SYLLOGISM

In philosophy, an argument so arranged that if the first two statements (premise) are accepted the third (conclusion) necessarily follows. In theology, when the first statement is a revealed truth, and the second is a fact or truth knowable by reason, the third is said to be a theological conclusion. Such conclusions are frequently the object of the Church's infallible teaching authority. (Etym. Greek syllogismos, a reckoning together.)
