Many yearly rituals of Ramadan will continue even as some change in deference to our social responsibility to respect God’s laws in the universe. 

The Muslim holy month of Ramadan will be different this year. Around the world, mosques will be closed, when they would normally have worshipers spilling out onto the street. Extended families will remain apart, when they would typically gather for Iftar to break the fast and share homemade treats. And shopping malls, cafes and streets will be eerily quiet, when they would normally come alive after dark.

Ramadan still began on Thursday evening, though, and in the early hours on Friday morning, households gathered, as they have for centuries, to share a sleepy suhur — the pre-dawn meal.

Even as the world grapples with COVID-19, the yearly rituals of Ramadan will continue. Throughout the holy month, most of the world’s 1.8 billion Muslims will fast between dawn and sunset, spend time in Quranic recitation, self-reflection and prayer in an effort to become closer to God, and give thanks for our blessings. But this year, the prescribed exceptions from fasting for young children, travelers, pregnant mothers and anyone who is sick will now be extended to those feeling symptoms of COVID-19.

And this year, our prayers will include special emphasis on the health care workers, emergency workers and other essential employees who are on the front lines of the fight to protect our communities. In the eyes of God, saving human lives and benefitting humanity are most noble endeavors: The Quran likens saving a life to saving the whole of humanity, and the Prophet Muhammad (upon whom be God’s peace and blessings) says that the best of humans are those who benefit other humans.

Our obligation to help and support those in need also takes on added meaning this year as our neighbors and communities face sickness, grief, economic hardship and the loneliness of self-isolation.

Perhaps the most difficult obligation for many, though, will be forgoing the long-planned gatherings of the season, in order to comply with precautions issued by authorities. But following these measures is a duty of our citizenship and a necessity of our social responsibility to respect God’s laws in the universe. For instance, the Prophet Muhammad — whose belief and trust in God was beyond description — even advised quarantining a town in the event of an infectious disease.

Each of us should take the extra time and space afforded by the pandemic’s social distancing measures as an opportunity for further examination of our connection with God, our families and our core values. This time offers a mandatory retreat from the busy nature of our daily lives and a chance to turn toward God, deepening our faith, knowledge and practice. I hope that imams will offer reminders about these opportunities to their congregations.

This period also forces us to rely on the internet and the technologies built upon it. Our young generations have been well-versed in these technologies ahead of their parents. Throughout history, messengers of God and those who strive for the enlightenment of humanity always used the available cultural tools and practices to spread their messages. We also must take this time to connect with our communities in new ways, including making our spiritual resources accessible to younger generations using their language and their familiar technologies.

The challenges of responding to the pandemic and altering our lives might push some of us to seek people to blame or to criticize. As we enter Ramadan, it is paramount that we devote ourselves to helping those in need, rather than finding others to blame. Even as people, groups or nations with whom we have had past differences may be suffering, each of us must reject as inhumane the thought that anyone deserved a calamity.

In a globalized world, nobody is isolated from a potent problem, be it environmental, medical or economic. This is a time to share data, and to collaborate to find solutions. This is a time to realize our interdependence as nations, as communities and as inhabitants of a global ecosystem — a time to recognize that we all are members of the human family and each have the opportunity to show the true potential of humanity.

As we enter this holy month, it is crucial that we look forward with hope and not despair, which stifles people and progress. Humanity has overcome great challenges in the past, and we will find ways to overcome this challenge, too. If we focus on the opportunities this pandemic presents, we will be able to keep our spirits high and reach the end of this tunnel much quicker.

Our observance of Ramadan will necessarily be different this year. But in many ways it will be like any other year: We will fast, we will pray, we will recite our holy book and we will take time for reflection and charity throughout the holy month. May God enable us to benefit fully from the feast of bounty in Ramadan.

All human beings have similar organs, but each organ has qualities unique to itself and to the person it belongs to. Research has revealed that even some of the genes of monozygotic twins are different [1]. As opposed to the previous assumption that “when it comes to DNA, every cell in the body is essentially identical to every other cell,” it has been found that each cell has a DNA of its own [2]. This uniqueness originates from the fact that the order and number of molecules and proteins are different, which is valid for atoms and sub-atom particles as well. Having spent countless hours on microscopes and spectroscopes, a university professor of mine once said, “I witnessed different structures of iron atom each time I observed one. We even need to produce a separate periodic table for the iron element alone.”

We also witness that particles have been created uniquely, just like human beings are. From the micro universe (one millionth of a meter) down to femto universe (one quadrillionth of a meter), each particle is called a boson or fermion. When particles are examined to find out in what conditions they resemble each other in the femto universe, doors of a new world will be opened in terms of knowledge and contemplation. According to this new perspective, while the things and events are sometimes explained through mathematical equations and formulations, they are sometimes explained through experiments of thought trying to attain the truth behind them. Pauli exclusion principle is one such experiment.

Pauli Principle

There are around 380 sub-atomic particles [3]. In atomic and subatomic dimensions, two fermions (e.g. two electrons) of an atom cannot have the same set of quantum numbers. Wolfgang Pauli first explained this principle in 1925 and was awarded the Nobel Prize in Physics in 1945 after experiments proved that the theory was correct. This theory has gone down in history as the Pauli Exclusion Principle.

The motion equations of subatomic particles are expressed by their magnetic states. Pauli said that none of the electrons of an atom can share the same quantum state at the same time. In other words, two electrons in the same atom cannot share the physical features such as magnetism, motion, position and velocity in the same state [2].

In addition to the three quantum numbers (principal, subordinate, and magnetic quantum numbers) described so far, Pauli defined a quantum number for the spin of a fermion (e.g. electron). The spin quantum number is related to the rotation of the electron around its axis because an electron rotates around its own axis as it rotates around the atomic nucleus. According to the Pauli Principle, if an orbit has an electron with a spin of 1/2, an electron with a spin of -1/2 can be placed in the same orbit. If we assume that the spin of an electron rotating clockwise is 1/2 the spin of an electron rotating counterclockwise will be -1/2. Thus, with Pauli’s contribution, four quantum numbers were defined for subatomic particles and it was stated that even if the other three quantum numbers were the same, electrons with different spin quantum numbers could circulate in the same orbit.

