Mary Shepherd 1777 – 1847

Lady Mary Shepherd was a Scottish philosopher and one of the most acute British metaphysicians of the early nineteenth century. The daughter of an Earl, she received an extensive private education in mathematics, science, and philosophy, and after her marriage and move to London she carried on serious philosophical exchange with figures including William Whewell and Charles Babbage. Her Essay upon the Relation of Cause and Effect and Essays on the Perception of an External Universe defended an a priori principle of causation against Hume's skepticism and a perceptual realism against Berkeleyan idealism. Long neglected, her work has been an important site of the recent recovery of women in early modern philosophy.
