ALL submit to them, where they sit, inner, secure, unapproachable to
analysis, in the Soul;
Not traditions--not the outer authorities are the judges--they are
the judges of outer authorities, and of all traditions;
They corroborate as they go, only whatever corroborates themselves,
and touches themselves;
For all that, they have it forever in themselves to corroborate far
and near, without one exception.
Walt Whitman
