Tests Walt Whitman

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.
