In case it should happen that these business interests of the nation's businessmen interested in trade or investments abroad are jeopardised by a disturbance of any kind in these foreign parts in which these business interests lie, then it immediately becomes the urgent concern of the national authorities to use all means at hand for maintaining the gainful traffic of these businessmen undiminished, and the common man pays the cost. Should such an untoward situation go to such sinister lengths as to involve actual loss to these business interests or otherwise give rise to a tangible grievance, it becomes an affair of the national honour; whereupon no sense of proportion as between the material gains at stake and the cost of remedy or retaliation need longer be observed, since the national honour is beyond price. The motivation in the case shifts from the ground of material interest to the spiritual ground of the moral sentiments. In this connection "honour" is of course to be taken in the euphemistic sense which the term has under the _code duello_ governing "affairs of honour." It carries no connotation of honesty, veracity, equity, liberality, or unselfishness. This national honour is of the nature of an intangible or immaterial asset, of course; it is a matter of prestige, a sportsmanlike conception; but that fact must not be taken to mean that it is of any the less substantial effect for purposes of a _casus belli_ than the material assets of the community. Quite the contrary: "Who steals my purse, steals trash," etc. In point of fact, it will commonly happen that any material grievance must first be converted into terms of this spiritual capital, before it is effectually turned to account as a stimulus to warlike enterprise.