The Pauli Principle shows that atoms are not identical. This principle also applies to solid crystals, that is, the materials we use daily. The Principle is also able to explain the fact that the ores that make up the element are different, and the fact that there are different elements in the periodic table. With this principle, important properties of superconductors have been discovered.

In 1927, based on the Pauli Principle, German physicist Karl Werner Heisenberg showed that it is not possible to measure the physical properties of a particle, such as the position and momentum, at the same time and that these results can only be expressed with uncertain probability and statistics [5].

This uniqueness also manifests itself in the space we call the macro world. Stars consisting of only neutrons are called neutron stars. A neutron star is very dense: its mass is 2–3 times that of the Sun, but only about 10 km in diameter. A neutron star should theoretically collapse into a black hole, but this does not happen. The reason for this, it has been discovered, is that neutrons that cannot share the same position prevent collapse and that neutron stars remain in balance [6].

The universe has been created with balance, and everything, from the minutest particles to the stars in the outer space, follows their particular courses to maintain the order.

So when it comes to self identity, in what kinds of groups are we most likely to flourish? And if the sociological truism holds that we bond first with those who confirm our identities by being most like us, how large is that group likely to be?

Steven Pinker, in The Blank Slate, states that “The universality of ethnocentrism and other forms of group-against-group hostility across societies, and the ease with which such hostility can be aroused in people within our own society” is one of the greatest obstacles to the extension of identity communities.

Still, for an opener, you can see self and group formation at work in high school cafeterias as clusters of the like-minded create an identity by excluding outsiders, largely through gossip, sometimes around matters as trivial as a dress code, or who owns the latest electronic gadgetry. In effect, they are behaving like little tribes or nations. The fascinating part is the emotional drive to belong, and the fear of exclusion, even from groups arbitrarily defined and ephemeral, including those created in cyber space. These same principles pertain to the 700 gangs which form the social fabric of south-central Los Angeles. Yet, arguably, this same group-making process, through intellectual imagination, might be extended all the way up to the world nation or global community, with each echelon defined by shared interests, activities, values, and memories. A nation, among them, is a mutuality of thinking among persons sharing common purposes. Yet as a principle of social cohesion, it is also emotional, allegiance-oriented, exclusionary, and collectively administered. There is no nation without those who are not members. Nations may also entail chauvinism, loyalty tests in time of threat, and hostility toward non-members. Karl Deutsch famously defined a nation as “a group of people united by a mistaken view about the past and a hatred of their neighbors.” In his view, national groups lie to themselves about who they are as warriors or victims in order to justify their aggression. They can act as gangs. That is an unnecessarily dark view of the national experience, but it gets much brighter as we go along.

According to the traditional dictionary definition, a national bond arises, not only because people share a common geographical territory, but because they practice the same mores, speak the same language, worship the same gods, fight common enemies, participate in the same identifying rituals and traditions, share a common stock of stories and a common history, and are often related to each other through blood ties. Cohesion around sporting events and beer preferences is merely a parody of bedrock national identity, although in a self-effacing manner, Canadians like to start there. But it is inversely conceivable that diverse peoples with diverse allegiances may somehow share a common territory without a sense of national identity, because most of those listed characteristics typically defining a nation are simply not shared by the members of pluralistic societies. So if such populations are to find an identity center for themselves in a nation, they really have only three options.

One is to redefine themselves around more vague, generic and inclusive categories of nationhood. Another is to impose uniformity through the melting pot, the Lord Durham solution, through enforced and universal education, imposed official languages, an official history, and official social rituals in the search for a common brand of allegiance. A third is to choose a new concept under which they can unite themselves as a secular community and forget about being a nation altogether. In my view of Canadian practice, we are currently pursuing all three solutions at once. The third option entails falling back upon the universals of our humanity. We might simply acknowledge the common desires and instincts of all humankind as members of the global village, and we might view Canada as a piece of this village in which we listen to each other’s first national stories in a spirit of good will. Is that not the mandate of the Canadian ministry of multiculturalism? To be sure, it would seem only right that we remain free to express the national imperatives of our birthplaces, our mother tongues, our religions, and our respective ethnicities, yet such practices appear to obstruct the formation of a specifically Canadian national identity-or maybe not? The point is very much up for discussion.

Let’s return for a moment to the second option, the nationalist teach-in for all citizens. While recognizing diversity, national governments may also recognize the value in proactively promoting a national brand, but it is a challenging enterprise, because a meaningful nationalism cannot be bought with jingoism, cheerleading, and trinkets, or bread, circuses, and revisionist history. Identity as a mind-state entails a combination of pride and duty that is somehow earned and experienced, who knows exactly how? It is something we instinctively desire, yet identity arises only when we feel emotionally drawn to the collectivity of minds, values, and practices that constitute a nation-the argument becomes circular. We may well wonder how such emotional allegiances may best be fostered. It is a point to which I will return. But it must also be lamented that nations may also include stories of failure; in fact, our literature is full to overflowing with them, and they are studied in our university classrooms with empathetic attention. From that perspective, a lament for our national failure to create a national home for new Canadians may be our most common and unifying characteristic; it is an obsession among our literary critics.

There are many stories to choose from, but I am most immediately reminded of a touching personal narrative written by Elena Maccaferri and translated by her sister as A Bench on Which to Rest. Maccaferri came to Canada from a small village above Bologna, lured to a better life by an Italo-Canadian who promised marriage, but failed to meet her at the dock upon her arrival. A hard and lonely life followed, until she was at last found by a man who had also come from her village. She went on to raise children here, who grew up Canadian in soul and spirit, but Elena could never find a true home away from her native mountains, and was overwhelmed by nostalgia. At last, when her children were grown, she returned to Italy, only to discover that all she once knew had vanished. Canada had found no place in her emotions, but had succeeded only in alienating her even from her own children.

