It isn't uncommon for someone to look at a weed growing in an inhospitable location like a parking-lot crack and have a fleeting thought of respect for the cleverness of the weed. Of course, it's a mistake to anthropomorphize a weed. The weed is no smarter than evolution has selected into its genes.
■ Yet we should recognize that nature does have a characteristic that we would recognize as intelligence, even if it isn't truly sentient. Sometimes intelligence shows up simply in adaptation to circumstances and the development of responses to those circumstances. A conditioning effect, as it were.
■ There are plenty of human beings who demonstrate the same kind of quasi-intelligence, and we often struggle to depict it correctly. Sometimes it's called "cunning" or "guile". Other times, it's even begrudgingly described as an "animal intelligence".
■ These people adapt their behaviors around circumstances or respond to stimuli in a way that almost looks like intelligent thought -- but most people of goodwill struggle to call it that, because it isn't a sense of deliberate, enlightened self-improvement. That's what we usually like to describe as "intelligence": It can start as a gift, but it takes form when the holder decides to make something better of themselves with it.
■ Enlightened self-improvement comes from a choice. There lots of people who show that kind of enlightened self-improvement, even when they are not innately "smart". That's what makes it laudable: Enlightened self-improvement can be undertaken by almost anyone. What we shouldn't do is applaud people who simply adapt, weed-like, around circumstances for selfish gain.
■ Words matter. Often, the lack of good words to describe things matters quite a lot, too. That we don't have an evident turn of phrase for this "weed intelligence" is a misfortune for us all, especially because those who exhibit it are often the ones of whom we ought to be most wary. Monsters are scariest when we can’t name them.
