Ayn Rand, The Fountainhead
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.
That’s the privilege we have as students of medicine , learning about the human body , how it works , it has fascinated artists over the years and it is privilege and blessing to ve learning all this.
