Hm, paper. The pen and pencil are both altruistic devices, created for the sole purpose of acting as mediums from the user to the user's canvas. They give all the contents of their own existence towards this goal and, when they have run out, are discarded without complaint. The paper, however, receives only the contents of others' souls (the tool and the implementer) and, if it has achieved its primary directive, is actually retained and given additional value for the pieces of soul upon it that are not its own. (Think about this the next time you purchase stationary.
