Q1010Rechargeable lithium-ion cells combine high energy density with repeated charging, which is why they sit inside phones, laptops and electric vehicles. They also bring hard questions about mining, safety, recycling and supply chains. Modern mobility depends not only on processors and motors, but on where energy can be stored.
Q1011Modern happiness often means pleasure or life satisfaction, but eudaimonia points towards living well over time. It asks about character, purpose, friendship, excellence and the shape of a whole life. This matters globally because a good life cannot be reduced to mood tracking. The lesson: fulfilment is built, not merely felt.
Q1013A custom, instinct or outcome can be described accurately and still require a separate moral argument. Hume saw that people often smuggle values into facts and then pretend the conclusion was automatic. Evidence matters, but the value judgement has to be named.
Q1014The phrase became famous in debates about education, character and human nature. It highlights the force of environment, but genes, biology and development also matter. This matters globally because societies build schools, laws and expectations around beliefs about change. The lesson: people are shaped, but not from nothing.
Q1015Filled with strange plants and diagrams, it has defeated codebreakers for over a century — and may be an elaborate hoax or a lost language.
Q1016Mary Ann Evans chose George Eliot in a literary culture that often narrowed women writers before reading them. The pen name gave her authority, ambiguity and protection. It does not hide the talent so much as expose the gate it had to pass through.
Q1017Compiled by his colleagues after his death, it preserved 18 plays — including Macbeth and The Tempest — that were never printed in his lifetime.
Q1025Humility is part of intelligence. The honest boundary of knowledge is what makes learning possible.
Q1027Mill argues that conviction needs friction. A belief grows stronger when it has faced the best objections against it.
Q1028Bacon gives three tools for thought: reading gathers material, conversation tests it, and writing makes it precise.
Q1029Aristotle treats flourishing as a whole pattern of life, not a lucky moment or a single success.
Q1030A tiny image of constant renewal: even what looks repeated is never exactly the same.
Q1032Socrates presents reflection not as luxury, but as the condition for a genuinely human life.
Q1041Wilde makes failure elegant without softening it: a mistake becomes useful only when it teaches you.
Q1044This is genuine Melville — from 'Hawthorne and His Mosses' (1850), the essay he wrote in white heat after reading Nathaniel Hawthorne, published in The Literary World. Melville was defending American writers against the pressure to imitate English models. A year later he finished Moby-Dick: a book that failed commercially in exactly the original way he had praised, and became immortal for it.
Q1045Blake suggests that perception itself is the veil. Change the seeing, and the world changes shape.
Q1059Jefferson looks forward without dismissing memory: the past teaches, but the future still asks to be imagined.
Q1060Adams said this while defending British soldiers after the Boston Massacre in 1770. The case was politically explosive, but his point was legal and civic: a jury must follow evidence, not anger, rumour or public pressure.
Q1066A genuine East African proverb, best known in Swahili: 'Wapiganapo tembo nyasi huumia' — when elephants fight, the grass gets hurt. It has become a fixture of diplomacy and political commentary, quoted from African parliaments to the UN, because the mechanism never retires: when the powerful collide, the bill is delivered to those underfoot.
Q1068A saying widely shared in the Native American tradition. It captures a hard truth about willful blindness: someone who is genuinely asleep can be woken, but someone only pretending will never stir, however loudly you call. When ignorance is a choice rather than a gap, no amount of proof reaches it.
Q1070A classic Chinese proverb, praising the humble reliability of writing something down. Even the faintest line of ink outlasts the sharpest memory, because memory is alive — and living things drift, blur and quietly rewrite themselves. What you record, you can trust to stay put.
Q1071A saying from the Chinese proverb tradition. Books hold knowledge, but a living, thinking person can do something a book cannot: aim exactly the right question at exactly your situation. One good conversation with someone wise can shortcut weeks of solitary study.
Q1072Knowledge from books and knowledge from life are not always the same; both matter, but experience has scars.
Q1076The proverb treats vision as social oxygen: without shared direction, a people begins to scatter.
