Pessimistic Meta-Induction from the History of Science. The gist is this: because even the most seemingly bulletproof scientific theories of times past eventually proved wrong, we must assume that today’s theories will someday prove wrong as well. And what goes for science goes in general—for politics, economics, technology, law, religion, medicine, child-rearing, education. No matter the domain of life, one generation’s verities so often become the next generation’s falsehoods that we might as well have a Pessimistic Meta-Induction from the History of Everything.
