Can we separate the reason with genders? In this article, I hope to explain the answer to this question in relation to social institutionalized practices. Concentrating on relationship between dualist mindset that emerged in the conceptualizing reason, namely reason-body duality, and dichotomy of masculinity-femininity expressed in symbolic order, I aim to exposition the masculine character of asserted genderless reason and identify with between woman and nature. I turn to the Ancient Greek world as the source of the first identification of the reason with masculine codes, and consider the relationship between the social and the intellectual in three different contexts. The first of these contexts is the first section I deal with the position of women in Athenian society in the gender practices. In this episode, I am interested in the appaerance of gender practices in the Athenian society into the political shpere. In the second part, I examine that the misogynistic pattern at the source of the new legality in the Oresteia trilogy. In this work, which focuses on the trial of Orestes, I consider the misogynic relataion of the source of the nomoi, criticising the reduction of the representation of femininity to birth. Finally, in the last part, I focus on the representations of femininity and masculinity in Plato’s Timaios and Symposium. I crticize the fact that the identification establishen between reason and masculinity determined the representation of femininity as the other, by adressing to the fact that the conceptualization of the reason occurs within gender practices.
