"If we look at the way the universe behaves, quantum mechanics gives us fundamental, unavoidable indeterminacy, so that alternative histories of the universe can be assigned probability"
About this Quote
The key move is his phrase “alternative histories.” That’s not casual sci-fi flair; it nods to late-20th-century efforts to make quantum mechanics speak about the whole cosmos without smuggling in an external observer. In approaches like consistent/decoherent histories, the universe can be described as a bundle of possible narrative threads, each with probabilities attached. The subtext: physics doesn’t just predict outcomes, it assigns weights to competing “stories” about what happened and what could have happened.
Gell-Mann’s intent is also disciplinary: to domesticate indeterminacy. He’s not celebrating randomness as mystical freedom; he’s insisting it’s structured, calculable, and “unavoidable” precisely because the theory works. It’s a rebuke to deterministic nostalgia and a quiet defense of a modern scientific worldview where certainty is downgraded, not abandoned, and where explanation means managing probabilities rather than declaring fate.
