"Because one can't not write. Because he has to. It is that simple... The writing is not for fame, money, or notoriety, but to fulfill a more personal need, the need to find out what one is thinking, the need to put it down so that it can be dealt with, the need to codify emotion." - Jane Piirto in Understanding Creativity
Rowan Williams, it would seem, concurs with this understanding of the act of writing as a self-discovery of sorts, a knowing by doing: "you only discover what you have to say in the doing of it."
