Science and Consensus

Joi Ito posted a very interesting review of a book entitled Science in Action by Bruno Latour. The focus of the book (or at least of Joi's take on it) is that scientific "facts" are really a form of what some people have called consensus reality. (I point to the wikipedia definition for convenience, but I think that the term may have been coined by psychologist Charles Tart.) That is, facts are not really facts at all, but rather postulates that have become generally accepted through a process of social consensus-building. Many is the "fact" that never achieves that status because no one pays attention to the postulate or observation in question and so no consensus is built.
Of course, this is a very anthropocentric view. It reminds me a bit of the time Samuel Johnson was asked to comment on Bishop Berkeley's theory that everything exists only in the mind. Johnson said, "I refute it thus:", kicking a stone to complete the sentence. I like to think that both the external world and the human mind play a conjoined role in defining "reality". In short, I believe A) there is an objective world outside of us, B) that we perceive it, C) that we tell ourselves stories about it (i.e. build language abstractions and other mental models that describe it), and finally D) close the loop by mapping the world into our models and affirming that mapping as "reality". A "fact", in the sense that Joi and Bruno Latour are talking about it, is the completion of all four stages of this perceptual process.
But still, Joi's point is a good one. In practice, A, B, C, and D often get out of sync. As Joi notes, "facts" become "black boxes" that are very hard to take apart again. We have theories (C) that have reified into "facts" (D) and are hard to dislodge, even in the face of new data (B) suggesting that things (A) aren't what they seem. And this isn't just in the scientific realm, but in the interpersonal one. How many people do you know who don't have preconceived notions that keep them from seeing a situation or another person accurately? Why should our interpretation of the physical world be any less moderated by our existing beliefs?
I remember a history of science class I took in college. Like every other such class, we read Thomas Kuhn's classic The Structure of Scientific Revolutions, which introduced the term "paradigm shift" to describe the changeover from Ptolemaic to Copernican astronomy. But my professor, Owen Gingerich, had a twist on Kuhn's idea. Ptolemy's system didn't break down just because new observations prompted a theory that better fit the data, but because of an entire social and intellectual milieu that was ready to accept such a change. It was an aesthetic and philosophical revolution as much as it was a scientific one.
And that takes me to one of my all time favorite authors, poet Wallace Stevens. Stevens' theme, repeated throughout his poems, is the dialogue between the world and the mind:
And out of what one sees and hears and out
Of what one feels, who could have thought to make
So many selves, so many sensuous worlds,
As if the air, the mid-day air, was swarming
With the metaphysical changes that occur,
Merely in living as and where we live.
In college, a friend of mine named Lewis Gannet (whom I've long lost touch with) wrote an amazing paper drawing ideas from Claude Levi-Strauss's book The Savage Mind and Wallace Stevens' sole book of essays, The Necessary Angel, to argue that while earlier societies had shared belief systems, our challenge today is to build shared beliefs knowing that they are not "true". Stevens' solution, in "Notes Toward a Supreme Fiction", was to recognize that the construction of reality is an artistic act, not just a scientific one.
At about the same time, I studied with a man named George Simon, who was trying to build what he called "languages for consciousness," believing, like Benjamin Whorf (author of Language, Thought and Reality), that our language limits our ability to perceive, and that until we have languages for certain states of consciousness and perception, we won't be able to use them. He saw his work as an extension of general semantics, a system developed in the 30's by Alfred Korzybski, author of Science and Sanity. Korzybski's famous statement, "the map is not the territory" is more than an observation; it's a tool for living more perceptively. A lot of my friend George's work was in training people to open up the ladder of perception, to recognize the difference between what you are experiencing directly vs. through various levels of abstraction, to let go preconceived notions and let the world come in fresh.
George also argued that as human consciousness evolves, certain things that were once on the frontiers of awareness, and that were experienced with near-mystical force, become commonplaces as they are routinely abstracted into language.
