From Seymour Papert in New Theories for New Learnings via The Daily Papert.:

“Imagine (if you can) that we lived in a world without writing-and, of course, without pencils, pens and books. Then one day, somebody invents writing and the pencil, and people say, “Wow, this would be great for education. Let’s give these things to all the children and teach them to write.” So then somebody else says, “Hey, wait a minute. You can’t just do that. You can’t just give every child a pencil. You’d better start by doing some rigorous experiments on a small scale. So, we’ll ‘put one pencil in a classroom and we’ll see what happens. If great things happen, we’ll put two pencils in a classroom, and if greater things happen, then we’ll put in more…” (Papert, S. 1984.)

‘Nuff said.
