The Poetics of Thought

Space

Posted in Uncategorized by Fred McVittie on September 22, 2009

In their book ‘The View from the Centre of the Universe’ Joel Primack and Nancy Abrams say this:

In their hearts, most people are still living in an imagined universe, where space is simply emptiness, stars are scattered randomly, and common sense is a reliable guide. In this imagined universe, we humans have no special place and often feel insignificant. (2006: 3)

What I want to begin here is a thought that parts company with Primack and Adams and their version of this heartfelt common sense.  I want to suggest that common sense tells us that space is anything but simple and that humans do indeed have a special place.  I want to begin though with the big picture of space before bringing it up close and personal.

Thomas Kuhn’s notion of the ‘paradigm shift’, articulated in ‘The Structure of Scientific Revolutions’ (1968), postulated that occasionally there are major changes in the way that science understands (all or part of) the world. The most commonly-cited example of such a shift concerns space and how it is conceptualized.  This is the Copernican revolution from an Earth-centered universe to one centered on the Sun; a revolution in which the old order of theories, models, diagrams, and mechanisms is dismissed in favour of the new. In Kuhn, it is a necessary consequence of this revolutionary overturning that what went before it becomes wrong and that apostles of the new, (after moving through a brief period of being heretics) become keepers of the new flame and upholders of the new truth. Old is wrong, new is right.

According to Primack and Adams (ibid) a more accurate understanding of what happens during these times is not a replacement of one truth by another but rather the re-interpretation of the data of the world such that it applies to a wider set of circumstances and covers a larger set of phenomena.  They give the example of Newtonian physics giving way to the relativity of Einstein, an apparent paradigm shift in which new knowledge describes the universe in ways which are more complete than the old.  What they point out however is that Newtonian physics is not rendered wrong by the development of this new science, it is simply redefined as a description of parts of the universe only; basically the middle-sized and slow moving parts; and as long as its methods are applied only to those parts it is as accurate, and more efficient, that any other model or method.  It was, after all, Newtonian physics which put men on the moon.

This understanding of certain descriptions of the world having different applicability than others also applies to our understandings of space; the Ptolomaic picture of the Earth-centered universe is not ‘wrong’ in any transcendental sense,  it is instead a local interpretation of the data concerning planetary movement. In many cases it is preferable to work with the assumption that the Earth is stationary and central rather orbital and peripheral. When we make appointments or set our watches we do not consider this as stating the location of the Earth in its orbit around the Sun, or the number of degrees through which it has rotated. We refer to sunrise not Earthfall and we watch the Sun go down over the ocean, not the Earth turning its face away into the darkening night. For most purposes the Ptolomaic model of the universe in which Earth is the centre of attention is sufficient. This is not to say that when we use such Earth-centered concepts we are using a kind of lazy shorthand, or are being inaccurate. When the application of the Ptolomaic paradigm is limited to specific uses such as these it is as accurate, and more efficient, that the Copernican.

On the even more local scale of embodied experience, we can extend this notion of overlapping or simultaneous paradigms to include the apparently self-evident wrong-headedness of Flat Earth theory. The Earth when seen from space is obviously a ball and any depiction of the Earth as a two-dimensional surface is demonstrably inaccurate. However, in day to day life we routinely work with the assumption that it is indeed a flat plane, and are rarely proved wrong. When we measure a room prior to fitting a carpet, or stake out the foundations of a building, we do not take the spherical nature of the Earth into account. It would be perfectly possible to include this curvature in our calculations but since this difference would be insignificant (smaller by far than the variations in the landscape itself) it would be foolish to do so. It is at this level that embodied experience and the paradigms which make up that experience, become available as accurate, relevant theory.

There are, therefore, good pragmatic reasons why we might assume that the Earth is flat and why we might live large parts of our lives in the shadow of that assumption.  Furthermore, there would be very little reason at all why we should develop an intuition which suggests otherwise.  From the perspective of our evolutionary history there would be no benefit to be gained from this kind of abstract spherical knowing, in stark contrast with the distinct advantages claimed by those of our ancestors who cared less about such abstractions and more about the tiger hiding in the bushes at the other side of the, apparently flat, clearing in this forest.  Given the tiny slice of human history during which knowledge of the curvature of the Earth would be advantageous, basically since the advent of extended seafaring, it is wildly unlikely that we would have a naturally intuitive grasp of this reality.  Our phylogeny, as well as our phenomenology, constantly proposes and confirms our position as Flat-Earthers.

If this seems ludicrous then it is worth noting in passing that the Copernican model tends to promote an understanding of the universe which is as partial in its own way as the Ptolomaic which preceded it. A casual interpretation of the Sun-centered model seems to indicate a stationary star orbited by moving planets, but of course, in relativity, nothing is stationary in absolute terms and by most accounts the Sun itself is hurtling at several thousand miles an hour in the direction of Andromeda, with the planets flailing around it like the loose reins of a runaway horse. Copernicus put his thumb on the Sun and momentarily arrested its wild flight and, in doing so, revealed a pattern in the relationship of the movement of the planets, but the Copernican map is not of the territory of the real solar system, any more than a 2-dimensional map of the Earth is an accurate rendition of the real globe. It is more a graph or schematic showing the pattern of relations he discovered.

What I want to suggest here is that, whilst we are able to fully grasp the idea of the Earth as a ball spinning in the empty space that Primack and Abrams attributed to common sense, in fact this sense is anything but common.  In point of phenomenal fact our senses tell us, and told thousands of generations of our ancestors, that we are standing on a plane, beneath a dome of sky, looking out to a horizon that encircles us.

This is one of the experiential logics of embodied space that I believe structure our cognition and that I want to explore.  This organised perception of space, in which the organising principle is the human sensorimotor system, contributes to the repertoire of structures which allow meaning and thought to emerge.

All space, from the most counter-intuitive of Einstein and Hilbert to the most transparently familiar of Newton and Descartes is rendered sensible through the confabulatory cognitive operations I have talked about earlier.  Yet it is this embodied phenomenal space which perhaps we are most comfortable describing in terms of a ‘poetics’, as indeed Gaston Bachelard did in his most famous book ‘The Poetics of Space’ (1994).  The philosopher Michel Foucault had this to say about Bachelard’s work, which resonates strongly with the sense I am groping for here:

“Bachelard’s monumental work and the descriptions of phenomenologists have taught us that we do not live in a homogeneous and empty space, but on the contrary in a space thoroughly imbued with quantities and perhaps thoroughly fantasmatic as well.  The space of our primary perception, the space of our dreams and that of our passions hold within themselves qualities that seem intrinsic: these is a light, ethereal, transparent space, or again a dark, rough, encumbered space; a space from above, of summits, or on the contrary a space from below, of mud; or again a space that can be flowing like sparkling water, or a space that is fixed, congealed, like stone or crystal.” (1986:23).

Embodied phenomenal space has a poetic logic of its own; the local interpretation of universal laws that our bodies obey and perform.  This space, I would argue, is the one which most readily provides the capacity in which meaning and thought might emerge.
