Published in 1968, The Lessons of History is a book written by historians Will and Ariel Durant.

After completing their 10-volume series The Story of Civilization, the Durants decided to write a summary of what they’ve learnt. They did this by examining the lessons learnt from history from multiple perspectives.

The Lessons of History is a short but mind-blowing read. In fact, it probably has the highest per-page wisdom of any book I’ve read.

More books should be like this.

Without further ado, here are my notes from the book.

NOTE. The passages are taken directly from the book.

Biology

  • The laws of biology are the fundamental lessons of history. We are subject to the processes and trials of evolution, to the struggle for existence and the survival of the fittest to survive.

Life is competition

  • Competition is not only the life of trade, it is the trade of life—peaceful when food abounds, violent when the mouths outrun the food.
  • Co-operation is real, and increases with social development, but mostly because it is a tool and form of competition; we co-operate in our group—our family, community, club, church, party, “race,” or nation—in order to strengthen our group in its competition with other groups.
  • We are acquisitive, greedy, and pugnacious because our blood remembers millenniums through which our forebears had to chase and fight and kill in order to survive, and had to eat to their gastric capacity for fear they should not soon capture another feast.
  • War is a nation’s way of eating.

Life is selection

  • In the competition for food or mates or power some organisms succeed and some fail.
  • In the struggle for existence some individuals are better equipped than others to meet the tests of survival.
  • We are all born unfree and unequal: subject to our physical and psychological heredity, and to the customs and traditions of our group; diversely endowed in health and strength, in mental capacity and qualities of character.
  • Nature loves difference as the necessary material of selection and evolution.
  • Inequality is not only natural and inborn, it grows with the complexity of civilization.
  • Hereditary inequalities breed social and artificial inequalities; every invention or discovery is made or seized by the exceptional individual, and makes the strong stronger, the weak relatively weaker, than before.
  • Economic development specializes functions, differentiates abilities, and makes men unequally valuable to their group.
  • Nature smiles at the union of freedom and equality in our utopias. For freedom and equality are sworn and everlasting enemies, and when one prevails the other dies. Leave men free, and their natural inequalities will multiply almost geometrically.
  • Utopias of equality are biologically doomed, and the best that the amiable philosopher can hope for is an approximate equality of legal justice and educational opportunity.
  • A society in which all potential abilities are allowed to develop and function will have a survival advantage in the competition of groups.

Life must breed

  • Nature has no use for organisms, variations, or groups that cannot reproduce abundantly. She has a passion for quantity as prerequisite to the selection of quality.
  • She is more interested in the species than in the individual, and makes little difference between civilization and barbarism.

Character

  • Society is founded not on the ideals but on the nature of man, and the constitution of man rewrites the constitutions of states.
  • The Greeks of Plato’s time behaved very much like the French of modern centuries; and the Romans behaved like the English. Means and instrumentalities change; motives and ends remain the same: to act or rest, to acquire or give, to fight or retreat, to seek association or privacy, to mate or reject, to offer or resent parental care.
  • Nor does human nature alter as between classes: by and large the poor have the same impulses as the rich, with only less opportunity or skill to implement them.
  • Evolution in man during recorded time has been social rather than biological: it has proceeded not by heritable variations in the species, but mostly by economic, political, intellectual, and moral innovation transmitted to individuals and generations by imitation, custom, or education.
  • Here the initiative individual—the “great man,” the “hero,” the “genius”—regains his place as a formative force in history. He is not quite the god that Carlyle described; he grows out of his time and land, and is the product and symbol of events as well as their agent and voice; without some situation requiring a new response his new ideas would be untimely and impracticable.
  • When he is a hero of action, the demands of his position and the exaltation of crisis develop and inflate him to such magnitude and powers as would in normal times have remained potential and untapped. But he is not merely an effect. Events take place through him as well as around him; his ideas and decisions enter vitally into the course of history.
  • As submissive natures unite with masterful individuals to make the order and operation of a society, so the imitative majority follows the innovating minority, and this follows the originative individual, in adapting new responses to the demands of environment or survival. History in the large is the conflict of minorities; the majority applauds the victor and supplies the human material of social experiment.
  • No one man, however brilliant or well-informed, can come in one lifetime to such fullness of understanding as to safely judge and dismiss the customs or institutions of his society, for these are the wisdom of generations after centuries of experiment in the laboratory of history.
  • It is good that new ideas should be heard, for the sake of the few that can be used; but it is also good that new ideas should be compelled to go through the mill of objection, opposition, and contumely; this is the trial heat which innovations must survive before being allowed to enter the human race.
  • It is good that the old should resist the young, and that the young should prod the old; out of this tension, as out of the strife of the sexes and the classes, comes a creative tensile strength, a stimulated development, a secret and basic unity and movement of the whole.

