After a few centuries of speeding up, the distribution of GNP's growth rates has widely changed all round the world. Growth is slowing down in advanced countries and has accelerated in emerging countries. Moreover growth is questioned as a matter of principle. Considering the vast array of issues at stake, mainly the depletion of natural resources and the enduring waste of human resources caused by mass unemployment, growth has reached a new stage. Economics needs to be provided food for thought from social sciences as well as from geography, natural sciences and philosophy : growth is a field of research open to co - disciplinarity. History shows how important the intellectuel climate, the zeit geist has been and still is for economic performances. As regards the future of growth, we explore two feasible scenarios able to conciliate at least two of the following goals : better protection and maintenance of natural resources, satisfaction of human aspirations to get better life conditions, alternative activities to paid jobs and idleness entailed by the labour saving technologies and significative efforts of households to temper their consumption.
