On the scope and limits of science

This essay was first published under the title Self-Expression, Knowledge and Value at The Electric Agora.



Attempts to express a comprehensive personal view of the world are doomed to failure. Each of us has a view of the world; some such views are more developed and plausible than others. But language (even supplemented with other modes of expression) is simply not equipped to articulate the complex and shifting set of values and beliefs which creates and lies behind the way a particular individual sees and interprets the world.

What we can do is to express our views on and reactions to particular topics and particular things. What we can’t do is to tie it all together and articulate the whole, even in general terms.

There are a number of ways of looking at this. You could see it in terms of underlying logical coherence, for example. If a view of things had such coherence, it could be articulated accurately and concisely, at least in general terms. (1) But, given the fact that conscious reasoning constitutes only a minuscule portion of cognitive activity, there is no reason to expect – and every reason not to expect – that a person’s outlook on the world, with all its implicit value assessments, etc., would have anything like the degree of underlying logical coherence which would be necessary for its satisfactory articulation in linguistic terms.

Another way of looking at this is in terms of frameworks. A particular context is always required to provide a foundation for any statement or claim, and there is no general or generic context to which we can appeal. The broader the context, the less we can usefully (or even meaningfully) say. The danger here is that one gets lost in virtually meaningless abstractions and generalizations.

The most powerful forms of self-expression via written language are literary, and good writing in a literary sense is marked by specificity and concreteness and attention to the details of lived experience. Generalized claims and abstractions play only a minor role.

The impulse to express a comprehensive view has traditionally manifested itself in religious and philosophical contexts. But, as ways of understanding the world, modern scientific disciplines (including historical disciplines) have largely replaced religion and traditional metaphysics. You want to know about some specific thing? Go to the experts. Unfortunately, there are no experts to go to if you want answers to substantive questions about values or about the significance of human life, for example.

Individually we need to be committed to a set of values and beliefs in order to live. There is a huge range of possible belief and value systems, but an individual’s social and cultural environment narrows the possibilities somewhat. Beyond embracing the best available cultural elements (as one sees them) and applying principles of practical wisdom and commonsense, there is not a lot more one can do, other than ensuring that – as far as possible – one’s beliefs are compatible with scientific and scholarly knowledge.

It has become clear over time that scientific, empirical, formal and analytical methods represent the only reliable ways we have of building an objective or value-neutral communal knowledge base. Unlike our culturally-driven (and so values-driven) individual perspectives, this knowledge base is not only able to be articulated, it only exists to the extent that it has been articulated. It is necessarily public knowledge. (I use the word knowledge, but all claims are subject to challenge within the context of the disciplinary processes involved.)

Even here, however, the knowledge in question does not constitute a single thing or a unified structure, and so cannot be expressed concisely or in a unified way.

The term “edifice” is sometimes used to describe our communal knowledge base, but this metaphor is very misleading. In fact, it seems to me that one of the most significant things about human knowledge which the history of science and rigorous scholarship clearly demonstrates is its diverse and distributed nature. It is something of an irony therefore that champions of a scientific view of the world so often fall into the trap of seeing knowledge in unified terms.

Otto Neurath, who represented what might be called the radical wing of the logical positivist movement, was for many years the most prominent promoter of the notion of the Unity of Science. He clashed repeatedly with moderate figures in the movement such as Louis Rougier who strenuously rejected the notion, seeing in Neurath’s campaign an attempt to promote a creed, a new orthodoxy. Neurath’s view was an updated version of well-known 19th-century attempts to create a scientific socialism, and it was quite as censorious and illiberal as traditional religious orthodoxies, if not more so.

The attempt to promote a scientific creed continues to this day, of course, driven by a combination of arrogance and ignorance of intellectual history. But there is a difference between having a basically scientific view of the world and making science into some kind of creed or orthodoxy.

