Exploring the Divided Brain – Where can we go for truth?

21st August 2016 am – a 4 day course with Iain McGilchrist. Day 3 (am)

This is the fifth in a series of posts in which I am sharing the notes I took whilst attending a 4 day course- Exploring the Divided Brain- run by Field & Field and featuring Iain McGilchrist.

Here are the links to my previous posts:

Where can we go for truth? (Some thoughts about the question of what constitutes truth)

I think this may have been a repeat of the Laing Lecture that Iain gave earlier in the year at Regent College in Vancouver. It bore the same title. I can’t find a video recording of that lecture, but the introductory text on the web page  is …

How do we think about truth? Where do we go to find it? While science and reason have undeniable power to disclose many aspects of reality, they do not reveal everything. In this lecture, Iain McGilchrist explains why we cannot rely only on the reports of science or the power of rational argument and demonstrates that it is both unscientific and irrational to do so.

… and these were the same topics and questions that Iain covered in our session.

How do we think about truth? Iain’s answer was that if there is a God (and for him God is a process, an eternal becoming) then how can we stop ourselves thinking about truth, but he believes there is no definitive answer to this question.

On reflection I wonder if underpinning all Iain’s work is a search for an understanding of the meaning of ‘God’ (and here I use the word ‘God’ for want of an alternative). As he writes on p.150 of the Master and his Emissary, ‘Things are not whatever we care to make them. There is something that exists apart from our own minds’… and on p.151, he writes, ‘[Truth]is an act, a journey, not a thing. It has degrees. It is found by removing things, rather than putting things together.’

For the left hemisphere where understanding is built up from parts, there is objective evidence for truth, but for the right hemisphere, truth is derived from the whole and can only ever be provisional (p.142, The Master and his Emissary).

Where shall we go for truth? Iain suggested that we go to the beauty and awe-inspiring magic of the non-academic, non-religious natural world, where opposites tend to coincide as much as disperse and where intuition and insight is more directly compelling than reason. Reason, he said, is the endless paperwork of the mind, but for truth uncertainty is essential.

We cannot go to science for truth. Science cannot fulfil the role of purveyor of truth. Good science is always aware of its limitations, but science cannot discover the purpose of life nor tell us about God’s nature or existence and science promotes the use of models. There is always a model whether we are aware of it or not, but the model we choose determines what we find.

Science places a high value on precision, but what about things we cannot be precise about, where apparent opposites come together? Science passes over entities that cannot be measured; it takes things out of context and decontextualizes the problem. We put our faith in science because it is seen to be objective, but science is not value free. A lot of scientific research is not adequately designed; we know that the Hawthorne effect can influence scientific results and positive findings are more likely to be published than negative ones. We can’t ask science to do what it can’t do. A hypothesis cannot be proved nor disproved. Each comes with many assumptions. Proof used to mean a trial run (as in a printed proof).

Science cannot provide us with dependable ultimate truths. It’s not pointless, but it does not provide us with reliable truth. Philosophy equally has problems with notions of intuition, uncertainty, rationality, reason and the complexity of truth.

Iain quoted Edmund Burke as saying – ‘It is the nature of all greatness not to be exact’, and Rabindranath Tagore:

Truth is not a proposition but a disposition towards the world. It is related to trust and what one believes. Belief is not signing up to a proposition but about a relationship. Truth and belief used to be embodied. We can’t passively wait for them. We have to make a move to meet them. There is no fail-safe path to truth.

Iain believes that truth has intrinsic value not just instrumental value. He mentioned but disagreed with Pascal’s wager. Pascal proposed that whether or not there is a God, we should live our lives as though there is one – just to be on the safe side! Iain believes truth is a moral value, like beauty and goodness. It is not a human convention. There will be truth when we are no longer around to see it. The pursuit of truth is greater than the possession of truth. Potential is greater than actuality.

Personal Reflection

I don’t remember God being mentioned on last year’s course as much as on this year’s course and it was interesting to hear Iain describe briefly what ‘God’ means to him. There was virtually no explicit reference to religion during the course. It seemed to me that the word ‘God’ was being used to identify or name ideas for which there is no adequate universally agreed explanation.

Reflecting on this session I remember that I have, in the past, done my fair share of searching for answers to the question of what is life all about and thinking that there must be more to it than all this. I was a child of the 60s (actually I wasn’t a child, I was already in my twenties), so I followed the Maharishi Mahesh Yogi, owned a copy of the I Ching and practised meditation, before becoming dissatisfied and moving on to ‘religion’ (Christianity), with which, after a few year, I became equally dissatisfied.

I also remember that in the 90s when doing an MA in Education I read and wrote about the meaning of truth in relation to an assignment on research methods. On digging out this assignment, I find it includes these quotes:

‘No finitely describable system, or finite language, can prove all truths. Truth cannot fully be caught in a finite net’ (Nagel & Newman quoting Godel’s Theorem, 1959).

‘… there can be many points of view, or many faces of truth, some even mutually contradictory, and yet all equally real in the potential sense …’ (Zohar & Marshall, 1994).

So on reflection I can see that questions about truth have accompanied my life since my twenties and maybe even before, which perhaps explains my interest in Iain McGilchrist’s work and why it resonates. Having said that, what I like about Iain’s work is that whilst it makes reference to spirituality, it is more about how the right and left hemispheres view the world than about ‘God’ or religion. As he writes in The Master and his Emissary (p.92)

‘There is not likely to be ‘a God spot’ in the brain, and the area is fraught with problems of terminology and methodology: but there are areas that are often implicated as accompaniments of religious experience.‘

It’s not religion, but the idea of being able to see the ‘big picture’ and what it means to have an open mind that intrigues me.
