Here is the revolutionary work of Bracha L. Ettinger, one of the most innovative contemporary feminist thinkers internationally. Matrix Proto-ethics is a selection of her most important essays translated and edited for the first time in Spanish. In this original and essential compilation, Ettinger re-articulates feminine subjectivity beyond the patriarchal psychic and ideological framework or the heteronormative framework that makes up the social and symbolic order, and reveals a new understanding of the Subject and the Object. “Proto-ethics” is the gesture of compassionate hospitality that originates in the matrix relationship between self and other, and represents a condition of possibility for ethics. The adjective "matrix" refers to the feminine dimension in human subjectivity. According to Ettinger, the relationship that originates in the intra-uterine experience represents the axis of the aesthetic experience and implies an ethical dimension. This paradigm, the matrix, allows different rereadings of modern and contemporary art, as well as new interpretations of literature. A profound and groundbreaking book of special interest to all those who work on the connections between philosophy, psychoanalysis, aesthetics, ethics, feminist and queer theory, and also recommended for students of humanities, art history, cinema and comparative literature.
