In a context marked by unprecedented challenges (the struggle against inequalities, climate change, etc.), innovation appears to be the readymade universal scapegoat. Innovation for Society, however, suggests that we look at innovation differently, by inviting us to innovate with consciousness. To do this, the authors introduce an approach they call Penser le Sens de l'Innovation (P.S.I., or "thinking about the meaning of innovation"), comprising a set of tools largely from the humanities and social sciences (observation, cartography, creativity, storytelling, etc.) to lead us to this "meaning". By considering the question of "meaning" from the point of view of both direction and signification, the authors rehabilitate the eminently political question of knowing which innovations we choose for which societies.
