The world has changed rapidly in recent decades: The world population and life expectancy are increasing; traditional large collectives such as nations, denominations and parties are losing their binding force; knowledge that used to be stored in libraries and had to be acquired with great effort is now available to us everywhere. Change has long since reached such a scale that, according to Michel Serres, we can justifiably say that members of the younger generations belong to a different species: that of the "little thumbs" who control their smartphones with nimble fingers, network and communicate. The great philosopher Michel Serres dedicates this declaration of love to the "little thumbs". Far away from any anti-technology cultural criticism, he calls on them to seize their chance and reinvent everything: society, the educational system - and themselves.
