The Role of Light in Philosophy (2008)

From The Philosopher, Volume LXXXXVI No.1

By Manoj Thulasidas

Reality, as we sense it, is not quite real. The stars we see in the night sky, for instance, are not really there. They may have moved or even died by the time we get to see them. This unreality is due to the time it takes for light from the distant stars and galaxies to reach us. We know of this delay.

Even the sun that we know so well is already eight minutes old by the time we see it. This fact does not seem to present particularly grave epistemological problems - if we want to know what is going on at the sun now, all we have to do is to wait for eight minutes. We only have to 'correct' for the distortions in our perception due to the finite speed of light before we can trust what we see. The same phenomenon in seeing has a lesser-known manifestation in the way we perceive moving objects. Some heavenly bodies appear as though they are moving several times the speed of light, whereas their 'real' speed must be a lot less than that.

What is surprising (and seldom highlighted) is that when it comes to sensing motion, we cannot back-calculate in the same kind of way as we can to correct for the delay in observation of the sun. If we see a celestial body moving at an improbably high speed, we cannot calculate how fast or even in what direction it is 'really' moving without first having to make certain further assumptions.

Einstein chose to resolve the problem by treating perception as distorted and inventing new fundamental properties in the arena of physics - in the description of space and time. One core idea of the Special Theory of Relativity is that the human notion of an orderly sequence of events in time needs to be abandoned. In fact, since it takes time for light from an event at a distant place to reach us, and for us to become aware of it, the concept of 'now' no longer makes any sense, for example, when we speak of a sunspot appearing on the surface of the sun just at the moment that the astronomer was trying to photograph it. Simultaneity is relative.

Einstein instead redefined simultaneity by using the instants in time we detect the event. Detection, as he defined it, involves a round-trip travel of light similar to radar detection. We send out a signal travelling at the speed of light, and wait for the reflection. If the reflected pulse from two events reaches us at the same instant, then they are simultaneous. But another way of looking at it is simply to call two events 'simultaneous' if the light from them reaches us at the same instant. In other words, we can use the light generated by the objects under observation rather than sending signals to them and looking at the reflection.

This difference may sound like a hair-splitting technicality, but it does make an enormous difference to the predictions we can make. Einstein's choice results in a mathematical picture that has many desirable properties, including that of making further theoretical development more elegant. But then, Einstein believed, as a matter of faith it would seem, that the rules governing the universe must be 'elegant.' However, the other approach has an advantage when it comes to describing objects in motion. Because, of course, we don't use radar to see the stars in motion; we merely sense the light (or other radiation) coming from them. Yet using this kind of sensory paradigm, rather than 'radar-like detection,' to describe the universe results in an uglier mathematical picture. Einstein would not approve!

The mathematical difference spawns different philosophical stances, which in turn percolate to the understanding of our physical picture of reality. As an illustration, suppose we observe, through a radio telescope, two objects in the sky, with roughly the same shape, size and properties. The only thing we know for sure is that the radio waves from these two different points in the sky reach us at the same instant in time. We can only guess when the waves started their journeys.

If we assume (as we routinely do) that the waves started the journey roughly at the same instant in time, we end up with a picture of two 'real' symmetric lobes more or less the way see them. But there is another, different possibility and that is that the waves originated from the same object (which is in motion) at two different instants in time, reaching the telescope at the same instant. This possibility would additionally explain some spectral and temporal properties of such symmetric radio sources. So which of these two pictures should we take as real? Two symmetric objects as we see them or one object moving in such a way as to give us that impression? Does it really matter which one is 'real'? Does 'real' mean anything in this context?

Special Relativity gives an unambiguous answer to this question. The mathematics rules out the possibility of a single object moving in such a fashion as to mimic two objects. Essentially, what we see is what is out there. Yet, if we define events by what we perceive, the only philosophical stance that makes sense is the one that disconnects the sensed reality from the causes lying behind what is being sensed.

This disconnect is not uncommon in philosophical schools of thought. Phenomenalism, for instance, holds the view that space and time are not objective realities. They are merely the medium of our perception. All the phenomena that happen in space and time are merely bundles of our perception. In other words, space and time are cognitive constructs arising from perception. Thus, all the physical properties that we ascribe to space and time can only apply to the phenomenal reality (the reality of 'things-in-the-world' as we sense it. The underlying reality (which holds the physical causes of our perception), by contrast, remains beyond our cognitive reach.

