The savage, who has need of no one, and envies no one, neither knows nor seeks to know any other country but his own. If he requires more land for his subsistence he shuns inhabited places; he makes war upon the wild beasts and feeds on them. But for us, to whom civilised life has become a necessity, for us who must needs devour our fellow-creatures, self-interest prompts each one of us to frequent those districts where there are most people to be devoured. This is why we all flock to Rome, Paris, and London. Human flesh and blood are always cheapest in the capital cities. Thus we only know the great nations, which are just like one another.
