The Foundations of Justice in Jules Dupuit’s Thought
Résumé
The ongoing interpretation of Dupuit’s conflict with the French liberal school on the question of justice consists of a simple opposition between
public utility and natural rights. This paper aims to show that Dupuit’s position is far more complex: justice is based on welfare – and thus on
public utility – although natural rights are not excluded from his scheme.
An understanding of Dupuit’s concept requires a clarification of the differences between three notions – public interest, welfare and public utility – and, by the same token, of the factors linking each notion to the others.
