"John Maynard Keynes (1883–1946) is the latest in a line of great British economists who had a profound influence on the discipline of economics. (...) In listing “the” classic of each of these great economists, historians will cite the General Theory as Keynes’s pathbreaking contribution. Yet, in my opinion, Keynes would belong in this line even if the General Theory had never been published. Indeed, I am one of a small minority of professional economists who regard his Tract on Monetary Reform (1923), not the General Theory, as his best book in economics. Even after sixty-five years, it is not only well worth reading but continues to have a major influence on economic policy."
"There was nothing in these views to repel a student; or to make Keynes attractive. Keynes had nothing to offer those of us who had sat at the feet of Simons, Mints, Knight, and Viner."
"For handling problems such as those facing the British or French treasuries during the war, there are no miracle men. Either current earnings from exports, salable assets, loans or credits... or gold exist for paying foreign suppliers, in which case the officials are a success. Or these assets do not exist, in which case those involved are a failure. However, nothing comes so easily to the press and public mind as the vision of financial genius. Both wish to believe that... there are individuals of transcendental insight and power, men who can make something out of nothing. In Britain during the war (and after) the popular imagination settled on the thirty-one-year-old (in 1914) Treasury official, John Maynard Keynes. His papers of the period, recently published, suggest that he was a hard-working, competent and resourceful man who matched resources to payments with attention and skill and who extended his mind to the similar problems of the French and the Russians. That was all."
"Keynes was a homosexual and had no intention of having children. We are not dead in the long run... our children are our progeny. It is the economic ideals of Keynes that have gotten us into the problems of today"
"John Maynard Keynes first raised the question of what can be done to stabilize the economy when it has fallen into a liquidity trap-when interest rates have fallen to a level below which they cannot be driven by further monetary expansion-and whether monetary policy can be effective at all under such circumstances. Long treated as a mere theoretical curiosity, Keynes's question now appears to be one of urgent practical importance, but one with which theorists have become unfamiliar."
"We can say that around Keynes, around the economic interventionist policy perfected between 1930 and 1960, immediately before and after the war, all these interventions have brought about what we can call a crisis of liberalism, and this crisis manifests itself in a number of re-evaluations, re-appraisals, and new projects in the art of government which were formulated immediately before and after the war in Germany, and which are presently being formulated in America."
"Keynes was chief economic adviser to the British government and largely responsible for keeping the British economy afloat at a time when more than half of our gross national product, and all of our foreign exchange, was being spent on the war. ...I was lucky to be present at one of his rare appearances in Cambridge, when he gave a lecture with the title "Newton, the Man." …Four years later he died of heart failure, precipitated by overwork and the hardships of crossing the Atlantic repeatedly in slow propeller-driven airplanes under wartime conditions."
"Keynes, it has been stressed, is not a radical. He wanted to reform capitalism in order to make it work better and to preserve it. How is it possible that any capitalist could object to a policy of the preservation of capitalism? The answer is that many capitalists are unaware of the precarious state of the system during a period of serious depression, and do not see the proper relationship between their own position and that of the system as a whole. It is inevitable that most of the effective measures listed in the full-employment legislation above will be strongly opposed by some group of the capitalist population."
"Keynes never sought to change the world out of any sense of personal dissatisfaction or discontent. Marx swore that the bourgeoisie would suffer for his poverty and his carbuncles. Keynes experienced neither poverty or boils. For him the world was excellent."
"For Keynes unemployment could never be a "natural" disaster, like an earthquake or a flood. He knew that it is a failure of social and economic organization, a failure by society and social institutions to achieve a desirable goal. Quite simply, when millions of people are out of work, we have failed to organize our society so that full employment is secured. And being a problem of social organization, there must be a solution if only society is willing to take the steps necessary. This doesn't mean that either finding or implementing a solution will be easy. Our society and our economy are complicated institutions, linking a multitude of firms and people at home and abroad, each with their own goals and their ways of doing things. Moreover, achieving full employment may conflict with other goals we consider to be important. But it is irrational simply to accept unemployment, as if it were a fact of nature. Unemployment is our failure. At the very least, we must spell out clearly the choices that must be made if we are to attain full employment."
