The Human Mind Isn't Very Good at Memory

David Frum: Writing is this great invention because it kind of extends human memory when we're thinking. On the other hand, Andrew's Erickson trained a couple guys to memorize many, many digits and found that they were able to go way beyond what you would normally think. And then if we think back to generations and generations ago, like the Torah, the Jewish Bible, was just passed from generation to generation orally. So that does suggest that the human mind is certainly capable of engaging with that component much more than we do now.
