E. E. Constance Jones (1848–1922) was Mistress of Girton College, the newly established women's college at Cambridge University, from 1903–1916. She published widely in philosophical logic and in ethics and moral psychology and was an active member of the British philosophical community from 1890 until her retirement. Her contributions to philosophical logic were wide-ranging and sophisticated, anticipating, if only in outline, celebrated insights of later twentieth-century philosophy of language and logic. In ethics, her writings on hedonism and practical reason were original and innovative and merit further examination.
