Wittgenstein wrote that we cannot see what is familiar, because it is always before our eyes. Printed forms are both familiar and invisible in this way. So invisible that we don’t usually notice how strikingly innovative they are. When we talk of “manuscript” and “print,” however much we resist any simple opposition, it’s hard not to imagine manuscript as the technology of the Middle Ages and printing as the technology of the early modern and the modern. Yet blank forms reverse this before/after model.
