"Are you familiar with the three basic laws of logic from philosophy `` 101 `` ? 1 . Law of identify . Anything is itself . If a proposition is true , than it is true . 2 . The law of the excluded middle : anything is either A , or not A . A proposition can either be true , or false . 3 . Law of contradiction ( your favorite ! ! ) - nothing can be both A , and not A . A proposition can not be both true , and false . -Mach"
