John Maynard Keynes (5 June 1883 – 21 April 1946) was an English economist whose writings form the basis of Keynesian economics; he has been called the "father of macroeconomics." ◦ Originally trained in mathematics, he graduated from King's College, Cambridge in 1904 with a B.A. in mathematics before turning to economics. ◦ He was born in Cambridge to John Neville Keynes, an economist and Cambridge lecturer in moral sciences, and Florence Ada Keynes, a social reformer who became the town's second female mayor. ◦ He was a founding figure of the Bloomsbury Group, won a King's Scholarship to Eton in 1897, took the Tomline Prize for mathematics in 1901, and married the Russian ballerina Lydia Lopokova in 1925. ◦ As chief Treasury representative at the Paris Peace Conference, he walked out in protest in late May 1919 and resigned on June 5. ◦
Keynes argued that aggregate demand determined the overall level of economic activity, and that inadequate aggregate demand could lead to prolonged periods of high unemployment. ◦ He held that since wages and labour costs are rigid downwards, the economy will not automatically rebound to full employment, and he advocated fiscal and monetary policy to counter recessions. ◦ He made the case against passively waiting for markets to self-correct, writing in 1923 that "The long run is a misleading guide to current affairs. In the long run we are all dead." ◦ He believed that most positive decisions are taken as a result of "animal spirits — of a spontaneous urge to action rather than inaction," not as the outcome of a weighted average of quantitative benefits multiplied by quantitative probabilities. ◦ He argued that a large proportion of human activity rests on emotion rather than calculation, and that confidence, not arithmetic, drives investment. ◦ In 1930, he predicted that the standard of life in progressive countries one hundred years hence will be between four and eight times as high as it is to-day, and that the economic problem may be solved within a hundred years. ◦ He foresaw a leisure society in which three-hour shifts or a fifteen-hour week may put off the problem for a great while. ◦ He held a moralist's contempt for the love of money as a possession, calling it a somewhat disgusting morbidity. ◦ He coined the term "technological unemployment" in 1930, framing it as a temporary maladjustment rather than a permanent crisis. ◦ He distrusted "purposiveness," describing the purposive man as always trying to secure a spurious and delusive immortality for his acts by pushing his interest in them forward into time. ◦ He saw the deepest human problem as arriving only after material want is solved: how to use freedom from pressing economic cares to live wisely and agreeably and well. ◦ He warned that an unchecked claim of contract over the common good breeds revolution, arguing that nothing can preserve the integrity of contract between individuals except a discretionary authority in the State to revise what has become intolerable. ◦
Keynes's defining edge was his willingness to reverse himself after being wrong. ◦ After being wiped out in the October 1929 crash, he abandoned top-down macro timing and became a bottom-up contrarian value investor. ◦ He described his central principle of investment as going contrary to general opinion, buying stocks cheap relative to intrinsic value and holding them through thick and thin. ◦ By his own admission he was "a one-armed contrarian" — better at buying value near the bottom than selling at the top — and he died wealthy. ◦
Keynes operated with a mental model in which aggregate demand — total spending in the economy — determines the overall level of economic activity, and inadequate aggregate demand could lead to prolonged periods of high unemployment. ◦ He viewed wages and labour costs as rigid downwards, meaning the economy will not automatically rebound to full employment. ◦ He understood economic decisions through the lens of "animal spirits," a spontaneous urge to action rather than inaction, and held that a large proportion of positive activities depend on spontaneous optimism rather than on a mathematical expectation. ◦ After 1929, his investment mental model shifted to contrarian value: going contrary to general opinion, buying cheap relative to intrinsic value, and holding through thick and thin. ◦ He believed the State must retain discretionary authority to revise contracts that have become intolerable, lest vested interests grow unchecked and half the population become no better than slaves to the other half. ◦ He saw technological unemployment as a temporary maladjustment caused by discovering means of economising labour faster than finding new uses for it. ◦
Keynes was an economist whose central macroeconomic claim, detailed in *The General Theory of Employment, Interest and Money* (1936), held that aggregate demand determines the overall level of economic activity. ◦ He advocated fiscal and monetary policy to counter recessions. ◦ He originally trained in mathematics, graduating from King's College, Cambridge in 1904 with a B.A. in mathematics before turning to economics. ◦ He wrote *A Tract on Monetary Reform* in 1923. ◦ He published *The Economic Consequences of the Peace* in 1919. ◦ He wrote *Economic Possibilities for our Grandchildren* in 1930, in which he coined the term "technological unemployment." ◦
Keynes engaged the world through forceful public campaigning rather than detached theorizing. ◦ Infused with a strong sense of noblesse oblige from his Eton and Cambridge education, he became incensed by high British unemployment and waged a long campaign to provoke the Cabinet into action, arguing forcefully it was the government's duty to fix the problem it had created. ◦ On December 8, 1919, he published *The Economic Consequences of the Peace*, a blistering critique of the Treaty of Versailles, branding the treaty a "Carthaginian Peace" and privately calling President Wilson "the greatest fraud on earth." ◦ His grim prophecy in that work foresaw the catastrophe that punitive reparations would unleash, warning that if we aim at the impoverishment of Central Europe, vengeance will not limp. ◦
A central contradiction in Keynes is the gap between the confident forecaster and the chastened speculator. ◦ In the Roaring Twenties he boasted of predicting the credit cycle and reportedly told a Swiss banker, "There will be no more crashes in our lifetime!" ◦ Two years later, in the October 1929 crash, his portfolio of stocks and commodities was wiped out, and he admitted he had no ability to pick market tops. ◦ He was, by his own admission, "a one-armed contrarian" — better at buying value near the bottom than selling at the top — yet he died wealthy. ◦
To engage Keynes on his own terms is to enter the Keynes–Hayek debate that began in 1931 and still resonates within present-day economic policymaking. ◦ In that debate, Keynes argued that in a slump governments should keep money cheap, cut taxes so people have cash to spend, and as a last resort directly employ the jobless on infrastructure — with any borrowing repaid once everyone is back at work. ◦ He was provoked to action by high unemployment and waged a long campaign to provoke the Cabinet into action, arguing it was the government's duty to fix the problem it had created. ◦

One more check: In Core Philosophy, the sentence "He argued that a large proportion of human activity rests on emotion rather than calculation, and that confidence, not arithmetic, drives investment." — this is a paraphrase of [3]. The fragment says "there is the instability due to the characteristic of human nature that a large proportion of our positive activities depend on spontaneous optimism rather than on a mathematical expectation, whether moral or hedonistic or economic." and "Confidence, not arithmetic, drives investment." The latter is not a verbatim quote from the fragment! Wait, looking at [3]: "Keynes argued that a large proportion of human activity rests on emotion rather than calculation: "there is the instability...". This is the article text. Then it says "Confidence, not arithmetic, drives investment." Is that in the fragment? Let me check the provided text:
"[3] (source: https://en.wikipedia.org/wiki/Animal_spirits_(Keynes)) Keynes argued that a large proportion of human activity rests on emotion rather than calculation: "there is the instability due to the characteristic of human nature that a large proportion of our positive activities depend on spontaneous optimism rather than on a mathematical expectation, whether moral or hedonistic or economic." Confidence, not arithmetic, drives investment."
Ah! "Confidence, not arithmetic, drives investment." is part of the fragment text, not inside the quotes but part of the article's prose. So it is supplied evidence. Good. My sentence paraphrases that. So it's fine.
