The word denoting 'forgiveness' has never been heard?

"The words denoting lying, deceit, greed, envy, slander, and forgiveness have never been heard. They have no jealousy, no sense of possession, real. What I thought a dream."
(Smith, The New World)

Malick takes almost all his dialogues from written sources. He is absolutely addicted in quotations, paraphrases and allusions (by the way, with images it is just the same: Murnau, Ford, Hitchcock, Visconti, Fuller, Buñuel, Pasolini, Godard….). Some are very well recognizable, some are not. That one was easy to identify. It is from Montaigne (Of Cannibals, 1572):

“the very words that signify lying, treachery, dissimulation, avarice, envy, detraction, pardon, never heard of.”

Montaigne’s affirmation must be understood in its cultural and political background. By the way, his essay was one of the sources of Shakespeare’s The Tempest.

PS: I am not suggesting these words have the same meaning in the mouth of Smith. That’s something that you have to judge.