"I was lucky to hear the economist John Maynard Keynes, a few years before his death, give a lecture about the physicist Isaac Newton. Keynes was at that time himself a legendary figure, gravely ill and carrying a heavy responsibility as economic adviser to Winston Churchill. He had snatched a few hours from his official duties to pursue his hobby of studying Newton's unpublished manuscripts. Newton had kept his early writings hidden away until the end of his life in a big box, where they remained until quite recently. Keynes was speaking in the same old building where Newton had lived and worked 270 years earlier. In an ancient, dark, cold room, draped with wartime blackout curtains, a small audience crowded around the patch of light under which the exhausted figure of Keynes was huddled. He spoke with passionate intensity, made even more impressive by the pallor of his face and the gloom of the surroundings."
"We're all Keynesians now."
"The great service of Keynes to recent history is that we now know, in the way that governments did not know in the 1930s, how full employment can be maintained."
"The belief that monetary instability--inflation and deflation--is the principal, or at least a principal, cause of other economic evils; the hope that sound monetary principles can be identified and, when identified, would greatly diminish uncertainty and risk; the focus on the job of the public sector being to provide the private economy with a stable measuring-rod and a stable environment--all these are core ideas of whatever we choose to call monetarism. Keynes believed these ideas very, very strongly in the mid-1920s. And his Tract on Monetary Reform is a review of economic theory and a look at the economic problems of post-WWI Europe through this set of monetarist spectacles."
"I can tell you — I was helping when Britain was trying to get a loan from the United States immediately after the war, and I was talking to one of Keynes's assistants. And Keynes came in the room and walked over to us and the man I was talking to us said, "This is Coase, who is helping us with the statistics. I don't think you know him." And Keynes said, "No, I don't." And walked off. And that's my life with Keynes."
"What do you think of J. M. Keynes's book? ... The condemnation of the work of the Conference as a whole is none too severe. I remember few cases in history where negotiators might have done so much good, and have done so much evil."
"In a book which gained a vast publicity, particularly in the United States, he exposed and denounced "a Carthaginian Peace." He showed in successive chapters of unanswerable good sense the monstrous character of the financial and economic clauses. On all these matters his opinion is good. Carried away, however, by his natural indignation at the economic terms which were to be solemnly enacted, lie wrapped the whole structure of the Peace Treaties in one common condemnation. His qualifications to speak on the economic aspects were indisputable; but on the other and vastly more important side of the problem he could judge no better than many others."
"No one embodied the Cambridge spirit of culture, fun, and public duty so much as Maynard Keynes. No one was more brilliant or charming. No economist in this century influenced politicians or the course of economics more."
"Keynes’s central concerns for his own time ring true today. He was worried about the fragility of our collective prosperity, and the grave tensions between nationalism and the rootless cosmopolitan attitudes underpinning a peaceful and flourishing global society. He focused on how to organize our activities and use our prosperity to create a world fit for the good life. He sought to expose the bankruptcy of ascendant ideological nostrums: laissez-faire, spontaneous order, collective cooperation, central planning. And he thought deeply about the technocratic problems of economic management – and about the social, moral, and political disasters that would follow from failing to address them."
"Why does Camelot lie in ruins? Intellectual error of monumental proportion has been made, and not exclusively by the politicians. Error also lies squarely with the economists. The "academic scribbler" who must bear substantial responsibility is Lord Keynes..."
"Keynes did not believe that political freedom and economic efficiency, for which he hoped, would suffice to bring about a better world. It was also necessary to guarantee social justice. The problem of articulating between these various ends is far from being satisfactorily resolved. In his tireless search for a solution to this challenge, Keynes figures among the great humanists and social thinkers whose work merit closer understanding and meditation. For Keynes, the problems of poverty, inequality, unemployment and economic crises are neither exogenous accidents nor punishments for excess, but rather the result of a poorly organized society and human error. It is these up to individuals united in the polis to attenuate or end them by carrying out major reforms. Are such reforms possible within the context of the capitalist economies known to us today? Keynes believed or at least hoped they were. The setting up of the Welfare State seemed to prove him right, but the tide has turned and his diagnosis of capitalism's state of health, put forward now more than half a century ago, is more relevant than ever. No one can claim to know what the future holds. It is up to us, however, to construct it. This is perhaps the main message of John Maynard Keynes."
