From Emerson, I learned two fundamental truths: first, that we learn by expressing, not by thinking, which is to say that knowledge doesn’t really exist until you can write it down. What we normally imagine as “thinking” is really just a distracted form of writing, like having a disoriented drunk at a typewriter behind your eyes. Writing sobers him up. The pen (or the word processor) lets the mind compose language into knowledge that’s far more sophisticated than what that little boozer can do on his own.
