In this paper, I focus on Damaris Masham, to re-consider the relationship of her philosophy to the two philosophers with whom she was most closely associated: John Locke, and her father, the Cambridge Platonist, Ralph Cudworth. After considering some of the problems of interpretation which have arisen in scholarly debates, I focus her Occasional Thoughts to highlight continuities with both Locke and Cudworth in her epistemology, moral philosophy and metaphysics. I argue these show that Damaris Masham’s philosophy does not fit the received categories of empiricist or rationalist of the dominant narrative. Her position requires us to reconsider not just the relationship of her philosophy to that of Cudworth and Locke, but also of the relationship of Cudworth and Locke. Ultimately, therefore, reintegrating women into the history of philosophy challenges us to rethink standard narratives of the history of philosophy
