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 →
The age of increasing importance of science is usually claimed to have begun with Copernicus in the early 16th Century when he argued that the sun is the centre of the solar system and not the earth as the church had always insisted. (This is stated in the Psalms of the Old Testament and by the Greek astronomer Ptolemy in the 2nd Century.) In fact, so afraid was Copernicus of incurring the wrath of the clergy that publication of his beliefs did not take place until after his death. Even Galileo, later confirming the facts by telescope, was forced to deny it since he wished to stay alive. Galileo advocated that all prior beliefs and opinion should be kept out of scientific observation, which should be completely objective. Needless to say, once such ideas gained support, the authority of the church began to diminish and their dogmatic pronouncements about the nature of everything began to be supplanted by more tentative suggestions based upon specific observation and experiment.
Isaac Newton was born in the same year that Galileo died and his discoveries were to have a devastating effect on religious faith. Once it became accepted that the workings of the universe could be understood through scientific laws, the idea of a divine creation became suspect. Man was just a tiny phenomenon in a vast universe, no longer the centre of everything. This had a profound effect upon man’s self-image and outlook. Previously it had been believed that our earth was effectively the creation and that man was the most important being in it, capable of communing with God and aspiring to union with Him. Henceforth it became increasingly apparent that the earth was insignificant in the immensity of the universe and the concomitant conclusion was that man himself was nowhere near so important as had previously been supposed.
