claims that there are parallels with Marx in their thinking. To what extent is this true? Further, if it is true, do they anticipate him in the same way?KEYWORDS alienation, division of labour, Durkheim, Ferguson, inequality, Smith, Spencer, Marx, workThe division of labour, 1 and its social and economic effects, has long been an important theme in the history of economic and sociological thought. In this article I highlight and contrast the work of thinkers whose contributions exerted considerable influence over subsequent elaborators of the concept. Though Adam Smith (1723-90) and Adam Ferguson (1723-1816) were neither the first nor last to discuss the effects of the division of labour, 2 it would not be an exaggeration to
