Anna Karenina Part 7, Chapters 13-17
Kitty gives birth. Levin finds the whole experience surreal, and Kitty finds it entirely peaceful, even though she is in a great deal of pain. When he first sees his newborn son, Levin is surprised by what he feels: pain. He knows his son will suffer in the world, simply because his son is human.
