Once upon a time, there was nothing to do with thoughts except remember them. There was no alphabet to transcribe them in, no paper to set them down upon. Anything that had to be preserved had to be preserved in memory. Any story that would be retold, any idea that would be transmitted, any piece of information that would be conveyed, first had to be remembered.
Today it often seems we remember very little. When I wake up, the first thing I do is check my day planner, which remembers my schedule so that I don’t have to. When I climb into my car, I enter my destination into a GPS device, whose spatial memory supplants my own. When I sit down to work, I hit the play button on a digital voice recorder or open up a notebook that holds the contents of my interviews. I have photographs to store the images I want to remember, books to store knowledge, and now, thanks to Google, I rarely have to remember anything more than the right set of search terms to access humankind’s collective memory. Growing up, in the days when you still had to punch seven buttons, or turn a clunky rotary dial, to make a telephone call, I could recall the numbers of all my close friends and family. Today, I’m not sure if I know more than four phone numbers by heart. And that’s probably more than most. According to a survey conducted in 2007 by a neuropsychologist at Trinity College Dublin, fully a third of Brits under the age of thirty can’t remember even their own home land line number without pulling it up on their handsets. The same survey found that 30 percent of adults can’t remember the birthdays of more than three immediate family members. Our gadgets have eliminated the need to remember such things anymore.
Forgotten phone numbers and birthdays represent minor erosions of our everyday memory, but they are part of a much larger story of how we’ve supplanted our own natural memory with a vast superstructure of technological crutches—from the alphabet to the BlackBerry. These technologies of storing information outside our minds have helped make our modern world possible, but they’ve also changed how we think and how we use our brains.
...
In Plato’s Phaedrus, Socrates describes how the Egyptian god Theuth, inventor of writing, came to Thamus, the king of Egypt, and offered to bestow his wonderful invention upon the Egyptian people. “Here is a branch of learning that will ... improve their memories,” Theuth said to the Egyptian king. “My discovery provides a recipe for both memory and wisdom.” But Thamus was reluctant to accept the gift. “If men learn this, it will implant forgetfulness in their souls,” he told the god. “They will cease to exercise their memory and become forgetful; they will rely on that which is written, calling things to remembrance no longer from within themselves, but by means of external marks. What you have discovered is a recipe not for memory, but for reminding. And it is no true wisdom that you offer your disciples, but only its semblance, for by telling them of many things without teaching them anything, you will make them seem to know much, while for the most part they will know nothing. And as men filled not with wisdom but with the conceit of wisdom, they will be a burden to their fellow-men.”
Socrates goes on to disparage the idea of passing on his own knowledge through writing, saying it would be “singularly simple-minded to believe that written words can do anything more than remind one of what one already knows.” Writing, for Socrates, could never be anything more than a cue for memory—a way of calling to mind information already in one’s head. Socrates feared that writing would lead the culture down a treacherous path toward intellectual and moral decay, because even while the quantity of knowledge available to people might increase, they themselves would come to resemble empty vessels. I wonder if Socrates would have appreciated the flagrant irony: It’s only because his pupils Plato and Xenophon put his disdain for the written word into written words that we have any knowledge of it today.
Socrates lived in the fifth century B.C., at a time when writing was ascendant in Greece, and his own views were already becoming antiquated. Why was he so put off by the idea of putting pen to paper? Securing memories on the page would seem to be an immensely superior way of retaining knowledge compared to trying to hold it in the brain. The brain is always making mistakes, forgetting, misremembering. Writing is how we overcome those essential biological constraints. It allows our memories to be pulled out of the fallible wetware of the brain and secured on the less fallible page, where they can be made permanent and (one sometimes hopes) disseminated far, wide, and across time. Writing allows ideas to be passed across generations, without fear of the kind of natural mutation that is necessarily a part of oral traditions.
To understand why memory was so important in the world of Socrates, we have to understand something about the evolution of writing, and how different early books were in both form and function. We have to go back to an age before printing, before indexes and tables of contents, before the codex parceled texts into pages and bound them at the edge, before punctuation marks, before lowercase letters, even before there were spaces between words.
Today we write things down precisely so we don’t have to hold them in our memories. But through at least the late Middle Ages, books served not as replacements for memory, but rather as memory aids. As Thomas Aquinas put it, “Things are written down in material books to help the memory.” One read in order to remember, and books were the best available tools for impressing information into the mind. In fact, manuscripts were often copied for no reason other than to help their copier memorize them.
In the time of Socrates, Greek texts were written on long, continuous scrolls—some stretching up to sixty feet—pasted together from sheets of pressed papyrus reeds imported from the Nile Delta. These texts were cumbersome to read, and even more cumbersome to write. It would be tough to invent a less user-friendly way of accessing information. In fact, it wasn’t until about 200 B.C. that the most basic punctuation marks were invented by Aristophanes of Byzantium, the director of the Library of Alexandria, and all they consisted of was a single dot at either the bottom, middle, or top of the line letting readers know how long to pause between sentences. Instead, words ran together in an unending stream of capital letters known as scriptio continua , broken up by neither spaces nor punctuation. Words that started on one line would spill over onto the next without even a hyphen.
