In Constructions in Analysis Freud introduces the notion of constructions, different from interpretation, and considers it necessary - under certain conditions - to reconstruct a part of the infantile history of the subject. The difference between construction and reconstruction as well as which should be the limit of the intervention of the analyst in order to avoid a proposal far removed from the patient discourse, are a part of present debates on this subject. The editors, together with the contributors to this volume, accepted the challenge to consider Freudian ideas and its implications nowadays.
