"Africa is never the same to anyone who leaves it and returns again. It is not a land of change, but it is a land of moods and its moods are numberless. It is not fickle, but because it has mothered not only men, but races, and cradles not only cities, but civilizations - and seen them die, and seen new ones born again - Africa can be dispassionate, indifferent, warm, or cynical, replete with the weariness of too much wisdom."