Things have changed in the arts and in non-scientific intellectual circles in recent decades, but not so long ago many of the greatest writers and artists and non-scientific thinkers had a very positive view of science, or at least accepted the general findings of mainstream science and rigorous scholarship. This is sometimes forgotten, partly because many of these writers and thinkers are currently out of fashion but partly also because the scientific or science-accepting side of many currently fashionable thinkers (Nietzsche comes to mind) is being downplayed.

As I see it, the fruits of science and scholarship belong to us all even though, as individuals, our actual knowledge is necessarily limited. Strangely enough, practicing scientists and scholars – because of the extreme degree of specialization which is required today – are no more likely to have a satisfactory general understanding than the interested observer, and the amateur will often have more time and energy than the specialist to devote to wide reading and to considering the implications of what is known.

I still have a very high regard for leading thinkers in scientific fields, especially fields (like physics and biology) which deal with fundamental questions of the natural world which have a bearing on how one sees or conceptualizes human life. But the more one reads their popular books or blogs or listens to interviews or to panel discussions, the more obvious it becomes that the special insights of scientific specialists rarely go beyond the scope of their areas of expertise.

For most purposes, of course, specialist expertise is not required, and useful or interesting conclusions can be drawn from very basic kinds of knowledge. Such arguments and elaborations may (and should, in my opinion) still be rooted in a view of the world which respects the findings of mainstream science and other rigorous forms of intellectual inquiry, but any argument involving matters of human significance (and so human values) necessarily goes beyond science and our empirical knowledge base more generally.

Some such elaborations have been developed with a view to expressing in a systematic way a particular view of the world. These (if my thesis is correct) cannot succeed. I have in mind, in particular, the sort of metaphysical systematizing which was in vogue in Europe, especially during 19th century.

Under the influence of thinkers such as Bertrand Russell and Gottlob Frege, more analytic and narrowly focused approaches gradually came to prominence and largely replaced traditional metaphysics. This analytical strand of philosophical thinking was very different in nature to almost all philosophical thinking before it in that it sought to bring academic philosophy more into line with scientific, formal and rigorous empirical disciplines; in other words to separate once and for all philosophy as an intellectual discipline from more traditional notions which saw philosophy as (at least potentially) providing guidance for living. Both Frege and Russell saw themselves as men of science (in the old European sense of the term). Russell was particularly scornful of the idea that academic philosophy should deal in any way with what was (and still is) popularly known as a “philosophy of life.”

In his intellectual autobiography Russell described the sense of freedom and liberation that accompanied his rejection of the idealist metaphysics which dominated the intellectual world in which he grew up for a more empirically-based view of things. The case I am making here is very much in line with a Russellian view. (2)

A great strength of Bertrand Russell as a thinker is that he was always aware of the way our personal values play into our thinking. Much of his published work is journalistic and opinionated. Arguably his views on education and some social questions were quite misguided. His views on power and politics still stand up, I think. But my point is that he drew a clear distinction between his serious philosophical work (from which he sought entirely to exclude his personal values) and the rest.

My focus here, however, is not science or the nature of philosophy, but rather on the relationship between science (broadly interpreted) and human values. Any attempt to articulate a value-driven point of view takes us beyond a purely scientific or rigorously scholarly space, albeit not entirely beyond the reach of scientific and scholarly expertise.

Even in the realm of rhetoric and persuasion, where personal values hold sway, the compatibility of any given position with mainstream science and rigorous scholarship remains an important litmus test. If a position or point of view fails the test, it can be excluded from consideration. But – fortunately or unfortunately – the bar is fairly low here, and the test in question lets through a vast array of mutually incompatible points of view.

The perspective I am putting forward is based in part on a particular interpretation of recent Western intellectual history. Certain thinkers have influenced me more than others, and any elaboration or defense of these ideas would necessarily involve the historical aspect: arguments about particular thinkers and about the relative merits of different ways of identifying and framing the main questions. (3)

Nonetheless, let me try to sum up my key points in purely non-historical terms. As individuals we slowly develop (or allow the ambient culture to develop for us) a general perspective or view of the world. Such a perspective cannot be fully articulated or satisfactorily summarized. It could be seen to express itself (via words and actions) in countless choices. These choices are practical and action-oriented rather than theoretical. They are responses to particular situations. Whereas individual perspectives can never be articulated holistically, values-based points of view on particular issues (which are driven in large part by an individual’s general perspective) can be articulated. They may be falsifiable, but are not amenable to positive scientific or academic validation.


