Scientific Method Quotes

In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.

I am convinced that the act of thinking logically cannot possibly be natural to the human mind. If it were, then mathematics would be everybody's easiest course at school and our species would not have taken several millennia to figure out the scientific method.

Everything must be taken into account. If the fact will not fit the theory---let the theory go.

The real purpose of the scientific method is to make sure nature hasn’t misled you into thinking you know something you actually don’t know.

If you've got the truth you can demonstrate it. Talking doesn't prove it.

Science, my boy, is made up of mistakes, but they are mistakes which it is useful to make, because they lead little by little to the truth.

Now, the invention of the scientific method and science is, I'm sure we'll all agree, the most powerful intellectual idea, the most powerful framework for thinking and investigating and understanding and challenging the world around us that there is, and that it rests on the premise that any idea is there to be attacked and if it withstands the attack then it lives to fight another day and if it doesn't withstand the attack then down it goes. Religion doesn't seem to work like that; it has certain ideas at the heart of it which we call sacred or holy or whatever. That's an idea we're so familiar with, whether we subscribe to it or not, that it's kind of odd to think what it actually means, because really what it means is 'Here is an idea or a notion that you're not allowed to say anything bad about; you're just not. Why not? - because you're not!

If we can't think for ourselves, if we're unwilling to question authority, then we're just putty in the hands of those in power. But if the citizens are educated and form their own opinions, then those in power work for us. In every country, we should be teaching our children the scientific method and the reasons for a Bill of Rights. With it comes a certain decency, humility and community spirit. In the demon-haunted world that we inhabit by virtue of being human, this may be all that stands between us and the enveloping darkness.

It takes a fearless, unflinching love and deep humility to accept the universe as it is. The most effective way he knew to accomplish that, the most powerful tool at his disposal, was the scientific method, which over time winnows out deception. It can't give you absolute truth because science is a permanent revolution, always subject to revision, but it can give you successive approximations of reality.

There’s nothing quite as frightening as someone who knows they are right.

When the number of factors coming into play in a phenomenological complex is too large scientific method in most cases fails. One need only think of the weather, in which case the prediction even for a few days ahead is impossible.

When we speak of man, we have a conception of humanity as a whole, and before applying scientific methods to the investigation of his movement we must accept this as a physical fact. But can anyone doubt to-day that all the millions of individuals and all the innumerable types and characters constitute an entity, a unit? Though free to think and act, we are held together, like the stars in the firmament, with ties inseparable. These ties cannot be seen, but we can feel them. I cut myself in the finger, and it pains me: this finger is a part of me. I see a friend hurt, and it hurts me, too: my friend and I are one. And now I see stricken down an enemy, a lump of matter which, of all the lumps of matter in the universe, I care least for, and it still grieves me. Does this not prove that each of us is only part of a whole? For ages this idea has been proclaimed in the consummately wise teachings of religion, probably not alone as a means of insuring peace and harmony among men, but as a deeply founded truth. The Buddhist expresses it in one way, the Christian in another, but both say the same: We are all one. Metaphysical proofs are, however, not the only ones which we are able to bring forth in support of this idea. Science, too, recognizes this connectedness of separate individuals, though not quite in the same sense as it admits that the suns, planets, and moons of a constellation are one body, and there can be no doubt that it will be experimentally confirmed in times to come, when our means and methods for investigating psychical and other states and phenomena shall have been brought to great perfection. Still more: this one human being lives on and on. The individual is ephemeral, races and nations come and pass away, but man remains. Therein lies the profound difference between the individual and the whole.

I don't have a method. All I do is read a lot, think a lot, and rewrite constantly. It's not a scientific thing.

But the reason I call myself by my childhood name is to remind myself that a scientist must also be absolutely like a child. If he sees a thing, he must say that he sees it, whether it was what he thought he was going to see or not. See first, think later, then test. But always see first. Otherwise you will only see what you were expecting.

Scientific method, hell! No wonder the Galaxy was going to pot.

The plural of anecdote is not data.

Should philosophy guide experiments, or should experiments guide philosophy?

The scientific method is nothing more than a system of rules to keep us from lying to each other.

Science, at its core, is simply a method of practical logic that tests hypotheses against experience. Scientism, by contrast, is the worldview and value system that insists that the questions the scientific method can answer are the most important questions human beings can ask, and that the picture of the world yielded by science is a better approximation to reality than any other.

We may not yet know the right way to go, but we should at least stop going in the wrong direction.

This is one of the most important lessons of the scientific method: if you cannot fail, you cannot learn.

Truth has nothing to do with the conclusion, and everything to do with the methodology.

Think of how many religions attempt to validate themselves with prophecy. Think of how many people rely on these prophecies, however vague, however unfulfilled, to support or prop up their beliefs. Yet has there ever been a religion with the prophetic accuracy and reliability of science? ... No other human institution comes close.

Just because an idea is true doesn't mean it can be proved. And just because an idea can be proved doesn't mean it's true.

There is no "black mind" or "white mind", no "white male of knowing", there is only one truth, and we find it through the scientific method.

Scientific method seeks to understand things as they are, while alchemy seeks to bring about a desired state of affairs. To put it another way, the primary objective of science is truth, - that of alchemy, operational success.

It is not the victory of science that distinguishes our nineteenth century, but the victory of scientific method over science.

The scientific method," Thomas Henry Huxley once wrote, "is nothing but the normal working of the human mind." That is to say, when the mind is working; that is to say further, when it is engaged in corrrecting its mistakes. Taking this point of view, we may conclude that science is not physics, biology, or chemistry--is not even a "subject"--but a moral imperative drawn from a larger narrative whose purpose is to give perspective, balance, and humility to learning.

but this is the real objection to that torrent of modern talk about treating crime as disease, about making prison merely a hygienic environment like a hospital, of healing sin by slow scientific methods. The fallacy of the whole thing is that evil is a matter of active choice whereas disease is not.

So my antagonist said, "Is it impossible that there are flying saucers? Can you prove that it's impossible?" "No", I said, "I can't prove it's impossible. It's just very unlikely". At that he said, "You are very unscientific. If you can't prove it impossible then how can you say that it's unlikely?" But that is the way that is scientific. It is scientific only to say what is more likely and what less likely, and not to be proving all the time the possible and impossible.

The whole [scientific] process resembles biological evolution. A problem is like an ecological niche, and a theory is like a gene or a species which is being tested for viability in that niche.

