But what kind of reasoning is on solid ground when we’re talking about logic... outside of math? Saying logic here is almost lying to ourselves because we’re not expecting anyone to create logical chains of reasoning.
Do mathematicians even use logic as a reasoning tool, as opposed to a proving tool?
- bitshiftfaced 6y agoIsn't that exactly the question that informal logical fallacies seek to address? I don't think you can just throw away the word "logic" like that. We try to make arguments using deduction and inference, so there is a logical structure behind them. It's just that it isn't as well-defined and doesn't have the mathematical rigor of formal logic.

Formal methods weren't even widespread until late in mathematical history, yet somehow we had mathematical productivity. Mathematicians can scarcely describe their own thinking process, and proving is often the last step to mathematical reasoning. Talking about logical fallacy in ordinary conversation is backward.
