I read this today in Great Expectations:
That she had done a grievous thing in taking an impressionable child to mould into the form that her wild resentment, spurned affection, and wounded pride, found vengeance in, I knew full well. But that, in shutting out the light of day, she had shut out infinitely more; that, in seclusion, she had secluded herself from a thousand natural and healing influences; that, her mind, brooding solitary, had grown diseased, as all minds do and must and will that revere the appointed order of their Maker; I knew equally well. And I could look upon her without compassion, seeing her punishment in the ruin she was, in her profound unfitness for this earth on which she was placed, in the vanity of sorrow which had become a master mania, like the vanity of penitence, the vanity of remorse, the vanity of unworthiness, and other monstrous vanities that have been curses in this world?
