Anne Conway (also known as Viscountess Conway; née Finch; 14 December 1631 – 23 February 1679) was an English philosopher whose work, in the tradition of the Cambridge Platonists, was an influence on Gottfried Leibniz. Conway's thought is a deeply original form of rationalist philosophy, with hallmarks of gynocentric concerns and patterns that lead some to think of it as unique among seventeenth-century systems. Biography Anne Finch was born to Sir Heneage Finch (who had held the posts of the Recorder of London and Speaker of the House of Commons under Charles I) and his second wife, Elizabeth (daughter of William Cradock of Staffordshire).

Her husband was also interested in philosophy and had himself been tutored by More, but she went far beyond him in both the depth of her thought and the variety of her interests. She became interested in the Lurianic Kabbalah, and then in Quakerism, to which she converted in 1677.
