A fatally flawed argument is one from which nothing can be salvaged. Given that all arguments seek to establish something, an argument which is fatally flawed has such critical [[problems]] with its structure, premises, [[reasoning]], or any combination of these that it is simply [[impossible]] to rework the argument to be [[effective]]. This can be contrasted with [[flawed]] arguments, which require structural reworking, and [[unsound]] arguments, which are based on incorrect [[premise|premises]].
A classic example of a fatally flawed argument is the [[ontological argument]]. Due to [[equivocation]] between an [[existent]] [[God]] and a [[conceptual]] God, the argument is flawed. However, due to its [[syllogism|syllogistic]] and [[analytic]], strong [[deductive]] nature, it is impossible to represent the anything recognisable as the ontological argument in a new form, and the flaw is fatal.
