Probably no other person of the twentieth century has influenced scientific thought, humanistic scholarship, medical therapy, and popular culture as much as Sigmund Freud. This lecture course will study his work, its cultural background, and its impact on us today. In the first part of the course, we will learn about Freud's life and the Viennese culture of his time. We will then move to a discussion of seminal texts, such as excerpts from his Interpretation of Dreams, case studies, as well as essays on psychoanalytic practice, human development, neuroses, and culture in general. In the final part of the course, we will discuss the impact of Freud's work. Guest lecturers from the medical field, history of science, psychology, and the humanities will offer insights into the reception of Freud's work, and its consequences for various fields of study and therapy.
