Finally, the authors described different vectors of Greek school development. One of the new streams was a Roman ‘Stoic’ idea. More specifically, this formation followed strict humanistic rules, notably represented by Seneca. The core idea of being stoic was for a person to remain indifferent in any situation since life prepares the challenges to humankind to make people stronger in their struggles. These ideas were considered innovative since stoics were the first who tried to face the problems instead of avoiding them and creating a ‘utopistic’ world.
