She was laughed at by her contemporaries, not taken seriously by philosophical research, but revered by her husband. It is a mix of conflicting feelings that the English philosopher Margaret Cavendish, Duchess of Newcastle, has evoked throughout her life and even after her death. Her own attitude was also ambivalent. Margaret Cavendish repeatedly played new roles, constantly redefining herself. She was the compliant wife who accompanied her husband into exile, but also the emancipated partner who managed the financial affairs. Furthermore, Margaret Cavendish was a visionary philosopher and a scientist who provoked her colleagues. The title "PhilosophinnenLeben: Margaret Cavendish" by Ursula I. Meyer is the second in the format of a narrative biography. The author describes Cavendish's various phases of life.
