But what about human memory? It seems to shrink as computer "memory" expands. A Somali is taught to memorize her genealogy going back dozens of generations. I don't know any of my great grandfathers' first name. Do you know the first name of any of your great grandfathers?
How much reality do we carry inside of us, in our souls? What do we commit to memory? The ancient Greeks worried that inscription would erode memory. If it is written down, why internalize it? Primary orality requires vast memorization. Literacy requires less, yet does not necessarily debase memory. C.S. Lewis had a prodigious literary memory (due, I believe, to a photographic memory). Some rabbis shortly after the time of Jesus could consult the Hebrew Bible in written form, but memorized it in its entirety. Think of it. But is was easier for them. They didn't have television.
What have we memorized--accidentally or intentionally? Do you remember the five main characters of "Friends"? Do you know the five freedoms of the First Amendment? Which is more important to know? Do you know what's on your iPod? Do you know what's in your Bible (if you have one)? Have your tried to know, tried to remember?
Remember to remember.
