Argument from ignorance is an informal logical fallacy that asserts that an argument is necessarily true because it has not been proven false or vice versa. Instead of providing evidence to support a claim, the argument simply demonstrates that others cannot provide evidence to the contrary. For example, to say that ghosts exist because no one has proven otherwise would be a case of argumentum ad ignorantiam. Usually trickery, this argument is used in what highly esteemed legal principle? Discuss
