“A truth is not necessary, because we negatively are not able to conceive the actual existence of the opposite thereof;but a truth is necessary when we positively are able to apprehend that the negation thereof includes an inevitable contradiction. It is not that that we can see how the opposite comes to be true, but it is that the opposite can not possibly be true.”
