Music is the effort we make to explain to ourselves how our brains work. We listen to Bach transfixed because this is listening to a human mind.

Lewis Thomas
Worrying is the most natural and spontaneous of all human functions.

Lewis Thomas
Mistakes are at the very base of human thought, embedded there, feeding the structure like root nodules. If we were not provided with the knack of being wrong, we could never get anything useful done.

Lewis Thomas
There is within medicine, somewhere beneath the pessimism and discouragement resulting from the disarray of the health-care system and its stupendous cost, an undercurrent of almost outrageous optimism about what may lie ahead for the treatment of human disease if we can only keep learning.

Lewis Thomas
The human mind is not meant to be governed, certainly not by any book of rules yet written; it is supposed to run itself, and we are obliged to follow it along, trying to keep up with it as best we can.

Lewis Thomas
The essential wildness of science as a manifestation of human behavior is not generally perceived. As we extract new things of value from it, we also keep discovering parts of the activity that seem in need of better control, more efficiency, less unpredictability.

Lewis Thomas
In evolutionary terms, we have only just arrived.... We cannot trace ourselves back more than a few thousand years before losing sight of what we think of as the real human article... And [we are] vulnerable, error-prone still, at risk of leaving only a thin layer of radioactive fossils.

Lewis Thomas
It is a distortion, with something profoundly disloyal about it, to picture the human being as a teetering, fallible contraption, always needing, watching and patching, always on the verge of flapping to pieces.

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

Lewis Thomas
We still think of human disease as the work of an organized, modernized kind of demonology, in which the bacteria are the most visible and centrally placed of our adversaries. We assume that they must somehow relish what they do.

Lewis Thomas
I do not agree with this century's fashion of running down the human species as a failed try, a doomed sport. At our worst, we may be going through the early stages of adolescence, and everyone remembers what that is like.

Lewis Thomas
The human brain is the most public organ on the face of the earth, open to everything, sending out messages to everything. To be sure, it is hidden away in bone and conducts internal affairs in secrecy, but virtually all the business is the direct result of thinking that has already occurred in other minds.

Lewis Thomas
The need to make music, and to listen to it, is universally expressed by human beings. I cannot imagine, even in our most primitive times, the emergence of talented painters to make cave paintings without there having been, near at hand, equally creative people making song. It is, like speech, a dominant aspect of human biology.

Lewis Thomas
The great secret, known to internists and learned early in marriage by internist's wives, but still hidden from the general public, is that most things get better by themselves. Most things, in fact, are better by morning. Obviously, it is a great time-saver and money-saver for the physician's family that anxiety about disease is not handled as though it were the disease itself; there is perhaps greater willingness to accept anxiety as a natural, often transient, phenomenon. And certainly there is much less ambition to deploy the full technology of medicine as a corrective for the human condition.

Lewis Thomas
As a people we have become obsessed with Health. There is something fundamentally, radically unhealthy about all this. We do not seem to be seeking more exuberance in living as much as staving off failure, putting off dying. We have lost all confidence in the human body.

Lewis Thomas
The cloning of humans is on most of the lists of things to worry about from Science, along with behavior control, genetic engineering, transplanted heads, computer poetry and the unrestrained growth of plastic flowers.

Lewis Thomas
Ants are so much like human beings as to be an embarrassment. They farm fungi, raise aphids as livestock, launch armies into war, use chemical sprays to alarm and confuse enemies, capture slaves, engage in child labour, exchange information ceaselessly. They do everything but watch television.

Lewis Thomas
I am entitled to say, if I like, that awareness exists in all the individual creatures on the planet-worms, sea urchins, gnats, whales, subhuman primates, superprimate humans, the lot. I can say this because we do not know what we are talking about: consciousness is so much a total mystery for our own species that we cannot begin to guess about its existence in others.

Lewis Thomas
We pass the word around; we ponder how the case is put by different people, we read the poetry; we meditate over the literature; we play the music; we change our minds; we reach an understanding. Society evolves this way, not by shouting each other down, but by the unique capacity of unique, individual human beings to comprehend each other.

Lewis Thomas
Be individuals, solitary and selfish, is the message. Altruism, a jargon word for what used to be called love, is worse than weakness, it is sin, a violation of nature. Be separate. Do not be a social animal. But this is a hard argument to make convincingly when you have to depend on language to make it. You have to print out leaflets or publish books and get them bought and sent around, you have to turn up on television and catch the attention of millions of other human beings all at once, and then you have to say to all of them, all at once, all collected and paying attention: be solitary; do not depend on each other. You can't do this and keep a straight face.

Lewis Thomas
The gift of language is the single human trait that marks us all genetically, setting us apart from the rest of life.

Lewis Thomas
The only solid piece of scientific truth about which I feel totally confident is that we are profoundly ignorant about nature... It is this sudden confrontation with the depth and scope of ignorance that represents the most significant contribution of twentieth-century science to the human intellect.

Lewis Thomas
Cats are a standing rebuke to behavioral scientists wanting to know how the minds of animals work. The mind of a cat is an inscrutable mystery, beyond human reach, the least human of all creatures and at the same time, as any cat owner will attest, the most intelligent.

Lewis Thomas
We are at our human finest, dancing with our minds, when there are more choices than two. Sometimes there are ten, even twenty different ways to go, all but one bound to be wrong, and the richness of the selection in such situations can lift us onto totally new ground.

Lewis Thomas
I can think of a few microorganisms, possibly the tubercle bacillus, the syphilis spirochete, the malarial parasite, and a few others, that have a selective advantage in their ability to infect human beings, but there is nothing to be gained, in an evolutionary sense, by the capacity to cause illness or death. Pathogenicity may be something of a disadvantage for most microbes, carrying lethal risks far more frightening to them than to us. The man who catches a meningococcus is in considerably less danger for his life, even without chemotherapy, than meningococci with the bad luck to catch a man.
