Quote from : I Am Legend and Other Stories Book

Robert Neville looked out over the new people of the earth. He knew he did not belong to them; he knew that, like the vampires, he was anathema and black terror to be destroyed. And, abruptly, the concept came, amusing to him even in his pain. ... Full circle. A new terror born in death, a new superstition entering the unassailable fortress of forever. I am legend.
