The end of Solvay?

By Saturday, July 5, 2014 1 No tags Permalink 0

I remember first reading about quantum physics with a sense of relief and liberation: the world was not a humean table of billiards, but a probabilistic chaos of possibilities. Now, since I have come to be much less convinced that probabilistic chaos is more free than deterministic order, but at some less reflective level I have always felt that if chance is at the root of things that would be, well, a good thing. Determinism always seemed a dreary proposition. It now turns out that this may have been a temptation shared by the Solvay-conferences dominant flank when they sketched out their view of what the world is based on quantum physics. Einstein famously objected that he felt uncomfortable with the randomness of it all in his comment “God does not play dice” – but Bohr dismissed that with asking that Einstein not tell God what to do. In a new article in Wired we can now read about deterministic accounts of quantum physics, and maybe, just maybe, we learn again that betting against the smartest person in the room is never a good thing to do. We also, however, are back at the drawing table from a philosophical viewpoint: if the world is deterministic – does it matter what we do? Were we determined to ask that question and to then act in a certain way in answering it and drawing our conclusions from it? Is there any space for meaning in an oil-droplet universe? Answers range from Chalmer’s notion of consciousness as a basic force in the universe to an in-depth study of the language games we are playing and how they are related – and why no single one has precedence over any other. A longer discussion. But one that suddenly became more interesting again – as the philosophical ramifications of the deterministic worldview in physics have remained largely unexplored since Solvay.

Notes from Brussels on Plato and Aristotle

By Thursday, July 3, 2014 0 No tags Permalink 0

I arrived in Brussels a few days ago, and am traveling back tonight. The city is in full summer dress, and as I was running through one of the parks I ran past beautiful roses and other flowers, their scent almost creating a separate section of time and space. There is something about scents, about the way in which they catch you off guard. I am here working, but will not bore you with details. It is a formative period in the history of the European Union, a new commission, a new parliament — Europe chooses what it wants to be. It is also a formative time in many member states, where the sorting through the consequences of the European elections in quite a few cases is now shading over into national elections. I follow the reports from friends and others in Almedalen and see that Sweden is in the midst of this transition – the discussions about welfare, tax, xenophobia, immigration, education and health care both intense and wide-ranging. With the events in the Ukraine, defense also finds itself on the agenda, much to the surprise of many who would have expected that this issue would never figure on the national scene in Sweden.

I sat yesterday looking at the view from the terrace at the Sofitel, following the skyline of Brussels, the strange mix of small, old houses and new, very 70s modern architectures melding into one single skyline, interrupted by the occasional church or highrise. There is something about cities, there is something about that way of organizing ourselves that really appeals to me. I am reading a monograph on Aristotle and Plato, and right now the author is discussing their views of politics – the utopian Platonist view (that led to so many disasters when implemented in reality) and the Aristotelian view that starts from the bottom and reasons from the individual. Aristotle, then, is usually thought to be the father of the modern democracy, indeed of modern statecraft and a science of the state. His work on collecting constitutions – pure comparative political science – is one example. And Plato in the meantime has been derided as the philosopher of dictators and monarchs – and indeed that is how he has been used. But it strikes me that there is something both magnificient and tragic in Plato’s view of politics. His visions, myths and ideal models in The Republic and Laws or the Stateman are all societies that start from the assumption of the good man, they all start from this notion that virtue is knowledge. The socratic analysis. Virtue is knowledge, and hence if we build a society that creates knowledge – we will get virtue. When we give up on Plato, we give up on the possibility of creating (through external means) the virtuous man.

And, sure, we may be better off without that idea, without that illusion. But that does not mean that the question Plato forced us to ask was wrong. Plato’s assumption then – read one way – is that if we do not assume virtuous men and women, well, then what we do in politics will always be mitigation and probably useless at that. His quip, that good men do not need good laws, and bad men will ignore good law, is a reductio ad absurdum of the view that we can hope for laws to underpin any ideal society. The battle between Plato and Aristotle, then, becomes not so much the battle between utopianism and democratic realism as it becomes a a battle between the hope for a virtuous man and the fear that virtue is unattainable. We are, thus, perhaps, better off with Aristotle, but that sets a series of important boundary conditions for all political systems and asks that we base them on the assumption of scarcity of virtue.

