are these humans the best thing in this savage garden , warring as they have done so long upon one another or are they simply an undifferentiated part of it , no more complex ultimately than the crawling centipede or the slinky satin-skinned jaguar or the silent big-eyed frog so very toxic that one touch of his spotted back brings certain death what have the many towers of great caracas to do with this endless sprawling world that comes so close to it whence came this metropolis of south america , with its smog-filled skies and its vast teeming hillside slums beauty is beauty where you find it .