Yet there is a chasm between the views of philosophy and modern physics. Not for nothing did the Nobel Prize winning physicist, Steven Weinberg, wonder, in his book Dreams of a Final Theory, why the contribution from philosophy to physics had been so surprisingly small. Perhaps it is because physics has yet to come to terms with the fact that when it comes to seeing the universe, there is no such thing as an optical illusion - which is probably what Goethe meant when he said, 'Optical illusion is optical truth.' The distinction (or lack thereof) between optical illusion and truth is one of the oldest debates in philosophy. After all, it is about the distinction between knowledge and reality. Knowledge is considered our view about something that, in reality, is 'actually the case.' In other words, knowledge is a reflection, or a mental image of something external, as shown in the figure below.

In this picture, the black arrow represents the process of creating knowledge, which includes perception, cognitive activities, and the exercise of pure reason. This is the picture that physics has come to accept. While acknowledging that our perception may be imperfect, physics assumes that we can get closer and closer to the external reality through increasingly finer experimentation, and, more importantly, through better theorization. The Special and General Theories of Relativity are examples of brilliant applications of this view of reality where simple physical principles are relentlessly pursued using formidable machine of pure reason to their logically inevitable conclusions.

But there is another, alternative view of knowledge and reality that has been around for a long time. This is the view that regards perceived reality as an internal cognitive representation of our sensory inputs, as illustrated below.

In this view, knowledge and perceived reality are both internal cognitive constructs, although we have come to think of them as separate. What is external is not the reality as we perceive it, but an unknowable entity giving rise to the physical causes behind sensory inputs. In the illustration, the first arrow represents the process of sensing, and the second arrow represents the cognitive and logical reasoning steps. In order to apply this view of reality and knowledge, we have to guess the nature of the absolute reality, unknowable as it is. One possible candidate for the absolute reality is Newtonian mechanics, which gives a reasonable prediction for our perceived reality.

To summarize, when we try to handle the distortions due to perception, we have two options, or two possible philosophical stances. One is to accept the distortions as part of our space and time, as Special Relativity does. The other option is to assume that there is a 'higher' reality distinct from our sensed reality, whose properties we can only conjecture. In other words, one option is to live with the distortion, while the other is to propose educated guesses for the higher reality. Neither of these choices is particularly attractive. But the guessing path is similar to the view accepted in phenomenalism. It also leads naturally to how reality is viewed in cognitive neuroscience, which studies the biological mechanisms behind cognition.

The twist to this story of light and reality is that we seem to have known all this for a long time. The role of light in creating our reality or universe is at the heart of Western religious thinking. A universe devoid of light is not simply a world where you have switched off the lights. It is indeed a universe devoid of itself, a universe that doesn't exist. It is in this context that we have to understand the wisdom behind the statement that 'the earth was without form, and void' until God caused light to be, by saying 'Let there be light.'

The Koran also says, 'Allah is the light of the heavens and the earth,' which is mirrored in one of the ancient Hindu writings: 'Lead me from darkness to light, lead me from the unreal to the real.' The role of light in taking us from the unreal void (the nothingness) to a reality was indeed understood for a long, long time. Is it possible that the ancient saints and prophets knew things that we are only now beginning to uncover with all our supposed advances in knowledge?

There are parallels between the noumenal-phenomenal distinction of Kant and the phenomenalists later, and the Brahman-Maya distinction in Advaita. Wisdom on the nature of reality from the repertoire of spirituality is reinvented in modern neuroscience, which treats reality as a cognitive representation created by the brain. The brain uses the sensory inputs, memory, consciousness, and even language as ingredients in concocting our sense of reality. This view of reality, however, is something physics is still unable to come to terms with. But to the extent that its arena (space and time) is a part of reality, physics is not immune to philosophy.

In fact, as we push the boundaries of our knowledge further and further, we are discovering hitherto unsuspected and often surprising interconnections between different branches of human efforts. Yet, how can the diverse domains of our knowledge be independent of each other if all knowledge is subjective? If knowledge is merely the cognitive representation of our experiences? But then, it is the modern fallacy to think that knowledge is our internal representation of an external reality, and therefore distinct from it. Instead, recognising and making use of the interconnections among the different domains of human endeavour may be the essential prerequisite for the next stage in developing our collective wisdom. 

