As both a scientist and a humanist myself, I have struggled to understand different claims to knowledge, and I have eventually come to a formulation of the kind of religious belief that would, in my view, be compatible with science.
I consider myself a spiritual atheist. I certainly believe there are forces bigger than ourselves, and that we should be searching, individually, for meaning in our lives. But I don't believe there's a supreme being, an intelligence that created everything.
I oppose any belief that contradicts experimental evidence as determined by the methods of science. All beliefs not in such contradiction may be considered as faith. Whether faith in a particular belief is beneficial or not is another matter.
I have for a long time loved fabulist, imaginative fiction, such as the writing of Italo Calvino, Jose Saramago, Michael Bulgakov, and Salman Rushdie. I also like the magic realist writers, such as Borges and Marquez, and feel that interesting truths can be learned about our world by exploring highly distorted worlds.
We live in a highly polarized society. We need to try to understand each other in respectful ways. To that end, I believe that we should make room for both spiritual atheists and thinking believers.
I have always loved magic realism as a form of writing. I have also been fascinated for a long time with the intersection of science and religion.
We're plugged in 24 hours a day now. We're all part of one big machine, whether we are conscious of that or not. And if we can't unplug from that machine, eventually we're going to become mindless.
Novels aren't pedagogical instruments, or instructions in law or physics or any other discipline. A novel has to be an emotional experience, a trip of the imagination, and because science has raised so many issues that concern and affect humans, it's a good starting place for me.
All writers have roots they draw from - travel, work, family. My roots are in science and it is fertile ground for fiction.
If I were not a writer, I would spend more time doing the things that I am already doing, which include doing research in physics, teaching, and running a nonprofit organization with a mission to empower women in Cambodia.
With a background in science I am extremely interested in the meeting ground of science, theology, and philosophy, especially the ethical questions at the border of science and theology.
Music is, of course, a universal emotional experience, cutting across cultures and languages. I studied piano for ten years as a child and consider that experience one of the most valuable in my life.
I think e-mail is representative of our fast food mentality in the United States, where everything has gotten faster and faster, and we're required to respond to inputs more quickly with less time for thought and reflection. I believe that we need to slow down.
Except for a God who sits down after the universe begins, all other gods conflict with the assumptions of science.
I have too many friends who tell me that they spend the first hour of every morning going through their e-mail messages. I'd like to use my time more carefully.
As a scientist, I don't believe science will ever discover whether God exists. Nor do I believe religion will ever prove it.
I've taken a philosophical position on e-mail. Although I think it's a wonderful communication technology, and it has a lot of good uses, it is abused quite a lot.
For me, consciousness is the most interesting unsolved problem of science, and, in fact, we may never know what it is about a particular arrangement of neurons that gives rise to consciousness. Our consciousness, like the air we breathe or like the passage of time, is central to our existence as intelligent beings.
I still will sit down at the piano and play when I am wrestling with something emotionally or just want to move into the musical world.
In a world without future, each parting of friends is a death. In a world without future, each loneliness is final. In a world without future, each laugh is the last laugh. In a world without future, beyond the present lies nothingness, and people cling to the present as if hanging from a cliff.
Thoughts are no more than electrical surges in the brain. Sexual arousal is no more than a flow of chemicals to certain nerve endings. Sadness is no more than a bit of acid transfixed in the cerebellum. In short, the body is a machine, subject to the same laws of electricity and mechanics as an electron or clock.
While people brood, time skips ahead without looking back.
Suppose time is a circle, bending back on itself. The world repeats itself, precisely, endlessly.
There is a place where time stands still ...illuminated by only the most feeble red light, for light is diminished to almost nothing at the center of time, its vibrations slowed to echoes in vast canyons, its intensity reduced to the faint glow of fireflies.
In this world, time has three dimensions, like space. Just as an object may move in three perpendicular directions, corresponding to horizontal, vertical, and longitudinal, so an object may participate in three perpendicular futures. Each future moves in a different direction of time. Each future is real. At every point of decision, the world splits into three worlds, each with the same people, but different fates for those people. In time, there are an infinity of worlds.
Every reader gets something different from a book and every reader, in a sense, completes it in a different way.
So many little lives, amounting to nothing. I ask you: What is infinity multiplied by zero? It is hardly worth our discussion.
You've made something grand, but it will be grander if it has feeling and beauty and harmony.
No one knows the nature of God, or even if God exists. In a sense, all of our religions are literary works of the imagination.
It's not necessarily a large number of people that affect the culture. You don't count the number of influential voices, you weigh them. A hundred people can affect the culture.
Such is the cost of immortality. No person is whole. No person is free. Over time, some have determined that the only way to live is to die. In death, a man or a woman is free of the weight of the past [and the future].
Imagine a world in which there is no time. Only images.
One metaphor for how we are living is that you see so may people with cell phones. In restaurants, walking, they have cell phones clamped to their to heads. When they are on their cell phones they are not where their bodies are...they are somewhere else in hyperspace. They are not grounded. We have become disembodied. By being always somewhere else we are nowhere.
In this world, artists are joyous. Unpredictability is the life of their paintings, their music, their novels. They delight in events not forecasted, happenings without explanation, retrospective.
As long as God does not intervene in the contemporary universe in such a way as to violate physical laws, science has no way of knowing whether God exists or not. The belief or disbelief in such a Being is therefore a matter of faith.
