A tree falls alone in the forest. It makes no sound, because there is no one to hear it. There can be no sound without the ear to hear, no scent without the nose to smell, and no colour without the eye to see. Nor can any of these things be apprehended, without the brain to reflect them as qualities upon the dark mirror of the mind, thereby creating the human experience of the world.
The common-sense story of the world says there is a universe of material objects – galaxies, stars, chairs, tables, teapots, atoms – all of them occupying space, and enduring for a time, in time. We are objects, too, but, unlike teapots, we have senses plugged into a material brain which, together, and by an unknown process, provide us with a mental image of reality. They also produce this thing we call “mind”, which enables us to be self-aware, to be conscious of ourselves.
This is the orthodox “materialist” story, born of the scientific revolution, and the consequent death of all the gods. It makes sense to us, because we all “seem” to share the same world. The world doesn’t “seem” to depend on our presence. The moon is still there when we are not looking at it. The ocean tides still follow a regular, and calculable pattern that is not of our imagining. And when we experience things in the world, our brains show measurable activity. All of this suggests the material world-model, and our separate subjective mental awareness of it, is the correct way of viewing things. It is the right story to tell, and to believe in. It is the right story to tell our children.
But we cannot explain how the material brain gives rise to the quality of feelings aroused by a sunset, or by falling in love, or the pleasure we take in the taste of things, or the scent of a rose, or in the ways music can move us, or even the perception of our favourite colour. These are all qualities, and are unresponsive to mathematical analysis. Mathematics favours the material. Materials have length, mass, time, temperature, current. But there is nothing about them that explains how they create the mental experience of sensed reality. The material universe exists materially, but our experience of it does not.
This, then, is the often told story of the world, but it has a gaping hole in the middle of the plot, because it does not explain the nature of our selves. And those writing this story are now so frustrated by the stubbornly inexplicable nature of “mind” and “consciousness”, they conclude it must be an illusion, that it is generated by an emergent property of the brain. Thus ends our journey into the material realm, with the conclusion that, although we think we exist, actually we do not. We have already eliminated the gods. Now we have eliminated ourselves.
So, a tree falls alone in the forest, it makes no sound. This is confusing, because we mistakenly believe the material world itself possesses qualities like colour, taste and sound – that the greenness of the grass, the scent of the rose, the sweetness of the musical note, are in themselves physical, and “out there”. But they aren’t. That’s not what the material world story is saying at all.
What is the sound of the falling tree? In material terms, it is a wave of pressure. Quantities of pressure are called Pascals. Pascals are Newtons per square meter, which is a mass, multiplied by gravitational acceleration, which is meters per second, per second. Add it all up, and what have we, got? We have a mathematical statement of mass, length and time. What we do not have are timbre, rush or roar. What is “roar”? What is the mass-length-time of a roar, of a rush, of a timbre? Materially, there is no answer. Only the mind knows these things. What we don’t know is how the mind knows them.
What can we say with certainty about the mind? Let’s ask the materialists: It correlates with brain activity, they say. This is reasonable. But by the same reasoning, one would expect the mental experience to increase in proportion to the measured activity. A brain, lit up and buzzing with neuronal action, would be experiencing a greater degree of mental activity than one that is not. Let’s go further and say an inactive brain should give rise to no experience whatsoever. Such a brain would be unconscious, or even dead. However, there is persuasive evidence that the opposite is the case.
A dramatic reduction in recorded brain function correlates with the most profound expansion of the subjective mental experience. Two areas of research confirm this: near death studies, and the experience of psychedelics. In both cases, there is a diminution of the measured brain function, yet a corresponding explosion of subjective mental awareness. This awareness is not chaotic, as in an hallucination, nor is it passive, as in ordinary dreaming. It is lucid, coherent, memorable and profoundly meaningful to the individual. What does this suggest? It’s hard to say for certain, but there is the sense of a door opening.
A normally functioning brain gives rise to our experience of the world, but that’s not all. It also seems to be restricting access to a transcendent experience of being, one in which we seem to exist as a kind of psychical alter, in a realm of pure mind. This would otherwise overwhelm us for our day-to-day purposes, so there is a narrowing of the mental experience, one that is so difficult to escape, we conclude, quite reasonably, the material world is all there is. The transcendent experience however reveals that by far the greater sense of our being exists in a purely non-material sense, transcending the apparently material dimension. Is it then too far a leap to say that, in the normally parsimonious nature of the universe, there may not be a material reality, as we think of it, at all?
I don’t know, the answer to that question, but I’ve spent a lot of time thinking about it, and I sense the story of the world is not yet done, that a fresh and extraordinary chapter is beginning. With luck, it’ll patch up that glaring plot hole, and arrive at the conclusion we might exist after all, just not in the way we’ve come to think we do. It’s a curious concept, a little unsettling, just like the idea that when a tree falls alone in the forest, it makes no sound.
