I. Two common errors present themselves to me with respect to the subject-matter of this discourse, the one theoretical, the other practical. The theoretical is derived from lying among men being reputed as infamous, or as a vice nearly bordering upon infamy. Let us admit, for argument’s sake, the divisions the theologians make of a lie, into officious, jocose, and pernicious. Let us admit also, that a pernicious lie is reputed in the common opinion as it deserves to be reputed, and that it is treated with all possible abhorrence, so that those who are noted for telling lies to the prejudice of their neighbours, are generally considered as the pests of society; but notwithstanding all this, my remarks will be principally confined to officious and jocose lies; that is, to such as are not intended to injure a third person, but are only told to entertain, or because they may be of some utility to a man’s self, or to some other person. I must also premise, that I mean to treat this point more as a politician, than as a moral theologian. The theologians estimate officious, and jocose lies, as venal sins; nor should I or any one else in a moral light, represent them blacker. But if viewed in a political light, my sentiment is, that the common opinion is excessively favourable and indulgent to this species of vice. II. And what is the reason of this excessive indulgence? Why the reason is, because this sort of lie is not considered as an affront offered to any man. The being noted for an officious or jocose liar, does not take from any man the honour, which in other respects is thought due to him. A gentleman, let him tell as many of these sort of lies as he will, is still looked upon as a gentleman; a nobleman also, notwithstanding his being remarked for this vice, is considered as a nobleman, and a prince as a prince. But this appears to me repugnant to all reason. Lying is infamous, bad, and vile; and a liar is unworthy of human society; he is an impostor, who traiterously avails himself of the good faith of other men, in order to deceive them. The most precious intercourse among men, is that of a frank and reciprocal communication of their souls; with which, they in conversation lay open and disclose to each other, the affections of their wills, the sentiments of their mind, and all that is treasured up in their memories. Now what is a liar, but a solemn circumventor of this inestimable commerce? what, but a deceiver, who imposes on us delusions for realities? what but a circulator of false money, who passes the iron of a lie for the gold of truth? and finally, what can there be found in this man, that should excuse him from being discarded and rejected by all others, as a nuisance to company, a vile contaminator of conversation, and as a detestable falsifier of all intelligence and information?
