lying and the mistrust which lying generates. But although this is true, yet lying must be avoided primarily because it is unworthy of the dignity of man; it is a perversion of right order; it is intrinsically, in itself, wrong.
Some of the Greek Fathers held a different view from the above, and thought that lying was not wrong under all circumstances, but that it was occasionally allowable, like medicine, on account of inevitable necessity. English moralists have very commonly held a similar opinion, that a lie is only told when what is false is said to one who has a right to the truth. Some modern Catholic theologians have also adopted this opinion, which places the malice of lying in the denial of the truth to one who has a right to it. They do not, however, sufficiently explain the nature of that right, whether it is a strict right of justice, or a right in a vague sense demanded by the good of society, and so due out of legal justice, or charity, or piety, or obedience. Moreover, it is as difficult to determine when that right exists as it is to determine what is a lie according to the common opinion, and the door seems to be opened to promiscuous lying provided that no injury be done to our neighbour. The only lie which the theory acknowledges seems to be the hurtful lie. Nor does it sufficiently answer the arguments on which the common opinion is based.
3. If it is never lawful to tell a lie, if the lie of necessity cannot be allowed, what means have we of safeguarding a secret?
Catholic theologians answer this question by propounding their doctrine of mental reservation. Mental reservations are either strictly or widely so called. The former is the restriction of one's meaning in making an assertion to the proposition as modified by some addition made to it within the mind of the speaker. As if on being asked " Are you going to town?" one were to answer " Yes," meaning " in imagination." In wide mental reservations the words used are capable of being understood in different senses, either because they are ambiguous in themselves, or because they have a special sense derived from the circumstances of time, place, or person in which they are spoken. Thus, when a servant says that her master is not in, the words may mean either that he is absent, or that he does not wish to see the visitor. The servant's real meaning is restricted to one of these senses. In the same way a defendant on his trial in an English court of justice pleads not guilty i.e., until the charge be proved. A lawyer or a doctor questioned about professional secrets replies, " I
