 Another point of criticism Bastiat raised was that living purely in nature would doom mankind to suffer unnecessary hardships.The Marquis de Sade's "Justine, or the Misfortunes of Virtue" (1791) partially parodied and used as inspiration Rousseau's sociological and political concepts in the "Discourse on Inequality" and "The Social Contract".Concepts such as the state of nature, civilization being the catalyst for corruption and evil, and humans "signing" a contract to mutually give up freedoms for the protection of rights, particularly referenced.
