The considerations set out in earlier chapters have made it appear that the patriotic spirit of modern peoples is the abiding source of contention among nations. Except for their patriotism a breach of the peace among modern peoples could not well be had. So much will doubtless be assented to as a matter of course. It is also a commonplace of current aphoristic wisdom that both parties to a warlike adventure in modern times stand to lose, materially; whatever nominal--that is to say political--gains may be made by one or the other. It has also appeared from these considerations recited in earlier passages that this patriotic spirit prevails throughout, among all civilised peoples, and that it pervades one nation about as ubiquitously as another. Nor is there much evidence of a weakening of this sinister proclivity with the passage of time or the continued advance in the arts of life. The only civilized nations that can be counted on as habitually peaceable are those who are so feeble or are so placed as to be cut off from hope of gain through contention. Vainglorious arrogance may run at a higher tension among the more backward and boorish nations; but it is not evident that the advance guard among the civilised peoples are imbued with a less complete national self-complacency. If the peace is to be kept, therefore, it will have to be kept by and between peoples made up, in effect, of complete patriots; which comes near being a contradiction in terms. Patriotism is useful for breaking the peace, not for keeping it. It makes for national pretensions and international jealously and distrust, with warlike enterprise always in perspective; as a way to national gain or a recourse in case of need. And there is commonly no settled demarkation between these two contrasted needs that urge a patriotic people forever to keep one eye on the chance of a recourse to arms.
