This course is a required course for the Gender Studies program, aimed at guiding students to understand the development of feminist thought and the viewpoints of various feminist schools, in order to strengthen their theoretical foundation in gender studies. The subtitle of the course, "Solidarity and Difference," highlights the first wave of feminism's emphasis on the spirit of "solidarity among women," as well as the later development of feminist thought into "politics of difference," emphasizing that women occupy either central or marginal positions in society due to factors such as class, race, religion, and migrant labor status. Upon completing the course, students should be able to grasp the basic assertions of different feminist discourses, understand the permeation and tension between them, and recognize how feminism has been influenced by the social environment and other social issues, leading to varying expressions of feminist thought. The course aims to help students understand feminism as a dynamic and evolving ideology, rather than a rigid doctrine.