In my classics honors thesis at Harvard, I used this premise to assess certain of Plato's dialogues, arguing that the mystical overtones with which Socrates describes concepts like justice and truth were the result of the newness of his ideas. As we "rehearse" these now familiar ideas thousands of years later, we don't get that same rush. Most of us receive them at a level of abstraction, fitting them into our accepted system of facts, rather than taking them in through the entire ABCD perceptual cycle. (And yes, I recently came across a copy of the thesis, and when I find time, I'll scan it and put it up online.)
Wow, I had no idea that Joi's blog would set me off on such a tour of the underpinnings of my personal intellectual history! But I have to say that I still find this kind of thinking incredibly stimulating, and my early training a big help in coming at ideas and situations with a fresh and balanced eye.
P.S.
My friend George died in an accident in 1973, and his writings were never widely published.
Korzybski's book is out of print, but there's a contemporary book on general semantics called Drive Yourself Sane that seems to be fairly highly recommended, and of course, there's A.E. van Vogt's science-fiction classic, The World of Null-A, which is about to be reissued.
Some related ideas can be found in a book called Focusing by Eugene Gendlin. Gendlin's work comes from a completely different tradition than general semantics, but it has some similarities to parts of George Simon's work in training people to surrender to their perceptions and let new information come in, rather than hanging on so hard to existing maps.

It got me to reflecting that, generally speaking, we don't "see" air or radio, and fish can't "see" water or x-rays, yet, in both cases these realities surround AND pervade us. Which is simply to use these observations as a motivation in noticing that 'Out there/In here', 'Objective/Subjective', and other visible and invisible dichotomies that most of present day modern classical science is built upon, and much of how we, on a moment-to-moment basis, have come to and continue to practice our daily being and perceiving, are such as a result of how we enact ourselves, consciously and unconsciously.
[I make the distinction between "classical" and "other" enquiries because enquiries like Complexity (a la the Santa Fe Institute) and Quantum Mechanics on the one hand, and Meditation and the exploration of 'Inner States' on the other, are mapping [mapping as a process and as a product] realms where Science's foundational dichotomisations cannot be practised and yet made consistent nor fundamentally resonant (correspondence with) with our widening experiences, descriptions or enactments of the world (universe)).
The nature of this enactment is all around and within us, in our dynamic personal, social and professional cultures. Thomas Kuhn spoke eloquently of "disciplinary matrices" in science, using the concept of an 'eidos', in his writings, an eidos being a system of methods. An eidos, in Kuhn's words, is a disciplinary matrix which defines and describes what a given society takes as its metaphysical assumptions, sensible formulations, meaningful challenges and sanctioned methods in its principal endeavours.
Where it exists a disciplinary matrix is the cognitive part of any organisational structure. It is made up of the criteria of credibility, the logic used in thinking and acting, and the basic ideas by which members of an organisation organise, interpret and share experience. It defines what the organisation takes as its models [the beliefs and assumptions], symbolic generalisations [the sensible formulations], values [as expressed in the meaningful challenges], and exemplars [the sanctioned methods] in its principal endeavours.
Historically Kuhn was talking about science, and in some of his discussions, how alike its practise is to the practise of religion. A little reflection on our parts allows us to also observe that his view is not inconsistent in talking about any population of systems which share similar cognitive facilities, experiential content and common injunctions - whether that population is a pride of lions, a TCP/IP-based storage network, a drug cartel, or a group of wall street arbitrageurs.
It's often said that culture democratizes perception (hence the consensus), sometimes lulling us into thinking that this mainly means that it provides a process and means for individuals to become part of a collective (who enact and practice the culture). Yet more violently and necessarily, culture enforces perception (THE consensus), providing many "curative" forces to ensure that "you 'see' what we 'see' and 'do' what we 'do'" with such feedback as: or else, no tenure, you're insane, you're disconnected, if you do that again or see that again I'll spank you, etc. From the moment of conception and even before, our variegated human "culture" is being injected, projected, enacted and practiced for us, with us and by us until we "get it right" (or are rejected or killed). Fortunately, as in any population, there are the necessary-for-the-population's-existence dynamics of chance, mutation, evolution, resistance, 'cranks', 'idiots', 'genius' and more, and sometimes being one and the same within a single individual (smile).
