This book that I am making available here is a compilation and reprint of articles published in specialised journals that were not of general circulation and scope. It is written in chronological order that corresponds to the dates of publication and follows the development of the writing around the work of a multifaceted thinker, Enrique Pichon-Rivière (1907-1977), who was able to dabble in psychiatry and psychoanalysis as well as in art, literature and tango. Here I take as an object his theory in order to make an epistemic re-reading around various factors that constitute his work, such as: ontology, epistemology, semiotics, the constitution of the subject, politics, the social in the conformation of the subject and a large etcetera.
