A hack, (Robert McKee) says, is a writer who second-guesses his audience. When the hack sits down to work, he doesn’t ask himself what’s in his own heart. He asks what the market is looking for. The hack condescends to his audience. He thinks he’s superior to them.
The truth is, he’s scared to death of them or, more accurately, scared of being authentic in front of them, scared of writing what he really feels or believes, what he himself thinks is interesting. He’s afraid it won’t sell. So he tries to anticipate what the market (a telling word) wants, then gives it to them.
In other words, the hack writes hierarchically. He writes what he imagines will play well in the eyes of others. He does not ask himself, What do I myself want to write? What do I think is important? Instead he asks, What’s hot, what can I make a deal for?
The hack is like the politician who consults the polls before he takes a position. He’s a demagogue. He panders.
It can pay off, being a hack. Given the depraved state of American culture, a slick dude can make millions being a hack. But even if you succeed, you lose, because you’ve sold out your Muse, and your Muse is you, the best part of yourself, where your finest and only true work comes from.
