Philosophy Anna Donovan Chapter 1 Section 1.6 Validity * What makes an argument good or bad? * What is a Valid argument? * When is an argument invalid? * What is a counterexample? * What is the informal test of validity? * The validity and soundness of an argument determine if it is good or bad * A Valid argument is an argument whose conclusion cannot possibly be false, assuming that the premises are true. * If the premises are true, the conclusion must be true as well. * It does NOT matter if the premises are actually true. EX: 1. Everyone born in France can speak French 2. Barack Obama was born in France 3. Therefore, Barak Obama can speak French
This is a valid argument because assuming the premises are true (even though they aren’t), the conclusion must be true, and the conclusion follows the premises.
