insane, I shall prove to you that I am normal; if you should try to prove me normal, I shall prove to you that I am insane. You will say that it is forbidden to steal, kill and deceive because it is immoral and criminal, and I will demonstrate that one may kill and plunder and that it is very moral. And you will think and speak, and I will think and speak, and we all shall be right, and none of us shall be right. Where is the judge who can decide between us and find the truth?
You have one formidable advantage which confers upon you the possession of truth: you did not commit a crime, you are not under judgment, and you have been invited, with substantial fees, to investigate my psychic condition. Ergo, I am insane. On the other hand, if you had been placed in confinement here, Professor Derzhembitzky, and I had been invited to observe you, then you would have been the madman and I the privileged bird—an expert, a liar, who differs from other liars only in that he lies not otherwise than under oath.
