Fanny's disgust at the greater part of this letter, with her extreme reluctance to bring the writer of it and her cousin Edmund together, would have made her (as she felt) incapable of judging impartially whether the concluding offer might be accepted or not. To herself, individually, it was most tempting. To be finding herself, perhaps within three days, transported to Mansfield, was an image of the greatest felicity, but it would have been a material drawback to be owing such felicity to persons in whose feelings and conduct, at the present moment, she saw so much to condemn: the sister's feelings, the brother's conduct, _her_ cold-hearted ambition, _his_ thoughtless vanity. To have him still the acquaintance, the flirt perhaps, of Mrs. Rushworth! She was mortified. She had thought better of him. Happily, however, she was not left to weigh and decide between opposite inclinations and doubtful notions of right; there was no occasion to determine whether she ought to keep Edmund and Mary asunder or not. She had a rule to apply to, which settled everything. Her awe of her uncle, and her dread of taking a liberty with him, made it instantly plain to her what she had to do. She must absolutely decline the proposal.
