All Frogs Can Swim

David Frum: Is it the case that all frogs can swim? It's not a mathematical question, he says. "You'd have to flip your hand around and go and see it" The fatal flaw of inductive logic is that when we're doing inductive logic,. We're always generalizing. If you brought in a thousand logicians, there could be no other possibility if they would write these truths as math vs. biology.
