Chapter 2 discusses the adaptations that Grouchy made to her initial draft of the Letters on Symapthy between 1786 and 1789. It explores her interest, during this period, in the affair of the trois roués, a court case that had captured the attention of her uncle Dupaty and Condorcet. This constituted her first sustained exposure to the political injustices of ancien régime. By engaging with the work of these two men, and the ideas of other eighteenth-century natural rights thinkers, Grouchy developed her own ideas as to how injustice could be combatted. This resulted in various additions to the Letters. Building on her original ideas about sympathy-based morality, she elaborated her own definition of natural rights. She went on to argue that these rights, and justice as a whole, could only exist in society when a minimal degree of social and economic equality was guaranteed by the state. This Chapter argues that this was the period when the Letters changed from a moral treatise to a text concerned with political theory.
