"Consider the story of the Egyptian god Thoth as it was told by Plato. Thoth has invented writing and proudly offers it as a gift to the king of Egypt, declaring it "an elixir of memory and wisdom". But the king is horrified, and tells him: "This invention will induce forgetfulness in the souls of those who have learned it, because they will not need to exercise their memories, being able to rely on what is written…rather than, from within, their own unaided powers to call things to mind. So it's not a remedy for memory, but for reminding, that you have discovered. And as for wisdom, you are equipping your pupils with only a semblance of it, not with truth."

That was written 2,400 years ago, and Lloyd pointed out that similar arguments about inevitable damage to human thinking and memory attended the arrival of printing in the 15th century AD. We seem to have survived both shocks with our capacity for general knowledge intact, indeed enhanced. That puts modern concerns into perspective. "
