The paper shows affinity between cyberfeminism and thinking of J. Butler. The first part sums up Butler's texts. The identity is an effect of a repetition of subjectivation practices transmitted by the society. The materiality of the body and the structure of the mind are not conditions but consequences of culture, which are retrospectively naturalized. It's not possible to resist the power from a position of an autonomous subject because subject itself is a product of knowledge-power. The only possible subversion acts from within the power network showing the relativity of the subjectivation practices by means of irony and parody. Cyberfeminism is not a unified paradigm but a network of activities in art, culture, theory and technology. The differences between nature, culture and technology are disappearing today. Animals, humans and machines are melting together to cyborgs - computer-humans. The cyborg-metaphore is an ironic political myth, subverting the foundations of modernity. The obvious artificial and floating identity of a cyborg is (similar to Butler's theory) produced by inscriptions of culture-science-technology showing the relativity of ''natural essence'' and ''autonomous subject''.
The article presents the contemporary feminist stream of new materialism, and compares and contracts it with the linguistic branch of poststructuralism which has been criticized by new materialism for neglecting matter. The paper first discusses points of departure these two streams share, specifically, a critique of Western metaphysics, and in particular the fundamental interrogation of dualities and the idea of a stable inner essence in Western thought. Consequently, the article shortly introduces the starting points of new materialism and presents Judith Butler’s ideas on matter which are pivotal for the comparison that follows. The comparison of the two streams concentrates on the following issues: ontology, power, the abject, difference, subject and embodiment. The article stresses strong and weak points of both the streams and presents them as complementary rather than contradictory approaches., Hana Porkertová., and Obsahuje bibliografii
