“Другий стать” (translated as “The Second Sex”) is a foundational text in feminist philosophy written by Simone de Beauvoir in 1949. The book explores the construction of women's identity and the societal roles imposed on them, arguing that women have historically been defined as the "Other" in relation to men. De Beauvoir examines various aspects of women's lives, including their education, sexuality, and work, emphasizing the need for women to achieve independence and self-definition. The work has had a profound impact on feminist theory and continues to be a significant reference in discussions about gender equality and women's rights.