"Keynes is largely responsible for elevating employment (and/or output) to a position as an explicit objective for policy. As I have emphasized, Keynes sought to change the basic perception of the economic process; he sought to bring employment, as such, onto center stage as a variable subject to direct manipulation. He sought to overthrow the classical model of market equilibrium in which employment is determined only as an emergent result or consequence of the interaction among the demand and supply choices made by market participants. Once again in this respect, Keynes was too persuasive. By elevating full employment to explicit consideration as a policy target, and thereby generating neglect of both monetary and market institutions, the Keynesian emphasis ensured the eventual stagflation that we experienced in the 1970s. The scenario might have been quite different if the Keynesian effort had been recognized for what it was rather than for what it was not."
"I liked him, but not much; he smelled of Bloomsbury... He seethed at "the Carthaginian peace of M. Clemenceau", thought the treaty [of Versailles] an offence comparable with the German invasion of Belgium, and blasted "the policy of reducing Germany to servitude for a generation..." From the start he got everything out of focus, even imagining that "the perils of the future lie not in frontiers and sovereignties but in food, coal and transport". ... He condemned the liberated states, and scouted further danger to France in measurable future... The poor chap's prophecies went all agley... "Those who sign this Treaty," said the Chief German Delegate, "will sign the death sentence of many millions of German men, women and children". And Keynes echoed him: "I know of no adequate answer to these words". Others were more imaginative. Ten years after signature European production surpassed pre-war levels, and standards of life were never higher. In Germany coal, iron and steel beat all records, savings increased hugely, national income was 60% higher than before the war... Small attention should therefore have been paid to Keynes' outburst or to the fits of ungovernable silliness which it incited. The outcome was however prodigious, for the book [The Economic Consequences of the Peace] was just what American dissidents needed to reject Wilson. It was used to prove by "the horrors of Versailles"... Keynes took the first step in reasoning the United States back into neutrality between good and evil."
"The central message is still that, as Keynes argued, fiscal policy is the answer to liquidity traps, financial or political. The arguments against fiscal policy in Japan, so far as I understand them are intellectually fallacious; they would receive failing grades in an undergraduate macro exam."
"Keynes, I am sure, often interpreted his role as that of the prophet and the politician, and it was in such a period, I presume, that he once wrote: "Words are to be a little wild, for they are the assaults of thoughts on the unthinking." I do not challenge this for prophets and politicians, for they have special occupational license to promote their objectives free from stodgy inhibitions on the exercise of all their rhetorical resources for persuasion. I believe in the virtues of professional division of labor, however, and I am troubled, therefore, when economists adopt the role and the tactics of the prophet or the politician, especially when there is any ground for suspicion that what is involved is false prophecy."
"There is a nice story which is rather revealing about the power of Keynes's arguments and their political content. It is about John Strachey, a Marxist. He was a cousin of Lytton Strachey ― they both had the same skill in writing. John Strachey wrote a book called The Coming Struggle for Power. In the 1930s this book was so influential in Cambridge, England, that, when I got there, every person had it on his bookshelf, prominently displayed. It was an exciting book, intellectually exciting to read. It was the Bible of Cambridge students. In my last year at Cambridge Strachey was invited by the Marshall Society, which was the general undergraduate society for economics student, to give a talk. In this talk he argued that Marx showed us the way to make the system work, an argument that met a very, very strong favorable response ― as his earlier writing had done. I had been asked in advance to move a vote of thanks at the end of the lecture; say a few words, if I could, about his lecture, but essentially to move a vote of thanks. I did, except I took the occasion to say that there would appear ― this was in November 1935 ― within a few months a book that would set out a superior method of analysis. It had been written by John Maynard Keynes. I didn't know whether Strachey would know the name. He motioned to me and said, "I'd like to thank you for your vote of thanks," and so on; "I'd like to find out more about the book by Keynes." And I told him, and he took down the name. At the time, I did not realize the connection between Keynes and Lytton Strachey and Lytton and John Strachey. A couple of years later I received a new book by John Strachey in the mail from the Left Book Club. I was astounded; it was absolutely Keynes. I mean, he was so much influenced by Keynes ― he had been so strongly influenced by Keynes that he became an instant, overnight, follower. Strachey really understood Keynes; it's a brilliant exposition and application to the British situation. It's rather more interesting than Keynes and deserves to be reprinted. It shows how Keynes had refuted Communism and how John Strachey, an extreme Marxist whose life up to then had been devoted to Marx and the Marxian course, had been completely changed by Keynes. Given that history, the later attacks on U.S. Keynesians, accusing them of being Communists, were incomprehensible to me."
