After thinking better of my sarcastic tone to Carrol's message. Let me explain. A tautology is a statement that is true by definition. That is, it is always true. A = A is a tautology. A = B is not a tautology. That is, it might be false. Similarly all true statements are not tautologies. I.e., A = B might be true. If all statements were tautologies, math and logic would be very easy. Anything you write down would be true. No need to prove anything. -- Rod Hay [EMAIL PROTECTED] The History of Economic Thought Archive http://socserv2.mcmaster.ca/~econ/ugcm/3ll3/index.html Batoche Books http://Batoche.co-ltd.net/ 52 Eby Street South Kitchener, Ontario N2G 3L1 Canada
