Abstract
Henry Sidgwick shared many of the feminist concerns of John Stuart Mill and was an active reformer in the cause of higher education for women, but his feminism has never received the attention it deserves and he has in recent times been criticized for promulgating a masculinist epistemology. This essay is a prolegomenon to a comprehensive account of Sidgwick's feminism, briefly setting out various elements of his views on epistemology, equality, gender, and sexuality in order to provide some initial sense of how he carried on and developed the Millian project
