Abstract
In this paper I show that literacy is not, as is often thought, a necessary condition for civilisation; argue that it was not, as often thought, the crucial factor in enabling the modern world to emerge from earlier civilisations; report the disadvantages of literacy as expressed by Plato's character Socrates and Milne's character Piglet, and look at the relation of literacy to reasoning and to philosophy; trace the role of the idea of literacy in the nineteenth century protocol for creating national cultures, and speculate on further developments in the same line; and then discuss its role in the modern economy and in the future.