Morals

  • A little knowledge of history stresses the variability of moral codes, and concludes that they are negligible because they differ in time and place, and sometimes contradict each other.
  • A larger knowledge stresses the universality of moral codes, and concludes to their necessity. Moral codes differ because they adjust themselves to historical and environmental conditions.
  • If we divide economic history into three stages—hunting, agriculture, industry—we may expect that the moral code of one stage will be changed in the next.
  • Man’s sins may be the relics of his rise rather than the stigmata of his fall.
  • History offers some consolation by reminding us that sin has flourished in every age.
  • We must remind ourselves again that history as usually written is quite different from history as usually lived: the historian records the exceptional because it is interesting—because it is exceptional. If all those individuals who had no Boswell had found their numerically proportionate place in the pages of historians we should have a duller but juster view of the past and of man.
  • Behind the red façade of war and politics, misfortune and poverty, adultery and divorce, murder and suicide, were millions of orderly homes, devoted marriages, men and women kindly and affectionate, troubled and happy with children.

Religion

  • Even the skeptical historian develops a humble respect for religion, since he sees it functioning, and seemingly indispensable, in every land and age. To the unhappy, the suffering, the bereaved, the old, it has brought supernatural comforts valued by millions of souls as more precious than any natural aid.
  • For since the natural inequality of men dooms many of us to poverty or defeat, some supernatural hope may be the sole alternative to despair. Destroy that hope, and class war is intensified.
  • Religion does not seem at first to have had any connection with morals. Apparently (for we are merely guessing, or echoing Petronius, who echoed Lucretius) “it was fear that first made the gods”—fear of hidden forces in the earth, rivers, oceans, trees, winds, and sky.
  • Only when priests used these fears and rituals to support morality and law did religion become a force vital and rival to the state.
  • Does history support a belief in God? If by God we mean not the creative vitality of nature but a supreme being intelligent and benevolent, the answer must be a reluctant negative. Like other departments of biology, history remains at bottom a natural selection of the fittest individuals and groups in a struggle wherein goodness receives no favors, misfortunes abound, and the final test is the ability to survive.
  • Add to the crimes, wars, and cruelties of man the earthquakes, storms, tornadoes, pestilences, tidal waves, and other “acts of God” that periodically desolate human and animal life, and the total evidence suggests either a blind or an impartial fatality, with incidental and apparently haphazard scenes to which we subjectively ascribe order, splendor, beauty, or sublimity.
  • If history supports any theology this would be a dualism like the Zoroastrian or Manichaean: a good spirit and an evil spirit battling for control of the universe and men’s souls. These faiths and Christianity (which is essentially Manichaean) assured their followers that the good spirit would win in the end; but of this consummation history offers no guarantee.
  • Nature and history do not agree with our conceptions of good and bad; they define good as that which survives, and bad as that which goes under; and the universe has no prejudice in favor of Christ as against Genghis Khan.
  • One lesson of history is that religion has many lives, and a habit of resurrection. Ikhnaton used all the powers of a pharaoh to destroy the religion of Amon; within a year of Ikhnaton’s death the religion of Amon was restored. Atheism ran wild in the India of Buddha’s youth, and Buddha himself founded a religion without a god; after his death Buddhism developed a complex theology including gods, saints, and hell.
  • “As long as there is poverty there will be gods.”

Economics

  • At the other end of the scale history reports that “the men who can manage men manage the men who can manage only things, and the men who can manage money manage all.”
  • So the bankers, watching the trends in agriculture, industry, and trade, inviting and directing the flow of capital, putting our money doubly and trebly to work, controlling loans and interest and enterprise, running great risks to make great gains, rise to the top of the economic pyramid.
  • From the Medici of Florence and the Fuggers of Augsburg to the Rothschilds of Paris and London and the Morgans of New York, bankers have sat in the councils of governments, financing wars and popes, and occasionally sparking a revolution. Perhaps it is one secret of their power that, having studied the fluctuations of prices, they know that history is inflationary, and that money is the last thing a wise man will hoard.
  • The experience of the past leaves little doubt that every economic system must sooner or later rely upon some form of the profit motive to stir individuals and groups to productivity.
  • Since practical ability differs from person to person, the majority of such abilities, in nearly all societies, is gathered in a minority of men. The concentration of wealth is a natural result of this concentration of ability, and regularly recurs in history.
  • The rate of concentration varies (other factors being equal) with the economic freedom permitted by morals and the laws. Despotism may for a time retard the concentration; democracy, allowing the most liberty, accelerates it.
  • We conclude that the concentration of wealth is natural and inevitable, and is periodically alleviated by violent or peaceable partial redistribution. In this view all economic history is the slow heartbeat of the social organism, a vast systole and diastole of concentrating wealth and compulsive recirculation.

