We have a large mulberry tree growing in the middle of the garden. It’s huge leaves make a perfect canopy to shade you from the glare of the summer sun.

In the autumn they fall massively giving me ample opportunity to enjoy a bit of “rake-y” – the meditative experience of raking up the fallen leaves. I find that deeply satisfying!

In the winter time the tree is bare, all branches and twigs but its shape against the moon at night is entrancing.

Now in the Spring the new leaves are starting to grow. The first of them began to emerge last week. Look at this one! I could have picked one of several dozen like this but I stopped to photograph this one.

It astonishes me.

Out of the end of this stick of a twig first a swelling green bud appears, then these leaves start to unfold themselves. Really they are so tiny compared to how they will look when fully grown. The biggest leaves will be larger than your hand. But for now, this emerging leaf is so small it’s only just begun to acquire the recognisable shape of a leaf.

Look at the colour of it in the sunshine! That light, bright green, somehow just shouts “I’m alive!”

As I looked at it I remembered the time Richard Feynman asked the question “Where do trees come from?” and shocked the listener by answering “They come from the air”. Here’s an article which includes the video of him talking about this very subject. He says most people would answer “They come from the soil” but he says it is more correct to say they come from the air, because they are made mainly of carbon which they capture from carbon dioxide which is in the air, and from water which comes directly from the sky as rain, or through the soil after it’s fallen from the sky.

Isn’t that an astonishing thought? We humans certainly can’t do that. We can’t make solid massive forms like trees out of the thin air.

I was eating some berries at lunch time – strawberries, raspberries and blueberries.

Stopping to take a closer look…….look at the shape of a star on this blueberry.

Well, it turns out this is pretty standard. All blueberries have this element of their appearance.

Have you noticed that before?

Have you seen that little star there before you pop the berry into your mouth?

Noticing is one of the lessons I’ve learned yet again from this little ordinary, everyday experience, but there’s something else here.

That something else for me is a reminder that we are “all made of star stuff”. From the origins of the universe, the time of the energies before the formation of hydrogen and helium, to the evolution of stars, those great powerhouses of fusion producing the first larger elements, magnesium, lithium, carbon….all the way up the Periodic Table to Iron….to the next great leap – the supernovae. As the supernovae exploded they produced all the other known elements of the universe.

From our Sun, to our Solar System, to our precious, tiny Earth, all emerged from these first elements. That carbon, that oxygen, that hydrogen, all the elements you might find in one little blueberry….it all came from the stars.

As best we know, from the beginning of our planet Earth, not a single new natural element has appeared. All of us, from blueberries, to you and me, are made from those original atoms, created by aeons of fusion and fission, of cycles of combining together, and cycles of blowing apart.

Takes my breath away….

And you know what? The blueberries taste great. I enjoyed combining their star stuff into mine…….

Last November I was invited to address the Faculty of Homeopathy at their Congress in Belfast. I prepared a talk entitled “Images of Health. Pictures and stories” based around some of my own photographs and covering the key principles of health which guided me through my career as a doctor.

Here’s the video of that talk. I hope you enjoy it, find it interesting, or even inspiring. (by the way, if Google pops up any ads along the bottom of the video, just click the “x” box to make them go away 😉 )

I wrote a book to accompany this talk. It’s called “Escape to Reality” and I’ve published it (so far) only as a Kindle e-book. You can find it on Amazon.

Do you ever look outside and see a grey sky and rain and think, shame, “it’s not a nice day”? I do.

But the other day when I caught myself saying that I thought, hang on, when the rain falls on the flowers it makes them extra specially beautiful, I think I’ll go out and take some photos.

Here are some of my favourite ones.

I think the rain magnifies their beauty, not making them similar in any way, but highlighting how unique each and every one is.

I also love the image of the single rain drop. It’s like a jewel. I’m never finished finding water extraordinarily wonderful. And, in a certain sense, water is never finished finding us extraordinarily wonderful either, is it?

Here’s to the sparkling beauty of uniqueness.

Here’s to the magic of water.

Look at the skeleton of this beautiful fish. The intricate and delicate structure of the bones is a stunning demonstration of the nature of networks. We can see the whole skeleton is made up from two simple elements, nodes and connectors. Whether we zoom in to study just one group, or out to look at the larger regions we see a variety of different patterns based on these two simple elements.

If you start at any point on this skeleton you’ll be able to trace a path to any other point without ending up down some disconnected cul de sac. In other words every single point is connected to every other one….either in simple one or two step connections, or through an almost infinite variety of pathways across the whole structure.

This is one of the most fundamental patterns at the heart of reality – networks of nodes and connectors.

You can see the same design in all forms of life, especially in multicellular organisms, all kinds of plants, animals and human beings.

Networks of nodes and connectors are the essential fabric of the universe.

