Logic

August 6th Fact-of-the-Day

Logic is a study of sound reasoning that focuses on a study of arguments. An argument is a series of statements called premises that lead to a conclusion. However, many people who haven't made a formal study of logic are surprised to learn that any argument with a conclusion that follows logically from the premises is a valid argument, even if the conclusion is known to be untrue. Consider this argument for example: Premise 1: All politicians are honest. Premise 2: Politicians never make mistakes. Conclusion: We can always trust politicians. Most people would say that argument is untrue. However, the argument is true, because the conclusion is consistent with the premises. It isn't the argument that is untrue. It is the premises that are untrue. In the field of logic, that argument is true, but it would be called an unsound argument, because it is based on untrue premises. ©2005 Martek International All rights reserved.
