This study examines the reception of contractual solidarism in French le- gal doctrine. It highlights two historical periods: the late 19th to early 20th century and the late 20th century revival. The analysis reveals a predomi- nant ideological bias in French legal discourse, characterized by a reluctance to engage with alternative theories and a tendency to uphold existing prin- ciples. This study sheds light on the ideological underpinnings of French legal discourse and its impact on the reception of innovative legal theories.
