Cosmopolitanism and the Local in Science and Nature (a three year Canadian project nearing its end date)

Working on a grant from Canada’s Social Sciences and Humanities Research Council (SSHRC), the  Cosmopolitanism and the Local in Science and Nature project has been establishing a ‘cosmopolitanism’ research network that critiques the eurocentric approach so beloved of Canadian academics and has set up nodes across Canada and in India and Southeast Asia.

I first wrote about the project in a Dec. 12, 2014 posting which also featured a job listing. It seems I was there for the beginning and now for the end. For one of the project’s blog postings in its final months, they’re profiling one of their researchers (Dr. Letitia Meynell, Sept. 6, 2017 posting),

1. What is your current place of research?

I am an associate professor in philosophy at Dalhousie University, cross appointed with gender and women studies.

2. Could you give us some details about your education background?

My 1st degree was in Theater, which I did at York University. I did, however, minor in Philosophy and I have always had a particular interest in philosophy of science. So, my minor was perhaps a little anomalous, comprising courses on philosophy of physics, philosophy of nature, and the philosophy of Karl Popper along with courses on aesthetics and existentialism. After taking a few more courses in philosophy at the University of Calgary, I enrolled there for a Master’s degree, writing a thesis on conceptualization, with a view to its role in aesthetics and epistemology. From there I moved to the University of Western Ontario where I brought these three interests together, writing a thesis on the epistemology of pictures in science. Throughout these studies I maintained a keen interest in feminist philosophy, especially the politics of knowledge, and I have always seen my work on pictures in science as fitting into broader feminist commitments.

3. What projects are you currently working on and what are some projects you’ve worked on in the past?

4. What’s one thing you particularly enjoy about working in your field?

5. How do you relate your work to the broader topic of ‘cosmopolitanism and the local’?

As feminist philosophers have long realized, having perspectives on a topic that are quite different to your own is incredibly powerful for critically assessing both your own views and those of others. So, for instance, if you want to address the exploitation of nonhuman animals in our society it is incredibly powerful to consider how people from, say, South Asian traditions have thought about the differences, similarities, and relationships between humans and other animals. Keeping non-western perspectives in mind, even as one works in a western philosophical tradition, helps one to be both more rigorous in one’s analyses and less dogmatic. Rigor and critical openness are, in my opinion, central virtues of philosophy and, indeed, science.

Dr. Maynell will be speaking at the ‘Bridging the Gap: Scientific Imagination Meets Aesthetic Imagination‘ conference Oct. 5-6, 2017 at the London School of Economics,

On 5–6 October, this 2-day conference aims to connect work on artistic and scientific imagination, and to advance our understanding of the epistemic and heuristic roles that imagination can play.

Why, how, and when do scientists imagine, and what epistemological roles does the imagination play in scientific progress? Over the past few years, many philosophical accounts have emerged that are relevant to these questions. Roman Frigg, Arnon Levy, and Adam Toon have developed theories of scientific models that place imagination at the heart of modelling practice. And James R. Brown, Tamar Gendler, James McAllister, Letitia Meynell, and Nancy Nersessian have developed theories that recognize the indispensable role of the imagination in the performance of thought experiments. On the other hand, philosophers like Michael Weisberg dismiss imagination-based views of scientific modelling as mere “folk ontology”, and John D. Norton seems to claim that thought experiments are arguments whose imaginary components are epistemologically irrelevant.

In this conference we turn to aesthetics for help in addressing issues concerning scientific imagination-use. Aesthetics is said to have begun in 1717 with an essay called “The Pleasures of the Imagination” by Joseph Addison, and ever since imagination has been what Michael Polyani called “the cornerstone of aesthetic theory”. In recent years Kendall Walton has fruitfully explored the fundamental relevance of imagination for understanding literary, visual and auditory fictions. And many others have been inspired to do the same, including Greg Currie, David Davies, Peter Lamarque, Stein Olsen, and Kathleen Stock.

This conference aims to connect work on artistic and scientific imagination, and to advance our understanding of the epistemic and heuristic roles that imagination can play. Specific topics may include:

  • What kinds of imagination are involved in science?
  • What is the relation between scientific imagination and aesthetic imagination?
  • What are the structure and limits of knowledge and understanding acquired through imagination?
  • From a methodological point of view, how can aesthetic considerations about imagination play a role in philosophical accounts of scientific reasoning?
  • What can considerations about scientific imagination contribute to our understanding of aesthetic imagination?

The conference will include eight invited talks and four contributed papers. Two of the four slots for contributed papers are being reserved for graduate students, each of whom will receive a travel bursary of £100.

I wonder if they’ll be rubbing shoulders with Angelina Jolie? She is slated to be teaching there in Fall 2017 according to a May 23, 2016 news item in the Guardian (Note: Links have been removed),

The Hollywood actor and director has been appointed a visiting professor at the London School of Economics, teaching a course on the impact of war on women.

From 2017, Jolie will join the former foreign secretary William Hague as a “professor in practice”, the university announced on Monday, as part of a new MSc course on women, peace and security, which LSE says is the first of its kind in the world.

The course, it says, is intended to “[develop] strategies to promote gender equality and enhance women’s economic, social and political participation and security”, with visiting professors playing an active part in giving lectures, participating in workshops and undertaking their own research.

Getting back to ‘Cosmopolitanism’, some of the principals organized a summer 2017 event (from a Sept. 6, 2017 posting titled: Summer Events – 25th International Congress of History of Science and Technology),

CosmoLocal partners Lesley Cormack (University of Alberta, Canada), Gordon McOuat (University of King’s College, Halifax, Canada), and Dhruv Raina (Jawaharlal Nehru University, India) organized a symposium “Cosmopolitanism and the Local in Science and Nature” as part of the 25th International Congress of History of Science and Technology.  The conference was held July 23-29, 2017, in Rio de Janeiro, Brazil.  The abstract of the CosmoLocal symposium is below, and a pdf version can be found here.

Science, and its associated technologies, is typically viewed as “universal”. At the same time we were also assured that science can trace its genealogy to Europe in a period of rising European intellectual and imperial global force, ‘going outwards’ towards the periphery. As such, it is strikingly parochial. In a kind of sad irony, the ‘subaltern’ was left to retell that tale as one of centre-universalism dominating a traditionalist periphery. Self-described ‘modernity’ and ‘the west’ (two intertwined concepts of recent and mutually self-supporting origin) have erased much of the local engagement and as such represent science as emerging sui generis, moving in one direction. This story is now being challenged within sociology, political theory and history.

… Significantly, scholars who study the history of science in Asia and India have been examining different trajectories for the origin and meaning of science. It is now time for a dialogue between these approaches. Grounding the dialogue is the notion of a “cosmopolitical” science. “Cosmopolitics” is a term borrowed from Kant’s notion of perpetual peace and modern civil society, imagining shared political, moral and economic spaces within which trade, politics and reason get conducted.  …

The abstract is a little ‘high falutin’ but I’m glad to see more efforts being made in  Canada to understand science and its history as a global affair.

Multi-level thinking in science—the art of seeing systems

I’ve quickly read Michael Edgeworth McIntyre’s paper on multi-level thinking and find it provides fascinating insight and some good writing style (I’ve provided a few excerpts from the paper further down in the posting).

Here’s more about the paper from an Aug. 17, 2017 Institute of Atmospheric Physics, Chinese Academy of Sciences press release on EurekAlert,

An unusual paper “On multi-level thinking and scientific understanding” appears in the October issue of Advances in Atmospheric Sciences. The author is Professor Michael Edgeworth McIntyre from University of Cambridge, whose work in atmospheric dynamics is well known. He has also had longstanding interests in astrophysics, music, perception psychology, and biological evolution.

