In his magnum opus, The Matter with Things, Iain McGilchrist identifies Henri Bergson as a major contibutor to the understanding of the way we human beings know about the world.
Essentially, there are two modes of knowing, which I will characterise in a word as intuition and rationality. Intuition is to do with direct perception of the world and understanding what is needed; rationality is to do with language and analysis, rationalising about the world. Intuition ‘presences’ in the world; rationality ‘re-presents’ the world in its own terms.
These two modes were well understood by many thinkers of the past. In the early 1900s these included Bergson, William James, Einstein (see featured quote) and other quantum pioneers. In earlier times, for example, the Romantic movement of such as Wordsworth and Coleridge strove to emphasise the continued importance of direct perception in an encroaching world of rationality. The two modes are also well understood in the world of astrology, where the planet Jupiter represents the faculty of direct perception/ intuition, whereas Mercury represents rational/ analytical intelligence.
What neurologist/psychologist/philosopher Iain McGilchrist adds to this picture is the correlation of the intuitive intelligence with the right brain, and of rationality with the left brain – emerging from modern studies in neurology.
Humans evolved with these two different capabilities because they were necessary for survival. For instance, a hunt might have involved analytical planning to get in the right place to hunt, but intuitive perceptions of the dangers posed by other wild animals in the area. We rely on the combination of these two intelligences.
However, contrary to what you might think, there is no symmetry between the two in terms of their function. Intuition grounds us in the real world; rationality theorises about it. Our intelligence is powerful because the two co-operate – intuition suggests an approach; rationality evaluates and proposes the way to go; then intuition confirms – intuition is the Master.
The disturbing thing about left brain rationality, spotted by Bergson and others, is that it does not necessarily see the need for grounded intuition at all. In this extreme case it usurps the role of the right hemisphere, the intuition and the connection with the real world. The map becomes the territory. A world of abstraction is confused for reality itself. This was the theme of McGilchrist’s previous book The Master and His Emissary – the left brain messenger taking over and ignoring the right brain connection with reality.
Looking at today’s world, it is difficult to avoid the conclusion that this is essentially what has happened to humanity in the large. Our connection with reality, with planet earth, is being slowly destroyed by the left-brain machinations of politics, capitalism, business, technology, consumerism. It will all end in tears for many people and many species of life; indeed it already has.
Yet we still each have those intuitive right brains and there will always be those who know the way to go, who love nature, the earth, their fellow beings, who fight the good fight against left brain extremism. This is the dance of life, and the peculiar destiny of human beings…
