5. THE CODES OF COMMUNITES: VERACITY.--As to veracity: It has undoubtedly been valued to some degree, and with certain limitations, by tribes and nations the most diverse in their degrees of culture. Did men never speak the truth they might well never speak at all. But to maintain that absolute veracity has at all times been greatly valued would be an exaggeration. The lie of courtesy, the clever lie, the lie to the stranger, have been and still are, in many communities both uncivilized and more advanced, not merely condoned, but approved. With the defence which has been made of the doctrines of mental reservation and pious fraud students of church history are familiar. In diplomacy and in war today highly civilized nations find deceptions of many sorts profitable to them, nor are such generally condemned. [Footnote: WESTERMARCK, II, chapters xxx and xxxi.] What modern government does not employ secret service agents, and value them in proportion to the degree of skill with which they manage to deceive their fellows, while limiting the exercise of professional good faith to their intercourse with their paymaster? The secret service agent of transparent frankness, who could not bear to deceive his neighbor, would not hold his post for a day. He would be a subject for Homeric laughter. Moreover, if the question may be raised: what constitutes justice? may one not equally well ask: what constitutes veracity or its opposite? Where does the silence of indifference shade into purposed concealment, and the latter into what is unequivocally deception? At what point does deception blossom out into the unmistakable lie? One may take advantage of an accidental misunderstanding of what one has said; one may use ambiguous language; one may point instead of speaking. Between going about with a head of glass, with all one's thoughts displayed as in a show-case to every comer, and the settled purpose to deceive by the direct verbal falsification, there is a long series of intermediate positions. The commercial maxim that one is not bound to teach the man with whom one is dealing how to conduct his business, and the lawyer's dictum that the advocate is under no obligation to put himself in the position of the judge, obviously, will bear much stretching. 6. THE CODES OF COMMUNITIES: THE COMMON GOOD.--Nor are the facts which confront us less perplexing when we turn to that "regard to the common good" which Butler finds to be acknowledged and enforced by the primary and fundamental laws of all civil constitutions. Whether we look at the past or view the present, whether we study primitive communities or confine ourselves to civilized nations, we see that common good is not, apparently, conceived as the good of all men, however much the words "justice" and "humanity" may be upon men's lips.
