Mouths are weird. They’re not quite like other parts of our body, most of which are ‘objects’ in themselves, even though they are sometimes reducible to smaller parts. A hand has fingers, a palm, and so forth, but is also what it is: a hand. A mouth has lips, teeth, gums, a tongue, but it is nothing in itself. A mouth is an emptiness.Bear with me here. See, a hand, you can stick a hand on other things and it will still be a hand. If you had a hand on the top of your head, high-fiving would be super easy. The same applies to a mouth. If I had a mouth between my buttcheeks instead of my facecheeks, I could talk to you with it and eat stuff with my brand new assmouth. So far so good.
But what if you want to affix a bodypart to itself? Sure, stick a small hand on the top of my hand. It’s still a hand, but with an extra hand. Or maybe on the tips of our fingers, so we can give eachother tiny handshakes. In the latter case, the mouth still works: you can put tiny mouths on parts of your mouth, like your teeth. Or maybe a tiny mouth in the middle of each of your lips.
However you try, though, you can’t stick a mouth on a mouth. A mouth is not a thing. It is structure without essence. A mouth is a negative space. It is an abyssal threshold through which things pass to be devoured.I know of one properly recursive mouth in cultural history, and that is the Alien from the Alien movies. It is, appropriately, called a Xenomorph, which literally means ‘weird shape’. And even then: this is a mouth in a mouth. Point made.
Maybe that’s why mouths are so fascinating. They are concepts, and they are on our body, but they aren’t actually things. That’s all I wanted to say really. Mouths are weird.
