The argument from fallacy is a logical fallacy which assumes that because a fallacious argument has been put forward for something it must be false.
Examples:
- Anne: "All cats are animals. Ginger is an animal. This means Ginger is a cat.". Bill: "Ah you just committed the affirming the consequent logical fallacy. Sorry, you are wrong, which means that Ginger is not a cat". But of course, while it is not certain that Ginger is a cat, it might be.
- Bill: "OK - I'll prove I'm English - I speak English so that proves it". Anne: "But Americans speak English too. You have committed the package deal fallacy, speaking English and being English don't always go together. That means you are not English".