Current 'science' it seems to me is that set of disciplinary matrices (being the sum total of "How we do things around here with respect to discovering, determining and blessing knowledge {and those who do these things}") that are presently built on and takes as "real" a fundamental and, historically, Aristotelian dichotomy of "in here ain't out there" and vice-versa. Indeed, modern science, except perhaps in Quantum Physics, since about 1932 [Von Neumann, Dirac, Heisenberg, Schrodinger, Feynmann et al], doesn't presently generally allow for "suppose it isn't either, neither, all or both".
"Is it a wave or is it a particle?" was first a paradox before it became "it's a field" (the first of several efforts in regarding waves and particles as symptomatic of some'thing' or some'think' else'where'). The place your blog pointed me towards is this: Just as 'is it a wave or is it a particle' is no longer regarded as a fundamental dichotomy that is "true" about the world (except perhaps as a correspondence with our methods and chosen contexts of investigation), might that not suggest that 'The map is not the territory', or, differently expressed, 'Is it the map or is it the territory' might also be distinctions (and hence processes and products) that are also symptomatic of a particular set of choices of some'thing', some'think' or some ways of acting we practise, and therefore as some suggest of the nature (not effects) of those results as "illusory", not in the sense of hallucination, but in the deeper sense of not being fundamental and in the sense that the realm a phenomena is real in and our participative ability to enact ourselves in that realm determine our "reality", and not the other way around. Or as Q'ai Gon,a Jedi master in the Star Wars movie 'Revenge of the Clones' remarks: "Your focus determines your reality". And for some five hundred years 'Science' has been looking with near enough a single focus.
Much of the ground for our Science beliefs and practices, cultural, disciplinary and otherwise, is bound over by our use of and the forms and ways we use and practice langauge. David Finkelstein, former Director of the School of Physics at the Georgia Institute of Technology, and now at M.I.T. Mathematics, says of the various languages of science that, like English, science is also a language. It is constructed of symbols. And the best you can get with symbols is a maximal but incomplete description. A mathematical analysis of subatomic phenomena, for example, is no better qualitatively than any other symbolic analysis, because symbols do not follow the same rules as experience. They follow rules of their own.
In short, the problem is not in the language, the problem is the language. Our problem, according to Finkelstein, is that we cannot understand subatomic phenomena, or any other kind of experience, through the use of symbols alone. As Heisenberg observed: The concepts initially formed by abstraction from particular situations or experiential complexes acquire a life of their own. Or as I like to observe, science [in its various quests to get to the bottom, top of, or arms around everything] has a cultural challenge: it's biased, for various partially understood reasons, towards familiar cultural methods and symbols, and those biases regard experience only on an evidentiary and verification/validation basis. Hence the methods for "in here" lack the cumulative five hundred (500) years of practice "science" has just put into the methods for "out there", and, again, at least in the West since the time of Heraclitus of Ephesus (some 2500 years ago), science has progressively (that's how it's described) put aside and 'forgotten' ('see' what we 'see') methods for "in here" developed in some instances over millenia. There are an increasing number of anomalies being discovered, buried, ignored or otherwise managed that emphasize science can't "have it's cake and eat it too" AND remain faithfully dichotomous. On present course the 21st century frames a space wherein these methods meet and blend, and in doing so reveal themselves as only symptoms of a far deeper craft and calling.
Some say we make the world, I rather think that as you and others have written here, in the flow of this sense, that we enact and practice it; and perhaps, in a reaching out that reaches in, we might learn to forgo the acts of personal, social and, herein, with respect to science and consensus, professional cultures that forget our deep and seemingly universe-spanning selves.
Arthur C. Clarke opined almost sixty years ago, that in the Year 2000 the Nobel Prize for Physics would be awarded for the "Study of Consciousness" He's off by a few years, however, he's right on target in that I presently think that if modern classical science (dichotomous) is to heal itself, inadvertently, mathematicians, physicists and philosophers will be in the vanguard. As Jung's friend, Nobel Prize-winning physicist, Wolfgang Pauli put it almost three quarters of a century ago: "From an inner centre the psyche seems to move outward, in the sense of an extraversion, into the physical world...If these men are correct, then physics is the study of the structure of consciousness."
