I Feel Like A Number

I've been thinking. A dangerous past-time, I know... But, I have. I have been thinking about emotions. How they work, how some are easier to understand than others, how some seem more, for lack of a better term, comfortable on some people than others. And chief amid all this quandry is the following question. Can we quantify emotions? Can we separate them out like portions of sugar for a baking recipe and figure out the 'level' of an emotion we feel? Is it possible to measure an emotion on a 0-10 scale like doctors ask us to do for pain? Some say we can. I'm not so sure. At least, not with certain emotions anyway. Pain has always been pretty easy for me to measure on that scale. If I'm in pain (Good or Bad) and you ask me, I can give you an approximate number right off. But emotions are a completely different animal. Hell, it's a zoo full of completely different animals. They are much more ethereal than pain. Harder to grasp and pin down and say "This is exactly what I'm feeling and this is why and here,tify easier because I'm more familiar with them. Anger being the main one. Sad as that is. And Sadness I can probably rate pretty quick if called to do it. But things like Love and Joy are harder for me. By a long shot. And believe me, I'm not an Emo, boo-hoo, the world hates me kinda guy. Seriously. Even though that statement about the emotions I have harder time with may make it sound that way. I'm just trying to figure some things out that have been bouncing around in my noggin and so, here I express them as a part of that sometimes awesome, sometimes sucky process. In fact, not only am I doing that but I invite and challenge any of my readers to post their take on this subject, either through comments or, better yet, though full posts, similar to how Doll recently had several of us do about Humility on her blog.
So, in short, the jury is still out for me on whether or not one can accurately measure emotions by a number or some such thing, though I am leaning towards No. What do you think? Can it be done?
