Text: Farewell to you, my hopes, my wonted waking dreams; Farewell, sometimes enjoyed joy, eclipsed are thy beams;Farewell, self-pleasing thoughts which quietness brings forth;And farewell, friendship's sacred league, uniting minds of worth.
Entailment: Minds of worth are united by the friendship's sacred league.
Contradiction: Farewell is a word that wasn't used in a thousand years.
