606. Is a lax person held responsible, if he does not know that he is lax? (a) If his conscience is invincibly erroneous, he cannot know that it is lax, and hence he is not responsible; (b) if his conscience is vincibly erroneous, he ought to know that he is lax, and hence he is responsible. Examples: The boy Caius keeps whatever he finds, because he thinks he has a right to do this. The man Titus does not like cheating, but he cheats habitually, because he thinks he has as much right to do so as others. Both the boy and the man are lax, but neither considers himself lax; the difference is that Titus can and ought to know that he is lax. 607. The scrupulous Conscience.--This is a species of erroneous judgment that sees sin where there is no sin, or grave sin where there is only light sin, and whose reasons are trivial or absurd. (a) It differs, therefore, from a strict or tender conscience, which, while it does not exaggerate sin, judges that one should try to avoid even slight sin and imperfection. This is the golden mean between a lax and a scrupulous conscience. Persons with this sort of conscience are sometimes called scrupulous or singular, because they are more exact than the majority. More accurately they are to be called conscientious or God-fearing. (b) The scrupulous conscience differs also from scrupulosity, which is a state of mind in which one whose judgment is not erroneous, is nevertheless tormented by fears or doubts about his moral condition. 608. The rules given above (588 sqq.) for the erroneous conscience apply also to the scrupulous conscience. (a) He who follows a scrupulous conscience does not sin by this, even though he is vincibly in error; for there is no danger of sin in doing more than is required. Example: Caius is too lazy to make inquiries about his religious duties, but he has the exaggerated notion that grace at meals obliges under pain of grave sin. He does not sin by following his conscience, for grace at meals is recommended to all. (b) He who disobeys a scrupulous conscience commits the sin his conscience apprehends. Example: If Caius omits grace, he is guilty of grave sin. 609. Special Dangers of a scrupulous Conscience.--(a) As to himself, the scrupulous person suffers from his conscience; it makes him guilty of sin where there should be no sin, and by its exaggerated strictness it often drives him to the other extreme of laxity. (b) As to others, the scrupulous person is an annoyance and a detriment; he tries to impose his conscience on them, or at least he makes virtue appear forbidding.
