Anne Conway

Also known as Viscountess Conway

RationalistEarly Modern

Born 1631 CE

Died 1679 CE

She argued that spirit and matter are not two things but one, and quietly shaped Leibniz's monads.

Largely self-taught and often bedridden by relentless headaches, Anne Conway thought her way to a bold monism in a single posthumously published book. There are not two substances, mind and matter, she argued, but one living substance shading by degrees from densest body to purest spirit, every creature capable of rising toward the good. She rejected the cold mechanism of Descartes and Hobbes for a universe alive throughout. Leibniz read her work and adopted her term, the monad, carrying her vision of living, perceiving units into the center of modern philosophy.

Anne Conway writes monist philosophy in London sickroom, spirit and matter as one living substance shading upward.
One substance, many degrees.

Influence

Influenced by

  • Descartesdualism rejected outright

    Conway argued that mind and body cannot be two substances, since what has nothing in common can neither act nor be acted on, and proposed instead a single created nature that ranges from grosser to subtler forms of one living stuff.

  • Spinozanamed and opposed

    Conway discusses Spinoza directly and rejects him, refusing to collapse God and creation into one substance while still insisting that everything created shares a single nature.

Influenced
