Here is a fulfillment of long centuries of civilization and culture; here, in romantic love, more than the triumph of thought or the victories of power is the topmost reach of human beings.

Sir William Hunter, estimated that 40,000,000 of the people of India were seldom or never able to satisfy their hunger. In 1901, 272,000 died of plague introduced from abroad, in 1902, 500,000 died of plague; in 1903, 800,000; in 1904, 1,000,000. We can now understand why there are famines in India. Their cause, in plain terms, is not the absence of food, but the inability of the people to pay for it. It was hoped the railways would solve the problem...the fact that the worst famines have come since the building of the railways...behind all these, as the fundamental source of the terrible famines in India, lies such merciless exploitation, such unbalanced exploitation of goods, and such brutal collection of high taxes in the very midst of famine....

The invention and spread of contraceptives is the proximate cause of our changing morals. The old moral code restricted sexual experience to marriage, because copulation could not be effectively separated from parentage, and parentage could be made responsible only through marriage. But to-day the dissociation of sex from reproduction has created a situation unforeseen by our fathers. All the relations of men and women are being changed by this one factor; and the moral code of the future will have to take account of these new facilities which invention has placed at the service of ancient desires.

Man is as young as the risks he takes.

India was the motherland of our race, and Sanskrit the mother of Europe's languages: she was the mother of our philosophy; mother, through the Arabs, of much of our mathematics; mother, through the Buddha, of the ideals embodied in Christianity; mother, through the village community, of self-government and democracy. Mother India is in many ways the mother of us all.

Life is that which can hold a purpose for three thousand years and never yield. The individual fails, but life succeeds. The individual is foolish, but life holds in its blood and seed the wisdom of generations. The individual dies, but life, tireless and undiscourageble, goes on, wondering, longing, planning, trying, mounting, longing.

Most of our literature and social philosophy after 1850 was the voice of freedom against authority, of the child against the parent, of the pupil against the teacher. Through many years I shared in that individualistic revolt. I do not regret it; it is the function of youth to defend liberty and innovation, of the old to defend order and tradition, and of middle age to find a middle way. But now that I too am old, I wonder whether the battle I fought was not too completely won. Let us say humbly but publicly that we resent corruption in politics, dishonesty in business, faithlessness in marriage, pornography in literature, coarseness in language, chaos in music, meaninglessness in art.

To all Christian governments Christianity was not a rule of means but a means of rule; Christ was for the people, Machiavelli was preferred by the kings. The state in some measure had civilized man, but who would civilize the state?

The death of Alexander (323 BC) quickened this process of decay. The boy-emperor, barbarian though he remained after all of Aristotle's tutoring, had yet learned to revere the rich culture of Greece, and had dreamed of spreading that culture through the Orient in the wake of his victorious armies.... But he had underrated the inertia and resistance of the Oriental mind, and the mass and depth of Oriental culture. It was only a youthful fancy, after all, to suppose that so immature and unstable a civilization as that of Greece could be imposed upon a civilization immeasurably more widespread, and rooted in the most venerable traditions. The quantity of Asia proved too much for the quality of Greece.

Wisdom, if it were young, would cherish love, nursing it with devotion, deepening it with sacrifice, vitalizing with parentage, making all things subordinate to it till the end. Even though it consumes us in its service and overwhelms us with tragedy, even though it breaks us down with separations, let it be first. How can it matter what price we pay for love?

The news of this barbaric orgy of military sadism was kept from the world for half a year. A belated commission of inquiry was appointed by the Government. A committee appointed by the Indian National Congress made a more through investigation and reported 1,200 killed, and 3,600 wounded. Gen. Dyer was censured by the House of Commons, exonerated by the House of Lords, and was retired on a pension. Thinking this was insufficient the militarists of the Empire raised a fund of $150,000 for him and presented him with a jeweled sword of honor. (source: The Case for India - By Will Durant Simon and Schuster, New York. 1930 p. This book was banned by the British Government. Durant held the view that no part of the world suffered so much poverty andoppression as India did and that this was largely due to British imperialism).

