In Between Men, Eve Kosofsky Sedgwick forward the idea that gender relations in the Euro-American society since the second half of the 19th century are underpinned by between men. In Epistemology of the closet, it generalizes this thesis by referring the whole culture of this company to the definitions of homosexuality and heterosexuality. It demonstrates with admirable acuteness the contradictions of these definitions, the contradictions that affect their periphery least their very center. The analyzes are fine, incisive, rigorous; the style is precise, academic, and sometimes irresistible humor. These 260 pages, the importance is not less than that, at random, Words and things or the Anti-Oedipus, gives as little, the impression to understand the essential things and without them we have escaped: the society in which we live, one that has formed us as we are and thus also about ourselves. Reading it is necessary not only to all those interested in gender issues, gay studies and queer theory, but also to all those interested in psychology, history of mentalities, culture "Western" modern and contemporary, etc: in short, in many of the world. And since Sedgwick demanded a practice of critical theory does not exclude the positions taken, and hence some effectiveness outside of the academy, let us say bluntly: this book is hope that s' it was read and popularized its ideas, the world would be better.