NOTES

1. There may be a parallel here with the way complexity is conceptualized in algorithmic information theory, i.e. in terms of the compressibility of strings or other kinds of data structure. Data can usually be compressed (to a greater or lesser extent), but arbitrary random data cannot.

2. I am also drawing on Karl Popper’s general views on knowledge and falsifiability. Many of Russell’s and Popper’s specific views have been called into question, of course, and/or developed in various directions. Russell (at least) welcomed this. He saw himself as having made his significant contributions relatively early in his life and looked to others (initially to Ludwig Wittgenstein, and later to the logical empiricists) to move things forward. It is often asserted that the logical positivist movement 1) failed and 2) deserved to fail because the core insights of its main representatives were profoundly misguided. I question both of these judgments. Some of the ideas which drove the logical positivists were misguided. I mentioned Neurath’s ideologically-driven approach, for example. But the basic principles and perspectives on the scope and nature of human knowledge expressed in the writings of more moderate figures within the movement (like Moritz Schlick, Hans Reichenbach and Louis Rougier) are sound, and I am optimistic that they will survive – at least in modified forms which reflect ongoing changes in the scientific and intellectual landscape.

3. Also, it is obvious that the general perspective on knowledge which I have been discussing (and defending) has social implications. Historically speaking, it has, by and large, been associated with anti-totalitarian social philosophies, and this is no accident. I would want to claim (though I am not attempting to make the case here) that such a perspective is naturally compatible with traditional liberal values and – if not strictly incompatible with – at least not supportive of extremist politics, either of the left or the right.

History and truth

At The Electric Agora, E. John Winner reflected recently on a tragic – and relatively late – episode in the long history of the destruction of Native American culture and society: the Battle (or Massacre) of Wounded Knee. I have only a general sense of the history involved here, but the basic themes will be familiar to anyone who has lived in a colony or former colony or has knowledge of European colonialism.

What many people don't realize is that in many cases the main actors on the European side saw their actions in positive and idealistic terms. I know a bit about British colonial activity during the 18th and 19th centuries and, if you read the letters and reports of the people involved (administrators, professionals, etc.), the sense of responsibility and moral seriousness is often palpable. Certainly they saw what they were doing in very different terms from how we tend to see it today.

That said, in most cases they underestimated the complexity and sophistication of the indigenous cultures with which they came into contact and which in many cases were almost totally destroyed.

There is, I think, a general acceptance that politics – and especially geopolitics – doesn't actually work according to principles of justice; in other words, that wealth, technology and ultimately force are more important driving forces. Consequently, claims based on moral or justice-related grounds are often seen in rhetorical and political terms. They may not even necessarily be believed in (in any real sense) by those initiating or promoting the claims. Claims based on generalized notions of justice (and especially on notions of social justice) are often wielded merely as political weapons.

My own inclination in dealing with historical narratives is to try not to expropriate them for political purposes, because this inevitably leads to distortion. The aim becomes not so much to understand what happened as to find or develop a politically effective narrative, to have a useful story. The story is judged not according to criteria such as balance or truth (i.e. whether it derives from a plausible interpretation of available primary sources) but rather in terms of perceived usefulness for bringing about a desired political outcome.

I am more comfortable dealing with terms like "probity", "decency", "cruelty" and "betrayal" than with more abstract and generalized concepts (like "justice" or "social progress"). The former can often be read out of primary sources fairly directly. By contrast, the latter – more often than not – are read into such sources by historians or activists who have their own preconceived ideas about what justice or social progress is or should look like.

We come to terms with the past only to the extent that we understand it. And understanding history inevitably involves being open to a range of (often conflicting) perspectives or points of view.