The paper touches on a range of deep questions within and outside the atmospheric sciences. They include insights into the nature of science itself, and of scientific understanding — what it means to understand a scientific problem in depth — and into the communication skills necessary to convey that understanding and to mediate collaboration across specialist disciplines.

The paper appears in a Special Issue arising from last year’s Symposium held in Nanjing to commemorate the life of Professor Duzheng YE, who was well known as a national and international scientific leader and for his own wide range of interests, within and outside the atmospheric sciences. The symposium was organized by the Institute of Atmospheric Physics (IAP), Chinese Academy of Sciences, where Prof. YE had worked nearly 70 years before he passed away. Upon the invitation of Prof. Jiang ZHU, the Director General of IAP, also the Editor-in-Chief of Advances in Atmospheric Sciences (AAS), Prof. McIntyre agreed to contribute a review paper to an AAS special issue commemorating the centenary of Duzheng YE’s birth. Prof. YE was also the founding Editor-in-Chief of this journal.

One of Professor McIntyre’s themes is that we all have unconscious mathematics, including Euclidean geometry and the calculus of variations. This is easy to demonstrate and is key to understanding not only how science works but also, for instance, how music works. Indeed, it reveals some of the deepest connections between music and mathematics, going beyond the usual remarks about number-patterns. All this revolves around the biological significance of what Professor McIntyre calls the “organic-change principle”.

Further themes include the scientific value of looking at a problem from more than one viewpoint, and the need to use more than one level of description. Many scientific and philosophical controversies stem from confusing one level of description with another, for instance applying arguments to one level that belong on another. This confusion can be especially troublesome when it comes to questions about human biology and human nature, and about what Professor YE called multi-level “orderly human activities”.

Related to all these points are the contrasting modes of perception and understanding offered by the brain’s left and right hemispheres. Our knowledge of their functioning has progressed far beyond the narrow clichés of popular culture, thanks to recent work in the neurosciences. The two hemispheres automatically give us different levels of description, and complementary views of a problem. Good science takes advantage of this. When the two hemispheres cooperate, with each playing to its own strengths, our problem-solving is at its most powerful.

The paper ends with three examples of unconscious assumptions that have impeded scientific progress in the past. Two of them are taken from Professor McIntyre’s main areas of research. A third is from biology.

Here’s a link to and a citation for the paper,

On multi-level thinking and scientific understanding by Michael Edgeworth McIntyre. Advances in Atmospheric Sciences October 2017, Volume 34, Issue 10, pp 1150–1158 DOI: https://doi.org/10.1007/s00376-017-6283-3

This paper is open access.

To give you a sense of his writing and imagination, I’ve excerpted a few paragraphs from p. 1153 but first you need to see this .gif (he provides a number of ways to watch the .gif in his text but I think it’s easier to watch the copy of the one he has on his website),

Now for the excerpt,

Here is an example to show what I mean. It is a classic in experimental psychology, from the work of Professor Gunnar JOHANSSON in the 1970s. …

As soon as the twelve dots start moving, everyone with normal vision sees a person walking. This immediately illustrates several things. First, it illustrates that we all make unconscious assumptions. Here, we unconsciously assume a particular kind of three-dimensional motion. In this case the unconscious assumption is completely involuntary. We cannot help seeing a person walking, despite knowing that it is only twelve moving dots.

The animation also shows that we have unconscious mathematics, Euclidean geometry in this case. In order to generate the percept of a person walking, your brain has to fit a mathematical model to the incoming visual data, in this case a mathematical model based on Euclidean geometry. (And the model-fitting process is an active, and highly complex, predictive process most of which is inaccessible to conscious introspection.)

This brings me to the most central point in our discussion. Science does essentially the same thing. It fits models to data. So science is, in the most fundamental possible sense, an extension of ordinary perception. That is a simple way of saying what was said many decades ago by great thinkers such as Professor Sir Karl POPPER….

I love that phase “unconscious mathematics” for the way it includes even those of us who would never dream of thinking we had any kind of mathematics. I encourage you to read his paper in its entirety, which does include a little technical language in a few spots but the overall thesis is clear and easily understood.

A question of consciousness: Facebotlish (a new language); a July 5, 2017 rap guide performance in Vancouver, Canada; Tom Stoppard’s play; and a little more

This would usually be a simple event announcement but with the advent of a new, related (in my mind if no one else’s) development on Facebook, this has become a roundup of sorts.

Facebotlish (Facebook’s chatbots create their own language)

The language created by Facebook’s chatbots, Facebotlish, was an unintended consequence—that’s right Facebook’s developers did not design a language for the chatbots or anticipate its independent development, apparently.  Adrienne LaFrance’s June 20, 2017 article for theatlantic.com explores the development and the question further,

Something unexpected happened recently at the Facebook Artificial Intelligence Research lab. Researchers who had been training bots to negotiate with one another realized that the bots, left to their own devices, started communicating in a non-human language.

In order to actually follow what the bots were saying, the researchers had to tweak their model, limiting the machines to a conversation humans could understand. (They want bots to stick to human languages because eventually they want those bots to be able to converse with human Facebook users.) …

Here’s what the language looks like (from LaFrance article),

Here’s an example of one of the bot negotiations that Facebook observed:Bob: i can i i everything else . . . . . . . . . . . . . .
Alice: balls have zero to me to me to me to me to me to me to me to me to
Bob: you i everything else . . . . . . . . . . . . . .
Alice: balls have a ball to me to me to me to me to me to me to me
Bob: i i can i i i everything else . . . . . . . . . . . . . .
Alice: balls have a ball to me to me to me to me to me to me to me
Bob: i . . . . . . . . . . . . . . . . . . .
Alice: balls have zero to me to me to me to me to me to me to me to me to
Bob: you i i i i i everything else . . . . . . . . . . . . . .
Alice: balls have 0 to me to me to me to me to me to me to me to me to
Bob: you i i i everything else . . . . . . . . . . . . . .
Alice: balls have zero to me to me to me to me to me to me to me to me to

It is incomprehensible to humans even after being tweaked, even so, some successful negotiations can ensue.

Facebook’s researchers aren’t the only one to come across the phenomenon (from LaFrance’s article; Note: Links have been removed),

Other AI researchers, too, say they’ve observed machines that can develop their own languages, including languages with a coherent structure, and defined vocabulary and syntax—though not always actual meaningful, by human standards.

In one preprint paper added earlier this year [2017] to the research repository arXiv, a pair of computer scientists from the non-profit AI research firm OpenAI wrote about how bots learned to communicate in an abstract language—and how those bots turned to non-verbal communication, the equivalent of human gesturing or pointing, when language communication was unavailable. (Bots don’t need to have corporeal form to engage in non-verbal communication; they just engage with what’s called a visual sensory modality.) Another recent preprint paper, from researchers at the Georgia Institute of Technology, Carnegie Mellon, and Virginia Tech, describes an experiment in which two bots invent their own communication protocol by discussing and assigning values to colors and shapes—in other words, the researchers write, they witnessed the “automatic emergence of grounded language and communication … no human supervision!”

The implications of this kind of work are dizzying. Not only are researchers beginning to see how bots could communicate with one another, they may be scratching the surface of how syntax and compositional structure emerged among humans in the first place.

LaFrance’s article is well worth reading in its entirety especially since the speculation is focused on whether or not the chatbots’ creation is in fact language. There is no mention of consciousness and perhaps this is just a crazy idea but is it possible that these chatbots have consciousness? The question is particularly intriguing in light of some of philosopher David Chalmers’ work (see his 2014 TED talk in Vancouver, Canada: https://www.ted.com/talks/david_chalmers_how_do_you_explain_consciousness/transcript?language=en runs roughly 18 mins.); a text transcript is also featured. There’s a condensed version of Chalmers’ TED talk offered in a roughly 9 minute NPR (US National Public Radio) interview by Gus Raz. Here are some highlights from the text transcript,

So we’ve been hearing from brain scientists who are asking how a bunch of neurons and synaptic connections in the brain add up to us, to who we are. But it’s consciousness, the subjective experience of the mind, that allows us to ask the question in the first place. And where consciousness comes from – that is an entirely separate question.

