In spite of what you can immediately suggest your title, the central object of this book is not the origin of things. The chapters that compose it elaborated in detail that problem in each case: subjectivity and the subject, the miracle as origin, the objects that we grant "origin denomination", the patrians, language, human being, life, the cosmos. But the central object of this book is what humans have been doing when using the notion of origin, in a sample of their inexhaustible forms or versions.
It is inquired here, above all, the social uses that have been giving to that notion, the epistemic roads that we have attracted to its seductive power, the entities that we build as real as it is aroused in its name. Those uses, roads and entities are full of interpretive difficulties. The examination of these difficulties allows configuring the forms of origin as a picture of reasons for thinking about the world.
Origin, origins operate as keys of what we take for granted and do so as radically intimately that we barely notice them. Putting the focus on such notions can then be a way of encouraging almost any form of critical thinking.

Almost without pretending it, this book has come to be a choral piece with the following voices: Nancy A. Konvalinka, María Isabel Jociles, Fernando Lores, Álvaro Pazos, Livia Jiménez Sedano, María García Alonso, Honorio M. Velasco, Montserrat Cañodo, Carlos A. Pamazón, Pablo Sánchez León, Wenceslao Castañares, Luis Díaz Viana, Peter Mason, Eugenia Ramírez Goicoechea, Stéphane Tirrd, Helge Kragh, Leopoldo A. Moscoso, Manuel Gutiérrez Estévez and Angel Díaz de Rada. All of them contribute from various specialties to a reflection on which it surprises the strength of the notion of origin to regret a polyphony of analogous motifs: a plot of senses.