I would remind you to notice where the claim of consensus is invoked. Consensus is invoked only in situations where the science is not solid enough. Nobody says the consensus of scientists agrees that E=mc2. Nobody says the consensus is that the sun is 93 million miles away. It would never occur to anyone to speak that way.

The TV scientist who mutters sadly, "The experiment is a failure; we have failed to achieve what we had hoped for," is suffering mainly from a bad script writer. An experiment is never a failure solely because it fails to achieve predicted results. An experiment is a failure only when it also fails adequately to test the hypothesis in question, when the data it produces don't prove anything one way or another.

I want to pause here and talk about this notion of consensus, and the rise of what has been called consensus science. I regard consensus science as an extremely pernicious development that ought to be stopped cold in its tracks. Historically, the claim of consensus has been the first refuge of scoundrels; it is a way to avoid debate by claiming that the matter is already settled. Whenever you hear the consensus of scientists agrees on something or other, reach for your wallet, because you're being had. Let's be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus. There is no such thing as consensus science. If it's consensus, it isn't science. If it's science, it isn't consensus. Period.

There are two objectionable types of believers: those who believe the far-fetched, and those who believe that 'belief' must be discarded and replaced by the 'scientific method.' Between these two extremes there is enough scope for believing the reasonable and reasoning on sound beliefs.

His lack of reverence for authority and his willingness to challenge received wisdom would lead him to craft an empirical approach for understanding nature that foreshadowed the scientific method developed more than a century later by Bacon and Galileo. His method was rooted in experiment, curiosity, and the ability to marvel at phenomena that the rest of us rarely pause to ponder after we’ve outgrown our wonder years.

She was a triumph over ugliness, so often more beguiling than real beauty, if only because it contains paradox. In this case, as opposed to the scrupulous method of good taste and scientific grooming, the trick had been worked by exaggerating defects; she'd made them ornamental by admitting them boldly.

Such prizes and punishments are, if I may be allowed the expression, the bench of the soul, the instrument of slavery for the spirit.

We must conduct research and then accept the results. If they don't stand up to experimentation, Buddha's own words must be rejected.

The peculiar predicament of the present-day self surely came to pass as a consequence of the disappointment of the high expectations of the self as it entered the age of science and technology. Dazzled by the overwhelming credentials of science, the beauty and elegance of the scientific method, the triumph of modern medicine over physical ailments, and the technological transformation of the very world itself, the self finds itself in the end disappointed by the failure of science and technique in those very sectors of life which had been its main source of ordinary satisfaction in past ages. As John Cheever said, the main emotion of the adult Northeastern American who has had all the advantages of wealth, education, and culture is disappointment. Work is disappointing. In spite of all the talk about making work more creative and self-fulfilling, most people hate their jobs, and with good reason. Most work in modern technological societies is intolerably dull and repetitive. Marriage and family life are disappointing. Even among defenders of traditional family values, e.g., Christians and Jews, a certain dreariness must be inferred, if only from the average time of TV viewing. Dreary as TV is, it is evidently not as dreary as Mom talking to Dad or the kids talking to either. School is disappointing. If science is exciting and art is exhilarating, the schools and universities have achieved the not inconsiderable feat of rendering both dull. As every scientist and poet knows, one discovers both vocations in spite of, not because of, school. It takes years to recover from the stupor of being taught Shakespeare in English Lit and Wheatstone's bridge in Physics. Politics is disappointing. Most young people turn their backs on politics, not because of the lack of excitement of politics as it is practiced, but because of the shallowness, venality, and image-making as these are perceived through the media--one of the technology's greatest achievements. The churches are disappointing, even for most believers. If Christ brings us new life, it is all the more remarkable that the church, the bearer of this good news, should be among the most dispirited institutions of the age. The alternatives to the institutional churches are even more grossly disappointing, from TV evangelists with their blown-dry hairdos to California cults led by prosperous gurus ignored in India but embraced in La Jolla. Social life is disappointing. The very franticness of attempts to reestablish community and festival, by partying, by groups, by club, by touristy Mardi Gras, is the best evidence of the loss of true community and festival and of the loneliness of self, stranded as it is as an unspeakable consciousness in a world from which it perceives itself as somehow estranged, stranded even within its own body, with which it sees no clear connection. But there remains the one unquestioned benefit of science: the longer and healthier life made possible by modern medicine, the shorter work-hours made possible by technology, hence what is perceived as the one certain reward of dreary life of home and the marketplace: recreation. Recreation and good physical health appear to be the only ambivalent benefits of the technological revolution.

She considered hypothesis 3 to be quite unlikely, since she didn’t feel the least bit psychopathic, but included it in the list out of respect for the scientific method.

Science, however, is never conducted as a popularity contest, but instead advances through testable, reproducible, and falsifiable theories.

For God to prove himself on demand, physically, would be a grave disappointment, and the strongest Christians should be considerably grateful that he chooses not to do so. The skeptic endlessly demands proof, yet God refuses to insult the true intelligence of man, the '6th sense', the chief quality, the acumen which distinguishes man from the rest of creation, faith.

If these out-of date beliefs are to be called myths, then myths can be produced by the same sorts of methods and held for the same sorts of reasons that now lead to scientific knowledge

Atheism may be defined as the mental attitude which unreservedly accepts the supremacy of reason and aims at establishing a lifestyle and ethical outlook verifiable by experience and the scientific method, independent of all arbitrary assumptions of authority and creeds.

Educators may bring upon themselves unnecessary travail by taking a tactless and unjustifiable position about the relation between scientific and religious narratives. We see this, of course, in the conflict concerning creation science. Some educators representing, as they think, the conscience of science act much like those legislators who in 1925 prohibited by law the teaching of evolution in Tennessee. In that case, anti-evolutionists were fearful that a scientific idea would undermine religious belief. Today, pro-evolutionists are fearful that a religious idea will undermine scientific belief. The former had insufficient confidence in religion; the latter insufficient confidence in science. The point is that profound but contradictory ideas may exist side by side, if they are constructed from different materials and methods and have different purposes. Each tells us something important about where we stand in the universe, and it is foolish to insist that they must despise each other.

The whole purpose of scientific method is to make valid distinctions between the false and the true in nature, to eliminate the subjective, unreal, imaginary elements from one’s work so as to obtain an objective, true picture of reality.

Facts do not fall in the face of discomfort.

We must trust to nothing but facts: These are presented to us by Nature, and cannot deceive. We ought, in every instance, to submit our reasoning to the test of experiment, and never to search for truth but by the natural road of experiment and observation.

