(b) The supposition that there must always be some special reason of good to offset the evil of the danger of material sin is not correct. For there always exists a compensation proportionate to the danger, namely, the exercise of liberty, a great gift of God, and the avoidance of the burden of fulfilling all uncertain obligations. 736. Reply of the Compensationists.--(a) The principle that a doubtful law obliges doubtfully means only that the reasons in favor of the law deserve some consideration, and should not be put aside unless one has some better reason than mere arbitrariness, self-will, or the intention to take always the easier way. There is no question of either Tutiorism or hesitation, but only of a prudent and honest facing of the fact that there are two sides to one’s doubt. (b) It is not true that the exercise of liberty and the escape from the burden of uncertain obligations are always a sufficient compensation for the danger of material sin. For material sin is not only an evil in itself, as being a violation of law; it is also the source of many and great evils both to the individual and society, such as wrong habits acquired, scandal given, etc. Liberty is a great gift, but it should not become a cloak for malice. Neither is the foregoing of liberty so great an evil that one should not be willing to suffer it now and then in order to prevent the greater evils spoken of just above. 737. Other Objections Against the System of Compensation. (a) From Authority.--Compensationism is of very recent origin, and it cannot be admitted that the right solution of moral difficulties was unknown before this new system appeared. (b) From Reason.--It runs counter to the principle commonly accepted in the controversies of the systems, namely, that the decisive factor as to obligation in doubt is knowledge. For it introduces a new factor, that of sufficient reason or compensation. (c) From Serviceability.--It is easy to say in the abstract that one should always have a suitable reason for adopting a probable opinion in favor of liberty. But, when one attempts to apply this rule to actual cases, difficulties innumerable arise (searchings of motives, comparison of probabilities, measuring of consequences, etc.), so that for use Compensationism is impossible, or impracticable. 738. Reply of Compensationists.--(a) Compensationism is an example of doctrinal progression from the implicit to the explicit. The principles on which it is based are found in the teaching and practice of the most ancient authorities. (b) Sufficient reason is not a new principle, since it is admitted by all moralists for the case of double effect (see above, 102 Sqq.); its application to the solution of doubts of conscience is not an innovation, since the cases of doubt and of double effect are analogous.
