Translation is at the heart of the humanities, and it arises in every discipline in the social sciences and beyond, but it is not easy to say what it is. This course looks at the role of translation in the past and in the world of today, in fields as varied as anthropology, the media, law, international relations and the circulation and study of literature. It aims to help students grasp the basic intellectual and philosophical problems raised by the transfer of meanings from one language to another (including in machine translation) and to acquaint them with the functions, structures and effects of translation in intercultural communication.
