Antiquity left the world not only the legendary ensembles of antiquity and the classical works of Sophocles, Euripides, Phidias, Aeschylus, Aristophanes, but also the heterogeneous world of squares and city streets with their constantly boiling passions and life. The book tells about the philosophy of the Cynics, which in its own way reflected the worldview of the oppressed strata of slave-owning society, about the amazing sages Antisthenes, Diogenes of Sinope, Kratet, their lifestyle of preaching, about the influence of their teachings on subsequent generations.
