The distinction between the reified universe of science and the consensual universe of common sense introduced by Serge Moscovici in the Psychoanalysis and reiterated in further texts always gave rise to debate and puzzled interrogations.In the present text it is argued that for Serge Moscovici there is both a discontinuity and continuity between the two fields of science and common sense although at different levels of analysis.They would be discontinuous at the operative theoretical level corresponding to the logic of verification (...) in the sense of Popper. Truth and truthfulness are not the same. But there would be continuity at the metatheoretical thematic level, where either scientists or lay people seem to follow the same non conscious insightful processes enabling them to look beyond the empirical observables as well as beyond the traditional beliefs and common places.
