This paper surveys the recent literature on modernity and on postmodernity and relates them with the neoliberal ideology that for thirty years was dominant in the world. In relation to modernity, it claims that major sociologists were not neoliberal, but their theories depicted a provisory modernity excessively conditioned by the neoliberal years. In relation to postmodernity, it criticizes its excessive relativism and pessimism, as well as their rejection of the great narratives and of the possibility of progress.