Two of the best books I know about this phenomenon are Linked by Barabasi, and Connected by Nicholas Christakis and James Fowler. I recommend them both. They show how this apparently simple structure builds up into the most complex of phenomena, from individual organisms, to social groups and whole ecosystems.

Once you see things this way you can’t help but see connections everywhere. It’s the science which demonstrates the limitations of reductionism and abolishes the notion of atomisation.

As I was opening the shutters yesterday morning I caught sight of some swirls of mist lying amongst the vines towards the next village. I took a few photos. Here’s one of my favourite ones. It pleases me. Enormously. There’s an entrancing beauty to it. And it’s one of those photos which stimulates all kinds of thoughts for me.

I look at this and I think of two of the fundamental forces of the universe – the ones which Thomas Berry called “wildness” and “discipline”. The large tree in the centre of the image grows wild. It grows naturally and it spreads out above and below ground creating this ever branching structure which looks like its reaching out to the world. It looks like it’s stretching upwards and outwards to feel the sky and the moist air. In front of it are rows and rows of vines, trained and pruned by human hand, disciplined to grow along the wires. The vines form a complex web of life. As I look at them now it’s hard to discern where one plant stops and the next one begins.

When I think of these two forces, I think of the two hemispheres of the brain, each with its distinctive style of engaging with the world. The right hemisphere exploring, seeking the new, making connections. The left hemisphere exploiting, grasping, structuring. Iain McGilchrist writes in “The Divided Brain“, that the right hemisphere characteristically seeks to care, it seeks to engage with “the other” empathically. The left hemisphere seeks to control, seeking to deal with “the other” by categorising, labelling and separating.

How we see these forces at work in the world today!

Peter Brabeck-Letmathe, the outgoing chairman of Nestlé’s intention is for Nestlé to develop food scientifically – synthetic food which will be better than “natural food”. He rejects the notion that food grown in the ground is best for us. He says

Nature is not good to human beings. Nature would kill human beings. The reason why homo sapiens have become what we are is because we learned to overcome nature.

What do you think when you read this?

Is “Nature not good to human beings”? Does Nature seek to “kill human beings”?

I was pretty astonished at this claim because I think human beings are part of Nature, not something outside of “it”. If we want to learn what’s good for us my own feeling is that we should look to the rest of Nature. As Idriss Aberkane says of “biomimicry”, Nature is a library, a source of knowledge, not a source of repository of fuel to burn.

So where does this idea that Nature is trying to kill us come from?

Well, as chance would have it I read an interview with the French philosopher, Michel Onfray, at the weekend, and he mentioned the definition of life given by Bichat, the physiologist

Life is the sum of the forces which resist death

That’s an interesting definition of life – life is resistance. Is death constantly attacking life? I think that’s a pretty miserable and negative understanding of life. But I think it might come from the notion of entropy. You know about entropy? Entropy is “the gradual decline into disorder”. The second law of thermodynamics states “entropy always increases over time”. You can probably see how this observation can lead you to think that we are only alive as long as we resist death, disorder, and decline. But is that enough to lead you to conclude that Nature is trying to kill us?

It seems to me that this entropic force in the universe is only one of the major forces at play. What Thomas Berry referred to as “wildness” is another way of thinking about this force. It’s the chaotic force. If this was all there was, or if this was the dominant force, what would the universe look like? Would there be stars? Would there be galaxies of stars moving together? Would stars have planets? Would there be any complex living organisms? How could there be? There is a second force. One Thomas Berry calls “discipline”. It’s the ordering principle, the structuring principle, which contains, limits and holds together. But what if that was the only force in the universe? What would the universe look like then? Would it be any more than a dense ball of energy? Would it be expanding? Would it show diversity? Or would whatever existed by “more of the same”?

I think there is a third force at work in this universe, because it seems to me, without it, there is a tendency for the first two forces to cancel each other out, or for there to be a significant tendency towards either chaos or uniformity.

That third force is creativity. The creative force is a force of integration – it integrates the two forces of wildness and discipline to produce astonishing levels of complexity. Look at the history of the universe. Is it a history of endless decline and degeneration, or one of stasis and constriction? Or is it a story of ever increasing complexity and diversity?

It’s this latter, isn’t it? The universe is on a course of increasing complexity. We humans, with our bodies, our brains and our consciousness, are the most complex phenomena the universe has produced so far. But we haven’t been about for very long.


(the cosmic calendar)

The universe is on a course of increasing diversity. Not just the rich diversity of species and life forms on planet Earth, but in the diversity of unique human beings. Not one of us ever repeated. No single experience of a whole life ever duplicated.

So is Nature a threat to us? Or is Nature a manifestation of the creative force of the universe?

I’m opting for the latter view. And I’m going to continue to enjoy the fruits of that rich creative diversity, just like you see in my photo at the start of this post. I won’t be swapping “real food” for synthesised, chemically “enhanced” stuff any time soon!