Thomas Henricks stated that “for the most part, people experience personhood in the terms that their host societies offer them.” But that does not always happen, and when that host society somehow fails to offer acceptable terms around which personal values can flourish, the story becomes tragic, as it was for Maccaferri. It was a crisis in personal identity in relation to a nation. And while I’m telling stories about the inability of a host nation to inspire allegiance, I’ll mention another, which goes back to my bachelor days as a young Carleton professor. I had just exhausted my resources on a six-bedroom fixer-upper in Ottawa south with rooms left over to rent out to students. In that little community we had a mysterious roomer who never joined in our collective kitchen exploits and conversations. That was not a problem in itself, but his place in the household came to a strange crisis, nevertheless, when one afternoon a couple of the other students found him in the kitchen counting out huge piles of change. He explained simply that if the laundromat owners were so stupid in their choice of coin boxes, they deserved to be robbed. In no time I had a report upstairs, and went down for an account of my own. It was a sad litany: that his father had come to Canada with promises and expectations, and that to his mind this country had ruined him, giving him only custodial work to do. In his disappointment, he had trained his children to blame the entire country, giving them carte blanche to recover his losses any way they could. The laundromat theft had been conducted as a grievance against the nation. Any Canadian was thus a fair target, and revenge could be taken indiscriminately. What bizarre turns the idea of nation can take; it is a reminder that dialogue can help.

When social groups are organized around adhesion to extended clans or tribes, as they were among the First Nations of the New World, we have an early example of the tribal-nation as a tight working survival community sharing a single culture, and calling for unflinching loyalty. But it was only after the long hiatus of the Dark Ages, and a pre-Renaissance period characterized by city states and assorted feudal principalities that the modern nation emerged in conjunction with the political institutions that framed the autonomous state.

The sixteenth century was the first great age of nation building, with England leading the way under the Tudors. And what an experiment it was. A poem I teach nearly every year is entitled The Faerie Queene, written by Edmund Spenser. It was, unabashedly, a national epic which, by chivalric and allegorical example, set out to teach its readers the great civic virtues upon which the new nation could build, including loyalty to the queen and a sense of duty in the cause of right and justice.

Of course, there is nothing like war and the threat of invasion to quicken a sense of common cause and rouse a sense of national fervor. This is simply a by-product of the craving for self- protection which can only be realized where there is a feeling of all-for-one and one-for-all. Canadians still construct some of their strongest moments of national identity through recollections arising from the First and Second World wars. They are noble stories in which we all can share, dealing with a nation coming of age through the baptism of sacrifice. And we have been reminded at times that the nation expects such matters to be treated with ultimate respect and honor. On these occasions the self is lost for a moment in the experience of the nation, and in that regard it is an experience of extended identity, a national ritual that contains the self within the group. The spiritual philosopher, Fethullah Gulen, extends that loss of self in a nation into a hope for a collective future: “Any nation that liberates itself from the deadly web of selfishness and egoism, stereotyping, excessive entitlements, fear of the future, long-lasting hatred and hostility, and at the same time respects the freedom of ideas and beliefs, while turning away from oppressors, as well as giving rights to the innocent, will surely experience long life.” That requires not only self-investment, but collective monitoring and the mastery of the dialogic self in each member. Such a nation must seek to amplify the positive qualities of experiential identity at the national level. But how to extend that experience to the optimum level of respectful allegiance is a challenging formula to meet.

We are, in fact, discussing a rather elusive state of mind. What is it like to experience an ideal national allegiance? How will it feel to be a participating member? One part of our nature seeks a spontaneous glow of unconditional brotherhood in a community of homogenous values. Another part realizes, intellectually, that we have a mutually beneficial contractual arrangement with fellow citizens only at a legal and organizational level. The German terms for these, often employed by scholars, are gemeinschaft for the former, and gesellschaft for the latter. The contrast can be understood historically. In the Middle Ages, rural populations spent their entire lives within view of their parish church steeples; their thought preoccupations were concerned with fixed or received views invested in work, rituals, and customs which remained unchanged throughout generations. Such communities had little need for debate or discussion, because everyone knew what the others were thinking. These were societies entirely integrated through common religious festivals, language, history, and traditions. These were experiential quality nations generating a sense of gemeinschaft.

Renaissance societies worked outwards from this communal base toward new identities based on restraint in a secular, legislated, legal, and impersonal society. This new order we might call a second experiential quality of nation, conceived as a partnership or a social contract to promote political and economic order. Both the communal nation and the legal nation are principles of group organization and experience, but they do not share a common ethos. For better or for worse, the modern plural nation has been compelled to redefine itself as a society regulated by law, charters, and citizenship-a gesellschaft. My point is that as societies foster libertarian individualism, much of that intuitive and communal sense of the first experiential quality of nation disappears. We have heard much, since the nineteenth century, about alienation, solipsism, existentialism, the anxieties of modernity, the breakdown of the nuclear family, rapid mobility, and transnationalism.

The longing for a tribal structure in size and cohesion prevails even in modern societies. We might try to replace that feeling at the national level through an equitably administered legal society, through education, and through health and welfare support. But that returns us to the awkward crux. Does a true sense of brotherhood and identity emerge only when there are collective bonds that include language, religion, customs, food and festivals, and life on a village scale? States may structure themselves around welfare nets, global educational systems, and the legal protection of opportunity for all, but there remains intense anxiety over the oneness of our collective national experience.

You know education is always a hot topic. Everybody has a share and interest in education: Parents, educators, government officials, elected public representatives, nonprofit organizations, religious groups, and so on. Besides, there are many aspects of education, such as finance, law, administration, etc. However, do you also think that teachers have long been overlooked regarding their authority in their own classes? Haven’t they been overlooked regarding their professional development, even though they are the backbone of the education system and they need some assistance in their efforts more than ever? It is good if you also think like me. It is even better if you don’t. Thus, you can share your recommendations with me once you see this school where things are done differently than many other contemporary schools. These teachers at this school see themselves as a learning society. They criticized the status quo they were in some time ago, and renewed themselves collectively. I want you to see the product. Let’s start our journey, shall we?

Room 114

We enter through the big doors of the school. Physically, it is not the best school you would ever see, but it can definitely be said that vitality and cleanliness of the halls stand out. The atmosphere is very welcoming; something is different, but it is hard to tell what it is. I point to the very first door on the right hand side. With pride, I ask if you would like to see this classroom. The sound coming from room 114 is not different from the sound that bees make when they work. As we approach the door, I understand that this is Ms. Williams and her eighth-grade students studying math. She welcomes us and tells us, “please come on in; there are some empty chairs over there,” pointing to two empty chairs, and we make our way towards to the back of the class and have our seats. This is a math class, but I don’t see any numbers on the board or equations being discussed. Soon, we understand that they finished the chapter on expressing roots of cubic equations last week, and today they are discussing a person named Omar Khayyam (1044 – 1123 C.E.). Ms. Williams knew that Omar Khayyam was a philosopher, mathematician, astronomer, and poet. She had formed her students into four groups, and assigned each of his professions to a group, so that they could do some research and present their findings to the whole class. I understand what you mean from the way you look at me: you’re sure this is a math class? you seem to be saying. You’re right to ask. Don’t they need to finish a chapter and pass to the next one immediately, and stay focused on the possible topics that are asked at the end-of-year tests?

