It's a strange fact that the better we have got at manipulating the world, the less meaning we seem to find in it. Why would that be? I am often asked to speak because of a book I wrote about the structure of the brain, addressing the vexed topic of the difference between the brain hemispheres. I am not going to speak about it today – there isn’t nearly enough time – but its thesis will inform what I have to say. Because it has to do with meaning. In brief the difference between the brain hemispheres lies not, as if they were machines, in what they do, but, as befits a part of a person, in the way they do it. Forget what you have been told. Each is involved in language, reason, visual imagery, emotion, imagination and the rest – but in a consistently different way. And this has to do with survival. Every creature needs to solve a conundrum: how to eat and stay alive. For in order to eat it needs to pay a very particular type of attention: narrow-beam, fixed on its target and blind to everything else, precise, enabling a grasp that is swift and accurate. But if it is not to become someone else’s lunch while getting its own, it needs at the very same time to pay the exact opposite type of attention: a broad, sustained vigilance, maximally alert to whatever it may find, without preconception, be it friend or foe. So difficult is this for one consciousness to achieve, that every known animal – fish, amphibian, reptile, bird or mammal – has solved the problem by having two ‘brains’, closely connected, but also remarkably capable of independence: hence the two hemispheres. It is the left hemisphere that has developed the capacity for very narrow, sharply-focussed attention, and the right hemisphere that has developed the capacity to see the whole picture. Once again may I emphasise: the difference is not between logic and emotion, or between being down to earth and airy fairy, or male and female, or any other of these daft generalisations. It is about attention. And everything flows from that. Putting it very simply, the left hemisphere sees a world of things: fragments that are familiar, precise, inert, inanimate, isolated, disconnected from us, and there for us to manipulate. The right hemisphere by contrast sees a world of relationships: living, changing, infinitely interconnected elements in a continuous flow from which they can never be isolated, any more than they can from us: a world that we can understand and has meaning. Things in themselves have no meaning: meaning comes from relationship. Everything that exists is made up of the same set of particles – what makes the difference between you, a tree, and a boiled egg is just the relationship of the particles to one another. The meaning comes not from the particles, the bits, which are in themselves undifferentiated, meaningless, but from the relationship between them. The most moving piece of music you ever heard is just a collection of meaningless notes from one point of view: from the other the meaning arises from the relationship, which makes the melody, the harmony and so on. And so it is with everything in life we value: its meaning comes from relationship – with your loved ones, the place where you belong, your friends, the natural world itself, a work of art, a poem or a symphony. It all lies in relationships, not in things themselves. When we see the world with targeted, narrow beam attention it is just a meaningless heap of things to be grabbed. When we see the world as a whole with broad open attention its meaning