I think that in one sense that was why Aristotle had to also attack the issue of virtue in the Nicomachean ethics. He needed to find a concept of virtue that was not impossible, but real. The very idea of virtue as the mean is powerful not least because the existence of the extremes prove that there is a virtue, it is real, it is realizable. And then we can build our society on that, not on the ideal man, but on the mean, and – again reading the ethics – on friendship as a fundamental social mechanism.

Then the question becomes: what is the maximum size of social organism that can be constructed with virtue as a mean and friendship as the constituent mechanisms? The city?


Memetics and free speech – a note in the margin

By Sunday, June 22, 2014 1 No tags Permalink 0

What are your views on spreading viruses? Do you believe that spreading viruses is a good thing because it increases the collective immune response of the species, or are you more of the conviction that spreading viruses is malicious and should be, in specific cases, even criminalized as a kind of abuse? Most of us likely end up in the second camp, and I know that I have secretly hoped there is a special circle in hell for those that go back to quickly to school/work/kitchen when they have suffered a bout of winter vomiting disease or the calici-virus.

So, why ask this? Well, I just finished looking at a very old TED-video (you know, the sometimes derided fast food for the mind that can give you world-shaking insights in a few minutes) that really set me thinking. It was a video with one of my all-time favorite philosophers, the unimaginably smart professor Daniel Dennett. His talk was about parasites. He told a story about a parasite that attacks ants, gets them to climb grass in the hope that they will be eaten by cows and there, in the nice and comfy heat of the cow stomach, the parasite can reach its next life stage (career growth!).

The parasite hijacks the ant’s brain and bypasses all genetic imperatives that normally govern how an ant behaves, and turns the ant into a vehicle for its own advancement.

This, Dennett said, is exactly what happens with some ideas as well — ideas that he, following Richard Dawkins, calls memes. These memes are mental parasites that proliferate through human communication and colonize the brains of humans in order to survive. Ideas evolve, survive and die out. Dennett had another interesting example: quakers. Quakers, he said, is a religion that preaches celibacy. For everyone. Not a great evolutionary strategy, one may note. But quakers could recruit enough orphans and outcasts in society to survive – until the modern welfare state put them out of business: not enough misery, and so not enough recruits, and hence they died out. Quakers had – Dennett implies – a mental meme parasite that hijacked them and counteracted all genetic imperatives.

And then he turned to more serious examples: fundamentalist religion being the perhaps most important one. There, more than in any other case, the imperatives of genetic evolution are effectively eliminated and young people willingly die for the sake of an idea. There are many such memes, Dennett noted, a great multitude of ideas to die for.

Slightly worrying.

But so what do we do? Let us assume that the memetic hypothesis – it is not more than that I think – is right. What does memetics then teach us about how we constitutionally should design societies and legal systems?

What about, say, free speech?

Free speech is very much like a right to freely spread viruses, if the memetics hypothesis holds. Anyone can spread any idea, and if that idea takes hold it is fine to let it do so. If we believe that ideas are memes and act like parasites or viruses – do we then believe in free speech?

It is not an easy question. We can imagine a number of different answers that will put us in different kinds of dilemmas.

First, we could argue that we need inoculation to ideas that want us to die for them. The only inoculation that would work, we could say, is education. Education, then, is the key to allowing free speech. Only the educated are allowed to hear free speech, because they have the vaccine of knowledge that allows them not to be smitten by fundamentalism, nationalism or any other ism that wants to kill them. But what levels of education do we need, and how do we proceed with the many billions that have not yet had those levels of education? Should we revoke their right to listen as they are far to easily infected with murderous ideas? And how do you do that, but still educate them?

Second, if we assume this is true and revise our hate speech thinking to actually reflect a ban on ideas that wish that we die for them, ideas that are positively designed to circumvent the evolutionary genetic imperatives or procreation and evolution, what do we then do with non-violent versions of these ideas? The wish to join a monastery circumvents genetic imperatives, but is it harmful? Is it only ideas that want us to die for them that we need to stop? What about patriotism? Altruism? Do we object to ideas of sacrifice if they don’t make evolutionary or genetic sense? “It is logical to sacrifice yourself for two siblings and four cousins…” as someone supposedly said.

Thirdly, if we say memetics has no bearing on free expression, that there simply is no analogy there that is meaningful to explore – then do we really believe in the memetics hypothesis? If we indeed think we are sometimes victims to ideas that infect us, we should probably design our society to give us as good a chance as possible to fight them, should we not?

