Q1138The most famous words Galileo probably never said: “Eppur si muove” first appears in print in 1757, over a century after his 1633 trial, where legend claims he muttered it after being forced to recant that the Earth moves. No contemporary account records it. The legend survives because it compresses a truth: recantation extracted by force changes the man's words, not the planet's orbit.
Q1139Not found in Galileo's writings: historians trace the slogan to later summaries of his method (the mathematician Hermann Weyl quoted it as a paraphrase in 1927). It compresses what Galileo genuinely did — timing balls on ramps with water clocks, turning quality into quantity. Modern science lives inside this sentence, whoever wrote it.
Q1140This comes from Newton's 1676 letter to Robert Hooke. In context, the famous 'shoulders of giants' image is about inherited knowledge, rivalry, humility, and the long chain of discovery. Isaac Newton (1643–1727) was an English physicist and mathematician whose laws of motion and gravity founded classical physics.
Q1141Attached to Isaac Newton by long tradition: after losing a fortune in the South Sea Bubble of 1720, he is said to have remarked that he could calculate the motions of heavenly bodies, but not the madness of people. The story surfaces decades later in anecdote collections, so historians treat it cautiously. True or polished, it records something real: Newton did lose about £20,000 — and markets still humble physicists.
Q1142This comes from Descartes's Discourse on the Method. The source context is methodical doubt: remove shaky assumptions until thought finds a firmer starting point. René Descartes (1596–1650) was a French philosopher and mathematician, a father of modern philosophy, famous for 'I think, therefore I am.'
Q1143Not Descartes's wording, though it fairly labels his method. In the Meditations (1641) and the Discourse on Method (1637), Descartes systematically doubted everything that could be doubted — senses, mathematics, the world itself — until he hit the one indubitable fact: doubting is thinking, and thinking proves a thinker. Doubt, used as an instrument rather than a mood, became modern philosophy's founding tool.
Q1144Widely attributed to Voltaire, but not found in his works; researchers class it as a modern saying sheltering under his name. It would not have embarrassed him: Voltaire's whole career — from Candide to his campaigns against injustice — was an argument that the quality of a mind shows in what it asks, since answers can be borrowed but questions reveal where thinking actually lives.
Q1145Genuinely Voltaire: he quoted the Italian proverb “il meglio è l'inimico del bene” in his Dictionnaire philosophique and opened his 1772 poem “La Bégueule” with its French form — “le mieux est l'ennemi du bien.” The insight has since been adopted by engineers and economists alike: chasing a flawless version often destroys a good one that would have worked, shipped and helped.
Q1148Widely attributed to Benjamin Franklin, but absent from his writings — including Poor Richard's Almanack, where hunters have looked hardest. It reads like a Franklin maxim because he manufactured so many of the genuine kind (“Lost time is never found again”). The logic holds regardless: preparation is cheap insurance, and its absence is a plan too — just a bad one.
Q1149These are actually the words of the historian Will Durant, from the Kant chapter of his bestseller The Story of Philosophy (1926); over time the summary was mistaken for the philosopher. (“Science is organized knowledge” alone goes back to Herbert Spencer.) The pairing earns its fame: knowledge can be stacked in libraries, but wisdom only shows up as a well-run life.
Q1150Verbatim Kant: this is the categorical imperative, the centrepiece of his Groundwork of the Metaphysics of Morals (1785). The test it proposes is universalisation — before acting, ask whether you could will everyone in your situation to act the same way. Lying fails the test (universal lying destroys the trust lying depends on). It remains the most influential single sentence in modern moral philosophy.
Q1151This comes from Darwin's On the Origin of Species. The source context is not self-help but natural selection: survival depends on variation, pressure, and changing conditions. Charles Darwin (1809–1882) was an English naturalist whose theory of evolution by natural selection transformed our understanding of life.
Q1152From a letter the young Darwin wrote to his sister Susan in 1836, near the end of the Beagle voyage, later published in The Life and Letters of Charles Darwin (1887). He was quoting a rule he lived by ever after: despite chronic illness that limited him to a few working hours a day, those hours — kept sacred for decades — produced On the Origin of Species.
Q1153Attributed to Nikola Tesla; versions appear in profiles and reminiscences of his later years, when his rivals were rich and he was not. The consolation is the long game: Tesla's alternating-current system does power the modern world, and his name now marks cars, units and craters. Vindication arrived — decades past the deadline.
Q1154Widely attributed to Tesla, but no lecture, article or interview containing it has ever been produced; it belongs to the modern Tesla mythos, where his real genius attracts mystical add-ons. His authentic work needs no embroidery: energy and frequency were precisely what he mastered — the rotating magnetic field, radio-frequency experiments, alternating current itself.
Q1155This comes from The Brothers Karamazov, where Dostoevsky turns faith, guilt, freedom, and responsibility into a family drama with philosophical force. Fyodor Dostoevsky (1821–1881) was a Russian novelist whose works probe morality, faith and the depths of the human mind.
Q1156Widely attributed to Dostoevsky and true to his fiction, though not traced to a specific novel in this exact wording; his The House of the Dead — drawn from his own Siberian imprisonment — circles the same truth. Dostoevsky watched men survive on hope and collapse without it: hope, for him, was not optimism but the oxygen of the soul.
Q1157This comes from Twilight of the Idols, one of Nietzsche's late, sharp works. The source matters because the style is aphoristic: short lines are meant to provoke, not soothe. Friedrich Nietzsche (1844–1900) was a German philosopher known for ideas like the will to power, written in a vivid, aphoristic style.
Q1158This comes from Twilight of the Idols, one of Nietzsche's late, sharp works. The source matters because the style is aphoristic: short lines are meant to provoke, not soothe. Friedrich Nietzsche (1844–1900) was a German philosopher known for ideas like the will to power, written in a vivid, aphoristic style.
Q1159This comes from Thus Spoke Zarathustra, Nietzsche's poetic-philosophical work. The source speaks through image and prophecy, so the line should be read as dramatic thought, not plain advice. Friedrich Nietzsche (1844–1900) was a German philosopher known for ideas like the will to power, written in a vivid, aphoristic style.
Q1161Authentic Dickinson — the complete two-line poem reads: “That it will never come again / Is what makes life so sweet.” Like almost all of her nearly 1,800 poems, it was found in manuscript and published only after her death in 1886. Two lines carry a whole philosophy: scarcity is not the enemy of sweetness but its source.
Q1163This comes from Wilde's essay The Soul of Man under Socialism. The source context is art, individual freedom, and suspicion of social systems that flatten the person. Oscar Wilde (1854–1900) was an Irish poet and playwright famed for his wit, author of 'The Picture of Dorian Gray'.
Q1164A polished popular condensation of the conclusion of Walden (1854), where Thoreau actually wrote: “If one advances confidently in the direction of his dreams, and endeavors to live the life which he has imagined, he will meet with a success unexpected in common hours.” The shortened form appears on posters; the original adds the important part — the success that comes is of an unexpected kind.
Q1166Widely attributed to Goethe, but not found in his German works in this form; scholars suspect it entered English through loose translation of lines in Wilhelm Meister. Goethe lived the principle regardless — poet, novelist, minister of state, amateur scientist — a man constitutionally incapable of leaving knowledge unapplied.
