The study guide is intended for University students of philosophy and sociology departments. The guide traces back the interconnection of sustained philosophical development and its contribution to positive social changes. The guide elucidates the prominent ideas of philosophers' community from classics such as Karl Marx, Herbert Spencer, Max Weber, Emile Durkheim to modern scientists Wilhelm Dilthey, Jurgen Habermas, Kwame Anthony Appiah, Simon Blackburn, Robert Brandom, Judith Butler, paying special attention to the analysis of the most significant social phenomena. The aim of the study is to improve students' reading, writing and speaking skills and enlarge their topical vocabulary. The guide encompasses fifteen units and each unit includes the main text on a topic and a wide range of exercises. The after-text exercises offer a great number of multiple choice tasks, gapped texts, matching the words and expressions from the texts with their definitions and discussing points based on modern philosophical and social issues. The videos devoted to the work of classical and modern researchers are expected to arouse students interest to the problems mentioned above.