DAVID CHALMERS: Well, I like to distinguish between the easy problems of consciousness and the hard problem.

RAZ: This is David Chalmers. He’s a philosopher who coined this term, the hard problem of consciousness.

CHALMERS: Well, the easy problems are ultimately a matter of explaining behavior – things we do. And I think brain science is great at problems like that. It can isolate a neural circuit and show how it enables you to see a red object, to respondent and say, that’s red. But the hard problem of consciousness is subjective experience. Why, when all that happens in this circuit, does it feel like something? How does a bunch of – 86 billion neurons interacting inside the brain, coming together – how does that produce the subjective experience of a mind and of the world?

RAZ: Here’s how David Chalmers begins his TED Talk.

(SOUNDBITE OF TED TALK)

CHALMERS: Right now, you have a movie playing inside your head. It has 3-D vision and surround sound for what you’re seeing and hearing right now. Your movie has smell and taste and touch. It has a sense of your body, pain, hunger, orgasms. It has emotions, anger and happiness. It has memories, like scenes from your childhood, playing before you. This movie is your stream of consciousness. If we weren’t conscious, nothing in our lives would have meaning or value. But at the same time, it’s the most mysterious phenomenon in the universe. Why are we conscious?

RAZ: Why is consciousness more than just the sum of the brain’s parts?

CHALMERS: Well, the question is, you know, what is the brain? It’s this giant complex computer, a bunch of interacting parts with great complexity. What does all that explain? That explains objective mechanism. Consciousness is subjective by its nature. It’s a matter of subjective experience. And it seems that we can imagine all of that stuff going on in the brain without consciousness. And the question is, where is the consciousness from there? It’s like, if someone could do that, they’d get a Nobel Prize, you know?

RAZ: Right.

CHALMERS: So here’s the mapping from this circuit to this state of consciousness. But underneath that is always going be the question, why and how does the brain give you consciousness in the first place?

(SOUNDBITE OF TED TALK)

CHALMERS: Right now, nobody knows the answers to those questions. So we may need one or two ideas that initially seem crazy before we can come to grips with consciousness, scientifically. The first crazy idea is that consciousness is fundamental. Physicists sometimes take some aspects of the universe as fundamental building blocks – space and time and mass – and you build up the world from there. Well, I think that’s the situation we’re in. If you can’t explain consciousness in terms of the existing fundamentals – space, time – the natural thing to do is to postulate consciousness itself as something fundamental – a fundamental building block of nature. The second crazy idea is that consciousness might be universal. This view is sometimes called panpsychism – pan, for all – psych, for mind. Every system is conscious. Not just humans, dogs, mice, flies, but even microbes. Even a photon has some degree of consciousness. The idea is not that photons are intelligent or thinking. You know, it’s not that a photon is wracked with angst because it’s thinking, oh, I’m always buzzing around near the speed of light. I never get to slow down and smell the roses. No, not like that. But the thought is, maybe photons might have some element of raw subjective feeling, some primitive precursor to consciousness.

RAZ: So this is a pretty big idea – right? – like, that not just flies, but microbes or photons all have consciousness. And I mean we, like, as humans, we want to believe that our consciousness is what makes us special, right – like, different from anything else.

CHALMERS: Well, I would say yes and no. I’d say the fact of consciousness does not make us special. But maybe we’ve a special type of consciousness ’cause you know, consciousness is not on and off. It comes in all these rich and amazing varieties. There’s vision. There’s hearing. There’s thinking. There’s emotion and so on. So our consciousness is far richer, I think, than the consciousness, say, of a mouse or a fly. But if you want to look for what makes us distinct, don’t look for just our being conscious, look for the kind of consciousness we have. …

Intriguing, non?

Vancouver premiere of Baba Brinkman’s Rap Guide to Consciousness

“Utterly unique… both brilliantly entertaining and hugely informative” ★ ★ ★ ★ ★ – Broadway Baby

“An education, inspiring, and wonderfully entertaining show from beginning to end” ★ ★ ★ ★ ★ – Mumble Comedy

There’s quite the poster for this rap guide performance,

In addition to  the Vancouver and Edinburgh performance (the show was premiered at the Brighton Fringe Festival in May 2017; see Simon Topping’s very brief review in this May 10, 2017 posting on the reviewshub.com), Brinkman is raising money (goal is $12,000US; he has raised a little over $3,000 with approximately one month before the deadline) to produce a CD. Here’s more from the Rap Guide to Consciousness campaign page on Indiegogo,

Brinkman has been working with neuroscientists, Dr. Anil Seth (professor and co-director of Sackler Centre for Consciousness Science) and Dr. Heather Berlin (Brinkman’s wife as noted earlier; see her Wikipedia entry or her website).

There’s a bit more information about the rap project and Anil Seth in a May 3, 2017 news item by James Hakner for the University of Sussex,

The research frontiers of consciousness science find an unusual outlet in an exciting new Rap Guide to Consciousness, premiering at this year’s Brighton Fringe Festival.

Professor Anil Seth, Co-Director of the Sackler Centre for Consciousness Science at the University of Sussex, has teamed up with New York-based ‘peer-reviewed rapper’ Baba Brinkman, to explore the latest findings from the neuroscience and cognitive psychology of subjective experience.

What is it like to be a baby? We might have to take LSD to find out. What is it like to be an octopus? Imagine most of your brain was actually built into your fingertips. What is it like to be a rapper kicking some of the world’s most complex lyrics for amused fringe audiences? Surreal.

In this new production, Baba brings his signature mix of rap comedy storytelling to the how and why behind your thoughts and perceptions. Mixing cutting-edge research with lyrical performance and projected visuals, Baba takes you through the twists and turns of the only organ it’s better to donate than receive: the human brain. Discover how the various subsystems of your brain come together to create your own rich experience of the world, including the sights and sounds of a scientifically peer-reviewed rapper dropping knowledge.

The result is a truly mind-blowing multimedia hip-hop theatre performance – the perfect meta-medium through which to communicate the dazzling science of consciousness.

Baba comments: “This topic is endlessly fascinating because it underlies everything we do pretty much all the time, which is probably why it remains one of the toughest ideas to get your head around. The first challenge with this show is just to get people to accept the (scientifically uncontroversial) idea that their brains and minds are actually the same thing viewed from different angles. But that’s just the starting point, after that the details get truly amazing.”

Baba Brinkman is a Canadian rap artist and award-winning playwright, best known for his “Rap Guide” series of plays and albums. Baba has toured the world and enjoyed successful runs at the Edinburgh Fringe Festival and off-Broadway in New York. The Rap Guide to Religion was nominated for a 2015 Drama Desk Award for “Unique Theatrical Experience” and The Rap Guide to Evolution (“Astonishing and brilliant” NY Times), won a Scotsman Fringe First Award and a Drama Desk Award nomination for “Outstanding Solo Performance”. The Rap Guide to Climate Chaos premiered in Edinburgh in 2015, followed by a six-month off-Broadway run in 2016.

Baba is also a pioneer in the genre of “lit-hop” or literary hip-hop, known for his adaptations of The Canterbury Tales, Beowulf, and Gilgamesh. He is a recent recipient of the National Center for Science Education’s “Friend of Darwin Award” for his efforts to improve the public understanding of evolutionary biology.

