Re: writing technology
Come on now. There weren't even BIC pens then! You can't prove those books were better because they were written by hand, because those authors had no other choice.
I don't think having choice has anything to do with it. If anything, not having a choice for many thousands of years is one good reason why the brain and the hand work so well together when writing in longhand. They grew up together, so to speak. Writing in longhand and the human brain spent an awful lot of time playing with each other, and it made a difference.
And prove it absolutely, no. But there's some pretty convincing scientific evidence that writing in longhand is much better at stimulating the creative centers of the brain than is using a keyboard.
It isn't the tactile part of writing, it's the fact that we don't write letters, we draw them. In doing so, we're forced to use the same center of the brain that drawing uses. Brain studies have long since confirmed this. This means writing in longhand is automatically a left-brained, creative center activity.
The same studies have shown this doesn't happen with a computer.
Typewriters, on the other hand, while not automatically using the drawing center of the brain, do induce right brained activity much better than computers. The reason here isn't as clear, but it does happen, quite possible because of the loud, rythmic noise theh typewriter makes.
There are many reasons why the overall quality of writing has decreased so rapidly since word processors have become common, but I think the word processor itself is at least partly responsible.
