Here’s something I didn’t know: Friedrich Nietzsche used a typewriter. Many of those terse aphorisms and impenetrable reveries were banged out on an 1882 Malling-Hansen Writing Ball. And a friend of his at the time noticed a change in the German philosopher’s style as soon as he moved from longhand to type.

“Perhaps you will through this instrument even take to a new idiom,” the friend wrote. Nietzsche replied: “You are right. Our writing equipment takes part in the forming of our thoughts.”

Gulp. The technology writer Nicholas Carr, who pointed out this item of Nietzsche trivia in the new issue of The Atlantic, proceeded to make a more disturbing point. If a typewriter could do this to a mind as profound and powerful as Nietzsche’s, what on earth is Google now doing to us?

Are we fast losing the capacity to think deeply, calmly and seriously? Have we all succumbed to internet attention-deficit disorder? Or, to put it more directly: if you’re looking at a monitor right now, are you still reading this, or are you about to click on another link?

The astonishing benefits of Google are barely worth repeating. When I started to contribute this column, I used to keep a month’s worth of The New York Times stacked in my study. If I recalled an article or a report that I wanted to refer to, I’d spend a happy few minutes wrestling with frayed and yellowing paper, smudging myself with ink, and usually ended up reading an article that had nothing to do with my search.

I needed a good memory – even visually – to track my vague recollection down. I needed time. I needed to think a little before I began my research. Now all I do is right-click and type a few words. And all is instantly revealed.

I spend most of my day blogging – at a current rate of about 300 posts a week. I’m certainly not more stupid than I used to be; and I’m much, much better and more instantly informed.

However, the way in which I now think and write has subtly – or not so subtly – altered. I process information far more rapidly and seem able to absorb multiple sources of information simultaneously in ways that would have shocked my teenage self.

In researching a topic, or just browsing through the blogosphere, the mind leaps and jumps and vaults from one source to another. The mental multitasking – a factoid here, a YouTube there, a link over there, an e-mail, an instant message, a new PDF – is both mind-boggling when you look at it from a distance and yet perfectly natural when you’re in mid-blog.

When it comes to sitting down and actually reading a multiple-page print-out, or even, God help us, a book, however, my mind seizes for a moment. After a paragraph, I’m ready for a new link. But the prose in front of my nose stretches on.

I get antsy. I skim the footnotes for the quick info high that I’m used to. No good. I scan the acknowledgments, hoping for a name I recognise. I start again.

A few paragraphs later, I reach for the laptop. It’s not that I cannot find the time for real reading, for a leisurely absorption of argument or narrative. It’s more that my mind has been conditioned to resist it.

Is this a new way of thinking? And will it affect the way we read and write? If blogging is corrosive, the same could be said for Grand Theft Auto, texting and Facebook messaging, on which a younger generation is currently being reared. But the answer is surely yes – and in ways we do not yet fully understand. What we may be losing is quietness and depth in our literary and intellectual and spiritual lives.

The playwright Richard Foreman, cited by Carr, eulogised a culture he once felt at home in thus: “I come from a tradition of western culture, in which the ideal (my ideal) was the complex, dense and ‘cathedral-like’ structure of the highly educated and articulate personality – a man or woman who carried inside themselves a personally constructed and unique version of the entire heritage of the West.

“[Now] I see within us all (myself included) the replacement of complex inner density with a new kind of self – evolving under the pressure of information overload and the technology of the ‘instantly available’.”

The experience of reading only one good book for a while, and allowing its themes to resonate in the mind, is what we risk losing. When I was younger I would carry a single book around with me for days, letting its ideas splash around in my head, not forming an instant judgment (for or against) but allowing the book to sit for a while, as the rest of the world had its say – the countryside or pavement, the crowd or train carriage, the armchair or lunch counter. Sometimes, human beings need time to think things through, to allow themselves to entertain a thought before committing to it.

The white noise of the ever-faster information highway may, one fears, be preventing this. The still, small voice of calm that refreshes a civilisation may be in the process of being snuffed out by myriad distractions.

I don’t want to be fatalistic here. As Carr points out, previous innovations – writing itself, printing, radio, televi-sion – have all shifted the tone of our civilisation without destroying it. And the capacity of the web to retrieve the old and ancient and make them new and accessible again is a small miracle.

Right now, we may be maximally overwhelmed by all this accessible information – but the time may come when our mastery of the new world allows us to gain more perspective on it.

Here’s hoping. Shallowness, after all, does not necessarily preclude depth. We just have to find a new equilibrium between the two. We need to be both pond-skaters and scuba divers. We need to master the ability to access facts while reserving time and space to do something mean-ingful with them.

It is inevitable this will take our always-evolving species and ever-malleable brains a little time – and the Google era in a mass form is not even a decade old.

Some have suggested a web sabbath – a day or two in the week when we force ourselves not to read e-mails or post blogs or text messages; a break in order to think in the old way again: to look at human faces in the flesh rather than on a Facebook profile, to read a book rather than a blog, to pray rather than browse.

I think I’ll start with Nietzsche at some point. But right now I have a blog to fill.
