Does the law of excluded middle apply to the principle of identity and non contradiction?
So is the law of non contradiction. As propositions they are subject to the law of identity respectively. They are not the same propositions, but both are subject to the laws of identity. Thus the law of excluded middle requires one to be negated, thus a law being negated.
