_Quest._ VII. But though it be a sin, it remaineth doubtful whether it be a lie. _Answ._ This is but _lis de nomine_, a controversy about the name and not the thing. As long as we are agreed that it is a sin against God, and to be avoided, whether you call it a lie, or by another name, is no great matter. But I think it is to be called a lie: though I know that most definers follow Cicero, and say that a lie is a falsehood spoken with a purpose to deceive; yet I think, that where the will is culpably neglective of not deceiving, an untruth so negligently uttered deserveth the name of a lie.
_Quest._ VIII. Must my words, to free them from falsehood, be always true in the proper, literal sense? _Answ._ No. Augustine's determination in this case is clear truth, _Quod figurate dicitur non est mendacium, (i. e. eo nomine)_. To speak ironically, metonymically, metaphorically, &c. is not therefore to lie. For the truth of words lying in that aptitude to express the thing and mind, which is suited to the intellect of the hearers, they are true words that thus express them, whether properly or figuratively; but if the words be used figuratively, contrary to the hearers, and the common sense of them, with a purpose to deceive, then they are a lie, notwithstanding you pretend a figure to verify them.
_Quest._ IX. Must my words be used by me in the common sense, or in the hearer's sense? _Answ._ No doubt but so far as you intend to inform the hearer, you are to speak to him in his own sense. If he have a peculiar sense of some word, differing from the common sense, and this be known to you, you must speak in his peculiar sense. But if it be in a case that you are bound to conceal from him, the question is much harder. Some think it an untruth and sinful to speak to him in words which you know he will use to his own deceit. Others think that you are not bound to fit yourselves to his infirmity, and speak in his dialect contrary to common sense; and that it is not your fault that he misunderstandeth you, though you foresee it, where it will not profit him to understand you, nor yourselves are obliged to make him understand you, but the contrary: the next will open this.