Justice, injustice and truth

What follows is a short extract from an essay of mine which was published earlier this month at The Electric Agora on truth and justice. In this passage, I raise a couple of logical and linguistic points about justice (relating to negation and markedness), as well as noting the asymmetry between the concepts justice and truth (the former being dependent on the latter, but not the latter on the former).


[...] Just as the positive rights implicit in social justice are more controversial and contested than negative rights (like liberty), so the concept of justice is (I would suggest) more problematic than the concept of injustice or of a miscarriage of justice. You could argue about whether a person guilty of a crime, for example, ought to be punished in this way or that or punished at all or even blamed. (There might have been extenuating circumstances.) But there would be no disagreement at all about the wrongness of a miscarriage of justice, where a person innocent of a particular crime was convicted; or with respect to cases of a broadly similar kind but which do not involve the court system (so that the term miscarriage of justice would not apply). With respect to the latter, I am thinking of situations – not hard to find, it must be said – in which a person is disadvantaged or penalized in some significant way for what is generally accepted as honest and exemplary behavior.

Another point that seems interesting to me here pertains to the linguistic concept of markedness. Markedness phenomena crop up in many linguistic contexts, like grammatical gender for example. Feminine nouns and adjectives often derive and take their core meaning from the unmarked masculine form. (A suffix might be added to signify a feminine noun or adjective.) Markedness can also apply to antonyms and negation. But it seems that certain negative forms are more uncontroversial and may be clearer than their positive equivalents. This is slightly odd given that the marked negative form of an expression (like ‘injustice’) is in a real sense dependent on and derives its meaning from the unmarked positive form (‘justice’). How is it then that cases of injustice can be more readily understood and less controversial than questions of justice? It is as though the semantics is pulling in one direction (making ‘injustice’ the primary term) and morphology and syntax in another.

Note also that the two concepts, truth and justice, are not symmetrically related. Truth relates directly to justice. The legal process is designed to uncover the truth of what happened, and perjury is a serious offense. One talks of someone being falsely accused. But justice doesn’t relate directly to questions of truth and falsity. Claims are true or false according entirely to non-justice-related criteria. Justice (or injustice) just doesn’t come into it.

Update


I have been neglecting this and my other Blogger site and concentrating on writing essays for Dan Kaufman's Electric Agora and (usually) posting shorter versions (plus links) to my G+ collections. I had intended to crosspost relevant essays here but haven't been doing this. I will be doing so in the future, however.

Over the past couple of years I have written quite a lot of material, and my essays have attracted a bit of attention and garnered about 1500 comments in total.

The Electric Agora is not my site, however, and I don't have any control over it: over whether or in what form it continues, for example.
So I am thinking that I could use this site to bring together (possibly in revised form and/or with a view to reworking them) all of my relevant pieces from the EA (and elsewhere).

Again, one has no control over how particular platforms such as Blogger or G+ are going to develop (if indeed they continue), nor of course can one predict with any confidence how the general informational and communicational landscape is going to evolve in the future.

My intention is just to stick to the sites I currently have or contribute to.

Including my Twitter account... @mark_english1.

Arguments about existence

I haven't been posting here lately, even to the extent of linking to articles of mine which are being published at The Electric Agora. My most recent article at the EA was a response to some claims that Daniel Kaufman had been making about the existence of things like selves and agreements. He was making more of the "existence" of these things than I would, and was attempting to set up what I see as a false dichotomy between the physical sciences on the one hand and the social sciences and humanities on the other. He doesn't believe that evolutionary biology or neuropsychology, for example, have a lot to tell us about social reality.

As is usual at the site, there was quite a good discussion in the comments section. But whether this discussion goes any further will probably depend on whether Dan continues to publish pieces on this particular question. He may do, as he indicated that he was planning to write a book on the subject.

Brutal reality?

[Recently posted to my Google+ collection Language, Logic, Life.]

Dan Kaufman recently got a bit of flak (even from his wife apparently) for his energetic critique of the new – or continuing – 'cult of the self'.