Anil Seth is an internationally renowned researcher into the biological basis of consciousness, with more than 100 (peer-reviewed!) academic journal papers on the subject. Alongside science he is equally committed to innovative public communication. A Wellcome Trust Engagement Fellow (from 2016) and the 2017 British Science Association President (Psychology), Professor Seth has co-conceived and consulted on many science-art projects including drama (Donmar Warehouse), dance (Siobhan Davies dance company), and the visual arts (with artist Lindsay Seers). He has also given popular public talks on consciousness at the Royal Institution (Friday Discourse) and at the main TED conference in Vancouver. He is a regular presence in print and on the radio and is the recipient of awards including the BBC Audio Award for Best Single Drama (for ‘The Sky is Wider’) and the Royal Society Young People’s Book Prize (for EyeBenders). This is his first venture into rap.

Professor Seth said: “There is nothing more familiar, and at the same time more mysterious than consciousness, but research is finally starting to shed light on this most central aspect of human existence. Modern neuroscience can be incredibly arcane and complex, posing challenges to us as public communicators.

“It’s been a real pleasure and privilege to work with Baba on this project over the last year. I never thought I’d get involved with a rap artist – but hearing Baba perform his ‘peer reviewed’ breakdowns of other scientific topics I realized here was an opportunity not to be missed.”

Interestingly, Seth has another Canadian connection; he’s a Senior Fellow of the Azrieli Program in Brain, Mind & Consciousness at the Canadian Institute for Advanced Research (CIFAR; Wikipedia entry). By the way, the institute  was promised $93.7M in the 2017 Canadian federal government budget for the establishment of a Pan-Canadian Artificial Intelligence Strategy (see my March 24, 2017 posting; scroll down about 25% of the way and look for the highlighted dollar amount). You can find out more about the Azrieli programme here and about CIFAR on its website.

The Hard Problem (a Tom Stoppard play)

Brinkman isn’t the only performance-based artist to be querying the concept of consciousness, Tom Stoppard has written a play about consciousness titled ‘The Hard Problem’, which debuted at the National Theatre (UK) in January 2015 (see BBC [British Broadcasting Corporation] news online’s Jan. 29, 2015 roundup of reviews). A May 25, 2017 commentary by Andrew Brown for the Guardian offers some insight into the play and the issues (Note: Links have been removed),

There is a lovely exchange in Tom Stoppard’s play about consciousness, The Hard Problem, when an atheist has been sneering at his girlfriend for praying. It is, he says, an utterly meaningless activity. Right, she says, then do one thing for me: pray! I can’t do that, he replies. It would betray all I believe in.

So prayer can have meanings, and enormously important ones, even for people who are certain that it doesn’t have the meaning it is meant to have. In that sense, your really convinced atheist is much more religious than someone who goes along with all the prayers just because that’s what everyone does, without for a moment supposing the action means anything more than asking about the weather.

The Hard Problem of the play’s title is a phrase coined by the Australian philosopher David Chalmers to describe the way in which consciousness arises from a physical world. What makes it hard is that we don’t understand it. What makes it a problem is slightly different. It isn’t the fact of consciousness, but our representations of consciousness, that give rise to most of the difficulties. We don’t know how to fit the first-person perspective into the third-person world that science describes and explores. But this isn’t because they don’t fit: it’s because we don’t understand how they fit. For some people, this becomes a question of consuming interest.

There are also a couple of video of Tom Stoppard, the playwright, discussing his play with various interested parties, the first being the director at the National Theatre who tackled the debut run, Nicolas Hytner: https://www.youtube.com/watch?v=s7J8rWu6HJg (it runs approximately 40 mins.). Then, there’s the chat Stoppard has with previously mentioned philosopher, David Chalmers: https://www.youtube.com/watch?v=4BPY2c_CiwA (this runs approximately 1 hr. 32 mins.).

I gather ‘consciousness’ is a hot topic these days and, in the venacular of the 1960s, I guess you could describe all of this as ‘expanding our consciousness’. Have a nice weekend!

Ishiguro’s robots and Swiss scientist question artificial intelligence at SXSW (South by Southwest) 2017

It seems unexpected to stumble across presentations on robots and on artificial intelligence at an entertainment conference such as South by South West (SXSW). Here’s why I thought so, from the SXSW Wikipedia entry (Note: Links have been removed),

South by Southwest (abbreviated as SXSW) is an annual conglomerate of film, interactive media, and music festivals and conferences that take place in mid-March in Austin, Texas, United States. It began in 1987, and has continued to grow in both scope and size every year. In 2011, the conference lasted for 10 days with SXSW Interactive lasting for 5 days, Music for 6 days, and Film running concurrently for 9 days.

Lifelike robots

The 2017 SXSW Interactive featured separate presentations by Japanese roboticist, Hiroshi Ishiguro (mentioned here a few times), and EPFL (École Polytechnique Fédérale de Lausanne; Switzerland) artificial intelligence expert, Marcel Salathé.

Ishiguro’s work is the subject of Harry McCracken’s March 14, 2017 article for Fast Company (Note: Links have been removed),

I’m sitting in the Japan Factory pavilion at SXSW in Austin, Texas, talking to two other attendees about whether human beings are more valuable than robots. I say that I believe human life to be uniquely precious, whereupon one of the others rebuts me by stating that humans allow cars to exist even though they kill humans.

It’s a reasonable point. But my fellow conventioneer has a bias: It’s a robot itself, with an ivory-colored, mask-like face and visible innards. So is the third participant in the conversation, a much more human automaton modeled on a Japanese woman and wearing a black-and-white blouse and a blue scarf.

We’re chatting as part of a demo of technologies developed by the robotics lab of Hiroshi Ishiguro, based at Osaka University, and Japanese telecommunications company NTT. Ishiguro has gained fame in the field by creating increasingly humanlike robots—that is, androids—with the ultimate goal of eliminating the uncanny valley that exists between people and robotic people.

I also caught up with Ishiguro himself at the conference—his second SXSW—to talk about his work. He’s a champion of the notion that people will respond best to robots who simulate humanity, thereby creating “a feeling of presence,” as he describes it. That gives him and his researchers a challenge that encompasses everything from technology to psychology. “Our approach is quite interdisciplinary,” he says, which is what prompted him to bring his work to SXSW.

Artificial intelligence (AI)

In a March 15, 2017 EPFL press release by Hilary Sanctuary, scientist Marcel Salathé poses the question: Is Reliable Artificial Intelligence Possible?,

In the quest for reliable artificial intelligence, EPFL scientist Marcel Salathé argues that AI technology should be openly available. He will be discussing the topic at this year’s edition of South by South West on March 14th in Austin, Texas.

Will artificial intelligence (AI) change the nature of work? For EPFL theoretical biologist Marcel Salathé, the answer is invariably yes. To him, a more fundamental question that needs to be addressed is who owns that artificial intelligence?

“We have to hold AI accountable, and the only way to do this is to verify it for biases and make sure there is no deliberate misinformation,” says Salathé. “This is not possible if the AI is privatized.”

AI is both the algorithm and the data

So what exactly is AI? It is generally regarded as “intelligence exhibited by machines”. Today, it is highly task specific, specially designed to beat humans at strategic games like Chess and Go, or diagnose skin disease on par with doctors’ skills.

On a practical level, AI is implemented through what scientists call “machine learning”, which means using a computer to run specifically designed software that can be “trained”, i.e. process data with the help of algorithms and to correctly identify certain features from that data set. Like human cognition, AI learns by trial and error. Unlike humans, however, AI can process and recall large quantities of data, giving it a tremendous advantage over us.

Crucial to AI learning, therefore, is the underlying data. For Salathé, AI is defined by both the algorithm and the data, and as such, both should be publicly available.

