Summary

British philosopher and playwright who was one of the earliest public defenders of Locke's epistemology and developed an account of moral obligation grounded in reason and the nature of things.

Core Contribution

Defended Locke's Essay against critics and developed a rationalist moral philosophy: moral obligations derive from the nature of things and relations, discoverable by reason — anticipating Clarke's rationalist ethics.

Key Spikes & Highlights

Began writing philosophical defenses of Locke at age 22, earning Locke's personal thanks — one of the few philosophers in history to be personally thanked by the thinker they defended.
Converted from Anglicanism to Catholicism at 25, then back again at 42 — philosophical and theological convictions tracked by her denominational migrations.