Science is not about making predictions or performing experiments. Science is about explaining.

There are so many ways to account for negative outcomes that it is safer to doubt one’s methods before doubting one’s subjects.

With increasing distance, our knowledge fades, and fades rapidly. Eventually, we reach the dim boundary—the utmost limits of our telescopes. There, we measure shadows, and we search among ghostly errors of measurement for landmarks that are scarcely more substantial. The search will continue. Not until the empirical resources are exhausted, need we pass on to the dreamy realms of speculation.

The modern scientific method in which experiments form part of a structured system of hypothesis, experimentation, and analysis is as recent as the seventeenth century; the problem-solving technology of cooking goes back thousands of years.

The Scientific Method is a wonderful tool as long as you don't care which way the outcome turns; however, this process fails the second one's perception interferes with the interpretation of data. This is why I don’t take anything in life as an absolute…even if someone can “prove” it “scientifically.

Whereas a novice makes moves until he gets checkmated (proof), a Grand Master realizes 20 moves in advance that it’s futile to continue playing (conceptualizing).

If you’re doing an experiment, you should report everything that you think might make it invalid—not only what you think is right about it: other causes that could possibly explain your results; and things you thought of that you’ve eliminated by some other experiment, and how they worked—to make sure the other fellow can tell they have been eliminated.

Astronomers now find they have painted themselves into a corner because they have proven, by their own methods, that the world began abruptly in an act of creation to which you can trace the seeds of every star, every planet, every living thing in this cosmos and on the earth. And they have found that all this happened as a product of forces they cannot hope to discover. That there are what I or anyone would call supernatural forces at work is now, I think, a scientifically proven fact.

What we know here is very little, but what we are ignorant of is immense.

Look ... first and foremost, I'm a scientist. That means it's my responsibility to make observations and gather evidence before forming a hypothesis, not vice versa.

That goes a step too far, I think. Leonardo did not invent the scientific method, nor did Aristotle or Alhazen or Galileo or any Bacon. But his uncanny abilities to engage in the dialogue between experience and theory made him a prime example of how acute observations, fanatic curiosity, experimental testing, a willingness to question dogma, and the ability to discern patterns across disciplines can lead to great leaps in human understanding.

In Newspeak there is no word for ‘Science’. The empirical method of thought, on which all the scientific achievements of the past were founded, is opposed to the most fundamental principles of Ingsoc.

One reader of an early draft of this chapter complained at this point, saying that by treating the hypothesis of God as just one more scientific hypothesis, to be evaluated by the standards of science in particular and rational thought in general, Dawkins and I are ignoring the very widespread claim by believers in God that their faith is quite beyond reason, not a matter to which such mundane methods of testing applies. It is not just unsympathetic, he claimed, but strictly unwarranted for me simply to assume that the scientific method continues to apply with full force in this domain of truth. Very well, let's consider the objection. I doubt that the defender of religion will find it attractive, once we explore it carefully. The philosopher Ronaldo de Souza once memorably described philosophical theology as "intellectual tennis without a net," and I readily allow that I have indeed been assuming without comment or question up to now that the net of rational judgement was up. But we can lower it if you really want to. It's your serve. Whatever you serve, suppose I return service rudely as follows: "What you say implies that God is a ham sandwich wrapped in tin foil. That's not much of a God to worship!". If you then volley back, demanding to know how I can logically justify my claim that your serve has such a preposterous implication, I will reply: "oh, do you want the net up for my returns, but not for your serves? Either way the net stays up, or it stays down. If the net is down there are no rules and anybody can say anything, a mug's game if there ever was one. I have been giving you the benefit of the assumption that you would not waste your own time or mine by playing with the net down.

Every brilliant experiment, like every great work of art, starts with an act of imagination. Unfortunately, our current culture subscribes to a very narrow definition of truth. If something can’t be quantified and calculated, then it can’t be true. Because this strict scientific approach has explained so much, we assume that it can explain everything. But every method, even the experimental method, has limits. Take the human mind. Scientists describe our brain in terms of its physical details; they say we are nothing but a loom of electrical cells and synaptic spaces. What science forgets is that this isn’t how we experience the world. (We feel like the ghost, not like the machine.) It is ironic but true: the one reality science cannot reduce is the only reality we will ever know. This is why we need art. By expressing our actual experience, the artist reminds us that our science is incomplete, that no map of matter will ever explain the immateriality of our consciousness.

Traditional scientific method has always been at the very best, 20–20 hindsight. It’s good for seeing where you’ve been. It’s good for testing the truth of what you think you know, but it can’t tell you where you ought to go, unless where you ought to go is a continuation of where you were going in the past. Creativity, originality, inventiveness, intuition, imagination—“unstuckness,” in other words—are completely outside its domain.

It is debatable whether blind faith is truly faith at all. Faith is the perceptive gray area where scientific facts meet an individual's experiential truths - the extreme of the former is left feeling in the dark whereas the latter is caught blinded by the light. By proper scientific method, it is intellectually dishonest for me to declare the existence of God with utmost certainty, but to my individual spirit, I would be intellectually dishonest to deny the existence of God even for a second. This leaves the best of both worlds, as the believer is called to be able to give reasons for his faith, a deviation from mere fantasy.

The real purpose of the scientific method is to make sure Nature hasn't misled you into thinking you know something you don't actually know. There's not a mechanic or scientist or technician alive who hasn't suffered from that one so much that he's not instinctively on guard. That's the main reason why so much scientific and mechanical information sounds so dull and so cautious. If you get careless or go romanticizing scientific information, give it a flourish here and there, Nature will soon make a complete fool out of you. It does it often enough anyway even when you don't give it opportunities. One must be extremely careful and rigidly logical when dealing with Nature: one logical slip and an entire scientific edifice comes tumbling down. One false deduction about the machine and you can get hung up indefinitely.

Yes, I'm a materialist. I'm willing to be shown wrong, but that has not happened — yet. And I admit that the reason I'm unable to accept the claims of psychic, occult, and/or supernatural wonders is because I'm locked into a world-view that demands evidence rather than blind faith, a view that insists upon the replication of all experiments — particularly those that appear to show violations of a rational world — and a view which requires open examination of the methods used to carry out those experiments.

In a democracy scientific institutions, research programmes, and suggestions must therefore be subjected to public control, there must be a separation of state and science just as there is a separation between state and religious institutions, and science should be taught as one view among many and not as the one and only road to truth and reality.

