"The capacity to resist coercion stems partly from the individual's identification with a group. The people who stood up best in the Nazi concentration camps were those who felt themselves members of a compact party (the Communists), of a church (priests and ministers), or of a close-knit national group. The individualists, whatever their nationality, caved in. The Western European Jew proved to be the most defenseless. Spurned by the Gentiles... and without vital ties with a Jewish community, he faced his tormentors alone—forsaken by the whole of humanity."
