I saw some piglets suckling their dead mother. After a short while they shuddered and went away. They had sensed that she could no longer see them and that she wasn't like them any more. What they loved in their mother wasn't her body, but whatever it was that made her body live.
There is something in the unselfish and self-sacrificing love of a brute, which goes directly to the heart of him who has had frequent occasion to test the paltry friendship and gossamer fidelity of mere Man.
