Through her investigation of fragile entities, philosopher of science Vinciane Despret sheds new light on our relationship to the deceased. Through a relation of obligations, the dead put the living to work. The living take care of their deceased by choosing to respond to the call. Practices of memory modify, densify and colour our under-standing of our living environment and create specific ambiances. Focused on the singular link of a Georgian family with their deceased, Nino Kirtadze’s film, Tell my friends that I’m dead, enlightens the full scope of these fragile entities at work on the existing. Through this documentary, we identify the invisible chains that generate ambiances above ground and outside time. Furthermore, transgenerational psychoanalyst Christine Ulivucci conducted critical analysis showing that ambiance memories, sensitive impressions are rooted in our personal history. The encounter with familiar places or objects activates reminiscence and produces what we call: fragile ambiances.
