NATURE AND SUPERNATURE
Throughout the long tradition of European thought it has been said, not by everyone but by most people, or at any rate by most of those who have proved that they have a right to be heard, that Nature, though it is a thing that really exists, is not a thing that exists in itself or in its own right, but a thing which depends for its existence upon something else.
R. G. COLLINGWOOD,
The Idea of Nature, III iii.
If our argument has been sound, acts of reasoning are not interlocked with the total interlocking system of Nature as all its other items are interlocked with one another. They are connected with it in a different way; as the understanding of a machine is certainly connected with the machine but not in the way the parts of the machine are connected with each other. The knowledge of a thing is not one of the thing’s parts. In this sense something beyond Nature operates whenever we reason. I am not maintaining that consciousness as a whole must necessarily be put in the same position. Pleasures, pains, fears, hopes, affections and mental images need not. No absurdity would follow from regarding them as parts of Nature. The distinction we have to make is not one between ‘mind’ and ‘matter’, much less between ‘soul’ and ‘body’ (hard words, all four of them) but between Reason and Nature: the frontier coming not where the ‘outer world’ ends and what I should ordinarily call ‘myself’ begins, but between reason and the whole mass of non-rational events whether physical or psychological.
At that frontier we find a great deal of traffic but it is all one-way traffic. It is a matter of daily experience that rational thoughts induce and enable us to alter the course of Nature—of physical nature when we use mathematics to build bridges, or of psychological nature when we apply arguments to alter our own emotions. We succeed in modifying physical nature more often and more completely than we succeed in modifying psychological nature, but we do at least a little to both. On the other hand, Nature is quite powerless to produce rational thought: not that she never modifies our thinking but that the moment she does so, it ceases (for that very reason) to be rational. For, as we have seen, a train of thought loses all rational credentials as soon as it can be shown to be wholly the result of non-rational causes. When Nature,
