In most cases, one can learn at least as much about the writer and the culture of his era from such descriptions as one can about the animals. Literature about animals is relatively less self-conscious, and, for that reason, more revealing than writing directly about human beings. We are less defensive, so egotism and paranoia, while present often enough, are less elaborately concealed. Animals always figure very prominently in the symbols that express human identity, from heraldic crests to the names of sports teams.
