In his philosophical treatise in preparation Péter T. Zselensky, writer, poet, translator and journalist professes himself to be a full-time bum, a survivor and last but not least a Diogenides, i.e. a descendant of Diogenes. He abandoned his flat, books and records a long time ago, however his company is sought after by students because he is a refined and cultured man who claims to have revived the five hundred-year-old tradition of philosophical dialogue. Péter’s real identity however vanished in the haze. As the accounts of a social worker reveal there are many ”Diogenides” wandering the streets. They are highly educated people, speaking several foreign languages, who can ”produce” the most amazing life stories.
