Moral Theology Part 29

(c) The principle of possession is applied more strictly in cases of justice; for, since justice implies a more exact equality and a more rigorous right than other virtues (see 154), disputes in matters of justice demand stronger proofs. But every virtue renders to someone his due, and hence there is no reason why principles applicable to justice should not be applicable to other virtues also. The principle of Probabiliorism, likewise, is just as applicable to the court of conscience as to the civil court, since in both courts the aim is to get the truth as nearly as possible.

699. General Arguments Against Equiprobabilism.--(a) Theoretical Objection.--If we judge Equiprobabilism by its arguments, we find it unconvincing, for that which is old in it does not agree with that which is new, and that which is new argues equally well for Probabilism. Thus, the old arguments for Probabiliorism mean in the last a.n.a.lysis that the greater probability deprives the opposite side of all solid probability; logically, then, one should conclude that equal probability deprives both sides of all solid probability, since one neutralizes the other. The new arguments are drawn from the principles that in doubt one should decide in favor of the side in possession, that a doubtful law does not oblige, etc.--all of which principles, as we shall see, favor Probabilism.

(b) Practical Objection.--If we judge Equiprobabilism by its adaptibility for use, we find it wanting. A moral system should be one that can be easily understood and applied, otherwise it is unworkable and useless. But Equiprobabilism is so complicated and abstruse that even the professional theologians who hold it are often at a loss how to apply it, and are found to give inconsistent decisions. How can it be expected, then, that anyone else will be able to decide whether the law or liberty is is possession, whether the degree of probability on one side is greater than or equal to that on the other, whether the question has to do with the existence of the law or its cessation, etc.?

700. Replies of the Equiprobabilists.--(a) The old (i.e., probabilioristic) principles of Equiprobabilism are not contrary to the new. A more probable opinion not only balances the opposition by its equal arguments, and thus puts away doubt, but it also wins a.s.sent by the surplus in its favor, and thus cert.i.tude is had. When the two opposites are equally probable, there is a state of true doubt, but cert.i.tude is had by recourse to the principles of possession and doubtful law. These principles proper to Equiprobabilism do not favor Probabilism, if one is impartial in one's use of them, and willing to use them against as well as for liberty.

(b) Equiprobabilism is not more difficult in its application than Probabilism. It does not require that one determine minutely and exactly the greater or equal probability of the arguments for law and for liberty, or that one devote extraordinary diligence to the solution of the problem. All it requires is that one consider the matter seriously, weigh the arguments on both sides impartially, and decide to the best of one's ability which side appears to be more probable or to have the presumption in its favor.

701. Probabilism.--The meaning of Probabilism can be seen from a comparison with the opposite systems. (a) Unlike Probabiliorism and Equiprobabilism, Probabilism does not require a greater or equal probability, but permits one to follow what is less probable; (b) unlike Laxism, it does not allow one to follow what is only slightly or uncertainly probable, or to apply the system to all cases of doubt.

702. A judgment is probable when it is supported by arguments that make it seem true, although there may remain reasons for doubt. Examples are conclusions based on a.n.a.logy, on hypothesis, on the opinions of others, or on the calculus of probabilities.

703. Probability is of various kinds. (a) It is absolute or relative, according as the supporting reasons are grave, either when considered alone, or when compared with the objections. Even the Probabiliorists admit that an opinion that is merely probable may be followed, if it is solidly probable and there is no argument against it (see 649). (b) We have solid or slight probability, according as the supporting motives are or are not such as would move, if not convince, a prudent man--that is, a man who shows good judgment in most things. (c) We have certain or uncertain probability, according as a person is sure or not, after reasonable consideration, that the arguments seem valid and the opinion likely. (d) Probability is internal or external, according as the arguments are drawn from the matter at issue itself (i.e., from its nature, properties, causes, effects, etc.) or from the authority of the doctors who have defended an opinion.

704. Relative probability according to logicians remains even when a lesser is compared with a greater probability. (a) If the opposing arguments are drawn from different sources, the more probable does not attack the less probable, and hence does not weaken its probability.

Example: An intrinsic argument has more weight than a mere appeal to authority, but it does not attack the opposite argument, and hence does not diminish its probability. (b) If the opposing arguments are drawn from the same source, each one weakens the opposite, since there is direct opposition. But the more probable does not destroy the less probable, since, in spite of the greater appearance of truth on the one side, there still remains room for the possibility that the other side may be true.

