In spite of all this, it may happen that all our pains and inquiries do not lead us to certainty, that solid reasons are found both for and against the existence of an obligation: under these circumstances, a conscientious man will naturally ask whether he must consider himself bound by the law or whether he can, by further reflections -- reflex principles, as they are called -- come to the plain conclusion that there is no obligation either to do or to omit the act in question. Were we obliged to consider ourselves bound in every doubt, the result, obviously, would be an intolerable severity. But since before performing an action the final verdict of our conscience must be free from doubt, the necessity of removing in one way or another such doubts as may have arisen, is self-evident.

In Roman Catholic moral theology, a distinction is recognised between "direct principles" and "reflex principles". Reflex principles are presumptions to be applied in cases of doubt, such as the rule that where the moral right to something is unclear one favours the person in possession. (See Catholic Probabilism.) Such principles are widely found in Western legal systems. The Roman Catholic view of probabilism[1] is that in the absence of certainty – particularly in the case of moral judgments – probability is the best criterion. ...

This view gained vigour and persistence from the teaching of St. Alphonsus, who began his theological career as a Probabiliorist, subsequently defended Probabilism, especially in a treatise entitled Dissertatio scholastico-moralis pro usu moderato opinionis probabilis in concursu probabilioris (1749, 1755), and finally embraced Æquiprobabilism about 1762. In a new dissertation he laid down the two propositions that it is lawful to act on the less safe opinion, when it is equally probable with the safe opinion, and that it is not lawful to follow the less safe opinion when the safe opinion is notably and certainly more probable. In the sixth edition (1767) of his Moral Theology he again expressed these views and indeed towards the end of his life frequently declared that he was not a Probabilist. Saint Alphonsus may refer to the following Roman Catholic saints: St. ...