Deep learning algorithms can be perturbed

Last year, Salathé created an algorithm to recognize plant diseases. With more than 50,000 photos of healthy and diseased plants in the database, the algorithm uses artificial intelligence to diagnose plant diseases with the help of your smartphone. As for human disease, a recent study by a Stanford Group on cancer showed that AI can be trained to recognize skin cancer slightly better than a group of doctors. The consequences are far-reaching: AI may one day diagnose our diseases instead of doctors. If so, will we really be able to trust its diagnosis?

These diagnostic tools use data sets of images to train and learn. But visual data sets can be perturbed that prevent deep learning algorithms from correctly classifying images. Deep neural networks are highly vulnerable to visual perturbations that are practically impossible to detect with the naked eye, yet causing the AI to misclassify images.

In future implementations of AI-assisted medical diagnostic tools, these perturbations pose a serious threat. More generally, the perturbations are real and may already be affecting the filtered information that reaches us every day. These vulnerabilities underscore the importance of certifying AI technology and monitoring its reliability.

As I noted earlier, these are not the kind of presentations you’d expect at an ‘entertainment’ festival.

Revisiting the scientific past for new breakthroughs

A March 2, 2017 article on phys.org features a thought-provoking (and, for some of us, confirming) take on scientific progress  (Note: Links have been removed),

The idea that science isn’t a process of constant progress might make some modern scientists feel a bit twitchy. Surely we know more now than we did 100 years ago? We’ve sequenced the genome, explored space and considerably lengthened the average human lifespan. We’ve invented aircraft, computers and nuclear energy. We’ve developed theories of relativity and quantum mechanics to explain how the universe works.

However, treating the history of science as a linear story of progression doesn’t reflect wholly how ideas emerge and are adapted, forgotten, rediscovered or ignored. While we are happy with the notion that the arts can return to old ideas, for example in neoclassicism, this idea is not commonly recognised in science. Is this constraint really present in principle? Or is it more a comment on received practice or, worse, on the general ignorance of the scientific community of its own intellectual history?

For one thing, not all lines of scientific enquiry are pursued to conclusion. For example, a few years ago, historian of science Hasok Chang undertook a careful examination of notebooks from scientists working in the 19th century. He unearthed notes from experiments in electrochemistry whose results received no explanation at the time. After repeating the experiments himself, Chang showed the results still don’t have a full explanation today. These research programmes had not been completed, simply put to one side and forgotten.

A March 1, 2017 essay by Giles Gasper (Durham University), Hannah Smithson (University of Oxford) and Tom Mcleish (Durham University) for The Conversation, which originated the article, expands on the theme (Note: Links have been removed),

… looping back into forgotten scientific history might also provide an alternative, regenerative way of thinking that doesn’t rely on what has come immediately before it.

Collaborating with an international team of colleagues, we have taken this hypothesis further by bringing scientists into close contact with scientific treatises from the early 13th century. The treatises were composed by the English polymath Robert Grosseteste – who later became Bishop of Lincoln – between 1195 and 1230. They cover a wide range of topics we would recognise as key to modern physics, including sound, light, colour, comets, the planets, the origin of the cosmos and more.

We have worked with paleographers (handwriting experts) and Latinists to decipher Grosseteste’s manuscripts, and with philosophers, theologians, historians and scientists to provide intellectual interpretation and context to his work. As a result, we’ve discovered that scientific and mathematical minds today still resonate with Grosseteste’s deeply physical and structured thinking.

Our first intuition and hope was that the scientists might bring a new analytic perspective to these very technical texts. And so it proved: the deep mathematical structure of a small treatise on colour, the De colore, was shown to describe what we would now call a three-dimensional abstract co-ordinate space for colour.

But more was true. During the examination of each treatise, at some point one of the group would say: “Did anyone ever try doing …?” or “What would happen if we followed through with this calculation, supposing he meant …”. Responding to this thinker from eight centuries ago has, to our delight and surprise, inspired new scientific work of a rather fresh cut. It isn’t connected in a linear way to current research programmes, but sheds light on them from new directions.

I encourage you to read the essay in its entirety.

Science as a post-truth concept

The word of 2016, according to the Oxford Dictionary of English, is ‘post-truth’ and Steve Fuller, a professor from the University of Warwick (UK), has written an intriguing Dec. 15, 2016 essay  for the Guardian tracing the origins of post-truth as it relates to the sciences (Note: Links have been removed),

Even today, more than fifty years after its first edition, Thomas Kuhn’s The Structure of Scientific Revolutions remains the first port of call to learn about the history, philosophy or sociology of science. This is the book famous for talking about science as governed by ‘paradigms’ until overtaken by ‘revolutions’.

Kuhn argued that the way that both scientists and the general public need to understand the history of science is Orwellian. He is alluding to 1984, in which the protagonist’s job is to rewrite newspapers from the past to make it seem as though the government’s current policy is where it had been heading all along. In this perpetually airbrushed version of history, the public never sees the U-turns, switches of allegiance and errors of judgement that might cause them to question the state’s progressive narrative. Confidence in the status quo is maintained and new recruits are inspired to follow in its lead. Kuhn claimed that what applies to totalitarian 1984 also applies to science united under the spell of a paradigm.
ADVERTISING

What makes Kuhn’s account of science ‘post-truth’ is that truth is no longer the arbiter of legitimate power but rather the mask of legitimacy that is worn by everyone in pursuit of power. Truth is just one more – albeit perhaps the most important – resource in a power game without end. In this respect, science differs from politics only in that the masks of its players rarely drop.

The explanation for what happens behind the masks lies in the work of the Italian political economist Vilfredo Pareto (1848-1923), devotee of Machiavelli, admired by Mussolini and one of sociology’s forgotten founders. Kuhn spent his formative years at Harvard in the late 1930s when the local kingmaker, biochemist Lawrence Henderson, not only taught the first history of science courses but also convened an interdisciplinary ‘Pareto Circle’ to get the university’s rising stars acquainted with the person he regarded as Marx’s only true rival.

For Pareto, what passes for social order is the result of the interplay of two sorts of elites, which he called, following Machiavelli, ‘lions’ and ‘foxes’. The lions acquire legitimacy from tradition, which in science is based on expertise rather than lineage or custom. Yet, like these earlier forms of legitimacy, expertise derives its authority from the cumulative weight of intergenerational experience. This is exactly what Kuhn meant by a ‘paradigm’ in science – a set of conventions by which knowledge builds in an orderly fashion to complete a certain world-view established by a founding figure – say, Newton or Darwin. Each new piece of knowledge is anointed by a process of ‘peer review’.

As in 1984, the lions normally dictate the historical narrative. But on the cutting room floor lies the activities of the other set of elites, the foxes. In today’s politics of science, they are known by a variety of names, ranging from ‘mavericks’ to ‘social constructivists’ to ‘pseudoscientists’. Foxes are characterised by dissent and unrest, thriving in a world of openness and opportunity.

Foxes stress the present as an ecstatic moment in which there is everything to play for. This includes a decisive break with ‘the past’, which they know has been fictionalized anyway, as in 1984. Self-styled visionaries present themselves, like Galileo, as the first to see what is in plain sight. Expertise appears as a repository of corrupt judgement designed to suppress promising alternatives to already bankrupt positions. For Kuhn, the scientific foxes get the upper hand whenever cracks appear in the lions’ smooth narrative, the persistent ‘anomalies’ that can’t be explained by the ruling paradigm.

But the foxes have their own Achilles Heel: They are strong in opposition but divisively self-critical in office. …

I encourage you to read the essay in its entirety although I don’t necessarily subscribe to the some of the statements. For example, I wouldn’t lump ‘mavericks’, ‘social constructivists’, and ‘pseudoscientists’ together without some discussion about ‘pseudoscience’. It’s true that an accusation of ‘pseudoscience’ is often leveled at people who are challenging the status quo but there are also situations where people use science as a mask to legitimate some fairly hinky work.

