+Before textual technologies, there was no text. Before computers and word
+processors dealt with fixed 1-dimensional arrays of characters, typewriters
+placed letters in a grid---but not a particularly fixed one--- anywhere on a
+page, and the letters intermingled with writing and white-out and whatever else
+you could stick on. Before typewriters imposed (or suggested) the grid, to
+write by hand was to suggest your own lines, to form letters as necessary and
+useful, to cross out, underline, squiggle. Before that, what? Figures? A little
+arithmetic, a little ritual signification? At a certain point there wasn't even
+the 2-dimensional plane.
