“The capacity to blunder slightly is the real marvel of DNA. Without this special attribute, we would still be anaerobic bacteria and there would be no music.”
― Lewis Thomas, The Lives of a Cell

“The greatest of all the accomplishments of 20th century science has been the discovery of human ignorance”
― Lewis Thomas

“Statistically, the probability of any one of us being here is so small that you'd think the mere fact of existing would keep us all in a contented dazzlement of surprise. ”
― Lewis Thomas

“I am a member of a fragile species, still new to the earth, the youngest creatures of any scale, here only a few moments as evolutionary time is measured, a juvenile species, a child of a species. We are only tentatively set in place, error prone, at risk of fumbling, in real danger at the moment of leaving behind only a thin layer of of our fossils, radioactive at that.”
― Lewis Thomas, The Fragile Species

“Statistically, the probability of any one of us being here is so small that the mere fact of our existence should keep us all in a state of contented dazzlement.”
― Lewis Thomas

“We are, perhaps uniquely among the earth’s creatures, the worrying animal. We worry away our lives, fearing the future, discontent with the present, unable to take the idea of dying, unable to sit still.”
― Lewis Thomas

“If we had better hearing, and could discern the descants of sea birds, the rhythmic tympani of schools of mollusks, or even the distant harmonics of midges hanging over meadows in the sun, the combined sound might lift us off our feet.”
― Lewis Thomas, The Lives of a Cell: Notes of a Biology Watcher

“The future is too interesting and dangerous to be entrusted to any predictable, reliable agency. We need all the fallibility we can get. Most of all, we need to preserve the absolute unpredictability and total improbability of our connected minds.”
― Lewis Thomas, The Lives of a Cell: Notes of a Biology Watcher

“The great thing about human language is that it prevents us from sticking to the matter at hand.”
― Lewis Thomas

“It is in our genes to understand the universe if we can, to keep trying even if we cannot, and to be enchanted by the act of learning all the way.”
― Lewis Thomas

“it is illusion to think that there is anything fragile about the life of the earth; surely this is the toughest membrane imaginable in the universe, opaque to probability, impermeable to death. We are the delicate part, transient and vulnerable as cilia. Nor is it a new thing for Man to invent an existence that he imagines to be above the rest of life; this has been his most consistent intellectual exertion down the millennia. As illusion, it has never worked out to his satisfaction in the past, any more than it does today.”
― Lewis Thomas, The Lives of a Cell: Notes of a Biology Watcher

“The oldest, easiest to swallow idea was that the earth was man's personal property, a combination of garden, zoo, bank vault, and energy source, placed at our disposal to be consumed, ornamented, or pulled apart as we wished.”
― Lewis Thomas, The Lives of a Cell: Notes of a Biology Watcher

“My mitochondria comprise a very large proportion of me. I cannot do the calculation, but I suppose there is almost as much of them in sheer dry bulk as there is the rest of me. Looked at in this way, I could be taken for a very large, motile colony of respiring bacteria, operating a complex system of nuclei, microtubules, and neurons for the pleasure and sustenance of their families, and running, at the moment, a typewriter.”
― Lewis Thomas, The Lives of a Cell: Notes of a Biology Watcher

“The greatest single achievement of nature to date was surely the invention of the molecule DNA.”
― Lewis Thomas

“A solitary ant, afield, cannot be considered to have much of anything on his mind; indeed, with only a few neurons strung together by fibers, he can’t be imagined to have a mind at all, much less a thought. He is more like a ganglion on legs. Four ants together, or ten, encircling a dead moth on a path, begin to look more like an idea. They fumble and shove, gradually moving the food toward the Hill, but as though by blind chance. It is only when you watch the dense mass of thousands of ants, crowded together around the Hill, blackening the ground, that you begin to see the whole beast, and now you observe it thinking, planning, calculating. It is an intelligence, a kind of live computer, with crawling bits for its wits.”

“Worrying is the most natural and spontaneous of all human functions. It is time to acknowledge this, perhaps even to learn to do it better.”
― Lewis Thomas, The Medusa and the Snail: More Notes of a Biology Watcher

“The uniformity of the earth's life, more astonishing than its diversity, is accountable by the high probability that we derived, originally, from some single cell, fertilized in a bolt of lightning as the earth cooled. It is from the progeny of this parent cell that we take our looks; we still share genes around, and the resemblance of the enzymes of grasses to those of whales is a family resemblance.”
― Lewis Thomas, The Lives of a Cell: Notes of a Biology Watcher

“Nature abhors a long silence.”
― Lewis Thomas, The Lives of a Cell: Notes of a Biology Watcher

“It is not a simple life to be a single cell, although I have no right to say so, having been a single cell so long ago myself that I have no memory at all of that stage in my life.”
― Lewis Thomas, The Youngest Science

“Have you noticed how often it happens that a really good idea -- the kind of idea that looks, as it approaches, like the explanation for everything about everything -- tends to hover near at hand when you are thinking hard about something quite different? There you are, halfway into a taxi, thinking about the condition of the cartilage in the right knee joint, and suddenly, with a whirring sound, in flies a new notion looking for a place to light. You'd better be sure you have a few bare spots, denuded of anything like thought, ready for its perching, or it will fly away into the dark.”
― Lewis Thomas, The Youngest Science

