Informal Fallacies - Chapters 9, 10 and 11

Fallacies (def) - "an unreliable inference"(p.245 Rudinow and Barry) A fallacy is an error in reasoning. Plato,
deserves credit for being the first philosopher to collect examples of bad reasoning. In Plato's
Euthydemus Plato
presents a series of fallacious arguments (in dialogue form) and puts the examples of these fallacies into the
"mouths" of two sophists. (Euthydemus and Dionysodorus
) Aristotle, in his book On Sophistical Refutations (the text is available for download)
catalogues forms of incorrect reasoning. He was the first philosopher to do so. We have already discussed the
formal fallacies associated with unreliable conclusions. The formal fallacies focused on the structure of the
argument. How the argument was "put together". (Refer to the analogy of the house, chapter 6 on the web page)