Box: Einstein's Train

One of Einstein's famous thought experiments illustrates the need to rethink what we mean by simultaneous events. It describes a high-speed train rushing along a straight track past a small station as a man stands on the station platform watching it speed by. To his amazement, as the train passes him, two lightening bolts strike the track next to either end of the train! (Conveniently, for later investigators, they leave burn marks both on the train and on the ground.)

To the man, it seems that the two lightening bolts strike at exactly the same moment. Later, the marks on the ground by the train track reveal that the spots where the lightening struck were exactly equidistant from him. Since then the lightening bolts travelled the same distance towards him, and since they appeared to the man to happen at exactly the same moment, he has no reason not to conclude that the lightening bolts struck at exactly the same moment. They were simultaneous.

However, suppose a little later, the man meets a lady passenger who happened to be sitting in the buffet car, exactly at the centre of the train, and looking out of the window at the time the lightening bolts struck. This passenger tells him that she saw the first lightening bolt hit the ground near the engine at the front of the train slightly ahead of when the second one hit the ground next to the luggage car at the rear of the train.

The effect has nothing to do with the distance the light had to travel, as both the woman and the man were equidistant between the two points that the lightening hit. Yet they observed the sequence of events quite differently.

This disagreement of the timing of the events is inevitable, Einstein says, as the woman is in effect moving towards the point where the flash of lightening hit near the engine -and away from the point where the flash of lightening hit next to the luggage car. In the tiny amount of time it takes for the light rays to reach the lady, because the train moves, the distance the first flash must travel to her shrinks, and the distance the second flash must travel grows.

This fact may not be noticed in the case of trains and aeroplanes, but when it comes to cosmological distances, simultaneity really doesn't make any sense. For instance, the explosion of two distant supernovae, seen as simultaneous from our vantage point on the earth, will appear to occur in different time combinations from other perspectives.

In Relativity: The Special and General Theory (1920), Einstein put it this way:
'Every reference-body (co-ordinate system) has its own particular time; unless we are told the reference-body to which the statement of time refers, there is no meaning in a statement of the time of an event.'

Philosophy in Schools (2008)

From The Philosopher, Volume LXXXXVI No.1


By Martin Cohen and Lisa Naylor

The Philosophical Society of England has long championed 'philosophy in schools', and over the years has published several articles on the topic. In 1952, Bernard Youngman's strategyset out in an article for the Journal, for a philosophical education was copious amounts of Bible study, whereas nowadays Philosophy in Schools is portrayed as a kind of antidote to religion, a position both explored and advocated at book length by Stephen Law in The War for Children's Minds. But at least Law would agree with Youngman that the educator's task involves leading 'the young untutored mind towards love of wisdom and knowledge'. And both follow the philosophical principle that the teacher (in Youngman's words) "must value freedom of thought and revere independence of mind; he must at all times be as Plato so succinctly put it - midwife to his pupils' thoughts".
In the dark days of Madame Thatcher, and the UK of the 1980s, when everyone 'knew the price of everything and the value of nothing', philosophy was out of fashion at all levels of education. But these days Philosophy is undergoing something of a resurgence, particularly in UK schools. Not for nothing did that cynical marketing phenomenon, Harry Potter, designate his first task as 'the search for the Philosopher's Stone'. Because, philosophy, however interpreted, has something about it that is appealing to children, intellectuals and hard-nosed accountants alike.

And even if it is sometimes not quite clear which group is driving it, certainly there are now schools dotted all around Britain dipping at least a small toe into philosophy, from small rural Primaries to large urban Grammars. There are a lot of deep philosophy of education and teaching methodology issues raised by these projects. In particular, philosophy like this (unlike the elitist and stultifying French /Philosophy Bac') is part of the shift away from learning content to towards 'thinking skills', and indeed listening and communication skills. Philosophy for children in this sense is just part of a "creative curriculum", made up out of Music, Dance, and the Arts.

One school that has made a particular campaign out of the approach is a small London primary school called Gallions (in E6) which claims that philosophy has cultivated and encouraged creativity, empathy and a sense of self-worth throughout the school. After reinventing itself in this philosophy-inspired way, it claims to have made enormous progress.

