<p>The Ghetto traces back to the medieval era the Jewish immigrant colonies that have virtually disappeared from our modern cities--to be replaced by other ghettoes. Analytical as well as historical, Wirth's book lays bare the rich inner life hidden behind the drab exterior of the ghetto. The book describes the significant physical, social, and psychic influences of ghetto life upon the Jews. Wirth demonstrates that the economic life of the modern Jew still reflects the impress of the social isolation of ghetto life; at first self-imposed, later formalized, and finally imposed by others through a variety of extralegal mechanisms.
