The book by one of the most famous contemporary French sociologists, Bruno Latour, is a manifesto of a new and rapidly developing direction of science, which finally unites physicists and lyricists. Based on the latest achievements in the sociology of science and technology, the author develops a new theory of knowledge, where social sciences are not in a privileged position in relation to natural sciences (or vice versa), and people and things participate together in the creation of the world in which we live.