Westworld: a US television programme investigating AI (artificial intelligence) and consciousness

The US television network, Home Box Office (HBO) is getting ready to première Westworld, a new series based on a movie first released in 1973. Here’s more about the movie from its Wikipedia entry (Note: Links have been removed),

Westworld is a 1973 science fiction Western thriller film written and directed by novelist Michael Crichton and produced by Paul Lazarus III about amusement park robots that malfunction and begin killing visitors. It stars Yul Brynner as an android in a futuristic Western-themed amusement park, and Richard Benjamin and James Brolin as guests of the park.

Westworld was the first theatrical feature directed by Michael Crichton.[3] It was also the first feature film to use digital image processing, to pixellate photography to simulate an android point of view.[4] The film was nominated for Hugo, Nebula and Saturn awards, and was followed by a sequel film, Futureworld, and a short-lived television series, Beyond Westworld. In August 2013, HBO announced plans for a television series based on the original film.

The latest version is due to start broadcasting in the US on Sunday, Oct. 2, 2016 and as part of the publicity effort the producers are profiled by Sean Captain for Fast Company in a Sept. 30, 2016 article,

As Game of Thrones marches into its final seasons, HBO is debuting this Sunday what it hopes—and is betting millions of dollars on—will be its new blockbuster series: Westworld, a thorough reimagining of Michael Crichton’s 1973 cult classic film about a Western theme park populated by lifelike robot hosts. A philosophical prelude to Jurassic Park, Crichton’s Westworld is a cautionary tale about technology gone very wrong: the classic tale of robots that rise up and kill the humans. HBO’s new series, starring Evan Rachel Wood, Anthony Hopkins, and Ed Harris, is subtler and also darker: The humans are the scary ones.

“We subverted the entire premise of Westworld in that our sympathies are meant to be with the robots, the hosts,” says series co-creator Lisa Joy. She’s sitting on a couch in her Burbank office next to her partner in life and on the show—writer, director, producer, and husband Jonathan Nolan—who goes by Jonah. …

Their Westworld, which runs in the revered Sunday-night 9 p.m. time slot, combines present-day production values and futuristic technological visions—thoroughly revamping Crichton’s story with hybrid mechanical-biological robots [emphasis mine] fumbling along the blurry line between simulated and actual consciousness.

Captain never does explain the “hybrid mechanical-biological robots.” For example, do they have human skin or other organs grown for use in a robot? In other words, how are they hybrid?

That nitpick aside, the article provides some interesting nuggets of information and insight into the themes and ideas 2016 Westworld’s creators are exploring (Note: A link has been removed),

… Based on the four episodes I previewed (which get progressively more interesting), Westworld does a good job with the trope—which focused especially on the awakening of Dolores, an old soul of a robot played by Evan Rachel Wood. Dolores is also the catchall Spanish word for suffering, pain, grief, and other displeasures. “There are no coincidences in Westworld,” says Joy, noting that the name is also a play on Dolly, the first cloned mammal.

The show operates on a deeper, though hard-to-define level, that runs beneath the shoot-em and screw-em frontier adventure and robotic enlightenment narratives. It’s an allegory of how even today’s artificial intelligence is already taking over, by cataloging and monetizing our lives and identities. “Google and Facebook, their business is reading your mind in order to advertise shit to you,” says Jonah Nolan. …

“Exist free of rules, laws or judgment. No impulse is taboo,” reads a spoof home page for the resort that HBO launched a few weeks ago. That’s lived to the fullest by the park’s utterly sadistic loyal guest, played by Ed Harris and known only as the Man in Black.

The article also features some quotes from scientists on the topic of artificial intelligence (Note: Links have been removed),

“In some sense, being human, but less than human, it’s a good thing,” says Jon Gratch, professor of computer science and psychology at the University of Southern California [USC]. Gratch directs research at the university’s Institute for Creative Technologies on “virtual humans,” AI-driven onscreen avatars used in military-funded training programs. One of the projects, SimSensei, features an avatar of a sympathetic female therapist, Ellie. It uses AI and sensors to interpret facial expressions, posture, tension in the voice, and word choices by users in order to direct a conversation with them.

“One of the things that we’ve found is that people don’t feel like they’re being judged by this character,” says Gratch. In work with a National Guard unit, Ellie elicited more honest responses about their psychological stresses than a web form did, he says. Other data show that people are more honest when they know the avatar is controlled by an AI versus being told that it was controlled remotely by a human mental health clinician.

“If you build it like a human, and it can interact like a human. That solves a lot of the human-computer or human-robot interaction issues,” says professor Paul Rosenbloom, also with USC’s Institute for Creative Technologies. He works on artificial general intelligence, or AGI—the effort to create a human-like or human level of intellect.

Rosenbloom is building an AGI platform called Sigma that models human cognition, including emotions. These could make a more effective robotic tutor, for instance, “There are times you want the person to know you are unhappy with them, times you want them to know that you think they’re doing great,” he says, where “you” is the AI programmer. “And there’s an emotional component as well as the content.”

Achieving full AGI could take a long time, says Rosenbloom, perhaps a century. Bernie Meyerson, IBM’s chief innovation officer, is also circumspect in predicting if or when Watson could evolve into something like HAL or Her. “Boy, we are so far from that reality, or even that possibility, that it becomes ludicrous trying to get hung up there, when we’re trying to get something to reasonably deal with fact-based data,” he says.

Gratch, Rosenbloom, and Meyerson are talking about screen-based entities and concepts of consciousness and emotions. Then, there’s a scientist who’s talking about the difficulties with robots,

… Ken Goldberg, an artist and professor of engineering at UC [University of California] Berkeley, calls the notion of cyborg robots in Westworld “a pretty common trope in science fiction.” (Joy will take up the theme again, as the screenwriter for a new Battlestar Galactica movie.) Goldberg’s lab is struggling just to build and program a robotic hand that can reliably pick things up. But a sympathetic, somewhat believable Dolores in a virtual setting is not so farfetched.

Captain delves further into a thorny issue,

“Can simulations, at some point, become the real thing?” asks Patrick Lin, director of the Ethics + Emerging Sciences Group at California Polytechnic State University. “If we perfectly simulate a rainstorm on a computer, it’s still not a rainstorm. We won’t get wet. But is the mind or consciousness different? The jury is still out.”

While artificial consciousness is still in the dreamy phase, today’s level of AI is serious business. “What was sort of a highfalutin philosophical question a few years ago has become an urgent industrial need,” says Jonah Nolan. It’s not clear yet how the Delos management intends, beyond entrance fees, to monetize Westworld, although you get a hint when Ford tells Theresa Cullen “We know everything about our guests, don’t we? As we know everything about our employees.”

AI has a clear moneymaking model in this world, according to Nolan. “Facebook is monetizing your social graph, and Google is advertising to you.” Both companies (and others) are investing in AI to better understand users and find ways to make money off this knowledge. …

As my colleague David Bruggeman has often noted on his Pasco Phronesis blog, there’s a lot of science on television.

For anyone who’s interested in artificial intelligence and the effects it may have on urban life, see my Sept. 27, 2016 posting featuring the ‘One Hundred Year Study on Artificial Intelligence (AI100)’, hosted by Stanford University.

Points to anyone who recognized Jonah (Jonathan) Nolan as the producer for the US television series, Person of Interest, a programme based on the concept of a supercomputer with intelligence and personality and the ability to continuously monitor the population 24/7.