One cannot walk down an avenue, converse with a friend, enter a building, browse beneath the sandstone arches of an old arcade without meeting an instrument of time. Time is visible in all places. Clock towers, wristwatches, church bells divide years into months, months into days, days into hours, hours into seconds, each increment of time marching after the other in perfect succession. And beyond any particular clock, a vast scaffold of time, stretching across the universe, lays down the law of time equally for all.
Everyone shares the same fate.
In our constant search for meaning in this baffling and temporary existence, trapped as we are within our three pounds of neurons, it is sometimes hard to tell what is real. We often invent what isn't there. Or ignore what is. We try to impose order, both in our minds and in our conceptions of external reality. We try to connect. We try to find truth. We dream and we hope. And underneath all of these strivings, we are haunted by the suspicion that what we see and understand of the world is only a tiny piece of the whole.
In this acausal world, scientists are helpless. Their predictions become postdictions- Their equations become justifications, their logic, illogic. Scientists turn reckless and mutter like gamblers who cannot stop betting. Scientists are buffoons, not because they are rational but because the cosmos is irrational. Or perhaps it is not because the cosmos is irrational but because they are rational. Who can say which, in an acausal world?
The world is moving faster and faster, but where are we going?
The tragedy of this world is that no one is happy, whether stuck in atime of pain or of joy. The tragedy of this world is that everyone is alone. For a life in the past cannot be shared with the present. Each person who gets stuck in time gets stuck alone.
Faith is the ability to honor stillness at some moments, and at others to ride the passion and exuberance.
A person who cannot imagine the future is a person who cannot contemplate the results of his actions. Some are thus paralyzed into inaction.
Where are the one billion people who lived and breathed in the year 1800, only two short centuries ago?
The tragedy of this world is that no one is happy, whether stuck in a time of pain or joy.
For me, spirituality includes the belief in things larger than ourselves, an appreciation of nature and beauty, a sensitivity to the world, a feeling of shared connection with other living things, a desire to help people less fortunate than ourselves. All of these things can occur with or without God. I do not believe in the existence of God, but I consider myself a spiritual person in the manner I have just described. I call myself a spiritual atheist. I would imagine that many people are spiritual atheists.
The history of science can be viewed as the recasting of phenomena that were once thought to be accidents as phenomena that can be understood in terms of fundamental causes and principles.
The urge to discover, to invent, to know the unknown, seems so deeply human that we cannot imagine our history without it.
As human beings, don't we need questions without answers as well as questions with answers, questions that we might someday answer and questions that we can never answer?
Most people have learned to live in the moment. The argument goes that if the past has uncertain effect on the present, there is no need to dwell on the past. And if the present has little effect on the future, present actions need not be weighed for their consequence. Rather, each act is an island in time, to be judged on its own. ... It is a world of impulse. It is a world of sincerity. It is a world in which every word spoken speaks just to that moment, every glance given has only one meaning.
Some say it is best not to go near the center of time. Life is a vessel of sadness, but is noble to live life and without time there is no life. Others disagree. They would rather have an eternity of contentment, even if that eternity were fixed and frozen, like a butterfly mounted in a case.
We've lost our way, we have lost our centeredness. We don't have the time, literally, to think during the day. To listen to ourselves think. To think about where we are going, who we are, what's important. I would bet most people don't have thirty minutes in a day where they can just sit down and think. Or maybe they don't have to be sitting, they can be walking.
A world in which time is absolute is a world of consolation. For while the movements of people are unpredictable, the movement of time is predictable. While people can be doubted, time cannot be doubted. While people brood, time skips ahead without looking back. In the coffee houses, in the government buildings, in boats of Lake Geneva, people look at their watches and take refuge in time. Each person knows that somewhere is recorded the moment she was born, the moment she took her first step, the moment of her first passion, the moment she said goodbye to her parents.
-But rational thoughts lead only to rational thoughts, whereas irrational thoughts lead to new experiences.
Science is an intellectual journey, and to me, it's not the destination, it's the journeyto get there. It's a way of thinking and it's an intellectual curiosity, a desire to know how the world works, and to know what the fundamental principles of the world are, and to know our place in it. I think once we stop asking questions like "what is the age of the universe," or "how are the instructions of DNA carried out on a microscopic level," once we stop asking questions like that, we're dead.
The relationship between science and the humanities is two-way. Science changes our view of the world and our place in it. In the other direction, the humanities provide the store of ideas and images and language available to us in understanding the world. The exploding star of A.D. 1054, the Crab Nebula, was sighted and documented by the Chinese, but nowhere mentioned in the West, where the Aristotelian notion of the immortality of stars still held sway. We often do not see what we do not expect to see.
A life is a moment in season. A life is one snowfall. A life is one autumn day. A life is the delicate, rapid edge of a closing door's shadow. A life is a brief movement of arms and of legs.
If a person holds no ambitions in this world, he suffers unknowingly. If a person holds ambitions, he suffers knowingly, but very slowly.
Unconditional love. That’s what he wants to give her and what he wants from her. People should give without wanting anything in return. All other giving is selfish. But he is being selfish a little, isn’t he, by wanting her to love him in return? He hopes that she loves him in return. Is it possible for a person to love without wanting love back? Is anything so pure? Or is love, by its nature, a reciprocity, like oceans and clouds, an evaporating of seawater and a replenishing of rain?
It is a world of impulse. It is a world of sincerity. It is a world in which every word spoken speaks just to that moment, every glance given has only one meaning, each touch has no past or no future, each kiss is a kiss of immediacy.
