Ancient Greece · 470–399 BC
Socrates
“How do I know what is truly right?”
Socrates walked around Athens asking simple questions — ‘What is courage?’, ‘What is justice?’ — until people realized they couldn't really explain things they thought they knew. He said the wisest person is the one who knows how much they DON'T know. He annoyed powerful people and was sentenced to death, but died true to his ideas.
“The only true wisdom is in knowing you know nothing.”
The big idea
Socrates believed wisdom begins with admitting how little you know. Instead of lecturing, he asked relentless questions to expose lazy thinking and help people find truth for themselves — the famous ‘Socratic method.’ He also thought no one does wrong on purpose; bad actions come from not truly understanding what is good.
What they changed
He turned philosophy away from ‘what is the universe made of?’ toward ‘how should a human being live?’ — making ethics and self-examination central. The Socratic method is still how lawyers, teachers, and scientists test ideas today.
The controversy
Athens put him on trial for ‘corrupting the youth’ and not believing in the city's gods, and sentenced him to death by drinking poison hemlock. He could have fled, but chose to die rather than betray his principles — becoming history's most famous martyr for free thought.
In their words
- “The unexamined life is not worth living.” — Socrates
- “I cannot teach anybody anything. I can only make them think.” — Socrates
✦ A curious detail
Socrates never wrote a single book — everything we know about him was written down by his student, Plato.
