 Jones addressed the dualism on various occasions throughout her career (Jones 1894, 1894–95, 1895, 1909, 1917–18, 1920), and a full survey of these discussions is not possible here. This section will focus on her most considered response to the dualism, her late publication “Practical Dualism” (Jones 1917–18). Where relevant, I will also quote from her roughly coeval entry on Sidgwick for the Encyclopaedia of Religion and Ethics (Jones 1920).