“Science is too important to be left to scientists alone”

The quote (“Science is too important to be left to scientists alone”) is from an essay/speech in the UK’s Guardian newspaper in their political science section. Written by Imran Khan, chief executive of the British Science Association, it marks the association’s relaunch (from a Guardian Dec. 1, 2015 piece),

No-one should feel the need to apologise for not being a scientist. And yet when I tell people I work for the British Science Association (BSA), embarrassment is a common response. “I don’t really understand science”, I hear. “Oh, I’m more of an arty person”, they say, or, “the last time I did science was at school”.

Such embarrassment is misplaced; not liking science is fine. The real concern is when people are excluded when they don’t need to be – and this happens with science more than it does for many other parts of our culture. Music, literature, politics, and sport, for instance, can all be shaped by anyone who consumes, creates, or critiques them – not just by their respective professional classes.

… Science is too important, valuable and fascinating to be left to professional scientists alone. For the good of society, the public, and scientific progress itself, science needs a broader community.

The scientific method can explain the world around us in an elegant and creative way, but scientists cannot escape the influence of external pressures and personal bias. Scientists have been put on a pedestal and are often seen as entirely rational, objective and expert – but this paints science as a near-infallible institution that doesn’t want or require engagement from non-scientists.

That is asking for trouble.

Given how strongly I agree with Khan’s comments, I’m not sure I can give his essay my usual critical eye on his writing. Here’s more,

As Richard Horton, editor of the Lancet, argues, a reduction in trust can be beneficial for those involved. In medicine, decades of activism and the prevalence of health information online is forcing greater transparency and improvements in medical practice. Can this approach be extended to the rest of science? Could we have a citizenship that critically questions all of the UK’s public institutions, including science?

Khan goes on to make some suggestions for more thoughtful science involvement,

For more people to be involved in science, we have to create a shared understanding of what science is. For instance, it’s tempting to see science as fundamentally progressive, an inherently benevolent force. But we have to recognise that it can have a dark side as well. This isn’t just an issue for scientists; the BSA believes that society as a whole should be able to bear some responsibility for how science is used.

Last year, for instance, we marked the centenary of the start of the First World War. It was one of the earliest – but certainly not the last – conflicts where the products of science were used to gas other human beings in their hundreds of thousands. Mustard gas, chlorine and phosgene were developed and deployed by both sides, despite previous treaties having banned them.

Nearly 200,000 British troops alone were struck by chemical attacks; non-fatal doses often scarred or afflicted soldiers for life. For many, this was the moment when we really became aware of the indiscriminately destructive potential of science. But, as part of the same conflict, science was also used to develop innovations such as blood transfusion, prosthetic limbs and reconstructive surgery.

Science does not exist in a moral vacuum. It is not inherently good or evil, but a platform for expressing human instincts, whether they be violence, kindness or creativity. We should celebrate new discoveries such as the Higgs Boson and the Mars Rover but we also need to find a space where scientists and the public can be involved in a debate about responsible scientific innovation. Both the innovators and the rest of us need to be held to account.

It is vital that the processes and products of science are readily available for the public to understand and interrogate. This is not to say that science isn’t regulated. One of the distinctive strengths of science is peer review; the process by which scientists hold each other to account. [emphasis mine]

Theoretically, peer review is the process by which scientists are held accountable by other scientists. However, it is an imperfect process as you can see in my Nov. 26, 2015 posting (A view to controversies about nanoparticle drug delivery, sticky-flares, and a PNAS surprise) which outlines one very current example of the difficulty two scientists have encountered when questioning results from a very prominent scientist in the field of nanomedicine. (There’s a formal peer review process which takes place prior to publication but informally scientists also respond to published  research with letters to the journal editors critiquing the work.)

Getting back to Khan, he provides an example of a broad-based group with authority over experts in medicine and science (Note: A link has been removed),

As an example, when the Human Fertilisation & Embryology Authority was created in 1991, its rules stipulated that the Chair, Deputy Chair and at least half of HFEA members needed to come from outside medicine or science. The group currently includes several people who have undergone IVF – people who are directly affected by the technology that the authority regulates.

This is a strong first step towards making funding and regulatory bodies truly representative of the population. While it has been good to see more diversity, we need to take this further. Key decisions on scientific innovation should always involve public dialogue, and it should be the responsibility of such boards to ensure that this happens.

For my last excerpt, Khan discusses education (Note: A link has been removed),

A scientific profession that looked more like the rest of the UK, and where a greater diversity of people knew scientists personally, should be something that we all aim for.

But, for the benefit of those who don’t rub shoulders with scientists, we also need to challenge the assumption that the study of science is primarily for the training of future experts. Although a report by the Royal Academy of Engineering states that one million engineers are needed by 2020 to meet the UK’s demands, we can’t let such figures instrumentalise education. The core aim of science education should be to ensure students leave school with the skills and confidence to discuss and shape scientific and technological advances in society, whatever their career choices.

One way to do this would be to stop segregating science into disciplines at school. In an age of inter-disciplinarity, studying physics, biology, and chemistry as supposedly separate subjects could be seen as an anachronism even for those going on to become scientists. But it’s perhaps even less helpful for those who we simply want to be members of a scientifically literate society; might a better route be having young people look at the science of, say, climate change, alongside its historical, geographic, and political elements?

(For a somewhat related piece, see my Aug. 7, 2015 posting titled: Science snobbery and the problem of accessibility.)

A provocative set of ideas, I encourage you to read Khan’s piece where he takes his ideas much further than I did mine. Khan’s thoughts can be found in their entirety in his Dec. 1, 2015 piece for the Guardian.

A divisive scientific/philosophical debate that changed everything: Einstein vs. Bergson on the nature of time

A feud between a scientist and a philosopher—this seems like the setup for a joke but it’s not. According to a May 26, 2015 news item on phys.org, the book ‘The Physicist and the Philosopher: Einstein, Bergson, and the Debate That Changed Our Understanding of Time‘ chronicles a seminal debate and conflict that reverberates to this day,

Two of the 20th century’s greatest minds, one of them physicist Albert Einstein, came to intellectual blows one day in Paris in 1922. Their dispute, before a learned audience, was about the nature of time – mostly in connection with Einstein’s most famous work, the theory of relativity, which marks its centennial this year.

One immediate result of the controversy: There would be no mention of relativity in Einstein’s Nobel Prize, awarded a few months later.

One long-term result: a split between science and the humanities that continues to this day.

A May 26, 2015 University of Illinois at Urbana-Champaign news release, which originated the news item, provides some insight into a fascinating story,

The philosopher in the title, and Einstein’s adversary that day, was Henri Bergson, a French philosopher who was much more famous at the time than the German-born Einstein. Presidents and prime ministers carefully read Bergson’s work, and his public lectures often were filled to capacity. He was perhaps the pre-eminent public intellectual of his time, Canales [said.

Bergson did not challenge Einstein’s scientific claims about relativity, including the then-startling claim of time dilation, in which time slows down for objects traveling at higher speeds, Canales said.

What he challenged instead was Einstein’s interpretation of those claims, saying it went beyond science and was “a metaphysics grafted upon science.” He said that Einstein’s theory did not consider time as it was lived in human experience, the aspects of time that could not be captured by clocks or formulas.

Einstein quickly dismissed the philosopher’s criticism. To an audience that day of mostly philosophers, he made the incendiary statement that “the time of the philosophers does not exist.”

In the aftermath, Bergson published a book in which he thoroughly laid out his criticism of Einstein’s relativity and his theory of time. Both men and their supporters also spread their views through publications and letters, some of which employed “highly effective backbiting,” Canales said.

Bergson and Einstein also seemed to be on opposite ends of almost every pertinent issue of the time, from war and peace to race and faith, she said. “They seemed to take opposite stances in everything.”

Einstein supporters claimed that Bergson, though a gifted mathematician, did not completely understand Einstein’s theory. Bergson thought his theory of time was misunderstood by Einstein.