Socialism

  • The struggle of socialism against capitalism is part of the historic rhythm in the concentration and dispersion of wealth.
  • The capitalist, of course, has fulfilled a creative function in history: he has gathered the savings of the people into productive capital by the promise of dividends or interest; he has financed the mechanization of industry and agriculture, and the rationalization of distribution; and the result has been such a flow of goods from producer to consumer as history has never seen before.
  • In free enterprise the spur of competition and the zeal and zest of ownership arouse the productiveness and inventiveness of men; nearly every economic ability sooner or later finds its niche and reward in the shuffle of talents and the natural selection of skills.
  • Competition compels the capitalist to exhaustive labor, and his products to ever-rising excellence.
  • There is much truth in such claims today, but they do not explain why history so resounds with protests and revolts against the abuses of industrial mastery, price manipulation, business chicanery, and irresponsible wealth. These abuses must be hoary with age, for there have been socialistic experiments in a dozen countries and centuries.
  • Socialism in Russia is now restoring individualistic motives to give its system greater productive stimulus, and to allow its people more physical and intellectual liberty. Meanwhile capitalism undergoes a correlative process of limiting individualistic acquisition by semi-socialistic legislation and the redistribution of wealth through the “welfare state.”
  • The fear of capitalism has compelled socialism to widen freedom, and the fear of socialism has compelled capitalism to increase equality. East is West and West is East, and soon the twain will meet.

Government

  • Since men love freedom, and the freedom of individuals in society requires some regulation of conduct, the first condition of freedom is its limitation; make it absolute and it dies in chaos.
  • So the prime task of government is to establish order; organized central force is the sole alternative to incalculable and disruptive force in private hands.
  • Power naturally converges to a center, for it is ineffective when divided, diluted, and spread.
  • Monarchy seems to be the most natural kind of government, since it applies to the group the authority of the father in a family or of the chieftain in a warrior band.
  • All in all, monarchy has had a middling record. Its wars of succession brought mankind as much evil as the continuity or “legitimacy” of the monarchy brought good. When it is hereditary it is likely to be more prolific of stupidity, nepotism, irresponsibility, and extravagance than of nobility or statesmanship.
  • Hence most governments have been oligarchies—ruled by a minority, chosen either by birth, as in aristocracies, or by a religious organization, as in theocracies, or by wealth, as in democracies.
  • It is unnatural (as even Rousseau saw) for a majority to rule, for a majority can seldom be organized for united and specific action, and a minority can.
  • If the majority of abilities is contained in a minority of men, minority government is as inevitable as the concentration of wealth; the majority can do no more than periodically throw out one minority and set up another.
  • So the services of aristocracy did not save it when it monopolized privilege and power too narrowly, when it oppressed the people with selfish and myopic exploitation, when it retarded the growth of the nation by a blind addiction to ancestral ways, when it consumed the men and resources of the state in the lordly sport of dynastic or territorial wars. Then the excluded banded together in wild revolt; the new rich combined with the poor against obstruction and stagnation; the guillotine cut off a thousand noble heads; and democracy took its turn in the misgovernment of mankind.
  • Does history justify revolutions? This is an old debate.
  • In some cases outworn and inflexible institutions seem to require violent overthrow, as in Russia in 1917. But in most instances the effects achieved by the revolution would apparently have come without it through the gradual compulsion of economic developments.
  • Since wealth is an order and procedure of production and exchange rather than an accumulation of (mostly perishable) goods, and is a trust (the “credit system”) in men and institutions rather than in the intrinsic value of paper money or checks, violent revolutions do not so much redistribute wealth as destroy it.
  • There may be a redivision of the land, but the natural inequality of men soon re-creates an inequality of possessions and privileges, and raises to power a new minority with essentially the same instincts as in the old.
  • The only real revolution is in the enlightenment of the mind and the improvement of character, the only real emancipation is individual, and the only real revolutionists are philosophers and saints.
  • Democracy is the most difficult of all forms of government, since it requires the widest spread of intelligence, and we forgot to make ourselves intelligent when we made ourselves sovereign. Education has spread, but intelligence is perpetually retarded by the fertility of the simple.
  • However, ignorance is not long enthroned, for it lends itself to manipulation by the forces that mold public opinion.
  • It may be true, as Lincoln supposed, that “you can’t fool all the people all the time,” but you can fool enough of them to rule a large country.
  • All deductions having been made, democracy has done less harm, and more good, than any other form of government. It gave to human existence a zest and camaraderie that outweighed its pitfalls and defects. It gave to thought and science and enterprise the freedom essential to their operation and growth. It broke down the walls of privilege and class, and in each generation it raised up ability from every rank and place. Under its stimulus Athens and Rome became the most creative cities in history, and America in two centuries has provided abundance for an unprecedentedly large proportion of its population.
  • For this is the vital truth beneath its catchwords: that though men cannot be equal, their access to education and opportunity can be made more nearly equal. The rights of man are not rights to office and power, but the rights of entry into every avenue that may nourish and test a man’s fitness for office and power.

