People in Germany have an indifferent to poor relationship with our society. In fact, modernity, i.e. the last 200 years, has given the population historically unprecedented progress: democracy, human rights, social security systems, nutritive abundance. Yet this is little appreciated. This may be due to the fact that, in Diderot's sense, we have to prove ourselves permanently, that is, we live in a meritocracy that produces suffering. However, totalitarian ideologies have also emerged and been implemented in modernity, for which modernity is also responsible. This essential shows that psychology, on closer inspection, turns out to be the defender of the good parts of modernity.
