This is a study about the possible legitimacy of studying Jean Jacques Rousseau and his theory of the confession from a philosophical perspective, and from an Arab perspective. In terms of the former, it is a study of the legitimacy of studying the theory of the confession and its connection with the theory of justice, on its own philosophical terms. When it comes to the Arab perspective, legitimacy means the existence of formulations, ideational or realist, theoretical or practical, at least partially and relatively reasonable and acceptable, that reveal the possibility of undertaking some study and the necessity of undertaking it.
