The specific machinery of Anna's downfall derives from Tolstoy's basic moral philosophy: Unselfish seeking of goodness obtains a state of grace, whereas a predatory self-assertion results in damnation. We see how Anna becomes cruel, vindictive, and self-destroying as she exists according to her single goal — to maintain her love relationship. This becomes harder to maintain as Anna loses, one by one, the outside values of the social order which structure not only her existence, but Vronsky's as well. Shut off from her son, her friends, her protective status, Anna's love provides her with the only source of vitality. Under the pressure to live only through her love, she denies her femininity as the vehicle of bearing children; her charms have become the singular weapon of the witch. Thus we see why Vronsky shrinks from her heightened beauty: It is to her witchlike metamorphosis that Vronsky responds so coldly, driving Anna, in her turn, to a state of jealous desperation which further repels him.