"Regular practice in thinking and reasoning together has had an extraordinary impact on learning, on relationships, and on mutual respect within and beyond the school gates", Gallions says in one of its innovative (read: expensive) publicity materials.

Gallions claims to have found the holy grail of education - active, creative, democratic -somewhere in the, by now fairly well-worn, methods of Matthew Lipman, a professor of philosophy in the United States, branded as 'P4C', along with more recent help from SAPERE a sort of British off-shoot busy selling courses in its methods (including 'masters' degrees at Oxford Brookes University).

Made into a commercial brand by Lipman, 'P4C' is an educational approach which promises to turn children and young people into effective, critical and creative thinkers and help them to take responsibility for their own learning 'in a creative and collaborative environment'.

The method invariably involves a warm-up or 'thinking game', featuring what is rather grandly called 'the introduction of the stimulus' but might more prosaically be counted as the presentation of the lesson's theme. The group are invited to discuss and eventually decide exactly what questions they want to discuss related to this theme.

For younger children, 'thinking games' like these are advocated.
Bring an object in (Use a prop): In this, an everyday object is placed in the middle of a circle of children, and everybody in turn given an opportunity to ask the object a question.

Random words: This time, again working in a circle, each child says a word which must be unconnected to the last word spoken. If someone thinks there is a connection between the words they call out 'challenge!' and must explain the link.
(If you think these are not much of 'games', you should try the ordinary lessons )

Naturally , schools being schools, philosophy starts off with 'rules'. There are rules about speaking - not talking when someone else is talking, about not laughing at other people's ideas - and rules about 'listening - letting people finish, taking 'thinking time' to consider other people's ideas before speaking, and connecting new contributions to points previously made. All this is both virtuous and very practical. If children learn little else at school , they learn ways of intreating with others. Too often, the school environment discourages discussion and collaboration in favour of rigid distinctions between 'right and wrong' points of view and hierarchies of knowledge.

In all this, the teacher is there not to teach, but only as a source of information or occasionally a 'referee' ensuring both fairness and perhaps encouraging (assuming, which is a big assumption, that they are able to distinguish) the most interesting lines of discussion from the rest. In short, they act as as 'facilitators' for the groups' learning. 'In a community of enquiry all the knowledge to be absorbed comes from the children', preach the P4C guidance notes. The aim is that the children teach each other. Their choices are aid to dominate the entire process: they construct the questions they consider interesting about the stimulus, they choose the question they wish to debate, and they decide in what way they want to contribute to the discussion.

As a consequence of all this freedom to decide what to talk about, the adherents of philosophy for children claim that the classes learn how to think and express their thoughts in new and often dramatic ways.

Secondly, as children listen to and learn from each other, they are said to practise and develop 'communication skills, such as empathy, patience and generosity. Both individually and as a group they become attentive and supportive of each other.

Regular doses of 'P4C' are claimed to enable even the shyest children to develop such speaking and listening skills. 'They learn that, in order for them to be heard when they have something to say, they have to listen, and listen carefully, to what others say. The cognitive challenge represented by the stimulus, the facilitation that constantly challenges understanding and pushes for greater depth and clarity, and the thrill of being listened to with interest, causes them to develop their vocabulary and grammar. Children are generally seen to increase the length and complexity of their contributions over time.' (From a P4C Handout for in-service teacher training edited by Lisa Naylor.)

They also acquire a vocabulary for expressing unhappiness, discomfort or frustration, which leads to negotiating with other children instead of expressing their feelings through physical means. Playground interactions change.

All this leads to children spending more time reflecting on ideas, and becoming generally more thoughtful and articulate. The ability to reflect on one's own thinking is, after all, we are told, a feature of very able people. And so, the children's improved self-esteem translates into increased academic achievement.

Mind you, if the approach was really as successful and as transformative as its advocates claim, it would seem a pity to restrict it to the drip-feed of accredited trainers and special conferences. After all, the ideas are as old as the slopes of Mount Olympus, and materials abound promising ways to implement them.

