CRITICAL THINKING EXTRA CREDIT PART 1

• Invent an argument with a true premise and a true conclusion that has the following form:

P and Q

Therefore P

(Notice premise one is NOT an if…then statement.  So instead you have a first part + and + the second part.  The conclusion is a simple statement with no connective).

• Invent 2 more arguments of this form, the first with a false premise and true conclusion, and the second with a false premise and a false conclusion.

• Can you invent an argument in the above form that has a true premise and a false conclusion?

• Consider this invalid argument: P and Q

Therefore P and R

(Again, there is NO if….then statement, both the premise and conclusion are and statements.)

Invent 4 arguments with this form, the first having a true premise and a true conclusion, the second a false premise and a true conclusion, the third a false premise and false conclusion, and finally one with a true premise and false conclusion.
