Who is this round gentleman who appears almost every afternoon in the same spot of the city park and engages passersby in lively conversations? A sage, a wisecracker, a clown, a contentious philosopher? Many shake their heads and walk on, while others listen to him, discuss with him, and find themselves returning to the same place time and again. He himself writes nothing down, but his listeners take notes. The small white book presented here, resembling a pocket calendar, contains the reflections and provocations of this peculiar contemporary, who shares the same name as the last letter of the alphabet. With subversive energy and a few sentences, Mr. Zett undermines arrogance, megalomania, and false authority. He is reluctant to trust institutions and considers nothing to be "inevitable." However, not everything he says should be taken at face value.
