Non-binary gender as an umbrella term refers to any gender beyond the male/female categories. With the progressing LGBT+ movement and future predictions referring to all persons equally „regardless of their chosen gender” (Cave, Klein, 2015), the question of philosophical and societal limits of being non-binary is a fundamental one for understanding the patterns in the current sign system. Binary, as such, is of a philosophical nature and can be interpreted as political; as in the works of Jacques Derrida and Judith Butler who both accelerated feminist criticism by analysing how the masculine is privileged in the construction of meaning. Also, for Martin Heidegger binary is a subject of criticism as he tried to establish a new dualistic-thinking humanism in which being comes before metaphysical oppositions. The goal of this article is to compare the approaches of these three scholars to find the possibilities, preconditions and limits of non-binary gender. The author argues that the point of clash of their arguments dwells in the interlinkage of thinking, acting and signifying of a politicized material body. All of them problematize authenticity and repetition.