Yet, the would-be philosophy teachers are encouraged to think that introducing creativity, much less philosophy into the classroom, requires additional training - more expertise, not less! Since the UK government privatised education, the Internet is full of sites (such as Independent Thinking Limited) offering 'experts' in education, usually seen as a kind of branch of business management. In places such as this, the experts, fresh from successful careers as insurance salesmen or racing car drivers boast of their outstanding qualities under pictures of themselves on yachts:
Attitude, creativity, taking responsibility, genius, goal setting and much more? All the stuff that he had never been told before but was beginning to wish he had. More to the point, he began to formulate the idea of working with young people to take these ideas into schools around the country. 
 As one teacher trainer puts it. No wonder that all too often the claims made for P4C turn out to be inflated, and that the children describing how they have benefited seem to be repeating new educational mantras rather than finding their own authentic voices.

This all goes against the original 'Socratic' principle that the teacher stays in the background, only occasionally asserting themselves if they feel either that the discussion has left the philosophical arena completely - or alternatively, to encourage further consideration fo an aspect that may have been raised but is not being followed up by the others. They act as 'chairmen' of a debate, not as sources of new information or adjudicators, both roles which rapidly lead to the class becoming passive in the process.

But if school teachers find it difficult to stay in the background and give up their role as final adjudicator, (few teachers indeed have this knack) it is equally the problem for philosophy in Higher Education too. How to democratise and stimulate philosophical debate is very much the themes of recent work on Philosophy for 'big children' in universities and colleges these days - particularly those taking philosophy as a foundation course for a more specialised degree. In the 1990s I was myself involved in research, under George MacDonald Ross at Leeds University (later part of the so-called 'Higher Education Academy'). Here, tactics such as 'proctorials', which are discussion groups structured in a very similar way to the 'P4C groups reign supreme.

Because philosophy with children and Philosophy, 'with a capital P', in seminar groups, shares many of the same characteristics. There is, first of all, a wish to stimulate the group into active discussion of an issue, and that requires 'the stimulus'. Puzzling problems and paradoxes are often attractive to students, whereas children may prefer more 'concrete' examples.

Whatever method is used, the important thing is to recognise that the problems are triggers, not material in themselves, just as philosophy should be a process, not a body of material to be passively learned.

One secondary school teacher, Michael Brett, who introduced philosophy to his classes (with children between 10 and 13) with books of short philosophical problems, found that the ones which worked best with school students were ones where 'pure philosophers' would refuse to go, such as the economic ones in (my own book) 101 Philosophy Problems, featuring eminently 'concrete' issues such as the price of stamps, potatoes etc., alongside more traditional philosophy problems represented however as secular puzzles, such as the barber who couldn't cut his own hair (Russell's paradox) and so on.

Another book Michael Brett tried with his classes, published in America, called The Book of Questions, had, as one would hope, lots of questions - most of which were ethical and which he thought they'd like, but ihis experience was that children basically preferred the 'barber', the 'stamps and potatoes'...

As he later summed it up, this seemed to be because: 
Children like to see a point to what they are thinking about: understanding economics, money etc., or the interest of puzzles. They aren't that bothered about questions that bear little on their lives - as they see them. 
When Lisa Naylor says (see below) that philosophy encourages children to become producers of surprisingly abstract thought, it has to be remembered that these abstract issues have first of all been made 'concrete' by being brought into the classroom as tape recordings or even simple objects.

This fact has to be borne in mind when imagining that philosophy for children is an opportunity to introduce questions with no particular answer, debates with no particular purpose. Philosophy is not just anything goes... Of course, it might be too early to ask, that this should also be borne in mind for philosophers at all levels.

Philosophy for Children in a London Primary School

By Lisa Naylor

The experience of classroom teacher and Philosophy novice

My relationship with Philosophy for Children began one June afternoon, in our school hall with my Year 4 class when a philosophy teacher came to the school to demonstrate the method in practice.

The specialist played the children two pieces of 'music': one with bird song and trickling water and another with office sounds and distorted voices. This led to the question: 'What is music?' I felt an overwhelming sense of fascination as I sat and observed this group of children, who I had taught for almost a year, discussing and arguing the question of what music was.

I thought that I was an innovative and creative teacher before this, yet here was someone who was drawing out all these incredibly complex and enthralling arguments with my class. Of course, as a class we talked, but now suddenly there was a forum for talking; a structure. Here, somebody was not only giving permission to spend an hour talking about an abstract subject such as 'what is music?' but providing the tools with which to facilitate meaningful dialogue.

I witnessed children who barely spoke English and children who had very little self-confidence debating fervently whether the sound of rain on the window was or was not music. That was it for me. I was convinced.

