Catharine Trotter Cockburn (1679–1749) was an English novelist, dramatist, and philosopher whose intellectual contributions spanned literature, theology, and moral philosophy. Active during the late seventeenth and early eighteenth centuries, she established herself as a versatile writer and a keen participant in the philosophical debates of her era. Her work is characterized by a deep engagement with complex metaphysical and ethical questions, including the nature of necessity, substance, and the infinitude of space.\n\nTrotter's primary intellectual focus lay in moral philosophy. She argued against the concept of inherent moral principles, proposing instead that individuals could discover moral truths through the application of reason, which she viewed as a divine gift. Her philosophical acumen was demonstrated in her 1702 publication, A Defence of Mr. Lock's An Essay Concerning Human Understanding. This work defended John Locke's empiricist philosophy and earned her the personal admiration and financial support of Locke himself, who sent her books and funds through an intermediary.\n\nThroughout her career, Trotter maintained a prolific correspondence and attracted the attention of other prominent contemporary figures, including the writer William Warburton, who contributed a preface to her final philosophical work. Toward the end of her life, she collaborated with biographer Thomas Birch to compile her writings, though she passed away before the project was finalized. Birch posthumously published her collected writings in 1751 as The Works of Mrs. Catharine Cockburn, Theological, Moral, Dramatic and Poetical, preserving her legacy for future generations of readers and historians.
