Talk:Deduction

The second rule listed here is not necessarily true. While the truth of R is dependent on the truth of Q, truth of Q is not dependent on the truth of R. Try this: "If Mike Huckabee is elected President, his wife will be First Lady. Mrs. Huckabee is not first lady, therefore Mike was not elected President." However, there are (logically, anyways) ways in which Mike could be President without Mrs. Huckabee being First Lady - they could get divorced, the position of First Lady could be abolished, what have you. Is therea logician arouns who could clear this up? Walt 23:42, 23 November 2007 (EST)