I know how unfashionable it is now to acknowledge in life or history any genius loftier than ourselves. Our democratic dogma has leveled not only all voters but all leaders; we delight to show that living geniuses are only mediocrities, and that dead ones are myths. ... Since it is contrary to good manners to exalt ourselves, we achieve the same result by slyly indicating how inferior are the great men of the earth. In some of us, perhaps, it is a noble and merciless asceticism, which would root out of our hearts the last vestige of worship and adoration, lest the old gods should return and terrify us again. For my part, I cling to this final religion, and discover in it a content and stimulus more lasting than came from the devotional ecstasies of youth.

Happiness is the free play of the instincts, and so is youth.

It is true that even across the Himalayan barrier India has sent to the west, such gifts as grammar and logic, philosophy and fables, hypnotism and chess, and above all numerals and the decimal system.

Space, subjectively, is the coexistence of perceptions - perceiving two objects at once.

Sixty years ago I knew everything. Now I know nothing. Education is a progressive discovery of our own ignorance.

Power dements even more than it corrupts, lowering the guard of foresight and raising the haste of action.

Those who try to include all life when trying to determine justice: Should a man be executed for killing a fly? No? The fly has a short life span? The fly is small? All these rationalizations can be applied to you, by a creature that lives longer, is bigger, etc. #philosophy 

Scientific revolutions are inaugurated by a growing sense... that an existing paradigm has ceased to function adequately in the exploration of an aspect of nature to which that paradigm itself had previously led the way. p. 91

The subject of a gestalt demonstration knows that his perception has shifted because he can make it shift back and forth repeatedly while he holds the same book or piece of paper in his hands. Aware that nothing in his environment has changed, he directs his attention increasingly not to the figure (duck or rabbit) but to the lines of the paper he is looking at. Ultimately he may even learn to see those lines without seeing either of the figures, and he may then say (what he could not legitimately have said earlier) that it is these lines that he really sees but that he sees them alternately as a duck and as a rabbit. ...As in all similar psychological experiments, the effectiveness of the demonstration depends upon its being analyzable in this way. Unless there were an external standard with respect to which a switch of vision could be demonstrated, no conclusion about alternate perceptual possibilities could be drawn. 

These examples point to the third and most fundamental aspect of the incommensurability of competing paradigms. In a sense that I am unable to explicate further, the proponents of competing paradigms practice their trades in different worlds. One contains constrained bodies that fall slowly, the other pendulums that repeat their motions again and again. In one, solutions are compounds, in the other mixtures. One is embedded in a flat, the other in a curved, matrix of space. Practicing in different worlds, the two groups of scientists see different things when they look from the same point in the same direction. Again, that is not to say that they can see anything they please. Both are looking at the world, and what they look at has not changed. But in some areas they see different things, and they see them in different relations one to the other. That is why a law that cannot even be demonstrated to one group of scientists may occasionally seem intuitively obvious to another. p. 149

We may, to be more precise, have to relinquish the notion, explicit or implicit, that changes of paradigm carry scientists and those who learn from them closer and closer to the truth.

By now it may be clear that the position I'm developing is a sort of post-Darwinian Kantianism.

The scientific enterprise as a whole does from time to time prove useful, open up new territory, display order, and test long-accepted belief. Nevertheless, the individual engaged on a normal research problem is almost never doing any one of these things. Once engaged, his motivation is of a rather different sort. What then challenges him is the conviction that, if only he is skillful enough, he will succeed in solving a puzzle that no one before has solved or solved so well.

Normal science, the activity in which most scientists inevitably spend almost all their time, is predicated on the assumption that the scientific community knows what the world is like. Normal science often suppresses fundamental novelties because they are necessarily subversive of its basic commitments.

Only when they must choose between competing theories do scientists behave like philosophers.

Scientists work from models acquired through education and through subsequent exposure to the literature often without quite knowing or needing to know what characteristics have given these models the status of community paradigms.

