Round and round

Cycles are an easily identifiable feature of universal human experience. Arguments go ’round in circles’. Efforts to change get caught in vicious circles or Catch 22s. Buddhism has its Wheel of Samsara (or ‘Wheel of Life’), in which craving leads to frustration and then more craving. Various social sciences identify various cycles: the economic cycle, the political cycle, the cycle of addiction, the cycle of violence, the cycle of poverty and degradation, and so on. What do these cycles have in common? Are they inescapable?

One interpretation I want to resist from the start is the belief that these cycles are inescapable (or alternatively, only escapable through some miraculous supernatural cause) because ‘natural’. The cycles I’ve mentioned so far all depend on the human brain, so we have no reason to conflate them with other sorts of cycle that are entirely (rather than debatably) beyond human control – such as eco-cycles, planetary cycles, or the cycle of birth and death. Though they may share some formal features with other kinds of cycles, the kinds of cycles I want to focus on here are within the sphere of human judgement: and that’s a sphere in which the extent of our responsibility remains perpetually vague and unresolved.

What the cycles within that sphere seem to have in common is their relationship to looped synaptic tracks in the brain. Broadly, we can see our feedback loops as leading from the older ‘reptilian’ lower brain, where our basic motives arise, to the pre-frontal cortex in the front of our brains, where we conceptualise and contextualise in a more distinctively human fashion. But this understanding of the situation then gives rise to new motives, looping us back to the back of the brain. We ‘go round in circles’ when we are in the habit of following certain entrenched synaptic tracks, in which certain kinds of desires give rise to certain kinds of beliefs, that then reinforce the desires and again reinforce the beliefs.  For example, Marc Lewis shows this process in the brain of an addict in his book The Biology of Desire, reviewed here. As Lewis points out, it’s not only drug addicts that go through such feedback loops, but to some extent all of us.

We also go through such cycles over a shorter period of time when we ‘ruminate’: going through a proliferating cycle of thoughts that are usually motivated by obsession or anxiety. If you keep thinking the same thoughts over and over again and can’t get to sleep, or can’t focus on work or meditation, you are probably caught in a positive feedback loop.

Positive feedback loops are the means by which we can set up good habits as well as bad ones, and as long as we are in a stable environment in which those habits are helpful, relying on them isn’t too much of a problem. However, if we want to be able to adapt to ever-changing new circumstances, we need to be able to move out of unhelpful positive feedback loops of this kind. Where they become conceptualised in the left pre-frontal cortex, these loops are the basis of confirmation bias: we tend to just seek out evidence that fits the beliefs we already have, rather than challenging those beliefs – and this tendency is the basis of all sorts of other errors.A positive feedback loop

We have good evidence from experience that we are able to move out of such positive feedback loops, by responding to new experiences that challenge our beliefs, and thus adapting our beliefs to fit new circumstances. Instead of a positive feedback loop in which an old habit is reinforced, this is then a negative feedback loop in which learning and adjustment can take place. However stuck in our ways we may be, we have all done this lots of times in the past, especially as children. The human brain retains its plasticity well into old age – and thus we are always capable of changing our beliefs, even if we find the process uncomfortable. To get out of a circular argument, then, or even an addiction or an economic cycle or a cycle of violence, we just need to be willing to learn how to do things differently.

I sometimes think that if this wasn’t called the Middle Way Society, it could be called the ‘Negative Feedback Loop Society’. It’s that basic to what the Middle Way is about. For the extremes avoided by the Middle Way are rigid or absolutised beliefs of a kind that resist change and maintain themselves only in the context of positive feedback loops. In the Middle Way, or as Ed Catmull memorably calls it the ‘messy middle’, we are able to be creative, to switch strategies, to adapt.A negative feedback loop

Some people are confused by the labels, assuming that a ‘Negative Feedback Loop’ must be bad because it’s negative. But it’s negative only in the sense that it challenges and catalyses change – not necessarily emotionally or logically negative. Similarly, there’s nothing necessarily ‘positive’ in an emotional sense about positive feedback loops: indeed the repression that they often bring with them is likely to stifle any sense of joyfulness and replace it with alienation and boredom in which the energy of possible alternatives is dimly felt but nevertheless denied.

In some formulations of Buddhism (such as that of Sangharakshita), the Wheel of Samsara (which may be interpreted along the lines of such an addictive cycle) is accompanied by a Spiral. A spiral gives graphic expression to the idea that we might continue to go round and round to some degree whilst lifting out of those habits in other respects, and is thus one way of symbolically representing the process of moving out of positive feedback loops and into negative ones. However, the Spiral is often represented as though it was a single absolute path culminating in the transcendent point of nirvana, and on that interpretation, at least, it seems to be incompatible with the Middle Way. Negative feedback loops are a different pattern of judgement, but one that we might find in the thick of a complex pattern of positive feedback loops, and it is the nature of the judgement that is important rather than the ultimate destination.Wheel of samsara

Positive feedback loops, like samsara in Buddhism, should not be seen as intrinsically bad, but they are limited, and a set of beliefs that rigidly limits us to such loops does then become morally inferior when compared to alternatives that allow us to adapt to a wider range of conditions. We do not need to deduce this from a supposed standpoint of nirvana, or any other supposed absolute beyond experience. It should be clear to us as long as we are willing to simply compare a relatively flexible standpoint to a relatively inflexible one.

