Document Summary

Fallacies: certain types of defective arguments happen so frequently that they have been given names. These are known as fallacies, and such arguments are said to be fallacious or erroneous. Fallacy: an error in reason: they seem plausible, as they are psychologically persuasive, but it"s important to remember that they are logically powerless. Why study fallacies: we study fallacies because we need to be able to detect them. These arguments fail as they reject a claim based on whose it comes from, not on its merit: the fallacy of composition: arguing what is true of parts of something must be true of the whole thing. The basic pattern is to make a claim and couple it with a completely irrelevant claim that seem to support it, but are in fact just mere distractions: faulty analogy: An analogy draws a comparison between two or more things.
