History furnishes us with innumerable examples of deceptions practised with success upon an enemy, by assuming his arms, ensigns, colours, or uniforms; all which may be justified upon the same principle. For all these are actions, which any one may avail himself of at his pleasure, by departing from the usual course of his military system. For such points of discipline and system depend upon the will and fancy of the military commanders in each state, rather than upon any invariable custom, equally binding upon all nations. IX. Those signs, by which the daily intercourse of life is maintained, form a subject of more weighty discussion, with which the consideration of lies or falsehood is necessarily interwoven. All stratagems of this kind are so direct a violation of all moral principle, both in their nature and consequences, that almost every page of the revealed will of God declares their condemnation. Solomon describes a righteous, that is, a good man, as one, who holds every false word in detestation, deprecating the least appearance of deception: and the Apostle's injunction accords with these sentiments, instructing his disciples not to lie to one another. Nor is it in the high standard of perfection alone, which the divine records present, that such a recommendation of fair, open, and sincere dealing is to be found. It is the theme of praise with poets and philosophers, and the angry hero of the Grecian poet declares, that he detests the man, as an infernal being, who utters one thing with his tongue, while he conceals another in his heart. But making some allowance for poetic fiction--we find even the grave, sober, and discerning, Stagirite describing falsehood, as a vile, and abominable refuge, and painting truth as a lovely object, that must extort the warmest praise. These are all great and high authorities in favour of open dealing. Yet there are names of no less weight, both among sacred and profane writers, whose opinions are a vindication of stratagems, when used upon PROPER occasions. One writer speaks of a case, where stratagem may be used, even for the benefit of the person, on whom it is practised, and adduces the instances of a physician, who, by means of a deception, overcame the perverseness of a patient, and wrought a salutary cure. X. To reconcile such a variety of discordant opinions, it may be necessary to devise some way of examining falsehood both in its more extensive, and more confined acceptation. Nor is speaking an untruth, UNAWARES, to be considered in the nature of a lie, but the falsehood, which comes within the limits here defined, is the KNOWN and DELIBERATE UTTERANCE of any thing contrary to our real conviction, intention, and understanding.
