Judge me by my sanity, do you? Hmmph.

Allow me to state that I am insane. A truly insane person would not think themselves insane, so as I have just stated that I am insane, it stands to reason that I am not insane. However, by disproving my insanity, I deny that I am insane, so the possibilty still remains that I am indeed insane. A person can either be sane or insane, there is no other alternative because if one is not sane, by definition they are insane. If one is not insane, by definition they are sane. If one declares themslves to be of one state, they add evidence that they are of the opposite state, because an insane person cannot recognize that they are insane. Because of this, I simply cannot judge my own sanity. If I were to ask you to judge my sanity, I could neither agree nor disagree with you because to do so would be to judge my own sanity, which is impossible. Due to my inability to ascertain the soundness of your judgment, I would then not be of sound judgment, and by definition, would be insane. However, I would then be forced to recognize my own insanity, thereby disproving that I am insane. As a result, not only is it impossible for me to judge my own sanity, neither can anyone else. Because this is irrefutible logic, if anyone should think that they could judge my sanity, they would not be of sound reason and almost certainly be insane. Because some may not recognize this, as an outside observer I can with certainty determine the sanity of anyone else.

In other words, no one has any right or reason to call me insane, yet I have every right and reason to call other people insane, because this is irrefutible logic.

(I came up with this while holding a conversation with an imaginary psychiatrist, BTW.)