Let’s hold on to that question; we can ask this after the class is dismissed. The first three groups already talked about his contributions to philosophy, astronomy, and poetry. We feel very fortunate not to miss at least the last group, who talk about him as a mathematician. I can see brightness in students’ eyes, and their excitement to share everything they have learned with their classmates. The first student, Omar who coincidentally happens to share a name with Omar Khayyam, begins. Omar Khayyam was a scholar among many others of his time. He is best known today for his poetry, but his contribution to mathematics was great. He showed how to express roots of cubic equations by line segments obtained by intersecting conic sections… Another student, Margaret continues: his work on algebra was known throughout Europe in the Middle Ages, and he also contributed to calendar reform. The algebra (from Arabic al-jabr) of Khayyam is geometrical, solving linear and quadratic equations by methods appearing in Euclid’s Elements… April inserts that Khayyam also gave important results on ratios giving a new definition and extending Euclid’s work to include the multiplication of ratios.

They continue their discussion, asking how these scholars tried to seek knowledge and an answer to who they were; and the great contributions they made towards peace and understanding among people of different origins. However, I am currently very much impressed and I lose myself in the beauty of these students’ discussion that I have found myself holding my breath and forgot about your presence next to me. It was no different than waking up from a dream when the bell was ringing. Sure, I will introduce you to Ms. Williams. I understand that you want to learn more about the uncommon method she adopted for this class: Ms. Williams, do you have a minute, please?

Of course, she says: “I have some time. It’s break time now.” You ask her about the topic and the way she formed her teaching method: Why would you choose a person from old history to discuss? Why do you want your students to talk about poetry or astronomy or philosophy in a math class? Do you think they know enough math to solve the questions on the end-of-year test? Why did you choose a Muslim scholar? Is this an Islamic or a secular school? Would you… and you realize you have bombarded her with your questions. You halt and smile.

She smiles back and says: “Yes, this is a secular state school. We try to practice secularism in a true sense that we can talk about religion, and bring religious materials to school to study, but we never try to impose these ideas into our students’ minds. They actually study very different kinds of perspectives, and they enjoy it very much. We take each student as a whole. Since our topic was roots of cubic equations, and Omer Khayyam was the father of the idea, you happened to see this example.”

“But why would you touch on different areas of study in a math class?” You say without taking a second breath.

Ms. Williams smiles again. “This is very common in our school. I am sure Mr. Wraga next door will also get into some math in his literature class since he knows my course syllabus. We try to keep our teachings interdisciplinary as much as possible. I receive feedback that kids enjoy it greatly. I understand your concern about the tests. However, testing is the very last thing we think of. Most of our students do well at those tests anyway, and those who cannot do so well are seen to be still successful mostly as artists or musicians…”

There is a long pause and silence now, but hurricanes are happening in our minds. How is it possible? What kind of philosophy is this school following? Is it the principal who leads these teachers like a conductor leading an orchestra? As Ms. Williams answered our questions, more questions kept popping up in our minds. The bell rings again, and the break is over. We thank her for letting us sit in the class. We make our way back to the hall again, and I am already elated with the intelligence of these students. You look at my eyes without saying a word, and smile: Room 115?

Come and see them in their graves.

Only a large shirt is their share

And even those, without sleeves

Dignitaries they had been

With servants standing before them

Now come and see, you can’t tell,

The late masters from their men

We encountered Judaism at the local synagogue, Hinduism at a Vishnu temple in a nearby city, and Islam at a mosque in the suburbs. We could also have studied Buddhism, Sikhism, and two other branches of Hinduism since there was a meditation society, a Gurdwara, and Shirdi and Jain temples in the city, as well as five additional mosques. Religious pluralism surrounded us, but we knew nothing about it because religious dialogue was not an ordinary activity.

Since taking students on such interfaith field visits was not common practice at the time, it stirred a mix of reactions. Many students approached the project with eager curiosity; they were rainbow optimists, following an arc of hope and expecting good at its end. Other students were reluctant, apprehensive, and afraid of the unknown; they armed themselves with intellectual rocks of protection for their worldview. Some parents even called my office to express their concern about the nature and purpose of such study for their children. Could curiosity weaken their child’s faith, the parents wondered. Even though religious pluralism has been a reality throughout human history, and is certainly an element of our societies today, for many people, then as now, it has remained a distant reality, remote from the routines of daily life. When the opportunity for an interreligious encounter is offered, it can evoke both curiosity and fear. As human beings we are equipped to wonder about and seek the new or unknown, but we are also endowed with a certain caution about, even fear, of what is different. Both of these reactions have characterized the debate about religious dialogue today, often to the irritation of one another, as students have encountered in classes. But both of these approaches have something important to share and should be heard.

Enthusiasts for religious dialogue bring a desire for mutual enrichment and learning, and a confidence that coming to know one another better will bring benefits for all. The rock-wielding cautious fear that interreligious dialogue is a dangerous and misguided endeavor brings a deep sense of what is treasured and unique in our own traditions that must not be lost or sacrificed to the inevitable encounter. In listening to the concerns and hopes raised by both voices, it can become clearer what interreligious dialogue is not and also what it is intended to be; caution and enthusiasm together can shape encounters among various believers that are fruitful and inspirational.

The mirror of dialogue A frequent concern raised about dialogue is that it will be a disguised effort at proselytizing for conversions to one faith or another. This is certainly not the intention of genuine interreligious dialogue, and this approach should not be brought to the table of dialogue. Faithful and committed believers of a religious tradition are asked to respect the faithful believers of other religious traditions who share a similar devotion and joy in their commitments.

