Stupid is as stupid does
Although it's the only thing I have going for me that I value, intelligence is a highly over-rated, squirrelly thing. There's no useful way to quantify or compare the intelligence of two people, unless the disparity is so great that to remark on it just seems petty. Even then, who decides that one's ability to quote obscure philosophers is more valuable than another's knack for always knowing what will happen next in a convoluted narrative?
More importantly, no matter how intelligent someone is, they are still eminently and inevitably capable of doing the stupidest things imaginable, from the trivial driving-for-miles-with-the-emergency-brake-on to the much more consequential taking-a-loved-one-for-granted-long-enough-that-she-leaves. Both of these things can and will be done by people of every quintile of intelligence. The latter even moreso by the more intelligent, as they are encouraged to devalue emotion and rely on reason; he who searches endlessly for the perfect expression of love will most likely be left long before he finds it, while he who simply convinces you that he loves you and supports you won't be. Now who's more intelligent?
I've met someone who fascinates me many times in my life; I can't wait to talk to them again, or listen to them, or just experience life at the same time as them. Very few of these people have been available, attainable, or female enough that I'd have a romantic relationship with them, but I'm certainly aware that this level of interest in another person is a much more important component of love than is sexual attraction.
And yet, time and again, these people, who I had lovingly endowed with intelligence, wit, charm, and likeability, turn out to be fools just like everyone else. They all do stupid things, they all hurt others deliberately or accidentally, they're all insecure, they're all miserable at as many pursuits as they are brilliant at. This shattering discovery became less shattering each time it happened, however, as I became more aware that people, even those who care deeply for each other, and who want roughly the same thing, can annihilate the most fundamental aspects of their relationship, without even trying, even while exerting every effort not to.
Does this make these people stupid? Does it make one of them stupider than the other? Does this indicate that their relationship 'wasn't meant to be'? I think not; I think it makes them human, and I think it tells us a lot about modern life. While it was once possible to pore over a love letter until it was truly a work of art, and only then dispatch it, in a gently perfumed cloud, to its happy reception, that possibility was never truly available except to those of leisure and learning. The relentlessly increasing availability of both faster means of communication and of innumerable and more absorbing distractions rendered even that form of expression less relevant to those who had once valued it above any other.
So does someone that still takes the time to express themselves in this manner signal to the world that they are more or less intelligent than someone who does not? Did they take the time to learn to write so that their pleadings of love would set themselves apart through the ages? Did they master penmanship so that the page itself would become a work of calligraphic beauty? Did they hand-make the paper, the envelope, did they use a quill or a fountain pen, did they form the paragraphs into the shape of a heart, did they make the reader cry with recognition or delight, did they, in the short space of that letter's reading, render the reader incapable of ever wanting another? If not, should they simply not have bothered? Does it matter if they only did three of those things? If so, which three?
Who is more intelligent at this point: he who knows that more perfect missives than any he could possibly fashion have already been created, thousands of times over, and so doesn't even try, or he who doesn't care, that knows he wants to try, and so does? I suppose it depends who you ask. Am I more intelligent for having pursued this line of reasoning and learned something from it than someone who has not, or than someone who gleaned something different? Am I more intelligent than someone who gleaned something different, but didn't use the word 'glean'? Yes, probably, if you're going by standardized measures, but how about if they do it three months from now? Has the balance shifted? What if I did something really stupid since then, which I absolutely will have? Do we gain anything important from these comparisons?
No emotional or cerebral ability of anyone is ever written in stone; any such ability can be improved through practice, just like any physical strength. Any gaps in learning can be filled, any lack of tact or sensitivity can be improved, any sloppiness of expression can be tightened, any disconnect between two people can be bridged if they both want it to be. The key to any endeavor is the desire to do it. If you don't have that, then yes, you might as well give up.
