The Epistemology of Scientific Models and the Realism Debate
Quick fact
Scientific models often contain deliberately false assumptions—like frictionless planes or point masses—yet they can deliver highly accurate predictions, which raises a puzzle: how can a false model give true knowledge? This puzzle is central to the realism debate.
Why this is interesting
When you draw a map, you omit most roads—yet you still find your way. Scientists do the same with models, but they then claim to know what the real terrain is like. How can a simplified, false picture yield true knowledge?
