The Mind-Body Problem
Descartes’ separation of man into the two aspects of mind and matter also became the principal way in which Westerners subsequently viewed the world. Matter is extended in space, can be divided and so on, while mind is indivisible and seems to exist separate from the body, somehow outside of space. This is the theory known as Cartesian Dualism. Unfortunately, he was never able to explain how such completely different ‘substances’ were able to interact. The idea of an immaterial ‘little me’ somehow sitting in the brain (Descartes thought the soul resided in the pineal gland) and interpreting the information transmitted from the eyes and other material senses just did not make sense. How could this interface work? The so-called ‘mind-body problem’ has intrigued philosophers ever since and no universally accepted model of the nature of the self has yet emerged.
One of his disciples, a Dutchman called Arnold Geulincx, suggested that the mind and body were separately governed by God, who kept the two in synchronisation, like clocks. Thus, when we decide to do something and it happens, such as getting out of bed, there is no actual interaction between the two, no ‘willing’ as such, it is simply the consequence of the two being synchronised. A similar theory, called Occasionalism, was proposed by the French priest, Nicolas Malebranche. He said that neither mental nor physical events cause other events. Instead, what we call a cause is simply the occasion for God to exercise his will and instigate what we call the effect; there is no actual connection between the two events at all. All of this meant that life is strictly deterministic, with no place for free will and everything happening according to physical (or divine) law. Continue reading
