Logical Fallacies in Deductive Arguments Excerpted from http://www.sirius-education.org/courses/syg2000/ SYG2000-E2-LO/Thinking%20About%20Thinking%20and%20Logical %20FallaciesQA%20rtf.rtf There are many rules for manipulating the statements in a syllogism. These rules are the calculus of logic, and they are very similar to the kinds of rules you encounter in a math class. An in-depth discussion of these rules is well beyond the scope of this book, so we will limit ourselves to some simple, intuitive examples of valid and invalid arguments. We begin with some examples of deductive arguments in the form of a Conditional or Hypothetical Syllogism. These syllogisms contain statements that take an if-then form. For example, the statement “If I get a raise, then I will be happy” is a conditional statement. Being happy depends on getting a raise. Conditional syllogisms can also contain statements that place things in categories (categorical statements). The statement “Daisies are flowers” places daisies in the category “flowers.”