"It wasn't really that they were put into effect as ideas by the New Deal or by anybody else. As a matter of fact, paradoxically, many of the policies of Nazi Germany were very much in line with Keynesian recommendations for overcoming a depression, and the German depression in general was overcome. Hitler's Germany came out of the depression long before the United States did, and that was because they spent a lot of money, deficit financing, controlled investment, on a war program. As a matter of fact, the Great Depression never was over in the United States until the war. The New Deal did not act on Keynesian policies at all. The history of Keynesian theory and policy is full of paradoxes. It is important that you really understand the complexities of the history of the period."
"Keynes did not challenge the efficacy of price adjustment mechanisms in clearing particular markets in the Marshallian partial equilibrium theory on which he had been reared. He did challenge the mindless application of those mechanisms to economy-wide markets. Founding what came to be known as macroeconomics, he was modeling a whole economy as a closed system. He knew he could not use the Marshallian assumption that the clearing of one market could be safely described on the assumption that the rest of the economy was unaffected."
"'Anything we can do, we can afford,' John Maynard Keynes declared in the midst of the Second World War. The pandemic reminded us of that principle; with climate change, the world might hope to actually enact it."
"In ethics Keynes was a Platonist, in politics he was an Aristotelian. His ethics pointed him towards the ideal; his politics towards moderation."
"Keynes saw himself as overturning ‘‘classical’’ economics. He was less revolutionary than he thought. Large chunks of Marshallianism – particularly to do with the importance of time (short and long periods), the technique of partial equilibrium analysis, and the cash balances version of the quantity theory of money – were central to his economics and distanced it from the timeless simultaneous-equation general equilibrium theory of Menger and Walras which Hayek regarded as the supreme achievement of the marginalist revolution."
"Of all economists, Lord Keynes was most sensitive to the conditions of the next moment—he was a Geiger counter of future headlines. This was a most extraordinary gift, and it may have extraordinary consequences for his theories."
"Keynes's economic philosophy is thus made up of three interdependent parts: his technical macroeconomics, his embattled political philosophy and his ultimate ethical purpose."
"The world in which we live today has been made much more secure by the economic wisdom that Keynes brought to us during the dark days of the Great Depression. When that wisdom is partly or wholly ignored in the making of economic policy, large numbers of people are made to suffer unnecessarily. I am afraid we have seen several depressing examples of that in the recent years, especially in Europe, with a huge human toll. Keynes was a great pathfinder, and it would have distressed — if not surprised — him to see how well-identified paths can be comprehensively neglected by policymaking that draws more on ideology than on well-reflected reasoning."
"Like Odysseus, Keynes was a successful, not a tragic, hero. He heard the beautiful singing of the Sirens, but took precautions against being shipwrecked, keeping to the course for which his talents and the state of the world predestined him. Artfully, he strove for the best of all worlds, in his life and his work, and miraculously, came close to achieving it."
"Keynes's habit of treating the state as a deus ex machina to be invoked whenever his human actors, behaving according to the rules of the capitalist game, get themselves into a dilemma from which there is apparently no escape. Naturally, this Olympian interventionist resolves everything in a manner satisfactory to the author and presumably to the audience. The only trouble is — as every Marxist knows — that the state is not a god but one of the actors who has a part to play just like all the other actors."
"On the morning after the German “election” [the Reichstag election of 29 March 1936] I travelled to Basle; it was an exquisite liberation to reach Switzerland. It must have been only a little later that I met Maynard Keynes at some gathering in London. “I do wish you had not written that book”, I found myself saying (meaning The Economic Consequences, which the Germans never ceased to quote) and then longed for the ground to swallow me up. But he said, simply and gently, “So do I.”"