War

  • War is one of the constants of history, and has not diminished with civilization or democracy.
  • We have acknowledged war as at present the ultimate form of competition and natural selection in the human species.
  • The causes of war are the same as the causes of competition among individuals: acquisitiveness, pugnacity, and pride; the desire for food, land, materials, fuels, mastery.
  • The state has our instincts without our restraints.
  • The individual submits to restraints laid upon him by morals and laws, and agrees to replace combat with conference, because the state guarantees him basic protection in his life, property, and legal rights.
  • The state itself acknowledges no substantial restraints, either because it is strong enough to defy any interference with its will or because there is no superstate to offer it basic protection, and no international law or moral code wielding effective force.
  • In the present inadequacy of international law and sentiment a nation must be ready at any moment to defend itself; and when its essential interests are involved it must be allowed to use any means it considers necessary to its survival.

Progress

  • Against this panorama of nations, morals, and religions rising and falling, the idea of progress finds itself in dubious shape. Is it only the vain and traditional boast of each “modern” generation?
  • Since we have admitted no substantial change in man’s nature during historic times, all technological advances will have to be written off as merely new means of achieving old ends—the acquisition of goods, the pursuit of one sex by the other (or by the same), the overcoming of competition, the fighting of wars.
  • One of the discouraging discoveries of our disillusioning century is that science is neutral: it will kill for us as readily as it will heal, and will destroy for us more readily than it can build.
  • We frolic in our emancipation from theology, but have we developed a natural ethic—a moral code independent of religion—strong enough to keep our instincts of acquisition, pugnacity, and sex from debasing our civilisation into a mire of greed, crime, and promiscuity?
  • Have we really outgrown intolerance, or merely transferred it from religious to national, ideological, or racial hostilities?
  • Have we given ourselves more freedom than our intelligence can digest?
  • Has there been any progress at all in philosophy since Confucius? Or in literature since Aeschylus? Are we sure that our music, with its complex forms and powerful orchestras, is more profound than Palestrina, or more musical and inspiring than the monodie airs that medieval Arabs sang to the strumming of their simple instruments?
  • How does our contemporary architecture—bold, original, and impressive as it is—compare with the temples of ancient Egypt or Greece, or our sculpture with the statues of Chephren and Hermes, or our bas-reliefs with those of Persepolis or the Parthenon, or our paintings with those of the van Eycks or Holbein?
  • History is so indifferently rich that a case for almost any conclusion from it can be made by a selection of instances.
  • But perhaps we should first define what progress means to us. If it means increase in happiness its case is lost almost at first sight. Our capacity for fretting is endless, and no matter how many difficulties we surmount, how many ideals we realize, we shall always find an excuse for being magnificently miserable; there is a stealthy pleasure in rejecting mankind or the universe as unworthy of our approval.
  • Is a more objective definition possible? We shall here define progress as the increasing control of the environment by life. It is a test that may hold for the lowliest organism as well as for man.
  • We must not demand of progress that it should be continuous or universal. Obviously there are retrogressions, just as there are periods of failure, fatigue, and rest in a developing individual; if the present stage is an advance in control of the environment, progress is real.

And finally, the purpose of history

History is, above all else, the creation and recording of that heritage; progress is its increasing abundance, preservation, transmission, and use.

To those of us who study history not merely as a warning reminder of man’s follies and crimes, but also as an encouraging remembrance of generative souls, the past ceases to be a depressing chamber of horrors; it becomes a celestial city, a spacious country of the mind, wherein a thousand saints, statesmen, inventors, scientists, poets, artists, musicians, lovers, and philosophers still live and speak, teach and carve and sing.