All this leads me to think that an exploration of a theory of free speech in memetics would be an interesting undertaking, and one that would allow us to cut the many challenges in free speech and free expression in a new way, even if it ends up discarding the analogy because of mismatches and glitches in the metaphors employed. Just a thought. Now, back to what you were doing.

Combinatorial innovation and evolution

By Friday, June 13, 2014 0 No tags Permalink 0

An analogy that has been gaining in popularity these last few years is the idea of “innovation as evolution” — a model that implies that combinations of earlier innovation are what drive innovation not entirely new unheard of technologies suddenly appearing. In a recent paper, “Invention as a Combinatorial Process: Evidence from U.S. Patents” authors Hyejin Youn, Luis M. A. Bettencourt, Deborah Strumsky, Jose Lobo show that this is indeed what innovation looks like. They write:

Arthur and Polak [38] eloquently state the combinatorial view of technological change: “New technologies are never created from nothing. They are constructed – put together – from components that previously exist; and in turn these new technologies offer themselves as possible components – building blocks – for the construction of further new technologies.” (p.23) By using patent technology codes to identify distinct technologies and their combinations we are able to systematically and empirically study the combinatorics of invention. We find that the combination of technologies has indeed been the major driver of invention, reflected in an invariant introduction of new combinations of technologies engendered by patented inventions.

The introduction of new technological functionalities plays a minimal role in fueling invention once the system is mature. Instead, tinkering, gradual modification and refinements are very important in pushing invention forward. (My emphasis)

This is quite interesting and seems to imply that what we should do is to maximize the space for just this: tinkering, gradual modification and refinement. The results are worth examining closely, and we should of course be careful with drawing to far-reaching conclusions, but the method and results at least merit consideration by anyone interested in innovation, and perhaps in creativity overall.

Weil I: on the rights and obligations of free expression

By Thursday, June 12, 2014 0 No tags Permalink 1

I have been meaning to write this post for quite some time now, but something has always gotten in the way. The reason for my interest in Weil and free expression is that I re-read The Need for Roots last summer and was struck by how modern the paradox of free expression in Weil’s thinking is. And her obvious frustration with the law and its inability to handle the tensions she thinks free expression creates is also instructive in many ways of how we in our age are struggling with the very same issues. Weil notes how important it is to be able to think freely and how liberty of thought is fundamental, and:

That is why it would be desirable to create an absolutely free reserve in the field of publication, but in such a way as for it to be understood that the works found therein did not pledge their authors in any way and contained no direct advice for readers. There it would be possible to find, set out in their full force, all the arguments in favour of bad causes. It would be an excellent and salutary thing for them to be so displayed. Anybody could there sing the praises of what he most condemns.

It would be publicly recognized that the object of such works was not to define their authors’ attitudes vis-a-vis the problems of life, but to contribute, by preliminary researches, towards a complete and correct tabulation of data concerning each problem. The law would see to it that their publication did not involve any risk of whatever kind for the author.

On the other hand, publications destined to influence what is called opinion, that is to say, in effect, the conduct of life, constitute acts and ought to be subjected to the same restrictions as are all acts. In other words, they should not cause unlawful harm of any kind to any human being, and above all, should never contain any denial, explicit or implicit, of the eternal obligations towards the human being, once these obligations have been solemnly recognized by law.

The distinction between the two fields, the one which is outside action and the one which forms part of action, is impossible to express on paper in juridical terminology.

But that doesn’t prevent it from being a perfectly clear one.

And here her notion is quite clear. She wants to have two spheres of free expression – one where you explore arguments without holding the views you express, and one where you hold the views you express and can be held to account for them. In the first she wants completely free thought, in the other extreme responsibility.

You can express whatever you want as long as you do not mean it. 

It is easy to ridicule this notion, but there is something very fundamental about this thought that I think permeates also how we think about free expression today. And why is this the case? I think we intuitively realize that we should be free to explore all arguments, but that convincing people or persuading them is a different act than expressing a thought as clearly as possible. Noone would oppose a book that explained the reasoning and thought-processes behind, say, revisionism – but we all feel at some level that an attempt to convince us of a revisionist account of history is different.

There is an emotional gap between expression and persuasion that we are bothered by.

The genius of Weil’s solution is to create a frame, an environment in which there can be only expression and where persuasion is impossible per se. And then to allow anything in this environment. The early cyber-libertarians would have argued that the “new home of mind” was exactly that – that the Internet was this realm of abstract expression where complete freedom should reign. Now we know of the persuasive powers of social media, and we are much more wary of designating the web a separate domain.

