    The idea that nations should love one another, or that business concerns or marketing boards should love one another, or that a man in Portugal should love a man in Peru of whom he has never heard—it is absurd, unreal, dangerous.... The fact is we can only love what we know personally. And we cannot know much.
    —E.M. (Edward Morgan)

    each new victim treads unfalteringly
    The never altered circuit of his fate,
    Bringing twelve peers as witness
    Both to his starry rise and starry fall.
    Robert Graves (1895–1985)
