Now and again you discover the perfect pen and carry it everywhere until one day you lose it. But nothing is so universally dependable, or comes so naturally to hand as a pencil. What could be simpler? For much of my life, I have lived with one behind my ear: either to mark out saw cuts or mortices for carpentry or to scribble marginalia or underlines when reading. I often write with a pencil. It suits my tentative nature. It allows me literally to sketch out ideas before proceeding to the greater definition of ink. It was the first tool I used to write or draw, and still suggests the close relationship between the two activities. I know I shall never outgrow pencils. They are my first, most natural means of expression on paper. It is comforting and liberating to know that you can always rub out what is pencilled. It is the other end of the spectrum from carving in stone. The pencil whispers across the page and is never dogmatic.
