I can much more easily believe Mr. Bingley’s being imposed on, than that Mr. Wickham should invent such a history of himself as he gave me last night; names, facts, everything mentioned without ceremony. If it be not so, let Mr. Darcy contradict it. Besides, there was truth in his looks.
– Jane Austen
Pride and Prejudice, Chapter 17. Elizabeth shows her naivety here when she finds Mr. Darcy guilty of treating George Wickham badly, solely on the word of Wickham and without hearing the other side of the story. She doesn’t consider that Wickham may be lying and deceiving her – which he is! She remains blind to her prejudice against Darcy.