How do we find words for describing levels of betrayal and emotional, physical, sexual and spiritual torture that fragment and destroy a child or cast and case traumatic shadows over the whole of adult life? We might, as a society, slowly find it possible to accept that one in four citizens are likely to have experience some form of emotional, psychical, sexual or spiritual abuse (McQueen, Itzin, Kennedy, Sinason, & Maxted, 2008), in itself a figure unimaginable and hidden twenty years ago. However, accepting the way a hurt and hurting parent or stranger re-enacts their disturbance with a vulnerable child or children remains far easier to digest than to consider the intellectually planned, scientific, methodical, procedures of organized child-abusing perpetrators-in other words, torture.

Lies propagate, that's what I'm saying. You've got to tell more lies to cover them up, lie about every fact that's connected to the first lie. And if you kept on lying, and you kept on trying to cover it up, sooner or later you'd even have to start lying about the general laws of thought. Like, someone is selling you some kind of alternative medicine that doesn't work, and any double-blind experimental study will confirm that it doesn't work. So if someone wants to go on defending the lie, they've got to get you to disbelieve in the experimental method. Like, the experimental method is just for merely scientific kinds of medicine, not amazing alternative medicine like theirs. Or a good and virtuous person should believe as strongly as they can, no matter what the evidence says. Or truth doesn't exist and there's no such thing as objective reality. A lot of common wisdom like that isn't just mistaken, it's anti-epistemology, it's systematically wrong. Every rule of rationality that tells you how to find the truth, there's someone out there who needs you to believe the opposite. If you once tell a lie, the truth is ever after your enemy; and there's a lot of people out there telling lies.

We all have an unscientific weakness for being always in the right, and this weakness seems to be particularly common among professional and amateur politicians. But the only way to apply something like scientific method in politics is to proceed on the assumption that there can be no political move which has no drawbacks, no undesirable consequences. To look out for these mistakes, to find them, to bring them into the open, to analyse them, and to learn from them, this is what a scientific politician as well as a political scientist must do. Scientific method in politics means that the great art of convincing ourselves that we have not made any mistakes, of ignoring them, of hiding them, and of blaming others from them, is replaced by the greater art of accepting the responsibility for them, of trying to learn from them, and of applying this knowledge so that we may avoid them in future.

For such people, the ruling gods are progress, science, and development. They imagine that we know so much more about the world than those people of olden times, because "we" have science. Of course, they themselves do not have science, they have simply heard and believed that scientific knowledge is real knowledge. They know little about the goals and methods of science, and nothing about the Islamic Intellectual tradition. They are blind imitators in intellectual issues, that is, on the level where they should be striving for their own understanding. What is worse, this is a selective imitation, since they only accept the authority of the "scientists" and the "experts", not that of the great Muslim thinkers of the past. If Einstein said it, it must be true, but if Al-Ghazali or Mulla Sadra said it, then it can't be true, because it isn't scientific.

The first is to embrace—as a matter of philosophy and public policy—the insights of science, in particular the fields that descend from the great Darwinian revolution that began only a matter of years after Snow’s death: genetics, evolutionary theory, environmental science. Our safety depends on being able to predict the evolutionary path that viruses and bacteria will take in the coming decades, just as safety in Snow’s day depended on the rational application of the scientific method to public-health matters. Superstition, then and now, is not just a threat to the truth. It’s also a threat to national security.

One method is to try asking the question "why" as many times as it takes to get to an emotion. Usually this will happen by the fifth “why.” This is a technique adapted from the Toyota Production System described by Taiichi Ohno as the “5 Whys Method.” Ohno wrote that it was "the basis of Toyota's scientific approach ... by repeating ‘why?’ five times, the nature of the problem as well as its solution becomes clear.

Details that could throw doubt on your interpretation must be given, if you know them. You must do the best you can—if you know anything at all wrong, or possibly wrong—to explain it. If you make a theory, for example, and advertise it, or put it out, then you must also put down all the facts that disagree with it, as well as those that agree with it. There is also a more subtle problem. When you have put a lot of ideas together to make an elaborate theory, you want to make sure, when explaining what it fits, that those things it fits are not just the things that gave you the idea for the theory; but that the finished theory makes something else come out right, in addition.

Orthodox Marxism, therefore, does not imply the uncritical acceptance of the results of Marx’s investigations. It is not the ‘belief’ in this or that thesis, nor the exegesis of a ‘sacred’ book. On the contrary, orthodoxy refers exclusively to method. It is the scientific conviction that dialectical materialism is the road to truth and that its methods can be developed, expanded and deepened only along the lines laid down by its founders. It is the conviction, moreover, that all attempts to surpass or ‘improve’ it have led and must lead to over-simplification, triviality and eclecticism.

Our willingness to accept scientific claims that are against common sense is the key to an understanding of the real struggle between science and the supernatural. We take the side of science in spite of the patent absurdity of some of its constructs, in spite of its failure to fulfill many of its extravagant promises of health and life, in spite of the tolerance of the scientific community for unsubstantiated just-so stories, because we have a prior commitment, a commitment to materialism. It is not that the methods and institutions of science somehow compel us to accept a material explanation of the phenomenal world, but, on the contrary, that we are forced by our a priori adherence to material causes to create an apparatus of investigation and a set of concepts that produce material explanations, no matter how counter-intuitive, no matter how mystifying to the uninitiated. Moreover, that materialism is absolute, for we cannot allow a Divine Foot in the door. [Billions and Billions of Demons - JANUARY 9, 1997 ISSUE]

We are indeed dealing with two entirely different approaches to reality and to solving problems — methods we will here call the rational method and the magical one. The rational approach works quite well in certain situations, such as mass production of goods, or in certain kinds of scientific measurements — but all in all the rational method, as it is understood and used, does not work as an overall approach to life, or in the solving of problems that involve subjective rather than objective measurements or calculations. The magical approach has far greater weight, if you use it and allow yourselves to operate in that fashion, for it has the weight of your basic natural orientation.

I believe that we must attack these things in which we do not believe. Not attack by the method of cutting off the heads of the people, but attack in the sense of discuss. I believe that we should demand that people try in their own minds to obtain for themselves a more consistent picture of their own world; that they not permit themselves the luxury of having their brain cut in four pieces or two pieces even, and on one side they believe this and on the other side they believe that, but never try to compare the two points of view. Because we have learned that, by trying to put the points of view that we have in our head together and comparing one to the other, we make some progress in understanding and in appreciating where we are and what we are. And I believe that science has remained irrelevant because we wait until somebody asks us questions or until we are invited to give a speech on Einstein’s theory to people who don’t understand Newtonian mechanics, but we never are invited to give an attack on faith healing, or on astrology — on what is the scientific view of astrology today.

