The book for beginners in theory! Deconstruction, constructivism, structuralism... we've all heard of them. But what are the differences? And what does it all have to do with me? Long mocked for their lack of concrete theories, the humanities have unleashed a true fireworks display of theories over the past fifty years. Who can still keep track in this confusion? Jochen Hörisch comes to the aid of the bewildered layperson. Clearly, precisely, and always with a smile, the literature and media scholar describes the most important models of thought from the last fifty years, including information on risks and side effects.
