The Other Systems

The true system of reflex principles will lie between the extremes of Tutiorism and Laxism. As already said, these two doctrines have been censured by the Church; but there are other systems that are moderate, and that are permitted by the Church and defended by theologians. These systems are:

(a) Probabiliorism, whose principle is: “When one is undecided between the safer and the less safe, one may choose the less safc only when it is more probable”;

(b) Equiprobabilism, whose doctrine is: “When one is undecided between the safer and the less safe, one may choose the less safe only when it affirms the non-existence of the law, and is at least equally probable with the opposite”;

(c) Probabilism, whose doctrine is: “When one is undecided between the safer and the less safe, one may choose the less safe whenever it is certainly and solidly probable”;

(d) Compensationism, whose doctrine is: “When one is undecided between the safer and the less safe, one may choose the less safe whenever it is certainly and solidly probable, and there is a proportionate reason to compensate for the risk taken.”