At the end Weil acknowledges the tricky challenge of trying to frame this in legislation. It is clear that she realizes that if we want rule of law, we need legislation that expresses the limits of our rights and obligations, but this particular pair of rights and obligations is truly hard to frame in law. Yet still, she argues that it is completely clear. This is where I think she is wrong. Our inability to frame something in legislation actually shows us something about the clarity of the notions in our argument. Sure, there are things that are clear, but hard to frame in law — but when it comes to liberty we are probably wise to assume that if we cannot find the legal form of an argument, then the argument is just half-baked.


Finally, there is a wider point in Weil’s thinking here that I think is sometimes lost in the debate today, and a point that I think actually echoes Hayek in some sense, and that is the connection between a right and an obligation. Weil writes in the beginning of her work that duties or obligation precede rights, and that a sole human being in the universe would have obligations but no rights. Her concept of rights is a complicated one, but essentially she argues that all rights are dependent on obligations of different kinds, on an individual level. The right to express ourselves freely, in her argument, corresponds to the obligation to not try to persuade anyone of what is fundamentally immoral – and she assumes that this is evident for anyone that honestly examines an issue. This of course is an impossibly optimistic view of human nature, but at the same time a sympathetic one to a degree — if we did not know what it could actually lead to.

We could imagine other corresponding obligations, that to me seem more interesting. I had a chance to speak about this a year ago at a TEDx thing in Almedalen, and my thesis there was that the corresponding obligation to the enormous expansion of our individual rights of free speech is an obligation to listen to the growing silences of the growing number of people who are oppressed, quieted and censored  - and act to dissolve these silences, as an individual obligation.

Istället för Turingtestet…

By Wednesday, June 11, 2014 0 No tags Permalink 0

De senaste dagarnas diskussioner om Turingtestet har varit ganska uppfriskande. Inte minst eftersom jag tror att det är viktigt för alla vetenskaper att ha olika sorters fokusproblem. AI har under ganska lång tid kämpat med vad John McCarthy kallade “Ma, look what I can do”-problem som egentligen bara handlar om att återskapa eller imitera olika mänskliga förmågor. Kan datorer spela schack? Kan de spela go? Kan de måla tavlor? Komponera musik? Imitera mänsklig dialog? En efter en har så dessa olika frågor besvarats jakande på olika sätt, och de har alltid utmanats. När Kasparov slogs av datorer var det många som mumlade att det inte var rättvist, och att det minsann inte kunde gått rätt till och att människor trots allt nog är bättre än datorer på schack. I stället för att bara rycka på axlarna och säga att, jaha, intressant – hur kan vi utveckla nya typer av intelligens i stället för att hålla upp det mänskliga intellektet som en sorts idealtyp mot vilken vi alla borde sträva i vår forskning? Och den lika naturlig följdfrågan blir då om det skulle vara möjligt att utforma andra sorters test för utommänsklig intelligens – test som inte handlar om att bara försöka imitera oss? Och hur skulle då dessa se ut? Det är lätt att tänka siog alternativa imitationsspel – som ett där vi bedömer olika deltagares frågor i stället för deras svar, eller där vi bedömer ett nätverk av olika aktörer för att se om det består till huvudsak av människor eller till huvudsak av mjukvara. Vi skulle också kunna säga att en dator måste kunna laga mat, ha tråkigt eller vara bekymrad över en viss given existentiell fråga för att vara intelligent i någon mänsklig mening. Men hur skulle vi kunna testa för alternativa intelligenser? Där är det inte lika lätt att se hur ett fokusproblem skulle kunna arbetas fram, men det vore värdefullt för diskussionen att fundera kring detta, tror jag.

Kanske finns det här ett gränsproblem, det som antyddes av Wittgenstein i den kryptiska kommentaren om lejonens språk. Om ett lejon kunde tala, skrev Wittgenstein, skulle vi inte förstå det. Kanske kan vi inte känna igen eller identifiera en intelligens som inte är mänsklig – annat än ana att det finns något där? Och kanske är universum fyllt av intelligens som vi helt enkelt inte förmår identifiera på grund av våra egna biologiska begränsningar? Skulle detta då ens vara intelligens? Här fingret på en öm punkt – vi har ingen riktigt bra definition på det vi söker här. Det rör sig om något vagt som kretsar mellan begreppen själ-medvetande-intelligens-tanke-upplevelse och som inte riktigt låter sig testas för.

