Few events in human history have had the same impact as the advent of the written word. Many experts believe that writing so fundamentally changed the human consciousness that it’s hard for everyone, even those who cannot read, to comprehend how human beings thought before writing. Plato was among the few visionaries who saw this coming, and he was afraid that people would not “remember” the same way.
Like any technology, writing brought its own set of discriminating biases. We value people who write great novels over those who tell great stories orally. We prize reading comprehension above all else in primary and secondary education. The victims of these biases are those who, for whatever reason, have difficulties reading visually.