One of the difficulties in raising public concern over the very severe threats of global warming is that 40 percent of the US population does not see why it is a problem, since Christ is returning in a few decades. About the same percentage believe that the world was created a few thousand years ago. If science conflicts with the Bible, so much the worse for science. It would be hard to find an analogue in other societies.

The scientist has a lot of experience with ignorance and doubt and uncertainty, and this experience is of very great importance, I think. When a scientist doesn’t know the answer to a problem, he is ignorant. When he has a hunch as to what the result is, he is uncertain. And when he is pretty damn sure of what the result is going to be, he is still in some doubt. We have found it of paramount importance that in order to progress, we must recognize our ignorance and leave room for doubt. Scientific knowledge is a body of statements of varying degrees of certainty — some most unsure, some nearly sure, but none absolutely certain. Now, we scientists are used to this, and we take it for granted that it is perfectly consistent to be unsure, that it is possible to live and not know. But I don’t know whether everyone realizes this is true. Our freedom to doubt was born out of a struggle against authority in the early days of science. It was a very deep and strong struggle: permit us to question — to doubt — to not be sure. I think that it is important that we do not forget this struggle and thus perhaps lose what we have gained.

This story takes place a half a billion years ago-an inconceivably long time ago, when this planet would be all but recognizable to you. Nothing at all stirred on the land except the wind and the dust. Not a single blade of grass waved in the wind, not a single cricket chirped, not a single bird soared in the sky. All these things were tens of millions of years away in the future. But of course there was an anthropologist on hand. What sort of world would it be without an anthropologist? He was, however a very depressed and disillusioned anthropologist, for he'd been everywhere on the planet looking for someone to interview, and every tape in his knapsack was as blank as the sky. But one day as he was moping alongside the ocean he saw what seemed to be a living creature in the shallows off shore. It was nothing to brag about, just sort of a squishy blob, but it was the only prospect he'd seen in all his journeys, so he waded out to where it was bobbing in the waves. He greeted the creature politely and was greeted in kind, and soon the two of them were good friends. The anthropologist explained as well as he could that he was a student of life-styles and customs, and begged his new friend for information of this sort, which was readily forthcoming. ‘And now’, he said at last, ‘I'd like to get on tape in your own words some of the stories you tell among yourselves.’ ‘Stories?’ the other asked. ‘You know, like your creation myth, if you have one.’ ‘What is a creation myth?’ the creature asked. ‘Oh, you know,’ the anthropologist replied, ‘the fanciful tale you tell your children about the origins of the world.’ Well, at this, the creature drew itself up indignantly- at least as well as a squishy blob can do- and replied that his people had no such fanciful tale. ‘You have no account of creation then?’ ‘Certainly we have an account of creation,’ the other snapped. ‘But its definitely not a myth.’ ‘Oh certainly not,’ the anthropologist said, remembering his training at last. ‘Ill be terribly grateful if you share it with me.’ ‘Very well,’ the creature said. ‘But I want you to understand that, like you, we are a strictly rational people, who accept nothing that is not based on observation, logic, and scientific method.’ ‘"Of course, of course,’ the anthropologist agreed. So at last the creature began its story. ‘The universe,’ it said, ‘was born a long, long time ago, perhaps ten or fifteen billion years ago. Our own solar system-this star, this planet, and all the others- seem to have come into being some two or three billion years ago. For a long time, nothing whatever lived here. But then, after a billion years or so, life appeared.’ ‘Excuse me,’ the anthropologist said. ‘You say that life appeared. Where did that happen, according to your myth- I mean, according to your scientific account.’ The creature seemed baffled by the question and turned a pale lavender. ‘Do you mean in what precise spot?’ ‘No. I mean, did this happen on land or in the sea?’ ‘Land?’ the other asked. ‘What is land?’ ‘Oh, you know,’ he said, waving toward the shore, ‘the expanse of dirt and rocks that begins over there.’ The creature turned a deeper shade of lavender and said, ‘I cant imagine what you're gibbering about. The dirt and rocks over there are simply the lip of the vast bowl that holds the sea.’ ‘Oh yes,’ the anthropologist said, ‘I see what you mean. Quite. Go on.’ ‘Very well,’ the other said. ‘For many millions of centuries the life of the world was merely microorganisms floating helplessly in a chemical broth. But little by little, more complex forms appeared: single-celled creatures, slimes, algae, polyps, and so on.’ ‘But finally,’ the creature said, turning quite pink with pride as he came to the climax of his story, ‘but finally jellyfish appeared!

At first he found it amusing. He coined a law intended to have the humor of a Parkinson’s law that "The number of rational hypotheses that can explain any given phenomenon is infinite." It pleased him never to run out of hypotheses. Even when his experimental work seemed dead-end in every conceivable way, he knew that if he just sat down and muddled about it long enough, sure enough, another hypothesis would come along. And it always did. It was only months after he had coined the law that he began to have some doubts about the humor or benefits of it. If true, that law is not a minor flaw in scientific reasoning. The law is completely nihilistic. It is a catastrophic logical disproof of the general validity of all scientific method! If the purpose of scientific method is to select from among a multitude of hypotheses, and if the number of hypotheses grows faster than experimental method can handle, then it is clear that all hypotheses can never be tested. If all hypotheses cannot be tested, then the results of any experiment are inconclusive and the entire scientific method falls short of its goal of establishing proven knowledge

The egg industry itself funded research on Salmonella and the various ways to cook eggs. What did they find? Salmonella in eggs can survive scrambled, over-easy, and sunny-side-up cooking methods. Sunny side up was found to be the riskiest. The industry-funded researchers bluntly concluded: “The sunny-side-up method should be considered unsafe.”84 In other words, even the egg industry itself knows that its product, prepared in a manner that millions of Americans eat on any given day all across the country, is unsafe.

