The Logical Fallacy of Appeal to Anonymous Authority occurs when the source of an authority is not mentioned. All appeal to authority as a final word is fallacious unless the authority cannot be wrong. The fallacy of appeal to anonymous authority uses words like, "a wise person once said," "scholars tell us," "scientists say," "it has been said." If the source is unimportant to what is being said, then this is not a logical fallacy. Appeal to authority is usually not valid anyway unless the authority is God. This is a fallacy of missing information that makes it more difficult to evaluate a claim.
"Science says there is no God."
"It is agreed that only the natural, material world exists. There is no spiritual realm."
