Abstract: This second issue of 2016 facilitates communication between that which is part of the clinic and the technique on one hand, and clinical research and psychoanalytical theory on the other. A dialogue on limits and boundaries, created within and between the articles, which evokes the infinitesimal limits of the detail, either bound by the confines of early mental life observed in minute detail or, maintaining the prehistory of the verb as timeframe, revealing the limit represented by the archaic.
