This book is short but ambitious. It aims at suggesting a new interpretation of the fundamental institutions of private law capable of making them part of the solution to current global predicaments. It advocates a broad diffusion of these interpretations and legal ideas not only among a new generation of lawyers but also among the lay population. Its ambition is to deploy private law where it belongs: in the collective intelligence of the common(s), as a counter-hegemonic tool to institutionalize a new common sense. Collective understanding of the law (basic legal alphabetization) is a pre-requisite for a desirable transformation of the status quo.
