The social “tectonic plates” are moving at unparalleled speed, causing worldwide political-economic rearrangements. Chapter 1 gives an overview of these seismic events to situate the transformations of social knowledge production within a broader historical context. Bearing this in mind, it navigates with a bird’s eye perspective the main contents of the book. First, it critically analyses contemporary intellectual property theory and how it reflects influential epistemological considerations. Then, it develops a historical blueprint of how knowledge became the object of disputes over privatisation. Additionally, it examines three philosophical perspectives to explore scopes of legitimacy beyond the immediacy of the present. Finally, it unpacks how the privatisation of knowledge, catalysed by neoliberal tactics, ubiquitously impacts present-day social relations at all levels.