You frequently state, and in your letter you imply, that I have developed a completely one-sided outlook and look at everything in terms of science. Obviously my method of thought and reasoning is influenced by a scientific training – if that were not so my scientific training will have been a waste and a failure. But you look at science (or at least talk of it) as some sort of demoralizing invention of man, something apart from real life, and which must be cautiously guarded and kept separate from everyday existence. But science and everyday life cannot and should not be separated. Science, for me, gives a partial explanation of life. In so far as it goes, it is based on fact, experience and experiment. Your theories are those which you and many other people find easiest and pleasantest to believe, but so far as I can see, they have no foundation other than they leaf to a pleasanter view of life (and an exaggerated idea of our own importance)... I agree that faith is essential to success in life (success of any sort) but I do not accept your definition of faith, i.e. belief in life after death. In my view, all that is necessary for faith is the belief that by doing our best we shall come nearer to success and that success in our aims (the improvement of the lot of mankind, present and future) is worth attaining. Anyone able to believe in all that religion implies obviously must have such faith, but I maintain that faith in this world is perfectly possible without faith in another world… It has just occurred to me that you may raise the question of the creator. A creator of what? ... I see no reason to believe that a creator of protoplasm or primeval matter, if such there be, has any reason to be interested in our significant race in a tiny corner of the universe, and still less in us, as still more significant individuals. Again, I see no reason why the belief that we are insignificant or fortuitous should lessen our faith – as I have defined it.

From the study of the development of human intelligence, in all directions, and through all times, the discovery arises of a great fundamental law, to which it is necessarily subject, and which has a solid foundation of proof, both in the facts of our organization and in our historical experience. The law is this: that each of our leading conceptions -- each branch of our knowledge -- passes successively through three different theoretical conditions: the theological, or fictitious; the metaphysical, or abstract; and the scientific, or positive. In other words, the human mind, by its nature, employs in its progress three methods of philosophizing, the character of which is essentially different, and even radically opposed: namely, the theological method, the metaphysical, and the positive. Hence arise three philosophies, or general systems of conceptions on the aggregate of phenomena, each of which excludes the others. The first is the necessary point of departure of the human understanding, and the third is its fixed and definitive state. The second is merely a state of transition.

In fact, certainty exists in very different modes. The kind of certainty afforded by a verification that has passed through doubt is different from the immediate living certainty with which all ends and values appear in human consciousness when they make an absolute claim. But the certainty of science is very different from this kind of certainty that is acquired in life. Scientific certainty always has something Cartesian about it. It is the result of a critical method that seeks only to allow what cannot be doubted. This certainty, then, does not proceed from doubts and their being overcome, but is always anterior to any process of being doubted.

Cherish your doubts, for doubt is the handmaiden of truth. Doubt is the key to the door of knowledge; it is the servant of discovery. A belief which may not be questioned binds us to error, for there is incompleteness and imperfection in every belief. Doubt is the touchstone of truth; it is an acid which eats away the false. Let no man fear for the truth, that doubt may consume it; for doubt is a testing of belief. The truth stands boldly and unafraid; it is not shaken by the testing; For truth, if it be truth, arises from each testing stronger, more secure. He that would silence doubt is filled with fear; the house of his spirit is built on shifting sands. But he that fears no doubt, and knows its use, is founded on a rock. He shall walk in the light of growing knowledge; the work of his hands shall endure. Therefore let us not fear doubt, but let us rejoice in its help: It is to the wise as a staff to the blind; doubt is the handmaiden of truth.

Pseudoscience is almost always recognizable from a distance, and easy to confirm on close examination. Science is, however, not immune from hubris, and bad science can be tougher to spot. Those of us who make a living from science or science media must display scientific integrity. We must constantly test our assumptions and fight the siren song of consensus when our data tells us to be contrarian. We must remain independent of political or religious bias in evaluating our work. We must admit when we are wrong, and remain willing to evolve when verifiable data demands change. We must admit when we are uncertain, remain humble in advances, and offer courageous and independent advice grounded in science.

With the growth of civilisation in Europe, and with the revival of letters and of science in the fourteenth and fifteenth centuries, the ethical and intellectual criticism of theology once more recommenced, and arrived at a temporary resting-place in the confessions of the various reformed Protestant sects in the sixteenth century; almost all of which, as soon as they were strong enough, began to persecute those who carried criticism beyond their own limit. But the movement was not arrested by these ecclesiastical barriers, as their constructors fondly imagined it would be; it was continued, tacitly or openly, by Galileo, by Hobbes, by Descartes, and especially by Spinoza, in the seventeenth century; by the English Freethinkers, by Rousseau, by the French Encyclopaedists, and by the German Rationalists, among whom Lessing stands out a head and shoulders taller than the rest, throughout the eighteenth century; by the historians, the philologers, the Biblical critics, the geologists, and the biologists in the nineteenth century, until it is obvious to all who can see that the moral sense and the really scientific method of seeking for truth are once more predominating over false science. Once more ethics and theology are parting company.

Each religion makes scores of purportedly factual assertions about everything from the creation of the universe to the afterlife. But on what grounds can believers presume to know that these assertions are true? The reasons they give are various, but the ultimate justification for most religious people’s beliefs is a simple one: we believe what we believe because our holy scriptures say so. But how, then, do we know that our holy scriptures are factually accurate? Because the scriptures themselves say so. Theologians specialize in weaving elaborate webs of verbiage to avoid saying anything quite so bluntly, but this gem of circular reasoning really is the epistemological bottom line on which all 'faith' is grounded. In the words of Pope John Paul II: 'By the authority of his absolute transcendence, God who makes himself known is also the source of the credibility of what he reveals.' It goes without saying that this begs the question of whether the texts at issue really were authored or inspired by God, and on what grounds one knows this. 'Faith' is not in fact a rejection of reason, but simply a lazy acceptance of bad reasons. 'Faith' is the pseudo-justification that some people trot out when they want to make claims without the necessary evidence. But of course we never apply these lax standards of evidence to the claims made in the other fellow’s holy scriptures: when it comes to religions other than one’s own, religious people are as rational as everyone else. Only our own religion, whatever it may be, seems to merit some special dispensation from the general standards of evidence. And here, it seems to me, is the crux of the conflict between religion and science. Not the religious rejection of specific scientific theories (be it heliocentrism in the 17th century or evolutionary biology today); over time most religions do find some way to make peace with well-established science. Rather, the scientific worldview and the religious worldview come into conflict over a far more fundamental question: namely, what constitutes evidence. Science relies on publicly reproducible sense experience (that is, experiments and observations) combined with rational reflection on those empirical observations. Religious people acknowledge the validity of that method, but then claim to be in the possession of additional methods for obtaining reliable knowledge of factual matters — methods that go beyond the mere assessment of empirical evidence — such as intuition, revelation, or the reliance on sacred texts. But the trouble is this: What good reason do we have to believe that such methods work, in the sense of steering us systematically (even if not invariably) towards true beliefs rather than towards false ones? At least in the domains where we have been able to test these methods — astronomy, geology and history, for instance — they have not proven terribly reliable. Why should we expect them to work any better when we apply them to problems that are even more difficult, such as the fundamental nature of the universe? Last but not least, these non-empirical methods suffer from an insuperable logical problem: What should we do when different people’s intuitions or revelations conflict? How can we know which of the many purportedly sacred texts — whose assertions frequently contradict one another — are in fact sacred?

