Logic Can Be Fun - Or Can It?	Bradd	10/31/05
Read the following sentence. "This statement is a lie". Is the sentence a lie or not a lie? If it's a lie, then the sentence is not a lie. If it's not a lie, then the sentence is a lie. True or false, in place of lie, works too.
Clarification/Follow-up by Bradd on 10/31/05 6:28 pm: slight correction: for the quibblers - change "sentence" to "statement" - avoiding problems. Actually, either way is ok, but.........you know. Quibblers and all.

There are two types of arguments, deductive and inductive. A deductive argument is valid when the conclusion must be true if the premises are true. When the conclusion does not necessarily follow from the premises, a deductive argument is invalid. In an inductive argument, the conclusion is more or less probably true on the basis of the premises. Because the conclusion does not follow necessarily from the premises, an inductive argument is not usually deductively valid. An inductive argument may be correct or incorrect.