The holy Qur’an states, ‘O mankind, indeed We have created you from male and female and made you peoples and tribes that you may know one another.’ (49:13) The Roman Catholic Church also exhorts her members that ‘through dialogue and collaboration with the followers of other religions…they recognize, preserve and promote the good things, spiritual and moral, as well as the socio-cultural values found among them.’ (Nostra Aetate, 2)

Of course, believers engaged in dialogue will explain with great enthusiasm the faith that they hold dear, but the primary goal of interreligious dialogue is simply to listen to and come to know others. Far from converting believers away from their faith, interreligious experiences usually deepen original commitments. It has been suggested that ‘those who know only one, know none.’ In comprehending another faith, we come to a far deeper understanding and appreciation of our own belief. In our reflection in the Other, we come to see ourselves anew.

In my own experience over the years, leading dozens of classes on field visits to various houses of worship, I observe similar outcomes each time. Though the fear of parents that their children might be lured into a conversion by a persuasive speaker would seem to have even more ground today, since students often have very little religious knowledge when entering the classroom, the common response of students is not conversion to a new tradition but rather a renewed interest in the faith traditions of their own families. Even when students have been raised by their parents to make their own choice, as if a faith tradition were simply a matter of consumer preference in the marketplace, I have found that they want to ‘come home.’ If home does not provide much religious substance, to find spiritual roots students are more likely to turn to their grandparents than to convert simply because of exposure to a new tradition.

Not the baking method Sometimes the cautious question if interreligious dialogue is aiming to bring religions together in a way that creates a new and improved religion, a combination of the ‘best of all,’ so to speak. The technical term for this is syncretism, but it is also (derisively) known as the ‘baking method’—take a little of this and a little of that and a little more of something else and bake it into a new tasty religion for all to follow. This approach, too, is certainly not an element of genuine interreligious dialogue but rather is an attitude born in the individualism of consumer culture—finding something that suits my taste. True interreligious dialogue takes places among faithful and committed believers of established religious traditions who intend to remain that way. It is not a casual comparison of recipes, but a sincere effort to know one another as we are.

Again, in my own field visit experience with classes, it is precisely when faced with the devotion of a believing community at worship that students are inspired to look at their own tradition to see what they have missed. The prayer practice of Islam has led students to discover the Angelus and the Liturgy of the Hours in the Catholic tradition, or the practice of daily scripture devotion in other Christian traditions. This is not syncretism, but rather interfaith inspiration that strengthens.

But can we disagree? Two other objections I have heard raised about dialogue seem to be from opposite sides of the same coin. First, some fear that participants from other traditions will judge our beliefs or practices and condemn them unfairly because they are based in a different set of values or cultural apprehension. The second worry is that as we listen to others we may hear some things with which we profoundly disagree but, prevented from expressing this by the ‘etiquette’ of dialogue, be reduced to tacitly supporting relativism. I believe the question raised by both objections is essentially the same—where is Truth to be found and how do we act upon it? Can we truly listen to one another without discovering all the places we disagree? And what then do we do with that disagreement?

In response to these foundational questions, two points must be kept in mind. One is that each of us has the human obligation to sincerely seek for Truth, for the objective reality at the heart of the universe. This will necessarily entail that we must make judgments for ourselves in regard to various Truth claims. However, it is important to be clear that the basic purpose of interreligious dialogue is simply coming to know and understand those varied claims made by religious traditions; we are not expecting to reach agreement on them in regard to religious doctrine or practice.

The second point clarifies this further. In coming to know one another we may find real and significant differences in the lived moral consequences of our beliefs and practices. It is very important to remember that we do not grapple with these differences in interreligious dialogue. Rather, the proper sphere for that work is in political debate. In a multicultural democracy we engage one another in political discussion, convincing one another of the value and efficacy of our moral vision and why it should prevail in law. It is at the table of interreligious dialogue that we come to understand one another, but it is at the table of political discourse that we try to persuade one another, not for a religious conversion to our Truth claims, but for a moral consensus regarding lived values. The conversation at each table is better because of the work of the other.

Wisdom of the heart With these cautions and clarifications in mind, we are better able to hear the enthusiasts in explaining the benefits of dialogue. At center is the inspiration that dialogue can renew our own spirituality. I certainly see this result in the classroom. Most parents have encountered a stage in their adolescent children’s development when they listen to advice with greater openness if it comes from someone other than their parents. Interreligious experience is a similar inspiration, and not just to questioning teens, but to developed believers as well. Hearing others share their deepest convictions about the Divine can renew the vigor of our own quest for holiness. Often in dialogue our hearts meet before our heads agree and we find that it is in the wisdom of the heart that God’s presence is made known. Understanding one another and how very much our traditions hold in common can bring mutual enrichment on local and global levels as well. Citizens in society are better equipped to live in peace and work for justice when they have had interreligious encounters to share and learn about one another. Prejudice is exposed and broken. In the aftermath of the 9/11 tragedy, I received several email messages from former students who expressed their gratitude for the field visits they had made to mosques in earlier years. Having met Muslims as prayerful, welcoming human beings was helping them, at that difficult national moment, to share with others that Islam is not a religion of terrorism and all Muslims were not responsible for, nor rejoiced in, the events of that tragedy. They were able to be voices of peace in the midst of great national confusion.

Sustained encounters When it is possible for interreligious dialogue to become a sustained encounter among individuals or groups, over time it can begin to reshape those who participate in profound and beautiful ways. Though most of my students are only able to have one or two field experiences during their study, I am privileged to be on every trip, returning year after year and building friendships with the generous believers who host our visits. The encounters have gradually ceased to be between ‘us’ and ‘them,’ learning about their ways and teaching them our ways. Instead, as we have continued to listen and share, we find ourselves becoming a ‘we’ in our common humanity, a commonality that honors, and yet also transcends the differences of culture and faith, of geography and economics. I am deeply grateful to my dialogue partners for the depth and strength they have added to my own faith journey.

Religious pluralism is a reality; it surrounds us and permeates the culture. But interreligious dialogue is a choice. Burying our heads in the sand and throwing rocks when we come up for air will not change anyone’s heart, including our own. Instead we can choose to move toward a mind of greater perception, a heart of greater love, a world of greater peace, by accepting the invitation to know one another, carefully and respectfully crossing the arc of dialogue into mutual understanding.

