Answer
Yes, many of Margaret Cavendish's works contained themes of ambition and social mobility. For example, her 1666 play The Blazing World depicts a female protagonist who achieves social mobility through her own ambition and intellect. Additionally, Cavendish's autobiography, The Life of the Thrice Noble, High and Puissant Princesse, Marchioness of Newcastle, describes her own rise from humble beginnings to a position of power and influence.
