articulate what the new science could do, but as a devout Catholic he also wanted to preserve the gift of Christian salvation. His answer was to postulate two distinct ‘realms’ of experience: the res extensa or extended realm of matter in motion, and the res cogitans, the ‘realm’ of thoughts, feelings, morality and spiritual consequence. The new science would tell us about the former, but for Descartes science would have nothing to say about the latter. In effect, Descartes tried to preserve the dualism inherent in medieval thinking while also opening up the possibilities he so boldly saw in the emerging science. As a Catholic, he understood that the Christian soul could not be bound by mathematical laws, and since he believed that mathematics was the language of the material world there had to be some ‘realm’ apart from those laws.
Descartes failed in the same sense that Newton failed; his theological trappings were stripped away by later generations who took what he had done and used it to promulgate a purely secular cosmology. Since the Enlightenment we have come to use the word ‘cosmos’ to mean the purely physical world and ‘cosmology’ to mean our concept of the material domain alone. We have forgotten the wider picture in which ‘the cosmos’ encompassed multiple levels of being; we tell ourselves that older cosmologies are childish tales and that we moderns supposedly have outgrown these stories and faced reality ‘squarely’ to work out where we ‘truly’ are.
SPACE AND SELF
In discussions about science and religion it is often noted how corrosive a mechanistic philosophy was to the Christian idea of a soul; what is not widely understood is how important a role our conception of space has played in this story. Eighteenth-century natural philosophy was premised on a neutral, homogeneous, infinite and passive space. The very qualities of Euclid’s ideal that made it such a fruitful foundation for the development of physical science are just the qualities that have become so problematic for those who wish to assert the reality of a ‘spiritual’ plane of being. For medieval Christians, a dualistic conception of the human person went hand in hand with a dualistic spatial scheme; with the advent of a purely physicalist world picture it has become increasingly difficult to argue for the reality of any kind of non-physical dimension to human existence.
Christians are not the only ones who might be troubled by this development. Secularists can be concerned too, for the equation of physical space with the totality of ‘reality’ also problematises the idea of a human self. What does it mean to say that the self exists if we cannot locate it on a map? In talks I give about this subject I am sometimes asked during question time to ‘prove that the self exists’. It is always a young man who makes this demand and he is usually a student of physics or philosophy. He is well read and he means his question in earnest. He does not believe that the self exists and he wants me to prove it does. At first I was puzzled by this demand, then I realised how I should answer: If the self does not exist, I say, then his self doesn’t, so I shall move right along to a question from someone who does. I assume there are some selves in the room who do exist.
But are there? In the mathematically defined space of modern cosmology do any of us exist?
A SCIENCE OF MIND
In the early eighteenth century, the philosopher John Locke claimed that it wasn’t stable for a society to have only a science of body. According to Locke, we would eventually need to develop a complementary science of mind, which is what Freud attempted in the late nineteenth century. The psychoanalytic tradition of the past century may be read, in part, as one

reaction to the cosmological shift that took place two hundred years earlier. Freudian psychoanalytics and its many descendants are attempts to make sense of the self in a non-spatial framework and in a very real way to get beyond the metaphysical dualism of our Christian and Greek heritage. Personally I find myself greatly in sympathy with the whole exercise and although I think its therapeutic effects are easily overstated, I do believe the psychoanalytic stream of theory and practice is a powerful response to what remains within our society a cosmologically inspired trauma.
I do not mean to propose here that every individual is personally feeling this rent; but it is clear that a great many of us are. For all of the immense practical and epistemic triumphs of modern scientific metaphysics, which is premised on a homogeneous continuous conception of space, it is manifestly not being accepted by huge slabs of our population. Reactions against it have been vast and varied from Blake’s and Keat’s scathing poetic critiques (that science would ‘conquer by rule and line’, ‘unweave the rainbow’ and so on), to Alfred Whitehead’s enigmatically difficult ‘process philosophy’, which attempts to articulate a reality in which neither matter nor mind take precedence, rather both are artefacts of a fundamentally procedural world. Intellectual alternatives to pure physicalism are myriad: Teilhard de Chardin, Loren Eiseley, Mircea Eliade and Rupert Sheldrake may all be read as responses, to say nothing of the exponentially expanding volume of New Age literature. To the continuing horror of many champions of science, belief in astral planes, psychic channelling, reincarnation and past lives seems to be growing stronger.
In part I believe what this represents is a widespread social refusal of spatial monism. Whole sectors of our society are just not buying it! More than twenty million people bought The Celestine Prophecy (it is one of the most successful books of all time), which posits that when we become the beings we ought to be our souls ‘cross over’ (via some processes of quantum mechanics) to a higher spatial plane. In the age of science, one of the most pervasive fantasies is indeed the existence of other spaces of being: from the X-Files and Buffy the Vampire Slayer to Lost and Battlestar Galactica, our television screens offer a steady diet of realities in which multiple spaces and planes of being co-exist. (Cyberfiction offers yet another response – the fantasy of downloading one’s mind into a computer to live for ever in a virtual world is nothing more, though a good deal less, than a technological version of Heaven.) One of the great philosophical projects of the post-Enlightenment era has been to articulate non-spatialised conceptions of the self in relation to the cosmos; yet judging by the evidence of the most pervasive medium on our planet the enterprise has met with little success in a sociological sense. Even science fiction writers – Carl Sagan, no less – keep on inventing wormholes through the physio-spatial matrix to other, suspiciously spiritualised, places of being.
Those of us who love science may choose to interpret all this as a kind of play, and in some sense it is, but the refusal to accept spatial monism is also in part fuelling the rise of Creationism and other fundamentalist brands of Christianity. At the same time that spatial monism erased the division between earthly and heavenly space, it also provided a platform for erasing any fundamental distinction between living and non-living things. In the new era of science, continuity itself became the epistemic model – the continuity of the laws of nature, the continuity of space, the continuity of matter, the continuity of life. No body is special, because no thing is special, because no place is special. Humans are related to apes because, in the end, we are all just inert matter floating in a homogeneous void. The fundamentalist rebellion against Darwinism is not just a rejection of the continuity proposed by biology but in a wider, and less obvious way a rejection of the very premise of totalised cosmic continuity. Christians who insist on a space for the soul wish to reclaim that part of the medieval world picture that literally gave a place to moral human agents. Though I do not endorse their specific responses, I believe that in this respect the religious right point us to a deep and abiding sociological problem that will not be easily resolved and which ought not be so readily dismissed.
CONCLUSION
At all times in The Divine Comedy Dante knew where he was. He was embedded in a cosmos that gave him a position physically, spiritually and psychologically. One of the many strengths of the Comedy is that it gives a concrete landscape to both soul and psyche. While the book must be read as the journey of a Christian soul through Hell and Purgation towards Paradise, it
