Works & Achievements

Years of philosophical letter-exchanges that served both as her education and as a major testament to her thought in the making.
She conceives of the universe as a set of living, interconnected entities, rejecting Descartes's sharp separation between body and mind. This idea foreshadows Leibniz's monads.

Anecdotes
Anne Conway suffered all her life from atrocious, incurable migraines. The greatest physicians of her time, including the famous William Harvey who discovered blood circulation, tried to cure her, in vain. Yet it was in pain and confined to her bed that she developed an entire philosophy.
As a woman in the 17th century, she was not allowed to study at the universities of Oxford or Cambridge. She therefore taught herself, corresponding for years with the philosopher Henry More of Cambridge, who became her teacher and then regarded her as his intellectual equal.
Her only book was published posthumously, nine years after her death, and first in Latin. It had been found in the form of notes in her notebooks, then translated and printed without her name clearly appearing on it at first.
Toward the end of her life, Anne Conway joined the Quaker movement, a bold and frowned-upon decision since they were being persecuted in England at the time. She welcomed imprisoned and freed Quakers into her home.
When she died, her husband had her body preserved in a coffin filled with spirits (alcohol) and fitted with a glass pane, so that he could see her one last time upon his return from his journey.