The children came out of the school hall an hour later absolutely buzzing. Actually, I'm not sure who was buzzing more; me or the children! The children were desperate to repeat the experience and asked me constantly for the next few weeks 'When are we doing philosophy again?' However, it was approaching the end of the school year and so, apart from talking about the enquiry, we didn't actually get a chance to participate in another session.

The next school year, we decided, as a whole school, that we were going to embrace the approach wholeheartedly and so our first two days back at school in September were spent participating in Lipman's P4C 'level 1' training run (on a commercial basis) by SAPERE. I think it was only when I was a participant myself in a philosophical enquiry that I fully understood the excitement and challenge that the children in my Year 4 class had experienced. As a group of colleagues, we sat and animatedly discussed what art was, the meaning of our existence and a whole host of other issues. I think I learnt more about my colleagues over those two days than I had in the rest of the year put together.

Impassioned by this training, I was very keen to put my newly-learnt facilitation skills to the test on my new Year 4 class. However, things were not so straightforward. My new Year 4 class were an incredibly difficult one. They found it virtually impossible to listen to what other children were saying and in the early weeks, appeared incapable of responding appropriately and non-aggressively to anything that was said. There were a number of children who spent several days a week in a Pupil Support Unit for behavioural issues, as well as a significant number of children engaging in constant low-level disruption.

Due to the difficult behaviour and general attitude of the class, we decided to split the class into two for their weekly philosophy sessions. This enabled us to split up the more disruptive children and gave the quieter children more opportunity to participate. This worked really well for a few weeks and at the children's insistence, it was decided to reunite them for their sessions.
Within a few months, my class's ability to listen and respond appropriately improved almost beyond belief. The children were able to challenge each other's ideas in an assertive and non-aggressive way. They began to show respect for each other as contributors and there was a more co-operative feel to the class. Empathy displayed regularly in the classroom, continued to be displayed in the playground and the children were in trouble outside much less frequently than previously.
 The children developed significantly as critical thinkers, too. The thoughts expressed became increasingly original and the children began to base their judgements on reason. The whole class became more united; the levels of self-confidence rose hugely and everybody who knew the class commented on how different they were. I believe, possibly for the first time, the children felt as though they really were part of a democratic community.

At the end of the school year, the class worked together during playtimes and lunchtimes, to write, direct and act out a short piece of drama, based on bullying. There was no adult involvement in this and what was amazing, was the level of co-operation and teamwork displayed.

I think that what makes 'P4C' so special as an approach to teaching and learning is that there is a real focus on both thinking and interpersonal skills. At Gallions, we have seen standards across the school, including Key Stage 2 SATs results (the main official UK government curriculum measures for Primary schools) rise consistently, since we implemented P4C as a whole school approach. Three years ago, we were ranked one of the bottom schools in the London Borough of Newham for these Key Stage 2 SATs results. Last year, we were in the top twenty. This year we are in the top eight. We are not sure that this is solely down to P4C but we believe the children's ability to link ideas from different curriculum areas and tackle problem- solving issues (in Numeracy, Literacy and science) has improved dramatically , thus raising standards across the curriculum.

One problem that we encountered early on, was how to fit philosophy into a busy primary school curriculum. Our solution was to replace the usual strand of Personal and Social education (PSHE) with the philosophy themes.. We needed to ensure we continued to cover all our PSHE and citizenship objectives by carefully choosing suitable topics. For example, if we were looking at the Rights of the Child, we would use a stimulus which would generate questions on that issue.

Since then, I have witnessed changes I didn't think possible in a very difficult class, as well as a huge rise in self-confidence, self-esteem, levels of articulation, not to mention increased vocabulary, enhanced problem-solving ability and a willingness to take risks.

Running philosophical enquires has completely changed the way I teach, the way the children learn and the way the school is run. As a teacher, I am much more willing now to take risks with my class and less likely to shy away from dealing with difficult or sensitive issues. P4C has strengthened and deepened the relationships I build with the children in my class and given me confidence to not always have the answer.

Philosophy has taught me that there aren't many things in life more important than talking. Not just talking 'chit-chat' but real, purposeful dialogue. Giving children the tools, the language and the opportunity to discuss issues that are really important to them and their lives, is perhaps one of the most important skills we can give.