Things that look like they were designed, probably were... If intelligence is an operative component of the universe, a science that methodologically excludes its existence will be susceptible to being trapped in an endless chase for materialistic causes that do not exist... Where there are sufficient grounds for inferring intelligent causation, based on evidence of "specified complexity," it should be considered as a component of scientific theories. Inclusion of intelligent causation in the scientific equation is not novel and has not impeded the practice of science in the past, e.g. Newton and Kepler, in an age when science was not constrained by a philosophical materialism, and by many current scientists who have remained open to following the evidence where it leads.

Only a few centuries ago, a mere second in cosmic time, we knew nothing of where or when we were. Oblivious to the rest of the cosmos, we inhabited a kind of prison, a tiny universe bounded by a nutshell. How did we escape from the prison? It was the work of generations of searchers who took five simple rules to heart: 1. Question authority. No idea is true just because someone says so, including me. 2. Think for yourself. Question yourself. Don't believe anything just because you want to. Believing something doesn't make it so. 3. Test ideas by the evidence gained from observation and experiment. If a favorite idea fails a well-designed test, it's wrong. Get over it. 4. Follow the evidence wherever it leads. If you have no evidence, reserve judgment. And perhaps the most important rule of all... 5. Remember: you could be wrong. Even the best scientists have been wrong about some things. Newton, Einstein, and every other great scientist in history -- they all made mistakes. Of course they did. They were human. Science is a way to keep from fooling ourselves, and each other.

Thus, by science I mean, first of all, a worldview giving primacy to reason and observation and a methodology aimed at acquiring accurate knowledge of the natural and social world. This methodology is characterized, above all else, by the critical spirit: namely, the commitment to the incessant testing of assertions through observations and/or experiments — the more stringent the tests, the better — and to revising or discarding those theories that fail the test. One corollary of the critical spirit is fallibilism: namely, the understanding that all our empirical knowledge is tentative, incomplete and open to revision in the light of new evidence or cogent new arguments (though, of course, the most well-established aspects of scientific knowledge are unlikely to be discarded entirely). . . . I stress that my use of the term 'science' is not limited to the natural sciences, but includes investigations aimed at acquiring accurate knowledge of factual matters relating to any aspect of the world by using rational empirical methods analogous to those employed in the natural sciences. (Please note the limitation to questions of fact. I intentionally exclude from my purview questions of ethics, aesthetics, ultimate purpose, and so forth.) Thus, 'science' (as I use the term) is routinely practiced not only by physicists, chemists and biologists, but also by historians, detectives, plumbers and indeed all human beings in (some aspects of) our daily lives. (Of course, the fact that we all practice science from time to time does not mean that we all practice it equally well, or that we practice it equally well in all areas of our lives.)

Yoga has been superficially misunderstood by certain Western writers, but its critics have never been its practitioners. Among many thoughtful tributes to yoga may be mentioned one by Dr. C. G. Jung, the famous Swiss psychologist. “When a religious method recommends itself as ‘scientific,’ it can be certain of its public in the West. Yoga fulfills this expectation,” Dr. Jung writes.10 “Quite apart from the charm of the new and the fascination of the half-understood, there is good cause for Yoga to have many adherents. It offers the possibility of controllable experience and thus satisfies the scientific need for ‘facts’; and, besides this, by reason of its breadth and depth, its venerable age, its doctrine and method, which include every phase of life, it promises undreamed-of possibilities. “Every religious or philosophical practice means a psychological discipline, that is, a method of mental hygiene. The manifold, purely bodily procedures of Yoga11 also mean a physiological hygiene which is superior to ordinary gymnastics and breathing exercises, inasmuch as it is not merely mechanistic and scientific, but also philosophical; in its training of the parts of the body, it unites them with the whole of the spirit, as is quite clear, for instance, in the Pranayama exercises where Prana is both the breath and the universal dynamics of the cosmos…. “Yoga practice...would be ineffectual without the concepts on which Yoga is based. It combines the bodily and the spiritual in an extraordinarily complete way. “In the East, where these ideas and practices have developed, and where for several thousand years an unbroken tradition has created the necessary spiritual foundations, Yoga is, as I can readily believe, the perfect and appropriate method of fusing body and mind together so that they form a unity which is scarcely to be questioned. This unity creates a psychological disposition which makes possible intuitions that transcend consciousness.

You may have read or heard about the so-called positive thinkers of the West. They say just the opposite -- they don't know what they are saying. They say, "When you breathe out, throw out all your misery and negativity; and when you breathe in, breathe in joy, positivity, happiness, cheerfulness." Atisha's method is just the opposite: when you breathe in, breathe in all the misery and suffering of all the beings of the world -- past, present and future. And when you breathe out, breathe out all the joy that you have, all the blissfulness that you have, all the benediction that you have. Breathe out, pour yourself into existence. This is the method of compassion: drink in all the suffering and pour out all the blessings. And you will be surprised if you do it. The moment you take all the sufferings of the world inside you, they are no longer sufferings. The heart immediately transforms the energy. The heart is a transforming force: drink in misery, and it is transformed into blissfulness... then pour it out. Once you have learned that your heart can do this magic, this miracle, you would like to do it again and again. Try it. It is one of the most practical methods -- simple, and it brings immediate results. Do it today, and see. That is one of the approaches of Buddha and all his disciples. Atisha is one of his disciples, in the same tradition, in the same line. Buddha says again and again to his disciples, "IHI PASSIKO: come and see!" They are very scientific people. Buddhism is the most scientific religion on the earth; hence, Buddhism is gaining more and more ground in the world every day. As the world becomes more intelligent, Buddha will become more and more important. It is bound to be so. As more and more people come to know about science, Buddha will have great appeal, because he will convince the scientific mind -- because he says, "Whatsoever I am saying can be practiced." And I don't say to you, "Believe it," I say, "Experiment with it, experience it, and only then if you feel it yourself, trust it. Otherwise there is no need to believe.

