Introduction

This introduction presents an overview of key concepts discussed in the sub sequence chapters of this book. The book describes the principal topological unit that the late Lacan calls the Borromean knot or chain. It shows the logic of structure in Lacan which represents a subject for another signifier. It talks about discourse theory as presented by Lacan to Roman Jakobson, Lacan adds a new matheme to his already existing ones. It discusses on The structure of the drives, the Lacan emphasis on Freuds dissident notion of the drives. It discusses on the Topological dimension, how the bond of mirror-stage oneness between mother and infant is broken by a third term. It discusses on The practice of the letter, focusing Lacan axiom from The Ethics of Psychoanalysis saying that every truth has the structure of fiction and that truth and fiction are linked by the letter.