705. A moral judgment is solidly probable when the following conditions are present:

(a) For the judgment there must be an intrinsic or extrinsic argument that would be considered weighty by a prudent man. Example: An opinion that has the support of a universally acknowledged authority is strongly probable, whereas, if it has only the support of one obscure writer, it is only slightly probable.

(b) Against the judgment there must be no decisive argument from authority or reason. Example; The judgment that a certain course of action is lawful because St. Alphonsus permits it, is ordinarily solidly probable; it is not probable, however, if the opinion of St.

Alphonsus (e.g., that Catholics may act as sponsors in non-Catholic baptisms) has been disallowed by the Church, or if the argument he uses (e.g., that concerning the amount that const.i.tutes grave matter in theft, which reasons from conditions in his day) is not strong.

(c) The arguments for the judgment must retain their probability, if they are set over against the arguments for the opposite. Manifestly, if the arguments are all satisfactorily answered by the opposite side, the judgment based on them ceases to retain the appearance of truth.

Probabilism does not require, however, that one determine the relative degrees of probability in opposite opinions.

706. It is not sufficient according to the Probabilists that another be certain of the probability of an opinion; but the person who follows the opinion must himself be certain that it is solidly probable.

707. Regarding the kind of authority necessary to make an opinion solidly probable from external evidence, Probabilism teaches:

(a) that absolute probability (that is, such a weight of authority as would appear strong even to the most learned) ought to be estimated by quality rather than quant.i.ty--by the learning, prudence, impartiality, and independent study of the authors, rather than by their numbers. If five distinguished moralists arrive by separate study at the same conclusion (i.e., that an opinion is probable), or if one of special reputation in a matter under question supports the probability of an opinion, the argument from authority is strong;

(b) that relative probability (that is, such a weight of authority as suffices for one who is unlearned, such as a child, a halfwit, an uneducated person) is had sufficiently through the word of only one person who is looked up to as a guide or instructor, such as a parent, confessor, or teacher.

708. Probabilism supposes that one regards the opinion one follows as truly probable, and that one is convinced that it is lawful to follow such an opinion. Hence, the system does not apply in certain cases.

(a) It does not apply to cases in which there is no probability on either side--that is, to cases of negative doubt (see 656 sqq.), whether the doubt be of law or of fact.

(b) Probabilism does not apply to cases in which there is only slight or uncertain probability for the less safe side. Example: Caius has heard that a certain novel opinion is defended by a recent author, but he is uncertain of the author's standing as a theologian, and he realizes that the fact that a man has written a book does not make his ideas solidly probable.

(c) Probabilism does not apply to cases in which there is solid probability for the less safe side, but one doubts whether one can lawfully follow it; for it is always sinful to act with a doubtful conscience (see 641 sqq.). Example: Caius has read in a reliable work of theology that a person in certain circ.u.mstances, which are his own, is probably excused from Ma.s.s. But the word "probably" makes him uncertain whether he can follow this opinion.

709. For the above-mentioned cases, to which their principle does not apply, Probabilists refer to the rules for a doubtful conscience (see 656 sqq.). The following special rules are given for cases of negative doubt:

(a) If the doubt is one of law and insoluble, one is free to act; for it is a general principle that an act may be considered lawful, as long as there is no serious reason to the contrary. Example: Semp.r.o.nius goes out into the country on Sunday afternoon. An opportunity to fish presents itself, but Semp.r.o.nius begins to doubt whether there is or is not a church law against fis.h.i.+ng on Sundays. As no argument for either side is known to him, he may act on the general principle that what is not forbidden is lawful.

(b) If the doubt is one of fact and insoluble, and a prohibitory law is involved, one is free to act; for it is commonly admitted that legislators do not intend their prohibitions, which are restrictions of liberty, to be interpreted with the utmost rigor. Example: t.i.tus is eating a chicken dinner late on Thursday night when his watch stops. As he has no way of discovering the time, he does not know whether Friday or the end of the dinner will arrive first. He may continue the meal, making no undue delays.

