The Epistemology of the Closet (1990) is the most famous and influential work of one of the largest American feminist researchers, which greatly contributed to strengthening the authority of gay theory and overcoming the impasse of ideological and political pseudo-neutrality in the vast field of the humanities. The book contains both “theoretical introduction”, the famous “Axiomatics”, which gives the fundamental concept of the intertwining of two different but interconnected perceptions of homo- and heterosexuality, which permeates and largely determines all modern culture, and the “methodological part”, where virtuoso literary and cultural studies are carried out analysis of those texts by outstanding authors of the late 19th and early 20th centuries, namely Wilde, Nietzsche, Melville, Proust and Henry James, which marked the transition to modernity, and also provides an example of a “contrasting” study of cultural processes occurring today, against the background "Esther" by Racine. The publication is addressed to everyone who is interested in modern feminist and gay theory, as well as literary and cultural criticism in general.
