Now take a human body. Why wouldn’t you like to see a human body with a curling tail with a crest of ostrich feathers at the end? And with ears shaped like acanthus leaves? It would be ornamental, you know, instead of the stark, bare ugliness we have now. Well, why don’t you like the idea? Because it would be useless and pointless. Because the beauty of the human body is that is hasn’t a single muscle which doesn’t serve its purpose; that there’s not a line wasted; that every detail of it fits one idea, the idea of a man and the life of a man.
― Ayn Rand, The Fountainhead