(c) If the doubt is one of fact, and a preceptive law is in question, one must take reasonable precautions to settle the doubt; for the lawgiver wills that those who are subject to the law should make use of the ordinary means to learn the facts on which obligation depends (see above, 384). If the doubt remains insoluble, one may decide in favor of liberty; for it may reasonably be presumed that the legislator does not intend to obligate those whose obligation remains uncertain. Example: Caius doubts whether he has reached the age of sixty, when the obligation of fasting ends. He should try to discover his real age; but, if he can find no real proofs either for or against the age of sixty, he may decide in favor of sixty, if there are some indications that he is of that age.

710. The solutions given above for cases of negative doubt suppose that there is no other or higher law that forbids one to take the risk of deciding in favor of liberty. Hence, in the following instances one must decide against liberty:

(a) in negative doubts when the validity of acts is at stake. Example: t.i.tus is uncertain whether the law requires the age of fourteen for a valid contract of marriage; he is also uncertain whether he is fourteen years old. The doubt of law and of fact does not excuse t.i.tus from the law, if he wishes to marry. He must clear up the doubts, and if necessary he must secure a dispensation.

(b) in negative doubts when reasons of charity or justice forbid one to take risks. Example: Caius is uncertain whether he paid Semp.r.o.nius for work done for him. He is bound to make inquiries about the matter.

711. Probabilism cannot be applied, therefore, when the mental state of the subject is doubt, weakly founded opinion, or practical uncertainty.

But, even when one holds an opinion as solidly and certainly probable, one may not follow it as a moral guide, if there is something in the nature of the object or matter itself which forbids this.

(a) A probability of law favoring liberty may not be followed in those matters in which some natural, divine or human law requires one to follow the safer side (see cases enumerated above, 678, 661). Example: The following opinions are probable; that instruction regarding the Trinity and the Incarnation is not indispensable for salvation; that rye-bread is valid matter for the Eucharist. But in practice it would be unlawful to take the risk of following these opinions, except in cases of extreme necessity, when nothing else can be done.

(b) A probability of fact favoring liberty may not be followed so long as there remains nothing more than probability of fact; for, while the will of the lawgiver may on account of probability of non-obligation change one's relation to the law from obligation to non-obligation, it does not change facts. Examples: On Friday t.i.tus doubts whether a dish before him is meat or fish; probably it is meat on account of its appearance, probably it is fish on account of its odor. At night Fr.

Caius is much fatigued, and doubts whether he has said Vespers.

Probably he did not, because he cannot recall what feast will be celebrated tomorrow; probably he did, because he remembers having said Compline.

712. For probabilities of fact, to which as such their system does not apply, Probabilists offer the following solutions:

(a) In certain cases one may take from the doubt of fact its bearing on obligation, by recourse to the manifest will of the legislator as declared in the law itself or expressed through dispensation. Examples: While hearing confessions, Semp.r.o.nius doubts whether his jurisdiction has already expired. He cannot recall the date of expiration, but, thinking the matter over, he sees that probably the date has not arrived. His difficulty is therefore solved, for the Code (Canon 209) supplies jurisdiction in cases of probability of fact. t.i.tus and Caia wish to marry. There is a doubt whether or not they are first cousins, but it seems that probably they are not so related. Their difficulty is solved by obtaining a dispensation.

(b) In other cases one may change the probability of fact into a probability of law by recourse to a probable opinion or argument that under the existing doubt of fact the legislator does not wish the law to oblige. Examples: t.i.tus, who has what is probably lawful food before him, argues with himself that it is not likely that the Church wills to put him to the expense, trouble, and loss of time required to order other food. Fr. t.i.tus, who has probably said Vespers, argues that theologians of authority teach that, when there is a serious reason for thinking one has performed such an obligation, it may be presumed that the Church does not require more.

713. If a case of probability of fact on which obligation hinges cannot be solved by recourse to the expressed or inferred will of the lawgiver, one has no choice but to follow the safer side, for then, though it is probable that a certain thing is a fact, it is not probable that one has a right to act. Example: Semp.r.o.nius, while hunting, sees an object moving in the bushes. The probabilities are that it is not a human being, but it is not probable that Semp.r.o.nius has the right to risk homicide by firing at it.

