Guided by the feminist intention of reasserting the importance of neglected female writers, I have used this work to re-examine the lives and texts of eighteenth-century diarists Hester Thrale-Piozzi and Frances Burney. Adopting an interdisciplinary methodology, I draw on both literary and non-literary material to examine the effect of familial and social patriarchy in eighteenth-century England. Using the diaries, journals and letters of Hester and Frances, I ask why female conformity to masculine domination was expected, and how violence was used to extract subserviant behaviour from women. Beginning with gossip, and encompassing social, editorial and physical abuse, I use the medical profession's manipulation of female vulnerability to exemplify the way society legitimates violence to ensure female ductility. Moving beyond this physical aspect, I then examine the psychical, and question the existence of a ‘self’ which is vulnerable to external manipulation. By diverging from the influence of Freudian psychology, and developing a form of Jungian feminism, I propose the existence of an essential female Self which transcends the constraints of societal expectations and physical violence. In this work, both Hester and Frances emerge as physically and psychically strong entities who were forced to adopt socially conformist personae to survive.
