ISCI 1A24 Lecture Notes - Lecture 1: No True Scotsman, Ad Hominem, Argument From Analogy
Document Summary
No true scotsman individual attempts to avoid being associated with an unpleasant act by asserting that no true member of their group would do such a thing. Slippery slope states that a relatively small first step leads to a chain of related events culminating in some significant effect. Ad hominem personal attack against opponent instead of the point that the opposite group makes. Tu quoque attempts to discredit opponent by assenting opponent"s failure to act consistently in accordance with that position. Appeal to emotion manipulates recipient"s emotions rather than implementing valid logic. Argument from incredulity relies on a lack of imagination from the audience. Straw man misrepresentation of the topic of the argument, to assume a weaker version of opponent"s argument and tear it down. Begging the question conclusion you attempt to prove is included in the initial premises of the argument. Appeal to authority someone with authority makes the same argument, so it must be true.
