Toleration as Impartiality? Civil and Ecclesiastical Toleration in Jean Barbeyrac

Jean Barbeyrac is a seminal figure in the history of natural law doctrine and one who, as a Huguenot refugee, had much to say on the topic of toleration. For Barbeyrac, natural law offered a secular rationalist principle of morality that could be used in the battle against Catholic persecution. Barbeyrac took from his seventeenth-century predecessors the natural law idea that the state was an essentially secular body and used that idea to license a much more thoroughgoing form of toleration. If the state had no religious competence then even atheism could be permitted, because it did not constitute an injury to the civil peace. This chapter shows that Barbeyrac's radical account of natural law and toleration made substantial modifications to the arguments of his predecessors, and in doing so moved natural law beyond the theological constraints that structured the defining work in the genre.
