"There are religiously committed Jews who are indifferent to
the concerns of the larger non-Jewish society. They are content
to reside in isolated communities with unconcern, if not actual
disdain, for the Gentile world and for the problems which afflict
humanity. This introversion can be explained as a reaction to
the centuries-old derision and persecution which have been the
Jewish historical experience and to which they were subjected
with particular ferocity in modern times. Nowadays, there are
particular aspects of moral perversion afflicting the general
society which are repellant to Jewish sensibilities. Nevertheless,
this insularity cannot be vindicated as authentic Judaism even if
it can be understood and justified in particular historical periods
and situations. "
Rabbi Joseph Soloveitchik, Man of Faith in the Modern World, p. 73.
