Walter Kaufmann (1921-1980), The Faith of a Heretic
(1961; rpt. Princeton: Princeton University Press, 2015), p. 104:
[T]heology depends on a double standard. One set of standards
is employed for reading and interpreting one's own tradition and
its texts; another, for the texts and traditions of all other. Here,
one is committed not only to make sense of everything but to
make everything come out superior, profound, and beautiful;
there, one is not averse to finding fault and even emphasizing all
that is inferior to one's own tradition.
Id., p. 105:
Theology is antithetic not only to the Sermon on the Mount
but to the most elementary standards of fairness. It involves a
deliberate blindness to most points of view other than one's own,
a refusal to see others as they see themselves and to see oneself as
one appears to others—a radical insistence on applying different
standards to oneself and others.
