"Levin said what he had genuinely been thinking of late. He saw nothing but death or the advance toward death in everything. But his cherished scheme only engrossed him all the more. Life had to be got through somehow till death did come. Darkness had fallen, upon everything for him; but just because of this darkness he felt that the one guiding clue in the darkness was his work, and he clutched it and clung to it with all his strength."
Leo Tolstoy, Anna Karenina, Book 3, Ch. 32
