It's a view of memory as a static thing, a tape that gets filed away that will be exactly the same when you pull it out. Imagination is part of it too. We really have to be a lot more realistic about the limits of memory. So the discrepancies between your memoirs and your brother's are part of the truth. We have been accustomed to talking about computers using the human mind as metaphor, trying to make the computer like the mind but better, faster.
Computers are incapable of imagination and intuition.
We are incapable of the kind of recall the computer has. Thousands of people in this country are going through nightmares because of the faith that people can store memories completely intact and call them up again. And it's nonsense. Not in a systematic way. If I hear about something interesting I read it.
