'Beauty is truth, truth Beauty,' - that is all Ye Know on earth, and all ye need to know.                      John Keats: Ode to a Grecian Urn

If you will be persuaded by me, pay little attention to Socrates, but much more to the truth; and if I appear to you to say anything true, assent to it; but if not, oppose me with all your might, taking good care that im my zeal I do not decieve both myself and you.                             Plato: Phaedo
