I’d say that that huh is the foundational block of curiosity. To get good at the huh is to get good at both paying attention and nurturing compassion; if you don’t notice, you can’t give a shit. But the huh is only half the equation. You gotta go huh, alright — the “alright,” the follow-up, the openness to what comes next is where the cascade lives. It’s the sometimes-sardonic, sometimes-optimistic engine driving the next huh and so on and so forth.
Form comes from wonder. Wonder stems from our 'in touchness' with how we were made. One senses that nature records the process of what it makes, so that in what it makes there is also the records of how it was made. In touch with this record we are in wonder. This wonder gives rise to knowledge. But knowledge is related to other knowledge and this relation gives a sense of order, a sense of how they inter-relate in a harmony that makes all things exist. From knowledge to sense of order we then wink at wonder and say How am I doing, wonder?
To understand what a real essay is, we have to reach back into history again, though this time not so far. To Michel de Montaigne, who in 1580 published a book of what he called "essais." He was doing something quite different from what lawyers do, and the difference is embodied in the name. Essayer is the French verb meaning "to try" and an essai is an attempt. An essay is something you write to try to figure something out.
If all you want to do is figure things out, why do you need to write anything, though? Why not just sit and think? Well, there precisely is Montaigne's great discovery. Expressing ideas helps to form them. Indeed, helps is far too weak a word. Most of what ends up in my essays I only thought of when I sat down to write them. That's why I write them.
The Meander (aka Menderes) is a river in Turkey. As you might expect, it winds all over the place. But it doesn't do this out of frivolity. The path it has discovered is the most economical route to the sea.
The river's algorithm is simple. At each step, flow down. For the essayist this translates to: flow interesting. Of all the places to go next, choose the most interesting. One can't have quite as little foresight as a river. I always know generally what I want to write about. But not the specific conclusions I want to reach; from paragraph to paragraph I let the ideas take their course.