And Mallow laughed joyously. "You've missed, Sutt, missed as badly as the Commdor himself. You've missed everything, and understood nothing. The Empire has always been a realm of colossal resources. They've calculated everything in planets, in stellar systems, in whole sectors of the Galaxy. Their generators are gigantic because they thought in gigantic fashion. "But we,—we, our little Foundation, our single world almost without metallic resources,—have had to work with brute economy. Our generators have had to be the size of our thumb, because it was all the metal we could afford. We had to develop new techniques and new methods,—techniques and methods the Empire can't follow because they have degenerated past the stage where they can make any vital scientific advance. "With all their nuclear shields, large enough to protect a ship, a city, an entire world; hey could never build one to protect a single man. To supply light and heat to a city, they have motors six stories high,—I saw them—where ours could fit into this room. And when I told one of their nuclear specialists that a lead container the size of a walnut contained a nuclear generator, he almost choked with indignation on the spot. "Why, they don't even understand their own colossi any longer. The machines work from generation to generation automatically and the caretakers are a hereditary caste who would be helpless if a single D-tube in all that vast structure burnt out. "The whole war is a battle between these two systems; between the Empire and the Foundation; between the big and the little. To seize control of a world, they bribe with immense ships that can make war, but lack all economic significance. We, on the other hand, bribe with little things, useless in war, but vital to prosperity and profits. "A king, or a Commdor, will take the ships and even make war. Arbitrary rulers throughout history have bartered their subjects' welfare for what they consider honor, and glory, and conquest. But it's still the little things in life that count—and Asper Argo won't stand up against the economic depression that will sweep all Korell in two or three years.

It’s no one’s fault really,” he continued. “A big city cannot afford to have its attention distracted from the important job of being a big city by such a tiny, unimportant item as your happiness or mine.” This came out of him easily, assuredly, and I was suddenly interested. On closer inspection there was something aesthetic and scholarly about him, something faintly professorial. He knew I was with him, listening, and his grey eyes were kind with offered friendliness. He continued: “Those tall buildings there are more than monuments to the industry, thought and effort which have made this a great city; they also occasionally serve as springboards to eternity for misfits who cannot cope with the city and their own loneliness in it.” He paused and said something about one of the ducks which was quite unintelligible to me. “A great city is a battlefield,” he continued. “You need to be a fighter to live in it, not exist, mark you, live. Anybody can exist, dragging his soul around behind him like a worn-out coat; but living is different. It can be hard, but it can also be fun; there’s so much going on all the time that’s new and exciting.” I could not, nor wished to, ignore his pleasant voice, but I was in no mood for his philosophising. “If you were a negro you’d find that even existing would provide more excitement than you’d care for.” He looked at me and suddenly laughed; a laugh abandoned and gay, a laugh rich and young and indescribably infectious. I laughed with him, although I failed to see anything funny in my remark. “I wondered how long it would be before you broke down and talked to me,” he said, when his amusement had quietened down. “Talking helps, you know; if you can talk with someone you’re not lonely any more, don’t you think?” As simple as that. Soon we were chatting away unreservedly, like old friends, and I had told him everything. “Teaching,” he said presently. “That’s the thing. Why not get a job as a teacher?” “That’s rather unlikely,” I replied. “I have had no training as a teacher.” “Oh, that’s not absolutely necessary. Your degrees would be considered in lieu of training, and I feel sure that with your experience and obvious ability you could do well.” “Look here, Sir, if these people would not let me near ordinary inanimate equipment about which I understand quite a bit, is it reasonable to expect them to entrust the education of their children to me?” “Why not? They need teachers desperately.” “It is said that they also need technicians desperately.” “Ah, but that’s different. I don’t suppose educational authorities can be bothered about the colour of people’s skins, and I do believe that in that respect the London County Council is rather outstanding. Anyway, there would be no need to mention it; let it wait until they see you at the interview.” “I’ve tried that method before. It didn’t work.” “Try it again, you’ve nothing to lose. I know for a fact that there are many vacancies for teachers in the East End of London.” “Why especially the East End of London?” “From all accounts it is rather a tough area, and most teachers prefer to seek jobs elsewhere.” “And you think it would be just right for a negro, I suppose.” The vicious bitterness was creeping back; the suspicion was not so easily forgotten. “Now, just a moment, young man.” He was wonderfully patient with me, much more so than I deserved. “Don’t ever underrate the people of the East End; from those very slums and alleyways are emerging many of the new breed of professional and scientific men and quite a few of our politicians. Be careful lest you be a worse snob than the rest of us. Was this the kind of spirit in which you sought the other jobs?

A disdain for the practical swept the ancient world. Plato urged astronomers to think about the heavens, but not to waste their time observing them. Aristotle believed that: “The lower sort are by nature slaves, and it is better for them as for all inferiors that they should be under the rule of a master.… The slave shares in his master’s life; the artisan is less closely connected with him, and only attains excellence in proportion as he becomes a slave. The meaner sort of mechanic has a special and separate slavery.” Plutarch wrote: “It does not of necessity follow that, if the work delight you with its grace, the one who wrought it is worthy of esteem.” Xenophon’s opinion was: “What are called the mechanical arts carry a social stigma and are rightly dishonoured in our cities.” As a result of such attitudes, the brilliant and promising Ionian experimental method was largely abandoned for two thousand years. Without experiment, there is no way to choose among contending hypotheses, no way for science to advance. The anti-empirical taint of the Pythagoreans survives to this day. But why? Where did this distaste for experiment come from? An explanation for the decline of ancient science has been put forward by the historian of science, Benjamin Farrington: The mercantile tradition, which led to Ionian science, also led to a slave economy. The owning of slaves was the road to wealth and power. Polycrates’ fortifications were built by slaves. Athens in the time of Pericles, Plato and Aristotle had a vast slave population. All the brave Athenian talk about democracy applied only to a privileged few. What slaves characteristically perform is manual labor. But scientific experimentation is manual labor, from which the slaveholders are preferentially distanced; while it is only the slaveholders—politely called “gentle-men” in some societies—who have the leisure to do science. Accordingly, almost no one did science. The Ionians were perfectly able to make machines of some elegance. But the availability of slaves undermined the economic motive for the development of technology. Thus the mercantile tradition contributed to the great Ionian awakening around 600 B.C., and, through slavery, may have been the cause of its decline some two centuries later. There are great ironies here.
