Abstract
There is a robust tendency within the contemporary feminist mainstream to argue against and ultimately reject the so-called ‘dualising or dualist philosophy’ since it is the supportive paradigm background for any gender discrimination originated from the hegemonic sovereignty of masculinity over femininity. In this paper, having dived deeper into the feminist critical depiction of the logical binarist foundation on which the dualising philosophy is said to be well-grounded, I will proceed to portray and examine a sequence of doctrines that feminist philosophers have developed to shed light on the fact that the hegemonic sovereignty of masculinity over femininity has been theoretically initiated from the logical disjunction 'p or not p' to masculinity essentialism. Finally, I will end by pointing to a tension between underlying assumptions of the feminist sequentialist approach and what feminists themselves claim to adhere to as the highest ideal: non-naturalising gender differences.