714. Not all Probabilists use the principle of the presumptive will of the lawgiver for all cases of negative doubt; some employ different principles for different kinds of doubt, and sometimes arrive at other decisions than those given in the preceding paragraphs. Thus, they give such rules as the following:

(a) In negative doubt of law regarding the lawfulness of an act, use the principle that law or liberty should be followed according as one or the other is in possession (see 660). Example: He who has only slight reasons for thinking that a law exists, or that it is of grave obligation, or that it extends to his case, etc., may decide against the law. But he who has only slight reasons for thinking that a law has been abrogated, or that a dispensation has been granted, etc., must decide for obligation.

(b) In negative doubt of law regarding the validity of a past act, use the principle _that what was done is to be held as rightly done_.

Example: He who has no reasons, or only trifling ones, for thinking that a Sacrament was not administered validly or received validly, should decide for validity.

(c) In negative doubts of fact, use the principles that one should judge according to what usually happens, or that facts must not be taken for granted but must be established, or that presumption favors that which has possession. Examples: If there is no good reason to think that a conscientious person gave consent to a temptation, one may decide for the negative, since that would usually be true. If there is no good reason to think that one has made a vow, one may decide for the negative, since the burden of proof is with the other side. If, in a question about fast and abstinence, it is uncertain whether or not a person has reached twenty-one years, or whether Friday has commenced, the presumption is for the negative, since liberty has been in possession; but if it is uncertain whether a person has reached the age of sixty or whether Friday has ended, the presumption is for the negative, since the law has been in possession.

715. Having discussed the cases to which Probabilism is not extended, we pa.s.s on to the cases to which it is applied. Probabilism is used in any and every case where speculative certainty as to what is lawful or unlawful is not had, but where there is only speculative probability against an opposite probability.

(a) Probabilism is used not only in probability of law, but also in probability of fact that can be reduced to probability of law, as was explained above (see 712).

(b) Probabilism is used in probability of law, whether or not the question be about the existence or the cessation of the law. There is probability against existence of law, when one has good reason to think that a law was not made or not promulgated, or that the time when it goes into force has not arrived, or that it does not apply to certain persons or circ.u.mstances, etc.; there is probability for cessation of law, when it is certain that a law did exist, but one has good reason to think that it ceased or was abrogated, that one is excused or dispensed from it.

(c) Probabilism is used in probability of law, whether the law in question be natural, divine or human--that is, in every case of law where invincible ignorance is possible (see 319 sqq., 356).

716. The claim of Probabilism is that, in all the cases given above, he who follows an opinion excusing him from obligation, may act with a practically certain conscience and be free of all moral guilt, if the opinion is theoretically and seriously probable. The arguments for this thesis are of two kinds: (a) extrinsic proofs, from the approval given Probabilism by the Church and the favor it has enjoyed among moralists; (b) intrinsic proofs, from the nature of law and obligation, and the superiority of Probabilism in practice.

717. Extrinsic Arguments.--(a) The Church gave explicit approval to Probabilism by praising the theological works of St. Alphonsus in which Probabilism is defended; she gave and continues to give implicit approval by the freedom she has granted to the teachers of this system from the days of Bartholomew Medina, its first expounder (1527-1581), down to the present. The Church even makes use of the principles of Probabilism in interpreting her own laws, as is evidenced by such rules of law as the following in the Decretals: "Things that are odious should be understood strictly, things that are favorable widely" (Rule 15); "Where the law is doubtful, follow the minimum" (Rule 30); "Where the lawgiver could have spoken more clearly, the interpretation should be against him" (Rule 57); "The kinder interpretation should be given penal laws" (Rule 89).

(b) In the Patristic and medieval periods Probabilism had not been scientifically formulated, but many of the Fathers and early Doctors solved cases probabilistically, and there are not a few pa.s.sages in the great theologians before the sixteenth century which enunciate the same principles as those advocated by Probabilists. When the system was formulated by Medina in 1577, it met with universal favor among Catholic moralists, and, though it suffered an eclipse from the middle of the seventeenth to the middle of the eighteenth century, it has been growing in influence since the days of St. Alphonsus, and appears today to have recovered its former preeminence. Among its adherents are some of the greatest names in the history of theology, and it is not confined to any particular school or body.

718. Objections of Equiprobabilists.--(a) The praise given to St.
