Miracles - C. S. Lewis [3]
Everyone will have seen that the One Self-existent Thing–or the small class of self-existent things–in which Supernaturalists believe, is what we call God or the gods. I propose for the rest of this book to treat only that form of Supernaturalism which believes in one God; partly because polytheism is not likely to be a live issue for most of my readers, and partly because those who believed in many gods very seldom, in fact, regarded their gods as creators of the universe and as self-existent. The gods of Greece were not really supernatural in the strict sense which I am giving to the word. They were products of the total system of things and included within it. This introduces an important distinction.
The difference between Naturalism and Supernaturalism is not exactly the same as the difference between belief in a God and disbelief. Naturalism, without ceasing to be itself, could admit a certain kind of God. The great interlocking event called Nature might be such as to produce at some stage a great cosmic consciousness, an indwelling ‘God’ arising from the whole process as human mind arises (according to the Naturalists) from human organisms. A Naturalist would not object to that sort of God. The reason is this. Such a God would not stand outside Nature or the total system, would not be existing ‘on his own’. It would still be ‘the whole show’ which was the basic Fact, and such a God would merely be one of the things (even if he were the most interesting) which the basic Fact contained. What Naturalism cannot accept is the idea of a God who stands outside Nature and made it.
We are now in a position to state the difference between the Naturalist and the Supernaturalist despite the fact that they do not mean the same by the word Nature. The Naturalist believes that a great process, of ‘becoming’, exists ‘on its own’ in space and time, and that nothing else exists—we call particular things and events being only the parts into which we analyse the great process or the shapes which that process takes at given moments and given points in space. This single, total reality he calls Nature. The Supernaturalist believes that one Thing exists on its own and has produced the framework of space and time and the procession of systematically connected events which fill them. This framework, and this filling, he calls Nature. It may, or may not, be the only reality which the one Primary Thing has produced. There might be other systems in addition to the one we call Nature.
In that sense there might be several ‘Natures’. This conception must be kept quite distinct from what is commonly called ‘plurality of worlds’—i.e. different solar systems or different galaxies, ‘island universes’ existing in widely separated parts of a single space and time. These, however remote, would be parts of the same Nature as our own sun: it and they would be interlocked by being in relations to one another, spatial and temporal relations and casual relations as well. And it is just this reciprocal interlocking within a system which makes it what we call a Nature. Other Natures might not be spatio-temporal at all: or, if any of them were, their space and time would have no spatial or temporal relation to ours. It is just this discontinuity, this failure of interlocking, which would justify us in calling them different Natures. This does not mean that there would be absolutely no relation between them; they would be related by their common derivation
