Adam Smith and Alexis de Tocqueville dealt with the division of labour as a characteristic feature of commercial society. There are connections and similarities between the two-sided understanding they both had of the division of labour.

Exploring this coincidence brings light to their understanding of the social consequences of the market and the possible solutions they propose.
