VALID AND INVALID SYLLOGISMS
Assignment: Write one valid and one invalid syllogism for each type of argument discussed in the text
(categorical, disjunctive, and conditional). That’s a total of six syllogisms. Clearly label the type each syllogism
INVALID CATEGORICAL SYLLOGISM
MAJOR PREMISE: Whatever you put for the major premise.
BE SURE TO INCLUDE THE CAPITALIZED HEADINGS FOR EACH TYPE OF SYLLOGISM AND
EACH PART OF THE SYLLOGISMS.
Each syllogism must be original, which means it is not the same, or nearly the same, as an example used in
the readings, in class activities, in the web tutorial, or presented to you in some other class. It can be an argument
that was actually made by someone else, or one that you make up. Each syllogism must be realistic, which means
If you use examples that actually happened you will probably need to fill in missing portions, because
people rarely talk or write in complete syllogisms.
This assignment must be typed or computer printed. Write each syllogism in a major premise, minor
premise, conclusion order and double space between each part. See the tentative schedule for the date this
assignment is due.
