In 1985, the French philosopher Jean-François Lyotard curated a groundbreaking exhibition called Les Immatériaux at the Centre Pompidou in Paris. The exhibition showed how telecommunication technologies were beginning to impact every aspect of life. At the same time, it was a material demonstration of what Lyotard called the post-modern condition. This book features a previously unpublished report by Jean-François Lyotard on the conception of Les Immatériaux and its relation to postmodernity. Reviewing the historical significance of the exhibition, his text is accompanied by twelve contemporary meditations. The philosophers, art historians, and artists analyse this important moment in the history of media and theory, and reflect on the new material conditions brought about by digital technologies in the last 30 years.

1985年，法国哲学家让-弗朗索瓦-利奥塔（Jean-François Lyotard）在巴黎蓬皮杜中心策划了一个名为Les Immatériaux的开创性展览。该展览展示了电信技术是如何开始影响生活的各个方面的。同时，它也是对利奥塔所谓的后现代条件的物质展示。本书收录了让-弗朗索瓦-利奥塔先前未发表的关于 "Les Immatériaux "的构思及其与后现代性的关系的报告。在回顾展览的历史意义时，他的文字伴随着12个当代的沉思。哲学家、艺术史家和艺术家们分析了媒体和理论史上的这一重要时刻，并对过去30年中数字技术带来的新物质条件进行了反思。
