Gurteen Knowledge Letter: Issue 304 - October 2025

Gurteen Knowledge Letter
Issue 304 – October 2025

Every so often, I come across someone in the field of conversation and dialogue who profoundly shapes my thinking, and I wish I had discovered their work sooner.

Recently, I came across Professor Rupert Wegerif, a Professor of Education at the University of Cambridge. His work demonstrates how dialogue can transform education and learning, broaden our thinking, and enhance our capacity for collective action.

This resonates strongly with my own work on Conversational Leadership. I love how he shows that dialogue isn’t just a way of teaching. It’s the ground of creativity and collective intelligence.

I’ve written a short profile of him, and his own reflections can be found on his Substack.

Just a reminder that I’ve recently started writing on Substack. It’s still early days, but I already have 19 posts up and around 60 subscribers.

Most of what I share is adapted from my blook, with some original essays as well. Check it out: https://davidgurteen.substack.com/

This is one of my favorite quotations:

Even if I knew that tomorrow the world would go to pieces, I would still plant my apple tree.

It’s often linked to Martin Luther, though there’s no evidence he actually said it. Still, the message holds: act with purpose even when the future looks bleak.

It was recently featured as a quote of the day, and one of my readers, John Erwin, pointed out that an older version is also found in the Islamic tradition. A hadith attributed to the Prophet Muhammad says:

“If the Final Hour comes while you have a sapling in your hand, and you can plant it before it comes, then plant it.”

Both sayings, from very different places and eras, share one clear principle:

There is dignity in doing something small and constructive, even when everything is falling apart.

Of course, the sapling will not take root. There will be no tomorrow. And yet we plant.

Now hold your head up, Mason
See America lies there
The morning tide has raised
The capes of Delaware

I’ve always loved songs that connect me to history. Al Stewart remains my favorite singer-songwriter of this genre. However, recently, I found myself listening to Mark Knopfler’s Sailing to Philadelphia, a song about Charles Mason and Jeremiah Dixon charting their Mason-Dixon line.

What struck me wasn’t only the history but the play of perception. We often speak of the world in ways that miss the deeper mechanics. The sun doesn’t rise or set; the Earth spins. The tide doesn’t raise the capes of Delaware; it raises the ship. It’s all about relative movement. And if you don’t recognize that you’re moving, it’s easy to mistake cause and effect.

This is not only a lesson in physics, but also a lesson in life, a reminder that we are always part of systems and currents larger than ourselves. If we forget that, we risk misreading what’s really shaping our world.

Some of the most interesting innovations don’t start with a clear plan. They begin as something else entirely. A feature or tool developed for one purpose ends up being used in a new and unexpected way. This is known as exaptation.

What interests me about exaptation is how it demonstrates that progress often arises from reinterpreting what’s already around us. Instead of building something new from scratch, we find new uses for existing things. Sometimes this happens by accident, and at other times, it occurs through a shift in perspective. This pattern is observed in biology, technology, and organizational life.

A recent example is how GPUs, developed initially for rendering graphics in video games, became central to the rise of artificial intelligence. Their architecture happened to be well-suited for training large neural networks, even though that was not the original intention. That kind of shift from one domain to another captures the spirit of exaptation.

I’ve been experimenting with ways to bring AI directly into my Conversational Leadership WordPress site. With just a few shortcodes, I can now turn text into audio, create videos, and even embed a ChatGPT panel for live interaction.

You do not need to be a skilled developer to do this. A basic understanding of WordPress and some simple PHP is enough. Claude wrote all of the code, and in my experience, it is better than ChatGPT at writing code.

Each shortcode took less than an hour to build. You can see the working examples on my site.

For almost 25 years, I've been sharing the Gurteen Knowledge Letter each month, and many of you have been reading it for five years or more. My Knowledge Café also reached a milestone, celebrating its 20th anniversary in September 2022.

If my work has made a difference to you, I'd be grateful if you could consider supporting it. A small monthly donation or any one-off contribution would greatly help cover some of my website hosting costs.

Thank you to the 50+ patrons who have already supported me - your generosity means a great deal.

If you're curious about how a more conversational approach might shift the way you work with others, whether in leading, learning, or collaborating, I offer one-to-one coaching tailored to your context.

We explore real challenges and possibilities through dialogue, helping you develop your own way of practicing Conversational Leadership in daily work.
