Stupidity is of all times but each time has its own stupidity. Flaubert inspired us by defining the forms of a stupidity that is neither the eternal nor the timeless type. Instead, this stupidity appears as the symptom of an age, lending it its features — i.e. the platitudes, preconceptions, and worn-out words that form, in their rigidity and conceit, manifestations as hard as rock. In our time of artificial intelligence, the purpose here is to highlight, analyse, and question some of the figures of contemporary stupidity, which cannot be entirely identified without us turning to another word of the same semantic field: idiocy.