"Normal science" means research firmly based upon one or more past scientific achievements, achievements that some particular scientific community acknowledges for a time as supplying the foundation for its further practice.

I suggest that scientific knowledge, though logically more articulate and far more complex, is of this sort. The books and teachers from whom it is acquired present concrete examples together with a multitude of theoretical generalizations. Both are essential carriers of knowledge, and it is therefore Pickwickian to seek a methodological criterion that supposes the scientist can specify in advance whether each imaginable instance fits or would falsify his theory.

Normal science, the puzzle-solving activity we have just examined, is a highly cumulative enterprise, eminently successful in its aim, the steady extension of the scope and precision of scientific knowledge. In all these respects it fits with great precision the most usual image of scientific work. Yet one standard product of the scientific enterprise is missing. Normal science does not aim at novelties of fact or theory and, when successful, finds none.

Men whose research is based on shared paradigms are committed to the same rules and standards for scientific practice. That commitment and the apparent consensus it produces are prerequisites for normal science, i.e., for the genesis and continuation of a particular research tradition.

To my complete surprise, that exposure to out-of-date scientific theory and practice radically undermined some of my basic conceptions about the nature of science and the reasons for its special success.Those conceptions were ones I had previously drawn partly from scientific training itself and partly from a long-standing avocational interest in the philosophy of science. Somehow, whatever their pedagogic utility and their abstract plausibility, those notions did not at all fit the enterprise that historical study displayed. Yet they were and are fundamental to many discussions of science, and their failures of verisimilitude therefore seemed thoroughly worth pursuing. The result was a drastic shift in my career plans, a shift from physics to history of science and then, gradually, from relatively straightforward historical problems back to the more philosophical concerns that had initially led me to history.

We must now ask how changes of this sort can come about, considering first discoveries, or novelties of fact, and then inventions, or novelties of theory. That distinction between discovery and invention or between fact and theory will, however, immediately prove to be exceedingly artificial.

Ever since prehistoric antiquity one field of study after another has crossed the divide between what the historian might call its prehistory as a science and its history proper. These transitions to maturity have seldom been so sudden or so unequivocal as my necessarily schematic discussion may have implied. But neither have they been historically gradual, coextensive, that is to say, with the entire development of the fields within which they occurred.

Somehow, the practice of astronomy, physics, chemistry or biology normally fails to evoke the controversies over fundamentals that today seem endemic among, say, psychologists or sociologists. Attempting to discover the source of that difference led me to recognize the role in scientific research of what I have since called "paradigms." These I take to be universally recognized scientific achievements that for a time provide model problems and solutions for a community of practitioners.

In science, as in the playing card experiment, novelty emerges only with difficulty, manifested by resistance, against a background provided by expectation.

Few people who are not actually practitioners of a mature science realize how much mop-up work of this sort a paradigm leaves to be done or quite how fascinating such work can prove in the execution.

History, if viewed as a repository for more than anecdote or chronology, could produce a decisive transformation in the image of science by which we are now possessed.

In the development of any science, the first received paradigm is usually felt to account quite successfully for most of the observations and experiments easily accessible to that science's practitioners. Further development, therefore, ordinarily calls for the construction of elaborate equipment, the development of an esoteric vocabulary and skills, and a refinement of concepts that increasingly lessens their resemblance to their usual common-sense prototypes. That professionalization leads, on the one hand, to an immense restriction of the scientist's vision and to a considerable resistance to paradigm change. The science has become increasingly rigid. On the other hand, within those areas to which the paradigm directs the attention of the group, normal science leads to a detail of information and to a precision of the observation-theory match that could be achieved in no other way.

These three classes of problems-determination of significant fact, matching of facts with theory, and articulation of theory-exhaust, I think, the literature of normal science, both empirical and theoretical. They do not, of course, quite exhaust the entire literature of science. There are also extraordinary problems, and it may well be their resolution that makes the scientific enterprise as a whole so particularly worthwhile. But extraordinary problems are not to be had for the asking. They emerge only on special occasions prepared by the advance of normal research.