"You must realize how bad, temporarily, capitalism had become in public opinion. I remember seeing a poll of small town attitudes in local newspapers. They asked questions like "should we nationalize the banking system?" More than half of those editors, about the most conservative group in the world, were in favor of nationalizing the banking system. Father Coughlin, the Detroit demagogue who turned anti-Semitic, complained about "fountain pen money, the perpetrator of great wealth, the money changers in the temple." It was kind of a crude expansionism. Huey Long and "every man a millionaire," or whatever it was. So I would say that Keynes thought of himself as saving the system. And lots of the New Dealers ― original New Dealers, Veblenites, technocrats ― did not like Keynesian economics. They said "that is using palliatives, it's not getting rid of the wicked capitalistic ethos." Keynes told Roosevelt when he came here in 1933 that he needed to spend so much more per month in deficit spending. He gave very precise figures with great self-confidence."
"An optimist who lived at a time when the world economy was running so badly that clever gimmicks could still work wonders, Keynes's object was to save capitalism from itself. In the end, his prescription in its most simple form self-destructed, as the obligation to run a full-employment humanitarian state caused modern economies to succumb to the new disease of stagflation - high inflation along with joblessness and excess capacity. Economists of the most diverse views are constantly asking themselves: What would Keynes advise if he were now alive. And usually - whether the economist is a free-marketeer like Friederick von Hayek or one with strong interventionist leanings like John Kenneth Galbraith - they pay Keynes the supreme compliment of believing that if brought back to earth, Maynard would be favoring just what each of them happens to favor. One also might wonder what Lord Keynes would prescribe for the huge structural deficit of Ronald Reagan, with the crowding out of investment that it implies once the American economy reattains high levels of employment."
"Everyone understands now, on the contrary, that there can be no solution without government. The Keynesian idea is once again accepted that fiscal policy and deficit spending has a major role to play in guiding a market economy. I wish Friedman were still alive so he could witness how his extremism led to the defeat of his own ideas."
"Keynes's intellect was the sharpest and clearest that I have ever known. When I argued with him, I felt that I took my life in my hands, and I seldom emerged without feeling something of a fool. I was sometimes inclined to feel that so much cleverness must be incompatible with depth, but I do not think that this feeling was justified."
"There are still many people in America who regard depressions as acts of God. I think Keynes proved that the responsibility for these occurrences does not rest with Providence."
"Yes, Keynes was a genius. Yes, some of his ideas were inchoate and would not have lent themselves usefully to diagramming and symbolic manipulation. Yes, by the time of the Radcliffe committee many of his British admirers were still frozen in the Model T version of his system. And yes, Keynes resented excessive simplifying of his paradigms. Nevertheless, in science it is not the incoherent, inchoate and ineffable that has a cash value. If that were so, Goethe would be a greater scientist than either Einstein or Newton. What matters is the Kuhnian paradigm that people who are not geniuses can use. That which so many scholars independently agreed upon cannot be independent of the text that Keynes wrote down for them to read. What is remarkable is not the cogency of the case that Leijonhufvud manages to muster, which is rather flimsy, but rather how strong was the latent demand in the 1970s for a work to debunk Keynesianism. Harry Johnson put the same point in a different way."
"Among economists John Maynard Keynes (1883–1946) did well over a lifetime. He had a high I.Q. and must have been a better-than-average bridge player. Apparently some of his triumphs in currency trading stemmed from his micro- and macroeconomic hunches. However, after scoring well on bets that Germany’s postwar inflation would cause the mark to depreciate, he did go virtually bankrupt when for a few months the mark reversed from its down trend. A kindly City friend enabled him to avoid bankruptcy, a fate worse than death in the post-Edwardian Age. (Again in 1929 a number of people incurred losses when a Keynes-Robertson speculative fund did badly. I learned this from Lionel Robbins. However, in autumn 1932, German Professor Hans Neisser heard Keynes give a lecture at Cambridge, in which he said, “Right now is your lifetime opportunity. Borrow and beg to invest in diversified common stocks that are going to recover now that the pound has ceased to be over-valued.” Not a shabby call.)"
