This first volume contains almost all of the texts of Gilles Deleuze published in France and elsewhere between 1953 and 1974, from the appearance of "Empiricism and Subjectivity", his first work, to the debates that followed the publication of "The Anti-Oedipus", written with Félix Guattari. The collection consists mainly of articles, papers, prefaces, interviews or lectures already published, but not on any other work of Deleuze. A second volume contains the texts of 1975-1995, entitled "Two crazy schemes and other texts." "What's happier than air time?

The philosophical vitality is very close to us, and political vitality. We are close to many things and many key repeats, many changes ".
