We have built no national temples but the Capitol; we consult no common oracle but the Constitution.
— Rufus Choate

And if we now cast our eyes over the nations of the earth, we shall find that, instead of possessing the pure religion of the Gospel, they may be divided either into infidels, who deny the truth; or politicians who make religion a stalking horse for their ambition; or professors, who walk in the trammels of orthodoxy, and are more attentive to traditions and ordinances of men than to the oracles of truth.
Samuel Adams oracles quote

For what are the classics but the noblest thoughts of man? They are the only oracles which are not decayed, and there are such answers to the most modern inquiry in them as Delphi and Dodona never gave. We might as well omit to study Nature because she is old.
— Henry David Thoreau

As an example of just how useless these philosophers are for any practice in life there is Socrates himself, the one and only wise man, according to the Delphic Oracle. Whenever he tried to do anything in public he had to break off amid general laughter. While he was philosophizing about clouds and ideas, measuring a flea's foot and marveling at a midge's humming, he learned nothing about the affairs of ordinary life.
— Desiderius Erasmus

Poetry is the utterance of deep and heart-felt truth -- the true poet is very near the oracle.