A Tale of Two Metaphors

All our thinking depends on metaphors. The work of George Lakoff and Mark Johnson explains the way in which we build our cognitive models on a particular metaphor, which is mapped onto a physical experience schematised into our neural connections. For example, the picture here illustrates an old Platonic cognitive model for the mind or soul in relation to the body: the body as a cage in which the otherwise free mind is constrained. It never seemed to occur to anyone using this metaphor that our experience of being imprisoned is a physical one, and we’d need a body to even experience what it meant to be released from a cage. Nevertheless, a good deal of Plato’s philosophy depends on this metaphor.Byzantine_Metaphor_For_The_Soul_and_Death

Plato’s basic mistake here is one that we are all prone to: of adopting just one basic metaphor and assuming that it is the final word. A ‘stuck’ metaphor is what one might otherwise refer to as a metaphysical belief. As long as we take them provisionally, however, metaphors are also the only way in which we can build up an understanding of anything. Very often, if you’re trying to explain something abstract, people only ‘get it’ when you use a metaphor. That means they’ve found a way of making it meaningful in relation to their wider bodily experience. Metaphors tend to come in connected groups, too (Plato didn’t just use the one about the soul in a cage, but also the soul as a charioteer, and many others). We can reinforce one metaphor with others, or challenge one metaphor with a different one. Perhaps the major difference between creative philosophy and mere analysis is that creative philosophy works with metaphors, pulling them together, testing out compatibility and incompatibility, whilst mere analysis just works away doggedly within one cognitive model on the assumption that it is right.

One crucial point in Middle Way Philosophy is that a belief is not ‘merely relative’ because it’s dependent on a metaphor, any more than it’s absolutely true because it’s hit the right metaphor. Some metaphors provide more adequate models for interpreting conditions than others do. The better ones can link together a great many other metaphors, as well as explaining a wide range of experiences. We can stretch metaphors to make them bigger by linking them with others, and the more provisionally we are holding the metaphor, the easier it is to do this.

So, here is a challenge to Middle Way Philosophy that I’ve been reflecting on. There is one key metaphor of the Middle Way, which relates to our experiences of following a path and of balancing: but is this metaphor being relied on too much? How can this metaphor be provisional when it is also so all-encompassing?

I have two linked responses to these linked questions. One is that Middle Way Philosophy doesn’t just depend on the metaphor of the Middle Way, but also that of integration. Another is that the bigger and stretchier a metaphor is, the more provisional it is. Middle Way Philosophy is not an ultimate explanation, but at the same time it is the kind of explanation that becomes more adequate the more it encompasses.

Firstly, then, the metaphor of the Middle Way and that of integration. These two models offer rather different models of thinking, but they are still linked. Integration is basically the Middle Way inside out. Whilst the Middle Way is a negative model that takes our motivation for granted and just tells us that there are metaphysical traps to avoid on either side, integration takes the things on each side more positively, suggests that they do themselves have motivating power, and that both the energy and the metaphors on either side can be positively incorporated into a whole The two metaphors complement each other enormously and yet remain compatible. Without the rigour of the Middle Way, integration models can get rather naïve and new-agey; but without integration, the Middle Way can get rather dry and negative.

Would it be possible to combine the two metaphors? Well, here’s an attempt. Suppose you’re captain of a ship heading through a dangerous strait between two rocks. Some of your passengers want to go straight on, but others want to pick up friends from the rocks on either side. So, you do head straight on, but not before you have picked up further passengers and rescued them from the rocks on either side. This requires both courage and skill. Once you’ve picked up all the passengers from both sides, everyone can be united in urging you onwards through the rest of the strait.

This combination of metaphors illustrates the way that even metaphors that at first seem separate can be combined and stretched. That’s one reason why I’m interested in studying even religions that seem to have a heavy metaphysical emphasis, like Islam, and, metaphorically speaking, picking up the passengers from that rock too. I want to argue that the more a given metaphor can explain the strengths of others in that way, without getting sucked into the assumption that any one metaphor is final, the more justified confidence we can have in that metaphor. If a given approach can offer responses that account for the successes other metaphorical approaches, rather than simply rejecting them as wholly wrong, it provides the basis of a bigger and more adequate metaphor.

I think Middle Way Philosophy is like this. That’s one of the reasons why it is so all-encompassing: it needs to be able to account for the insights available from different traditions and from different specialisms. However broad it is, though, to remain provisional it must be fallible. If someone else can come up with a better theory that explains all the things Middle Way Philosophy explains and does all the things it does: explaining the nature of objectivity, providing a justifiable ethics, resolving the absolutism/ relativism split, combining theory with practice, facts with values, the religious and the secular, art and science, whilst taking into account the scientific evidence for things like embodied meaning, the splits in the brain and our cognitive biases, then I will drop this theory and come and help them on theirs. Theories based on particular metaphors can be superseded – but they have to be superseded in doing the job that they set out to do, explaining both the successes and failures of the theory to be superseded.
