Quote:No I'm aware that was pointed at him I was just asking someone who knows more about fallacies what the actual name of the fallacy is that- just because 1 of a whole is false the other things withing that whole are false and therefore the whole is false... there's got to be a name for it.. I can't find it on my list though.
Oh,in that case,I don't know. Not sure that is necessarily correct as a principle.
I think you may be conflating 'logical' or 'logically valid" with 'true'. Logic does not guarantee truth.In formal logic the premise is always accepted as true for the sake of argument.
An argument may take the form of:
IF A (which is actually true) AND B (which is also actually true) AND C (which is actually untrue)---- then X . The inference will be logically valid but untrue.
Sorry I couldn't help,but it's nice to be asked.
