The Principles of the Most Ancient and Modern Philosophy

Book excerpt: Anne Conway, Viscountess Conway (1631-1679), nee Finch, was an English philosopher whose work, in the tradition of the Cambridge Platonists, was an influence on Leibniz. She became interested in the Lurianic Kabbalah, and then in Quakerism, to which she converted in 1677. In England at that time the Quakers were generally disliked and feared, and suffered persecution and even imprisonment. Conway's decision to convert, to make her house a centre for Quaker activity, and to proselytise actively was thus particularly bold and courageous. Her life from the age of twelve (when she suffered a period of fever) was marked by the recurrence of severe migraines. These meant that she was often incapacitated by pain, and she spent much time under medical supervision and trying various cures (at one point even having her "jugular arteries" opened). None of the treatments had any effect, and she died in 1679 at the age of forty-seven.
