Susan Bordo, a modern feminist philosopher, in her writings elaborates the dualistic nature of the mind/body connection by examining the early philosophies of Aristotle, Hegel and Descartes, revealing how such distinguishing binaries such as spirit/matter and male activity/female passivity have worked to solidify gender characteristics and categorization. Bordo goes on to point out that while men have historically been associated with the intellect and the mind or spirit, women have long been associated with the body, the subordinated, negatively imbued term in the mind/body dichotomy.[29] The notion of the body (but not the mind) being associated with women has served as a justification to deem women as property, objects, and exchangeable commodities (among men). For example, women's bodies have been objectified throughout history through the changing ideologies of fashion, diet, exercise programs, cosmetic surgery, childbearing, etc.
