That books, a commodity little changed since Caxton's day, should have turned out to be the trailblazers of retailing on the internet is one of the stranger cultural ironies of our time.

The cyborg is now the ideal to which all our most advanced technology is tending.

Nobody, 20 years ago, forecast the Internet.

On the maps provided by science, we find everything except ourselves.

Information is the new atom or electron, the fundamental building block of the universe ... We now see the world as entirely made of information: it's bits all the way down.

Of course, this is not proof they are not true, but it does provide a persuasive context for a simple psychosocial explanation.

Scientists themselves are of surprisingly little help. They find it difficult to talk of what they do because they tend to assume detailed knowledge is required for generalities to be understood. They find it hard to grasp the concept of the meaning of their work, assuming this to be a debate that takes place at a lower level than the specialized discussions with their colleagues. When they do generalize, - or "popularize" as it is usually called with a noticeable degree of contempt - they tend to reveal a startling philosophical naiveté.
