"From principles is derived probability, but truth or certainty is obtained only from facts"
About this Quote
The line lands because it smuggles a dramatist’s bias into an epistemological claim. Theatre is built on premises - a setup, a worldview, a character’s code - but it cashes out in particulars: the look on someone’s face, the incriminating letter, the body on the floor. Stoppard’s work repeatedly stages the collision between elegant systems and stubborn evidence, whether that’s the slipperiness of history, the seductions of philosophy, or the way intelligence can become a form of self-deception. The subtext is a warning to the brilliant: your framework may be internally consistent and still wrong.
There’s a political edge, too. Principles are how societies justify what they already want to do; facts are the inconvenient audit. Stoppard isn’t dismissing principles as useless - probability matters in science, law, and daily life. He’s insisting on a hierarchy: principles can orient you, but they can’t certify you. Certainty is earned the hard way, by contact with the world.
