Prologue:
In response to requests from my logically-sound readers, you can now find links to Logic 101 (which covers the basic structure of logical arguments) and Logic 103 (which covers the Argumentum ad Populum , Argumentum ad Verecundiam, Petitio Principii, Complex Question, The Ignoratio Elenchi, Fallacies of Ambiguity, The Fallacy of Composition , and Fallacy of Division) here.
Begin Actual Article:
In the first article in this series, Logic 101, we looked at the basic structure of a logical argument. We went over what a logical ARGUMENT is (as differentiated from where you are screaming epithets at your spouse and the neighbors start banging on the floor), what a PROPOSITION is (hint: this is not the same thing as the pick up line you offer to the pretty goth girl in the corner, though in my experience it may get you farther), what PREMISES and CONCLUSIONS are. We also went over the two basic kinds of logical arguments: DEDUCTIVE and INDUCTIVE, how they work, and (in the comment thread) why some folks think inductive reasoning sucks.
Now, as promised, I present to you part two: The Attack of the Evil Fallacies
