Argumentum Ab Impossibili Valet Inlege is a Latin phrase that translates to “an argument from the impossible proves nothing.” It refers to a logical fallacy where an argument is based on the premise that something is impossible, therefore concluding that it cannot be true or valid. This fallacy disregards the possibility of exceptions or unknown factors that may challenge the initial assumption. In logical reasoning, it is essential to provide evidence and sound reasoning rather than relying on the impossibility of a situation to support an argument.
