The Middle Path - A Neurological Perspective
I wish to continue with the theme of the middle path, this balance point between the polarities of life. I mentioned in the last blog that I believe the problem is ideation, where we give too much authority to ideas and philosophies rather than trusting in our natural knowing. I'd like to clarify that this doesn't mean that ideas are wrong, or that the 'rational' mind should be denied in favour of feelings and instincts. These faculties are all natural parts of our human being, designed to work together in harmony and balance. The problem only arises when we favour one or the other too heavily, and impair their natural communication with each other. Supportive evidence for this need for a balanced approach is now coming from the field of science, which for so long has pushed us too far to the mental side of life. It's emerging out of the very exciting field of biological psychology.
Advances in electro imaging technology, such as MRI and PET scans, are allowing investigators to form a remarkably detailed picture of which aspects of our brains are doing what. This has been going on for a while, in fact if you haven't heard something about the differences between our left and right brain you've probably been hiding out in a mountain cave for the last twenty years. Popular myth has it that the right side of our brain is the feminine, responsible for creativity, emotion, music, relationship, intuition and so forth. The left is the masculine, responsible for language, linear logic, goal seeking, planning and so forth.
These are gross over simplifications of the available evidence, but there is enough truth to them to make it a useful model for discussion. Investigators have found a way to temporarily 'lesion', or shut down particular areas of the brain, allowing them to determine what alters during these episodes of dysfunction. For instance, when certain areas of the left hemisphere are lesioned, the person experiences impairment in their capacity for speech, reasoning, definition, the passing of time and focussed thoughts. When particular areas of the right hemisphere are lesioned some people lose their ability to distinguish emotion, perceive patterns in information, recall events, and recognise faces.
Let me stress that these differences are not nearly as predictable or as defined as many popular books on the subject would assert, but they give rise to interesting questions. What we do know is the the separate hemispheres of the brain control the opposite side of the body, and that the right brain has long been considered the seat of creativity, free will, emotion and motivation - considered the feminine mind. In fact the Catholic church has been waging war against the right brain for centuries. The word sinister, which is latin for 'left' (sinistra) came to mean evil in church doctrine. Left handedness was considered the mark of the devil and children with a left handed dominance were still being ruthlessly suppressed and 'retrained' as late as the 1960's.
Brain imaging studies have shown us that states of deep meditation and prayer generate increased activity in the right cortex, indicating that this area of our brain is involved in our personal connection to spirituality. However, belief based thinking, such as that involved in religious theology and ritual, mainly involve the left cortex. What we also know is that people who have suffered serious trauma often have a tendency to favour left brain thinking, which some put down to a tendency to avoid emotionally linked memories which seem to involve the right brain.
It appears that these two polarities need to work together to produce the best results. Most genius level intellects and high achievers in fields of innovation are famous for being people who are active in using both parts of their brain. Einstein was a great example of this. He related that once he had assimilated all the available information on the subject, he would determine his objective (both left brain activities) and then give it to his unconscious to figure out. He would then get on with other things until it came back at him with a response, which usually took the form of symbolic images (right brain activity). But this doesn't just work for geniuses. Every day life is a balancing act between our analytic mind and our intuitive reasoning - between our emotional responses and our cognitive abilities.
We all know people who favour one aspect over the other, usually to their detriment. For instance, those who stray too far to the left and live their lives in a highly intellectual and emotionally disengaged manner are usually dreadful at relationship, inclined to overwork, pay too little attention to their health and often lead quite bland unsatisfying lives. On the other hand (so to speak), some people go too far the other way and live lives of intense emotional drama while being unable to plan, set goals, discipline themselves or reason very well. Progress towards happiness for these people usually only comes when they recognise the need to embrace the 'other side' of life and develop their neglected faculties.
It's actually quite natural that different people specialise and tend more one way than the other, it's part of the diversity of human existence that go's to make a whole and interesting society, so long as we don't take it so far that we lose personal balance. Fortunately we all have both capacities, the ability to engage both sides of our brain in concert and balance. No matter where we are, or which way we tend, its never too late too redress the balance. Perhaps we need to take an art class, or a course in critical thinking, learn to play an instrument or develop self discipline. Whatever the need, just recognising that we may be out of balance is the first step back towards the middle.
Grace be with you.
