Roman Catholic Archdiocese of Tunis to close down all the Catholic churches in the country, forced the Holy See to accept an agreement of the type known as a modus vivendi, a term that literally means "a way of living". This particular agreement was unofficially described as instead a "modus non moriendi" ("a way of not dying"). By it, all but 5 of the country's more than 70 churches were handed over to the state, including what had been the cathedral of the archdiocese, while the state, for its part, promised that the buildings would be put only to use of public interest consonant with
Modus ponens every proof involving Cut can be transformed (generally, by a constructive method) into a proof without Cut, and hence that Cut is admissible. The Curry–Howard correspondence between proofs and programs relates "modus ponens" to function application: if "f" is a function of type "P" → "Q" and "x" is of type "P", then "f x" is of type "Q". The validity of "modus ponens" in classical two-valued logic can be clearly demonstrated by use of a truth table. In instances of "modus ponens" we assume as premises that "p" → "q" is true and "p" is true. Only one line
