In some ways we want definitions that can help protect our own interpretations of the genre.

When you're a young writer and you look at people praising a big hefty anthology that has uncovered a long lost genre, it can be disorienting to look inside it and think, "But what it's uncovered still isn't me. What does this mean? Do I not belong in this genre, or is there more of the genre yet to find?"

An essay is something that tracks the evolution of a human mind.

I never really understood the idea that nonfiction ought to be this dispensary of data that we have at the moment. Also, roughly around the time we were doing this fact-checking. And I never really understood why people think what nonfiction's job is to give them information as opposed to something else.

People like to say that Plutarch's is a really "personal" voice, but in truth Plutarch tells us very little about his life. His voice is personable but never personal. It feels intimate because he's addressing the world as we experience it, at this level, a human level, rather than way up here where very few of us live.

An essay is something that tracks the evolution of a human mind. It tracks the evolution of a single consciousness in order to give us an experience - an experience of looking for something and then finding ourselves in a different place by the time we've finished our journey.

Yet there are some critics in the nonfiction world who still look at some of today's stranger interpretations of the essay and say "You don't belong here. That's not how we do things." I think that's problematic.
