Fallacies are forms of argumentation that are known to be invalid. A list of common fallacies is described at http://commfaculty.fullerton.edu/rgass/fallacy3211.htm I wondered if there were any fallacies that the Scientology enterprise did not use. As far as I can tell, they make liberal use of all of them. So here is the list of common fallacies with examples taken from arguments that the Scientology enterprise makes in public, or to its clients: The list is too long for one post so I'll post only a few at a time. 1. FAULTY CAUSE: (post hoc ergo propter hoc) mistakes correlation or association for causation, by assuming that because one thing follows another it was caused by the other. example: An SP crossed Babbs' path yesterday and, sure enough, she was involved in an automobile accident later that same afternoon. explanation: Bad things happen randomly, not because of SPs. example: Tom Cruise has had great success in Hollywood after taking more Scientology auditing. explanation: Cruise has natural ability, Scientology had nothing to do with his success. 2. SWEEPING GENERALIZATION: (dicto simpliciter) assumes that what is true of the whole will also be true of the part, or that what is true in most instances will be true in all instances. example: Muffin must be rich because she is OT, and OTs are the richest members of Scientology. explanation: Mostly people who are rich can afford the high costs of OT, but Muffin wasn't rich, she went into deep debt to get to OT. example: David is a wog protester against Scientology and wogs are usually ignorant of Scientology, therefore I can ignore anything David says about it. explanation: Not all wogs are ignorant of Scientology abuses. David has done much research on how the Scientology enterprise hurts people. note: "wog" is a racist term used by the Scientology enterprise to instill hatred of people who are not clients of Scientology. 3. HASTY GENERALIZATION: bases an inference on too small a sample, or on an unrepresentative sample. Often, a single example or instance is used as the basis for a broader generalization. example: All of those wogs are really rude. I asked a few to come in for a personality test, and they told me to get lost. explanation: Some wogs were rude does not mean they all are. example: Clears are actually powerful, important people. My auditor is clear and he runs a successful business! explanation: One clear running a successful business does not mean they all do. 4. FAULTY ANALOGY: (can be literal or figurative) assumes that because two things, events, or situations are alike in some known respects, that they are alike in other unknown respects. example: What's the big deal about utterly ruining a few Scientology critics in order to help Scientology succeed? After all, you can't make an omelet without breaking a few eggs. explanation: Making an omelet is figuratively good, and spreading Scientology is also good. Breaking a few eggs is figuratively bad, and ruining people is bad. But just because you have to do something bad to make an omelet does not mean that you have to do something bad to spread Scientology. example: Punishing Scientology for fraud is like killing Jews in concentration camps. explanation: Punishing Scientology is bad and killing Jews is bad, but just because Jews were innocent victims does not mean that Scientology is one too.
