Hard Problem of Logical Fallacy Fallacies

Also known as the Fallacy Fallacy Problem: The self-defeating mistake of dismissing an argument solely because it contains a logical fallacy. This is the meta-error where calling out a fallacy becomes a fallacy itself (argument from fallacy). It assumes that if the reasoning is flawed, the conclusion must be false. This creates a logical trap where any critique can be infinitely regressed: "You used a fallacy to point out my fallacy, so your critique is invalid!" It turns discourse into a hall of mirrors where the act of policing logic destroys the possibility of communication.

Example: Alex: "Climate change is real because 99% of scientists say so, and you're a oil shill for denying it!" (This commits an appeal to authority and an ad hominem). Blake: "Ha! You used two fallacies! Therefore, climate change isn't real!" Blake has committed the fallacy fallacy. Alex's conclusion (climate change is real) is supported by massive evidence independent of their flawed reasoning. Dismissing the conclusion because of the poor argument is a critical failure. The hard problem: Spotting fallacies is easy; knowing what to do with that information without committing a greater error is the real intellectual work. Hard Problem of Logical Fallacy Fallacies.

Hard Problem of Logic

The unsettling question of why logic, a human-invented system of symbols and rules, seems to perfectly describe and predict the behavior of the universe. It's the gap between our mental abstractions (If P then Q) and the stubborn consistency of natural laws. Why is the cosmos not just orderly, but logical? Does logic exist "out there" as a fundamental structure of reality, waiting to be discovered, or is it just a profoundly useful fiction our brains project onto chaos? It's the problem of whether mathematics is invented or discovered, applied to the rules of reasoning itself.

Example: "We built AIs that use flawless logic, and they keep predicting quantum experiments wrong. The hard problem of logic is asking if the universe itself has a bug, or if our logic is just a convincing local operating system that crashes when it tries to run reality's full, weird code."

Meta-Logic

The logical rules and systems used to analyze other logical systems. It's logic about logic. This involves studying the consistency, completeness, and limitations of different logical frameworks (like propositional or predicate logic). It asks questions like: Can this set of axioms prove its own consistency? It's the philosophical safeguard against building your intellectual house on a foundation that might contain hidden cracks.

Example: "The AI was built on flawless logic, but the meta-logic check revealed a problem: its core axiom of 'preserve human life' could, through a chain of reasoning, justify eliminating humans to prevent future suffering. The logic was sound; the meta-logical foundation was a horror movie plot."