Bergson’s influence has been most prominent in novels and film, in their use of narrative twists and breaks and in time-shifting between past and future, Canales said. He also has had support among scientists, among them leading physicists who had helped develop relativity, as well as experts on quantum mechanics.

It was Einstein’s ideas that gained prominence, however, in part because later research only reinforced the science of relativity, but also because Bergson was effectively discredited by scientists, Canales said. Outside of philosophy, Bergson has been largely forgotten and is rarely even mentioned in Einstein biographies.

Canales said her book tells a “backstory of the rise of science” in the 20th century. It’s a story of “misunderstanding and mistrust,” she said.

“I took a pessimistic view of human nature and of our capacity to understand each other, and I think that view actually illuminates why so many humanists cannot talk to scientists, and scientists cannot talk to humanists.”

Canales said she sought to give an even-handed treatment to the two men and their views. In the process, however, she also sought to rehabilitate Bergson.

Just as Bergson was painted by some as anti-science, Canales said she knows she takes a similar risk in trying to give him his due in the dispute with Einstein, though it is not her intent. Being against science in the modern world, “makes no sense,” she said. “Clearly we should be for science.”

But we also need to think about science critically, Canales said. “We’re not taught to see science as it really is, as it really is practiced, as it really is done.” She said she hopes her book might help scientists and others understand the place of science “in more realistic terms.”

Canales’ book was published by Princeton University Press May 26, 2015. ‘The Physicist and the Philosopher: Einstein, Bergson, and the Debate That Changed Our Understanding of Time’ can be purchased here.

I expect anyone who reads this blog is likely to be familiar with Einstein but perhaps less so with Bergson. Here’s more about Bergson from his Wikipedia entry (Note: Links have been removed),

Henri-Louis Bergson (French: [bɛʁksɔn]; 18 October 1859 – 4 January 1941) was a major French philosopher, influential especially in the first half of the 20th century. Bergson convinced many thinkers that the processes of immediate experience and intuition are more significant than abstract rationalism and science for understanding reality. Bergson had a long affair with musicologist Janet Levy which led to her article “A Source of Musical Wit and Humor.” This was a well-regarded article used by many later writers.

He was awarded the 1927 Nobel Prize in Literature “in recognition of his rich and vitalizing ideas and the brilliant skill with which they have been presented”.[2] In 1930 France awarded him its highest honour, the Grand-Croix de la Legion d’honneur.

Brains, guts, health, and consciouness at TED 2014′s Session 5: Us

While most of the speakers I’m mentioning are the ‘science’ speakers in this session, they are more precisely ‘medical science’ speakers which takes me further than usual out of my comfort zone. That said, Nancy Kanwisher, brain researcher, opened the session (from her TED biography),

Using cutting-edge fMRI technology as her lens, Nancy Kanwisher zooms in on the brain regions responsible for some surprisingly specific elements of cognition.

Does the brain use specialized processors to solve complex problems, or does it rely instead on more general-purpose systems?

This question has been at the crux of brain research for centuries. MIT [Massachusetts Institute of Technology] researcher Nancy Kanwisher seeks to answer this question by discovering a “parts list” for the human mind and brain. “Understanding the nature of the human mind,” she says, “is arguably the greatest intellectual quest of all time.”

As many of us now know courtesy of researchers like Kanwisher, the brain has both general purpose regions and specialized regions for perception and complex processing but Kanwisher’s presentation was as much about the process of discovery as it was about the discoveries she and her colleagues have made. She talked about her personal experiences with functional magnetic resonance imaging (fMRI) as she tested (many times) her own brain first and then spent years looking at grayscale images as she decoded what she was observing and tested over and over and over again.

Next came the ‘gut guy’, or as microbial ecologist Rob Knight’s TED biography describes him,

Rob Knight explores the unseen microbial world that exists literally right under our noses — and everywhere else on (and in) our bodies.

Using scatological research methods that might repel the squeamish, microbial researcher Rob Knight uncovers the secret ecosystem (or “microbiome”) of microbes that inhabit our bodies — and the bodies of every creature on earth. In the process, he’s discovered a complex internal ecology that affects everything from weight loss to our susceptibility to disease. As he said to Nature in 2012, “What motivates me, from a pragmatic standpoint, is how understanding the microbial world might help us improve human and environmental health.”

Knight made the case that our microbes are what give us our individuality by noting that 99.99% of our DNA is the same from one person to the next but out microbial communities vary greatly person to person and the community in your mouth varies greatly from the community on your skin. He and his colleagues are using the information to consider new types of medical interventions. For example, research has shown that giving children antibiotics before the age of six months affects their future health.

Interestingly, we carry about 3 lbs. of microbes individually and Knight and his colleagues are still gathering information about those lbs. He mentioned the American Gut project (and solicited future volunteers from the live audience by mentioning he had just happened to bring 100 kits which were available at his table outside). This project is for US participant only.

Stephen Friend, oncologist and open science advocate was featured next. From his TED biography,

Inspired by open-source software models, Sage Bionetworks co-founder Stephen Friend builds tools that facilitate research sharing on a massive and revolutionary scale.

While working for Merck, Stephen Friend became frustrated by the slow pace at which big pharma created new treatments for desperate patients. Studying shared models like Wikipedia, Friend realized that the complexities of disease could only be understood — and combated — with collaboration and transparency, not by isolated scientists working in secret with proprietary data

Friend has a great name for someone who advocates for transparency and openness. He opened with stories about his work and how he came to be inspired to look for health rather than disease. He noted that for the most part, medical research is focused on the question of what went wrong with a patient rather than asking if healthy people have some sort of natural immunity or protection from cancer, Alzheimer’s, etc. Perhaps by examining health people we can find ways to more effectively intervene.

He provided two examples of research that examined natural immunity such as research in San Francisco (California) into why a small but significant percentage of people with HIV never developed AIDS; his other example was regarding research into lipid levels and why some people with high levels never develop heart disease.

I’m a little foggy about this point but I think he made a request for information about these medical phenomena and people from around the world shared their research with him in an open and transparent fashion.

This next bit was clear to me, he and his colleagues are moving to another stage with their research initiative which they have named the Resilience Project; Unexpected Heroes. He too solicited volunteers from the audience. I haven’t been able to locate a website for the project but there maybe some on the Sage Bionetworks website, the organization Friend co-founded. Good luck!

Finally, I wasn’t expecting to write about David Chalmers so my notes aren’t very good. A philosopher, here’s an excerpt from Chalmers’ TED biography,

In his work, David Chalmers explores the “hard problem of consciousness” — the idea that science can’t ever explain our subjective experience.

David Chalmers is a philosopher at the Australian National University and New York University. He works in philosophy of mind and in related areas of philosophy and cognitive science. While he’s especially known for his theories on consciousness, he’s also interested (and has extensively published) in all sorts of other issues in the foundations of cognitive science, the philosophy of language, metaphysics and epistemology.

Chalmers provided an interesting bookend to a session started with a brain researcher (Nancy Kanwisher) who breaks the brain down into various processing regions (vastly oversimplified but the easiest way to summarize her work in this context). Chalmers reviewed the ‘science of consciousness’ and noted that current work in science tends to be reductionist, i.e., examining parts of things such as brains and that same reductionism has been brought to the question of consciousness.

Rather than trying to prove consciousness, Chalmers proposes that we consider it a fundamental in the same way that we consider time, space, and mass to be fundamental. He noted that there’s precedence for additions and gave the example of James Clerk Maxwell and his proposal to consider electricity and magnetism as fundamental.

Chalmers next suggestion is a little more outré and based on some thinking (sorry I didn’t catch the theorist’s name) that suggests everything, including photons, has a type of consciousness (but not intelligence).
