Introduction to Logic, Spring 2011 Winterbottom Homework for Monday January 24 th 2011: Print out this paper and write your answers on it. Don't forget to put your name on it. Bring your answers to class (and have them ready at the beginning of class on Monday). 1. In your own words, explain what makes an argument a valid argument? (i.e. explain the concept of validity as it applies to arguments). E.G. An argument is valid if and only if the truth of its premises would guarantee the truth of its conclusion. 2. For the following arguments, note whether the argument is (a) factually correct or factually incorrent, (b) valid or invalid; (c)sound or unsound. Argument I: Premise 1 : Jon is a man Premise 2 : All men are bastards Conclusion : Jon is a bastard Factually incorrect: since premise 2 is false (or so I will suppose here). Valid: if the premises were true, then the conclusion would have to be true. Unsound: since it is factually incorrect.