Eller så är det som den gamla berättelsen om domaren och obscentiteten – “I know it when I see it” – en sorts attitydkriterium av det slag som Wittgenstein föreslog. Det är en annan möjlighet. Det finns en mängd intressanta problem här, som det gamla automatproblemet. Hur vet jag att mina medmänniskor inte är maskiner utan medvetande? Turing konstaterar att i den riktningen ligger solipsismens ödemarker. Och i dem kan vi inte testa något alls (men jag har hört att sällskapet är enastående).


Turingtestet – en uppföljning

By Tuesday, June 10, 2014 0 No tags Permalink 0

Som jag postade i en kommentar till streckaren i går förväntade jag mig att det skulle gå fort för nyheten om turingtestet att bli kontroversiell. Idag har jag fått en mängd brev om understreckaren, flera positiva och några negativa. De negativa menar att jag “gått på en mediegroda” eller “inte källgranskat mina påståenden”. Förmodligen menar de då att jag felaktigt säger att Turingtestet nu klarats av, och sannolikt menar de själva att så inte är fallet. Det är intressant av en mängd skäl.

För det första har de tydligen inte läst artikeln, eftersom jag medger att det är lätt att vara skeptisk, och att det finns gott om invändningar. Faktum är att nästan hela artikeln handlar om dessa invändningar och hur Turingtestet själv försökte bemöta dem. Och att testet kanske borde överges.

För det andra är det intressant att se att folk blir så upprörda över att någon påstår att Turingtestet nu kan klaras av. Det kan läsas som en sorts nervositet (någon tweetade på skoj att nu är minsann Skynet nära) eller som en grav överskattning av Turingtestet. Och det är nästan ännu mer intressant. Turings test är ett imitationsspel och inte något annat. Datorer av olika slag har klarat av det massor av gånger under olika villkor, redan med mjukvarupsykologen Eliza agerade patienter som om de kunde anförtro den imiterade psykologen sina hemligheter och efter det finns det massor av exempel på program som klarat av Turingtestet under vissa omständigheter. Som jag skriver i artikeln kan vi välja att ändra parametrarna tid och procentandelen som tar mjukvaran för mänskliga, men det ändrar inte sakförhållandena. Turingtestet är ett test på ett programs förmåga att imitera människor. Det gör de tillräckligt bra idag för att vi skall kunna säga att det nu kan läggas till handlingarna – och utan att några särskilda slutsatser kan dras om datorers intelligens, egentligen.

För det tredje finns det en oroväckande slapphet i den källkritiska granskningen. Många har bara skickat länken till en artikel som hävdar att Turingtestet inte passerats utan att läsa denna artikel. Artikeln baserar sig på ad hominem -angrepp på någon som jag är ganska säker på att mejlförfattarna inte tagit sig tid att granska (det står ju på internet att han är en knäppskalle!). Vad vi ser här är framväxten av en klicktivistisk mediekritik, en där det räcker att hitta en artikel som motsäger en annan för att man skall stolt säga att man vederlagt något. Så funkar det förstås inte. Om man hittar två varandra motsägande artiklar får man fundera själv: och det var därför jag skrev mer än tre fjärdedelar av artikeln om just skepsis och invändningar. Det är förfärande hur många som med en länk och litet handviftande tror att de bedrivit källkritik.

För det tredje är det intressant att de flesta inte tycks ha läst artikeln till slut. Min huvudpoäng har varit, och är, att Turingtestet inte är ett intressant test längre. Imiterandes av mänsklig intelligens begränsar forskningen i artificiell intelligens på ett olyckligt sätt och bör upphöra. Vilket jag skriver tydligt i artikelns sista stycke.

Nå, hur är det då? Anser jag att Turingtestet klarats av? Ja, det gör jag faktiskt – ur båda de dimensioner som jag nämner: programvara kan imitera människor tillräckligt bra för att lura en del av oss viss tid och testet har spelat ut sin roll som milstolpe i den artificiella intelligensforskningen. Kvar ligger gåtan om medvetandet, frågor om hur vi interagerar med artificiell intelligens och vilka andra milstolpar vi bör sätta upp.

Nu ska jag fundera på om man inte skall skriva en artikel om debunking som nytt källkritiskt problem: det okritiska accepterandet av motfakta baserat på endast existensen av dessa motfakta, och den obehagliga viljan till förenkling. Intressant, eller hur?