According to a study by researchers of the Human Footprint Project [1], humans have influenced 83% of the earth’s surface. The study is based on four factors: population, travel routes, land use, and lights. One of the findings of the study shows that an average American is responsible for more carbon emissions in one year, than a person in Tanzania in a lifetime. This significant difference is certainly related to the average lifespan, income, culture, and climate. However, do any of us have the rights to disturb the environment more than others? Are we consuming something that doesn’t belong to us, and leaving an unsustainable environment for future generations? To answer these questions, it is imperative that we understand and acknowledge exactly what we have inherited, what we are responsible for, and what we will leave to future generations.

Our influence on the earth and environment in a general sense is not limited to the consumption of goods. One of the most influential yet less-visible traces is the footprint we leave in the digital environment. There are active or passive traces left in a digital environment by personal activity. An active trace is left when personal information is released by a person himself, whereas a passive trace (digital shadow) is left when personal data is collected during personal activity. These traces, also known as digital footprints, can spread very quickly and may reach to millions in a very short time. One can leave digital traces by simply visiting a website, sending a blog post, or posting a photo or message to a friend’s website.

Our digital traces affect the environment in many ways. Every trace takes our time to generate it and for others to read it. It consumes storage and network resources on the server that increase the costs, power usage, and eventually our carbon footprint, or the total greenhouse gas emissions. We need to seek a balance in our use of digital media in order to utilize the benefits efficiently and to minimize our consumption of time and other resources.

Have you ever wondered “how often a person leaves digital traces behind every day?” or “how much of our privacy are we sharing with others?” A recent study reveals some figures about the size of the digital universe as 281 billion gigabytes (GB) for 2008 and 1.8 billion terabytes for 2011 [2]. The digital trace generated by the average person on a daily basis was about 45 GB in 2008. This includes private information such as emails, photos, VOIP calls, and instant messages.

How about passive digital traces we leave behind by credit card purchases, bank accounts, phone records, web searches, general backup data, medical and hospital records, surveillance cameras, and so on? There are more passive traces collected than our active digital traces, which provide more personal information.

As of 2006, there were over 1 billion Visa credit cards worldwide and counting [3]. Credit cards give a lot of private information about a person: stores we prefer, movies we watch, places we travel, books we read, prescriptions we take, rent and utility fees we pay; mainly our lifestyle is hidden in our credit card statements. It might contain a lot of details we want to keep private. We can easily learn a lot about our social life just by analyzing one of our credit card statements.

Web searches provide more insightful information about a person. 113 billion web searches were conducted in July 2009, a 41 percent increase compared to 2008 [4]. Besides all the information we leave with our credit card, web searches may show things we have not actually done. They contain information about our future plans, such as travel, job search, health related issues, meetings, and education. Websites can provide smarter search results and personalized advertisements according to our search habits. Search engines even know how fast we type or process information, our typos, languages we speak, how smart we search, and even our physical location from the IP address.

Today many cars have GPS (Global Positioning System) capabilities and smart phones have GPS sensors. GPS devices can show our exact location anywhere in the world, provide turn-by-turn instructions from one location to another, provide a list of nearby stores, and warn us about traffic problems. A recent market research [5] estimates that the mobile location technology market that crosses the US will be $75 billion by 2013 with growing usage of GPS capabilities in automobiles and consumer electronics. Beside all the benefits, GPS devices leave an important digital trace behind, our exact location, which can be stored for later use or tracked by third parties.

Even if a person doesn’t have a GPS sensor with him, there are cameras all around the city that can help capture one’s location. We can see cameras inside and outside of the banks, stores, traffic lights, and even closed-circuit TV (CCTV) surveillance cameras in some cities. The total number of CCTV cameras in England is 4.2 million, or one for every 14 people according to an estimate. According to Scotland Yard, one crime per 1,000 CCTV cameras is solved in a year [6].

The number of smart phones increased 13.9 percent worldwide, compared to 2007, and reached 139 million in 2008 [7]. Many smart phones have real-time video streaming capabilities and are widely used. Users upload hundreds of thousands of videos per day to YouTube about themselves or people around them. Considering that there are thousands of video sharing websites like YouTube, sharing videos on these websites lies at the center of important privacy concerns. There are websites to share videos, photos, music, location, blog posts, and personal updates. With the rise of the micro-blogging trend, we can see real-time updates about a person on websites like Twitter. This allows us to track every minute of a person’s life.

Social networking is a new way of communication. Many websites provide tools to build online communities of people, who want to share and learn interests and activities of others. We can build our friend list and share photos, videos, and updates about our life. According to Nielsen Online’s report on Internet usage in June 2009 [8], users spent an average of 4 hours and 39 minutes during June on one of the most famous social networking sites, Facebook, which has 87 million visitors. Normally these websites provide privacy settings to limit who can access our friend list, photos, or other information. Since most of the people don’t refuse friend requests, it is very easy to be added as a friend and get access to all the private information of people we do not even know. Once we get accepted by a person as a friend, it gets easier to be accepted as friend by his/her friends, since we have mutual friends. These connections increase our friend list exponentially.

I had known about this process for some time, so I wanted to confirm it myself by setting up an account with fake information and identity on Facebook in 2008. I selected a college and input random personal information to my profile. I visited some group pages on Facebook and joined them. Then Facebook started to offer possible friend lists that have common interests with me. I started to make random friend requests to many users on these lists. In one day, I had around a hundred friends in my list that I don’t know personally. As a friend on their list, I have access to all information they share with others. Most of the users are using default settings and are not aware of privacy issues. Even if we are careful about all these settings and our privacy, our information is accessible by website managers. Digital traces left by users are valuable commercial assets for companies, and most of them share or sell this information to third party companies which provide online advertisements, products, and services.

There is a positive side of these digital traces. Websites provide better recommendation of products and services, targeted advertisements, smarter search results, and personal news. Entertainment businesses can provide appropriate suggestions by using location services. However, erasing our digital traces is difficult or even impossible in some cases. To protect our privacy and identity, it is essential that we are aware of places our personal information is stored. It is the responsibility of websites to protect user’s data. However, it will be a good start to be aware as users of our traces on the digital universe and to share personal information carefully.

With various effects on our natural and social environment, digital traces are one of the most influential and yet less known by-products of consumption. It is an important responsibility for us to decide how we affect our environment, how we spend our time, and what we are going to leave to future generations. With all the unique values given to humans, we need to learn to make meaningful contributions and carry more responsibility for our actions, especially in the digital world where boundaries are unlimited.