"John Maynard Keynes, who died in 1946 at the age of 62, is not only the best known economist of our times but also a man who by any standards must be reckoned as one of the leading personages of the first half of the twentieth century. The history of the era which followed World War I can no more dispense with the name of this singular individual than it can with the names of Einstein, Churchill, Roosevelt, or Hitler. It is only in this broad perspective that Keynes' full importance becomes visible. How ought we to judge the influence of this man? Is he the Copernicus of economics, as so many claim, the man who banished the ghosts of economics grown rigid in the chains of tradition, who opened the door to prosperity and stability? Or did he destroy more than he created and has he summoned into being spirits that today he possibly would be gladly rid of? It is difficult to make a simple answer to these questions. A fair judgment would have to take into account not only the manifold talents and personal charm of the man, but would require also the dissection of issues which have nourished most of the economic controversies of our time and which have given even the experts pause. We may begin by noting a characteristic trait of this animated, impulsive, and artistically sensitive man: his virtuoso-like ability to change positions on important questions, positions which he had only shortly before defended with intelligence and vigor."
"Later economists continued to hew a revisionist line, maintaining absurdly that Keynes was merely a benign pioneer of uncertainty theory (Shackles and Lachmann), or that he was a prophet of the idea that search costs were highly important in the labor market (Clower and Leijonhufvud). None of this is trie. That Keynes was a Keynesian—of that much derided Keynesian system provided by Hicks, Hansen, Samuelson, and Modigliani—is the only explanation that makes any sense of Keynesian economics. Yet Keynes was much more than a Keynesian. Above all, he was the extraordinarily pernicious and malignant figure that we have examined in this chapter: a charming but power-driven statist Machiavelli, who embodied some of the most malevolent trends and institutions of the twentieth century."
"How is it that such an extraordinary man (in the best sense), whose intellect was so wide-ranging and who was just as much artist and organizer as he was scholar, could at the same time be so blind to moral-political postulates (which even in the narrower domain of economics are more important in the long run than clever monetary formulae) without which human society cannot exist? To fully appreciate the kind of man and the kind of philosophy we are here concerned with, it is useful to compare Keynes with Adam Smith. In the depth and extent of their influence at least, the two men were strikingly similar. Moreover, both Smith and Keynes had interests which extended far beyond the confines of economics. But whereas Smith left us, in addition to his magnum opus on the Wealth of Nations (1776) a book on the Theory of Moral Sentiments (1759) which exposes the full moral-philosophical foundations of his much-misconstrued economic doctrines, Keynes has left us, in addition to his economic works, a monograph on the theory of probability (A Treatise on Probability, 1921). For Smith, whose book on the Wealth of Nations was planned as a segment of a giant opus on the cultural history of mankind, economics was viewed as an organic part of the larger whole of the intellectual, moral, and historical life of society; for Keynes, economics was part of a mathematical-mechanical universe. The one man was a representative of the humanist spirit of the 18th century; the other a representative of the geometric spirit of the 20th century; a deistic moralist was the one, an exponent of positivistic scientism the other."
"This seems to me Keynes's important contribution to economics: that he asked a number of very fundamental new questions. He asked what determined the level of employment. He asked whether the economy was inherently stable at the level of full employment, automatically returning to it when disturbed. He asked, as I say, how the rate of interest is determined. These questions remain with us, and will and must remain, central to all economics."
"The consequences of Mr. Keynes's attack upon orthodoxy are very far reaching. First, it cuts the ground from under the pretended justification of inequality, and allows us to see the monstrous absurdity of our social system with a fresh eye."
"Keynes turned the question back again. He started thinking in Ricardo’s terms: output as a whole and why worry about a cup of tea? When you are thinking about output as a whole, relative prices come out in the wash — including the relative price of money and labour. The price level comes into the argument, but it comes in as a complication, not as the main point. If you have had some practice on Ricardo’s bicycle you do not need to stop and ask yourself what to do in a case like that, you just do it. You assume away the complication till you have got the main problem worked out. So Keynes began by getting money prices out of the way. Marshall’s cup of tea dissolved into thin air. But if you cannot use money, what unit of value do you take? A man hour of labour time. It is the most handy and sensible measure of value, so naturally you take it. You do not have to prove anything, you just do it."