“Altruism, a jargon word for what used to be called love, is worse than weakness, it is sin, a violation of nature. Be seperate. Do not be a social animal.”
― Lewis Thomas

“Animals have genes for altruism, and those genes have been selected in the evolution of many creatures because of the advantage they confer for the continuing survival of the species.”
― Lewis Thomas, Late Night Thoughts on Listening to Mahler's Ninth Symphony

“Goldfish in a glass bowl are harmless to the human mind, maybe even helpful to minds casting about for something, anything, to think about. But goldfish let loose, propagating themselves, worst of all surviving in what has to be a sessile eddy of the East River, somehow threaten us all. We do not like to think that life is possible under some conditions, especially the conditions of a Manhattan pond. There are four abandoned ties, any number of broken beer bottles, fourteen shoes and a single sneaker, and a visible layer, all over the surface, of that grayish-green film that settles on all New York surfaces. The mud at the banks of the pond is not proper country mud but reconstituted Manhattan landfill, ancient garbage, fossilized coffee grounds and grapefruit rind, the defecation of a city. For goldfish to be swimming in such water, streaking back and forth mysteriously in small schools, feeding, obviously feeding, looking as healthy and well-off as goldfish in the costliest kind of window-box aquarium, means something is wrong with our standards. It is, in some deep sense beyond words, insulting.”

“As evolutionary time is measured, we have only just turned up and have hardly had time to catch breath, still marveling at our thumbs, still learning to use the brand-new gift of language. Being so young, we can be excused all sorts of folly and can permit ourselves the hope that someday, as a species, we will begin to grow up.”
― Lewis Thomas

“It is hard to feel affection for something as totally impersonal as the atmosphere, and yet there it is, as much a part and product of life as wine and bread. Taken all in al, the sky is a miraculous achievement. It works, and for what it is designed to accomplish it is as infallible as anything in nature. I doubt whether any of us could think of a way to improve on it, beyond maybe shifting a local cloud from here to there on occasion. The word 'chance' does not serve to account well for structures of such magnificence...
We should credit it for what it is: for sheer size and perfection of function, it is far and away the grandest product of collaboration in all of nature.
It breathes for us, and it does another thing for our pleasure. Each day, millions of meteorites fall against the outer limits of the membrane and are burned to nothing by the friction. Without this shelter, our surface would long since have become the pounded powder of the moon. Even though our receptors are not sensitive enough to hear it, there is comfort in knowing the sound is there overhead, like the random noise of rain on the roof at night.”
― Lewis Thomas, The Lives of a Cell: Notes of a Biology Watcher

“It is in our collective behavior that we are the most mysterious. We won't be able to construct machines like ourselves until we've understood this, and we're not even close. All we know is the phenomenon: we spend our time sending messages to each other, talking and trying to listen at the same time, exchanging information. This seems to be our most urgent biological function; it is what we do with our lives. By the time we reach the end, each of us has taken in a staggering store, enough to exhaust any computer, much of it incomprehensible, and we generally manage to put out even more than we take in. Information is our source of energy; we are driven by it. It has become a tremendous enterprise, a kind of energy system on its own. All 3 billion of us are being connected by telephones, radios, television sets, airplanes, satellites, harangues on public-address systems, newspapers, magazines, leaflets dropped from great heights, words got in edgewise. We are becoming a grid, a circuitry around the earth.”

“Not all social animals are social with the same degree of commitment. In some species, the members are so tied to each other and interdependent as to seem the loosely conjoined cells of a tissue. The social insects are like this; they move, and live all their lives, in a mass; a beehive is a spherical animal. In other species, less compulsively social, the members make their homes together, pool resources, travel in packs or schools, and share the food, but any single one can survive solitary, detached from the rest. Others are social only in the sense of being more or less congenial, meeting from time to time in committees, using social gatherings as ad hoc occasions for feeding and breeding. Some animals simply nod at each other in passing, never reaching even a first-name relationship.”

“Perhaps it is in this respect that language differs most sharply from other biologic systems for communication. Ambiguity seems to be an essential, indispensable element for the transfer of information from one place to another by words, where matters of real importance are concerned. It is often necessary, for meaning to come through, that there be an almost vague sense of strangeness and askewness. Speechless animals and cells cannot do this. The specifically locked-on antigen at the surface of a lymphocyte does not send the cell off in search of something totally different; when a bee is tracking sugar by polarized light, observing the sun as though consulting his watch, he does not veer away to discover an unimaginable marvel of a flower. Only the human mind is designed to work in this way, programmed to drift away in the presence of locked-on information, straying from each point in a hunt for a better, different point.
If it were not for the capacity for ambiguity, for the sensing of strangeness, the words in all languages provide, we would have no way of recognizing the layers of counterpoint in meaning, and we might be spending all our time sitting on stone fences, staring into the sun. To be sure, we would always have had some everyday use to make of the alphabet, and we might have reached the same capacity for small talk, but it is unlikely that we would have been able to evolve from words to Bach. The great thing about human language is that it prevents us from sticking to the matter at hand.”
