This is evidenced in the philosophical agenda set in her first book "Patterns of Dissonance: An Essay on Women in Contemporary French Philosophy", 1991, which gets developed further in the trilogy that follows. In the next book, "Nomadic Subjects: Embodiment and Difference in Contemporary Feminist Theory", 1994, the question is formulated in more concrete terms: can gender, ethnic, cultural or European differences be understood outside the straitjacket of hierarchy and binary opposition? Thus the following volume, "Metamorphoses: Towards a Materialist Theory of Becoming", 2002, analyses not only gender differences, but also more categorical binary distinctions between self and other, European and foreign, human and non-human (animal/ environmental/ technological others).