"... [T]he old Cult of the Self [the reference here is to the 1970s and '80s and such movements as Werner Erhard's 'est' program] actually may have been slightly less loathsome than its newer, smarmier versions, insofar as it was at least honest, albeit in a brutal, tone-deaf sort of way."

He is saying that the older movements did not really disguise their egoistic nature whereas more recent iterations – while still basically egoistic – present themselves as being driven by humane motives.

"... [T]oday’s Cult of the Self represents itself as being socially oriented, and with social media having trained us to accept the thinnest, most indirect, heavily mediated interactions as constituting real relationships, it’s easy to convince ourselves that seeing others entirely through the lens of our own well-being and virtue constitutes genuine connection and concern, rather than self-absorption masquerading as such.  Gone is the idea that our deepest relationships with and obligations to others are properly self-effacing, and in its place is the notion that the main thing to think about, with respect to other people and what they deserve, is how the way I treat them reflects upon me."

....

I commented (in part) as follows:

"My default position is that something like that "brutal" position is probably 'true' in the sense that it correlates well with reality. But this could be seen as a dangerous idea. It seems to me there is a key divide here on how people see the world (and themselves). I don't know, however, that I would want to push this idea too much: social consequences may not be good. There is no reason to think that just because something is true, it is something one should talk about. I've never liked the 'noble lie' idea, but reticence is slightly different from this. Reticence – like lying, actually – is ... something I am not particularly good at, however."

I also suggested in the comment that Max Stirner's radical egoism – which Leszek Kolakowski saw as prefiguring fascism – was an important precursor to the movements Dan Kaufman was attacking.

In due course I will try to expand on these somewhat cryptic remarks. It could form the basis for a new Electric Agora article (or articles). But let me here and now try to put the core idea more directly.

I am suggesting that the standard way of seeing things involves a lot of self-deception and (to use a loaded term which may or may not be appropriate here) hypocrisy.

Fundamentally the social world works just like the natural world described by biologists. Evolutionary processes are not pretty. Having language and culture adds complexity and richness and gives us freedoms and possibilities which other animals do not have. But it does not allow us to escape this world of deception, manipulation and struggle. A basic kind of ethics and very basic notions of rights and responsibilities make sense: as individuals we survive longer and prosper when we cooperate. But a Christian or socialist-style ethic – based on a kind of generalized altruism (or generosity) mixed with self-denial and deemed to be in some sense obligatory – is problematic, both in terms of its consequences for those individuals (very few, it must be said) who sincerely and seriously try to implement such an ethic in their lives, and in terms of rational motivation.

Still a bit cryptic perhaps. But it is an attempt at least to clarify (in my own mind as well as in a more public sense) the supposedly "dangerous" idea I was talking about not talking about!

The trivial isn't necessarily trivial

[Recently posted to my Google+ collection, Language, Logic, Life.]  At one point in John le CarrĂ©'s early classic, The Spy Who Came in from the Cold, Alec Leamas, a British secret service agent, is staying on the Dutch coast, waiting for an important and fateful meeting. His thoughts turn to a woman who had looked after him when he had became ill in a rented room in London. Liz had been a member of the Communist Party in Britain and so technically opposed to Leamas's cause.

"... At about eleven o'clock the next morning [Leamas] decided to go out for a walk along the front, bought some cigarettes and stared dully at the sea.

"There was a girl standing on the beach throwing bread to the seagulls. Her back was turned to him. The sea wind played with her long black hair and pulled at her coat, making an arc of her body, like a bow strung towards the sea. He knew then what it was that Liz had given him; the thing that he would have to go back and find if ever he got home to England: it was the caring about little things – the faith in ordinary life; the simplicity that made you break up a bit of bread into a paper bag, walk down to the beach and throw it to the gulls. It was this respect for triviality which he had never been allowed to possess; whether it was bread for the seagulls or love, whatever it was he would go back and find it ..."

Le Carré seems to be suggesting that the real meaning of life is not to be found in causes and grand designs but in the mundane, apparently pointless details of ordinary life. It is very tempting to go along with this line of thinking.
