Philosophen haben schon oft “anhand zwingender Logik bewiesen”, dass Dinge unmöglich sind, die sich später als möglich herausgestellt haben, oder vice versa.
Ich zitiere Yudkowsky, weil der Punkt so wichtig ist (Hervorhebungen von mir):
…And so Bob’s careful philosophical reasoning ended up around as useful as Kant’s conclusion that space, by its very nature, was flat. Turned out, Kant was just reproducing an invisible assumption built into how his parietal cortex was modeling space. Kant’s imaginings were evidence only about his imagination – grist for cognitive science, not physics.
Be careful not to underestimate, through benefit of hindsight, how surprising it would seem, a priori, that you could perfectly identify two particles through experiment. Be careful not to underestimate how entirely and perfectly reasonable Bob’s analysis would have seemed, if you didn’t have quantum assumptions to contrast to classical ones.
Experiments tell us things about the nature of reality which you just plain wouldn’t expect from a priori reasoning. Experiments falsify assumptions we can’t even see. Experiments tell us how to do things that seem logically impossible. Experiments deliver surprises from blind spots we don’t even know exist.
Bear this in mind, the next time you’re wondering whether mere empirical science might have something totally unexpected to say about some impossible-seeming philosophical question.
