Moral Theology. Charles J. Callan
eats meat. Caius doubts whether attendance at a certain school will do harm to the religion of his son. Balba doubts whether she is bound to inquire about the truth of her sect. As long as their serious doubts remain, these persons should follow the safer course;
(c) when there is question of the validity or invalidity of a Sacrament, for the virtue of religion requires that the Sacraments be administered with fidelity, and be not exposed to the peril of nullity. Example: It is not lawful to consecrate matter that has probably been substantially adulterated;
(d) when there is question of some temporal good or evil to oneself or another, and one is certainly obliged to promote the former or prevent the latter. Examples: Caius suspects that a drink before him is deadly poison; Titus suspects that an object at which he is preparing to shoot is a human being. Neither may disregard his suspicion, even if its contrary is more probable, because the safer side must here be taken. The Fifth Commandment forbids one needlessly to imperil one's own or another's life.
679. In emergency one may expose a Sacrament to nullity by taking a course that is less safe for the Sacrament, but safer for the subject, relying on the axiom that the Sacraments are for men, and not men for the Sacraments. Example: Titus is called to baptize the dying Caius. No water can be procured except rose water, whose sufficiency is doubtful. Titus not only may, but should, use the doubtful matter, since no other can be had.
680. Laxism.—The extreme opposite of Tutiorism is Laxism, whose principle is: "When one is undecided between the safer and the less safe, one may choose the less safe, if it is only slightly or uncertainly probable," because whatever seems at all probable may be prudently followed, and so forms a certain conscience. Example: According to Laxism, one would be justified in following an opinion, because it was defended by one theologian, even though he was of little authority.
681. This system has been condemned by the Church for the following reasons:
(a) It is contrary to the teaching of the Gospels and of the Fathers, which requires one to observe the laws of God with understanding and diligence;
(b) It leads to corruption of morals. The Laxists of the seventeenth century were called in derision those "who take away the sins of the world," and it was against their loose teachings that Pascal inveighed;
(c) Its argument is of no value, for no prudent person would feel that he should follow what was only slightly above the improbable, or that a law should be deemed uncertain because an opinion of uncertain probability could be quoted against it.
682. 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."
683. Probabiliorism.—The arguments in favor of Probabiliorism are as follows:
(a) extrinsic or from authority. This system is more ancient, and, when the controversy over systems began in the seventeenth century, this was the one that was most favored by the Church and theologians;
(b) intrinsic and direct. An essential note of certitude is that it should exclude all doubt, for as long as doubt remains there is only opinion. But one who is undecided cannot exclude all doubt, unless the arguments against the doubts not only balance, but outweigh the latter (i.e., unless one has greater probability on one's side). Hence, he who acts against the safer, which is always certain enough, when his own opinion is not more probable, acts with an uncertain conscience;
(c) intrinsic and indirect. In all other matters a man is not prudent if he assents to that which is less safe and less probable. Thus, in things speculative no scholar would think of accepting a theory which to his knowledge was further removed from the truth; in things practical no man of common sense would prefer a road that seemed less likely to lead to his destination. But we should not be less prudent about the good than we are about the true and the useful. Hence, in doubt we should always decide in favor of the law, unless the arguments for liberty are more convincing.
684. The answers given to the above arguments are:
(a) Probabiliorism is not more ancient as a system, since none of the moral systems were formulated before the sixteenth century; if Patristic and medieval authorities can be quoted who decided cases probabilioristically, others who were contemporary can be named who decided according to milder principles. Moreover, the passages cited are frequently obscure, and do not necessarily bear a Probabilioristic sense. That Probabiliorism enjoyed more favor at the beginning of the controversy is not wonderful, since other systems were more or less identified with Laxism, and the question at issue had not been studied thoroughly. Today Probabiliorism has few defenders.
(b) That which is more probable by far, or most probable, does overcome all doubt, and is even speculatively certain; but he who would require the more probable in this sense does not differ from the Tutiorists spoken of above. That which is more probable, but not to a notable extent, does not exclude all doubt, for the very definition of the more probable is "that judgment which appears more likely to be true than another, but which does not exclude all fear that the other may be true." Hence, if Probabiliorism calls for the notably more probable, it does not differ from Tutiorism; if it calls for the moderately more probable, it wrongly claims that there is no probability on the opposite side.
(c) The true is that which is in harmony with facts, the useful that which conduces to the obtaining of an end, the good that which is in conformity with law. Certainly, a man is not a prudent seeker of truth if he arbitrarily prefers the less to the more true-seeming, nor a prudent seeker of the useful if he chooses the less safe way of obtaining what is a necessary end; but a man can be a prudent seeker of the good, even though he prefers the less safe and less probable, when the law itself, the norm of good, does not demand more from him. Hence, one who makes a judgment according to the anti-Probabiliorist systems does not feel that he is yielding assent to what is speculatively less probable; but that he is making a decision that is practically certain; not that he is choosing a perilous way, but one that is absolutely safe.
685. Arguments against Probabiliorism.—(a) Theoretical Objection.—The principle of Probabiliorism that it is lawful to act against the safer side when the less safe side is more probable, cannot be justified except on the ground that invincible ignorance of obligation exists, and hence that the law does not oblige. But the same argument can be used in favor of milder systems; for even if the less safe side is only probable, it makes one invincibly ignorant that one is obliged. Hence, the basis of Probabiliorism is fatal to its own claims.
(b) Practical Objection.—A system for the direction of conscience should be so simple that it can be easily applied in the everyday affairs of life. Abstract questions may receive attention from moralists for days and months, but concrete cases have to be decided as a rule without delay. But Probabiliorism is such a complicated system that it is unsuited to everyday life. St. Alphonsus declares that he found by the experience of many years that this system cannot be profitably used in the guidance of souls, for it imposes an intolerable burden on both confessors and penitents. And how few are so skilled as to be able to decide quickly, without scruples, and correctly about the relative degrees of probability in opposite opinions!
686. Answers of the Probabiliorists.—(a) A probable opinion against the existence of obligation does not create invincible ignorance, but only doubt; nor does
