Famous Alan Lightman Quotes

“At the present time... we certainly do not know all the laws of nature, and it is a good bet that most of our current formulations of those laws will be revised in the future. Yet the great majority of scientists believe that a complete and final set of laws governing all physical phenomena exists, and that we are making continual progress toward discovery of those laws.”

“But why are we attracted to symmetry? Why do we human beings delight in seeing perfectly round planets through the lens of a telescope and six-sided snowflakes on a cold winter day? The answer must be partly psychological. I would claim that symmetry represents order, and we crave order in this strange universe we find ourselves in. The search for symmetry, and the emotional pleasure we derive when we find it, must help us make sense of the the seasons and the reliability of friendships. Symmetry is also economy. Symmetry is simplicity.”

“the architecture of our brains was born from the same trial and error, the same energy principles, the same pure mathematics that happen in flowers and jellyfish and Higgs particles. Viewed in this way, our human aesthetic is necessarily the aesthetic of nature. Viewed in this way, it is nonsensical to ask why we find nature beautiful. Beauty and symmetry and minimum principles are not qualities we ascribe to the cosmos and then marvel at in their perfection. They are simply what is, just like the particular arrangement of atoms that make up our minds. We are not observers on the outside looking in. We are on the inside too.”

“The deep question is: Why does nature embody so much symmetry? We do not know the full answer to this question. However, we have some partial answers. Symmetry leads to economy, and nature, like human beings, seems to prefer economy. If we think of nature as a vast ongoing experiment, constantly trying out different possibilities of design, then those designs that cost the least energy or that require the fewest different parts to come together at the right time will take precedence, just as the principle of natural selection says that organisms with the best ability to survive will dominate over time. One physical principle that governs nature over and over is the “energy principle”: nature evolves to minimize energy.”

“Will these millions of children, for generations upon future generations, know that some of their atoms cycled through this woman? [...] Will they feel what she felt in her life, will their memories have flickering strokes of her memories, will they recall that moment long ago when she stood by the window, guilt ridden and confused, and watched as the tadr bird circled the cistern? No, it is not possible. [...] But I will let them have their own brief glimpse of the Void, just at that moment they pass from living to dead, from animate to inanimate, from consciousness to that which has no consciousness. For a moment, they will understand infinity.”

“Something else gets under your skin, keeps you working days and nights at the sacrifice of your sleeping and eating and attention to your family and friends, something beyond the love of puzzle solving. And that other force is the anticipation of understanding something about the world that no one has ever understood before you. Einstein wrote that when he first realized that gravity was equivalent to acceleration -- an idea that would underlie his new theory of gravity -- it was the "happiest thought of my life." On projects of far smaller weight, I have experienced that pleasure of discovering something new. It is an exquisite sensation, a feeling of power, a rush of the blood, a sense of living forever. To be the first vessel to hold this new thing. All of the scientists I've known have at least one more quality in common: they do what they do because they love it, and because they cannot imagine doing anything else. In a sense, this is the real reason a scientist does science. Because the scientist must. Such a compulsion is both blessing and burden. A blessing because the creative life, in any endeavor, is a gift filled with beauty and not given to everyone, a burden because the call is unrelenting and can drown out the rest of life. This mixed blessing and burden must be why the astrophysicist Chandrasekhar continued working until his mid-80's, why a visitor to Einstein's apartment in Bern found the young physicist rocking his infant with one hand while doing mathematical calculations with the other. This mixed blessing and burden must have been the "sweet hell" that Walt Whitman referred to when he realized at a young age that he was destined to be a poet. "Never more," he wrote, "shall I escape.”

“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.”

“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.”

“That has been the great achievement of our age: to so thoroughly flood the planet with megabits that every image and fact has become a digitized disembodied nothingness. With magnificent determination, our species has advanced from Stone Age to Industrial Revolution to Digital Emptiness. We've become weightless, in the bad sense of the word.”

“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.”

“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 book is finished by the reader. A good novel should invite the reader in and let the reader participate in the creative experience and bring their own life experiences to it, interpret with their own individual life experiences. Every reader gets something different from a book and every reader, in a sense, completes it in a different way.”

“I think that the scienti?c way of looking at the world, and the humanistic way of looking at the world are complementary. There are important differences which should be preserved, and in trying to do away with those differences we would lose something the same way as if we tried to make all religions one religion or all races one race. There is a cultural diversity that's very valuable, and it's valuable to have different ways of looking at the world.”

“Don't you feel something magical when you're in love?... I do, I certainly do ... but I think that feeling of magic is a hardwired psychological response. It's a chemical thing in the brain. It's a flow of chemicals and electrical currents, and it developed over millions of years in the process of evolution to aid in the procreation of the species.”

“When the first mechanical clocks were invented, marking off time in crisp, regular intervals, it must have surprised people to discover that time flowed outside their own mental and physiological processes. Body time flows at its own variable rate, oblivious to the most precise hydrogen master clocks in the laboratory. In fact, the human body contains its own exquisite time-pieces, all with their separate rhythms. There are the alpha waves in the brain; another clock is the heart. And all the while tick the mysterious, ruthless clocks that regulate aging.”

“Nature is purposeless. Nature simply is. We may find nature beautiful or terrible, but those feelings are human constructions. Such utter and complete mindlessness is hard for us to accept. We feel such a strong connection to nature. But the relationship between nature and us is one-sided. There is no reciprocity. There is no mind on the other side of the wall.”

“I have no opposition at all to technology. I think technology is a wonderful thing that has to be used thoughtfully, and we can't just assume that every bit of new technology improvesthe quality of life; it's really in how the technology is used. What I am very disturbed about is this trend of everything happening faster and faster and faster and there being more and more general noise in the world, and less and less time for quiet reflection on who we are, and where we're going.”

“Although technology is proceeding at a dizzying pace, I believe that the human mind will always have control of itself. And since the human mind has a degree of infinity and imagination unlikely to be matched by a machine for a very, very long time, I don't think that we will become the machines of the machines.”

“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.”
