Fooled by Logic Theory

A framework revealing how logic itself can mislead—by treating formal validity as truth, by ignoring the premises that logic takes for granted, and by applying logical rules outside their domain of applicability. Fooled by Logic Theory shows how logical arguments can be perfectly valid and perfectly false, how the appearance of logic can conceal substantive error, and how logic worship can become a form of irrationality. We are fooled when we treat logic as a truth machine rather than a consistency engine.
Fooled by Logic Theory "The argument was logically valid—perfect form, flawless deduction. The premises were wrong. Fooled by Logic: mistaking validity for truth, form for substance. Logic did its job; we failed at ours. We were fooled by the beauty of the argument into missing its falsity."
