In The Eye Of The Beholder

Last night at dinner with my friend K [yay!], we were talking about beauty. I had brought it up because I had been having the exact same conversation with another one of my friends because I had woken up a couple of days ago feeling like the ugliest person on the planet, and my friend told me not to be stupid [well, she's British, so obviously it came out a little more elegant than that]. But my question to K was this: what makes a person beautiful? I asked K to think of someone who most people agree is beautiful [NOT cute, pretty, hot - beautiful, just beautiful]; she came up with Catherine Zeta Jones, so I asked her: what does Catherine Zeta Jones have going for her that people say that she's beautiful? K said that she just has this aura about her, like the way she presents herself, and I said that that's not a quantifiable thing. That led me to the thought that perhaps beauty isn't quantifiable, maybe it just is the way one carries oneself. But it also has to do with a person's physical appearence, right? So what about a person's face makes them beautiful? We all have two eyes, a nose and a mouth. Is it the shape of the face? The size of the nose? The color of the eyes? What is it that defines beauty?
