It seems to me that many regular legal documents at least verge on this kind of contradiction. For example, a contract will often contain clauses that specify how and / or under which conditions it may be terminated. An even stranger document is the Power of Attorney, which authorizes a person to represent another person in legal matters, thus at least in part removing legal authority from the issuer. There is also the Lasting Power of Attorney, which grants a person the power to represent another person independently of their future consent to such representation. (These are rarely issued, I suppose.)

To: lit-ideas@xxxxxxxxxxxxx Date: Sunday, May 31, 2009, 12:17 AM What about "the Undersigned hereby promises to undersign no promises" as a performative contradiction? By signing it one promises not to do X and one does X at the same time (X = to undersign a promise). One violates the terms of an agreement or contract by entering into the agreement or contract. Engagement entails violation, or, you make a commitment by breaking it. Richard Henninge University of Mainz
