`titrebConstructing a past, inventing a possible future`/titreb Freud’s notion of construction (1937) was extremely innovative in so far as constituted an integral part of analytic technique. It constituted, in short, a necessary process regarding experiences that had not been lived through as such, that were impossible to remember, and to which non neurotic defences, that is to say, splitting, hallucination, projective identification, testified. Construction predominantly entails a counter-transference. We also wish to underline the role of construction with the other in an analytic space that essentially constitutes a transitional space, a space for play, in which things « are and are not what they seem to be ».
