The media are now redundant. In an overview of developments spanning the past seventy years, Siegfried Zielinski's "[ . . . After the Media]" discusses how the means of technology-based communication assumed a systemic character and how theory, art, and criticism were operative in this process. Media-explicit thinking is contrasted with media-implicit thought. Points of contact with an arts perspective include a reinterpretation of the artist Nam June Paik and an introduction to the work of Jake and Dinos Chapman. The essay ends with two appeals. In an outline of a precise philology of exact things, Zielinski suggests possibilities of how things could proceed after the media. With a vade mecum against psychopathia medialis in the form of a manifesto, the book advocates for a distinction to be made between online existence and offline being.
