“My illness has… given me leisure and calmness for serious recollection” “I saw in my own behaviour since the beginning of our acquaintance with him last autumn, nothing but a series of imprudence towards myself, and want of kindness to others… My illness, I well knew, had been entirely brought on by myself, by such negligence of my own health, as I had felt even at the time to be wrong. Had I died, it would have been self-destruction.
"The kindness, the unceasing kindness of Mrs. Jennings, I had repaid with ungrateful contempt. To the Middletons, the Palmers, the Steeles, to every common acquaintance even, I had been insolent and unjust"
I believe that, in this speech, Marianne fairly concisely acknowledges everything we faulted her for in this group read. She used her time for reflection for a most serious introspection. Her innate intelligence and keen self-awareness can only leave the reader feeling good about her future. She sees her mistakes with such clarity, that I have know doubt she won't repeat them again. And as far as any future mistakes she may make, I believe now, she's ready to deal with them in a substantially more dignified manner.
Then she continues, "But you, -- you above all, above my mother, had been wronged by me..." After a lifetime of taking Elinor for granted, finally she sees the strength of her sister, and appreciates it in the manner deserved by her. While there's no doubt Marianne loved her sister before, only now does she truly understand just how important Elinor's love for her is, and how worthy Elinor is of her love.
