One of the eye-opening claims in Frederique Janssen-Lauret's recent (2022) Cambridge Elements on Susan Stebbing is that "much of Stebbing's published work focussed on the philosophy of science and especially on the philosophy of physics." (32) Accordingly Janssen-Lauret devotes considerable space to Sttebbing’s philosophy of science in her book, especially, Stebbing's famous critique of Eddington, but also -- and I suspect this prepared my mind for what follows -- to the complex relationship between Stebbing's philosophy of science and her distance from Moore's philosophy.