Did you know that we are actually stardust? Most probably, you didn’t. Nuh Gedik lifts our eyes from the ground into the depths of space. In his thought-provoking article he describes how a star explodes to present a marvelous celestial supernova show. Supernova explosions are actually “the only source of heavy elements, including iron . . . the carbon that makes our cells, the hemoglobin that carries oxygen in our blood, and basically almost everything in our body are all made of elements produced in these explosions.” “Supernova Explosions” explains more not only about stars, but also about our chemical make-up.

The mysteries of nature are disclosed a bit more by another show, this time on earth: The glowworms of the Waitomo caves in New Zealand are bioluminescent flies which present stunning shows that rival the star-lit sky at night. The theory of evolution fails to explain the complex nature of this minute insect which can yield light at an output of 100% with no energy wasted as heat. Have we yet reached such a capacity of power production? Safak Ozturk tells us more in his “A Message from Glowworms.”

Inefficient use of time is something that we all complain about. Everyday, we get up in the morning and rush to our jobs to start work in time. However, today, more frequently than ever, we end up having spent our days having done little more than checking several e-mails, making telephone calls, and going to meetings to change schedules and deadlines. Cafer Tayyar Yavuz highlights the importance of even the smallest slice of time we usually ignore and explains how better efficiency can be achieved in our use of time.

Enviromnental damage ramains a growing concern. Despite rigorous energy efficiency programs and research and development (R&D) efforts on cleaner energy technologies in most developed countries, no developing country views these as priorities. And they have a case: Developed countries, which enjoyed high economic growth for decades by ignoring the environmental consequences, are hindering developing countries’ economic growth. On the other hand, representatives from developed countries say that we are all in the same boat and will sink together if developing countries do not pay attention to environmental consequences.

In December 1997, world leaders gathered in Kyoto to address the problem of global warming and to decide which countries should cut emissions and to what extent. Not surprisingly, developing countries objected to any restriction that might limit their economic growth. Such discussions will become more intense in the aftermath of the Kyoto Protocol.

This article will not address the issue of environmental reparations. Rather, it will discuss the energy markets’ current situation and short-term future trends.

Basic Properties of the Energy Systems

Present-day energy systems have several basic characteristics. All policy makers dealing with energy systems should know these basics by heart.

First, energy systems develop slowly because they require significant capital and infrastructure that can be replaced only gradually. There are two important consequences resulting from this fact:

•Intense capital requirements are a strong barrier to average-sized firms. Thus, energy systems are seldom run by private enterprises. In most countries they are constructed and run by the state, and a separate government body deals with energy issues. Energy systems have been dominated by heavy regulations even in most market-oriented economies. The recent trend of deregulation is an exception rather than the norm.

•Even if a state realizes that current energy systems can be improved significantly (e.g., switching to other fuel types or deregulating the market), making changes to a huge, functioning infrastructure is a slow and painful process. It is relatively easy to make changes during the initial stages of an energy system. But as time passes, this becomes more difficult.

As in most cases, good planning is essential. A state must be very careful when building its energy systems, and should pay attention to underlying energy market trends. Important lessons can be learned from the long history of mistakes committed by developing countries. And if a developing country fails to keep up with recent trends, it may find itself trapped by its own hands in an inherently inefficient system for decades.

Second, energy systems are heavily reliant on fossil fuels. Historically, coal has been a prominent energy resource in most countries. Despite its widely acknowledged negative impact on human health and the environment, it still dominates energy systems in such developing countries as India and China. In most countries, oil is the primary energy source.

Oil was one of the most influential key factors of the twentieth century. Just by looking at the traffic on our teeming highways or the modern political landscape, we can understand how profoundly oil has changed the way we live and handle international politics. In the light of the oil crises of 1973 and 1980, the reverse-shock of 1986, and another crisis during the Gulf War of 1990, the need to diversify away from oil becomes abundantly clear.

Environmental concerns also support the case against oil. This is how natural gas, a slightly cleaner fossil fuel, gradually entered the picture. Given the current energy systems’ dependence on these fossil fuels and the fact that energy systems change slowly, oil, coal and natural gas will continue to be dominant for years.

Third, the driving force behind the dynamic of switching from one fuel type to another is economics. Fuel types with smaller unit costs survive in the long run. Oil, for example, now has the lowest unit cost (cost per unit of energy) in most regions of the world.1

Given this, cleaner fuel (e.g., solar energy) still have a long way to go before becoming economically viable. Why would you pay $5 for what you can get for $3? Countries that use non-oil energy resources do this for a number of reasons, such as they do not have natural resources and so transporting oil ends up costing more, or they have abundant natural energy resources of other types. But, in general, economics is the most important issue here.

Introducing New Fuels

What trajectory does the unit cost follow when a new fuel is introduced? Consider photovoltaic (PV) cells. The term photovoltaic refers to a family of technologies that convert light directly into electricity. PV technology is an appealing alternative-it is a renewable, environmentally benign, and domestically secure energy source. It is modular and can be scaled up to meet demand.2 However, unit cost is currently high compared to fossil fuels.

A new technology’s unit cost is believed to follow a learning (or experience) curve as a function of installed capacity. As shown in Figure 1, technologies may experience declining costs due to their increasing adoption by society. This decline may be attributed to several factors:

• Technology innovation and manufacturing improvements: Costs may decline due to a better understanding of the underlying science, progress in related fields, or via learning by doing as well as learning by using.

• Economies of scale: Unit cost is a function of total production. Products produced in large quantities have lower unit costs. Most new fuel types have high unit costs, and demand is too low to encourage large-scale production. It almost seems paradoxical. But there are ways to break this cycle. Regulations encouraging usage of new fuel types may be enforced, consumers who have priorities other than cost may be targeted to expand the current market, or the cost may drop low enough for the technology to become attractive even for low production levels.

In achieving economies of scale, consumer demand should he considered. A major concern for the end-use consumer is convenience. The value of oil would be much lower if gas stations were not located all over the country. The same issue applies to fuel cells and electric cars. They will not be as convenient as conventional cars until the proper infrastructure exists.