Out-of-date theories are not in principle unscientific because they have been discarded. That choice, however, makes it difficult to see scientific development as a process of accretion.

Philosophers of science have repeatedly demonstrated that more than one theoretical construction can always be placed upon a given collection of data. History of science indicates that, particularly in the early developmental stages of a new paradigm, it is not even very difficult to invent such alternates. But that invention of alternates is just what scientists seldom undertake except during the pre-paradigm stage of their science's development and at very special occasions during its subsequent evolution. So long as the tools a paradigm supplies continue to prove capable of solving the problems it defines, science moves fastest and penetrates most deeply through confident employment of those tools. The reason is clear. As in manufacture so in science-retooling is an extravagance to be reserved for the occasion that demands it. The significance of crises is the indication they provide that an occasion for retooling has arrived.

Alas! such is the miseducation of these days, it is only among those that are called the uneducated classes - those educated by experience - that you can look for a Man. Even among these, such a sight is growing daily rarer. My father, in several respects, has not, that I can think of, left his fellow. Perhaps among Scottish peasants what Samuel Johnson was among English authors. I have a sacred pride in my peasant father, and would not exchange him, even now, for any king known to me. Gold and the guinea stamp - the Man and the clothes of the man. Let me thank God for that greatest of blessings, and strive to live worthily of it.

If they be inhabited, what a scope for misery and folly; if they be un-inhabited, what a waste of space.

If you find many people who are hard and indifferent to you in a world that you consider to be unhospitable and cruel-as often, indeed, happens to a tender-hearted, stirring young creature-you will also find there are noble hearts who will look kindly on you, and their help will be precious to you beyond price.

Had there not been a natural goodness and indestructible force in my father, I see not how be could have bodied himself forth from these mean impediments. I suppose good precepts were not wanting. There was the Bible to read. Old John Orr, the schoolmaster, used from time to time to lodge with them; be was religious and enthusiastic (though in practice irregular with drink). In my grandfather, also, there seems to have been a certain geniality; for instance, he and a neighbor, Thomas Hogg, read "Anson's Voyages;" also tho "Arabian Nights," for which latter my father, armed with zealous conviction, scrupled not to censure them openly. By one means and another, at an early age he had acquired principles, lights that not only flickered, but shone steadily to guide his way.

The habits of study acquired at Universities are of the highest importance in after-life. At the season when you are in young years the whole mind is, as it were, fluid, and is capable of forming itself into any shape that the owner of the mind pleases to order it to form itself into. The mind is in a fluid state, but it hardens up gradually to the consistency of rock or iron, and you cannot alter the habits of an old man, but as he has begun he will proceed and go on to the last.

The more I reflect on it, the more I must admire how completely nature had taught him; how completely he was devoted to his work, to the task of his life, and content to let all pass by unheeded that had not relation to this. It is a singular fact, for example, that though a man of such openness and clearness, he had never, I believe, read three pages of Burns's poems. Not even when all about him became noisy and enthusiastic, I the loudest, on that matter, did he feel it worth while to renew his investigation of it, or once turn his face towards it. The poetry he liked (he did not call it poetry) was truth, and the wisdom of reality. Burns, indeed, could have done nothing for him. As high a greatness hung over his world as over that of Burns - the ever-present greatness of the Infinite itself. Neither was he, like Burns, called to rebel against the world, but to labor patiently at his task there, uniting the possible with the necessary to bring out the real, wherein also lay an ideal.

Can there be a more horrible object in existence than an eloquent man not speaking the truth?

The force that had been lent my father he honorably expended in manful well-doing. A portion of this planet bears beneficent traces of his strong hand and strong head. Nothing that he undertook to do but he did it faithfully and like a true man. I shall look on the houses he built with a certain proud interest. They stand firm and sound to the heart all over his little district.
