APPEAL TO THE STONE
You’ll NEVER hear this logical fallacy brought up in internet “philosophy debate”. Why? Look at it: It’s used ALL the time!
_Argumentum ad lapidem (English: “appeal to the stone”) is a logical fallacy that consists in dismissing a statement as absurd, invalid, or incorrect, without giving proof of its absurdity_
Example:
Speaker A: Infectious diseases are caused by microbes.
Speaker B: What a ridiculous idea!
Speaker A: How so?
Speaker B: It’s obviously ridiculous.