Since 1960s, cooperative investments by manufacturers and governments have resulted in the accumulation of experience within the solar industry and the subsequent cost reduction of PV systems. Significant cost reductions have occurred in both the PV modules that house the solar cells, and the ancillary components (known as balance-of-system). Between 1968 and 1998, the global cumulative installed capacity of PV modules doubled more than thirteen times, from 95 kW to 950 MW, while costs ($/Wp) were reduced by an average of 20.2% for each doubling.4

Trends for Different Fuel Types

After this overview of energy systems, lets look at the trends for specific fuel types. Figure 2 is taken from International Energy Outlook 2000 (IEO2000), an annual report published by the U.S. Energy Information Administration (EIA).5 It displays projections of energy usage by fuel type up to 2020. The highlights following the figure are summarized from the reports contents.

Coal: Carbon dioxide is a very effective greenhouse gas and contributes significantly to global warming. Since coal is the most carbon-intensive fuel, global climate change debates focus on reducing its use. Coal use also has significant public health consequences, due to particulate matter emissions. Historically, coal has been a major source of energy. Although it has lost market share to petroleum products, natural gas, and nuclear power in the last decades, it remains a key source of energy, especially for generating electricity. In the IEO2000 reference case, coals share of total energy consumption falls only slightly, from 24 percent in 1997 to 22 percent in 2020 (Figure 3). Its historical share is nearly maintained, because large increases in energy use are projected for developing Asian countries, where coal continues to dominate many national fuel markets. China and India are projected to account for 97 percent of the worlds total increase in coal use.

Oil: Oil use will grow in absolute terms, but even optimistic oil supply scenarios predict that its share in the fuel mix will decline gradually. Despite efforts to reduce reliance on Middle Eastern oil, as well as advances in technical capability, new oil reserves are not compensating for depleted ones. The experts estimates of vast oil reserves in the Caspian and Tarim basins proved to be somewhat high, and the latest probes have been partially disappointing. According to EIA estimates, the share of the Persian Culf supplies is likely to increase in the coming years. Economic theory says that prices rise as supply declines. Oil prices have been quite volatile and can be expected to remain so in the future, principally as the result of unforeseen political and social circumstances. Without attempting to predict any crisis, the IEO2000 forecast shows a gradual rise in world oil prices. Oil currently provides a larger share of world energy consumption than any other energy source and is expected to remain in that position throughout the forecast period. Its share of total energy consumption declines slightly, however, from 39 percent in 1997 to 38 percent in 2020, as countries in many parts of the world switch to natural gas and other fuels, particularly for electricity generation. World oil consumption is projected to increase by 1.9 percent annually over projection period. Most of the growth in oil use is projected for the transportation sector, where few alternatives are currently economical.

Natural Gas: Natural gas remains the fastest growing component of global energy consumption. Over the IEO2000 forecast period, its use is projected to more than double in the reference case, reaching 167 trillion cubic feet. The natural gas share of total energy consumption increases from 22 percent in 1997 to 29 percent in 2020. It also accounts for the largest increment in electricity generation. Combined-cycle gas turbine power plants offer some of the highest commercially available plant efficiencies, and natural gas is environmentally attractive because it emits less sulfur dioxide, carbon dioxide, and particulate matter than either oil or coal.

World Energy Consumption Shares Type: 1970-2000

In the industrialized world, natural gas consumption has the largest projected increase among the major fuels, increasingly becoming the choice for new power generation because of its environmental and economic advantages. Its incremental use in developing countries is expected to supply both power generation and other uses, such as town gas and fuel for industry. Despite concerns about the extent of natural gas reserves worldwide, current proven reserves suffice for this markets steady development without a substantial price increase.

Nuclear Power: The prospects for nuclear power are uncertain, despite a projected growth rate of 2.5 percent per year in total electricty demand through 2020. In the IEO2000 reference case, global nuclear capacity is projected to increase to 368 gigawatts in 2010 and then gradually fall to 303 gigawatts in 2020. Aggressive plans to expand nuclear capacity, mainly in Asia, lead to a near-term increase. However, plant retirements in America and other countries exceed total new additions worldwide, and produce a decline later in the forecast. The International Institute for Applied Systems Analysis [IIASA] is one of the authorities on energy issues.

IIASA projections [which extend until 2100] hold a slightly pessimistic view of nuclear energy. Nuclear energy production has stagnated for several decades, and IIASA suggests that this will continue. Currently, nuclear energy is prominent in only a handful of countries. Not many nuclear plants are being built, and existing ones are being dismantled. With large up-front capital costs, plant safety, and recycling nuclear material after dismantling issues, this option is becoming less and less attractive. Public opposition, already strong in the US and Europe, is growing in Asia. Nuclear safety issues moved to the forefront in Asia in 1999 after several leaks at nuclear power plants in South Korea and China, and the serious accident in a reprocessing facility in Tokaimura, Japan. Such events are likely to raise concerns about Asias aggressive plans for nuclear capacity expansion. IIASA predicts that if a safer and cheaper new generatinn of nuclear plants is introduced, nuclear powers ultimate share in fuel mix will grow. Otherwise, it eventually will come to an end.

Renewables: The development of renewable resources is constrained in the IEO2000 reference case projections by expectations that fossil fuel prices will remain relatively low, and that, as a result, renewables will have a difficult time competing. Failing a strong global commitment to environmental programs, such as the limitation and reduction of greenhouse gases outlined in the Kyotu Protocol, it is difficult to foresee significant and widespread increases in renewable energy use. Modest growth in renewabte energy is projected to continue, maintaining an 8 percent share of total energy consumption. Nevertheless, in the long run, as other fossil fuel types become more expensive due to depletion and R&D efforts push the unit cost further down, new opportunities will emerge. Even conservative estimates predict that the worlds energy will rely considerably on renewables before 2100.7

Conclusion

In this article,we highlighted several basic characteristics of energy systems, and drew attention to some underlying trends for particular fuel types. Based on this information, we can say that:Energy systems are capital-intensive and hard to change once they have been built. Therefore, developing countries should track energy system trends closely and build their energy systems according to their future needs. The most important factor influencing the decision of which energy source to use is economics. Until a resources unit cost is competitive with others, it will not enjoy widespread acceptance and usage. Fossil fuels will dominate energy markets in the short run. The shares of coal and oil in the fuel mix will remain relatively constant until 2020, while the market for natural gas will expand rapidly. Nuclear power will survive only if a new generation of safer and cheaper reactors is introduced. Renewables will be the ultimate choice of the future. Currently, however, they cannot compete successfully on cost with conventional fuels.
